Investing in ecosystem services can boost food security: UN

Investing in ecosystem services can boost food security: UN  This new UNEP report launched during World Water Week in Stockholm, focuses on the links between ecosystems, water and food, and illustrates how resilient ecosystems can support and increase food security. Against the current challenges to enhance food security worldwide, the publication aims at illustrating the importance of healthy ecosystems for the provisioning of key services that contribute to food security. Such ecosystem services are water provisioning and food production. In this regard the publication will provide an overview of the linkages between ecosystems, water, and food security. The publication further will explore how to manage ecosystems for a variety of […]

Root of the Problem

We’ve plowed and seeded more than 40 percent of the Earth’s land surfaces, introduced alien species into new territories, poured carbon dioxide into the atmosphere, disrupted natural climate cycles, and polluted aquatic ecosystems with excessive nitrogen and other contaminants. These far-reaching changes have spurred scores of researchers to examine the impacts of human activities on biodiversity […]

Crops with deeper roots capture more carbon, fight drought: study

By David Fogarty, Singapore, Reuters, US, August 5, 2011 http://www.reuters.com/article/2011/08/05/us-crops-carbon-idUSTRE77412Q20110805 (Reuters) – Creating crops with deeper roots could soak up much more carbon dioxide from the air, help mankind fight global warming and lead to more drought-tolerant varieties, a British scientist says in a study. Douglas Kell of the University of Manchester says crops can play a crucial role in tackling climate change by absorbing more of mankind’s rising greenhouse gas emissions from burning fossil fuels. Doubling root depth to two meters would also make crops more drought resistant, improve soil structure and moisture, store more nutrients and reduce erosion, Kell says in the study published online in the Annals of […]

ASSURING FOOD SECURITY IN DEVELOPING COUNTRIES: CONTINUING WITH BUSINESS AS USUAL APPROACHES IS NOT AN OPTION

Small integrated farms with off-grid renewable energy may be the perfect solution to the food and financial crisis while mitigating and adapting to climate change sustainable energy Dr. Mae-Wan Ho An emerging scientific consensus that a shift to small scale sustainable agriculture and localized food systems will address most, if not all the underlying causes of deteriorating agricultural productivity as well as the conservation of natural soil and water resources while saving the climate To substantially improve living standards, access to modern energy is also crucial. Small agro-ecological farms are known to be highly productive, and are ideally served by new renewable energies that can be generated and used on […]

Climate change to reduce water availability, FAO warns

XINHUA APA woman piles up wheat after harvesting at a farm in village Majra Khurd of Haryana. File photo Climate change will make water less available to produce food crops in years to come, the United Nations Food and Agriculture Organization (FAO) said in a report issued Thursday. River runoff and aquifer recharges will decrease in the Mediterranean, the Americas, Australia and southern Africa, it said. Areas in Asia which depend on the melting of ice and mountain glaciers will also be affected, while areas with a lot of fluvial deltas are threatened by reduced water flow, increased salinity and rising sea levels, said the report entitled “Climate Change, Water […]

Mapping hotspots of climate change and food insecurity in the global tropics

Polly Ericksen, Philip Thornton, An Notenbaert, Laura Cramer, Peter Jones, Mario Herrero. Executive Summery This study was coordinated by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) to identify areas that are food insecureand vulnerable to the impacts of future climate change, across the priority regions for the CGIAR centres. The research was undertaken by a team of scientistsfrom the International Livestock Research Institute (ILRI). The study relied on maps: first, of variables that indicate the different aspects of food security(availability, access and utilization), and second, of thresholds of climate change exposure important for agricultural systems. Vulnerability was assessed usinga domain approach based upon the Intergovernmental […]

A warming planet struggles to feed itself

Justin Gillis http://www.hindu.com/2011/06/06/stories/2011060662511300.htm The dun wheat field spreading out at Ravi P. Singh’s feet offered a possible clue to human destiny. Baked by a desert sun and deliberately starved of water, the plants were parched and nearly dead. Dr. Singh, a wheat breeder, grabbed seed heads that should have been plump with the staff of life. His practiced fingers found empty husks. “You’re not going to feed the people with that,” he said. But then, over in Plot 88, his eyes settled on a healthier plant, one that had managed to thrive in spite of the drought, producing plump kernels of wheat. “This is beautiful!” he shouted as wheat beards […]
