Para uma análise da degradação da floresta de mangal: o caso de Nhangau

Abstract

Summary The use and conservation of natural resources requires a prior and accurate assessment of the availability of natural resources. The evaluation of natural resources involves the use of appropriate techniques and methods that allow analyzing the use of mangroves in the Nhangau area, Sofala province, and aims to highlight the scarcity of flabby data on natural resources in small areas. A case study was carried out in the Nhangau area to assess the dimensions and factors of mangrove forest degradation, mangrove tree felling rates, types of mangrove use, to analyze the implications of mangrove forest degradation in the coastal ecosystem and agricultural activity. Data on the mangrove area, mangrove species, types of use and factors influencing mangrove forest degradation were obtained through the application of the cartographic method, geographical comparative method and field observation. Finally, the work analyzes the maps (source of cartographic information) used and proposes relevant considerations for the analysis of natural resources.
