The purpose of this water footprint assessment is to provide Jain Irrigation Systems Ltd (JISL) with a framework to measure and report on the water footprints of its products, assess the potential influence of those footprints on local hydrologic systems, assess potential social and ecological impacts, and identify possible response strategies. Most importantly, this assessment addresses the sustainability of water use throughout JISL's supply chain for dehydrated onion products in the context of physical water scarcity concerns in the local (Tapi river) watershed. The goals of the water footprint assessment are to: measure the volumes of water consumed in JISL's operations and supply chains for micro-irrigation systems (MIS) and dehydrated onions in the Tapi River watershed; assess the sustainability of this water use, particularly at the farm level; identify appropriate response actions to address the outcomes of the sustainability assessment; and document and share publicly through the Water Footprint Network the water footprint assessment results and lessons.
