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

Based on the formula, the force of interaction existing between some areas in the region were calculated and presented as seen on figure 11.

With an increase in the population of this area, several anthropogenic activities followed; some going a long way to increase the polarising force this region has on its neighbours. Movements into this area come from as far as the west province and Mezam division. The increase in such movements and hence people have been generally responsible for the degradation of wetlands in Ndop Central Subdivision. These factors will be singled out in the following section.

2.2.1.1. Food crop cultivation and its associated practices.

With an increase in the population of this region, there was a rising need for cultivable lands. Areas located in the higher and dryer altitudes were all cultivated due to their easy accessibility. Later, as the years went by, an increasing demand for food crops led to an increase in cultivable lands at the expense of wetlands. Several areas occupied by wetlands were cleared of their vegetation and drained through irrigation techniques. This led to wetland loss in several areas; meanwhile some areas maintained their wet characteristics but had very
