Many people believe that we are soon to face a global food shortage. Population is rising rapidly, with a billion people added in less than ten years. 40% of farming land has been depleted  and rainforests have been cut down to make more room for farming. Farmers are moving into cities at the rate of over a million a week ^[1], and our appetite for meat is growing^[2]. These trends means that food demand is rising, but there are fewer farmers to supply it, while the basis of our agricultural production is under strain. It would indeed seem that we are heading for a food crisis.

But this story misses a key point: there are far better ways to produce food than the ones now in wide use. While it is true that conventional plough agriculture and monoculture is driving the world towards a food crisis, there are ways to grow food using very little land, very little labour and no pollution. The aim of this page is to explore these methods and show how they can comfortably sustain a growing population. Any food shortage is really a shortage of applying this know-how to food production.

It is possible, with current know-how, to create a food-production system that can provide tens of billions of people with abundant, local, nutritious, tasty food, textiles and wood, while economizing water, restoring soil, building communities, saving energy, creating pleasing landscapes, preserving wilderness, stopping diseases, needing virtually no inputs and benefiting not just people, but the rest of the biosphere as well.
