Can 'nexus thinking' alleviate global water, food and energy pressures?
With demand for the world's three most precious resources only set to grow, a new approach must be put into action
Guardian Professional, Friday 25 January 2013
With the world population growing at a rate of around 80 million people a year, it is estimated that by 2030 the world will need 30% more water, 40% more energy and 50% more food. That's not just to feed, water and power the new arrivals, but also those currently living "off grid" in developing countries as they rise out of poverty.
Water, food and energy nexus debates - live broadcast
The Guardian and SABMiller bring you a day of online debates discussing how to achieve inter-connected action on water, food and energy
The Nexus of Food, Energy and Water
More than one billion people lack access to clean drinking water, sufficient food and electricity. Meanwhile, the global population is growing by some 80 million people every year.

Given the complex relationships among all three resources -- the nexus of food, energy and water -- meeting these demands will require thinking in terms of systems, not silos. It will take collaborative approaches that embrace rather than battle natural processes. And it will mean new technologies and approaches to everything from bio-fuels to desalination. This special report, produced in coordination with Wharton's Initiative for Global Environmental Leadership (IGEL), takes a close look at the key issues.
