The publication describes outcomes of a study to assess the effectiveness of a large-scale crop seed relief effort in Zimbabwe during 2003-07. Aims of the effort, which was supported by the British Department for International Development (DfID) and coordinated by the Food and Agricultural...

Conventional agricultural practices such as the use of the moldboard plough are no longer sustainable due to their extensive soil degradation effects. As a panacea, several Conservation Agriculture (CA) technologies have been promoted to improve soil structure and water conservation. However,...

Researchers generally assume spatial homogeneity when assessing the factors that influence farmers to adopt improved agricultural technologies. However, the potential for spatial heterogeneity is high due to, for example, neighborhood effects such as farmers sharing information about new...

This paper compares two estimation methods of a three-stage least squares (3SLS) system of equations, corrected for spatial autocorrelation. The modeling approach is novel in that it is an extension of Anselin's (1988) seemingly unrelated regression (SUR) space-time spatial error model for panel...

Generating economic growth for the millions who live in poverty in developing countries is one of the key world problems of our time. In many cases, economic growth is driven by technological improvements. One of the technologies which could generate economic growth in Africa is biotechnology....

The goal of this research was to develop spatial regression methods to economically evaluate on-farm site-specific management (SSM) trials. Whether yields are collected with a combine yield monitor, a weigh wagon, or other technology, they usually have a spatial structure. Covariates including...

Due to a rapid yield decline, plantain fields in Southeastern Nigeria are reverted to fallow after two years. However, population pressure leads to shorter fallow periods and high rates of deforestation. This study investigates the potential of mulch-based systems for perennial plantain...
