This course focuses on how energy flows through natural systems, creating bio-geographical climate types and global weather patterns. Students learn about analogue climates, renewable energy systems, appropriate technology and permaculture design strategies specific to various climate types. Emphasis is on permaculture strategies for water management in rural or urban system. A lab introduces Keyline systems and earthworks, practical ways of assessing slope and techniques for trapping and storing energy. Tree pruning and grafting techniques are also introduced.
