Abstract Climate‐smart agriculture (CSA) serves as a credible mechanism to simultaneously address food security, climate change, and agricultural productivity. Despite the widespread adoption of CSA approaches across West Africa, many countries have still not been able to resolve the problems of food insecurity and rural poverty. This systematic review evaluates published evidence on the types of CSA practices, the determinants and benefits of adoption, and the barriers confronting the adoption of CSA practices across West Africa, following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses statement checklist. Articles published in English from January 2010 to March 2023 investigating the benefits of and barriers to the adoption of CSA practices in West Africa were retrieved from ScienceDirect, Web of Science, and Scopus databases. The methodological quality of studies was assessed using Joanna Briggs Institute critical appraisal tools for use in systematic reviews. The themes emerging from the articles were extracted, and a summary was provided to illustrate each theme. After applying the eligibility criteria, 12 articles were included in the final review. The studies reviewed revealed that farmers used more knowledge‐, water‐, carbon‐, and nitrogen‐smart practices, compared to weather‐ and energy‐smart practices. Across the reviewed papers, factors such as the education level of farmers, age, gender, household size, membership of a social group, agricultural extension services, and access to credit/financial resources influenced CSA adoption. The reviewed studies identified that farmers who used CSA practices reported benefits such as improved soil fertility, higher yield, improved household income, climate resilience (such as overcoming the effects of drought and extreme temperatures), and food security. Some farmers adopted CSA practices to reduce the effect of droughts and high temperatures on their crops, and thus increase their resilience to climate variability and change. However, farmers’ adoption is confronted with challenges related to the technicality of some CSA practices, high cost of labor for CSA implementation, lack of credit and government support, limited access to weather and climate information, limited information about CSA options, high illiteracy level of smallholder farmers, and incompatibility of some practices with farmers’ crop of interest. Our findings show that most CSA practices in the studies we reviewed are not well targeted to meet farmers’ crop of interest, and that governments should provide more practical training to enhance farmers’ understanding of CSA practices, especially those related to weather‐ and energy‐smart initiatives. There should also be more robust financial and institutional support to improve the adoption and usage of CSA practices at all levels. Additionally, socio‐cultural factors such as values, customs, and beliefs should be properly integrated into CSA plans as they influence the adoption of CSA practices.

Land use changes affect soil and biomass carbon sequestration potential of the agroecosystems of most Sub-Sahara Africa facing rising temperatures due to global climate change. One such ecosystem is the Owabi reservoir catchment in Ghana, which has undergone extensive changes in land use through urbanization. Our study aimed to determine the impact of the spatial and temporal variability of the different land uses on soil and biomass carbon storage in the Owabi catchment. Land use/cover maps were elaborated using SPOT satellite images of 30 × 30-m resolution and Erdas Imagine and ArcGIS Pro softwares. Soil and vegetation were sampled along three transects in the Y plane in early 2014. Nested plot design and temporary sample plots of 50 × 50 m were demarcated within a 1 ha plot in each of the land uses. Trees, herbs and litter were sampled to assess aboveground carbon, and soil samples were taken at 0–15 cm and 15–30 cm depth. Belowground (root) biomass was calculated using the root:shoot ratio. Seven (7) land use types – dense forest, sparse forest, grassland, cropland, wetland, settlement, and excavated land – were identified and differences in carbon stocks were assessed. Soil carbon stock (0–30 cm) ranged from 51.80 Mg/ha in dense forest to 7.00 Mg/ha in excavated land. Our study showed that the conversion of forest lands to other land uses through excavation resulted in about 30-folds loss in carbon and also a major loss of carbon in the catchment from c. 1.4 × 106 Mg C in 1990 to 0.55 × 106 Mg C in 2014. Enhancing forests or growing trees to sequester carbon seems to be the optimum choice among the seven land uses if the introduction of payment for environmental services options is considered.

Climate change adversely impacts food and feed production, depletes water, and increases the vulnerability of the people living within arid and semi-arid areas. The current study aims to assess crop–livestock water productivity within such drought-recurrent or water-stressed regions. This was done through secondary data collection and interviews from 589 households across the Sudan, Sudan–Sahel, and Sahel climatic zones of Burkina Faso. The findings confirm that the feeding strategies of livestock were based essentially on natural pasture, crop residues, and agricultural by-products. Moreover, crop–livestock total water productivity (TWP) was found generally higher in the Sudan zone (0.29 ± 0.02 $US/m3) characterized by more favorable climatic conditions than the Sudan–Sahel and Sahel regions that experienced a similar TWP (0.21 ± 0.01 $US/m3). The research gives insight into the valuation of virtual water contained in livestock feeds. Improving the accessibility in quantity and quality of such feeds through informed policy actions could enhance returns on transpired water. Additionally, other water harvesting and conservation methods are also essential to sustain more productive crop–livestock systems within water-stressed regions like Burkina Faso. HIGHLIGHTS Water productivity in the mixed-crop–livestock system varied with the climatic gradient from the Sudanian zone to the Sahelian zone.; Appropriate use of virtual water contained in crop residues contributes to better-transpired water productivity.; Policy actions must support accessibility in quantity and quality to animal feed to ensure more yields per drop of water.;

Abstract Gender‐differentiated roles, responsibilities, access, rights, and knowledge gaps shape women's vulnerability to climate change. This is especially critical for women farmers whose livelihoods are climate‐dependent. A key component in building women farmers’ resilience to climate change is deepening their adaptive capacity. Therefore, this research sought to measure the adaptive capacity of women farmers from two unique districts of Ghana using the sustainable livelihood capitals and investigate how access to climate information and the uptake of climate action can influence women's adaptive capacity. Rural women farmers (n = 497) were interviewed through a survey and supported with key informant interviews from six agricultural staff at the selected districts. The adaptive capacity of respondents was rated moderate at 0.405. Differences between the adaptive capacity of women from different agroecological zones (Dormaa East—0.422; East Gonja—0.388) were statistically insignificant (p > 0.05). All climate information mediums except the TV medium had a significant prediction on women farmers’ adaptive capacity. The odds of a decreasing relationship of predictor variables, such as extension officer medium, radio, and adaptation action, require strategic structuring to accrue holistic benefit. The study thus recommends deepening women's benefit from extension services by attracting and retaining female extensionists, while training extensionists on tailored techniques for engaging female farmers. Again, extensionists who report high outreach to female farmers should be incentivized. Traditional and modern Information and Communication Technology mediums must be explored and integrated as alternatives. Co‐benefit practices for both adaptation and mitigation should be encouraged among women farmers to deepen climate action.

