Abstract

Currently it is noted in Angola that there has been a considerable reduction and degradation of forest both in Miombo and in other native forest formations in the country. The record of high rates of deforestation has led the researchers to compare the forest changes cover in Cuima communes in a comparative way. (municipality of Caála) and Chipeio (municipality of Ecunha), both belonging to the province of Huambo, between 2009 and 2019, based on remote sensing data from Global Forest Watch. The two study zones, which both fall within the agricultural region 24 of the country, were the blocks subjected to vegetation dynamics analysis on the Global Forest Watch platform. In this stage, the following variables were analyzed: annual forest area, loss of annual forest area and gain of annual forest area of each commune. Geospatial data were also obtained from the Maplibrary, Earth Explorer and Copernicus Open Access Hub servers. The results point to a reduction of 12.7% in the forest area of the municipality of Cuima and 6.6% in Chipeio, between 2009 and 2019. There was also evidence of a low rate of gain in forest area and a high rate of loss of forest cover; for this reason, if there are no interventions, it is expected to see a reduction in the period 2009 and 2030 from 60.5% to 39.2% in the municipality of Cuima and from 88.1 to 74% in Chipeio. The adoption and promotion of alternative sources of family income are identified as the means of sustaining the studied forest resources.
