The Water, Energy and Food Security Nexus 

Nexus approach can enhance water, energy and food security by increasing efficiency, reducing trade-offs, building synergies and improving governance across sectors.    http://www.youtube.com/watch?v=CKW_ux2Xo_w

The Water, Energy and Food Security Nexus

Productivity and the availability of water, energy and land vary enormously between regions and production systems. There is a large potential to increase overall resource use efficiency and benefits in production and consumption, e.g. by addressing intensive agriculture (which often has higher water productivity but lower energy productivity than other forms of agriculture) or water- and energy-intensive meat products. The nexus approach can boost this potential by addressing externalities across sectors. For example, nexus thinking would address the energy intensity of desalination (also termed ‘bottled electricity’), or water demands in renewable energy production (e.g. biofuels and some hydropower schemes) or water demands of afforestation for carbon storage. Also, action to avoid or land degradation saves water and energy, for example by increasing soil water storage and groundwater recharge, as well as reducing the use of energyintensive fertiliser.
