European renewable energy targets are driving widespread conversion of African lands for agrofuels, threatening to exacerbate hunger in poor regions and increase carbon emissions across the continent, according to a new report. National governments and private companies are increasingly acquiring agricultural land in Africa to grow crops to (more…)

Ten countries worldwide, including five African nations, are at “extreme risk” because of limited access to clean, fresh water, according to a new global water security index. And the effects of climate change and population growth will exacerbate the stress on these water supplies, potentially threatening stability in many regions, according to the analysis by Maplecroft , a UK-based consulting group. Among the nations most at risk are Somalia, Mauritania, Sudan, Niger, and Iraq. Other nations at extreme risk — including Pakistan, Egypt, and (more…)

Solar-powered drip irrigation systems significantly increased vegetable production in villages in the western African nation of Benin, improving nutrition and boosting household incomes, according to a new study. The study, led by a researcher at Stanford University’s Program on Food Security and the Environment, installed solar-powered drip irrigation systems in two villages in Benin and compared the impact with two nearby villages that did not have drip irrigation systems.

The study found that, after a year, farmers with the solar irrigation systems saw vegetable production increase by 500 to 750 grams per person per day — three to five times greater than the villages that did not have irrigation systems.

The significantly increased yield meant that farmers could feed their families and sell up to 80 percent of their harvest at local markets, sharply increasing household income, according to the study, published in the Proceedings of the National Academy of Sciences. (more…)
