Big-data to transform farming in poor countries

A major data-gathering project has launched to fill a yawning information gap about the activities of an estimated 500 million farmers living in poverty. The US$500-million project will gather information about seed varieties, income and farmers' technological capacities across 50 countries in Africa, Asia and Latin America. The information will help coalition members, such as the Food and Agriculture Organization of the United Nations, the Bill & Melinda Gates Foundation and national governments, to track whether their ongoing agriculture investments are making a difference. They also hope the data will enable governments to tailor their policies to help farmers.

India, United States will lose most from climate change

India, China, Saudi Arabia and the United States are the countries with the most to lose economically from climate change.
