This paper examines partial agricultural land and labour productivity in 1975 and 1980, for different world regions. The results suggest that land and labour productivity are higher in developed countries relative to developing countries. However, agricultural labour productivity differences are...

This paper presents a bio-economic model of Andit Tid, a severely degraded crop-livestock farming system with high population density and good market access in the highlands of Ethiopia. Land degradation, population growth, stagnant technology, and drought threaten food security in the area....

A stated objective of the Ethiopian Government since it came to power in 1975 has been to increase the production of crops for both domestic consumption and export. Consequently, a number of plans and programs have been proposed and implemented to bring about such development in Ethiopian...

This article presents a modelling system for synthesising heterogeneous productivity and nutrient loading potentials inherent in agricultural cropland for policy use. Phosphorus abatement cost functions for cropland farmers in a southeastern Minnesota watershed are metamodelled using frontier...

This paper quantitatively analyses the cost-effectiveness of alternative green payment policies designed to achieve a targeted level of pollution control by heterogeneous micro units. These green payment policies include cost-share subsidies that share the fixed costs of adoption of a...

The effects of land sales restrictions on credit use, land investment and cultivation decisions are investigated using data from two villages in south India. Sales restrictions are found to have little effect on credit supply and demand or demand for land improvements. Some household...

Degradation of land continues to pose a threat to future food production potential in many developing economies. Various approaches, mainly based on command-and-control policies, have been tried (with limited success) in the past to encourage adoption of erosion-control practices by farm...
