The vegetation patterns in Australia’s north are changing as higher rainfall and improved growing conditions promote the growth of native woody species and introduced noxious weeds.
The Federal Government recently established a Joint Standing Committee on Northern Australia. This move will ensure a better-informed policy making and legislative process on matters relating to the development of northern Australia.
The shortage of fresh water in the face of an increasing global population is becoming a serious issue but technological advancements in desalination could provide a significant boost to future supplies.
The importance to the global community of healthy soils is recognised each year through communication, events and activities to focus attention towards the restoration of degraded soils by increasing biodiversity, improving soil structure and enhancing fertility.
The application of modern land management practices in the sub-Sahara will present African countries with opportunities to make a positive contribution to local and global food security and to combat climate change. Smallholder farmers, however, need to be protected for the risks and financial burden of associated change.
Scientists are investigating and looking at different and innovative ways to lower levels of atmospheric carbon dioxide, a major contributor to rising temperatures leading to global warming.
Exposing plants to higher levels of carbon dioxide may enhance plant growth in the short term but, in the medium to long term, climate change threatens crop production and food security on a global scale.
Tree-planting projecsts to repair environmental damage and reforest denuded landscapes must consider multiple factors, not just the number and location of the trees .
The body of research evidence linking land clearance with increases in atmospheric greenhouse gas emissions continues to grow. Some Australian jurisdictions nevertheless, continue to promote land clearance over conservation, damaging Australia’s international climate management reputation.
