Global climate policy impacts on livestock, land use, livelihoods, and food security.
Recent research has shed light on the cost-effective contribution that agriculture can make to global greenhouse gas abatement; however, the resulting impacts on agricultural production, producer livelihoods, and food security remain largely unexplored. This paper provides an integrated assessment of the linkages between land-based climate policies, development, and food security, with a partic...
متن کاملLivestock and global change: emerging issues for sustainable food systems.
The global food system is experiencing profound changes as a result of anthropogenic pressures. The ever-increasing human population (more than 9 billion by 2050), together with changes in consumption patterns (i.e., increasing demand for livestock products) caused by urbanization, increasing incomes, and nutritional and environmental concerns, is shaping what we eat, who eats, and how much, mo...
متن کاملThe global food supply.
There is currently a wide divergence of opinion as to whether in the year 2000 there will be sufficient food supplies to feed a prospective world population of 7 billion. The pessimists warn that even before that time there may be widespread outbreaks of famine, complete exhaustion of our natural resources, a hopelessly deteriorated physical environment, and a world ruled by virtual chaos. The ...
متن کاملMemorandum on Land Use Change and the Global Food System
The LUC (Land Use Change) term in an LCA assessment of a biofuel’s global warming effect (GW), while superposable for small excursions, is not independent of other events in the global food system. In particular, the GW effect of biofuel use resulting from remote land use change mediated by global grain markets is probably larger to the extent that food supplies are under pressure from whatever...
متن کاملLivestock , land use change , and environmental outcomes
Introduction Rapid predicted worldwide growth in demand for animal products to 2020—the so-called “next food revolution” in animal agriculture—portends complex interactions among people, biological and geophysical resources, and economic objectives. A restructuring of global food demands is expected: in contrast to current patterns, most (>60%) global production of meat and milk will be consume...
