The Meki catchment in the Central Rift Valley basin of Ethiopia is currently experiencing irrigation expansion and water scarcity challenges. The objective of this study is to understand the basin's current and future water availability for agricultural intensification. This was done by simulating scenarios through an integrated SWAT-MODFLOW model to assess the water balance. The scenarios were co-developed with communities who expressed their aspirations for agricultural intensification in conjunction with projected climate change. The results show that with the present land use and climate, the catchment is already water stressed and communities cannot meet their irrigation water demand, particularly in the first irrigation season (October–January). However, in the second irrigation season (February–May) water resource availability is better and increasing irrigated area by 50% from the present extent is possible. With a climate change scenario that favours more rainfall and shallow groundwater use, agricultural intensification is feasible to some extent. [ABSTRACT FROM AUTHOR]

The main focus of this article is to explore whether access to selected agricultural water management (AWM) technologies has led to significant reduction in poverty and, if they did so, to identify which technologies had higher impacts. In measuring impact we estimated the average treatment effect for the treated on crop income and measured the differences in consumption expenditures per adult equivalent of those with access and without access using matched data. The estimated average treatment effect was significant and amounted to USD 82 per season. Moreover, there was 24 less poverty incidence among users of AWM technologies compared to nonusers. All technologies were found to have significant poverty reducing impacts with micro dams, deep wells, river diversions, and ponds leading to 37%, 26%, 11%, and 9% reduction in poverty incidence compared to rainfed system. Finally, our study identified the most important correlates of poverty on the basis this we made the policy recommendations to build assets (AWM technologies, livestock, etc); to enhance human resource development and improve the functioning of labor markets for enhanced impact of AWM technologies on poverty.

Irrigation development has been identified as an important tool to stimulate economic growth and rural development, and is considered as a cornerstone of food security and poverty reduction in Ethiopia. While a lot of effort is being exerted towards irrigation development, little attempt is being made to quantify the contribution of irrigation to national income. This study is an attempt in that direction by quantifying the actual and expected contribution of irrigation to the Ethiopian national economy for the 2005/2006 and 2009/2010 cropping seasons using the adjusted net gross margin analysis. Our results show that irrigation generates an average income of approximately US$323/hectare (ha) under smallholder-managed irrigation systems compared to an average income of US$147/ha for rainfed systems. This indicates that, after accounting for annual investment replacement cost, the adjusted gross margin from irrigation is 219.7% higher than the gross margin from rainfed agriculture. The gross margin from medium- and large-scale systems was calculated to be US$400/ ha and US$1,308/ha, respectively. Based on our calculations, irrigation contributed approximately 5.7 and 2.5% to agricultural Gross Domestic Product (GDP) and the overall GDP, respectively, during the 2005/2006 cropping season. By the year 2009/2010, the contribution of irrigation to agricultural GDP and overall GDP is estimated to be approximately 9 and 3.7%, respectively. After relaxing some of the underlying assumptions, the future contribution of irrigation to agricultural GDP rises to approximately 12% while the contribution to overall GDP will be approximately 4%. To realize these outcomes, besides the obvious task of developing the planned irrigation infrastructure, there is a need to: i) improve the provision of agricultural inputs including high-value crops, ii) improve the performance of the agricultural extension system to support irrigation to enhance efficiency and productivity, iii) improve market access conditions and marketing infrastructure, and iv) improve the management of schemes to increase efficiency at all levels. Additional policy implications for cost recovery and sustainability of irrigation investment are drawn. [ABSTRACT FROM AUTHOR]

