Theme: THE DEGRADATION OF WETLANDS AND ITS SOCIO ECONOMIC AND ENVIRONMENTAL IMPLICATIONS IN NDOP CENTRAL SUBDIVISION, NORTH WEST PROVINCE CAMEROON

Bamessing. (see figure 3) The transition from highland to lowland in some areas is gentle but in most cases it is an abrupt quasi-crisp boundary between highland and lowland.    
            This area is mostly constituted of colluvial and alluvial soils (Hawkins P & Brunts, 1965). Colluvial soils are dominant in the dryer regions meanwhile alluvial soils are dominant in the flood plains. Due to the creation of the Bamendjin dam, there has been an intense deposition of alluvial soils in Bambalang. Some areas equally tend clayish and this is responsible for the impemeability of soils in the wetlands. Hence these soils are most often hydromorphic in nature.
Besides the altitude and soil of this region, the climate also accounts for the presence of these wetlands. Ndop Central Subdivision like most parts of west Cameroon is characterised by two seasons, i.e. the rainy season and the dry season. The rainy season lasts for over 8months meanwhile the dry season lasts for over 4months (Suchel.J. 1972). The climate varies only slightly within the various villages of Ndop Central Subdivision (see figure 4).
