Artisanal and small-scale mining in the municipality of Sumbe, Cuanza Sul province, Angola, has been practiced for the past 20 years, by many families in need of economic support and materials to build their homes, causing damage to the environment of diverse magnitude. The objective of this research is to identify and evaluate the environmental impacts produced by arid exploitations through artisanal and small-scale mining in this territory, with emphasis on the detection of the main socio-environmental problems generated by these mining activities and the need to establish a regulatory framework based on the sustainable exploitation of these resources through an environmental management strategy. For this, field methods, survey-interview instruments and methods for the identification, characterization and evaluation of environmental impacts were applied. The results obtained allow to clarify the implications that these mining activities have on sustainable socio-economic development, as well as to denounce the indiscriminate use of women and children, all stimulated by the high demand of extracted materials for civil constructions and the economic benefits that they report immediately. The anarchy and irrationality derived from these actions cause moderate environmental impacts and instability of environmental components. Among the measures that are proposed for the environmental ordering of this type of mining activity are considered: a) the creation of cooperatives; b) the establishment of norms that regulate the granting of artisanal mining concessions, with the elimination of the exploitation of the female and child population; c) the application of environmental education programs to the population; d) the development of control instruments for arids mining; e) the implementation of regulations that declare individual and collective responsibilities for the restoration of the environment within a legal framework.
