To grasp water scarcity, researchers probe links between human and natural systems

  Understanding the fine-level interactions between nature and people is essential in determining whether a region will suffer water scarcity in the future. That's a key finding of a study titled "Finding Water Scarcity Amid Abundance Using Human-Natural System Models," to be published next week in Proceedings of the National Academy of Sciences.

  Up to 2 billion people around the world face water shortages now and in the future, said the study's lead author, William Jaeger, an economist in Oregon State University's College of Agricultural Sciences. Emerging scarcities are tied to factors such as growing populations, rising standards of living and climate change.

  "Recent droughts across the West have underscored the vulnerability of even highly developed economies to water scarcity," Jaeger said. "And climate change will only heighten the need to anticipate water shortages worldwide." It's a daunting task, he said, because the interactions between natural water supply and human water demands are complex, and involve "linkages and feedbacks" that are difficult to anticipate.

Want to save the world from hunger? Start by not wasting food

Consumers are being urged to use their imagination and create recipes from food that would otherwise go to waste, as part of a campaign to raise money to tackle global hunger.

The World Food Programme has launched a social media movement, #RecipeforDisaster, with the aim of making the public more conscious of the food waste they generate.

Although there is enough food in the world to go around, one-third of the 4bn tonnes produced each year is wasted, costing the global economy nearly $750bn (£530bn) annually.

“In developing countries the majority of food is wasted in storage and production, which WFP is helping to address with new technologies and community education. However, in the developed world most food is lost on the plate. Recipe for Disaster aims to confront this issue and get people to take action by creating a meal and making a donation.”
