Abstract

Geologically young and tectonically active Himalayan Range is characterized by highly elevated mountains and deep river valleys. The mountainous terrains of Nepal Himalaya are characterized by dynamic physical processes, and therefore, mitigation of geo-disaster is a big challenge. A better understanding of the geological nature of the terrain and the interaction of various triggering factors of geo-disaster will greatly help in the development of safer infrastructures, mitigation of geo-disaster, and control of land degradation in the Himalaya. Over the years, Nepal has gained a significant amount of experiences in geo-disaster studies, especially in design and survey of geo-disaster mitigation programs, in the fields of hazard and risk assessment, in low cost rural road engineering; in community based river training work and in slope maintenance incorporating indigenous techniques. This chapter provides an overview of geo-disasters in Nepal and their mitigation efforts. In this chapter, all geological zones of Nepal are evaluated from the perspective of geo-disaster occurrences. Geo-disaster mitigation efforts of both governmental and non-governmental sectors are also evaluated. People’s perception for geo-disaster mitigations efforts are also discussed in this chapter.
