Climate Change Promises Tough Times for Asia and Africa - Report

Climate Change Promises Tough Times for Asia and Africa - Report | Arrival Cities | Scoop.it

Urbanisation is increasing rapidly, especially in the developing world, with many more people living in slums and informal settlements, Kyte told IPS from London.

 

As climate change disrupts rainfall patterns and generates more extreme weather in the coming decades, leading to poor crop yields, rural populations will flood cities. Escalating numbers of urban poor will suffer, with temperatures magnified by the "heat island effect" of the constructed urban environments.

 

Safe drinking water will also be harder to find, especially after floods, contributing to greater water-borne diseases such as cholera and diarrhoea.

Coastal regions like Bangladesh and India's two largest coastal cities, Kolkata and Mumbai, will face extreme river floods, more intense tropical cyclones, rising sea levels and very high temperatures.

 

"Huge numbers of urban poor will be exposed in many coastal cities," Kyte said.

 

"We face a huge challenge over the next 20 years to... redesign our cities to protect them from climate change," Kyte predicted, even as cities already face a huge infrastructure investment gap.

 

One trillion dollars a year needed to be invested every year by 2020 by some estimates, Kyte said, adding that "to build climate resilience into cities will take another 300 to 500 million dollars a year".

Cheap, Sustainable Water Filter Made from Seeds and Sand

Cheap, Sustainable Water Filter Made from Seeds and Sand | Arrival Cities | Scoop.it

A few research groups are looking into how to use the seeds from the Moringa tree to clean drinking water. One group, from Pennsylvania State University, is developing a special, antibacterial Moringa sand that it hopes people could easily make at home and use to filter their own water.


"The idea is that as long as people have [ordinary] sand and Moringa seeds, they can clean water," said Stephanie Velegol, a chemical engineer who is leading the Penn State research. Moringa trees are common in many water-stressed regions of Asia, Africa and South America, and one mature tree can produce as many as 15,000 seeds. 


Moringa seeds might generally prove more appealing than chlorine, which many governments now distribute to people who drink untreated water from wells, rivers and ponds.

India's millennium city a 'slum for the rich'?

India's millennium city a 'slum for the rich'? | Arrival Cities | Scoop.it
The BBC's Shalu Yadav looks at why Gurgaon, India's Millennium City, has turned out to be a failure in planning.

 

Infrastructure is in a shambles: electricity is infrequent and erratic, groundwater is declining at an alarming rate, and the sewage system and roads are decrepit. There aren't enough policemen to secure the burgeoning population.

 

A whopping 70% of the residents are dependant on ground water, which is being indiscriminately extracted despite restrictions.

 

Things are so alarming that the federal ground water authorities have warned that the water table will be completely depleted by 2017.

The sewage situation also looks dire.

 

Delhi's Centre for Science and Environment (CSE) believes that by 2021, Gurgaon's estimated 3.5m people will produce so much waste that the city will be drowning in its own sewage.

 

"Unfortunately in India, infrastructure doesn't precede development. That is why one feels that Gurgaon and many upcoming Indian cities are a failure. India needs sustainable urbanisation, " Lalit Jain, chairman of the Confederation of Real Estate Developers' Association of India said.

'Huge' water resource in Africa

'Huge' water resource in Africa | Arrival Cities | Scoop.it

Scientists say the notoriously dry continent of Africa is sitting on a vast reservoir of groundwater.


They argue that the total volume of water in aquifers underground is 100 times the amount found on the surface.


The team have produced the most detailed map yet of the scale and potential of this hidden resource.


Writing in the journal Environmental Research Letters, they stress that large scale drilling might not be the best way of increasing water supplies.


Across Africa more than 300 million people are said not to have access to safe drinking water.


Demand for water is set to grow markedly in coming decades due to population growth and the need for irrigation to grow crops.