Understanding past climate trends and their impacts in the Sahel region is fundamental for climate change (CC) adaptation and mitigation. This study analyses climate trends from 1961 to 2020 in three climatic zones in Burkina Faso and the impacts of CC on five major crops production. Long time series of daily rainfall and temperature data from National Meteorology Agency for the period 1961 to 2020 has been compiled. Crop production data (1984–2020) were retrieved from the agriculture department. Climate temporal variations in each climatic zone were analyzed using extreme climate indices and principal component analysis. Linear regression was used to assess climate impacts on crop production. The results showed a high rainfall variability and changes in temperature extremes in the three zones. The climate window, 1991–2020, was hotter than 1961–1990, while the last decade (2011–2020) was the wettest. Most climate indices (67%) showed significant correlations with crop yields. Dry spells, cool days, cold nights, average daily wet days and rainfall intensity showed positive and negative effects on maize, cowpea, millet and sorghum yields. This study highlights the importance of climate-smart policy promoting drought-resistant and short-duration varieties in addressing the adverse effects of CC on crop production. HIGHLIGHTS The warm tails of the daily temperature distributions are changing faster than the cold tails witnessing a warming climate in Burkina Faso.; Recent decade was wetter across the Sahelian and Sudano-Sahelian zones, supporting rain resumption and the Sahel greening hypothesis.; The major crops were differently affected by climate extremes and were more sensitive to these extremes than the average climate conditions.;

The impacts of climate change on crop yields are receiving renewed interest, with focus on cereals and staple crops at the regional and national scales. Yet, the impacts of climate variability on the yields of leguminous crops in the local context has not been explored. Thus, an in-depth understanding of climate change variability in the local context may support the design of locally relevant adaptation responses to current and future climate risks. This study examined the impacts of climate variables (annual rainfall, annual average temperature, rainfall indices (rainfall onset, rainfall cessation, and the length of rainy days), and the number of dry days) on the yields of leguminous crops (groundnuts, cowpeas, and soybeans) in the Guinea Savanna agroecological zone of Ghana during the period of 1989–2020. The data were analysed using Mann-Kendall's trend, Sen's slope test, correlation analysis, and Multiple Regression Analysis (MRA). The findings revealed that annual rainfall, annual average temperature, rainfall onset, rainfall cessation, and the length of rainy days, and the number of dry days all showed varied impacts on the yields of groundnuts, cowpeas, and soybeans. The trend analysis detected a marginal decrease in the amount of rainfall, rainfall onset, and the number of dry days from 1989 to 2020 (P ​> ​0.050). Annual average temperature and the length of rainy days substantially varied (P ​

We assessed how people adapt to climate change in the context of forests through a systematic review of the international empirical research literature. We found that drought, precipitation variability, extreme precipitation and flooding, and extreme heat were the climatic stressors to which responses were most frequently documented. Individuals and households received the most research attention, followed by national government, civil society, and local government. Europe and North America were the geographic foci of more research than other regions. Behavioral responses were more reported than technical and infrastructural responses and institutional responses. Within these types of responses, actors used a wide variety of practices such as replanting, altering species composition, and adopting or changing technology. Adaptation efforts in early planning and advanced implementation received some attention, but early implementation and expanding implementation were most reported. While connections between responses and risk reduction were discussed, there is limited evidence of risk reduction. Our review contributes to the scholarly and practical understanding of how people adapt to climate change in the context of forests. The review also identifies opportunities for future research on adaptation to other climatic stressors, such as wildfires and tree pests and pathogens, adaptation in other geographic areas, especially Oceania, and adaptation by actors beyond the individual and household level and through institutional adaptation efforts.

Climate smart agriculture (CSA) has been promoted by governments and international development institutions as an intervention to address climate change and deliver triple wins. Yet, the trade-offs and synergies associated with CSA practices have not been explored. This study develops composite indices for prioritizing CSA practices to better inform policy about their trade-offs, synergies and acceptability. The aim of this study was to examine smallholder farmers’ uptake of CSA practices, the drivers of such uptake and the benefits (positive and negative) of CSA practices on agriculture, livelihoods and the environment. We employed the Analytic Hierarchy Process with workshop participants across two study districts in Ghana’s transitional and Sudan savannah agroecological zones. Results showed differences in CSA practices prioritized for achieving the productivity, adaptive capacity and mitigation goals between the two agroecological zones. Results also showed synergies and trade-offs associated with the implementation of CSA interventions, for example, irrigation may increase farm productivity (synergy) while contributing to the emission of greenhouse gases (GHGs) simultaneously (trade-off). Additionally, there are various perceived acceptance and efficiency levels of CSA practices by smallholder farmers and agricultural development officers. These results have implications for the implementation of future CSA action plans in vulnerability hotspots in dryland farming systems.

ABSTRACTLand use change has led to drastic soil degradation and greenhouse gas emissions with implications for sustainable agriculture and climate change. Here, we report soil carbon stock and nutrient compositions of four land use types in the forest-savanna transition agro-ecological zone of Ghana. These were cashew, mango, oil palm and arable land. Soil samples were collected at 0–15 cm and 15–30 cm depths from each land use type. Soil nutrients and organic carbon content were greater in the tree-based land use types than in the arable land. Total soil organic carbon (SOC) ranged from 1.71% under cashew to 1.12% under the palms at the 0–15 cm depth. Soil carbon stock under the cashew was 12.5% greater than that of mango (56 Mg C/ha), and 40% more than that under oil palm. However, active carbon or permanganate oxidizable carbon was greatest (~130 mg/kg) under mango and least (~92.6 mg/kg) in arable land in the surface soil. Overall, active carbon was dependent on soil total carbon in the land use types (r = 0.81–0.91). Soil microbial biomass carbon was least in arable land (p 0.05) at 0–15 cm depth. No clear trend was observed in the exchangeable base compositions in the surface soils but cashew and mango systems appeared to show significantly greater levels of exchangeable calcium and magnesium, respectively. We conclude that strong nexus between soil microbial biomass carbon, nitrogen and phosphorus, and active soil carbon may drive soil carbon dynamics in land use systems of tropical forest-savanna ecotone.

