Greater urban density is making it harder to preserve, let alone increase, tree cover. It's vital, then, to demonstrate the full value of green infrastructure for healthy liveable cities.
South Africa needs to develop low-cost housing solutions that are inherently comfortable and environmentally sustainable. Green roofs could be part of these solutions.
Hot weather kills more Americans yearly on average than floods, tornadoes or hurricanes. Three scholars explain how cities can prepare and help residents stay cool.
Rather than mourn the end of a seven-year reign as 'world's most liveable city', Melbourne could raise its sights to become more liveable, healthy and sustainable for all who live in the city.
Urbanisation is the main reason for rising temperatures and water pollution, but receives little attention in discussions about the health of water streams, reefs and oceans.
Australia's coastal settlements are highly exposed to the impacts of climate change. Climate-resilient urban landscapes that can cope with large amounts of water need to become the new normal.
Darwin's climate is getting even hotter and it's one of the main reasons people leave the city. A lot more can be done, though, to make our tropical cities safe, cool and enjoyable.
Taking this step may improve the quality of life for vulnerable people and reduce the amount of air conditioning they use, making their neighborhoods less prone to power outages.
Energy experts are getting excited about a proposed solar farm in Kent and what it could mean for a clean energy future.
July is the hottest month in much of North America. Experts explain who is most affected by heat waves and ways to cope with them.
Dense, high buildings limit the space available for urban greenery. But imaginative projects that involve the community can ensure nature and the city go hand in hand.
Research shows if Australia encourages greenery on buildings, it will reduce temperatures in the city, as well as potential for flash flooding. It also creates new habitats and socialising spaces.
How to move beyond the warm words about tackling urban heat islands to doing something about them.
In the future, Europe will suffer from more heat waves as well as extreme rainfall, presenting new challenges for planners and health care services. Building resilient cities can help.
The Australian Open tennis and the recent Ashes Test cricket series show why our sporting stadiums need to be "climate-proofed" to deal with extreme heat.
Sun, wind, waste biomass, geothermal, tides and waves: all these energy sources in Sydney's backyard add up to a zero-carbon energy solution for the city.
Urban bees deal with what's known as "habitat patches," discontinuous patches of green like gardens, parks and ravines. Green roofs could offer relief to bees dealing with habitat fragmentation.
Green roofs could play a critical role in helping cities cope with extreme rainfall events in the age of climate change. The roofs essentially suck up stormwater like sponges if designed properly.
Greening cities have a huge impact. The trees go beyond just lowering temperatures. They help decrease the demand for indoor cooling like air-conditioners saving money.
The US wants to invest in more infrastructure to handle our rainfall and melted snow. Stormwater credits could help cut costs and protect the environment.
