Case studies of real world functional landscapes - created using permaculture design principles

Permaculture PhD Research:

Case studies of real world functional landscapes - created using permaculture design principles.

Assessing Regenerative 'Low-Entropy' Systems, for increasing the sustainability of wastewater purification and resource production, compared with the performance of conventional 'High-Entropy' Systems for wastewater treatment.

Since 1993 Biologic Design, a Herefordshire based Permaculture Design Company, has created site-specific water purification and habitat enhancement systems (known as Wetland Ecosystem Treatment (WET) Systems).

These systems use ecological processes in order to purify wastewater, harvest rainwater, provide local renewable resources and enhanced resilience, improve biodiversity, and reduce reliance on electricity.

It has become clear that the benefits of the low-entropy WET System approach have never been fully quantified, nor been subjected to an objective external appraisal for their positive environmental impact.

The research will categorise the environmental benefits of the WET System, in order to determine the impact of such systems in comparison with alternative ‘default’ methods, such as conventional machine-based sewage treatment.

The research will look intensively at several established systems and assess the use of ecological (permaculture) design and biological engineering techniques; using their energy requirements, yields, the economics (cost/benefit), biodiversity and resilience and use of or production of resources.
