Dairy-Feed-Water Nexus: Arizona’s Dairy Industry and Feed Supply Chain
Paper Presentation in a Themed Session Ashley Kerna Bickel, Dari Duval, George Frisvold
Amidst growing interest in and demand for local foods, dairy is a major driver of production for local consumption in Arizona. That said, in-state sourcing of feed crops by the dairy industry is often overlooked as a step along the local foods value chain. Furthermore, increasing emphasis on the sustainability of food production, particularly in arid climates facing the prospect of shortages in agricultural irrigation water supplies, warrants the examination of feed crop production in relation to use by Arizona dairy producers. This analysis will use secondary data on dairy industry and crop production, secondary data on agricultural water use and crop production practices, and primary data from Arizona dairy producers. Additionally, it will utilize the IMPLAN input-output model to estimate multiplier effects attributable to the dairy industry value chain. Results will provide an estimate of the contribution of the dairy industry value chain to the state economy and provide context from the food systems perspective on the trade-offs surrounding production and sustainability.
Tracing a Tropical Mangrove Food System in Times of Globalised Change
Paper Presentation in a Themed Session C. Julián Idrobo, Katherine L. Turner
Tropical mangrove ecosystems provide key benefits and resources, such as carbon sequestration, biodiversity conservation, erosion buffering for coastal zones and food and fuel production. In spite of these contributions, the local populations that inhabit this ecosystem are rarely the direct recipients of such benefits and resources. Increasingly these dynamics are extending into the local food system as well. Most of the foodstuffs produced in mangroves are consumed elsewhere and a considerable proportion of what is consumed locally is imported from far away. Based on a case study conducted in the mangrove community of Sivirú on the northern coast of the Colombian Pacific, we examine the local food system by tracing the inward and outward flows of foodstuffs. We find that food production occurs in three main subsystems that in turn are linked to specific distribution routes and markets. Cockles, fish, and coconut are key foodstuffs that are traded in extra-local markets. Rice, which is a local staple and primarily used for internal consumption, now depends on certified seeds that are imported into the community. Other foodstuffs, such as plantain, forest fruits and herbs are only consumed internally and remain to a great extent independent. In spite of the productivity and diversity of the local ecosystem, recent decades have seen growing dependence on imported foods for local consumption. These deep connections with regional and international markets are examples of how globalisation has blurred the lines between the local and global even in a community as geographically isolated as Sivirú.
