No government can make it rain, but this government is enacting a three-point plan to put the Murray!Darling Basin back onto a sustainable footing: 1) We have taken over Basin-wide planning and for the first time will place a scientifically-based cap on Basin water use. 2) We are investing in irrigation infrastructure to help our farmers and Basin communities and to protect food security. 3) We are buying back water to help restore health to the Basin’s rivers and wetlands. To protect our biodiversity and use Australia’s natural ustralia’s natural environment, our biodiversity and the resources wisely, Caring for our Country, the Australian Aecological services it provides, underpin our quality of Government’s environmental management initiative, targets life, our economy and much of our national identity. We are clear national priorities and measurable outcomes. This one of the world’s 17 mega-diverse countries, with more includes recognising aquatic ecosystems as significant endemic animal species than any other country. However, environmental assets that provide a wide range of services places such as the Great Barrier Reef and Kakadu National which are fundamentally important to the Australian lifestyle Park, which are ecosystems of international significance as and economy. These national priorities are designed to well as part of our national identify, are at risk from climate make a real on-ground difference to wetland health, and change. ensure that funding goes to those areas and projects across the nation that best meet the ecological challenges we face. Climate change is one of the greatest economic, social, and environmental challenges of our time, but the Government Wetlands are a critical part of our natural environment. They is meeting that challenge. We are getting on with the job protect our shores from wave action, reduce the impacts of of preparing for a future with less water. A drying climate floods, absorb pollutants and improve water quality. They and rising demand for water means added pressure on provide habitat for animals and plants and many contain a Australia’s rivers and wetlands. A high proportion of species wide diversity of life, supporting plants and animals that are – about 85 per cent of terrestrial mammals, 91 per cent of found nowhere else. It is vital that these critical ecosystems flowering plants and 90 per cent of reptiles and frogs found and their biodiversity are maintained, protected and given only in Australia – are also potentially at risk due to climate resilience to meet the challenges of climate change. change.
