Emerging technologies can help tackling water insecurity
Blockchain technology can provide a secure, distributed and transparent ledger that can record the transaction between two parties. This will not only help in managing the water resource management, but it can also lead to check the water that is being traded.
As per the world, economic forum, there could be a fourth industrial revolution that can change the water and sanitation systems around the world. These five ways can help achieving the target of ending water security.
The first one is Blockchain technology, this can provide a secure, distributed and transparent ledger that can record the transaction between two parties. This will not only help in managing the water resource management, but it can also lead to check the water that is being traded.
With the help of this technology, the data availability becomes easily accessible and it could enable everyone including households, water managers, policy makers and industry consumers to access the data. The data would include quantity and quality of water. This would help customer making informed decisions, helping the conservation and better use of water.
The second way can be decentralized water reuse systems. According to the UN 2015 report on World Population Prospects, there would be 70 percent of the world population that would reside in the cities. A decentralized solution would be critical because, in a large urban area, the centralized systems would not be financially viable.
The president of the San Francisco-based NGO Imagine H2O, Scott Bryan says that water reuse, partly driven by the falling cost and improved efficiency of membrane bioreactor technology (MBR) over the past 10 years, can become common practice in a city's built environment and industrial zones.
The third one is managing water risk by getting basin level insights. There have been many activities from different organizations such as Dow, the Earth Genome, WWF, and others. These that could monitor the watershed health. Remote sensing, satellite imagery, remote sensing, IoT, AI and a lot of other advanced technologies can help in detecting the watershed level.
The fourth one is the use of advanced materials that can filter the saline water and make it drinkable. This can be done through a membrane system or with the use of advanced materials.
The fifth one could be a smart city of Water and sanitation system. The maintenance of water and sanitation systems can be monitored by the combination of IoT, AI, and other advanced technologies. The systems can help in basic design building as well as retrofitting of the cities to become more resilient. Such technological advancements can bring a lot of economic opportunities in the water and sanitation sector.
