Deutsch's research examines the couplings between the ecological effects of globalization of food production systems and national policy and economic accounts. She particularly focuses on the ways in which global trade can change the mix of inputs to food and feed by estimating the ecosystem subsidies needed to support intensive livestock and aquaculture production systems. She also enjoys tracing and mapping food flows to cities to explore how cities feed themselves.
Her work contributes to the development of a set of complementary tools that can be used in economic accounting at national and international scales that address ecosystem support and performance.
Deutsch was an Adjunct Fellow of the Australian National University within the Fenner School of Environment & Society 2008–2011. She continues her work in the UN-sponsored LEAD-SCOPE project 'Livestock in a Changing Landscape' as an expert advisor.

Global seafood trade leave consumers unaware of over-exploited marine ecosystems

Climate change, financial shocks, and fluctuations in international trade are some of the reasons why resilience is increasingly invoked in discussions about land-use policy. However, resilience assessments come with the challenge of operationalization, upscaling their conclusions while considering the context-specific nature of land-use dynamics and the common lack of long-term data. We revisit the approach of system archetyp...

Food lies at the heart of both health and sustainability challenges. We use a social-ecological framework to illustrate how major changes to the volume, nutrition and safety of food systems between 1961 and today impact health and sustainability. These changes have almost halved undernutrition while doubling the proportion who are overweight. They have also resulted in reduced resilience of the biosphere, pushing four out of s...

Freshwater use for food production is projected to increase substantially in the coming decades with population growth, changing demographics, and shifting diets. Ensuring joint food-water security has prompted efforts to quantify freshwater use for different food products and production methods. However, few analyses quantify freshwater use for seafood production, and those that do use inconsistent water accounting. This inh...

Nearly 40% of seafood is traded internationally and an even bigger proportion is affected by international trade, yet scholarship on marine fisheries has focused on global trends in stocks and catches, or on dynamics of individual fisheries, with limited attention to the link between individual fisheries, global trade and distant consumers. This paper examines the usefulness of fish price as a feedback signal to consumers a...
