A water productivity framework for understanding and action economics of water productivity in managing water for agriculture the concept of efficiency in water resources management and policy rice production in water-scarce environments managing saline and alkali water for higher productivity opportunities for increasing water productivity of CGIAR crops through plant breeding and molecular biology world water productivity - current situation and future options improving water productivity… Expand
Opportunities to Increase Water Productivity in Agriculture with Special Reference to Africa and South Asia. Stockholm Environment Institute, Project Report - 2009
Our primary goal in this paper is to describe how improvements in water and land management can increase the productivity of water in agriculture, which, broadly defined, means getting more value orExpand
Improving agricultural water productivity: Between optimism and caution
In its broadest sense, water productivity (WP) is the net return for a unit of water used. Improvement of water productivity aims at producing more food, income, better livelihoods and ecosystemExpand
Drivers of change in agricultural water productivity and its improvement at basin scale in developing economies
We approach the issue of water productivity in agriculture by identifying five sets of drivers of change. We find that irrigation efficiencies at the field level can result in real water savingsExpand
Improving Agricultural Water Productivity: A Viable Response to Water Scarcity in the Dry Areas
Water resources in the dry areas are limited. Most of the available water is tapped, and only limited new water is expected from nonconventional sources. As more water will be needed for otherExpand
Water productivity responses and adaptation to climate change in the lower Mekong basin
A crop growth simulation model was used to study the impact of climate change for the period 2010–2050 on water productivity of rainfed rice. In general, the results suggest that water productivityExpand
Fisheries and water productivity in tropical river basins: Enhancing food security and livelihoods by managing water for fish
Faced with growing pressure upon freshwater resources, increased water productivity in agriculture is essential. Efforts to do so however need to consider the wider role of water in sustaining foodExpand
Producing more food with less water in a changing world: assessment of water productivity in 10 major river basins
This article summarizes the results of water productivity assessment in 10 river basins across Asia, Africa and South America, representing a range of agro-climatic and socio-economic conditions.Expand
More Rice, Less Water—Integrated Approaches for Increasing Water Productivity in Irrigated Rice-Based Systems in Asia
Assessment of technologies and systems for reducing water inputs and increasing water productivity at spatial scale levels from plant to field, to irrigation system, and to agro-ecological zones concluded that, while increasing the productivity of irrigated rice with transpired water may require breakthroughs in breeding, many technologies can reduce water inputs at the field level and increase field-level water productivity.

Increasing water productivity with improved N fertilizer management
There is continuing debate about the role of water productivity and the potential to increase it in response to significantly increased water demand to meet the future needs for food—estimated to beExpand
Strategies for managing saline/alkali waters for sustainable agricultural production.
Abstract Increasing the productivity of water and making safe use of poor quality waters in agriculture will play a vital role in easing competition for scarce water resources, prevention ofExpand
