Dr Prabhakar Sharma has been teaching a number of courses (such as Earth & Environmental Sciences, Environmental Pollution, Environmental Hydrology, Contaminant Hydrology, Waste Management, Emerging Pollutants in the Environment, and Research Methodology) at Nalanda University. Earlier, he served at the Department of Earth Sciences, Uppsala University, Sweden as an Assistant Professor. He was involved in teaching field and groundwater modelling related courses and performed research related to CO2 and nanomaterial transport and retention. He had also worked at University of Western Ontario (Canada) and Ålbog University (Denmark) as a full time researcher and pursued his PhD dissertation from Washington State University (USA).

Teaching and research experience

Dr Prabhakar Sharma had published more than 30 high impact peer-reviewed journal articles, supervised one PhD students and more than 25 Master’s dissertation. He applied various experimental, field, and modelling techniques on studying transport and mobilization of contaminants in soil and water. At Nalanda University, he developed an Environmental Laboratory to investigate nanoparticle transport and mobilization at various physical and chemical conditions of natural soil systems. Nalanda district, which is among the major producer of food grain in the state, is highly dependent on ground water for irrigation purposes but water scarcity and over reliance on groundwater is putting enormous stress on the groundwater aquifers in this region. In order to analyze the technical viability of artificial recharge to overcome the water scarcity issue, he has been preparing a hydro-geological mapping of this region to identify the aquifer characteristics and planning to conduct long term water quality monitoring of the recharged aquifers. Recently, he has received a prestigious grant from Australian Centre for International Agricultural Research to investigate the shallow subsurface mapping through geophysical fluid-logging in order to understand the water fluctuation and its availability for community, application of artificial aquifer recharge, and agriculture practices.

Current Project

Aquifer characterization, artificial recharge and reuse of suddenly available water in South Bihar

ASRA (Aquifer Storage & Recovery for Sustainable Agriculture) is an aquifer recharge project, funded by Australian Centre for International Agricultural Research under the Department of Foreign Affairs and Trade, Government of Australia. The objective of this project is to test a model of aquifer storage and recovery (ASR) technology using seasonal floodwaters in the region of South Bihar -a drought-prone region. This model aims to recharge the subsurface aquifers. The goal of the project is to provide the opportunity to farmers of the region to raise their incomes from agriculture and allied activities, through assured irrigation from the reuse of water stored beneath the surface during draught. The proposed work primarily involves aquifer mapping, assessment of social perception about technology adoption and study of environmental risks emerging due to groundwater depletion.
