Eco-farming can double food output in developing world

Many farmers in developing nations can double food production within a decade by shifting to ecological agriculture from use of chemical fertilizers and pesticides, a U.N. report showed on Tuesday. Insect-trapping plants in Kenya and Bangladesh's use of ducks to eat weeds in rice paddies are among examples of steps taken to increase food for a world population that the United Nations says will be 7 billion this year and 9 billion by 2050. "Agriculture is at a crossroads," according to the study by Olivier de Schutter, the U.N. Special Rapporteur on the right to food, in a drive to depress record food prices and avoid the costly oil-dependent model of industrial farming. "Agroecology" could also make farms more resilient to the projected impact of climate change including floods, droughts and a rise in sea levels that the report said was already making fresh water near some coasts too salty for use in irrigation.

Canada: Lead and asbestos in homes need tighter control

The health risks from toxins such as lead in old paint or asbestos in walls are too often overlooked when homes are upgraded, according to a study on Sunday calling on governments to set tougher pollution rules. The report, by Canadian experts, said that retrofits of old buildings, such as insulation meant to save energy and limit greenhouse gas emissions, often released poisons that can be especially damaging to children. "Without sufficient care, retrofits...can increase the health risks," Theresa McClenaghan, executive director of the Canadian Environmental Law Association (CELA), told Reuters as she outlined a CELA project to limit health risks.
