Vaibhav Chaturvedi from CEEW presents a seminar at Energy- Water nexus at the Potsdam Institute for Climate Impact Research (PIK)
27 Nov 2013

Dr. Vaibhav Chaturvedi presented an overview on the research landscape in India on the issue of food-energy-water nexus at PIK. Vaibhav began the presentation by highlighting that the key driver for the discussion of energy-water nexus for India is the fact that India is a water stressed nation, and limited development of surface water sources has lead to a huge pressure on India's groundwater resources. The presentation then discussed three key themes of the energy water research landscape for India. The first theme was irrigation-energy nexus. Dr. Chaturvedi highlighted that this is an area in which researchers from India have been doing research for some time, and so there exists a knowledge base.Irrigation water is a common property resource issue and that is how it has been addressed in terms of research. Distorted market subsidies  for electricity inducing wrong incentives for farmers are widespread in India leading to excess extraction of groundwater as well as inefficient use of energy. The next two themes related to electricity water nexus and bioenergy-climate -water nexus are themes that haven't been explored and research in India is in very initial stages on these issues. Dr. Chaturvedi highlighted that the technologies that the Indian government is pursuing, mainly nuclear and solar, are associated with much larger withdrawal of water compared to conventional thermal technologies. The carbon capture technology, which might play an important role in the long run future under a climate constrained world, consumes double the water compared to a non-CCS thermal power plant. Also, though India is not expected to be a big bioenergy producer in the future, the marginal impact bioenergy can potentially have in terms of water demands as well as on land use dynamics for food crop production is not going to be insignificant. The discussion with PIK modeling team finally browsed on issues related to representing the nexus in global energy modeling frameworks and the associated data and analytical challenges.
