Co-developing Indigenous seasonal calendars to support 'healthy Country, healthy people' outcomes.

In caring for Country, Indigenous Australians draw on laws, knowledge and customs that have been inherited from ancestors and ancestral beings, to ensure the continued health of lands and seas with which they have a traditional attachment or relationship. This is a reciprocal relationship, whereby land is understood to become wild/sick if not managed by its people, and in turn individuals and communities suffer without a maintained connection to Country. It is well understood by Indigenous people that if you 'look after country, country will look after you'. Indigenous knowledge systems that underpin the local care (including use and management) of Country are both unique and complex. These knowledge systems have been built through strong observational, practice-based methods that continue to be enacted and tested, and have sustained consecutive generations by adapting continually, if incrementally, to the local context over time. This paper describes a research partnership that involved the sharing and teaching of Ngan'gi Aboriginal ecological knowledge in order to reveal and promote the complex attachment of Ngan'gi language speakers of the Daly River, Australia, to water places. This engagement further led to the incremental co-development of an Indigenous seasonal calendar of aquatic resource use. The seasonal calendar emerged as an effective tool for supporting healthy Country, healthy people outcomes. It did this by facilitating the communication of resource management knowledge and connection with water-dependent ecosystems both inter-generationally within the Ngan'gi language group, as well as externally to non-Indigenous government water resource managers. The Indigenous seasonal calendar form has subsequently emerged as a tool Indigenous language groups are independently engaging with to document and communicate their own knowledge and understanding of Country, to build recognition and respect for their knowledge, and to make it accessible to future generations.
