Example text

LOSS OF LOCAL CONTROL OVER AGRICULTURAL PRODUCTION Millions Accompanying the concentration of agriculture into large-scale monocultural systems and factory farms has been a dramatic decline in the number of farms and farmers, especially in developed countries where mechanization and high levels of external inputs are the norm. S. 5 million to just over 2 million, and the percentage of the population that lives and works on farms has dropped below 2%. S. S. S. Census Bureau, 2005). In developing countries as well, rural people who work primarily in agriculture continue to abandon the land to move to urban and industrial areas, which will hold an estimated 60% of the world’s population by 2030.

Faced with such economic uncertainty, there is less incentive for farmers to stay on the land. One trend is for larger farmers to buy out their smaller neighbors. But when agricultural land is adjacent to rapidly expanding urban centers, such as in California, the incentive instead is to sell farmland at the inflated value it has as urban land. , 2001). In less developed countries, the growth of large-scale export agriculture has an even more ominous effect. As rural people — who were once able to feed themselves adequately and sell surplus food to city-dwellers — are pushed off the land, they migrate to cities, where they become dependent on others for their food.

The diagram could be extended in the upward direction to include regional, national, and global levels of organization, which would involve such things as markets, farm policy, even global climate change. In the downward direction, the diagram could include the cellular, chemical, and atomic levels of organization. understood in terms of individual organisms alone. In an agroecosystem context, this principle means in essence that the farm is greater than the sum of its individual crop plants. Sustainability can be considered the ultimate emergent quality of an ecosystem approach to agriculture.
