Food systems include all the processes and infrastructure involved in feeding a population from growing, harvesting, processing, packaging, and transportation to marketing, consumption, and disposal of food and food-related items. These systems are influenced by culture, economics, politics, and the environment. ASU researchers are studying the sensitivity of food systems to global change.

EASM-3: Collaborative Research: Physics-based Predictive Modeling for Integrated Agricultural and Urban Applications

A collaborative and interdisciplinary team from Arizona State University and the National Center for Atmospheric Research jointly develops integrated agricultural and urban models necessary to examine hydroclimatic impacts and economic and social benefits/tradeoffs associated with agricultural and urban land use/cover changes accompanying localization of food production within cities.

Testing Macronutrient Imbalance as a Key Factor Limiting Range Expansion in Herbivores

This research project is taking advantage of an ongoing outbreak of the South American locust (Schistocerca cancellata) to test the hypothesis that the ability for S. cancellata to attain a balance of nutrients optimal for growth limits their capacity to maintain persistent high populations over broad regions of South America. Locusts are a major challenge for food security globally, with outbreaks causing 80-100% crop losses. In the future, working collaboratively with government plant protection agencies, this research can be directly applied to strategies to improve livelihoods, human and environmental health, and global food security. Moreover, this award will support postdoctoral and student training, and cross-cultural exchange.
