Research Interests : Soil Erosion and Watershed Management

Desertification, land degradation and drought affect one-third of the earth’s dryland surface. The situation might worsen due to the unsustainable use of soil and water under present scenarios of climate change and population growth. Degradation of water, soil and vegetation, as well as gas emissions can be limited by sustainable land management practices (SLM) that simultaneously conserve natural resources and increase agricultural productivity. Many SLM practices have been documented but there is a great need to clarify their impact in different contexts and to adapt and optimize them under different conditions. Moreover, additional new technologies need to be developed.Therefore the general aim of my research is to contribute for the realization of SDGs-15.3 “By 2030, achieve a land degradation-neutral world” by understanding landscape sensitivity to external forces of change and developing appropriate SLM practices through education and research. The research employs integrated approach comprising of field and laboratory experimentation and monitoring; field survey and mapping; socioeconomic surveys; scenarios formulation for climate, land use and population growth; spatial analyses and hydrologic and erosion modelling for selected regions of the world.
