This study develops a replicable framework for estimating the size and economic contribution of the bioeconomy and circular economy, using Southern Arizona as an illustrative case. It employs input–output modeling to include multiplier effects, reporting results in terms of jobs supported and value added. Because the framework relies exclusively on publicly available state- and county-level data, it can be readily applied to other U.S. regions, enabling consistent comparison across places and over time.

A survey of 1599 randomly selected Florida households was conducted in 2012 to evaluate the consumer characteristics and economic impacts of local food purchases through retail stores, restaurants, and direct-to-consumer market channels. The total annual value of local food purchases averaged $1114 per household and represented 20.1% of food purchased for at-home consumption. The total economic impacts of local food purchases in Florida were estimated at 183,625 jobs and $10.47 billion in value-added, including regional multiplier effects for agricultural production and wholesale and retail distribution. These values are significantly higher than found in previous studies in other states.