Agroecological practices are promoted as a more proactive approach than conventional agriculture to achieving a collective global response to climate change and variability while building robust and resilient agricultural systems to meet food needs and protect the integrity of ecosystems. There is relatively limited evidence on the key traditional agroecological knowledge and practices adopted by smallholder farmers, the factors that influence smallholder farmers’ decision to adopt these practices, and the opportunities it presents for building resilient agricultural systems. Using a multi-scale mixed method approach, we conducted key informant interviews (n ​= ​12), focus group discussions (n ​= ​5), and questionnaire surveys (N ​= ​220) to explore the traditional agroecological knowledge and practices, the influencing factors, and the opportunities smallholder farmers presented for achieving resilient agricultural systems. Our findings suggest that smallholder farmers employ a suite of traditional agroecological knowledge and practices to enhance food security, combat climate change, and build resilient agricultural systems. The most important traditional agroecological knowledge and practices in the study area comprise cultivating leguminous crops, mixed crop-livestock systems, and crop rotation, with Relative Importance Index (RII) values of 0.710, 0.708, and 0.695, respectively. It is reported that the choice of these practices by smallholder farmers is influenced by their own farming experience, access to market, access to local resources, information, and expertise, and the perceived risk of climate change. Moreover, the results further show that improving household food security and nutrition, improving soil quality, control of pest and disease infestation, and support from Non-Governmental Organizations (NGOs) and local authorities are opportunities for smallholder farmers in adopting traditional agroecological knowledge and practices for achieving resilient agricultural systems. The findings call into question the need for stakeholders and policy-makers at all levels to develop capacity and increase the awareness of traditional agroecological knowledge and practices as mechanisms to ensure resilient agricultural systems for sustainable food security.

Abstract This paper reviewed a body of literature on climate adaptation options in sub‐Saharan Africa's (SSA) smallholding agriculture and complemented it with a case study involving experts interviews, focus group discussions, large‐scale household surveys, and farmer practices observation while drawing insight from the concept of “everyday adaptation and interrupted agency” and agency theory to assess farmer perceived limitations with climate‐smart agriculture (CSA) and climate‐wise food systems (CWFS) practices for climate adaptation in the SSA. The study noted that the narrow focus on CSA and/or CWFS as a silver bullet for climate change adaptation suitable for smallholding agriculture ignores food producers’ agency to undermine sustainable and inclusive adaptation solutions. Moreover, smallholder farmers’ everyday climate adaptation practices could be grouped into three categories; on‐farm adaptation, off‐farm adaptation, and Indigenous agroecological adaptation options. The on‐farm adaptation options are usually agriculture intensification and extensification. The off‐farm adaptation options include livelihood diversification activities, petty trading, seasonal labor jobs, and migration. The Indigenous agroecological adaptation strategy uses observing nature and weather elements to predict the onset of the rainy season. The study noted that smallholders’ adaptation options, which is an expression of their agency, are motivated by smallholders’ desire to be resilient to changing climate, increase productivity and income, and social network influence but not necessarily because the strategy is being promoted by the government or Non‐Governmental Organizations (NGOs). Therefore, we propose a sustainable food agency (SFA)—a multifaceted blended constellation of climate adaptation and mitigation strategies, as the best approach to addressing the climate crises in the SSA. The SFA allows individuals or groups to decide what climate change adaptation options best work for them to adapt to changing climate and produce and distribute their food without undermining the economic, social, and environmental bases that generate food security and nutrition for present and future generations.

Abstract A major limiting factor affecting the uptake of conservation agriculture practices in smallholder farming systems in sub‐Saharan Africa is the limited availability of sufficient crop residues for use as surface mulch. This paper assesses the trade‐offs in crop residue utilization among smallholder farmers and its implications for soil management in the face of climate change risks in northern Ghana. The paper triangulated data from 350 household surveys with participatory key informant interviews from seven selected communities in three districts of northern Ghana. The problem confrontation index (PCI) was adopted to identify and rank the challenges associated with farmers’ decision to use crop residues, while a multivariate probit model was used to analyse and predict the factors that influence farmers’ choice of crop residue management practices. Results showed that crop residues were used as cooking fuel in households (21%), livestock feed (21%), left on the farm to decompose as mulch (34%) or burned to clear the land (24%). Key challenges identified included high labour cost (PCI = 404), high labour intensity (PCI = 388), the cost and transport for collection and storage of externally sourced crop residue (PCI = 383) and the low benefit from crop residue to farm output/soil fertility (PCI = 339). Results from the multivariate probit model revealed that household and farm variables, institutional and socio‐psychological factors, and experience of some climate shocks all influence farmers’ choice of crop residue management practices. Crop residue use and management practices adopted were determined by factors including the crops being grown, challenges faced by farmers and the management options available. The study recommends the need for the Government of Ghana to empower farmers through the provision of technical knowledge and machinery for the sustainable utilization of crop residues due to the high labour intensity and cost associated with such practices.

Climate adaptation, while urgent, is complicated by a slew of unknowns and uncertainties through insufficient scholarship. This study addresses these slews of unknowns surrounding local adaptation to climate change and associated determinants among rainfed smallholder farmers in rural Ghana. We utilized a mixed-method approach to collect primary data from 410 households, 15 key informants and 10 focus group participants coupled with meteorological data from the Ghana Meteorological Agency, Accra (GMet). Results from meteorological analysis from 1989 to 2020 and farmers' perceptions showed a consistent pattern exemplifying a temperature rise, and a decline in rainfall pattern in the study area over the period. Rainfed smallholder farmers employed multiple coping strategies including—cognitive restructuring, resource seeking, experiential avoidance, expressive coping, capital disinvestment and relying on social networks to deal with current and future climate shocks. Also, key adaptation interventions implemented by rainfed smallholder farmers based on lived experiences include farm and crop management, soil and water conservation, conservation agricultural practices, smart-farming practices and cropping decisions, livelihood diversification and indigenous knowledge application. Market access, access to climate information/services, access to extension services, use of indigenous knowledge and practice, risk perception, and government support, livestock ownership, asset ownership, credit access, and farm insurance significantly increase rainfed smallholder farmers' decision to cope/adapt to climate variability in rural Ghana. However, improved soil fertility and farm labour significantly influenced rainfed smallholder farmers' adaptation response but not coping. The findings have implications for developing effective adaptation interventions to build resilient agricultural systems and sustainable livelihood in rainfed farming areas.

