Severe water scarcity presents the single biggest threat to future food production. Even now many freshwater sources-underground aquifers and rivers--are stressed beyond their limits. As much as 8 percent of food crops grows on farms that use groundwater faster than the aquifers are replenished, and many large rivers are so heavily diverted that they don't reach the sea for much of the year. As the number of urban dwellers climbs to five billion by 2025, farmers will have to compete even more aggressively with cities and industry for shrinking resources.

The attainment of the United Nations Millennium Development Goals would be derailed due to changes in weather patterns around the world, experts warned. Scientific research and medical journals say it will affect food production and economic growth in many countries especially developing ones.

Experts say those factors and others will make it harder to achieve the Millennium Development Goals, which seek to respond to the world’s main development challenges. The MDGs, include efforts to improve health, cut child mortality and reduce poverty and the spread of HIV/AIDS.

The 'Working 4 Ecosystems' project, which was launched by the eThekwini Municipality 18 months ago, trained residents from surrounding townships to restore green spaces in and around Giba Gorge, just 25 kilometres north of Durban, in South Africa's KwaZulu-Natal Province.

Given a poverty line, a person who is non-poor (poor) currently may not be treated as non-poor (poor) in a vulnerable situation. The poverty line is adjusted in the presence of vulnerability such that the utility of a person at the current poverty line and that at the adjusted poverty line become identical. Using an additive model of vulnerability, it is shown that if the utility function obeys constant Arrow-Pratt absolute risk aversion, then the harmonized poverty line is a simple absolute augmentation of the current poverty line.
