The country is mountainous with elevations ranging from 150 up to 8,000 m. traversing south to north with a great diversity of environments. Of the 600,000 population, 90 percent are dependent on agriculture. Farming is essentially subsistence and the main crops grown are maize, rice, millet, buckwheat, barley, and mustard. However, the mountainous nature of the country makes only about 8 percent of the total land suitable for crops (LUPP, 1995). Furthermore land use is dictated by the diverse climate and topography. Land use is shown in Table 1.
