Report on small-scale irrigation’s contributions to increased income, economic growth and market opportunities
No full textFarmers, entrepreneurs, and businesses are already leading the way by expanding irrigation in response to climate variability and the growing demand for vegetables and fruit through supplemental and dry-season irrigated production. Increasing commercialization creates market opportunities throughout irrigated value chains. The Feed the Future Innovation Lab for Small Scale Irrigation (ILSSI), has supported research and partnerships with companies and producer groups to innovate technologies, share information, and develop inclusive, market-based approaches that catalyze investment in irrigation.Non-PRIFPRI5; 1 Fostering Climate-Resilient and Sustainable Food Supply; 4 Transforming Agricultural and Rural Economies; G Cross-cutting gender themeDevelopment Strategies and Governance (DSG); Transformation Strategies; Natural Resources and Resilience (NRR

Integrating institutions into a socio-hydrological model: An example for water quality management in Burkina Faso
No full textThe variety of demands that people place on water resources, coupled with the dynamics of the natural system, make water resource management highly complex. Models that can integrate aspects of society such as institutions, perceptions and behaviors along with aspects of the natural system such as rainfall, runoff and water quality could offer a realistic approach to better understand and manage these complex systems. Much research progress in the development of such socio-hydrological models has been achieved in recent years. However, many gaps exist on how the decisions and actions of institutions and agencies, and their subsequent impacts on individuals, can be integrated within such models. In this study, a socio-hydrological model was developed using a set of empirical field data from the Black Volta (Mouhoun) watershed in south west Burkina Faso. Cultivation of the riparian zones and use of agrochemicals are commonly associated with increased sedimentation in the river and water pollution, respectively. The model aims to capture the relationships between agency support for water quality management, the capacity of local organizations to support farmers and land users, land use changes in the riparian zones, improved agricultural practices employed by farmers (e.g., reduced tillage, organic farming, or cultivating tree crops rather than vegetables), and suspended sediment concentration in the river as an indicator of water quality. The model is set up to reflect the current situation and scenarios are generated depicting plausible pathways to achieve improved water quality through riparian land management strategies. Comparison of the modelled scenarios shows that water quality could be improved if institutional support and public resource allocation for water management is raised, and the capacity of local level organizations is substantially increased compared to current levels. Semi-quantitative socio-hydrological models, such as the one developed in this study, may provide insights for the comparison and prioritization of different management strategies and guide interventions or support mechanisms that enable riparian land users to change their agricultural practices and lead to water quality improvements.Non-PRIFPRI5; CRP2; CRP5; 1 Fostering Climate-Resilient and Sustainable Food Supply; 5 Strengthening Institutions and Governance; Capacity StrengtheningDSGD; PIMCGIAR Research Program on Policies, Institutions, and Markets (PIM); CGIAR Research Program on Water, Land and Ecosystems (WLE
Exploring water quality management with a socio-hydrological model: A case study from Burkina Faso
No full textModels that can integrate aspects of society such as institutions, perceptions and behaviours with aspects of the natural system such as rainfall, runoff and water quality may help understand and manage complex human-water systems. In this paper, a socio-hydrological model is developed for the Black Volta (Mouhoun) watershed in Burkina Faso. The model captures the relationships between the awareness to water quality issues and capacity of local organizations, land use in the riparian zone, agricultural practices and suspended sediment concentration as an indicator of water quality. Scenarios are generated for the current situation and for plausible pathways to achieve improved water quality through different riparian land management strategies. Scenario comparison show how water quality improvements are generated if institutional support, resources and capacity of local level organizations are substantially increased compared to current levels.PRIFPRI3; 4 Transforming Agricultural and Rural Economies; 5 Strengthening Institutions and Governance; Capacity Strengthening; ISIDSG

Degradation of water resources in rural Burkina Faso: Drivers, local perceptions and solutions
