Water, energy and food nexus of Indus Water Treaty (IWT) is presented in the light of water governance. The water governance doctrine refers to social, economic, administrative and political systems influencing the transboundary water use and management. Water governance means who gets what water, when and how much, and who has the right to water related benefits. Indus Water Treaty is cited to be one of the few successful settlements of boundary water basin conflicts that has stood the test of times since last six decades. Riparian states have opportunities of harvesting water, power and agriculture by compliance to accords in letter and spirit. IWT restrains both (India) and lower (Pakistan) riparian from pulling out of accord from fear of deadly consequences. IWT is founded on World Bank’s professionally prepared comprehensive terms and conditions keeping in mind future regional developments. This treaty has given control of three eastern rivers (Ravi, Beas and Sutlej) to India and three western rivers (Indus, Jhelum and Chenab) to Pakistan. IWT gives both countries genuine share of eastern/western waters for domestic use, agriculture and electricity generation using Run-of-River Plants, subject to observing minimum level of water flow into lower riparian at Head Marala Barrage. Water, energy and food nexus of this treaty bonds upper and lower riparian to comply with water governance principles. Upper riparian diverted 34 million acre feet (MAF) water out of eastern rivers before entering into Pakistan and launched run-of-river power plants spree on western rivers in last two decades. Restricting water flow to lower riparian in the name of pond filling needs attention. Unrestricted use of water in run-of-river power plants is pointed out to be a limiting factor in Indus Water Treaty. Continuum of cooperation has room for collaboration under Indus Water Treaty. India and Pakistan can sort out disputes by dialogue, in light of rights and needs, rather Harmon Doctrine.

Access to sufficient and clean freshwater is essential for all life. Water is also essential for the functioning of food systems: as a key input into food production, but also in processing and preparation, and as a food itself. Water scarcity and pollution are growing, affecting poorer populations most, and particularly food producers. Malnutrition levels are also on the rise, and this is closely linked to water scarcity. The achievement of Sustainable Development Goals (SDG) 2 and 6 are co-dependent. Solutions for jointly improving food systems and water security outcomes include: (1) strengthening efforts to retain water-based ecosystems and their functions; (2) improving agricultural water management for better diets for all; (3) reducing water and food losses beyond the farmgate; (4) coordinating water with nutrition and health interventions; (5) increasing the environmental sustainability of food systems; (6) explicitly addressing social inequities in water-nutrition linkages; and (7) improving data quality and monitoring for water-food system linkages, drawing on innovations in information and communications technology (ICT). Climate change and other environmental and societal changes make the implementation and scaling of solutions more urgent than ever.

Water scarcity is already a reality. More food will be required for a growing and wealthier and urbanized population that will put more pressure on water resources. With several water-related limits reached or breached - groundwater decline, shrinking rivers and threatened fisheries - we must ask, Will there be enough water to grow enough food? It is possible to produce the food needed, but if present practices continue it is not probable that we will solve the many poverty and environmental challenges confronting us. To share a scarce resource and to limit environmental damage in the face of climate change, it is imperative to limit future water use. Important pathways to growing enough food with limited water are to increase productivity of water in irrigated and rainfed areas, improve water management in low-yielding rainfed areas, and to consider our own food consumption patterns. In pockets of poverty in sub-Saharan Africa and Asia, expanding access to water through a range of water management solutions holds the key to food security and poverty reduction. For sustainable water use, water managers must consider agriculture as an ecosystem and how other ecosystem services are impacted through water. These actions will require serious changes in how we think about water and food, and how we govern water and land resources.

This database provides information about the amount of water use in agriculture food systems covering all sectors from farming to food processing industries. The data are presented at the country level with sectoral disaggregation following the Nexus Social Accounting Matrix (SAM) sectoral specifications. The database also differentiates the type of water in each sector based on water sources. The green water refers to type of water originated from precipitation or rain, while the blue water refers to all water that comes from irrigation covering both surface and groundwater. Both types of water are consumed by plants or animals during the production process. The grey water on the other hand is the amount of water generated as an implication from production activities that cause the water polluted. Since it has loads of pollutants created from production activities, this type of water can be seen as a waste in the whole production system.
