APLICAÇÃO DE GEOTECNOLOGIAS NA DINÂMICA DE USO E OCUPAÇÃO AGRÍCOLA NO MUNICÍPIO NOVA CANAÃ DO NORTE – MT

Abstract

The municipality of Nova Canaã do Norte MT has been presenting a great agricultural and cattle expansion over the last years, due to its strong agricultural ability. However, lack of planning and inadequate land use and occupation can damage natural resources, such as: deforestation, soil erosion, silting up of rivers and reservoirs, among others. Therefore, monitoring the use and occupation of the soil becomes essential to the prevention and maintenance of these problems. The objective of this work was the mapping and analysis of the land use and land cover of the municipality of Nova Canaã do Norte MT in the years 1990, 2000, 2008, 2010 and 2017. The land use and land cover mapping was performed by analyzing images of the satellites SPOT-5 and LANDSAT-5 and 8, manipulated by the ArcGis 10.1 software of the respective years studied. In the first two years of study, the native forest areas decreased considerably, giving space to pasture areas. In the year 2000, agriculture appears modestly and gains space in the next years, taking over the old pasture areas. It can be concluded that between 2010 and 2017 the area of native forest declined slightly, showing that the open areas are being intensified and that there is practically no opening of new areas for livestock or agriculture.
