Tompkins County food production without cheap energy: Is it possible?

As fossil fuels become less abundant and more expensive, food production systems will have to change, writes Karl North, former owner of Northland Sheep Dairy, in his recent TC Local article.

In his detailed report, North describes problem areas in our current agricultural system and how to overcome them, including issues with soil fertility, energy capture, water use, and pest control.

He also writes:
"Many uses of city land will no longer be economical in the coming years. Land will need to be converted to food production and its supporting functions, like composting and water conservation. Prime candidates for conversion are the commercial strips now inhabited by national corporate chain stores. Private and public parking lots, which energy descent writer William Kunstler sees as soon-to-be-dysfunctional “missing teeth in the urban fabric,” are another example. During Cuba’s artificially triggered encounter with “peak oil,” public interest dictated that a better use of resources was to raze ageing buildings to create urban garden space, rather than to restore them.

"In the integrated system approach described here, the functions of plants and animals will undergo marked changes. The functions of many species to facilitate tight nutrient cycling, labor, and other services that underpin the health of the whole agroecosystem, will become more important. In the case of some animals, these functions will become primary, and food production will become a secondary function, with numbers of animals on farms directed to their primary functions. The result will be a general production system model that aims for maximum sustainability, remains within the carrying capacity of the natural resource base, and within that framework, feeds the maximum number of people per acre of land used."
