High poverty levels mean people lack access to land and work and they are often driven to settle in zones that are exposed to natural hazards.
The Indian summer monsoon rainfall affects the lives of over a billion people. By looking at how prehistoric climate changes affected it, scientists can contribute to its future prediction.
Q fever is a flu-like infection that spreads to people from animals. The bacteria that causes it can withstand harsh environmental conditions – in particular, drought.
A new petition is urging state and federal governments to rein in Australia's rampant land clearing, which worsens the risk of bushfires and threatens to undo the work of the Emissions Reduction Fund.
With heatwaves, droughts and fires all on the rise, the federal government is urged to merge its separate strategies on disaster resilience and climate readiness.
If the pattern of drought continues in South Africa it's likely to affect the country's financial standing too.
Australia's farming industry will need to take full account of its obligations to its workers, its customers, society and the environment if it is to prosper in the years to 2030.
Cape Town's draft strategy on water supply is out for comment, but important elements are missing from it.
Australian wheat growers need to boost yields to stay competitive in the face of climate change. They could do this by sowing earlier, but need new varieties of wheat to help them do it.
A combination of reasons have led to the drying of the Sahel.
We can't make it rain. But you are already helping if you don't use more water than you need. And you can talk to your parents about the planet getting warmer, because the heat makes drought worse.
Cities relied entirely on conserving and recycling water to get through the last big drought. We now have desalination plants, but getting the most out of our water reserves still makes sense.
Australia's subtropical regions are drying, but if we can slow the global temperature rise then rainfall should increase again.
Sydney and Melbourne are bringing desalination plants back on stream and Adelaide plans to increase its plant's output. Perth depends on desalination. But is it the best way to achieve water security?
Freshwater fish are suffering as drought becomes more common and severe. Whether they survive will depend on how governments manage rivers and lakes, and on taking action against climate change.
New satellite-based research shows there is at least as much value in knowing how much water is left for plants to use as there is in knowing how much rain may be on the way.
Banking water minimises the impact of evaporation and means that water can also be recycled from various sources.
A decade of bipartisan research has provided plenty of answers to the problems plaguing the Darling River.
Forests in the US face many threats: climate change, invasive species, pests and pathogens. Could genetically engineering trees make these plants more resilient?
Mass fish deaths are a blaring warning sign for the heath of the Murray Darling Basin, but just as worrying is the sight of dry areas in the Darling.
