Between 2017 and 2021, the Bureau for Humanitarian Assistance (BHA) of the United States Agency for International Development supported public works in the areas of watershed rehabilitation and small-scale irrigation under Ethiopia’s Productive Safety Net Program (PSNP). The investments aimed to improve food security and nutrition and to increase the resilience capacities of households through improved natural resource systems and asset development. However, there is little evidence about how these water-related investments supported household food security, nutritional outcomes, and resilience. This study used a mixed-methods approach to fill some of these knowledge gaps. Econometric results show that households in BHA intervention areas had smaller food gaps, and this association is statistically significant. Similarly, households that adopted small-scale irrigation and water harvesting techniques on their own plots show significantly better nutritional outcomes than those that did not. The results further suggest that in general the households in BHA areas are more resilient than those in non-BHA woredas. However, higher resilience capacities are associated with agricultural water management on own plots rather than with public works in communal lands. Thus, if household security, nutrition and resilience are key goals of program interventions, then programs need to grow intentionality in developing assets, and particularly irrigation.

The evidence on the potential for agricultural interventions to contribute to improved nutrition has grown considerably over the past decade (Ruel et al., 2018). Numerous studies have explored both positive and negative effects of agriculture on nutrition and health (Ruel and Alderman, 2013; Herforth and Harris, 2014; Masset et al., 2012; Hoddinott, 2012). However, as an important and growing component of agriculture, smallscale irrigation has not yet been given the attention it deserves. The Innovation Laboratory for Small Scale Irrigation (ILSSI) set out, among others, to fill the evidence gap on irrigation-nutrition linkages. Domènech (2015) describes several potential pathways through which irrigation can influence food security, nutrition, and health outcomes, including 1) a production pathway, 2) an income pathway, 3) a water supply pathway, and 4) a women’s empowerment pathway. To illustrate these pathways, we adapted the agriculturenutrition framework of Herforth and Harris (2014) to include irrigation (Figure 1), while also noting a fifth, negative pathway that links irrigation to water pollution and disease via the application of fertilizers and pesticides and via supporting vector-borne diseases, such as malaria or schistosomiasis, respectively (Passarelli et al., 2018).

Credit constraint is considered by many as one of the key barriers to adoption of modern agricultural technologies, such as chemical fertilizer, improved seeds, and irrigation technologies, among smallholders. Past research and much policy discourse associates 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, as well as high transaction costs, can also play important roles in credit-rationing for smallholders. Using primary survey data from Ethiopia and Tanzania, this study examines the nature of credit constraints facing smallholders and the factors that affect credit constraints. In addition, we assess whether credit constraints are gender-differentiated. Results show that demand-side credit constraints are at least as important as supply-side factors in both countries. Women are more likely to be credit constrained (from both the supply and demand sides) than men. Based on these findings, we suggest that policies should focus on addressing both supply- and demand-side credit constraints, including through targeted interventions to reduce risk, such as crop insurance and gender-sensitive policies to improve women’s access to credit.

The goal of this study is to assess the potential of game-based experiential learning in raising awareness and stimulating discussions about groundwater resource systems, the social dilemma in groundwater management, and the need for institutional arrangements (rules) governing this shared resource, as well as whether such awareness and community discussions lead to actual change in groundwater governance in Ethiopia. Groundwater management is highly complex, with many users sharing the same resource often without realizing their interconnectedness. Behavioral experiments (games) that simulate real-life common-pool resource use have shown promise as an experiential learning tool for improving resource governance. This study pilots an experiential learning intervention in Ethiopia using a groundwater game to help raise awareness of groundwater over-extraction and improve understanding of the importance of collective action in governance. The Meki River catchment in rural Ethiopia is a unique context where small-scale irrigation is expanding, but over extraction and competition over groundwater have not yet reached alarming levels. The groundwater game, adapted from Meinzen-Dick et al. (2016 and 2018), was played in 15 villages, accompanied by community-wide debriefing discussions in each village after the game to reflect on the process and lessons learned, and to stimulate discussions around groundwater governance. We carried out participant surveys to capture individual mental models regarding groundwater use and management, as well as any immediate learning effects. Focus group discussions were held in each village prior to the intervention to establish a baseline and again six months after the intervention to assess possible lasting effects. The findings indicate cognitive, normative and relational learning, including increased understanding of groundwater dynamics (such as the joint effect of diverse water uses and users), the importance of collective action in resource management, and the benefits of communication. We find gendered differences in decision-making about resource extraction in the game and evolvement of group-level resource management across no-communication, communication, and rule-making rounds of the game. We discuss community-wide learning and institutions-building, and considerations for future intervention designs. We recommend embedding experiential learning, facilitated by local extension officers or other community engagement practitioners, in intervention packages that include both technical assistance on water-conserving technologies and management approaches and support in building communities’ institutional capacity.

We analyze the linkages between irrigation and nutrition using data from irrigators and non-irrigators in Northern Ghana. The results show that (i) there is a modest difference in the overall household dietary diversity score between irrigators and non-irrigators, (ii) there are significant differences in the consumption of animal source foods between irrigators and non-irrigators, (iii) there are significant differences in the consumption of fruits and vegetables as well as sugar and honey between irrigators and non-irrigators, and (iv) the sources of food consumption differ between irrigators and non-irrigators. The analysis shows strong association between households’ nutritional status and their access to irrigation, with evidences suggesting that the irrigation-nutrition linkages play out both through the income and production pathways in Northern Ghana.

