From Eco-Cities to Living Machines: Principles of Ecological Design

From Eco-cities to Living Machines presents the ecologically-based working designs and prototypes of biologist John Todd and writer and environmental activist Nancy Todd. Since 1969 with the founding of New Alchemy Institute on Cape Cod, the Todds have become known world-wide for their leadership in the restoration of pure water, bioremediation of wild aquatic environments, food production, and urban design. In this new book, the Todds further develop the idea of Eco-cities, designs for integrating agriculture and flowing pure water into green urban settings and introduce Living Machines, a family of technologies for purifying wastewaters to tertiary quality effluent without chemicals. Provocative and grounded firmly in the principles of biodiversity, the Todds' work encompasses site-specific technological interventions and systems-wide ecological planners and designers, environmental economists, and systems-based engineers working to change the way we utilize production, technology, water and energy.

Biologist Dr. John Todd and writer Nancy Jack Todd have been honored with major global environmental awards, including the Threshold and Environmental Programme Award. Nancy Jack Todd publishes Annuals of Earth for the Center for the Restoration of Water at Ocean Arks International and writes widely about international environmental affairs.
