Economywide assessment of CSA interventions in building resilient agri-food systems in Rwanda

Due to its structural features, the Rwanda’s agri-food system is extremely vulnerable to the risks of climate variability. To accelerate and sustain growth in the food system, increase its resilience to shocks, and improve food security, the Rwandan government incorporated a list of climate-smart agricultural interventions into its updated Fifth Strategic Plan for Agricultural Transformation (PSTA-5) program, with ambitious, explicit targets. This paper assesses the impacts of these CSA interventions on Rwanda’s agri-food system, both with and without climate change, using historical declines in yield within agriculture as a proxy. Results show that modeled CSA practices during the PSTA-5 period (2024/25-2028/29) increase agricultural and overall GDP growth by 4.2 and 1.3 percentage points by the end of the plan period, respectively, with a long-term growth impact that stretches well beyond the plan period mainly owing to the persistent effects of irrigation and terracing. Cumulative agricultural GDP (2024/25-2028/29) would be 2.7 percent higher than the baseline outcome of no such CSA investments. We also find stronger household level effects, mainly in rural areas. Furthermore, a recurrent 1-in-5-year magnitude of climatic shock in Rwanda can cause substantial reductions in agricultural (-7.6 percent) and overall (-2.7 percent) GDP during the PSTA-5 period. The CSA interventions are impactful in minimizing the effects of climate change on the Rwandan economy.

Synopsis: Cost effective options for inclusive and sustainable development in Rwanda

Synopsis: Cost effective options for inclusive and sustainable development in Rwanda

The study systematically ranks investment options in the agrifood system based on their cost-effectiveness across multiple development outcomes. Investments in SME processors and traders and livestock extension are the most cost-effective for promoting agrifood GDP growth and employment. SMEs and livestock services together with seed systems and credit access contribute positively to social outcomes (poverty, undernourishment, and diet). The analysis finds a trade-off between economic gains and environmental outcomes— higher GDP effects often come with greater environmental costs. The Rwandan case demonstrates a slight shift in the relative cost-effectiveness of investments when accounting for historical climatic risks. The study emphasizes the need for data-driven investment planning, climate-aware policies, and balancing short-term gains with long-term sustainability objectives.

Rwanda: Cost effective options for inclusive and sustainable development

In this policy brief, we present research findings of a systematic evaluation and ranking of investment options for Rwanda’s agrifood system based on their cost-effectiveness in achieving multiple devel opment outcomes, including agrifood gross domestic product (GDP) growth, agrifood job creation, poverty reduction, declining rates of undernourishment, and lowering diet deprivation. Additionally, the study assesses their environmental footprint, focusing on water consumption, land use, and emissions. Investments in small and medium enterprise (SME) processors are shown to be the most cost-effective at expanding agrifood GDP and employment, while extension and advisory services on livestock and climate emerge as the most efficient farmer-facing investments. However, crop ex tension services rank least in cost-effectiveness for economic and social outcomes. However, many cost-effective investments have relatively high environmental footprints, which highlights potential tradeoffs. The study further reveals shifts in the cost-effectiveness ranking of investment options overtime and when extreme production shocks occur.
