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. By 2030, the nine billion people living on earth will need 30% more water, 40% more energy and 50% more food to survive.
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.
