The damaging effects of changing climate on farm-household food security are steadily increasing in sub-Saharan Africa. Adaptation strategies are important for agrarian households to reduce the adverse effects on their food security. This study employed multivariate probit and endogenous switching regression models to analyze the determinants of farm households' choice of climate-change adaptation strategies, such as the cultivation of early maturing crops, early planting, growing drought-tolerant maize varieties, using precautionary savings, practicing income diversification, and sale of assets, and their effects on household food security in Tanzania. Information on expected rainfall and temperatures, early warning systems, previous droughts, delays in the onset of the rainy season, sex and age of the farmer, educational level, farming experience, family size, total farmland holding, number of livestock owned, contact with extension agents, and access to credit services were all found to influence decisions by farm households to use strategies of adaptation to climate change. Overall, the adaptation of farm households to climate change increased their food security status. An analysis of "adapter" and "non-adapter" farm households showed that the effect of adaptation on food security was smaller for households that adapted than for households that did not. Thus, we recommend that further effective adaptation strategies such as planting drought-resistant crops, changing planting dates, planting early maturing crops, and practicing income diversification be developed and used, particularly for the most vulnerable farm households, to mitigate the adverse impacts of climate change on their food security.

This paper analyses the impact of climate-smart agriculture (CSA) technologies on household dietary diversity and food insufficiency as indicators of food and nutrition security in Kenya. Using a combination of Propensity Score Matching and endogenous treatment effect approaches, we found that adoption of stress-tolerant varieties of several crops (such as bean, pigeon pea, cowpea, maize and sorghum) improved household dietary diversity score by 40% and reduced food insufficiency by 75%. Adoption of improved and resilient livestock breeds (including Red Maasai sheep and Galla goats) improved household dietary diversity by 38% while reducing household food insufficiency by 90%. We also found that stress-tolerant crop varieties were more effective in improving food security outcomes among households with large landholdings and with more educated and younger to middle-age heads. Effects of resilient livestock breeds on household food security were much stronger for households with large landholdings and with young and/or much older heads that have low levels of education. Given the large, demonstrated benefits from the use of the CSA technologies, policies and programs aimed at their promotion should apply appropriate targeting to ensure wider uptake of the technologies and maximum returns on investment.

The increasing complexity of food insecurity, malnutrition, and chronic poverty faced by Sub-Saharan Africa warrants urgent categorisation and tracking of household food security along both temporal and spatial dimensions. This will help to effectively target, monitor and evaluate population-level programs and specific interventions aimed at addressing food insecurity. Traditional longitudinal analysis does not address the dynamics of inter- and intrahousehold heterogeneities within the seasonal and spatial context of household-level food security. This study is the first to overcome such limitations by adopting a multi-group piecewise latent growth curve model in the analysis of the food security situation in a statistically representative sample of 601 households involved in subsistence and cut-flower commercial agriculture, around Lake Naivasha. We considered food security as a latent concept, which manifests as food security outcomes in our primary longitudinal dataset from March 2018 to January 2019. Our analysis highlights the temporal and spatial dynamics of food security and advances new evidence on inter- and intrahousehold heterogeneities in food security across different seasons for the subsistence and commercial farming clusters. These heterogeneities were demonstrated primarily during the hunger season from March to June, and persisted in both the clusters and across months, albeit with different intensities. Moreover, our results indicate the importance of commercial agriculture in achieving food security in the hunger season. Our study suggests the need of a multidisciplinary approach to food security and the introduction of well-coordinated interventions for the development of subsistence and commercial agriculture considering the seasonal and cluster-level specificities.

COVID-19 undermines food security both directly, by disrupting food systems, and indirectly, through the impacts of lockdowns on household incomes and physical access to food. COVID-19 and responses to the pandemic could undermine food production, processing and marketing, but the most concerning impacts are on the demand-side – economic and physical access to food. This paper identifies three complementary frameworks that can contribute to understanding these effects, which are expected to persist into the post-pandemic phase, after lockdowns are lifted. FAO's 'four pillars'– availability, access, stability and utilisation – and the 'food systems' approach both provide holistic frameworks for analysing food security. Sen's 'entitlement' approach is useful for disaggregating demand-side effects on household production-, labour-, trade- and transfer-based entitlements to food. Drawing on the strengths of each of these frameworks can enhance the understanding of the pandemic's impacts on food security, while also pinpointing areas for governments and other actors to intervene in the food system, to protect the food security of households left vulnerable by COVID-19 and public responses.

