The future of food: how sustainable food production is revolutionizing agriculture

In definition 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.

In order to be sustainable, the development of the food system needs to generate positive value along three dimensions simultaneously to assure sustainable food production: economic, social and environmental.

• Economic dimension, a food system is considered sustainable if the activities conducted by each food system actor or support service provider are commercially or fiscally viable. The activities should generate benefits, or economic value-added, for all categories of stakeholders: wages for workers, taxes for governments, profits for enterprises, and food supply improvements for consumers.
• Social dimension, a food system is considered sustainable when there is equity in the distribution of the economic value, taking into account vulnerable groups categorized by gender, age and race. Most importantly, food system activities need to contribute to the advancement of important socio-cultural outcomes, such as nutrition and health, traditions, labor conditions, and animal welfare.
• Environmental dimension, sustainability is determined by ensuring that the impacts of food system activities on the surrounding natural environment are neutral or positive, taking into consideration biodiversity, water, soil, animal and plant health, the carbon footprint, the water footprint, food loss and waste, and toxicity
