This study assesses public investment required for agricultural growth and poverty reduction in Nigeria. Using time series data for public spending and agricultural total factor productivity (TFP) growth, the econometrically estimated results show that one percent of growth in agricultural...

We study the impact of export bans in Tanzania using a computable general equilibrium model. We find that although maize is an important food crop in Tanzania, its contribution to food price inflation is rather limited, and that banning cross-border maize exports lowers the national food price...

This paper presents the findings of a local economywide impact evaluation of Feed the Future irrigation projects in the Morogoro region of Tanzania, using a local economy-wide impact evaluation (LEWIE) simulation model. The findings indicate that these irrigation projects can generate important...

Even though the intention of the government is to promote private sector-led mechanization, findings suggest that the AMSEC model is unlikely to be a profitable business model attractive to private investors even with the current level of subsidy. The low tractor utilization rate as a result of...

"We identify a set of development priorities for agriculture that cut across West Africa, at both the country and the regional level, to achieve economy-wide growth goals in the region. To do this, we adopt a modeling and analytical framework that involves the integration of spatial analysis to...

"We develop a detailed trade analysis to assess the potential welfare impacts of a free trade agreement (FTA) on the agricultural sector of southern African countries and to determine opportunities and challenges faced by the region as a consequence of the agreement. Our approach combines an...

Economy-wide and hydrological-crop models are combined to estimate and compare the economic impacts of current climate variability and future anthropogenic climate change in Zambia. Accounting for uncertainty, simulation results indicate that, on average, current variability reduces gross...
