RESUMO:

The concept of ecosystem services entered the political agenda and began tobe released after the Millennium Ecosystem Assessment report in2003. This concept differentiates ecosystem services in support,provision, regulation and culture. The literature that deals with the concept of servicesecosystems has gained strength in the academic process, involving science andpolicy, to encourage the conservation of nature with the concern ofbiodiversity loss. The Amazon rainforest supports resourcesnatural resources essential for life, and their conservation is necessary for themaintenance of biodiversity and ecosystem services. areas ofLegal Reserve and Permanent Preservation Areas play a roleimportant in the preservation of biodiversity and are providers of servicessupport ecosystem services, such as maintaining the supply of potable water,supply of wood and habitat for the diversity of fauna and flora. However, thevegetation change in the Amazon rainforest causes irreversible loss ofecosystem services from fauna and flora biodiversity, changes climate andlocal atmospheric humidity, generates carbon loss and change in cycle flowhydrological. In this sense, worrying about the temporal situation of lossof vegetation and, consequently, the trade-offs of ecosystem services,This research aims to analyze the impacts of use and occupation ofland in the process of agricultural expansion on ecosystem services ofsupport provided by the vegetation of the Amazon Forest, in the period of 1990to 2020, in Sinop and Alta Floresta (MT). In the municipalities analyzed, there wasreduction of vegetation in all phytoecological categories: in Sinop,40.54% with an area of 165,771 hectares; in Alta Floresta, 50.6% with aarea of 452,808 hectares. Compared to the year 1990, starting pointof the previous period of investigation, Sinop counted 62,340 hectares and AltaForest 166,405 hectares. While the monoculture in Sinop represented67% of the occupation of the territory, in Alta Floresta, livestock was responsible for30% of the transformation of the native vegetation area. The analyzes in the area ofLegal Reserve (RL) and Permanent Preservation Area (APP) showed thatlower reflectance occurred in the biomass in the year 2020: the NDVI was between 0.2 and0.3, compared to the year 1990, the starting point of the investigation. Usother period – 2000, 2010 –, the NDVI was in the range of 0.4 to 0.8 in boththe municipalities. In Sinop, the need to recover the riparian forest areais 1,821 hectares and in Alta Floresta it is 15,304 hectares. Still, there is a deficit126,300 hectares of RL in Sinop; in Alta Floresta, of 228,000 hectares. Oaccumulated deforested area sum of the two municipalities in 2020 in the RLin large properties it is 65,636 hectares, in medium properties it is49,069 hectares and in small properties it is 11,617 hectares.We conclude that the proposed methodology allowed an analysis of theenvironmental conditions of the vegetation in RL and APP Areas, whichplay an important role in preserving biodiversity and areproviders of ecosystem support services in natural habitat, offerof water, soil moisture and CO 2 concentration in the municipalities of Sinop andHigh Forest.
