Permaculture 102 - Permaculture Design Part 2: Assessing an Urban Garden's Potential Based on Sun Angles, and other Sources of Natural Energy.

---

Following on from Part 1 (in which we identified the layout of the property, prepared the aerial diagram and made some initial interpretations from both the diagram and by doing a little research into the general area’s climate), Permaculture Design Part 2 gives us the first look at real Permaculture thinking - the Sector Analysis of the space.

We'll look at what is outside the design area but has an impact on it – I.e. the channeling, or alternately protection from, one of nature's energy sources – wind, sun, fire, water, frost.  One of these will often represents a dominant force in a design – e.g. the sun – pretty dominant in Perth!

This step will give you an idea of the seasonal changes occurring within the block and hence the heat/solar energy, air flow, fire risk, water delivery opportunity/problems, or chill locations that need to be worked with.  Whilst we will cover this at a very high level here, we'll get into much more detail on all of these forces within future blogs as we step onsite and find examples to explore!.  This information will help you assess (a) what plants will survive and thrive in different areas of the garden all year round and for many years to come (perennials); (b) which spaces should be dedicated to annuals (with alternate season options too!); and (c) where we can look at creating new protection systems to extend the time an area is suitable for growth (E.g. the addition of a deciduous tree or a wind guiding bank of plants).   ENJOY!
