Please do share what you have learned here, as it shall benefits all of us. It shall shorten our learning curve.
Mind to share your experience on your Premaculture course that you had taken?
The Permaculture course is simply a spring board into itself. There is no way everything can be covered in two weeks. For those who are interested, the real work begins after the course and this involves continuous learning because nature is just so profound in its ways. Permaculture is a marriage of two terms - permanent culture and some say permanent agriculture. Basically it's ethical design science ie. using nature to provide abundance not just for oneself but to those around and at the same time to flourish the environment. I won't go into the history of how the permaculture movement came about.
The course prepares the participants to be permaculture consultants who should have the basics to handle a permaculture project anywhere in the world. So for that two weeks, they went through practically every climate and terrain, which was overwhelming I have to admit. I went for the course just to learn more so I can apply to the climate and terrain here in the tropics. I was quite surprised at the broad range of participants. There were Americans, French, a New Zealander, lady from China, Hong Kong and another from Bangladesh. The teacher is from Turkey and he learned directly from Bill Mollison, founder of the permaculture movement. Seems I got more than what I bargained for. So, it ultimately depends on which direction one wishes to go. Some become full time permaculture teachers, others become consultants. Me, I prefer to do small time farming.
The concept can be applied to not just agriculture but at the work place, school and so on. The idea is to fully utilize an element, thus giving it more than one purpose/use. I'll give you an example. At DQ farms, no part of their chicken is wasted. The meat is eaten and sold... obviously. However, leftovers like blood is turned into fertilizer. Bones and feathers are composted back to the soil. In permaculture, livestocks are treated as working partners and not slaves or commodity. Chickens are used to prepare the land instead of manual tilling. They don't just rake up the ground, they fertilize them with manure as well. So that's an example of using an element to provide many uses.
One reason why we need so much fertilizer and pesticides is because our soil is dead. Actually here in the tropics, we have more sand than soil. Healthy soil will inevitably produce healthy crops. And in nature, trees and plants do not grow in neat straight rows. Hence, in permaculture, plants are grown in groups or 'guilds'. Another familiar term is companion planting. Before doing so, one should read up on suitable companion plants. Some plants like bamboo are allelopathic. That means they inhibit the growth of others around them. If I remember, plants of the same genus/species, get along very well. Companion planting has many benefits as some plants support each other. Some are nitrogen fixers and these tend to have deep roots and they help to bring the minerals up to the ground so when you mulch them, they feed the others with shallow roots. Someone was asking about having ladybugs to help with keeping the vegetables pest free. I've read that they love to settle down in nettles. But what do we do when we see nettles? We cut them or spray herbicide.

By the way, here in the tropics, the most efficient plants to grow would be fruit trees and for livestocks, it's aquaculture.
Permaculture promotes diverse interaction between plants and animals because that is how it was created to be. What we have done in modern agriculture is to try to turn this natural system in a factory. Of course, nature does not work like a factory. That's why we have so much issues. So we try to control it with chemicals and machines.
If you look at a modern chicken farm, you'll understand the term factory better. As chicks, their beaks are cut off so they won't peck each other as this leaves ugly marks on their skin. By the way, healthy chickens rarely peck one another because they have plenty of space to roam around. But with a broken beak, they can never live as a normal chicken and look for food like worms and insects in the ground. Well, they don't have to because they will not see a real ground anyway. They are instead kept in cages, fed with cheap grain and given hormones to make them fat in the shortest time possible. Why? To maximize profits of course. Problem is, hormones, unlike chemicals, stay in the human body. Also, these chickens are cramped together like how they cramp those foreign workers in their dormitories. To keep them alive, antibiotics are given. The air inside the chicken farm is loaded with faecal dust. That's why you'd have to wear masks before going in. But the chickens don't wear masks right? They breathe in their own poop dust every single day. So much so that it ends up in their blood. They don't get enough exercise that they can hardly stand up. But this is NORMAL as long as the farm owner is raking in profits.
Sorry for the long winded post. I hope I did not come across as some 'holier than thou' preacher. After living in the city all my life, I've concluded that our food and our life is pretty messed up. I'm still learning and hope someday, I can provide for myself, family, neighbours and community some real wholesome food.
If you have time please watch this video. It's one of the best I've seen on urban permaculture. I really envy this couple.
