The occurrence of ravine emergence is recurrent in Angola, but the natural phenomenon has intensified as a consequence of human development and human activity, and the cracks have registered rapid progression throughout the territory, putting at risk housing, commercial and housing infrastructures. public services. Unregulated or unlawful practices related to housing construction along water lines, expansion of the road network, irregular agricultural practice, massive deforestation, burning, overexploitation of ore and obstruction of the drainage system are the causes of the devastating effect ravines have caused in the last decade. In several provinces are recorded multiple reports of residential buildings, commercial buildings and roadways affected or destroyed by the rapid progression of ravines.
In the city of Luena, Moxico province, slits threaten to swallow some public buildings, such as the example of a crater 15m deep and 30m wide that has been extending towards the city’s thermal power station. Also, two of the country’s main roadways run the risk of being impassable. In Malangue there are already 90 kilometers under these conditions and in Zaire province, since last September, the phenomenon has provoked more than 2000 evacuees.
