Desmatamento na Amazônia Brasileira: Com que intensidade vem ocorrendo?

Abstract: ResumoO desmatamento na Amazônia brasileira está ocorrendo a uma taxa inédita. Uma série de imagens de satélite LANDSAT de áreas de colonização em Rondô-nia, de 1973Rondô-nia, de até 1978 A não homogeneidade das taxas de desmatamento resultaria em que algumas áreas seriam desmatadas mais cedo e outras, mais tarde; se as taxas de desrr.a tamento permanecessem constantes, dentro de cada Estado ou Território, estes seriam desmatados em datas que variam desde 1988 para Rondônia até 2159 para Amapá.

“…OLS using a linear or quadratic trend) lead to more unexplained variations of the deforestation rate. The initial 1975 deforested area appears small compared to later years, but the PRODES data match quite well independent estimates by Skole and Tucker [31] and is also consistent with Fearnside (1982) [14] early assessment. The 1995 peak was attributed to accidental forest fires [22].…”

“…It is also worth noting that the Lag one period of Deforestation is included in the VECM representation; when it is included in an OLS estimator of the EKC relation (2), it is largely insignificant. Although not the same as Granger causality, 14 that supports the idea that the observed significance levels are not spurious. Graphically, the fitted deforestation is presented in Figure (2).…”

“…Uncontrolled deforestation and colonization in the Amazon are currently amongst the great concerns of (thinking) citizens in our country, and give rise to great international speculation regarding the possibility of exponential increase in these activities (Fearnside 1982) . Several studies on the matter have been carried out recently and will not be discussed here due to lack of space.…”

“…In Figure 10e it is also interesting to note the symmetric and complementary pattern of burned areas over pasture and remnant vegetation, suggesting that years of intensive pasture use correspond to lower pressure over the natural vegetation. Such trends and patterns take place mostly at the transition zone with the Cerrado biome (i.e., the Arc of Deforestation), characterized by intense anthropic occupation [48,[68][69][70][71][72][73]. In relation to the Atlantic Forest (Figure 9(c)), it is noteworthy the well distributed occurrence of burned areas over the remnant vegetation (35% or 9,617 km 2 ), pastures (25% or 6,651 km 2 ), and agricultural fields (39% or 10,553 km 2 ), as the sugarcane plantations, mostly found in this biome, still use fire to assist in the harvest [17,[74][75][76].…”