Land degradation poses a serious problem for the livelihoods of rural producers. Furthermore, there is rarely enough private investment taking place to commensurate the scale of the problem. This article examines the role of tenure insecurity, resource poverty, risk and time preferences, and community-led land conservation on differentiated patterns of household investment in land conservation in northern Ethiopia. We control for biophysical, household characteristics, market access conditions, and village level factors. Investments in soil bunds and stone terraces are specifically studied so as to capture the link between these various factors and the durability of conservation investments. We introduce the distinction between the determinants of the decision to invest and how much to invest in conservation. Regression results show that publicly led conservation programs seem to significantly stimulate private investment. A host of plot-level variables and household perceptions of returns on conservation investments, expressed in terms of perceived improvements in land quality and increased crop yields, were found to be critical to the decision to invest and intensify soil conservation. The evidence on the significance of households' attitudes toward risk aversion suggests the important role of risk and the household's risk-bearing capacity in the decision to intensify conservation measures. At the same time, tenure security indicators and households' resource endowments (resource poverty) had weaker effects in increasing willingness to invest and the level of investment made. The policy implications of these results point to the importance of agricultural research and extension efforts that target technologies which reduce household risk and poverty while enabling sustainable investments in conservation measures by individual households.

This study undertook an assessment and gap analysis of the institutional arrangements for improved land and water management in the Tana and Beles Sub-basins highlands of the Blue Nile Basin. We explored the mandates and design features of the major land- and water-related institutional arrangements. Focus group discussions, key informant interviews, and a literature review were used in the analysis. The results of our work reveal that a lot of progress has been made in creating an institutional framework for improved land and water management and the policies and laws hitherto developed reflect global policy changes consistent with the widespread adoption of the integrated water resources management (IWRM) principles. There are also cases where informal institutions replace formal institutions. Judged by their enforcement, the water resources management, pollution control standards, and regulations and land use rights are not enacted effectively because of poor enforcement capacity. Overall there is a tendency to focus on command-and-control type policies. There is a need to strengthen traditional institutions by drawing lessons from their strengths and establish the legitimacy of these institutions. There is also a need to improve formal policy design, developing policies with specific objectives, goals, targets, and overall institutional changes and resources through active adaptive management to maximize the level and effectiveness of institutional learning. Finally, more focus needs to be given to incentive-based policies through increased use of positive incentives and more emphasis needs to be given to self-enforcement rather than third-party enforcement.

Prevalence of malnutrition was assessed in 213 adolescent girls aged 10 to 19 in Tigray, Northern Ethiopia. The mean age, height-for-age (HAZ), weight-for-age (WAZ), body mass index (BMI), and BMI Z scores were 14 y, -1.45, -1.87, 15.7 and -2.20, respectively. More than 35% of the households reported girls did more work than boys. Most households (74%) reported food shortage during the summer. More than 80% of the households had no latrine and their source of water was river and/or unprotected wells (96%). No access to micronutrient supplementation or de-worming was reported for adolescents; however, 98% had access to health facilities for illness and immunizations. Stunting and under weight were 26.3 and 44.1% respectively. On the basis of their BMI, younger adolescents were more undernourished than older adolescents (p <0.0001). Reduction in number and quality of meals, and heavy involvement in works like laundry, cattle herding and long distance shopping were the main factors significantly associated with stunting. Differential treatment in food availability, reduction in the quality of meals and heavy workload were associated with under weight in adolescent girls. Participatory community level interventions to address girls' workloads and gender role expectations, environmental sanitation, and household food shortages are recommended. [ABSTRACT FROM AUTHOR]

