Ninety percent of Africa's population requires wood to use as fuel for heating and cooking. As a result, forested areas are decreasing daily, as for example, in the region of equatorial evergreen forests. According to the United Nations Environment Programme, Africa's desertification rate is twice that of the world's. [4] Deforestation of ...
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.
Example of human caused habitat destruction likely capable of reversing if further disturbance is halted. Uganda. Natural vegetation along this coastal shoreline in North Carolina, US, is being used to reduce the effects of shoreline erosion while providing other benefits to the natural ecosystem and the human community.
The land use change and sea use change was considered the most important stressor, followed by direct exploitation of organisms (i.e. overfishing). Climate change ranked third, followed by pollution and invasive species. The report concluded that global warming of 2 °C (3.6 °F) over the preindustrial levels would threaten an estimated 5% of ...
Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent. It is temporary if the damage that led to the loss is reversible in time, for example through ecological restoration. If this is not possible, then the decrease is permanent.
For example, climate change can cause species to move in different directions, potentially disrupting their interactions with each other. [10] [11] Examples of effects on some biome types are provided in the following. [clarification needed] [where?] Research into desertification is complex, and there is no single metric which can define all ...
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.
Ecosystem-based Adaptation (EbA) describes a variety of approaches for adapting to climate change, all of which involve the management of ecosystems to reduce the vulnerability of human communities to the impacts of climate change such as storm and flood damage to physical assets, coastal erosion, salinisation of freshwater resources, and loss of agricultural productivity.
