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.

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.

The multi-location study by Carewater INREM Foundation on inland fisheries in village tanks and ponds attempts to map the changing institutional structure of the aquaculture sector in India. It looks at the socio-economic profile of fish farmers, problems faced by them, physical characteristics & economy of fishing ponds, existing property regimes, source of inputs, management of ponds and fishing as a part of village economy.

The report deals with determination of SCS runoff Curve Number and land use changes for Hamidnagar sub-basin of Punpun basin. The design of any hydraulic structure calls for the estimation of runoff. The Soil Conservation Services model, developed by USDA, computes direct runoff through an empirical equation that requires the rainfall and watershed coefficient as inputs. The watershed coefficient is called the Curve Number (CN), which represents the runoff potential of the land cover-soil complex.