No full textBurkina Faso reformed its water management institutions and adopted integrated water resources management (IWRM) for more than two decades, yet the country still suffers from weak institutions and ineffective implementation of water management reforms. The key institutional question is: “How can IWRM reforms be adapted to increase effectiveness and sustainability of water management, and improve livelihoods of rural populations through increased participation of local stakeholders?” A key practical issue related to this bigger institutional question is to understand the barriers to adoption of good land and water management measures by riparian farmers and other land/water users, and the mechanisms to induce behavioral change among these users. Knowledge gaps exist in understanding the local perceptions and preferences of alternative management measures, and the incentive mechanisms to induce behavioral change. The aim of this study, which was part of a 3-year project entitled ‘Participatory planning for more inclusive and sustainable water management in rural Burkina Faso’, was to understand the perceptions, preferences and willingness of farmers and other land/water users to adopt environmentally friendly land and water management measures. The study also examined potential mechanisms that could induce riparian economic actors to adopt such measures.Non-PRIFPRI5; CRP5; Capacity Strengthening; 1 Fostering Climate-Resilient and Sustainable Food Supply; 4 Transforming Agricultural and Rural Economies; 5 Strengthening Institutions and GovernanceDSGDCGIAR Research Program on Water, Land and Ecosystems (WLE
Economic analysis of public investment in alternative agricultural water management schemes: A case study from northern Ghana
No full textThis study assesses the institutions and economics of public investments in three agricultural water management infrastructure and technologies: rehabilitation of small reservoirs, fuel-powered motorized small pumps and electricity-powered large pumps. We find that all three technologies yield positive returns on investment, but their applicability varies spatially and across community due to differences in capital costs and environmental feasibilities or conditions. Sensitivity analyses indicate the base decision parameters – net present value, benefit–cost ratio and internal rate of return – remain stable despite potential changes in the flow of future benefits or costs. This provides further evidence about the worthiness of investment in irrigation infrastructure and technologies. However, significant under-utilized infrastructural capacities exist that warrant complementary investment in human and institutional capacities. Based on the findings policy recommendations are provided.PR1 Fostering Climate-Resilient and Sustainable Food Supply; 4 Transforming Agricultural and Rural Economies; 5 Strengthening Institutions and Governance; IFPRI3; ISIDevelopment Strategies and Governance (DSG); Transformation Strategie
Climate change, income sources, crop mix, and input use decisions: Evidence from Nigeria
No full textThis paper combines panel data from nationally representative household-level surveys in Nigeria with long-term satellite-based spatial data on temperature and precipitation using geo-referenced information related to households. It aims to quantify the impacts of climate change on agricultural productivity, income shares, crop mix, and input use decisions. We measure climate change in harmful degree days, growing degree days, and changes in precipitation using long-term (30 year) changes in temperature and precipitation anomalies during the crop calendars. We find that, controlling for other factors, a 15 percent (one standard deviation) increase in change in harmful degree days leads to a decrease in agricultural productivity of 5.22 percent on average. Similarly, precipitation change has resulted in a significant and negative impact on agricultural productivity. Our results further show that the change in harmful degree days decreases the income share from crops and nonfarm self-employment, while it increases the income share from livestock and wage employment. Examining possible transmission channels for this effect, we find that farmers change their crop mix and input use to respond to climate changes, for instance reducing fertilizer use and seed purchases as a response to increases in extreme heat. Based on our findings, we suggest policy interventions that incentivize adoption of climate-resilient agriculture, such as small-scale irrigation and livelihood diversification. We also propose targeted pro-poor interventions, such as low-cost financing options for improving smallholders’ access to climate-proof agricultural inputs and technologies, and policy measures to reduce the inequality of access to livelihood capital such as land and other productive assets.Non-PRIFPRI1; 1 Fostering Climate-Resilient and Sustainable Food Supply; Feed the Future Nigeria Agricultural Policy Project; Feed the Future Initiative; NSSPDevelopment Strategies and Governance (DSG); Transformation Strategie
