Cape Town’s new water map shows users who are within the water restriction limit.
A drought levy is being proposed for water scarce Cape Town. The levy is facing wide opposition and there are claims it’s punitive and punishes those trying to save water.
By 2050, climate change impacts such as storms and drought could displace up to 300 million people worldwide. Nations should recognize ‘climate migrants’ and make plans for aiding and resettling them.
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.
Low flows in the Murray River in recent years have harmed tiny marine plants called phytoplankton, with consequences for local marine species and management.
Water is increasingly becoming scarce as the climate changes. There are four changes that cities can make to adapt to water scarcity.
There are a number of myths surrounding Cape Town’s drought, one of them being that the city saw the crisis coming but didn’t prepare for it.
Cape Town promised alternative water sources with the ongoing drought being declared a disaster. Its main strategy is water rationing but climate models are also being used.
It’s important for the city of Cape Town to inspire residential trust in water restrictions. Without this, the harsh effects of the drought will be exacerbated.
Dry areas make up more than 41% of land around the globe and are home to more than two billion people. Despite climate change and other challenges, there are ways to combat land degradation.
There is increasing evidence from across many African and South Asian countries that contextual, timely climate information, helps farmers manage the risks they face.
Historically low rainfalls have led to severe droughts in Somalia, Ethiopia and Kenya. But various solutions exist to mitigate the social and economic impact.
Smart meters may help water saving initiatives as the drought persists in South Africa’s Western Cape. It can help those who need achieve saving targets.
Desalination has been proposed as one of many strategies to deal with the water shortages. But the process is known to be expensive and harmful to the environment.
Early warning signs of a pending drought are difficult to recognise but cities will have to be better prepared for prolonged changes in weather patterns, so that it can respond quickly.
Too much emphasis on environmental stress overlooks the role of politics and economics.
Windhoek can teach Cape Town on dealing with drought. Technology alone is not enough.