Climate-smart agriculture (CSA) remains a key strategy for sustaining agricultural systems and achieving food security and nutrition. Despite this, uncertainty remains on how intra-gendered dynamics influence its adoption in dryland farming systems. This study implements both quantitative and qualitative approaches including household surveys, key informant interviews, and focus group discussions to explore how intra-gender dynamics shape the perceptions and adoption of climate-smart agriculture in three selected communities (Katanga, Dakio, and Zonno) in the Bolgatanga East District of the Upper East Region of Ghana. Specifically, the study answers the following research questions: (i) What is the degree of change in rainfall and temperature in the Bolgatanga East District? (ii) How does gender shape the perception of smallholder farmers on climate variability in the study communities? (iii) Which CSA interventions are employed by smallholder farming households in the study communities? (iv) Which socio-demographic factors influence intra-gendered perceptions and adoption of CSA in the study communities? Binary logistic regression was used to identify the factors influencing male and female farmers’ perceptions and adoption of climate-smart agriculture. Rainfall and temperature trends from 2010 to 2020 were analyzed using the Mann-Kendall trend test. We found that over the past ten years, smallholder farmers in the district have seen rising temperatures and erratic rainfall patterns. Less educated female smallholder farmers adopted CSA interventions relative to more educated female farmers. Married male smallholder farmers employed CSA interventions on their farms compared to single and divorced male farmers. The adoption of CSA was higher for female farmers with inherited farmland than for those with rented land. Our results indicate that the source of income and farming experience influence male smallholder farmers’ adoption of crop rotation and their decision to diversify crops on their farms. The farmland tenure system, farming experience, and income source of female farmers influence their choice to change planting dates. The study recommends the integration of intra-gendered dynamics in policy reforms to reduce the vulnerability of smallholder farmers with different socioeconomic characteristics to climate variability in Ghana.

This study assessed the adaptive capacity of smallholder cocoa farmers to address the adverse effects of climate variability in the Adansi South District of the Ashanti Region, Ghana. Specifically, the study sought to (i) assess the perception of the smallholder cocoa farmers to climate variability; (ii) determine the perceived effects of climate variability on cocoa production in the district; and; (iii) evaluate the adaptive capacity of the smallholder cocoa farmers to manage climate risks. The study used questionnaire surveys with 150 smallholder cocoa farmers, key informant interviews, and focus group discussions in three selected communities (Afiaso, Tonkoase, and Amudurase). A variety of capital assets (social, financial, human, physical, and natural) were utilized to conceptualize smallholder cocoa farmers’ adaptive capacity. Results showed that the smallholder cocoa farmers reported changes in the onset and duration of rains, rising temperatures, and increasing windstorms in the selected communities. The farmers perceived increased incidence of drought and cocoa failure, the prevalence of diseases and pest invasion, and decreased farmer income as the key adverse effects on their cocoa production. Further, findings also revealed that cumulatively, all the selected communities in Adansi South District had a moderate adaptive capacity (0.531). It is recommended that appropriate policies aimed at enhancing the adaptive capacity of smallholder cocoa farmers must be formulated by policymakers to minimize their vulnerabilities to climate risks.

Provision of weather and climate services are expected to improve the capacity for rural households’ preparedness and response plans to weather shocks. With increase in public investments in developing and communicating weather information on local scale in Nigeria, uncertainty in timescales that meet farmers’ needs and economic value of the information is still poorly understood. It is now a policy concern on whether farmers’ preferences and demands might increase its uptake. This study analyzed the economic value, latent demand, and emerging market of weather and climate information in Central-Southern Nigeria. Farm-level cross-sectional data reveals that 76% of the respondents were willing to pay for improved weather information and early warnings in taking climate smart decisions. Within farmers who showed positive responses, 86% would pay for sub-seasonal to seasonal weather information while 38% would pay for medium and short range weather information respectively. The economic value of sub-seasonal to seasonal weather information was estimated at N1600 ($3.60) per year per capita with total aggregated value of N1.3 billion ($2.9 m) yearly for the derived savannah area. Predictive total market value of N17.43billion ($39 m) would be obtained from improved weather information in Nigeria. Simulated results of 5% increase in the uptake with better dissemination channel through mobile phones in addition to robust farmers’ oriented features will generate additional annual market value at N86m ($193,360) for service providers. Large farm size, good farm-income, mobile phone dissemination channels, and location-specific information were drivers of farmers’ uptake decisions of weather information in the dry savannah area. The huge emerging market for improved weather information should be developed into a public–private market to efficiently facilitate uptake and use in Nigeria.

This study examined the factors that determine the adoption of CSA practices in dryland farming systems. The study answers the following questions: (i) what are the typologies of CSA practices available to smallholder farmers in rural Ghana?, (ii) what is the adoption rate of CSA practices among smallholder farmers? and, (iii) what are the socioeconomic predictors of the adoption of CSA practices in rural Ghana? This paper employed mixed-method participatory approaches including surveys of 1061 households, and 15 key informant interviews supplemented with 2 regional stakeholder workshops. The study used a Principal Component Analysis (PCA) to examine the climate smart agriculture typologies adopted among the smallholder farmers. To investigate the drivers of adoption, the multinomial ordered probit model was applied. The PCA results suggested that, there were seven (7) uncorrelated dimensions involving 23 CSA practices that were generally employed – water smart practices, energy smart practices, nutrient smart practices, carbon smart practices, weather smart practices, planting smart practices, and knowledge smart practices. These 7 typologies explained 63.91% of the total variance. The PCA results indicated that smallholder farmers do not necessarily rely on a single CSA practice to cope with climate change; but utilise a combination of practices. The results of the ordered probit model suggested that the factors driving the adoption of CSA practices are mixed nuanced on the adoption typology and farmers' location and institutional factors. The paper contributes to an understanding of the different typologies for CSA practices and highlights the various socioeconomic factors driving the adoption rates of CSA practices by smallholders' farmers. This is crucial for the upscale of CSA practices in the face of climate change in Ghana and West Africa more widely.

