Permaculture is a branch of ecological science which develops sustainable architecture and self-maintained horticultural systems modeled from natural ecosystems.The design principles which are the conceptual foundation of permaculture were derived from the science of systems ecology and study of sustainable land use. Permaculture draws from several disciplines and has been applied most commonly to the design of housing and landscaping, integrating techniques such as agroforestry, natural building, and rainwater harvesting within the context of permaculture design principles and theory (source: wiki mod).
On the web I have found The Permaculture Research Institute of Australia that work with individuals and communities worldwide to expand the knowledge and practice of integrated, sustainable agriculture and culture using the whole-systems approach of permaculture design. This will provide solutions for permanent abundance by training local people to become leaders of sustainable development in their communities and countries (source http://www.permaculturenews.org/about mod). very interesting web site, join it!!!!
.... and what do you think? do you think the treatment wetlands may not be a suitable systems? OHHH YESSS, take a look to the australian research site, you will find a good read about treatment wetlands. I want to mention them with his words reported below:
"These artificial wetlands provide a near zero energy input way to treat local effluent with no negative side effects. The process is free of both chemicals and odours, provides habitat for wildlife, increases the diversity and aesthetics of any site, and, depending on the toxicity of the inflowing effluent, can potentially create a yield, such as fodder for livestock."
very good words! congratulations
