Large portions of the continent may become uninhabitable as a result of the rapid effects of climate change, which would have disastrous effects on human health, food security, and poverty. [41] [42] [43] Regional effects on rainfall in the tropics are expected to be much more spatially variable. The direction of change at any one location is ...
The direct causes of deforestation within the DRC are well understood and have been identified consistently by many sources. [2] [3] [9] The direct causes are as follows: 1) road infrastructure development, 2) slashing and burning the forests to transform forest land into agricultural land, 3) the collection of fuelwood and charcoal, and lastly 4) unregulated artisanal and small-scale logging.
The Report examined the rate of decline in biodiversity and found that the adverse effects of human activities on the world's species is "unprecedented in human history": [14] one million species, including 40 percent of amphibians, almost a third of reef-building corals, more than a third of marine mammals, and 10 percent of all insects are ...
Therefore, when environmental conditions change, this can result in changes to biodiversity. [4] The effects of climate change on plant biodiversity can be predicted by using various models, for example bioclimatic models. [5] [6] Habitats may change due to climate change.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
Climate change is likely to favour some invasive species and harm others, [161] but few authors have identified specific consequences of climate change for invasive species. [162] Invasive species and other disturbances have become more common in forests in the last several decades. These tend to be directly or indirectly connected to climate ...
[11] [12] Furthermore, a loss in biodiversity makes it harder for ecosystems to adapt to climate change. [12] With over half the global GDP being dependent on nature and the livelihoods of over 1 billion people worldwide connected to forests, the consequences of biodiversity loss are extensive.
The National Biodiversity Assessment (NBA) is a recurring project by the South African National Biodiversity Institute in collaboration with the government department currently responsible for environmental affairs and several other organisations to assess the state of South Africa's biodiversity over time as an input for policy and decision ...
