But in the last decade, the majority of observatory wells recorded an average annual decline of half a meter. Groundwater is a common-pool resource that is vulnerable to exploitation, at both individual and community level, and India is its largest extractor. The present system of groundwater management does not enable democratic cooperation between states and the centre for tackling the challenge of overexploitation. In such a context, a decentralised, grassroots level approach to groundwater challenge is essential for equitable, hyperlocal groundwater management. As part of an ongoing study at the Indian Institute for Human Settlements IIHS , we visited five locations in Kerala coastal regions in Ernakulam and hinterlands of Thrissur in February , to understand the efficacy and differential impact of two grassroots techniques: the Rainwater Syringe Technique developed by KJ Antojy, and the Mazhapolima well recharge programme.
The Institutional Dimensions of Groundwater Recharge: A Special Collection
Managed aquifer recharge in California | American Geosciences Institute
Show all documents The maximum annual rainfall recorded was Since then, rainfall was gradually decreasing for consecutive three years, but in , the annual rainfall increased by The results show that Godagari Upazila received the highest rainfall Among the three upazilas Puthia received the low intensity rainfall around all the years relative to Godagari and Paba. The average rainfall received in Puthia Upazila. Water plays an important role in development of agricultural facilities in all parts of the world.

Artificial groundwater recharge plays a vital role in sustainable management of groundwater resources. The present study was carried out to identify the artificial groundwater recharge zones in Bist Doab basin of Indian Punjab using remote sensing and geographical information system GIS for augmenting groundwater resources. The study area has been facing severe water scarcity due to intensive agriculture for the past few years.
We are quite excited about the special collection. It was exciting to put the collection together both because of how we did it and what we found. Our team worked directly with water policy-makers and practitioners to anchor the case studies in the on-the-ground realities of this emerging area of water management. Participants in the case studies, along with other experts, then joined us for a major symposium we hosted on the topic, adding more depth of understanding to the analysis of each case and the collection overall. Participant comments and contributions also reinforced to us that institutions and incentives constitute a key bottleneck for both scholarly understanding of MAR and for its implementation in practice.
