Concept
Sustainable food system
Summary
A sustainable food system is a type of food system that provides healthy food to people and creates sustainable environmental, economic, and social systems that surround food. Sustainable food systems start with the development of sustainable agricultural practices, development of more sustainable food distribution systems, creation of sustainable diets, and reduction of food waste throughout the system. Sustainable food systems have been argued to be central to many or all 17 Sustainable Development Goals.
Moving to sustainable food systems, including via shifting consumption to sustainable diets, is an important component of addressing the causes of climate change and adapting to it. A 2020 review conducted for the European Union found that up to 37% of global greenhouse gas emissions could be attributed to the food system, including crop and livestock production, transportation, changing land use (including deforestation), and food loss and waste. Reduction of meat production, which accounts for ~60% of greenhouse gas emissions and ~75% of agriculturally used land, is one major component of this change.
The global food system is facing major interconnected challenges, including mitigating food insecurity, effects from climate change, biodiversity loss, malnutrition, inequity, soil degradation, pest outbreaks, water and energy scarcity, economic and political crises, natural resource depletion, and preventable ill-health.
The concept of sustainable food systems is frequently at the center of sustainability-focused policy programs, such as proposed Green New Deal programs.
There are many different definitions of a sustainable food system.
From a global perspective, the Food and Agriculture Organization of the United Nations describes a sustainable food system as follows:
A sustainable food system (SFS) is a food system that delivers food security and nutrition for all in such a way that the economic, social and environmental bases to generate food security and nutrition for future generations are not compromised.
