A stochastic production technology that allows risk effects of factor inputs was estimated for maize farmers in Ethiopia. The results suggested that the promoted improved maize technology exhibits constant returns to scale whereas non-adopters use decreasing returns to scale technology. The...

An input-output framework with environmental accounting module was used to investigatethe implications of liberalising agricultural trade on the environment in South Africa. Theresults showed that trade liberalisation in the case of agricultural commodities will lead toenvironmental improvement....

Economists and statisticians constructing the national income accounts usually overlook the many benefits derived by communities from natural forests and woodlands. This study attempted to impute a value for the ecosystem services of these resources in Swaziland employing an environmental...

In this article, we demonstrated the dynamic impact of a bumper harvest and drought shocks on the maize market and on the trade regime in Ethiopia. Regional market integration of Ethiopia's white maize market with the South Sudan and Kenyan maize markets was also examined using cointegration...

This study employed a Ricardian model that captures farmers' adaptation to analyze the impact of climate change on South African Sugarcane production under irrigation and dryland conditions. The study utilized time series data for the period 1977 to 1998 pooled over 11 districts. Results showed...

A parametric approach was followed in this study to analyse milk production and supply systems based on farm level production cost data from a cross-section of dairy farms in South Africa for the 1997/1998 production year. Both single equation and system estimation techniques were applied to...

This paper applied an extended total factor productivity analysis to compare the resource use efficiency of alternative cropping systems in eastern Ethiopia. The results indicated considerable variation in resource use efficiency among cropping systems. Intercropping of sorghum with pulses in...

Economists and statisticians constructing the national income accounts usually overlook the many benefits derived by communities from natural forests and woodlands. This study attempted to impute a value for the ecosystem services of these resources in Swaziland employing an environmental...

Using a data set collected in eight districts of Uganda, this study investigates how investment in soil fertility management (SFM) and conservation practices may affect natural resource outcomes, particularly the extent and level of soil erosion and soil nutrient loss. The study used ordered...
