| Abstract |
The problem of ravines negatively affects the development of people’s lives, infrastructure, access
roads, and arable land. The Ravines in Angola became a national security problem putting at
risk buildings, connections of provinces and municipalities, schools, hospitals, residences, water
supply systems, electrical installation even silting up rivers. Large, cultivated areas can become
unproductive, without access roads and economically viable infrastructure for the development of
society, if there is no adequate strategic planning, that considers the particularities of the physical
and biological environment, the social and economic conditions of the development trends of the
region and erosion is not controlled at tolerable levels so that the soils and biodiversity are healthy. |
