Ecological, evolutionary and economic issues involved in introducing genetically modified organisms (GMOs), mainly in agriculture, are discussed. The ecological and evolutionary impacts identified hamper (economic) valuation of GMOs and their biosafety regulation and creates difficulties for...

Analyzes the economics of alternative allocations of forested land for uses (dominant-use vs. multiple use) to ensure the survival of a viable population of a forest-dependent species, e.g. the orangutan. The alternatives are (1) setting aside a sufficient fully protected portion of the forest...

Biodiversity is usually regarded as an asset or resource, the stock of which is partly natural and partly determined by humans. Humans both subtract from and add to this stock and consequently, the change in the stock is heterogeneous. This heterogeneity is not taken account of by some authors...

Provides some background on concerns about the sustainability of agriculture, outlines and discusses views about what constitutes sustainable agriculture and contrasts the sustainability of modern industrialised agriculture with that of traditional agriculture. Then the question is considered...

The production of biofuels has been supported by many conservationists and environmentalists on the grounds that it reduces greenhouse gas emissions and is a renewable energy substitute for non-renewable fossil fuels, mainly oil. More recently the domestic production of biofuels (and the...

Despite growing attention to crop and property damage caused by the Asian elephant, uncertainty exists about the magnitude of this problem. This paper explores the nature and magnitude of this problem of Sri Lanka. An economic analysis of individual farmers’ decisions to control elephants is...

This paper provides an overview of concepts of sustainable agriculture and possible methods of attaining sustainability of agricultural yields and production. Reasons are given as to why modern industrialised agriculture might be less sustainable in terms of yields than traditional agriculture....

This paper explores the way in which the stated willingness to pay for the conservation of Asian elephants in Sri Lanka varies with hypothetical variations in their abundance. To do that, it relies on results from a sample of residents of Colombo. The willingness to pay function is found to be...

As former communist countries have proceeded with market reforms, they have become more enmeshed in the international economy and their involvement in economic globalisation continues to grow. While economic theory suggests that this should bring several economic advantages to transitional...
