In 2013, Tanunda Lutheran School commenced their Sustainable Outdoor Learning Environments (SOLE) program. The program aims to foster a culture that helps the school develop an inspiring educational model that embraces environmental, social, and economic sustainability. The school had a good grasp on how to manage the required change within the social and educational domains of the school, but had no internal expertise to help plan for the sustainable development of their site.
The school wanted to think more broadly than a single program, such as the development of productive food gardens. They instead opted for a whole-of-school approach which considered land, water, energy, biodiversity, site efficiency, horticulture, outdoor education, aesthetics, and nature play.
