- Seaasons of Change: Nature vs Calendars
Seasons are more than just the changes in weather, ecology and hours of daylight caused by the Earth’s rotation around the sun and the gentle tilt of the Earth’s axis. Astronomers and meteorologists are at odds, and in Australia the conventional “Vivaldi” seasons are found wanting. Seasons affect people and people, plants and animals are intimately connected with their own seasonal understanding.
I speak with Professor Tim Entwisle, Director of the Royal Botanic Gardens, Victoria and author of Sprinter and Summer : Australia’s Changing Seasons. He has considered the natural biological responses of plants in particular and proposed, as a discussion paper, the inclusion of an additional “season” into our horticultural calendar.
Dr John Ryan from Edith Cowan University is an environmental philosopher and considers that an understanding of the indigenous weather calendar is essential to a deeper understanding of all disciplines in particular localities. He has followed the development of the Indigenous Weather Knowledge Project by the Bureau of Meteorology, a compilation of indigenous seasonal calendars around Australia.
