Which of the following can be threats to the biodiversity of a geograp...
- Five main threats to biodiversityare commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation. Unless we successfully mitigate the impacts of these direct drivers of change on biodiversity, they will contribute to the loss of biodiversity components, negatively affect ecosystem integrity and hamper aspirations towards sustainable use.
- In discussing threats to biodiversityit is important to keep in mind that, behind these direct drivers of biodiversity loss, there are a number of indirect drivers that interact in complex ways to cause human-induced changes in biodiversity. They include demographic, economic, socio-political, cultural, religious, scientific and technological factors, which influence human activities that directly impact on biodiversity.
- Indicators for trends in nutrient loadingand invasive alien species have been identified under the focal area addressed here, and are described below. Information on habitat change is provided by the indicator trends in extent ofselected biomes, ecosystems Overexploitation is discussed under the focal area on sustainable use While there is no single indicator of the impacts of climate change on biodiversity, a number of indicators, including those on trends in extent of selected biomes, ecosystems and habitats (particularly applied to coral reefs, polar ice and glaciers, and certain types of forests and drylands), abundance and distribution of selected species and incidence of human induced ecosystem failure, can serve to derive trends where specific data are available. Because small, fragmented ecosystems are more affected by changes in temperature and humidity than large contiguous ecosystems with a more balanced micro-climate, trends in connectivity/fragmentation of ecosystems provide an indicator of the vulnerability of ecosystems to climate change.
