The Water Accounting Plus (WA+) framework uses open access remote sensing and GIS data and hydrological model output. This framework uses Budyko hypothesis and thus makes use of ‘green’ water and ‘blue’ water accounting. We applied the WA+ framework to the Subarnarekha basin, India, to assess the total water consumptions and land productivity (LP) and water productivity (WP) for a period of 12 years from 2003 to 2014 by using satellite and open data sources. The total water consumptions in the basin for 2013–14 (wet year) and 2010–11 (dry year) are 27.1 BCM/year and 23.1 BCM/year, respectively. The LP in the basin is found to vary from 1575 to 2141 kg/ha/year (with an average of 1921 kg/ha/year) and 1315–2325 kg/ha/year (with an average of 1948 kg/ha/year) during the period of 2003-04 to 2013–14, respectively for rainfed and irrigated cereals. Similarly, the WP is found to vary from 0.34 to 0.49 kg/m³ (with an average of 0.42 kg/m³) and 0.38–0.69 kg/m³ (with an average of 0.59 kg/m³) during the period of 2003-04 to 2013–14, respectively for rainfed and irrigated cereals. This study shows that the WA+ framework can be successfully applied for analyzing water consumption patterns, land productivity and WP of irrigated and rainfed crops individually. The results are available in map form, it is easy to identify the places/farmers with low LP and WP and work with them to improves these. Such efforts will ultimately lead to efficient management of water resources in the basin and poverty alleviation.

Water Accounting Plus (WA+) 框架使用开放访问遥感和 GIS 数据以及水文模型输出。该框架使用 Budyko 假设，因此使用“绿色”水和“蓝色”水核算。我们将 WA+ 框架应用于印度 Subarnarekha 盆地，通过使用卫星和开放数据源评估 2003 年至 2014 年 12 年期间的总耗水量、土地生产力（LP）和水生产力（WP）。2013-14（雨年）和2010-11（旱年）流域总耗水量分别为27.1 BCM/年和23.1 BCM/年。流域中的 LP 变化范围为 1575 至 2141 公斤/公顷/年（平均 1921 公斤/公顷/年）和 1315-2325 公斤/公顷/年（平均 1948 公斤/公顷/年） ) 2003-04 至 2013-14 年期间，分别用于雨养和灌溉谷物。2003-04 年至 2013-14 年期间，雨育和灌溉谷物分别为³（平均 0.42 kg/m ³）和 0.38-0.69 kg/m ³（平均 0.59 kg/m ³）。本研究表明，WA+ 框架可成功应用于单独分析灌溉和雨育作物的耗水模式、土地生产力和 WP。结果以地图形式提供，很容易识别低 LP 和 WP 的地方/农民，并与他们一起改进这些。这些努力最终将导致流域水资源的有效管理和扶贫。
