Back to 2011 I wrote about Isang Litrong Liwanag, a Filipino iniative to bring light to people living in the slums of Manila. Years laters, the project has grown, found partners and is expanding globally.
This was the question asked on the the Yale Environment 360 blog and I believe the timing is perfect as last year cities such as New York City, Manila and Bangkok got it by record floods. Now it is the turn of Jakarta.
The capital megacity of Indonesia now has water in its streets and people to evacuate because of another flood. Given that rising temperatures mean rising sea levels and more extreme weather, the threat is huge.
First in terms of people – as the majority of people will live in cities in 2050 and as 14 of the world’s 17 largest cities are located along coasts.
Manila, Jakarta and Kolkata (formerly known as Calcutta) would be threatened the most. Others cities, including Mumbai (Bombay), Delhi, Chennai, Karachi, Lagos and Guangdong, would also be in danger.
This reminds me of a series of posts I had published here as early as 2008 on that very subject. This time, the research had been carried out by the OECD and the World Bank.
While reading the tweets of the people I follow, one from Andrew Revkin got my attention : “ H. sapiens, innovator: Solar “light bulbs” from water-filled soda bottles brighten tin-roofed slums. “
This was how I got introduced to Isang Litrong Liwanag ( “A Liter of Light” ), one of the most brilliant ideas I came across while writing for this blog. The tweet was followed by a link to a Youtube video – watch it below.
