Sand winning, or the extraction of sand from natural environments, is primarily driven by demand for construction materials, particularly for concrete and infrastructure development. Rapid urbanization and population growth contribute to increased construction activities, leading to higher sand consumption. Additionally, coastal and riverine sand extraction is often motivated by economic incentives, as sand is a valuable resource for various industries. However, unregulated sand winning can lead to environmental degradation, loss of biodiversity, and increased vulnerability to erosion and flooding.
Sand winning refers to the gathering and carrying away of parts of the solid earth such as sand and gravel as raw material for construction of roads and buildings. The term seems to be restricted to Ghana, in Africa. Other places may refer to it as sand mining. It is the collection of sand. It is often done illegally and causes problems for the environment.
