Food security in a transforming system of global environmental change (GEC)

FAC Policy Brief 54
by Laura Pereira

The world’s food system is undergoing an unprecedented transformation: not just from the significant impacts of global environmental change (GEC), but also from the rapid expansion of transnational agribusiness. The food system is now a globalised, interconnected socioecological system and the global South is increasingly being integrated into this new, interconnected, efficiency-driven model.

There are three key outcomes of a wellfunctioning food system: food security, social welfare and environmental welfare (see Figure 1) yet, our current system has so far failed to provide these for the planet’s poor. How, then, will the future food system respond to the challenge of providing food security whilst also adapting to issues of rapid environmental and sustainability issues – most notably climate change? Developing a system of adaptive governance to meet these challenges is clearly an important area for research, but it requires an understanding of the complexity and uncertainty inherent in such measures.
