The economic value of water should be markedly higher in water-scarce regions than in water-rich regions. Similarly, then the incremental return per unit of land should be higher where land is scarcer. These hypotheses are tested by comparing the situation in western Punjab, which is land-rich and naturally water-scarce and eastern Uttar Pradesh which is land-scarce and water-rich. Our regression analysis shows that every extra unit of water diverted for agriculture generates more economic surplus in western Punjab while every extra unit of land put under cultivation generates more economic surplus in eastern Uttar Pradesh. Hence, transfer of water from a water-rich, land-scarce region to a water-scarce, land-rich region for agriculture might result in the realization of higher economic value.

Water productivity (WP) mapping is essential to evaluate the performance of current water use at the river basin scale. WP mapping is also essential to identify opportunities to improve the net gain from water by either increasing the productivity for a given consumption of water or reducing consumption without decreasing production. This requires the computation of all benefits and overall water use at a similar spatial domain. Generally the secondary data related to agricultural, livestock and poultry production are managed at administrative district level, whereas hydrological data are collected at sub-watershed scale. This scale difference, hinders estimation at hydrological scales such as sub-catchment to river basin. Due to these limitations, estimates of WP beyond field and farm scale usually do not exist, as is the case of the Karkheh River basin of Iran. To address these issues, in this paper we demonstrate an approach to estimate WP at different scales using a range of datasets. To understand the productivity gaps within and between sub-basins of the Karkheh Basin, we assessed land and water productivity for major crops using a questionnaire survey of 298 farmers. The farm-level land and water productivity in irrigated areas was considerably higher than in rainfed areas. The yield of irrigated wheat and its WP, in terms of yield per unit of gross inflow, averaged 3320±1510 kg/ha and 0.55±0.20 kg/m3, whereas the corresponding values for rainfed wheat were 1460±580 kg/ha and 0.46±0.22 kg/m.For analysis from sub-catchment to basin scale, we assessed economic WP, in terms of gross value of production per unit of actual evapotranspiration, for all agricultural enterprises including rainfed and irrigated agriculture, livestock production and overall vegetation production using remote sensing data and routine secondary data/agricultural statistics. The sub-catchment estimates show that the water productivity variability is quite high: 0.027-0.071 $/m3 and 0.120-0.524 $/m3 for rainfed and irrigated systems respectively. Inclusion of livestock changes both the magnitude and patterns of overall water productivity and in doing so highlights the importance of fully accounting for all components in agricultural production systems. The WP mapping exercise presented in this paper identified both bright- and hot-spots for helping policy makers and managers to target better resource (re)allocation and measures to enhance productivity in the Karkheh Basin. The approach is applicable to other river basins.

The overarching goal of this paper was to espouse methods and protocols for water productivity mapping (WPM) using high spatial resolution Landsat remote sensing data. In a world where land and water for agriculture are becoming increasingly scarce, growing “more crop per drop” (increasing water productivity) becomes crucial for food security of future generations. The study used time-series Landsat ETM+ data to produce WPMs of irrigated crops, with emphasis on cotton in the Galaba study area in the Syrdarya river basin of Central Asia. The WPM methods and protocols using remote sensing data consisted of: (1) crop productivity (ton/ha) maps (CPMs) involving crop type classification, crop yield and biophysical modeling, and extrapolating yield models to larger areas using remotely sensed data; (2) crop water use (m3/ha) maps (WUMs) (or actual seasonal evapotranspiration or actual ET) developed through Simplified Surface Energy Balance (SSEB) model; and (3) water productivity (kg/m3) maps (WPMs) produced by dividing raster layers of CPMs by WUMs. The SSEB model calculated WUMs (actual ET) by multiplying the ET fraction by reference ET. The ET fraction was determined using Landsat thermal imagery by selecting the “hot” pixels (zero ET) and “cold” pixels (maximum ET). The grass reference ET was calculated by FAO Penman-Monteith method using meteorological data. The WPMs for the Galaba study area demonstrated a wide variations (0-0.54 kg/m3) in water productivity of cotton fields with overwhelming proportion (87%) of the area having WP less than 0.30 kg/m3, 11% of the area having WP in range of 0.30-0.36 kg/m3, and only 2% of the area with WP greater than 0.36 kg/m3. These results clearly imply that there are opportunities for significant WP increases in overwhelming proportion of the existing croplands. The areas of low WP are spatially pin-pointed and can be used as focus for WP improvements through better land and water management practices.

This paper seeks to identify some promising policy options which could be part of a strategic and holistic effort to address India’s future water challenges. Significant increases in agricultural water productivity would be a major factor in reducing the need for developing new water sources. Crop diversification, appropriately targeted to account for the present agricultural systems and available water resources, will increase productivity. Furthermore, much more emphasis needs to be placed on effective management of the groundwater resources through renewed efforts to enhance artificial recharge and conservation. Also, efforts should be revived to improve the existing surface irrigation systems. In particular, systems could be reconfigured to provide a more reliable water supply and allow effective community level management, where appropriate. Finally, while some of the increasing demands from domestic and industrial users will be met by the development of groundwater and reallocation of water from the agricultural sector, this will not be sufficient. Given that such conditions are emerging in states with high economic growth and relatively water scarce basins, this will require the further development of water resources. In some cases, these conditions along with the demand for reliable water for high value crops, will be part of the justification for inter-basin transfers.
