These letters stand for the Canadian-Alberta Environmentally Sustainable Agriculture agreement. This agreement had to do with protecting Alberta's natural resources.
The Canada-Alberta Environmentally Sustainable Agricultural (CAESA) Agreement was a five-year, $34.3 million agreement between the governments of Alberta and Canada from 1992 to 1997.
The purpose of CAESA was to address issues related to the environmental impacts of farming. The main issues included soil resources, water quality, water quantity, pollution and waste management, wildlife habitat, genetic resources, air, climate and energy.
Projects were delivered through producer groups, towns and cities, native agricultural groups, applied research agencies, government agencies and universities. CAESA supported technology transfer and research on production and processing practices.
