India’s groundwater challenge and the way forward - Economic and Political Weekly

This paper published in the Economic and Political Weekly highlights the present groundwater situation in the country and warns that groundwater quantity as well as quality are the two major problems that the country has been facing.

The rate of withdrawal of groundwater has reached “unsafe” levels in 31% of the districts, covering 33% of the land area and 35% of the population. The situation has dramatically worsened within a short span of nine years, between the assessments done in 1995 and 2004.Read More

Taking the quantitative and qualitative aspects together, data indicates that a total of 347 districts (59% of all districts in India) are vulnerable in terms of safe drinking water in India. This is a matter of serious concern, requiring a new approach.

An illustrated collection of groundwater problems: A guide to a beginner in groundwater hydrology by CAREWATER

This report by CAREWATER has been prepared as part of a component on Groundwater Governance in Asia: Theory and Practice under the CGIAR Challenge Programme on Water and Food. The purpose of this collection is to guide a beginner to groundwater hydrology through the basic concepts in this subject. The problems begin with fundamentals of the subject and are followed by those which test the comprehensiveness of understanding. Most problems are illustrated and a real-world situation is related with the problem.Read More

Groundwater contamination and rural water treatment in Gujarat: A discussion paper by CAREWATER

carewaterThis discussion paper by Carewater INREM Foundation deals with groundwater contamination and rural water treatment in Gujarat. The State is characterized by varied hydrogeology and vast areas are faced with typical groundwater quality problems like fluoride. Much of the coastal groundwater is saline while the alluvial tract is marked with inland salinity.Read More

The living wisdom: Using local well driller knowledge to construct digital groundwater data bases – A report by CAREWATER

carewaterThe report by Carewater INREM Foundation draws inferences from studies across the Indo-Gangetic Basin on using local well driller knowledge to construct digital groundwater databases. The low density of current groundwater instrumentation networks in the region is both cost and management intensive, contrary to local knowledge, which has greater spatial coverage and can be obtained at a relatively lower cost. An efficient way to tap such local groundwater knowledge is through well drillers. Read More

Reverse Osmosis plants for rural water treatment in Gujarat - A study by CAREWATER

carewaterThe report by Carewater INREM Foundation deals with Reverse Osmosis (RO) technology, which is emerging as an important solution for drinking water treatment in rural Gujarat. RO plants with capacity ranging from 10 litres per hour (lph) to 6000 lph are now supplying drinking water in several hundred villages of the State. Small sized plants with capacity < 20 lph are used by individual families whereas medium to large sized plants (>100 lph) are being used for public consumption.Read More

Groundwater and well water quality in alluvial aquifer of Central Gujarat - A paper by CAREWATER

carewaterThe report by Carewater INREM Foundation deals with groundwater and well water quality in the alluvial aquifers of Central Gujarat. Gujarat has a hydrogeology representative of almost all aquifer types and depositional & formation eras. Contamination of aquifers along with scarcity of groundwater resources due to increase in water demand and reduction in recharge of groundwater from changing landuse, is a problem in Central Gujarat.Read More

Possibility of revival of dug wells in hard rock India through recharge: A discussion paper by CAREWATER

carewaterThe discussion paper by Carewater INREM Foundation on possibility of revival of dug wells in hard rock India through recharge is based on a field study across ten districts of the country. The study seeks to understand how localized governance of groundwater in hard rock areas is to be pursued through pricing (water, energy), legal regulation and community institutions. Water supply augmentation and demand management are both to be taken care of, directly through regulation or through indirect instruments such as pricing.Read More

Duel among duals - Popular science of basaltic hydrogeology in a village of Saurashtra - A paper by CAREWATER

Carewater INREM FoundationThe report by Carewater INREM Foundation deals with the duel between popular science used in decision making by farmers and the formal science of hydrogeology that is based on scientific data collection. These two parallel streams of knowledge exist together, sometimes complement, and at other times are at conflict. People’s knowledge on hydrology is not ‘dying’, but thriving and growing well, refreshed continually by interfaces with science. In hard rock areas, the high hydrogeologic variability makes observation as important as theory since it is localized, pervasive and relevant to the needs of people.Read More
