The undulating land is widely cultivated by subsistence farming. Even wetlands and slopes are reclaimed for farmland resulting in soil erosion and river pollution. The land use is characterized by crop-, livestock -, and fish farming as well as agroforestry. There is also bee keeping, mushroom growing, quarrying and mining. Brick making is a recent activity with high economical value and cotton is the major cash crop. An increased firewood demand and Eucalyptus farming are the main reasons for deforestation.
