Thesis abstract:

The aim of this project is to develop a replicable process for sustainable land development. The project will seek to identify public policies (for the Australian context) and economic strategies that would support the construction or conversion of village-scale communities so that they strive for socially, environmentally and economically sustainable outcomes. For the purpose of this project, sustainability will be defined and achieved by matching the village population to the carrying capacity of the land on which it is located. The aim of the proposed development process is to design and implement integrated closed-cycle systems that provide a given population with efficient living and working spaces and an abundance of water, food and energy. The systems thinking approach for planning villages begins by assessing the land and then enhancing its capacity to support a given population. The land enhancement takes the form of water cycle management, polyculture food production and renewable energy generation and distribution infrastructure. The project will include a theoretical development of the circular economy as an economic system and implementation through a prototype ecovillage. The project seeks to demonstrate that by matching supply with demand and providing an abundance for a given population, the economic problem is solved without the need for a market. This approach has the potential to alter the economics of housing as residents will not simply be purchasing a home or a property in the sense that these concepts are currently understood. Residents will, instead, be stewards of an ecosystem. They will therefore be buying into a set of responsibilities to collectively manage the systems that provide them with their basic needs.
