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 ...
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.
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 ...
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.
Logging — Clearcutting • Deforestation • Illegal logging Mining — Acid mine drainage • Environmental impact of hydraulic fracturing • Mountaintop removal mining • Slurry impoundments Water (depletion) — Anoxic waters • Aral Sea • California Water Wars • Dead Sea • Lake Chad • Water scarcity
This has a profound ecological impact in that Colombia is extremely rich in biodiversity, with 10% of the world's species, making it the second most biologically diverse country on Earth. [ 151 ] In 2024, deforestation in Colombia's Amazon region has increased by 40% during the first quarter compared to the same period last year, according to a ...
Deforestation has numerous impacts on soil erosion, including: Loss of vegetal cover due to deforestation Loss of vegetation cover: When trees are cut down, the vegetation cover that protects the soil from flooding wind, and other erosive forces is lost. [7] This exposes the soil to the atmospheric elements and makes it more susceptible to ...
Deforestation in tropical areas accounts for an estimated 10 percent of manmade CO 2 emissions, and is a driver toward dangerous climate change. [46] Habitat destruction, leading to the demise of critically endangered species (e.g. the Sumatran elephant, Sumatran tiger, [47] the Sumatran rhinoceros, [48] and the Sumatran orangutan). [44] [49 ...
