Cyclone Idai hit poor countries the hardest and shows why disaster resilience is a necessity.
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.
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.
Australia's subtropical regions are drying, but if we can slow the global temperature rise then rainfall should increase again.
There are regions in South Africa where it hasn't been established if the rainy season is in summer or winter.
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.
Despite its global importance, the rainy 'Maritime Continent' around Indonesia is hard to capture using global climate models. But fear not - new research shows how to improve our forecasts.
South Africa is a water stressed country but crisis point can be avoided.
Uncontrolled growth at the expense of the environment will severely exacerbate the impacts of climate change. As shown with tragic floods in India, our cities are not prepared for extreme events.
More than 350 people have died after intense rainfall in the Indian state.
Southern Australia's debate may be exacerbated by climate change, but it's not that simple.
An annual assessment of the health of Australia's environment shows mostly stable conditions in 2017, but ecosystems on land and at sea suffered ever higher temperatures.
Engineering practice assumes that floods are randomly distributed but science suggests they are not. This raises questions about the reliability of flood infrastructure and management strategies.
In periods of water stress, farmers need support, research assistance and empathy from governments and competing water users.
We think of Canada as a water-rich country, but we are not immune to water shortages or disasters. With some advance planning, Canada can avoid a water catastrophe.
It was the Seine’s rise and fall, in response to heavy rain, that inspired our current understanding of river systems.
The experiences of other countries can provide valuable lessons for Cape Town on how to better cope with its water crisis.
The water crisis in South Africa's Cape Town teaches us there's more at play than just rainfall. Disasters like droughts means the issue must be seen from many different perspectives, like politics.
Satellite research in Ethiopia is opening up a new frontier in the hunt for geothermal power.
It's wrong to blame climate change for famine and conflict. These can either be prevented, or the impact minimised, if institutions and mechanisms of good governance are in place.
