When it comes to ecological architecture, we often come across the word permaculture. Permaculture means design and cultivation in harmony with nature. The term includes not only natural architecture, but also gardens that self-regulate like in the wild. It is a new type of agriculture that doesn’t use chemical fertilizers and doesn’t plow the soil. Mulching is used like in a forest. Mulch is a source of natural fertilizer. Wood cuttings, twigs, manure, hay, nitrogen-rich green plants, compost plants and straw are used to make it. There is no sterilization of the soil or water pollution in permaculture. Ecovillages are self-sufficient, because the inhabitants have their own food: they grow vegetables, fruit, and herbs; instead of lawns they have meadows with wild edible plants, they build fish ponds, create orchards, take care of forests, and keep animals. They have their own solar and wind energy sources, biological sewage treatment plants, and rainwater recovery installations. There are several zones in a farm design: 0.house and its surroundings, 1.zone closest to the house, where annual plants that require more attention are grown, 2.perennial plants that can be looked after less often, 3. zone of root crops (potatoes, beets , corn), 4. semi-wild zone, where timber and mulch are obtained, 5. wild zone, forest ecosystem without human interference.
