State of vegetation, erosion climatic conditions and re-vegetation technology in Mid Hill area of Nepal

Abstract

Nepal is a mountainous country which is suffering from mass movements and surface erosion annually because of its steep terrain, fragile geology and high rainfall characteristics. The occurrence of shallow depth and translational landslides, gully erosion, bank erosion, surface erosion and flooding are the major erosional problems. In case of Nepal, the constructions of larger hard structures are not affordable due to the poor economic condition and rugged terrain nature. Therefore the use of re-vegetation technology is the cheapest and easy method for erosion control. Due to climatic variations the common hazards and vegetation types in each zone also differs. It is necessary to identify the suitable plant species and re-vegetation technology that can be used for erosion mitigation in Mid Hill region.
