Remote sensing and census based assessment and scope for improvement of rice and wheat water productivity in the Indo-Gangetic basin - A working paper by Challenge Program on Water and Food
This paper by the Challenge Programme for Water and Food (CPWF) presents a simplified approach to combine remote sensing, census and weather data to analyze basin rice and wheat water productivity (WP) in Indo-Gangetic river basin, South Asia. It presents an innovative approach to combine meteorological data, ground survey, national census with remotely sensed imagery to assess water use, yield, and finally crop water productivity for the Indo-Gangetic rice-wheat cropping system in South Asia.

Assessing and improving water productivity in conservation agriculture systems in the Indus-Gangetic basin – A working paper by Challenge Program on Water and Food
The paper by Challenge Programme on Water and Food (CPWF) attempts to assess and improve water productivity in conservation agriculture systems in the Indus-Gangetic basin, in which during the past 40 years an intricate mosaic of interactions between man & nature, poverty & prosperity and problems & possibilities has emerged. Rapid expansion in agricultural water use is a common theme across these interactions and access to water is central to the livelihoods of the rural poor.

Water, climate change and adaptation: Focus on the Ganges river basin - A working paper by Challenge Program on Water and Food
This working paper by the Challenge Program for Water and Food explores the intersection between water management, climate change, and adaptation in the Ganges River system, a basin vital to the security, economy, and environment of South Asia.  Recognizing that an understanding of both the science and the policy of water management, climate change, and adaptation is rapidly evolving, it is not the intention of the paper to encompass all the issues related to these broad fields, but rather to provide a starting framework from which to further develop research questions and priorities for work in water and adaptation.

Impact of climate change on water resources and glacier melt and potential adaptations for Indian agriculture - A working paper by Challenge Program on Water and Food
The paper by the Challenge Program on Water and Food deals with the impact of climate change on water resources & glacier melt and potential adaptations in Indian agriculture. Global climatic changes will have major effects on precipitation, water availability, glacier/ice melt, and sea level rise. Climate-induced changes in hydrological conditions will affect the magnitude, frequency, and damage costs of future extreme events.

Is irrigation water free? A reality check in the Indo-Gangetic Basin – A working paper by the Challenge Program on Water and Food
The paper generated under the Challenge Program for Water and Food (CPWF) project explores in some depth a totally different dynamic in the irrigation economy of the vast Indo-Gangetic basin (IGB), an important exception to the global characterization. The global debate on ‘‘water as an economic good’’ presumes that irrigation water supply is delivered, controlled, and priced by public institutions. In the developing world, the price of water is kept so low that water use cost leaves farmers no incentive to use it efficiently.

Indo-Gangetic river basins: Summary situation analysis by Challenge Program on Water and Food
The paper by the Challenge Programme on Water and Food (CPWF) - Basin Focal Project provides a brief situation analysis related to water, agriculture & poverty, water resources, water productivity, institutional aspects and opportunities & risks related to the development of the Indo-Gangetic basin (IGB). Management of IGB water resources presents some formidable challenges and, therefore, steps must be taken towards integrated management of the IGB’s water and land resources in order to ensure the future sustainability of all production and ecosystems in the basin.

Simple water use accounting of Ganges basin - A working paper by Challenge Program on Water and Food
This paper deals with basin water use accounting and is a contribution to the synthesis work of the CGIAR Challenge Program on Water and Food (CPWF) Basin Focal Projects. It applies principles of water use accounts, developed in the first of the series to the Ganges river basin in South Asia. It provides a means to assess the interactions between water, food, poverty, and the environment and helps develop sound information about water availability in a basin, where it goes and how it is used.

Emerging groundwater crisis in urban areas – A case study of Bangalore city
The paper by the Institute for Social and Economic Change documents the case of Ward No. 39 situated at the outskirts of the Bangalore city to understand the emerging groundwater crisis due to overdraft in urban areas. Bangalore has no perennial river, which resulted in the growth of many lakes, acting as a source of groundwater recharge earlier.

Increasing groundwater dependency and declining urban water quality – A comparative analysis of four South Indian cities
This paper by the Institute of Social and Economic Change (ISEC) examines the extent of groundwater dependency and quality status in four South Indian cities viz., Hubli, Dharwad, Belgaum and Kolar cities. Widespread water shortage problems have resulted in increased dependency on groundwater with tapping the resources to unsustainable levels. In Karnataka, out of 208 urban local bodies that come under Karnataka Urban Water Supply and Drainage Board, 41 depend on groundwater.

Modeling of a coastal aquifer in Goa using FEFLOW – A research report by National Institute of Hydrology
The study by National Institute of Hydrology attempts to model seawater intrusion using FEFLOW, an interactive finite element simulation system in the coastal area of Bardez taluka in North Goa and evaluate the impact of increasing groundwater development on the phenomenon. Coastal tracts of Goa are rapidly being transformed into settlement areas and the poor water supply facilities have encouraged people to develop their own sources of water by digging or boring wells.

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

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

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

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