Although improvements in human health represent a crucial aspect of development worldwide, many trends associated with development and global change appear to be reducing health security. In this article, we define the human epidemiological environment and describe key biophysical, economic,...

Economic models for assessing costs of greenhouse gas abatement can be classified as macroeconomic (top-down) models or micro (bottom-up) models. As yet little attention has been focused on the modelling of developing countries. This paper proposes a methodology for integrating the two...

The sustainability of natural resource use is influenced by population pressure, but this exercises a much less critical impact than the overall policy framework. In Colombia, various agricultural and other policies whose effect is to constrain the poor's access to land encourage environmental...

This article offers an account of the economics of the environment. I sketch the subject's motivation and scope, and try to identify what we know and what we don't as yet know about matters of concern. This demands brazen selection, and I haven't avoided it: for the most part, the article...

This paper models joint implementation (JI) for emission reduction between a developed and a developing country. When the per unit price of JI abatement is negotiated, the relative pay-offs deviate from the ratio of bargaining powers. When firms bargain, country-wise gains can increase with a...

The search for sustainability indicators should be guided by a theory of sustainable development (SD). In this paper we investigate two such theoretical frameworks and the indicators that they suggest. Indicators associated with weak sustainability are characterized by aggregative indicators...

To protect the elephant, trade in ivory has been banned since 1990. In this paper, we demonstrate that this ban's effect on elephant populations is ambiguous. Depending on the discount rate, among other things, the trade ban can either increase or decrease optimal population size. If the...

This paper seeks to develop a basic analytical framework that can be used to trace the environmental impacts of macroeconomic policies, and especially to identify where unforeseen negative environmental effects may occur and design remedial measures. The framework is based on a formal...