Land degradation is a pressing global challenge, with three billion people residing in degraded landscapes. The global cost of land degradation is estimated to be about $300 billion per year, with Africa south of the Sahara accounting for 26 percent of the total global costs due to land-use and land-cover changes. In Ethiopia, it is estimated that more than 85 percent of land is moderately to severely degraded due to changes in land use and cover, costing the country an estimated US$4.3 billion annually. In order to halt further degradation and support essential restoration through sustainable land management (SLM) and related investments, the Water and Land Resource Center (WLRC) and its consortium of development partners established six learning watersheds in Central and North-Western Ethiopia with the ultimate goal of improving water security and crop and livestock productivity.

Climate change forecasts for Ethiopia predict higher temperature and rainfall and increased variability in rainfall with periodic severe droughts and floods. The increased weather variability threatens the extent of Ethiopia’s agricultural transformation unless it is supported with improved agricultural water management such as irrigation to make smallholder farming resilient to adverse weather events. This study analyzes the role of irrigation on agricultural transformation in Ethiopia by systematically comparing households with irrigated and non-irrigated plots on key agricultural transformation and welfare indictors (i.e., intensification, commercialization, and consumption expenditures). The study used a representative data from the four main agriculturally important regions of the country and employed an endogenous switching regression approach that addresses potential biases from placement of irrigation schemes and the self-selection of farmers to adopt irrigation on their plots. This approach allows for counterfactual analysis on the effect of irrigation if it is adopted on plots or in households without current irrigation as well as the counterfactual realizations of outcome variables if irrigated plots were not irrigated or irrigating households were relying only on rainfed agriculture. The main results show a positive and significant effects of irrigation on intensification, commercialization, and household welfare. Specifically, the results show that farm households with irrigated plots (i) use more fertilizer and agrochemicals, (ii) sell sizable shares of their harvest, and (iii) spend more on food and non-food expenditures. The counterfactual analysis on what would have been the effect of irrigation on currently non-irrigated plots indicate a stronger result across our outcome indicators which further suggest the importance of expanding irrigation in accelerating agricultural transformation and welfare improvement in Ethiopia.

Several factors contribute to the low level of improved variety use in Ethiopia. Among those, on the supply side, is the limited availability of seed in the volumes, quality, and timeliness required by farmers, which is partly a result of limited public and private investment in the sector. Beginning in 2011, the Government of Ethiopia introduced a novel experiment-the Direct Seed Marketing (DSM) approach-to reduce some of the centralized, state-run attributes of the country’s seed market and rationalize the use of public resources. DSM was designed to incentivize private and public seed producers to sell seed directly to farmers rather than through the state apparatus. This study is the first quantitative evaluation of DSM’s impact on indicators of a healthy seed system: access to quality seeds, on-farm productivity, and market participation of smallholders. Using a quasi-experimental difference-in-differences approach, the study finds that DSM led to a 26 percent increase in maize yields and a 5 percent increase in the share of maize harvest sold. DSM also led to improvements in seed availability for all three of Ethiopia’s major cereals: maize, wheat, and teff. However, DSM’s effects on yields and share of harvest sold are not statistically significant for wheat and teff. These crop-specific differences in performance are likely explainable by biological differences between hybrid maize and openly pollinated varieties of wheat and teff that incentivize private sector participation in maize seed markets over wheat and teff seed markets. These differences demand different policies and perhaps even institutional approaches to accelerating adoption between hybrids and OPVs.

Small-scale irrigation (SSI) provides great benefits to farmers in terms of increased yields and profits, better food and nutrition security and greater resilience to climate shocks. Ethiopia has high potential for expanding SSI and has invested considerably in this area in recent years. Despite these investments, several challenges to further expansion of irrigation technologies remain. Different stakeholders in the country play important roles in overcoming these barriers to further scale technologies for SSI. This paper explores institutional arrangements for the diffusion of small-scale irrigation technologies by mapping the landscape of key actors involved, their interconnections, and their influence. This paper draws on an analysis of stakeholder data collected through two participatory workshops in Ethiopia, one at the national level and one at the Oromia regional level, using the Net-Map approach. Results show the dominance of government actors in the diffusion of SSI at both the national and regional levels, while most private sector and NGO actors remain in the periphery. Participants in both workshops highlighted the need for increased financing services to support the adoption of SSI and measures aimed at increasing the supply of high-quality irrigation equipment, such as modern water lifting technologies. One notable difference between the national and regional results was that at the regional level, farmers, and to some extent traders and input suppliers, were considered to be more influential in the diffusion of irrigation technologies, while they were considered marginal actors at the national level.

The El Nino Southern Oscillation (ENSO) weather event of 2015/16 caused severe drought conditions in northern and central Ethiopia affecting the welfare of millions of farmers in late 2015 and early 2016. Using nationally representative panel data collected in 2012 and 2016 and recent advances in the difference-indifferences literature, this paper explores the effects of the 2015/16 drought and the potential role of irrigation in reducing the adverse effects of the drought. We find that the drought caused, on average, a 37 percent reduction in net annual crop income, an 8 percent decline in area cultivated, a 3 percent decline in household dietary diversity score, and a 10 percent decline in the share of harvest sold for rainfed farmers. On the other hand, irrigating farmers affected by the drought managed to increase their daily expenditures by 72 percent of their average daily food expenditure in the pre-drought period, and maintained their net crop income, size of cultivated land, household dietary diversity, and share of harvest sold to the market. Overall, while rainfed agricultural producers suffered sharp declines in welfare, those farmers with access to irrigation maintained their economic status. The results suggest that irrigation protected farmers from the adverse effects of the 2015/16 ENSO event and given increasing climate variability in Ethiopia, the government should intensify its investment and support to irrigation development in the country.