This paper examined the prioritized climate-smart agricultural practices by smallholder farmers, the motivations of adopting climate-smart agricultural practices, the enablers to the successful adoption of climate-smart agricultural practices, and the barriers to the successful adoption of climate-smart agricultural practices in the transitional and savannah agroecological zones of Ghana. Specifically, we employed ethnographic research using participatory approaches, including two stakeholder workshops and household surveys with 1061 households in the transitional and savannah agroecological zones of Ghana. The weighted average index (WAI) and problem confrontation index (PCI) were used to rank smallholder farmers’ perceived enablers to the adoption of climate-smart agricultural practices and the barriers affecting climate-smart agricultural practices, respectively. Results suggest that the majority of the respondents used a suite of climate-smart agricultural practices, including the timely harvesting of produce and storage, emergency seed banking, appropriate and timely weed and pest control, and early planting as practices to build climate resilience. The majority of smallholder farmers primarily employed climate-smart agricultural practices to improve household food security (96.2%), reduce pests and diseases (95.6%), and obtain higher yields and greater farm income (93.2%). Findings also show that secured land tenure system arrangement, understanding the effects of climate change, and access to sustainable agricultural technologies were ranked the first, second, and third most important enablers to the adoption of climate-smart agricultural practices with the WAI values of 2.86, 2.75, and 2.70, respectively. Key barriers to the successful adoption of climate-smart agricultural practices included incidences of pests and diseases (PCI = 2530), inadequate access to agricultural credit (PCI = 2502), high cost of improved crop varieties (PCI = 2334), and limited government support with farm inputs (PCI = 2296). Smallholder farmers need to be better supported through the provision of appropriate institutional and policy arrangements together with improved land management extension advice to overcome these barriers and facilitate the more effective implementation of climate-smart agricultural practices in Ghana.

Amidst the COVID-19 pandemic, the need to accelerate food production efforts to achieve the UN SDG two, i. e., zero hunger target by 2030, is gaining momentum across the global food security discourse. One way to accelerate food production is to adopt improved seeds and technologies that may close existing yield gaps and support food security efforts in regions such as Sub-Saharan Africa. This paper uses mixed methods, including key informant interviews, structured household questionnaire surveys and focus group discussions, to examine the factors influencing the adoption of improved seeds and complementing technologies in Ghana. In particular, we draw insight from theories of failed market-induced behavior, innovation diffusion and induced-innovation theories to explore farmers' perceptions and adoption of different specific improved maize varieties and technologies for agricultural productivity. Our findings suggest that the level of awareness of improved seeds, particularly hybrid seeds and technologies, and the adoption rate of these technologies are low among Ghana's rural farmers. The findings reveal that socio-demographic and economic factors such as gender, age, cost of seeds, the promise of more yields, market access, social networks' influence, seed availability and accessibility are essential determinants of adopting improved planting technologies among smallholder farmers. This paper argues that location and context-specific-targeted extension services delivery to enhance the widespread adoption of improved seeds and technologies across scales can build farmers' capacity to increase agricultural productivity.

The provision of timely and precise weather information could reduce the vulnerability of people to climate change risks. In this study, we conduct a systematic review to synthesize the existing evidence on weather information services for the agriculture, water, and energy sectors of East and West Africa and identify priorities for future research. This systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement checklist. The review identified relevant peer-reviewed publications using ScienceDirect and Scopus databases for original research articles published in English from 2000 to 2022. After applying the eligibility criteria, 25 articles were included in the final review. The themes emerging from the articles were extracted, and a summary was provided to illustrate each theme. The review revealed that weather information studies focus more on the agriculture sector than energy production and water resource management. Users of weather information mainly accessed information related to rainfall and temperature, and the information was accessed mainly through radio, mobile phones, and television. Most of the information provided focused on generic meteorological forecasts instead of tailored impact-based forecasts. Only very few users can access, or benefit from the information produced due to poor communication and technical understanding of weather information. In addition, a lack of downscaled information, logistics, and trust hinders the uptake and use of climate information. Consequently, mainstreaming capacity-building of key stakeholders is required to promote effective adoption and strengthening of climate information services across East and West Africa.Systematic Review Registration: [website], identifier [registration number].

While adaptation interventions offer a window of opportunity to mitigate the susceptibility of mango seedlings to adverse impact of climate variability and change, there is a scarcity of information on how mango seedlings producers respond to climate variability and change in Ghana. Using a qualitative case study with 20 mango seedlings producers selected through purposive and snowball sampling techniques, this study investigates participants’ knowledge and experience of climate variability and change, the effects of the observed changes on mango seedlings and the adaptation strategies employed to counter the risks associated with climate variability and change in a mango production zone of Ghana. Results indicate that floods, droughts, rising temperature, erratic rainfall and windstorm have been observed among the participants, which negatively affect the survival, growth, establishment and quality of mango seedlings. Adaptation strategies, such as creating gutters, applying agrochemicals, grafting and improved seed varieties, planting of trees as shades, irrigation and soil improvement techniques including mulching, have been implemented by the participants to mitigate climate variability and change effects. The practical and policy implications of the results are discussed and recommendations provided.

