Abstract

Anthropogenic action has caused intense changes in land use and cover over the decades. Identifying and knowing these changes makes it possible to measure the impacts that can be generated as well as to identify patterns of the development of a particular region and the relationship between society and land use. Thus, it is intended to identify the changes made in the land use and occupation of the Mucuri river basin between 1989 and 2015. So, this study used remote sensing techniques and tools besides aerial photographs to map the region and to identify surface behavior. Within the Mucuri basin, the soil had been mostly occupied by classes of forest and agricultural area, consistent with the social and economic reality of the region over the last decades. The changes that have occurred indicate a reduction in water availability, growth in urban occupation and, in many cases, soil and vegetation cover deterioration.

Summary

Introduction

The impacts on the environment caused by the man have intensified over the years. Such actions are related to social dynamics and economic development, leading to constant changes in the earth’s surface. The study of land use and occupation aims to understand the environment and the distribution of its various forms, such as vegetation removal, urban construction, preservation areas, farming and other activities (VAEZA et al, 2010). It is extremely important to study land use and occupation as a basis for environmental management projects, practices of zoning and other procedures that require a knowledge of the area of interest. There is a need for technologies that allow locating and monitoring such issues, so more environmentally friendly and sustainable practices with lower impact in environment are adopted
