Water management strategies and allocation policies that support agricultural intensification across agro-ecological zones and hydrologic basins are required for building resilient agrarian communities in sub-Saharan Africa.We provide an overview of the research and investments needed to enhance agriculture in the region, with a focus on technology and institutions, while describing opportunities for improving rainfed crop production.We discuss a range of water management practices in three river basins that were part of the Challenge Program onWater and Food research on Basin Development Challenges from 2009 to 2013. Our main message is that technical and institutional innovations in water management are required for creating and sustaining resilient agrarian communities in sub-Saharan Africa. Such innovations are best designed and implemented in consultations involving researchers, households, investors, and other participants with a management or regulatory responsibility. It is in this collaborative spirit that we introduce this Special Issue of Water Resources and Rural Development, in which several authors present results of studies on agricultural water management in the region, with recommendations for better planning and implementation of interventions to benefit smallholder farmers.

Small-scale irrigation is playing an important role in adapting to climate change, achieving food security, and improving household incomes. The Ethiopian Government considers irrigated agriculture as a primary engine of economic growth and plans to increase the current level of irrigation infrastructure three-fold by the end of 2015. However, there has been concern regarding the performance and management of existing small-scale irrigation. Based on the assessment of 52 small-scale irrigation schemes, and three case study sites, we describe the challenges and interventions required to improve irrigation water management in Ethiopia. Though most schemes are operational, many do not operate at full capacity, due to design failures, excessive siltation, poor agronomic and water management practices, and weak local institutions. In addition to low returns, there is competition for irrigation water between upstream and downstream users, vegetable growers and cereal growers, and between farmers with large irrigable plots and those with small plots. Despite these challenges, our field assessment revealed that small scale irrigation increases crop yields, improves crop diversification, and reduces the risk of crop failure. We emphasize in this paper the need for incentives to improve productivity and minimize conflicts, while enhancing innovation capacity, developing scheme-specific intensification strategies, and promoting collective action. We also describe how benefits from water investments could be substantially increased by overcoming design constraints, strengthening water user associations, and protecting catchments.

Research results published regarding the impact of soil and water conservation practices in the highland areas of Ethiopia have been inconsistent and scattered. In this paper, a detailed review and synthesis is reported that was conducted to identify the impacts of soil and water conservation practices on crop yield, surface run-off, soil loss, nutrient loss, and the economic viability, as well as to discuss the implications for an integrated approach and ecosystem services. The review and synthesis showed that most physical soil and water conservation practices such as soil bunds and stone bunds were very effective in reducing run-off, soil erosion and nutrient depletion. Despite these positive impacts on these services, the impact of physical soil and water conservation practices on crop yield was negative mainly due to the reduction of effective cultivable area by soil/stone bunds. In contrast, most agronomic soil and water conservation practices increase crop yield and reduce run-off and soil losses. This implies that integrating physical soil and water conservation practices with agronomic soil and water conservation practices are essential to increase both provisioning and regulating ecosystem services. Additionally, effective use of unutilized land (the area occupied by bunds) by planting multipurpose grasses and trees on the bunds may offset the yield lost due to a reduction in planting area. If high value grasses and trees can be grown on this land, farmers can harvest fodder for animals or fuel wood, both in scarce supply in Ethiopia. Growing of these grasses and trees can also help the stability of the bunds and reduce maintenance cost. Economic feasibility analysis also showed that, soil and water conservation practices became economically more viable if physical and agronomic soil and water conservation practices are integrated.

To tackle the problem of soil erosion and moisture stress, the government of Ethiopia introduced a yearly mass campaign where communities get together and implement various soil and water conservation (SWC) and water harvesting (WH) practices. Although the interventions are believed to have reduced soil erosion/sediment yield and enhanced surface and ground water, quantitative information on the impacts of various options at different scales is scarce. The objective of this study was to assess the impacts different land uses, SWC and WH interventions on water and suspended sediment yield (SSY) at plot and watershed scales in the central highlands of Ethiopia. Standard erosion plot experiments and hydrological stations were used to monitor the daily water and SSY during 2014 to 2017. The results show differences between treatments both at plot and watershed scales. Runoff and soil loss were reduced by an average 27 and 37%, respectively due to SWC practices at the plot level. Overall, SWC practices implemented at the watershed level reduced sediment yield by about 74% (in the year 2014), although the magnitude of sediment reduction due to the SWC interventions reduced over time. At both scales it was observed that as the number of years since SWC measures have been in place increased, their effectiveness declined due to the lack of maintenance. This study also revealed that extrapolating of plot data to watershed scale causes over or under estimation of net erosion.

Scaling is a ubiquitous concept in agricultural research in the global south as donors require their research grantees to prove that their results can be scaled to impact upon the livelihoods of a large number of beneficiaries. Recent studies on scaling have brought critical perspectives to the rather technocratic tendencies in the agricultural innovations scaling literature. Drawing on theoretical debates on spatial strategies and practical experience of agricultural innovation scaling in Ethiopia, this paper adds to the current debate on what constitutes scaling and how to overcome critical scaling constraints. The data for the paper came from a qualitative assessment using focus group discussions, key informant interviews, and document analysis on scaling work done in Ethiopia by a USAID-funded research for development project. The paper concludes with four broad lessons for the current understating of agricultural innovation scaling. First, scaling of agricultural innovations requires a balanced focus on technical requirements and associated social dynamics surrounding scaling targets, actors involved and their social relations. Second, appreciating the social dynamics of scaling emphasizes the fact that scaling is more complex than a linear rolling out of innovations towards diffusion. Third, scaling may not be strictly planned; instead, it might be an extension of the innovation generation process that relies heavily on both new and long-term relationships with key partners, trust, and continuous reflection and learning. Fourth, the overall implication of the above three conclusions is that scaling strategies need to be flexible, stepwise, and reflective. Despite the promises of flourishing scaling frameworks, scaling strategies it would appear from the Africa RISING experience that, if real impact is to be achieved, approaches will be required to be flexible enough to manage the social, processual and emergent nature of the practice of scaling.

Over the last three decades, land management practices have been extensively implemented in Ethiopia. Different attempts have been made to assess the effects of land management practices on soil loss at plot scales under a range of climatic and land use conditions. However, the plot-level studies were mostly focused on limited sites and were inadequate to show the effects of land management and land cover practices across a range of practices and under various environmental contexts. A meta-analysis of 82 plot-level experiments in 59 sites was conducted to assessing the effects of land management practices and land use/cover types on soil loss relative to control practice. Random effects were accounted for the association of soil loss and environmental factors including mean annual rainfall, soil texture, and slope length. The results showed that there were significant mean soil loss differences among the categories of land management and land cover practices (p < 0.049). A large amount of residual heterogeneity (I2 = 92%) suggests that the groups of practices are heterogeneous. Mechanical erosion control and agronomic practices with the largest number of studies and somewhat area closure showed large heterogeneity across experiments.The overall mean soil loss ratio of mechanical (0.086, R2 = 81%), agronomic (0.21, R2 = 85%), and area closure (0.09, R2 = 52%) practices were significant to reduce soil loss. There was no residual heterogeneity exhibited across studies for the rest of four groups of practices. The mean soil loss ratio of mechanical practices under non-cropland, annual cropland cover, drainage, and non-cropland cover types were 0.12, 0.14, 0.27, and 0.29, respectively. Yet, with a certain level of inconsistency, the overall effects of all groups of land management and land cover practices were positive. In general, the sensitivity of environmental factors and their magnitude of association with soil loss ratio could imply that the effects of the range of land management practices and land cover types on soil loss are very contextual.
