Virtuous Circles: Values, Systems and Sustainability

Our current way of providing food and other basic needs involves industrialised systems that are linear, centralised and globalised. In the linear approach, it is assumed that at one end of a system there is an unlimited supply of energy and raw materials (which there isn’t), while at the other the environment has an infinite capacity to absorb pollution and waste (which it hasn’t). The inevitable result is resource shortages on the one hand and solid waste, climate change, biodiversity loss, and air pollution problems on the other.

An alternative to the current linear paradigm is to develop productive systems that minimise external inputs, pollution and waste (as well as risk, dependency and costs) by adopting a circular metabolism. There are two principles here, both reflecting the natural world. The first is that natural systems are based on cycles, for example water, nitrogen and carbon. Secondly, there is very little waste in natural systems. The ‘waste’ from one species is food for another, or is converted into a useful form by natural processes and cycles.

This online book shows how these principles can be used to create systems and settlements that provide food, energy and water without consuming large quantities of fossil fuels and other finite resources. In the process, greenhouse gas emissions and environmental pollution are minimised whilst human well being, food and livelihood security, and democratic control are enhanced.
