This episode covers zone and sector analysis in a permaculture planed design is based on the Permaculture Desingers' Manual by Bill Mollison. Every plan uses zone analysis. The purpose of considering zone and sector analysis, it is primarily every-preserving for the whole site. Each component that needs more time and energy should be placed closer to the home, or zone 0. Each zone considers management of how to capture energy that is passing through the site as well, including; water, sun, wind, or even fire.

Each zone is a circle, and each circle is larger from the center.

Zone 0 (the house or the village)

This zone considers good house design. A greenhouse or glasshouse can be incorporated on the south side. Other considerations include earth-building one's home with a thatch roof, sod roof, or roof garden. While this building method can outlast modern building, it is not legally allowed in most locations. Growing components will be made of natural material and will eventually degrade, like bamboo for trellises to guide vining plants. Don't let vining plants take onto the sides of the house, which will create premature degradation and expensive to replace. Companion animals will be found in the home, although avoiding the idea of having a pet, the animal should serve a purpose within the design plan.

Zone 1

This is the most frequently visited zone and located right outside of the home, and is within 20 feet. This space has complex techniques that most arranges nature to suit out needs. The space is fully mulched and frequently worked with annual plantings that are replaced frequently for consistent harvest to serve the kitchen. Culinary herbs are also grown nearest the home to best support use in the kitchen. Chicken laying boxes will be found in this zone, but their run could be found in zone 2. In the home garden, seedlings and young trees are prepared and grown for outer zones. Mother trees may also be tended and used for grafting and cloning methods. Other animals included in this zone include fish, rabbits, guinea pigs for food production. You'll have water catchment tanks that are collected from the home's roof to be preserved and used within this zone.

Zone 2

This is less intensively managed compared to zone 1. Growing spaces will still be present, but with a focus on perennial growth instead of annual growth. Trees within an orchard or food forest will be spot mulched. Larger animals will be found here, or their shelter is located in zone 2 while their range is in zone 3. The larger animals include cows, goats, pigs, and sheep. Smaller structures will be placed here such as ponds, hedges and terraces.

Zone 3

This is the 'farm zone' where commercial crops and animals are used for sale or trade. Soil conditioning comes from zone 2. Trees are naturally growing, or little pruned in inter-planted orchards.

Zone 4

This zone is managed for wild food gathering. Plants are selected based on their volunteer and natural habitat. Wild foraging include wood gathering for wood stove fuel. Extended pasture or range will be available to larger animals. Hedge rows are used to manage the microclimate, which impacts the inner zones. Wind energy may be used to life water out of dams to irrigate the inner zone 3.

Zone 5

This is an unmanaged zone, kept wild and use for observation and meditation on the natural space. This zone is used to continue to learn the rules of nature that are present relative to the site in this zone.
