Agricultural Production and Technology

The Government of Ghana (GoG) since 2007 has been providing subsidized agricultural machines to individual farmers and private enterprises established as specialized Agricultural Mechanization Services Enterprise Centers (AMSECs) to offer tractor-hire services to small-scale farmers across the country. Current demand in the country is primarily focused on land preparation services, especially plowing. This paper assesses whether AMSEC enterprises are a viable business model attractive to private investors.

This paper contributes new empirical evidence and nuanced analysis on the gender difference in access to extension services and how this translates to observed differences in technology adoption and agricultural productivity. We employ a cross-sectional instrumental-variable regression method using a regionally-representative dataset of more than 7,500 households and 32,000 plots in four major regions in Ethiopia that was collected during the 2010 main season.

This study analyzed the impact of off-farm earnings on the intensity of adoption of improved maize varieties and the productivity of maize farming in Uganda in the years 2005/06 and 2009/10. Summary statistics show significantly higher adoption intensity and expenditure on purchased inputs among households with off-farm income relative to their counterparts without off-farm income.

The improved performance of the agricultural sector in Africa south of the Sahara during the most recent decade (2000–2010) has raised questions about the drivers behind the growth. Skeptics argue that rising commodity prices, as world markets experience a commodity boom, are the main cause of the agricultural growth. Others point to improvements in the policy environment and increased investments in agriculture at a time when African governments and donors have been rallying to increase their support to agriculture.

Rainfall shortage is a major production risk for smallholder farmers. Due to rainfall shortage, smallholders limit the use of modern inputs such as fertilizer and improved seeds. This study investigates if water harvesting technologies (WHTs) induce fertilizer use and whether there is joint adoption of fertilizer and water harvesting technologies. Using panel data collected from Ethiopian farmers in two regions in 2005 and 2010, a random effects probit model and a bivariate probit model are estimated to investigate these two issues.

Irrigation development is rapidly expanding in mostly rainfed Sub-Saharan Africa. This expansion underscores the need for a more comprehensive understanding of water resources beyond surface water. Gravity Recovery and Climate Experiment (GRACE) satellites provide valuable information on spatio-temporal variability in water storage.

In the three major maize producing countries in the East African region of Kenya, Tanzania and Ethiopia, up to 44% of the dietary calorie requirements is provided by maize. It is also recognized that livestock are an essential asset of poor farmers in the mixed crop-livestocksystems in this region. One of the major constraints to their productivity is, however, feed availability. A significant proportion of this feed is sourced from maize stover. We engaged in a multi-disciplinary research of dual-purposemaize cultivars with the purpose of contributing to smallholder food security.

The Comprehensive Africa Agriculture Development Programme (CAADP) provides an agriculture-led integrated framework of development priorities aimed at reducing poverty and increasing food security by achieving an average of 6 percent agricultural growth rate every year.

Licensing the exploitation of forest resources is often used as a preferred policy to regulate natural resource management in developing countries. Based on survey data from 178 charcoal traders, this paper studies the regulated charcoal trade in Madagascar and tests if regulatory control through a licensing system leads to rents (i.e., excess payments above those required to induce or provide for production) in charcoal trade. Two main findings were made.