This article conducts a systematic literature review to analyze and consolidate empirical and/or theoretical evidence that shows the importance of wild foods for household food security in tropical forest areas. For these territories, forest plants, fungi and animals are not only important as a source of food, but also for generating community income. The main challenges related to wild foods are the negative effects on protection of species and the risks to human health when this food is consumed without testing for safety and nutrition. Once these challenges are met, wild foods can serve to bolster food security which can help to sustain territories in tropical forests. [ABSTRACT FROM AUTHOR]

Agriculture is the predominant livelihood for 70 % of the population living in rural India, and food expenses occupy a major proportion of their household budget. Rural household diets suggest that agricultural growth has contributed to increasing calorie intake with very minimal effect on the intake of protein and micronutrients. This in turn causes weak positive impact of agriculture on household dietary diversity and nutrient adequacy. Given the prevalence of high levels of under-nutrition and a large population dependent on agriculture, recent thinking globally on leveraging agriculture for nutrition security has encouraged the agricultural sector to realign its focus not only to increase food production, but also to address under-nutrition. Against this background, an exploratory study was conducted in resource poor villages of Wardha and Koraput districts in the states of Maharashtra and Odisha in India, to investigate how location-specific Farming System for Nutrition (FSN) interventions can potentially improve the diversity of household diets and nutrition outcomes. A detailed baseline study was undertaken to identify the existing disconnect between agriculture-nutrition linkages. In the study locations, the proportion of all forms of under-nutrition, vitamin A deficiency and iron-deficiency anaemia among children <5-years of age appeared unacceptably high. A high prevalence rate of chronic energy deficient (CED) women and anaemic pregnant women was also observed. A higher risk of under-nutrition and micronutrient deficiency among household members was associated with substandard living conditions of the surveyed households. Cropping systems in Wardha were primarily dominated by rain-fed commercial cash crops while rain-fed subsistence farming predominated in Koraput. Households in both study locations were found to have cereal-dominated diets with average daily consumption of pulses, fruits and vegetables, and milk and milk products well below the recommended daily intake level, indicating low dietary diversity. In both Wardha and Koraput, CED in adults (>18 years) significantly increased as the dietary diversity score (DDS) decreased from high to low. In Koraput, the prevalence rate of anaemia in adolescent girls and women significantly increased, as the DDS decreased. We conclude that food and diets lacking diversity and without nutrition-sensitive farming systems (either commercial- or subsistence-based) may not be appropriate to improve household nutrition and health status. Our findings provide a basis for structuring integrated agriculture-nutrition programmes or a FSN approach to diversifying household food and diets, for improving nutrition and health in India.

The Ati Negrito people, a recently settled hunter-gatherer indigenous group in the Philippines, are faced once more with the challenge of adapting to new settlements and gradually declining areas of prime food sources. The research is a documentation of uses and importance of wild edible plants the group collects and consumes as a transitioning hunter-gatherer community. Interviews were conducted with 44 female key informants representing 40 households. A total of 69 wild edible plant taxa in 31 plant families were recorded. Informant consensus revealed that many wild food plants are prioritized for their caloric content and dietary structure to complement oftentimes monotonous diets. Some of the recorded edibles were found to be non-native weedy introductions, signs of mechanisms for coping with environmental and socio-cultural changes. Preferences for certain wild edible plants also revealed that non-food factors underlay food choices. Significant factors that influence food knowledge and selection appeared to be household income, acculturation and past experiences of food scarcity. Further studies, however, have yet to provide concrete evidence that there is erosion of traditional knowledge. Regardless, determining informant confidence in selecting wild food plants has emphasized that preferences are decided based on socio-economic, cultural and ecological conditions.

The level of diversity in household diets is an indirect measure of diet quality and the extent to which nutritional needs of households are being met. There is also a positive relationship between dietary diversity and the three pillars of food security, viz., availability, access and utilization. In the light of these statements, the paper reports on the patterns of food consumption and dietary diversity in 12 selected villages of eastern India with a view to understanding the heterogeneity in food habits, quality of diet intake and the socio-economic and demographic determinants of the dietary diversity in the region. There was significant disparity across the villages in terms of budgetary shares and intake levels of different food items. The level of heterogeneity in food intake was also reflected in the estimates of dietary diversity across villages. Multiple regression analysis on the determinants of dietary diversity showed that larger households with better-educated male heads and higher purchasing power fared well on dietary diversity scores. Access to the Public Distribution System (PDS) also contributed to enhancement of dietary diversity through an indirect route, as PDS beneficiaries are better able to afford diverse food items. In contrast, low social status in the form of affiliation to scheduled castes/scheduled tribes (SC/ST) diminished diversity scores. From a policy perspective, it is therefore important to focus interventions on improving dietary diversity and nutrition security with proper understanding of the socio-economic setting of the target area and its population.

