“Why would I want to?” Because in poor countries, chickens are everywhere, they are pooping wherever they want, and chicken feces is dangerous for young children.
2016 has become the year for water. From the World Economic Forum, COP22, to the Budapest Water Summit, water has been widely acknowledged as a key to achieving the Sustainable Development Goals, and essential to the climate change solution.
Here are the defining moments of 2016 that put water security and sustainability on the global agenda like never before:
Since 2011, that has changed. As shown in Figure 1, the proportion of people with access to a toilet has more than trebled – from under 20 percent to nearly 68 percent. Of 9,892 Gram Panchayats, the local level of government in India, almost a third – 3,545 – has been declared free of open defecation. That includes all Gram Panchayats in five of the state’s 33 districts, with more set to follow. What has gone right?
. Poor source water quality, non-existent or insufficient treatment, and defects in water distribution systems and storage mean these consumers use water that often doesn’t meet the WHO’s Guidelines for Drinking Water Quality.
The crowdsourcing framework develops a strategy to engage citizens in measuring and learning about the quality of their own drinking water. Through their participation, citizens provide utilities and water supply agencies with cost-effective water quality data in near-real time. Following a typical crowdsourcing model: consumers use their mobile phones to report water quality information to a central service. That service receives the information, then repackages and shares it via mobile phone messages, websites, dashboards, and social media. Individual citizens can thus be educated about their water quality, and water management agencies and other stakeholders can use the data to improve water management; it’s a win-win.
We cannot talk about water and Sustainable Development Goal (SDG) 6 without also looking at everything that depends on it: from climate, food and electricity to families, farms and ecosystems. It is thus quite simple, either.
Water and climate change are also intertwined, with some regions at risk of losing up to 6 percent of GDP by 2050 if the growing challenge of water scarcity is not properly addressed.
One of the biggest hurdles is the lack of sufficient sources of finance. Financing the SDG sub-targets for water supply and sanitation alone will cost triple historic financing levels - an estimated $114 billion per year between now and 2030. The shortfall for financing irrigation and water resource management sub-targets will likely be as large, if not larger.
