What is permaculture? It is a 'science of design', meant to create a truly sustainable living. It is a way to design and implement productive, self-sustaining systems, which do not require drudgery. For a good but short overview, take a look here. If in conventional farming the owners must work very hard every single day of their lives, permaculture farms aim to decrease this modern slavery over time by mimicking nature. With every passing year, a permaculture farm will be more productive and resilient and require less maintenance. The best go-to example is what is called a food forest - a forest made of fruit and nut trees, with a mix of interplanted berries and vegetables. The trees and most of the understory is perennial, and annual vegetables and flowers are allowed to reseed themselves freely, thereby minimizing maintenance. Compare that to a field of wheat that needs ploughing, seeding, and several applications of pesticides to make it through the growing season.
How is this low-work-high-awesomeness accomplished? By a mix of approaches -
- Managing rainwater to provide for future irrigation needs and eliminate soil erosion
- Not turning the soil (i.e., no digging, tilling, ploughing) and not using pesticides ensures that all soil organisms, whether earth worms, bacteria, or fungi, are alive and well. Successful agriculture requires happy and living soil.
- Mulch, mulch, mulch - both protects the soil from erosion and retains moisture and nutrients.
- High plant diversity (big no-no to monoculture) to ensure ecosystem stability, as different plants provide different services - attracting pollinators, deterring pests, pulling nutrients into the top soil via deep roots, breaking up tough soil using root vegetables, etc.
- And the biggie - observe your own piece of nature and conform to it. Work with nature, not against
ither. Arid areas should have mostly drought resistant plants; cold areas should rely on hardy varieties. Growing things that can't make it themselves will mean endless, futile, work for the farmer.
The principles really appealed to us - planning things well, healing the soil and creating an ecosystem while growing our own food, and ensuring increased yields through decreased work sounded fantastic. I spent a few of the following months reading all I could get my hands on and dreaming about our own Garden of Eden (see below for a preliminary design).
