1 . Many cities in the United States could grow their own food locally, raising enough crops and cattle to meet the needs of all residents. This is the finding of an interesting new modeling study from Tufts University, which analyzed the potential for local food production in 378 areas across the US and expected food production.
The researchers found that cities in the Northwest in the United States had the greatest potential to raise their own food. Cities along the Eastern seaside and in the Southwest had the least potential and would not be able to meet all their own needs of diet, even if every acre of agricultural land was used for food production. This makes sense, as many of the cities are coastal and lack room for agricultural spreading.
The study revealed that the United States have a surplus (多余的) of agricultural land for feeding the domestic (国内的) population. Currently, some land is used to raise export crops, but a focus on local food production would start a conversation about how that land gets used. In the words of Peters, lead author and associate professor at the Friedman School of Nutrition Science and Policy at Tufts, “It would be important to make sure policies for supporting local or regional food production benefit conservation and create opportunities for farmers to adopt more sustainable (可持续的) practices. Policies should also recognize the ability of the natural resources in a given local or region and consider the supply chain, including ability for food processing and storage.”
Although it’s a far cry from the current reality, it is a nice thought to imagine cities surrounded by food production operations that transport freshly harvested food to nearby homes, and then make use of the leftover food to fertilize fields and generate heat for greenhouses.
