The total area of Nepal 1,47,181 sq.km. out of which the use of land under agriculture is 26.5 percent, under forest 42.4 percent, under grazing field 11.8 percent and under other sectors it is 19.3 percent. Nepal can be divided into plains, valleys, rivers, river basins hills, low valley's slopes and Himalayan ranges as per the level of land. The average size of land holding per tenant is reducing due to human activities and the area of average cultivated land is also declining. With the growth population, pressure on land is immensely incresased. This pressure is drastically high in Terai region. The need of land has increased for foodgrains, settlements and other requirements to the growing population. it has increased natural calamities like soil erosion, land slides and floods. Dolpa and Mustang districts have been converted into desert. The land has been divided into small pieces. So, the modernisation of agriculture has been most difficult. There is irregularity of rain. The alluvial soil is flowing every year by the flood.
