By making use of national historical data and statistical analysis, this paper argues that community-based wildlife conservation is a feasible hedge asset for agricultural production in rural Zimbabwe.

In this paper we study the process of technical change in the case of pollution abatement from large stationary sources that have been regulated by a very forceful refunded emission payment policy.

This article analyzes the effects of the invasion of water hyacinth on fishing in Lake Victoria.

This paper integrates traditional economic variables, soil properties, and variables on soil conservation technologies to estimate agricultural output among small-scale farmers in Kenya’s central highlands. The study finds that integrating traditional economics and soil science is invaluable, especially as omitting measures of soil capital can cause omitted-variable bias. The central policy implication is that while fertilizers are generally beneficial, their application is a complex art, and more is not necessarily better.

Analysis of the differences in firms’ responsiveness to PROPER (Indonesia’s successful public disclosure program for industrial pollution control) showed that foreign-owned firms and firms in densely populated areas were more likely to respond to public environmental ratings. Firms with bad environmental performances felt pressure to improve, but this incentive diminished after the initial abatement steps.

The revitalization of Machakos, Kenya, from overpopulation and resource degradation—seemingly by its population growth—has added another round to the Boserupian vs. Malthusian debate, and may make Machakos unique.

This study investigated Machakos’ improvement by looking at the role of social capital with principal component analysis and found significant differences between Machakos and two other Kenyan regions, particularly in the formation of associations.

Raising the price of fossil fuels is a key component of any effective policy to deal with climate change. Just how effective such policies are is decided by the price elasticities of demand. Many papers have studied this without recognising that not only is there a demand side response: quantities are decided by the price but also there is a reverse causality: the level of consumtion affects the political acceptability of the taxes which are the main component of the final price.

This paper evaluates the effectiveness of the Program for Pollution Control Evaluation and Rating (PROPER) in Indonesia.

The Stern Review (2006) has come to symbolize something of a dividing line in the evolution of the common appreciation of the climate problem. It is fair to say that during the last decade there has been a gradual but uneven increase in the perceived gravity of anthropogenic climate change, both among scientists and, with some time lag, the general public.

The purpose of this paper is to create and discuss a measure of water hyacinth abundance in Lake Victoria. Water hyacinths have dramatic effects on other activities such as fisheries. However, understanding their spread and effects is hampered by the lack of reliable information.
