1. Introduction
As defined by the Convention of Biological Diversity (CBD) biodiversity is “the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and ecological complexes of which they are not part, diversity within species and of ecosystems” (IUCN, 2000).
The continued growth of human populations and per capita consumption have resulted in unsustainable exploitation of the Earth’s biological diversity, exacerbated by climate change, ocean acidification and other anthropogenic environmental impacts. The ecosystems exploited, provide essential services, including material goods such as food and timber; cultural and recreational benefits as well as providing other functions necessary for climate regulation, flood control and nutrient cycling. The key pressures to biodiversity loss are overexploitation, invasive alien species, pollution, climate change and the degradation and fragmentation of habitats. However, there are many challenges that effect the management of these pressures as a result of social and economic needs and as a result, further scientific research is required in order to best identify the distribution and appropriate management schemes for different areas.
Globally, the efforts to reduce anthropogenic impacts on ecosystems have been addressed by the United Nations CBD. The goal of reducing…
