Livestock and the environment Finding a balance
1995Also available in:
No results found.The degree of potential environmental impacts of the different livestock production systems are illustrated crudely by their relative consumption of feeds. The types of environmental impacts likely to derive from the production, transport and processing of feeds are outlined in Chapter 4, being mainly due to land-use and cropping for commodity production. Possible direct and indirect indicators of these impacts are identified in Chapter 5, though these remain to be tested in particular applicati ons. -
Book (stand-alone)Pollution from industrialized livestock production 2007In recent decades, livestock production has increased rapidly, particularly in the developing world. Most of the increased production comes from industrial farms clustered around major urban centres. Such large concentrations of animals and animal wastes close to dense human population often cause considerable pollution problems. The rapid growth of livestock production highlights the urgent need for effective policies to regulate intensive livestock operations and su pport environmentally and economically sustainable approaches to handling waste.

No results found.Industrial production of pork, poultry and (feedlot) beef and mutton is the fastest growing form of animal production. In 1996, it provided more than half the global pork and poultry (broiler) production and 10 percent of the beef and mutton production. This represented 43 percent of the total global meat production, up from 37 percent in 1991-93. Moreover, it provided more than two-thirds of the global egg supply. Geographically, the industrialized countries dominate industrial pig and poultry production accounting for 52 percent of the global industrial pork production and 58 percent of the poultry production. Asia contributes 31 percent of the world's pork production (Sere and Steinfeld, 1996). Industrial ruminant production is concentrated in Eastern Europe, the ex-Soviet Union and in the OECD countries. Typical examples are large-scale feedlots in the USA and in the formally centrally planned economies. Industrial sheep feedlots are found in the Near East, North Africa and th e USA. The industrial production system is open both in physical and economic terms. It depends on outside supply of feed, energy and other inputs. Technology, capital and infrastructure requirements are based on large economies of scale and, because of this, production efficiency is high in terms of output per unit of feed or per man-hour, less so when measured in terms of energy units. Yet as the world's main provider of eggs, poultry meat and pork at competitive prices, it meets most of the escalating demands for low cost animal products in rapidly growing urban centres of the developing world.
