Absentee tenants and farmland transfers in sub-Saharan Africa
We use a unique dataset from Malawi that matches tenants and their landlord counterparts to document the role played by absentee tenants, i.e. tenants who reside outside the area where the rented land is located. We found that non-local tenants made up 22% of the tenants in our sample. A significant subset of them had higher off-farm income and significantly more assets than did other tenants. Conversely, we found that 76% of landlords rented lan…
The role of active soil carbon in influencing the profitability of fertilizer use
We use recent plot‐level panel data from Tanzanian smallholder farmers to investigate maize yield responses to inorganic fertilizer under variable soil carbon conditions. Unlike many prior studies which consider total carbon measurements, we focus on active soil carbon, which is a component strongly related to key soil functions, such as nutrient cycling and availability. Active soil carbon is found to be a strong predictor of maize yield respons…
A revisit of farm size and productivity
The relationship between farm size and productivity has been studied extensively in the agricultural and development economics literature. However, most of the documented evidence in sub-Saharan Africa (SSA) is based on samples of small-scale farms operating 5 ha or less, with very little evidence assessing this relationship over a wider range of farm sizes. This omission is especially important considering the rapid expansion of medium-scale far…

Africa’s Unfolding Economic Transformation
Despite the continued deep challenges that the region is facing, mounting evidence points to profound economic transformation in sub-Saharan Africa since the early 2000s. The contributions in this special issue highlight three aspects of Africa’s unfolding economic transformation since 2000: remarkable progress for the region as a whole, highly uneven progress across countries, and unresolved questions about the sustainability of the transformati…
Africa's changing farm size distribution patterns
This study assesses changes over the past decade in the farm size distributions of Ghana, Kenya, Tanzania, and Zambia, drawing on two or more waves of nationally representative population‐based and/or area‐based surveys. Analysis indicates that much of Sub‐Saharan Africa is experiencing major changes in farm land ownership patterns. Among all farms below 100 hectares in size, the share of land on small‐scale holdings under five hectares has decli…
Land pressures, the evolution of farming systems, and development strategies in Africa
Evidence assembled in this special issue of Food Policy shows that rising rural population densities in parts of Africa are profoundly affecting farming systems and the region’s economies in ways that are underappreciated in current discourse on African development issues. This study synthesizes how people, markets and governments are responding to rising land pressures in Africa, drawing on key findings from the various contributions in this spe…
Input subsidy programs in sub‐Saharan Africa
Input subsidy programs have once again become a major plank of agricultural development strategies in Africa. Ten African governments spend roughly US$1 billion annually on input subsidy programs (ISPs), amounting to 28.6% of their public expenditures on agriculture. This article reviews the microlevel evidence on ISPs undertaken since the mid 2000s. We examine the characteristics of subsidy beneficiaries, crop response rates to fertilizer applic…
Pathways into and out of Poverty
This study identifies the factors associated with smallholder farm households that have risen out of poverty or descended into poverty between 1997 and 2007 in Kenya. The study uses data from a nationwide balanced panel of 1,275 households and data from detailed retrospective ‘life history’ survey of 84 households that had experienced either an appreciable improvement or decline in their asset wealth over the 10-year panel period. The results ind…

Impact of Aids-Related Mortality on Farm Household Welfare in Zambia
This article uses nationally representative panel data on 5,420 rural households in Zambia, surveyed in 2001 and 2004, to measure the impacts of HIV/AIDS‐related prime‐age mortality on livelihoods. Using age group and drought shock interactions as instruments for prime‐age mortality, we find that prime‐age mortality is endogenous in pooled OLS models. However, differencing the time‐invariant unobserved household characteristics largely addressed …
