Solar-powered drip irrigation enhances food security in the Sudano–Sahel documents a field research project which found that: "solar-powered drip irrigation significantly augments both household income and nutritional intake, particularly during the dry season, and is cost effective compared to alternative technologies" Over the decades, irrigation has been shown to greatly increase agricultural productivity. Drip irrigation is spreading rapidly in Africa, with significant benefits. "Drip irrigation delivers water (and fertilizer) directly to the roots of plants, thereby improving soil moisture conditions; in some studies, this has resulted in yield gains of up to 100%, water savings of up to 40–80%, and associated fertilizer, pesticide, and labor savings over conventional irrigation systems" The solar-powered systems, however, look to offer the potential for even better results. From the study on impacts of PVDI systems it was reported: "The women’s agricultural group members utilizing the PVDI systems became strong net producers in vegetables with extra income earned from sales, significantly increasing their purchases of staples, pulses, and protein during the dry season, and oil during the rainy season. Finally, survey respondents were asked how frequently they were unable to meet their household food needs. Based on the frequency and most recent incident, households were assigned a food insecurity score ranging from zero (no problems during the previous year) to one (perpetually unable to meet food needs). This score changed significantly for project beneficiaries, as they were 17% less likely to feel chronically food-insecure. In short, the PVDI systems had a remarkable effect on both year-round and seasonal food access."

Bloomberg.com has reported that the Obama administration is planning to launch an official complaint against China with the World Trade Organisation (WTO) pertaining to the country's stringent web censorship policies. Illinois Senator Richard Durbin has announced that he plans to pass a legislation that will allow the government to prosecute US internet companies if they violate the human rights of their customers when a foreign government asks them to do so. 

Today, he is emerging as one of the nation’s archreformers, pushing to impose some of the most stringent new financial regulations in history. And as the head of the Commodity Futures Trading Commission, the leading contender to oversee the complex derivatives contracts that played a central role in the financial crisis and, in turn, the Great Recession, he is in a position to influence the outcome. It may seem an unlikely conversion, but it is one that has won the approval of Brooksley E. Born, of all people, a former outspoken head of the commission. She sounded alarms more than a decade ago about the dangers hiding in the poorly understood derivatives market and was silenced by the same Washington power brokers that counted Mr. Gensler as a member. Mr. Gensler opposed Ms. Born, according to people who worked at the commission in the 1990s, and in 2000 played a significant role in shepherding through Congress deregulation measures that led to explosive growth of the over-the-counter derivatives market. That was then. These days, Ms. Born is convinced of Mr. Gensler’s reformist zeal, as he takes on Wall Street in what is becoming one of the fiercest battles over regulation in the postcrisis era. “I think he is doing very well,” she said in an interview. “He certainly seems to be committed to robust oversight of derivatives and limiting excessive speculation and leverage.” The proposals championed by Mr. Gensler, if adopted by Congress, would substantially alter what is now a largely unregulated market in over-the-counter derivatives, financial instruments used by companies and investors to protect themselves and bet on moves in variables, like interest rates or currencies, and to speculate. The proposals include forcing the big banks that sell derivatives to conduct their trades in the open on public exchanges and clear them through central clearinghouses, so that any investor can see the prices that dealers charge their customers. Today, those transactions are bilateral and private.