Weather and climate information trigger early action and facilitate better disaster preparedness. Decision-driven and people-centered weather and climate information are pivotal for the effective uptake. The challenge of early responses in preparing for drought hazard is growing in the dry savannah of tropical sub-Saharan African countries. This paper analyzed user needs for weather and climate information in fostering drought risk preparedness in Central-Southern Nigeria. Stratified, snowball, and simple random samplings were used to obtain a sample of 397 respondents across the agro-ecological zones of Edo State. Structured questionnaire was used to collect farm-level household data across communities. Eight focus group discussions and 11 key informants' interviews were conducted, targeting contact farmers and other agricultural stakeholders in selected key economic sectors of Edo State, Central-Southern Nigeria. Results show that non-users of weather and climate information are more than users in the savannah area. Heckman probit results explained that male gender, farmers' experience, income, and persistent incidence of erratic rainfall have more propensity to facilitate use of WCI in taking critical decisions while group membership or associations and distance of meteorological station prevent stakeholders from developing interest in using WCI for drought preparedness and response. Multi-criteria decision-making indicated that rainfall amount, onset and cessation rainfall dates, and rainfall distributions are the most useful WCI needed by end users in their decision response plan in agriculture; rainfall intensity, rainfall cessation date, rainfall distributions, and length of dry season are ranked as the most useful WCI for water resource management while heat intensity, rainstorms, and drought alerts were ranked as most appropriate for users in the disaster risk reduction in fostering resilience toward anticipated future drought hazard. Subseasonal-to-seasonal (S2S) and medium (4–10 days) timescales information are the most highly rated to facilitate resource planning for efficient utilization and management in all the economic sectors. The users' most preferred delivery method of receiving WCI are mobile telephone, radio, agricultural extension officers, farmers' groups, and contact farmers/specialist for efficiency and convenient criteria in enhancing users' decision capacity to uptake WCI. There is a need for a policy drive to build synergy that will make WCI forecasting systems include impact-based forecast estimates and response advisory across a wide range of natural hazards. A seamless collaborative effort in bringing scientific outputs and users' needs together will increase the utility of WCI through systematic efforts. NiMet should improve on its engagement with the stakeholders, the agricultural extension and planning office, water management authorities, and disaster risk reduction and emergency response personnel as partner institutions. These policy actions would provide a robust collaborative framework for co-producing useable WCI based on user needs in managing decision points against extreme events and mainstream preparedness into existing decision-making apparatus of rural communities in Central-Southern Nigeria.

Understanding gendered adaptation practices among smallholder cocoa farmers is crucial to ensuring sustainable cocoa production in Ghana. This study examined the gendered perceptions and adaptation practices of smallholder cocoa farmers to climate variability in three selected communities (Breman Ayipey, Breman Baako and Breman Kuntanase) in the Asikuma-Odoben-Brakwa District of the Central Region, Ghana. The study adopted a mixed-methods approach including household surveys and focus group discussions with 10 participants in each community. Mann-Kendall trend test was used to determine the rainfall and temperature changes in the study district from 2000 to 2015. Results indicated that there was no significant difference between male and female farmers’ perceptions of climate variability (p > 0.05). Both male and female farmers perceived an increasing temperature, rainfall, windstorms and flooding for the past 15 years. The Mann-Kendall trend test showed that annual rainfall and temperature had increased over the study period although the trends were not statistically significant (p > 0.05). Both male and female farmers had resorted to the use of different adaptation practices to reduce the threats of climate variability. There was a substantial difference between adaptation practices used by male and female farmers such as changing planting dates, use of drought tolerant hybrids, shade management, livestock rearing and income from sale of properties (p

This paper explored the extent to which the awareness of climate change affects the choice of climate change adaptation practice by smallholder pineapple farmers. This study used a cross-sectional data collected from 150 farmers in the Nsawam Adoagyiri Municipality, Ghana. We applied the Latent Class Analysis (LCA) to identify sub-population of pineapple farmers based on their awareness levels of climate change and socioeconomic characteristics. We then used a multinomial logistic regression to examine the extent to which differences in climate change awareness influence adaptation choices. Results indicated that, smallholder pineapple farmers are well aware of climate change and perceived changes in rainfall and temperature patterns. Further, the findings revealed that smallholder pineapple farmers are implementing a host of on-farm and off-farm climate change adaptation practices including irrigation, adjusting planting time, land fragmentation, the use of agro-ecological knowledge, and seasonal migration. The LCA identified three subgroups of smallholder pineapple farmers based on their level of awareness of climate change – strong climate change awareness group (n = 111; 74%), moderate climate change awareness group (n = 18; 12%) and poor climate change awareness group (n = 21; 14%). Results showed marginal differences in the adoption rate of adaptation practices across the observed subgroups of farmers. We identified that institutional factors including the quality of climate information, quality of extension services, access to credit, education and access to extension services have a stronger effect on climate change awareness and the choice of adaptation practice compared to individual factors such as gender, marital status and farmers' age.

Agriculture in Ghana is vulnerable to the adverse effects of climate variability. This poses a challenge to food security across the country. Despite this vulnerability, limited research has been conducted to understand the effect of climate variability on the yields of staple food crops in Ghana. This study assessed the effect of climate variability on the yields of selected staple food crops (millet, sorghum, rice, groundnut and maize). The study used the Mann-Kendall trend test and multiple regression analysis to assess how climate variability (in annual rainfall, onset, cessation, number of dry days and temperature) has affected the yields of selected food crops in five districts in northern Ghana (Bole, Nanton, Tolon, Kassena Nankana East and Wa) over a 21-year period (1995–2016). Results suggested a marginal decrease in annual rainfall (p > 0.05) and a significant increase in temperature (p < 0.05) over the period of study in the districts. Variability in the onset, cessation, length of rainy days and number of dry days was statistically significant from year to year, and also across the districts (p

Ghana's susceptibility to climate change is well documented and the agricultural sector which is the backbone of the country's economy is one of the most vulnerable sectors to the adverse effects of climate change. This study employed both quantitative and qualitative research methods including household surveys and focus group discussions to examine the extent to which traditional agroecological knowledge is used to manage climate change in three selected communities (Gia, Gaani and Nyangua) of the Kassena Nankana Municipality in the Upper East Region of Ghana. The study specifically answers the following research questions: (i) What is the extent of rainfall and temperature changes in the municipality from 1983–2017? (ii) What is the perception of farmers on rainfall and temperature changes in the selected communities for the past three decades? (iii) What are the key adaptation practices used by farmers to reduce the threats of climate change? (iv) What are the traditional agroecological indicators used by farmers to predict rainfall in the study communities? Mann-Kendall trend test was used to assess rainfall and temperature trends over the study period. Results from the trend analysis indicated an inconsistent pattern in rainfall and an increasing trend in temperature in the municipality. Results also showed that farmers perceived decreasing trend in rainfall as well as increasing temperature. Farmers’ perception of decreased trend in rainfall was inconsistent with the analysed rainfall data as the trend of rainfall was statistically insignificant (p>0.05) and Sen's slope confirmed a positive slope indicating that amounts of rainfall had increased in the municipality. The farmers employed a variety of on-farm and off-farm practices including the use of traditional agroecological knowledge, use of improved varieties of crops and temporary migration to adapt to the impacts of climate change in the study communities. The farmers predicted rainfall onset using a variety of traditional agroecological indicators including direction of wind, croaking of frogs, appearance of cattle egret and flowering and fruiting of local trees. The study recommends the putting in place of a framework that blends traditional agroecological knowledge and scientific knowledge to develop effective climate change adaptation strategies.

