Permaculture is a design system that aims to create sustainable human environments. Its primary goal is to create productive and resilient ecosystems that can provide for the needs of humans and other organisms.

Diversity, interconnectedness, and feedback loops are all key principles of permaculture. Diversity refers to the variety of plants and animals in a system. Interconnectedness refers to the way that different elements of a system are connected and interact with each other. Feedback loops refer to the way that information flows through a system and is used to make adjustments.

Forest gardening is a permaculture design that mimics the natural patterns of a forest ecosystem. It involves planting a variety of trees, shrubs, and groundcovers in a way that creates a self-sustaining system that provides food, shelter, and other resources for humans and other organisms.

Rainwater harvesting, swales, and terraces are all common permaculture techniques for managing water. Rainwater harvesting involves collecting and storing rainwater for later use. Swales are shallow ditches that are used to slow down and infiltrate rainwater. Terraces are earthen embankments that are used to control erosion and conserve water.

Silvopasture is a permaculture design that integrates livestock and trees. It involves planting trees and shrubs in pastures where livestock graze. The trees and shrubs provide shade and shelter for the livestock, and they also help to improve the soil quality.

Companion planting, crop rotation, and biological pest control are all common permaculture techniques for reducing the need for pesticides. Companion planting involves planting different types of plants together in order to benefit each other. Crop rotation involves planting different crops in the same area in a sequence in order to break the life cycle of pests and diseases. Biological pest control involves using natural enemies to control pests.

Food forest, keyhole garden, and hugelkultur are all permaculture designs that create self-sustaining ecosystems in small spaces. Food forests are designed to mimic the natural patterns of a forest ecosystem, and they can provide a variety of food, shelter, and other resources for humans and other organisms. Keyhole gardens are small, circular gardens that are easy to maintain and can be used to grow a variety of vegetables and herbs. Hugelkultur is a method of creating raised beds using logs and other organic materials.

Composting, mulching, and cover cropping are all common permaculture techniques for improving soil fertility. Composting involves breaking down organic materials into a nutrient-rich soil amendment. Mulching involves covering the soil with a layer of organic material, which helps to retain moisture and suppress weeds. Cover cropping involves planting a crop that is not intended to be harvested, but rather to improve the soil quality.

Aquaponics is a permaculture design that integrates aquaculture and agriculture. It involves raising fish and plants together in a symbiotic system. The fish provide nutrients for the plants, and the plants help to clean the water for the fish.

Passive solar design, earth sheltering, and green roofs are all common permaculture techniques for reducing energy consumption. Passive solar design involves designing buildings to take advantage of the sun's heat. Earth sheltering involves building structures into the earth, which helps to regulate temperature and reduce energy consumption. Green roofs are roofs that are covered with plants, which helps to insulate buildings and reduce energy consumption.

Ecovillage, co-housing, and intentional community are all permaculture designs that create sustainable communities. Ecovillages are communities that are designed to be self-sufficient and sustainable. Co-housing communities are designed to share resources and facilities. Intentional communities are communities that are formed around a shared set of values and goals.

Composting, recycling, and reusing are all common permaculture techniques for reducing waste. Composting involves breaking down organic materials into a nutrient-rich soil amendment. Recycling involves turning waste materials into new products. Reusing involves using items multiple times instead of throwing them away.

Food forest, keyhole garden, and hugelkultur are all permaculture designs that create sustainable food systems. Food forests are designed to mimic the natural patterns of a forest ecosystem, and they can provide a variety of food, shelter, and other resources for humans and other organisms. Keyhole gardens are small, circular gardens that are easy to maintain and can be used to grow a variety of vegetables and herbs. Hugelkultur is a method of creating raised beds using logs and other organic materials.

Planting a variety of plants, creating wildlife habitat, and using native plants are all common permaculture techniques for increasing biodiversity. Planting a variety of plants helps to create a more diverse and resilient ecosystem. Creating wildlife habitat provides food and shelter for a variety of animals. Using native plants helps to support local ecosystems and biodiversity.

Rainwater harvesting, swales, and terraces are all permaculture designs that create sustainable water systems. Rainwater harvesting involves collecting and storing rainwater for later use. Swales are shallow ditches that are used to slow down and infiltrate rainwater. Terraces are earthen embankments that are used to control erosion and conserve water.
