Sustainable environmental stewardship:
From a planetary perspective, a food system is sustainable only when the natural inputs it uses can be environmentally regenerated, and the ecosystems and its components (water, land, air, biodiversity) are preserved and not degraded.
Sustainable environmental stewardship refers to the responsible management and care of natural resources and ecosystems in a manner that ensures their longevity and health for current and future generations, and pertaining to food systems seeks to strike a balance between providing for human needs and maintaining ecological integrity. The concept seeks to consider the long-term ecological consequences of resource exploitation, preserve biodiversity and use natural resources economically, mitigate the environmental impact of exploitive measures and recognise the interconnectedness of planetary ecosystems, calling for global coordination and action.