Empirical evidence on the opportunities and barriers to the uptake of climate services by smallholder farmers for resilient agricultural systems in sub-Saharan Africa is limited. This paper addresses this important gap by evaluating the opportunities and barriers to the uptake of climate information (from short-term weather forecasts, through seasonal forecasts to longer-term climate change information on decadal timescales) by smallholder farmers in the Sudan savannah agro-ecological zone of Ghana. The paper answers the following research questions: i) what kinds of weather and climate information are available and accessible to smallholder farmers for agricultural management decision-making? ii) what opportunities exist for using climate information in agricultural systems in the Sudan savannah agro-ecological zone? iii) what are the key barriers to the uptake of climate information by smallholder farmers in the Sudan savannah agro-ecological zones of Ghana? The study used participatory approaches including household surveys with 555 farmers, 3 stakeholder workshops, 15 key informant interviews and 12 focus group discussions across 6 communities in the Sudan savannah agro-ecological zone. Findings show that more than a third of the study respondents (40%; n = 555) were not receiving climate information. Out of the 60% receiving climate information, the majority (91%; n = 335) indicated receiving information on rainfall with fewer respondents 21% and 26% receiving information on temperature and windstorms, respectively. Radio was the key medium for receiving weather and climate information. Both female and male smallholder farmers were using climate information to make critical farming decisions including time of land preparations (79%), crop variety selection (50%), changing cropping patterns (36%), planting time adjustments (31%), harvesting time (21%) and disease/pest management (10%). Increasing uptake of weather and climate information is confronted with multiple barriers including inadequate information on seasonal forecast for long-term planning, low accessibility of climate information, high levels of illiteracy, difficulties in understanding technical language used in communicating climate information and misalignment between the climate information provided and what smallholder farmers need. Climate information should be linked directly to agricultural impacts and management decision-making to ensure it is both available to, and usable by smallholder farmers.

Whilst the capability of climate services to reduce climate impacts is alluring, empirical evidence on how best to mainstream climate information services in Africa is lacking. This paper determines how climate information services have been incorporated into national policies by Anglophone West African states for building agricultural resilience and provides a detailed analysis of issues facing Ghanaian agricultural systems. The paper addresses the questions: (i) to what extent is climate change recognised as a threat to agricultural development in national climate facing policies of Anglophone West African states? (ii) to what extent have climate information services been incorporated into national and regional policy frameworks of Anglophone West African states for resilient agricultural systems? (iii) what are the key challenges in mainstreaming climate information services into national policies for resilient agricultural building in Ghana? The study employed thematic content analysis, multi-stakeholder workshops and expert interviews to understand climate discourses around climate services. Findings show that climate change is highlighted in national and regional level policies as a serious threat to socioeconomic development and agricultural productivity in West Africa. Anglophone West Africa countries are at various stages in establishing a National Framework for Climate Services to help guide future adaptation planning. This study shows that Anglophone West African states have not yet incorporated climate information services into strategic national and regional climate facing policies that are critical in shaping efforts aimed at managing climate risks. For the case of Ghana, the study reveals low awareness of climate change among policy-makers, human and institutional capacity constraints as some of the key factors militating against the mainstreaming of climate information services. Capacity building of policy makers and institutional strengthening are both vital for more effective mainstreaming of climate services across West Africa.

The importance of extension services in helping smallholder farmers to address the many challenges of agricultural production cannot be over-emphasized. However, relatively few studies have been conducted that investigate how the capacities of agricultural extension agents can be built to more effectively assist smallholder farmers in managing climate risks and impacts. As climate change is a key threat to smallholder food production, addressing this issue is increasingly important. This paper aims to identify how agricultural extension agents in Ghana can better support smallholder farmers in navigating and addressing the effects of climate change on food production. It asks: (i) what are the sources of information used by agricultural extension agents in Ghana’s Upper East region? (ii) what are the capacity building needs of agricultural extension agents for effective communication of climate information for building resilient agricultural systems? (iii) what are the key barriers to successful extension outcomes for climate change adaptation? The paper uses a mixed methods approach including three regional stakeholder workshops, expert interviews and surveys with 32 agricultural extension agents in northeastern Ghana. Results addressing question (i) indicated that radios and television are the dominant sources of climate information for agricultural extension agents in the Upper East region. Findings targeting question (ii) identified capacity building needs such as developing extension agents’ technical skills, improving communication skills, improving knowledge and use of climate smart agricultural interventions such as soil moisture conservation methods, and training on information communication technologies (ICT) to deliver extension advice on climate change. Other needs included developing skills in field demonstration and project monitoring and evaluation. Addressing question (iii), key barriers confronted by agricultural extension agents in the delivery of extension on climate change included lack of transportation facilities for extension agents, lack of appropriate extension materials, high agricultural extension agent to farmer ratios, and inadequate funds to implement adaptation practices. Wider barriers reducing the effectiveness of extension efforts included farmer resistance to change and complex land tenure arrangements that do not allow investment. Periodic workshops should be organised for agricultural extension agents on the use of ICT to deliver extension services, whilst encouraging the use of audio-visuals in extension delivery. These efforts should be supported by regular assessments of extension agents’ capacity building needs.

