He explains why we need to fundamentally change the way we produce our food and how this shift can be achieved.
Simply switching from steak to salad could cut as much carbon as leaving the car at home a couple days a week. That's because beef is such an incredibly inefficient food to produce and cows release so much harmful methane into the atmosphere, said Nathan Pelletier of Dalhousie University in Canada. Pelletier is one of a growing number of scientists studying the environmental costs of food from field to plate. By looking at everything from how much grain a cow eats before it is ready for slaughter to the emissions released by manure, they are getting a clearer idea of the true costs of food. The livestock sector is estimated to account for 18 percent of global greenhouse gas emissions and beef is the biggest culprit.
Low levels of technology and the scarcity of information on climate change are some of the major obstacles for the vast majority of African farmers in adapting to global warming. Claudia Ringler, a senior research fellow at the International Food Policy Research Institute (IFPRI), says global change, including increased population, urbanization, international trade and climate change, will have significant effect on food and water security in Africa in the coming decades. Speaking at a meeting titled " How Can African Agriculture Adapt to Climate Change? Results and Conclusions for Ethiopia and Beyond" held on December 11-14, 2008 in Nazareth, Ethiopia, Ringler said rural areas in developing countries, especially Africa, will be least able to adapt to these changes, in particular climate change, as incomes and employment in rural areas are largely dependent on agriculture. "Ethiopians will find it particularly difficult to adapt because of high dependence on rainfed agriculture, very low incomes, widespread poverty and food insecurity, low levels of human and physical capital and poor infrastructure," she told IslamOnline.net (IOL).
The fall-off will strike just as 2 billion more people are added to the world's population, according to the U.N. Environment Program (UNEP), which says cereal yields have stagnated worldwide and fish catches are declining. In a new report, it said a 100-year trend of falling food costs could be at an end and that last year's sharp price rises had driven 110 million people into poverty.
In many cases, only a handful of seeds remain from rare varieties of barley, rice and wheat whose history can be traced back to the Neolithic era, said Carey Fowler of the Global Crop Diversity Trust, who is speaking on Sunday at the American Association for the Advancement of Science meeting in Chicago. "If we don't do the job right, they are gone," he said in an interview. The effort, which Fowler thinks is the biggest biological rescue effort ever undertaken, is aimed at rescuing seeds stored under less-than-optimal conditions in underfunded seed banks as well as those threatened by human and natural disasters.
In January's Restaurant Magazine, and subsequently in G2, Anthony Demetre cast the traditional caution - about the reaction of ultra-squeamish diners, presumably - to the wind, and explained how, at his Michelin-star restaurant, Arbutus, uneaten bread is used to make breadcrumbs, and wine dregs are recycled in stocks, sauces and vinegars. ... It's a matter of saving money, but also a growing sense that we are all obliged to tread as lightly as we can on this planet, and that wasting food, of all things, is morally indefensible. ... That's the rhetoric, anyway. But what of the reality? To find out how well or not I'm really doing, I spent Thursday afternoon sifting through my kitchen bin, to see what shameful waste it might reveal. |
