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. Keywords: Water, Power, Energy, Agriculture, Dams, Climate change, Run-of-River Plants

Over the next few years, Tunisia will face a growing scarcity of water. The concept of a food consumption water footprint has been recently applied to expand knowledge about water management and to respond to problems of food insecurity. In this study, following the Water Footprint Network (WFN) method, we assessed and analysed the food consumption water footprint of Tunisian households by geographical location and by group of food products. We used results from national food surveys to collect the quantities of food consumed and the WFN database containing water footprints of food products specific to Tunisia. We found that the average water footprint for the main consumed food groups has increased by 31% during recent decades, from 1208 m³/capita/year in 1985 to 1586 m³/capita/year in 2010. Despite the decline in cereal consumption in Tunisia, the food water footprint has continued to rise as a result of increased consumption of animal source products. This increase is associated with regional variations in food choices that imply large differences in water footprints. Urban diets present higher water footprints than rural diets proportionally to higher standards of living. This study provides a new perspective on the water footprint of food consumption in Tunisia by using dietary data at the household level and demonstrated significant variability in water footprints due to different food consumption modes, and socio-economic and geographic characteristics. Future food consumption trends will likely create more pressure on water resources, especially in Tunis city and coastal areas of Tunisia. Special measures related to price policies, sensitization of consumers, and changes in production systems may have to be taken by policy makers to reduce the water footprint in order to improve food security strategies and water management in Tunisia.

This article investigates the relationship between the water-energy-food (WEF) nexus in Brazil in an exploratory and statistical study over the period from 2000 to 2013. For that purpose, the explanatory variables considered were the following: Access to improved water; Access to electricity and Average protein supply. Furthermore, some brief facts about WEF nexus security in Brazil was introduced. With such explanatory variables, descriptive statistics was performed, ensuring the assumption of data normality approach, and consequently calculating the descriptive statistics and correlation. The results of correlation showed that the quantitative relation between the three factors was extremely strong. These data allowed to understand the relation between these indicators and its status as a nexus in Brazil. Therefore, it is concluded that pursuing an active policy to manage demand in WEF nexus could lead sustainability processes.
