Deforestation in the United States was affected by many factors. One such factor was the effect, whether positive or negative, that the logging industry has on forests in the country. Logging in the United States is a hotly debated topic as groups who either support or oppose logging argue over its benefits and negative effects.
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 ...
Several studies since the early 1990s [30] have shown that large-scale deforestation north of 50°N leads to overall net global cooling [31] while tropical deforestation produces substantial warming. Carbon-centric metrics are inadequate because biophysical mechanisms other than CO 2 impacts are important, especially the much higher albedo of ...
However, massive deforestation for economic development threatens its forests and ecosystems. As of 2015, the country has one of the highest rates of deforestation in the world. [47] Deforestation has directly resulted from poorly managed commercial logging, fuel wood collection, agricultural invasion, and infrastructure and urban development.
Since 1990, it is estimated that some 420 million hectares of forest have been lost through conversion to other land uses, although the rate of deforestation has decreased over the past three decades. Between 2015 and 2020, the rate of deforestation was estimated at 10 million hectares per year, down from 16 million hectares per year in the 1990s.
Short-term economic gains made by conversion of forest to agriculture, or overexploitation of wood products, typically leads to loss of long-term income and long term biological productivity. West Africa , Madagascar , Southeast Asia and many other regions have experienced lower revenue because of overexploitation and the consequent declining ...
Forest recovery resulting in net increases in forest extent can occur by means of spontaneous regeneration, active planting, or both. [11] [12]There are two main paths in reforestation, one emerging from economic development and another from forest scarcity. [12]
The Kyoto Protocol article 3.3 thus requires mandatory LULUCF accounting for afforestation (no forest for last 50 years), reforestation (no forest on 31 December 1989) and deforestation, as well as (in the first commitment period) under article 3.4 voluntary accounting for cropland management, grazing land management, revegetation and forest ...
