This paper provides a theoretical framework to analyse land quality and labour allocation decisions by poor rural households in the context of increased population densities in slash-and-burn (shifting cultivation) agro-ecosystems. A bio-economic optimal control model is presented and its results calibrated with data from two farming communities from Yucatan (Mexico).

The environmental impact of industrial agriculture is under close scrutiny, by Governments, concerned citizens, and farmers. This paper discusses the need to incorporate environmental factors in measures of farm performance, as part of the continuous review of long term sustainability.

The aim of the study presented in this article is to identify existing conflicts of land use and ownership in the 'Landwirtschaftszone', together with the problems arising therefore. This paper discusses determinants of farmland prices in Canton Zurich.

This paper advances an empirical model assessing how, over both time and space, changes in land-use respond to changing economic and ecological conditions.

This paper examines the impact of having a preservation program on the rate of farmland loss for a 50 year period (1949-1997) in six Mid-Atlantic States: Delaware, Maryland, New York, New Jersey, Pennsylvania, and Virginia.

The world-wide trend of a growing organic sector is also detectable in South Africa. From 2000 to 2002 the number of farmers who had converted to organic farming in South Africa increased sixfold, and although organic farming still accounts only for a minute percentage of the total number agricultural producers, the increasing importance of this sector is apparent.

This paper develops a model to examine the impacts of uncertainty about crop production and irreversibility of program participation on determining land rental payments and least-cost land retirement targeting in the Conservation Reserve Enhancement Program.

Applying the Environmental Kuznets Curve hypothesis, the economic structure of pesticide consumption in the world was examined and its future consumption was predicted. It was found that the hypothesis is applicable and the income level significantly affects the pesticide consumption. Additionally, sustained population per land is also influential.
