Why is fluorosis more toxic for children? What is the link between fluoride and calcium deficiency? These questions and more answered.

Fluorosis is a cowardly disease; it selectively preys upon the most vulnerable and renders them even more fragile. We have discussed earlier how fluoride contamination is especially deadly to the poor of India as they lack the nutrition, the options and the information needed to combat it.

Bone disease fluorosis can be prevented if people understand the importance of good nutrition

Fluorosis is a bone disease that is caused by a high consumption of fluoride. Most think that it is a direct result of drinking water with high fluoride content alone but it isn’t so. Nutrition plays an  important role in the onset of this disease. Including vitamin C and calcium in our diets as well as modifying cooking methods to lessen the absorption of fluoride from cooking water are crucial to preventing fluorosis.

This article presents videos of related talks, short descriptions of each video and links to background papers from the IWMI-Tata Annual Partners' Meet in 2012.

India is the world's largest consumer of groundwater where it is extensively used for irrigation. However, there is a considerable waste of this valuable resource. While a part of this waste can be attributed to a lack of incentive for conservation, unmetered electricity supply contributes greatly to this problem. This has led to the formation of what is being termed an energy-irrigation nexus.

Several sessions at the IWMI-Tata Annual Partners' Meet in 2012 discussed this phenomenon, its causes, impact and possible management strategies.

This paper published in the Economic and Political Weekly highlights the present groundwater situation in the country

It 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.

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.

The groundwater crisis is acquiring alarming proportions in many parts of the country. Strategies to respond to groundwater overuse and deteriorating water quality must be based on a new approach involving typologising the resource problems and redefining the institutional structure governing groundwater.

India’s Groundwater Challenge and the Way Forward

The groundwater crisis is acquiring alarming proportions in many parts of the country. Strategies to respond to groundwater overuse and deteriorating water quality must be based on a new approach involving typologising the resource problems and redefining the institutional structure governing groundwater. This approach is based on the notion of groundwater as common property.

Understanding groundwater hydrology.

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.

The discussion paper deals with groundwater contamination and rural water treatment in Gujarat, as quality problem of this important drinking water source has led to high social costs

carewaterThe 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.

The impacts of groundwater contamination with fluoride and arsenic in India

carewater

The field research study conducted by Carewater INREM Foundation attempts to establish the impacts of groundwater contamination with fluoride and arsenic in India. It maps the affliction severity, the medical cost and wage loss through a multi-location study in some villages in the States of Rajasthan, Andhra Pradesh, Karnataka and West Bengal.

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.

Rural Gujarat's solution for drinking water: Reverse Osmosis technology

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.