This study employed a mixed-methods approach to investigate the trends and drivers of land use and land cover changes from 1991 to 2015 in an urban forest reserve in Ghana. The specific objectives were to: i) determine the extent of land cover changes in the urban forest, and ii) ascertain the factors driving land cover changes in the urban forest. The study employed Landsat satellite images using ENVI to detect trends of land cover changes from 1991 to 2015. A questionnaire survey was used to solicit information on the socio-economic drivers of land cover changes from households in four fringe communities of the urban forest. The results showed that built up and bare areas recorded an increase between 1991 and 2015, with a decline in forests as well as shrubs and grasslands. The study showed that, forest decreased from 387.83 ha in 1991 to 341.28 ha in 2015, indicating a class change of 12.0%. Shrubs and grassland also decreased from 24.56 ha in 1991 to 11.77 ha in 2015, representing a class change of 52.1%. Built-up and bare areas changed from 36.278 ha in 1991 to 95.618 ha in 2015, representing class change of 163.57%. Overall, the study established that 59.34 ha of the Achimota Forest Reserve has been lost or converted to built-up and bare areas between 1991 and 2015. Study respondents identified urbanisation as the most important cause of land cover change. Other factors driving land cover changes reported included fuel wood harvesting and logging, agriculture, lack of forest guards, a lack of enforcement of laws on forest and annual fires. Based on these findings, the study concluded that human activities were driving considerable land cover changes in the urban forest. These changes could have significant implications for the long-term sustainability of the urban forest. Therefore, the study recommended that government takes steps to protect the urban forest from further land cover changes, as built up and bare areas have increased by more than double its size since 1991.

While conventional weather forecasts focus on meteorological thresholds for extreme events, Impact-Based Forecasts (IBF) integrate information about the potential severity of weather impacts with their likelihood of occurrence. As IBF provides an indication of local risk, there is an increasing uptake of this approach globally. Despite the vulnerability of West Africa to severe weather, and the potential benefits of such a risk-based approach for informing disaster risk reduction, IBF remains rarely used in this region. To meet this need, three national workshops were held in Ghana, Nigeria and Senegal with forecasters, project researchers and users of Climate Information Services (CIS) from key sectors (e.g., agriculture, water resources, disaster, risk reduction). In addition, a more localized district level workshop was held in Northern Ghana to explore needs at a subnational scale in Tamale District. The objectives of these workshops were to evaluate the current use of forecast products provided by National Meteorological and Hydrological Services (NMHSs) and to explore the potential for applying IBF. Findings indicate a recognition that the quality of forecast products provided by NMHSs in West Africa has substantially improved in recent years. However, challenges remain related to user understanding, clarity about forecast uncertainty, insufficient spatial and temporal resolution of forecasts leading to limited trust in forecasts. The workshops identified high demand for weather information related to storms, droughts and heatwaves in all the three countries. Dust storms were identified as having strong potential for IBF application in both Nigeria and Senegal. To increase the uptake of CIS by users in West Africa, NMHSs will need to develop and implement user-tailored IBF in their normal weather forecast approaches and improve communication channels with user communities. There is an urgent need for governments in West Africa to enhance the capacity of NMHSs to incorporate IBF as a routine forecast activity by first establishing a National Framework for Climate Services with user engagement as a key first pillar.

How climate change adaptation practices can constrain development and deliver maladaptive outcomes in vulnerability hotspots is yet to be explored in-depth using case study analyses. This paper explores the effects of climate change coping and adaptation responses in three case study villages across the Central Gonja district of northern Ghana. The study addresses the following research questions: i) What are the key climatic and non-climatic stressors confronting households in northern Ghanaian communities? ii) How are households adapting to climatic and non-climatic stressors? and iii) What are the outcomes of these coping and adaptation responses on development? The study employs a mixed-method approach including key informant interviews, focus group discussions and household questionnaire surveys. Data identified socioeconomic stressors including a lack of access to (and high cost of) farm inputs, labour shortages and population growth. Climatic stressors include erratic rainfall, high temperature, droughts and floods. Climatic and non-climatic stressors interact to affect agricultural practices and related livelihoods. The study identified various adaptation measures including extensification and intensification of agriculture, temporary migration, planting of drought resistant varieties, irrigation, and livelihood diversification. We show that many coping measures (e.g. livelihood diversifications activities such as selling of firewood and charcoal production) and adaptation responses (including intensification, extensification and irrigation) currently deliver maladaptive outcomes, resulting in lock-ins that could exacerbate future climate vulnerabilities. The paper contributes to the growing literature on adaptation and climate risk management by providing empirical evidence showing how coping and adaptations measures can deliver maladaptive outcomes in vulnerable communities.

Reservoir catchments in Ghana have undergone significant changes in recent years with major implications for socio-economic development and local livelihoods. We studied land use and land cover changes and their impacts on livelihoods in the Owabi reservoir catchment from 1970 to 2014 using Landsat, ERDAS Imagine and Arc Geographic Information System (ArcGIS 10.2) software supplemented with participatory approaches including focus group discussions, key informant interviews and questionnaire surveys with 400 households. Our results showed that, since 1970, 24.6% of high-density forests and 15.8% of sparse forests have disappeared, while the built-up area has increased from 9.8% to 56.6%. Additionally, the proportion of bare soil (areas that do not have vegetation cover due to forest clearing and other anthropogenic activities) has increased, while the areas of waterbodies have declined. We identified urbanisation and lack of community involvement in catchment management as the key factors driving the land cover changes that have adversely affected the livelihoods of the local fringe communities. This study highlights the threats from urbanisation to land cover changes and identifies the key drivers of land use change. For effective and sustainable management of natural resources, the local communities should be more actively involved in the decision-making process regarding the management of their individual catchments.

The vulnerability of social-ecological systems in sub-Saharan Africa (SSA) to climate variability and change means that there is an urgent need to better integrate weather and climate information into societal decision-making processes. Long-term climate adaptation in these regions has received increasing attention, with recent initiatives aiming to increase resilience to climate change at timescales of years to decades. Less focus has been given to weather and short-term climate information. However, users are principally interested in shorter timescales (hours to seasons) where actions can immediately reduce the impacts of severe weather events. Focusing on the priority sectors of agriculture and food security, water and disaster management, this paper uses a systematic literature review approach to analyse 61 empirical case studies drawn from academic literature and projects across SSA. We identify the main users of climate services and outline current practices and reported benefits. Barriers that impede the delivery and uptake of climate services are identified and potential strategies for overcoming them outlined based on the reporting of successful practices. Our findings show that greater capacity building of personnel working for National Meteorological and Hydrological Services and Agricultural Extension staff and reinforcing and sustaining collaboration between different stakeholders (climate scientists, hydrologists, extension workers, farmers and other user groups), are essential factors for improving the uptake and utility of weather and climate services to enhance resilience to climate shocks in SSA.
