report outlines a series of megatrends. Megatrend 4: Growing Food, Water, and Energy Nexus is summarized below:
"Demand for food, water, and energy will grow by approximately 35, 40, and 50 percent respectively owing to an increase in the global population and the consumption patterns of an expanding middle class. Climate change will worsen the outlook for the availability of these critical resources. Climate change analysis suggests that the severity of existing weather patterns will intensify, with wet areas getting wetter and dry and arid areas becoming more so. Much of the decline in precipitation will occur in the Middle East and northern Africa as well as western Central Asia, southern Europe, southern Africa, and the US Southwest.
We are not necessarily headed into a world of scarcities, but policymakers and their private sector partners will need to be proactive to avoid such a future. Many countries probably won’t have the wherewithal to avoid food and water shortages without massive help from outside. Tackling problems pertaining to one commodity won’t be possible without affecting supply and demand for the others. Agriculture is highly dependent on accessibility to adequate sources of water as well as on energy-rich fertilizers. Hydropower is a significant source of energy for some regions while new sources of energy—such as biofuels—threaten to exacerbate the potential for food shortages. There is as much scope for negative tradeoffs as there is the potential for positive synergies. Agricultural productivity in Africa, particularly, will require a sea change to avoid shortages. Unlike Asia and South America, which have achieved significant improvements in agricultural production per capita, Africa has only recently returned to 1970s’ levels."
