The Murray-Darling Basin is a large geographical area in southeastern Australia, covering over one million square kilometers. It includes the Murray River and the Darling River, which are vital water sources for agriculture and communities in the region. The basin supports diverse ecosystems and is home to various plant and animal species. The basin is crucial for Australia's economy, particularly in agriculture, as it produces a significant portion of the country's food. Water management in the Murray-Darling Basin is essential due to challenges like drought, climate change, and competing water demands from urban and rural users.
