There is a world in which humans integrate into the water-nutrient cycle. Welcome to Greenway, an achievable, sustainable vision from Earle Barnhart and Hilde Maingay.
Greenway is a vision of an ecological neighborhood, where basic needs – food, water, shelter, transport, communications – are provided in ecologically sustainable ways with renewable energy. It’s a network of homes, greenhouses, garden, and businesses, connected by sheltered corridors. Housing is integrated with agriculture. Biology is integrated with technology. People are integrated with the cycles of the Earth.
Greenway – then & now
New Alchemy Institute first explored the concept of bioshelters from 1970 to 1990, including design, research and testing of prototypes.
Among our major tasks is the creation of ecologically derived human support systems – renewable energy, agriculture, aquaculture, housing and landscapes. The strategies we research emphasize a minimal reliance on fossil fuels and operate on a scale accessible to individuals, families, and small groups.
– Bulletin of the New Alchemists, Fall 1970
How do we get to Greenway?
The Greenway is a blueprint for a next-generation bioshelter. Its eco-architecture includes housing, a close connection to outdoor agriculture, and recycling of food nutrients, designed at a community scale. It is a realizable vision of a sustainable habitat for humans on this planet.
Environmental refugees will need to be housed in new, well-designed, low-energy inland villages or self-reliant settlements, minimizing transport and fossil fuel uses.
Bill Mollison, Permaculture, 1988
Greenway infrastructure is well-suited to provide housing and basic needs to people displaced by climate change, without adding emissions. The architecture is decentralized, but is also interconnected to facilitate travel and communication. It is modular, to allow for mass-production and rapid assembly.
By integrating housing with food production and community-scale utilities, this eco-infrastructure has the potential to 1) provide humane shelter and security for climate refugees and 2) replace the climate-destroying industrial infrastructure that supports our current society.

Follow the Water

Follow the water through the Greenway to a more sustainable way of life. Rainwater from the roof is collected inside, where it passes through aquaponics ponds, is used to store solar heat, and then is used to irrigate indoor and outdoor gardens. Some rainwater water is purified for drinking and cooking. After multiple uses the water is evaporated back to the sky by plants or is released into the environment as unpolluted groundwater.
