Anthropic action in food production in Brejos de Altitude areas in the semiarid region of the Northeast, Brazil ; Ação antrópica na produção de alimentos em áreas de Brejos de Altitude no semiárido do Nordeste, Brasil

The high-altitude wetlands are peculiar biogeographic units because they are a set of wet forest areas surrounded by typical Caatinga xerophytic vegetation. The objective of this work was to observe the influence of environmental changes on the production of traditional crops in the municipality of Garanhuns, using pluviometric data extracted from APAC and the IBGE database, as well as satellite images. In total, historical series of rain, agricultural production and land use data were collected for the municipality of Garanhuns and translated using the QGIS and excel program for the creation of relationship figures and graphs. It was observed that natural forest areas were reduced from 5% to less than 1% over a period of 15 years, and that traditional productions such as cattle raising, cassava planting, corn and beans are in decline. This is linked to climate change and the processes of soil and vegetation degradation in the region. It has also been observed that new crops are on the rise, such as the production of poultry confined to farms, the production of pigs and goats, as well as crops such as bee honey and fish farming. Thus, man-made changes in the environment are relevant in the process of environmental imbalance and loss of biodiversity of a region. ; Os brejos de altitude são unidades biogeográficas peculiares pois são um conjunto de áreas de florestas úmidas rodeadas por vegetação xerófila típica de Caatinga.
