Mozambique: Cost effective options for inclusive and sustainable development

In this policy brief, we present findings of a systematic evaluation and ranking of investment options for Mozambique’s agrifood system based on their cost-effectiveness in achieving multiple development outcomes, including agrifood gross domestic product (GDP) growth, agrifood job creation, poverty reduction, declining undernourishment, and lowering diet deprivation. Additionally, the study assesses their environmental footprint, focusing on water consumption, land use, and emissions. In Mozambique, investments in small and medium enterprise (SME) processors and traders are identified as the most cost-effective means of enhancing social outcomes, such as poverty reduction and addressing undernourishment. They are also highly ranked in accelerating agrifood GDP and employment. Moreover, extension services for livestock and agronomy, rural road infrastructure, and post-harvest losses reduction are also highly ranked. However, many of these cost-effective investments come with relatively high environmental footprints, which highlight potential tradeoffs. The study further reveals shifts in the cost-effectiveness ranking of investment options over time and marginally so in the presence of extreme production shocks.

Zambia: Cost effective options for inclusive and sustainable development

In this policy brief, we present findings of a systematic evaluation and ranking of investment options for Zambia’s agrifood system based on their cost-effectiveness in achieving multiple development outcomes, including agrifood gross domestic product (GDP) growth, agrifood job creation, poverty reduction, declining 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) traders and processors are shown to be the most cost-effective at driving improvements in social outcomes, like poverty and undernourishment. They are also highly ranked in terms of expanding agrifood GDP and employment. Expansion in extension and advisory services for livestock, rural roads, farmers credit, and seed systems also rank high. How ever, 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.

Tanzania: 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 Tanzania’s agrifood system based on their cost-effectiveness in achieving multiple development 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 extension and advisory services on livestock are shown to be the most cost-effective in expanding agrifood GDP and jobs. We also find that targeting SME processors generates stronger impacts on jobs, while extension services in agronomy are particularly cost-effective in fostering growth. Similarly, investing in extension services in agronomy and livestock, along with support to SME processors, yields significant gains in social outcomes, though with varying effects on poverty, hunger, and diet quality. However, many cost-effective investments have relatively high environmental footprints, highlighting potential tradeoffs. The study further reveals shifts in the cost-effectiveness ranking of investment options over time and when extreme production shocks occur.
