Climate change, water shortage, clean drinking water, Sao Paulo, Brazil

Protests during a drought that is the worst in 80 years

Sao Paulo, Brazil, is in the midst of an untimely crisis that many claim could have been avoided – it’s running out of water, and fast. The Cantareira Water System, provides less than 5% of its capacity of 1 trillion liters. 92 other Brazilian cities have the same problem.

Not only Brazil suffers from dehydration. Recent reports from the UN’s IPCC and the White House are showing that water scarcity will hit hundreds of millions of additional people by 2100. And Tokyo is already on top of the list of world cities facing clean water supply.


Discussion about this subject did go viral started a discussion in the LinkedIn group ‘Green Cities’, which went viral in a couple of daysIn 2 weeks nearly:

  • a hundred comments from involved people gave their comments
  • people from the USA, Europe, Latin America, South Africa, India, Canada and the Middle East reacted
  • amongst the discussion members there are all kind of specialists: from entrepreneurs, architects, investors, creatives and scientists to governmental members
  • because the group happened to be ‘full’ and we heard more people would like to join the discussion, BetterWorldSolutions asked the group master to increase the amount of group members.


What’s next?

Most of the members want to take action. Not only for Sao Paulo but for a lot of area in the world. Open the whitepaper ‘Set of Actions’ in the sidebar right.

That’s why BetterWorldSolutions made an inventory of the discussion highlights, bundled the knowledge and solutions in separate sort of ‘white papers’, see right on this page.



Hopeful lessons from the battle to save rainforests


The dramatic São Paolo water supply is selected at six points. All are in single reservoir Jacarei and Jaguari, the principal of the spring. The scenes of the “before” are May 2012. The “after”, April 2014, date of the last update made by Google. That month, the  had 12% of usable volume. Now, in October 2014, is much worse: -13%.

During the rainy season Jan – March 2015, only a few drops fell in Sao Paulo

Febr 2015: catastrophic scenario

Brazil: If Brazil doesn’t have quickly, a lot of rain, states like Rio de Janeiro and São Paulo will be out of water in 2015. A catastrophic scenario in areas where millions of people live close to each other.

According to experts, the lack of rain is due to the deforestation of the Amazon and climate change. Also, Water Companies have failed to do the necessary investments, because 40% of the available water is lost because of leaking pipes.


20 million inhabitants

In the metropolis of Sao Paulo, with it’s 20 million inhabitants the largest of Brazil, the deficits have been palpable for more than a year. The crisis will spread out to other southern states like Rio and Minas because the rainy season has been nearly finished and the reservoirs are almost empty.


Brazil Government

The government has ignored the problems for a long time. Only recently they started campaigning to raise awareness about water use. Since 2015, solutions are considered at the federal level. And not just for drinking water shortage. The water crisis also leads to an energy crisis.


Dengue fever

In addition, the number of cases of dengue have increased with 50%. This increase occurs mainly in Sao Paulo, where the population keeps water in buckets and barrels for days, nothing comes out of the tap. Buckets are an ideal breeding ground for mosquitoes.
