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 ...
Deforestation in the Maranhão state, Brazil, in July 2016. The Amazon rainforest, spanning an area of 3,000,000 km 2 (1,200,000 sq mi), is the world's largest rainforest. It encompasses the largest and most biodiverse tropical rainforest on the planet, representing over half of all rainforests.
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.
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 report. [152] This rise in deforestation is occurring amidst the influence of a strong El Niño weather phenomenon, causing dry and hot conditions that have led to droughts and fires throughout ...
The main cause is the decline in deforestation rate in Brazil, due to the government's policies, while Columbia, Peru and Bolivia also reduced deforestation. [ 119 ] In January 2024 published data showed a 50% decline in deforestation rate in the Amazon rainforest and 43% rise in vegetation loss in the neighbor Cerrado during the year of 2023 ...
Carbon emissions from deforestation is an important issue to look at with the increasing problem of global warming.Currently, about 4% of B.C.′s total green house gas (GHG) yearly emissions are from deforestation, which is quite a low percentage compared to B.C.'s total GHG emissions, and works out to be about 6,200 hectares of forest land is converted to non-forest use per year.

Deforestation of the Highland Plateau has led to extensive siltation and unstable flows of western rivers. Like many habitats that undergo deforestation, Madagascar experiences soil erosion, of which can adversely affect river systems and lakes. In the case of Lake Alaotra in Ambatondrazaka area, in the country's east, deforestation in the ...
The large environmental impact of agriculture – such as its greenhouse gas emissions, soil degradation, deforestation and pollinator decline effects – make the food system a critical set of processes that need to be addressed for climate change mitigation and a stable healthy environment.
