It is the deliberate creation and management of agriculturally productive systems with natural ecological diversity, stability, and resilience. It is the sustainable integration of the landscape with people supplying food, energy, shelter, and other material and non-material requirements. Permaculture is a concept and approach to land management that is based on the arrangements seen in healthy natural ecosystems. It consists of a set of design ideas drawn from whole-systems thinking. It applies these principles to regenerative agriculture, rewilding, and community resilience, among other things. Permaculture  is different from organic farming in a way that organic Farming promotes the use of natural fertilizers, making use of the natural carbon cycle so that waste from plants becomes the food (fertilizer) of another but permaculture brings production of food closer to consumers and the consumer's wastes back into the cycle.

It seeks to look at a piece of land as a whole, incorporating all of the animals and plants that live there, as well as social systems that promote long-term agriculture. Each component of the food cycle is dissected into what it requires and what it gives, and then each component is stitched together to make a dynamically self-sustaining whole. Permaculture is gaining popularity as industrial food systems become increasingly threatened by a variety of issues, ranging from pests attacking monocultured crops to rising prices and limited supplies of the fossil fuels required to produce and transport industrial food. Permaculture is being embraced by communities as a means of ensuring not only the health of the land they live on, but also the health of the people who live there. It is based on three ethical principles: environmental stewardship, human stewardship, and equitable distribution. They are at the heart of permaculture design and may be found in most traditional communities. Simultaneously, permaculture evolves beyond a mechanical collection of rules for the management of all cultures that may be applied to the creation of long-term system .The important principles of permaculture are:

1) observe and interact

We may learn from nature and from other people by observing how others have progressed toward more environmentally friendly and ethical approach, and by collaborating with the world around us to achieve our objectives.

2) catch and store energy

Growing your own food at home is an excellent way to capture and store solar energy. Passive solar architecture also allows architects, engineers, and designers to take advantage of this abundant energy source in new ways.

3) obtain a yield

Living a sustainable lifestyle based on permaculture principles can provide us with a variety of intangible and tangible benefits in addition to the obvious concrete ones.

4) Apply self regulation and feedback

Understanding where we've succeeded and where we've failed is critical to making significant, long-term change. By analyzing and evaluating everything we bring into our houses, for example, we can make better purchase decisions in the future: minimizing, reusing, recycling, and curbing our worst consumerist tendencies.

5) use and value renewables

By using the power of the sun, the wind, or the water, we can power our homes, grow our food, and regenerate our environments.

6) produce no waste

Moving toward a zero-waste lifestyle entails examining all of the garbage we produce and attempting to remove it. We can accomplish this by decreasing the quantity we spend, purchasing wisely, reusing or recycling when possible, composting, and partnering with ethical companies that consider waste throughout the product's life cycle.

7) use small slow solutions

Moving toward a zero-waste lifestyle necessitates assessing and attempting to eliminate all of the junk we make. We may do so by reducing our spending, making prudent purchases, reusing or recycling when possible, composting, and cooperating with ethical companies that consider waste throughout the product's life cycle.

8) Design from patterns to details

We must consider the big picture before getting mired down in the details, whether we're creating a new vegetable garden or an entirely new sustainable way of living.

9) use and value diversity

Similarly to how ecosystems thrive when a diverse range of plants and animals are present, human civilization thrives when a diverse range of individuals are represented.
