7 Climate Change & Site Analysis
Where Am I?
There are recurring characteristics in every climate that will affect the land, and what can grow and live there. These recurring characteristics are called climatic patterns. By understanding climatic patterns, you can incorporate the characteristics into your plan, use them to inform your choices and create a more effective permaculture design.
In this book we will focus on Earth’s three major climate zones (climate types). There are many more then 3 climate zones; the Earth is an incredibly diverse place with great variability! But for the purposes of the introductory book we will look at the three most general categories: Tropical, Drylands and Temperate zones. Let’s take a closer look at these now, and explore the climatic patterns of each one.

The Effects of Climate Change
The climate is changing and weather extremes are increasing throughout the planet. Changing climatic patterns can have an effect on native plants, animals, weather, temperature, agriculture, sea levels, energy use, and much more. A Permaculture design is “permanent” because it is planned around resilience to extreme weather events. A Permaculture designer studies historical and projected weather events, and uses these to make informed design choices. Understanding weather and climate are important for the designer to have all the information to make the best design choices.

What Will You Do?
Ask yourself “What are the major climatic patterns that determine the conditions which I will respond to with my Permaculture designs? How are my design parameters potentially affected as the climate changes?”
