Since the early 1990s, liberalization of the seed market in Tanzania has attracted several foreign companies that now market maize hybrids in the country. In this article, we analyze the impacts of proprietary hybrids on maize yields, production, and household living standards. We build on a...

Modern technologies are often not widely adopted among smallholder farmers in Sub-Saharan Africa. Several adoption constraints have been discussed in the literature, including limited access to information. Using survey data from farmers in Tanzania and the average treatment effect framework, we...

This paper reviews recent advances in, and challenges for, weather index insurance for managing drought risk in smallholder agriculture, with a focus on sub-Saharan Africa. Despite its promise to integrate local agricultural risk smoothing with insurance principles, there remain many challenges...

The existence of an inverse relationship (IR) between farm size and productivity in tropical agriculture remains a debated issue with policy relevance. Poor agricultural statistical data, including data on farm sizes and farm plot sizes that typically are self-reported by farmers, can lead to...

This paper assesses the adoption potential of conservation agriculture (CA) technologies in Malawi, where CA appears highly appropriate. Estimation of CA adoption rates and their determinants is complicated by the relatively recent introduction of these technologies and limited awareness of CA...

This study investigates how the Farmer-to-Farmer-Extension (F2FE) system with lead farmers and follower farmers influences adoption of Conservation Agriculture (CA) technologies in Malawi. Using data from 180 lead farmers and their 455 followers in central and southern Malawi, we assess the...

Soil fertility management (SFM) technologies may potentially protect against climate risks, reduce nutrient depletion and enhance food security. In this paper, we study impact of drought exposure on adoption and adoption intensity of SFM technologies, specifically, focusing on maize-legume...

Minimum tillage combined with mulching (MTM) is critical to conservation agriculture, yet its use by smallholder farmers raises challenging questions regarding adoption, diffusion and scaling at farm level. In this paper, we used probit regression and post-estimation simulations to identify the...

Productivity and efficiency are key performance indicators of improved seeds. Efficiency differences explain part of the variation in productivity. Improved seeds may affect efficiency because farmers often do not apply inputs at optimum. Improved seeds therefore not only directly affect...

The paper examines the impact of land certification on tree growing on private plots of rural households in the Amhara and Tigray regions of Ethiopia. Household and plot level panel data from before and after land certification from stratified random samples of households were used for the...
