Deforestation is defined as the conversion of forest to other land uses (regardless of whether it is human-induced). [14] Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period. Net change, therefore, can be positive or ...
English: In this paper we afford a quantitative analysis of the sustainability of current world population growth in relation to the parallel deforestation process adopting a statistical point of view. We consider a simplified model based on a stochastic growth process driven by a continuous time random walk, which depicts the technological ...
The main cause of deforestation in the East African country of Ethiopia is a growing population and subsequent higher demand for agriculture, livestock production, and biofuel. [22] Other reasons include low education and inactivity from the government, [ 23 ] although the current government has taken some steps to tackle deforestation. [ 24 ]
The assessment showed that although the rate of deforestation has slowed, the world's forest area continues to decrease. [16] Key findings include: The world has a total forest area of 4.06 billion hectares (ha), which is 31 percent of the total land area. The world's forest area is decreasing, but the rate of loss has declined since 1990.
Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. [4] [5] Greenhouse gases are emitted from deforestation during the burning of forest biomass and decomposition of remaining plant material and soil carbon.
Roughly 80 percent of the world's forest area is found in patches larger than 1 million hectares (2.5 million acres). The remaining 20 percent is located in more than 34 million patches around the world – the vast majority less than 1,000 hectares (2,500 acres) in size. [9]

One result is that shifting cultivation is not the primary cause of deforestation in all world regions, while transport extension (including the construction of new roads) is the largest single proximate factor responsible for deforestation. [19] Habitat size and numbers of species are systematically related.
