Resumen
Descripción
Sustainable agriculture is garnering renewed interest as more customers and retailers from both the U.S. and the world markets demand more sustainably sourced products and ingredients. Processed vegetables (canned and frozen) such as sweet corn and green beans face this same growing demand. To respond to this growing demand for sustainability data and programs, the Midwest Food Processors Association and the Wisconsin Potato and Vegetable Growers Association chose the National Initiative for Sustainable Agriculture (http://wisa.
cals.wisc.edu/nisa) approach. This approach develops a farmer self-assessment survey that documents grower adoption of multiple sustainable practices, and then analyzes the data using data envelope analysis with principal components to develop a “sustainability score” for both individual growers and the industry as a whole.
