The concept of planetary boundaries addresses the resource limits of the planet.
In particular, limited freshwater and nutrients for agriculture are a concern, especially as demand increases due to expectations for common standards of living, as well as a growing human population. Climate change is making crop yields less predictable.  At the same time, conventional agriculture is wasteful of these resources and puts more pressure on limited freshwater resources. Aquaponics is being considered as an approach to food security that may provide resilience in the face of these potential encroachments on planetary boundaries. These systems can be placed locally to reduce the need for transportation of food; they conserve water and nutrients and so may allow us to increase food yields without exceeding the limits to growth. However, as a relatively new agricultural concept, much needs to be done to create an educated workforce and develop business models that ensure success.”
