A few years ago, Sir John Beddington, the UK government’s chief scientific advisor stated that with the world’s population growing, food supplies diminishing, and water supplies becoming more scarce, all of these factors would combine to form a ‘perfect storm’ in 2030 resulting in food shortages and rioting. However, the New England Complex Systems Institute believes he is way too optimistic with his timing. In fact, the complexity theorists think that if we don’t reverse the current trend in food prices, we’ve got until August 2013 before social unrest sweeps the planet.

With more than half the world now living in urban centres, city residents’ quality of life, vulnerability to natural hazards and diets are matters of growing importance, drawing significant attention at the World Urban Forum in Naples, Italy, this week.

Two major studies launched to coincide with the Forum explore these issues. Both focus on the role of local governments and community initiatives in shaping sustainable policies for poor urban dwellers: Growing Greener Cities in Africa, a report from the UN Food and Agriculture Organisation (FAO); and the Making Cities Resilient Report 2012, produced by the London-based International Institute for Environment and Development (IIED) for the UN Office for Disaster Reduction (UNISDR).

Earth’s growing human population needs fresh water for drinking and food production. Fresh water, however, is also needed for the growth of biomass, which acts as a sink of carbon dioxide and thus could help mitigate climate change. Does the Earth have enough freshwater resources to meet these competing demands?

An American Geophysical Union release reports that J. Rockström and colleagues, in their recent study, estimate the order of magnitude of freshwater consumption needed to feed a population of nine billion people by 2050 and the amount of water needed to realize the planet’s full biomass carbon sequestration potential.
