Conditional contracts in indirect local procurement of maize from smallholder farmers in Uganda: A study design to assess impacts

Improving smallholder farmers’ access to reliable markets can have significant impacts on their wellbeing, income, poverty reduction, dietary diversity, and rural economic growth. As the choice of marketing channels may influence outcomes differently depending on the context, a key issue is understanding the effectiveness of different marketing instruments. One such modality is a conditional contract between a buyer and the traders supplying it. Such a contract requires traders to source a certain percentage of their supplies directly from smallholder farmers. This raises the question of whether conditional contracts create access to reliable markets for smallholder farmers, result in value chain transformation, and sustain market engagement between traders and smallholder farmers.

Making the CAADP BR forward looking: A decision support tool for transforming African agrifood systems

Making the CAADP BR forward looking: A decision support tool for transforming African agrifood systems

This paper presents an Excel-based interactive decision-support tool that policymakers and development practitioners can use to evaluate policy options to achieve targeted outcomes of the Malabo Declaration at the country level. The tool is based on a partial equilibrium simulation model that allows the user to simulate different scenarios based on the desired level of change in one outcome or more. For each scenario that is created, the simulated results provide information on the level of change required in each of the policies included in the model, the level of change in the other outcomes included in the model, and the allocation of the resources provided, including reallocation of some of the existing resources. A prototype of the tool that is developed using the fourth biennial review (BR) data on Ghana, which has some quality issues, is presented to demonstrate the potential features and utility of the tool. Limitations of the model and further work that is required to develop the actual tool for reliable policy evaluation are discussed. The latter includes using accurate data on the various indicators and expanding it to cover more years, in addition to developing a web-based interactive version of the tool.

Two decades after Maputo, What’s in the CAADP ten percent? Determinants and effects of the composition of government agriculture expenditure in Africa

This paper analyzes the determinants of the composition of government agriculture expenditure (GAE) in Africa and estimates the effect of the composition on agricultural productivity using cross-country annual data from 2014 to 2020 and structural equations modeling methods. It includes different specifications of the explanatory variables to assess the sensitivity of the results to different assumptions of the conceptual variables that are hypothesized to affect the composition and pathways of impact of government expenditure. The results show that there is a wide variation in GAE across African countries, and few have achieved the 10 percent CAADP agriculture expenditure target. Most African countries spend much smaller proportions of the national budget on agriculture than the sector’s share in the economy, and total agriculture expenditure seems to be allocated across subsectors according to their relative contribution to the sector’s output, with forestry and fisheries being slightly favored compared with crops and livestock, which dominate the sector. The allocation is also affected by several factors, such as past output and size of the subsector, official development assistance, education, irrigation, and state of agricultural transformation, although there are cross-subsector differences in their influence. There are also subsector differences in the estimated effect of GAE on land productivity: 0.06 to 0.08 for expenditure on the total sector, 0.02 for research, 0 to 0.09 for crops, 0 to 0.08 for livestock, and 0 to 0.07 for fisheries. The lower bound of zero means that the estimated effect is not statistically significant in some of the model specifications, such as whether cross-subsector expenditure effects are considered. We discuss implications of the results and suggestions for future research.
