Title A name given to the resource Análise Multitemporal do Uso e Cobertura da Terra da Bacia Hidrográfica do Alto Rio Jardim, Planaltina-DF (Multi-temporal analysis of land use and cover in the Alto Rio Jardim Watershed, Planaltina-DF, Brazil) Creator An entity primarily responsible for making the resource Carlos Henrique Nonato Vieira, Luciano Mansor de Mattos, Juaci Vitória Malaquias, Fabiana de Gois Aquino, Patrick Thomaz de Aquino Martins Description An account of the resource O monitoramento do Cerrado e dos recursos naturais nele presente é de importância para a preservação e conservação da biodiversidade e da qualidade de vida das populações, uma vez que, nas últimas décadas, o Cerrado vem passando por um intenso processo de mudança do uso da terra, com sua cobertura natural sendo convertida em áreas antropizadas. O presente estudo tem como objetivo analisar a dinâmica da paisagem, no decorrer das últimas três décadas, na Bacia Experimental do Alto Rio Jardim (BEARJ), Região Administrativa de Planaltina, Distrito Federal. Com aproximadamente 10.500 Ha e de ocupação predominante voltada para atividades agropecuárias, a bacia se destaca pela produção de grãos. Foram utilizadas imagens do programa Landsat, resultando no mapeamento multitemporal dos anos de 1985, 2000, 2010, 2015, o qual foi complementado pelo banco de dados do Projeto Ecovaloração (Embrapa Cerrados), que permitiu a espacialização e análise de informações relacionadas à categoria produtiva e origem do líder familiar das Unidades de Produção. Foi possível notar que a BEARJ está passando por mudanças no uso da terra, ficando evidente uma leve queda na cobertura vegetal natural nos primeiros anos de análise, sendo que essa classe passou por uma transformação mais intensa no período anterior a 1985, se mantendo próximo ao limite legal nos anos posteriores a 2000, de acordo com o código florestal anterior. Nesse caso, as mudanças mais significativas correspondem à conversão das pastagens para as culturas anuais até 2015.       A B S T R A C T The monitoring of the Cerrado and its natural resources is important for the preservation and conservation of biodiversity and the quality of life to the populations from Midwest Brazilion. Since in the last decades, it has undergone an intense process of land use change, with its forest cover being converted to anthropized areas. The aim of this study is to analyze the dynamics of the landscape during the last three decades in the Alto Rio Jardim Watershed (BHARJ), Administrative Region of Planaltina, Federal District. With approximately 10,500 Ha and predominant occupation oriented to agricultural activities, the basin is inserted in the Tabatinga Rural Nucleus, and stands out due to the production of grains. It is also a space for a diversified production of vegetables, fruits and livestock. Geotechnology tools were used as methodological procedures for the treatment and interpretation of the georeferenced data, allowing the multitemporal mapping of the years 1985, 2000, 2010, 2015. This methodology was complemented by the database of the “Ecoevaluation” and “Productive Transition and Environmental Services” Projects (Embrapa Cerrados), which allowed the spatialization and analysis of information related to the productive category and cultural aspects related to the origin of the families residing in the production units. It was possible to observe that the BHARJ is undergoing changes in the land use, with slight fall in the natural forest cover in the first years of analysis, and more intense transformation in the previous period to 1985, remaining close to the legal limit in the years after 2000. In this case, the most significant changes correspond to the conversion of pastures to annual crops by 2015.
