biodiversity act, 2002 summary

Biological diversity (biodiversity) is the occurrence of different types of ecosystems, different species of organisms with the whole range of their variants and genes adapted to different climates, and environments along with their interactions and processes. At its simplest, alpha diversity is species richness (i.e. For larger areas, in many studies of terrestrial environments, the term gamma diversity has been used to reflect the number of taxa on an island or in a distinctive landscape, and epsilon diversity has been used for the inventory diversity of a large biogeographical region; the term delta diversity is occasionally used for the variation between areas of gamma diversity within such a region. Agriculture depends on biodiversity for a variety of reasons, including as a source of present food security and insurance for future outbreaks of pests and diseases and climate change losses.

Assessment of the numbers of higher taxa has been an important facet of the analysis of biodiversity – one point sample or community may contain more species than another while having fewer higher taxa and possibly, therefore, a lower genetic diversity and morphological disparity. Other natural resource managers prefer to actively manage forests using common forestry or natural resource practices, which to some extent will allow natural processes to transform the forests but which will also influence biodiversity. Table 1. The monetary benefits, fees, and royalties, as a result of approvals by NBA, are to be deposited in the National Biodiversity Fund, which will be used for conservation and development of areas from where the resource has been accessed, in consultation with local self-government.

Biodiversity – the constellation of plants, animals, fungi, and microorganisms on Earth; their genetic variation; and the communities and ecosystems of which they are a part – is a central component of Earth’s life support systems. R. Dirzo, E. Mendoza, in Encyclopedia of Ecology, 2008. In 1992, 150 countries signed the Convention on Biological Diversity (CBD), Article 2 of which defines biodiversity for the purposes of global governance. It is based on a broad ecosystem approach rather than the sectoral approach (focusing on specific species, ecosystems, or sites) that is characteristic of other international conservation agreements. Currently, there are hundreds of entries annually, while the search of a typical research university’s holdings yields over 1000 entries containing biodiversity in the title.
