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...

In the Millennium Ecosystem Assessment (2005), ecologists identified and pointed out a multitude of environmental and other benefits obtained by human-beings from ecosystem services. Frequently, these benefits are not fully recognized and they are not adequately taken into account in...

After touching on the concerns of natural scientists about biodiversity loss, this article argues that it is a mistake to believe that there are only losses of biodiversity. The process of changes in the stock of biodiversity is more complex. Furthermore, it is pointed out that not all genetic...

The most widely accepted view of sustainable economic development is that it is economic development ensuring that each succeeding generation is no less well off than its predecessor. This mainstream approach, however, has several limitations. It can, for example, result in a development path...

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...

Indicates some of the different concepts of sustainable economic development and raises queries about how much present generations are concerned with future generations. A variety of conditions (ranging from very weak to very strong) have been suggested for achieving sustainable development....

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...

Different economic methods are being used to estimate the economic benefits generated by nature (wildlife) tourism. The most prominent of these are economic valuation analysis and economic impact analysis. These methods often provide divergent and conflicting estimates of the economic benefits...
