Evaluation of sustainability of groundwater resources in a semi-arid region of the Maharashtra State of India

This study aims to assess the sustainability of groundwater resources in a semi-arid watershed in the Maharashtra State of India using sustainability indicators proposed by the United Nations Organization for Education, Science and Culture (UNESCO). We have selected seven widely used indicators based on their relevance in the field of groundwater sustainability and proven data collection reliability and methodology. These indicators were applied to a Dhubdhubhi watershed with a semi-arid climate. The integral application of all these indicators in this particular watershed leads us to conclude that at present the groundwater resources of the entire watershed is at a stage requiring sustainable development. However, in some areas groundwater development and use is semi-critical and over-exploited, which may result in a critical situation unless adequate management practices are put in place.   Key words: Groundwater sustainability, semi-arid region, indicators, India.
