You already know about the non-sustainable techniques of mono-cropping, fertilizers, pesticides, and agricultural scale irrigation have on the environment and quality of the food we eat. And most industrial organic practices are not much better. Permaculture (permanent agriculture) is a resilient means to take control of your own food supply and design our yards and farms to be more sustainable in terms of energy, water, materials, food production, and so much more. The presentation will provide an overview for many of the applied uses for permaculture design including garden design, seed sowing, mixed planting (polyculture), companion planting, alternatives to irrigation (even eliminating irrigation in desert climates), food production, and more.
You have already been bombarded with what the problems are. This presentation is about the solutions.
From Wikipedia : Permaculture is an approach to designing human settlements and agricultural systems that mimic the relationships found in natural ecologies.
Permaculture is sustainable land use design. This is based on ecological and biological principles, often using patterns that occur in nature to maximise effect and minimise work. Permaculture aims to create stable, productive systems that provide for human needs, harmoniously integrating the land with its inhabitants. The ecological processes of plants, animals, their nutrient cycles, climatic factors and weather cycles are all part of the picture. Inhabitants’ needs are provided for using proven technologies for food, energy, shelter and infrastructure. Elements in a system are viewed in relationship to other elements, where the outputs of one element become the inputs of another. Within a Permaculture system, work is minimised, “wastes” become resources, productivity and yields increase, and environments are restored. Permaculture principles can be applied to any environment, at any scale from dense urban settlements to individual homes, from farms to entire regions.
Permaculture as a systematic method was first practised by Austrian farmer Sepp Holzer in the 1960s and then scientifically developed by Australians Bill Mollison and David Holmgren and their associates during the 1970s in a series of publications.
The word permaculture is a portmanteau of permanent agriculture, as well as permanent culture.
The intent is that, by rapidly training individuals in a core set of design principles, those individuals can design their own environments and build increasingly self-sufficient human settlements — ones that reduce society's reliance on industrial systems of production and distribution that Mollison identified as fundamentally and systematically destroying Earth's ecosystems.
While originating as an agro-ecological design theory, permaculture has developed a large international following. This "permaculture community" continues to expand on the original ideas, integrating a range of ideas of alternative culture, through a network of publications, permaculture gardens, intentional communities, training programs, and internet forums. In this way, permaculture has become a form of architecture of nature and ecology as well as an informal institution of alternative social ideals.