Many rural households in the developing world are subject to chronic seasonal food insecurity. Often cited among coping strategies is foraging for wild foods. This study was to understand the role of wild food in household food security in Timor-Leste. Information on wild food use comes from three sources: a) a longitudinal study of food consumption among 14 subsistence farmer households across four districts in 2006-2007; b) a survey in 2011 of 1,800 farmer households across all 13 districts in Timor-Leste; and c) a survey of 64 households from eight community seed groups in three districts in 2013. The consumption of wild food fluctuated widely across the year with consumption much reduced in the wet season (December - April) compared to the dry season (May - November). Wild food use in a normal year - 2006-2007 and a food-deficit year - 2011, characterized by a severe hungry season, were compared. In the normal year the maize grain store was exhausted in 50 % of households (expressed as cumulative percentage of 'at risk' households) during the month of August and the percent of households consuming wild food was 9.2 %. By contrast in the food deficit year, maize grain stores were typically exhausted 2 months earlier than in a normal year, and 50 % of all interviewed households were foraging for wild food by May in four districts. Clearly in the food deficit season wild food foraging was dramatically increased compared to a normal year, particularly by poor at-risk households. The early depletion of grains store stocks under food insecurity resulted in greater coincidence of the period of wild food foraging with the hungry season than in a normal year. In two surveys there were clear differences between districts in the extent of wild food foraging. The most widely eaten wild plant foods in Timor-Leste are lesser yam ( Dioscorea esculenta considered wild in Timor-Leste) followed by elephant's foot yam ( Amorphophallus paeoniifolius) and bitter bean ( Phaseolus lunatus). Looking to the future in Timor-Leste, the wild food resource will continue to provide an important food buffer in deficit years especially to poor at-risk households, increasing their resilience and reducing their vulnerability.

This paper aimed to investigate the determinants of water security in an irrigation scheme, and how this water security level subsequently affects the farmer's household food security level. Water security refers to access by the irrigating households to sufficient and reliable water to meet the agricultural needs and their ability to assert the water rights against other parties. A random sample of 185 irrigating households was interviewed in Tugela Ferry Irrigation Scheme in Mzinyathi District, South Africa. Data were analysed using principal component analysis and ordinary least squares. The empirical results indicated that factors such as farmer's age, off-farm income, farmer association membership, use of pumps, location on the upper-end of the canal and training increase household water security. Conversely, factors such as occurrence of conflicts and location at the tail-end of the canal were found to decrease household water security. This study highlights the importance of strengthening farmer organisational capacity and local institutions for enhancing the water security status of farmers in smallholder irrigation schemes. The results also indicated that perceived water security has a positive impact on household food consumption per adult equivalent. Therefore, for better impact on household food security, the study recommends that priority should be placed in ensuring household water security, not just investing in the physical irrigation scheme and irrigation participation. The human and social dimensions need to receive priority. Training farmers in collective water governance and water conservation techniques to improve water-use efficiency as well as introducing motorised pumps would take irrigators a long way in enhancing their water security.

Wild vegetables (WV) are an important source of food in the maize based subsistence farming sector of rural South Africa. Their main role is as relish as they are used as an accompaniment for staple cereal based diets. They are generally reported to be rich in micronutrients. Although they may be consumed in small quantities, they influence the intake of cereal staples, manage hunger and play a central role in household food security for the poorer rural groups. Mixing several WV species in one meal contributes to dietary diversity in terms of more vegetable types as well as in terms of choice of relish. For some very poor families WV are substitutes for some food crops. The seasonal occurrence of these vegetables leaves many families without a food source during the off-season. Wild vegetables increase agro-biodiversity at the household level. This agro-biodiversity helps in buffering against the accumulation and multiplication of pests and diseases and provides important cover for the soil. Further research on agronomic, social and economic dimensions is required to understand the roles of WV in subsistence farming systems in South Africa. [ABSTRACT FROM AUTHOR]

Timor-Leste is among the world's youngest and poorest countries. It suffers from seasonal food insecurity and has the third-highest stunting rate globally. Previously inadequately documented, this paper summarises recent advances in understanding household food security in Timor-Leste and the multifaceted approaches being used to overcome it. Information comes from the extensive annual surveys of the Seeds of Life (SoL) program in Timor-Leste. The hungry season prior to maize and rice harvests is the key issue in household food security in Timor-Leste. Farm households cope with the problem through crop diversification with tubers playing a lead role as grain stocks dwindle. Foraging for wild food resources, selling animals and other assets, and social networks are other coping strategies. To address seasonal food insecurity, the government has focused on rice importation and the improvement of agricultural productivity within a multi-dimensional program. Information on storage by households of the key staple, maize, indicates an improving trend in food security at the household level from 2006/2007 to 2010/2011 through a significant reduction in the percentage of 'at risk' households-those who grow insufficient maize for storage during the year. The current emphasis on the widespread dissemination of the new high-yielding SoL cultivars has the potential to augment these improving trends. Nevertheless this picture remains vulnerable to weather shocks-such as drought-which are anticipated to increase with climate change and it is important to build further resilience into the agricultural systems of Timor-Leste.
