According to a recent news article released as a press release by the American Geophysical Union (AGU) it has been noted that half of the world’s annual precipitation falls in just twelve days according to global weather stations.
Notably, in light of climate change such precipitation may even be changed further to occur in just eleven days, amplifying flooding and its associated damages.
Recently news stories highlighted the plight of Cape Town and “Day Zero” with their taps expected to run dry in April 2018. Fortunately, due to reservoir levels rising consistently and adequate water restrictions in place that day is not expected for any time in 2018 or 2019.
Yet, one country which is currently experiencing issues with their water supply is El Salvador, namely in rural villages such as Cabanas, and the municipality of Nejapa, as well as, poor neighborhoods in the capital of San Salvador.
Thus, with contaminated surface water supply, depleted groundwater reserves and the effects of climate change many are expected to be affected by a lack of potable water.
The latest issue of the EOS Earth & Space Science News magazine published by the American Geophysical Union (AGU) is now available for perusal.
This issue presents information on topics such as climate change forecasting, modeling Beijing’s water crisis, changing rainfall patterns, Alaskan earthquakes, warmer Arctic temperatures, coastal zone change, geophysical maps and more relevant American Geophysical Union (AGU) news.

In this latest article from Janice Kaspersen, from the Stormwater magazine, by Forester Network, one gets a look at “China’s sponge cities” and how they choose to rectify their water related problems of stormwater runoff and flooding.
You may have read recently about China’s “sponge cities.” They’re an approach to what we commonly call green infrastructure—an attempt to reduce flooding and infiltrate stormwater runoff in some of the areas most affected by rapid urbanization. China has spent $12 billion so far—with federal and local governments and private developers all contributing—in about 30 different cities to install measures such as permeable pavements, bioswales, green roofs, and wetlands.
Flooding has become a deadly problem in China, especially in major cities. As this Economist article notes, the country’s urban land has more than doubled in the last 20 years, and cities sometimes expand right into the floodplains. “All this is exacerbated by China’s often impetuous approach to urban planning,” the article continues. “When the planners in charge of Beijing designed its roads a few decades ago, for example, sunken underpasses were chosen over elevated interchanges for the reason that they seemed more appealing visually, as well as being cheaper to build. They have also, as it turns out, become a particular source of sodden misery. Beijing has 149 such underpasses in its urban districts. With inadequate drains and pumps, even a single heavy rain can turn them into swimming pools, bringing traffic to a halt in the process.”