• We investigate the demand supply side constraints of credit facing smallholders in developing countries using survey data and econometric models. • Against several past studies and policy discourse linking rural credit to suppl-side factors, we found that demand-side factors such as risk-aversion behavior are equally important. • Our results suggest that women are more likely to be credit constrained (from both the supply and demand sides) than men in both study countries. • We suggest on addressing both supply- and demand-side credit constraints, and gender-sensitive policies to improve women's access to credit. Credit constraint is often considered as one of the key barriers to the adoption of modern agricultural technologies and low agricultural productivity in low- and middle-income countries. Past research and much of the policy discourse associate agricultural credit constraints with supply-side factors, such as limited access to credit sources or high costs of borrowing. However, demand-side factors, such as risk-aversion and financial illiteracy among borrowers could also affect credit-rationing of smallholder agricultural households. This study investigates the nature of credit constraints, factors affecting credit constraint status, and the effects of credit constraints on adoption and intensity of use of three modern agricultural technologies – small-scale irrigation, chemical fertilizer, and improved seeds. The paper also assesses whether credit constraints are gender-differentiated. Primary survey data were collected from sample farmers in Ethiopia and Tanzania, and Tobit and two-step hurdle econometric models were used to analyze these data. Results show that demand-side credit constraints are as important as supply-side factors in conditioning smallholders' access to credit in both countries. We also find that credit is a binding constraint for the decision to adopt technologies and input use intensity in Tanzania but not statistically significant in Ethiopia. Results suggest that women are more likely to be credit constrained (from both the supply and demand sides) than men in both study countries. Based on these findings, we suggest that policies should focus on addressing both supply- and demand-side credit constraints to credit access, including through targeted interventions to reduce risk, such as crop insurance, and to strengthen the gender sensitivity of credit policies.

Water governance demands multi-sector participation beyond the state; and, appropriate laws, policies, regulations, and institutions need to be developed and put in place for sustainable use of water resources. A good water policy, a critical and integral instrument of water governance, guides water use schemes and ensures equitable water distribution among users. The Ethiopian Central Rift Valley (CRV) is rich in water resources, but these water resources are currently under severe strain owing to an imbalance in human-water interactions. This study examined the state of water resources governance framework, policy coherence, actors' engagement and transparency, accountability, and participation in irrigation water supply in the CRV of Ethiopia. Key informant interviews (KII), focused group discussions, and document reviews were used to gather data for the study. The NVivo 11 program was used to organize, code, and analyze the data. The results revealed that water resources governance practices such as water allocation and apportionment, water resources protection, and conservation activities were inappropriately exercised. Water resources management policy mechanisms were not fully put in place. Lack of coherence in water policy implementation, absence of clear roles and responsibilities of stakeholders, absence of transparency and accountability in irrigation water service delivery, and lack of meaningful participation of key actors in water governance decision-making were observed. As a result, over-abstraction, deterioration of buffer zone areas, and chemical erosion from surrounding farming are attributed to the reduction in water volume and quality in the CRV. These challenges have influenced aquatic ecosystem services and threaten the livelihoods of the surrounding communities. Hence, reforms relating to policy coherence and enforcement, stakeholder engagement, water distribution strategies, and the implementation of water governance principles must be given adequate emphasis., (© 2024.

Background: Institutions can play a key role in coordinating how natural resources are effectively managed and used without over-exploitation. Institutions are laws, policies, and organizational arrangements that permit, forbid or regulate human action. This study aimed to look into the roles of formal and informal institutions, and their interactions in water resources governance in the Central Rift Valley (CRV), Ethiopia., Methods: Key informant interviews, focus group discussions, and secondary data sources were employed to collect relevant data., Results: The result of the study indicated that the influence of informal institutions on formal institutions or vice versa was insignificant, and unable to change the actions of water users in the CRV. Other limitations observed in water resources governance in the CRV include a lack of actors' clear roles and responsibilities, absence of meaningful decentralization, limited engagement of key actors in policy development, lack of synergy between the institutions, and absence of enforcement mechanisms., Conclusion: Considering the local contexts and community's traditional knowledge of water governance in water-related policy, rules, and regulations, and enhancing the capacity of local-level institutions, strong interplay among all institutions involved in water governance, and meaningful actors' engagement were recommended to advance the role of institutions in water resources governance in the CRV and in the country. Hence, a mechanism that enables to harmonize formal and informal institutions in water management system can enhance the governance of water resources in the study area and elsewhere in the country., Competing Interests: No competing interests were disclosed., (Copyright: © 2024 Jibat E et al.)
