Global Water Crisis and Climate Change
The Global Water Crisis and Climate Change – from Disaster to Opportunity
In the past year, and with the decline of the Corona virus, the world returned to focus on the most pressing existential threat – global warming and climate change, and their devastating effects on the world we live in. One of the main areas critically affected by climate change is the global rainfall cycle, resulting in less rain, more droughts and extreme rain events bringing with them more destruction than blessings. We believe that innovative technological solutions to the water crisis can be a central part of dealing with the climate crisis, for both adaptation and mitigation.
The close connection between the water crisis and the climate crisis was noted in the COP 27 summary statement and will be a central theme in the UN Water Conference that will open on the upcoming Water Day, March 22, at the UN headquarters in New York.
While many places in the world still have full access to clean tap water, in many other, this accessibility is limited and almost nonexistent.
It is estimated that some 2.5 billion people (36% of the world’s population) live in water-scarce areas, a phenomenon that is expected to worsen in coming decades as the powerful processes of climate change, global population growth, growing demand for industrial and agricultural products, and desertification will intensify. Water scarcity is causing migration, wars and conflicts, placing hundreds of millions of people around the world at risk of displacement due to water scarcity over the coming years.
To overcome this phenomenon and anticipate a cure for this ailment, we must understand that this will entail formulating a comprehensive campaign which will require that all necessary steps be integrated together, such as: Guide and educate on water conservation; increase water use efficiency; accrue international, public, and private funding; rehabilitate polluted water sources; encourage investments and R&D and first and foremost, to learn how to practice good water management in the local, national, regional and global scale.
We must explore new approaches towards investing in water and sanitation-related infrastructures and services, while ensuring each person’s right to safe drinking water. It is important that emphasis be placed on the availability and sharing of information about the amount, quality, distribution, and access to water, as well as of the risks and use of that water.
In this regard, Israel can make a significant contribution to the world as a country with one of the most advanced water systems in the world and with an abundance of R&D and innovative technologies in many fields. One example is the treatment and recycling of sewage: Israel holds a world record in this field, with 95 percent of its wastewater being treated from which almost 90 percent is used in agriculture.
Another field in which Israel holds a world record is the prevention of water loss in urban systems. While in Israel only a few percent of water is lost in urban supply systems, in other countries in the world, this rate can reach dozens of percent. The paradox is that these are often arid and water-scarce countries for whom the absence of available water represents a significant burden. In Israel, a comprehensive variety of technologies and methods have been developed to prevent water loss in supply systems, detect leaks through remote sensors, and more.
If this was the status quo the world over, it would be possible to greatly reduce and prevent environmental pollution and the destruction of natural systems, all the while allowing treated and purified water to flow back into nature and agriculture. It would be possible to simultaneously reduce large-scale emission of greenhouse gases, build agricultural resilience against climate chance, allow more water in nature for natural systems – which naturally absorb greenhouse gases – to better function, prevent unnecessary destruction of ecological systems as the result of pollution or water scarcity, and much more.
Seawater desalination, the use of brackish water in agriculture, drip irrigation, the development of agricultural varieties that consume less water, and even the extraction of water from air, are all fields that are developed in Israel. We in Israel are able and willing to share our accumulated knowhow and best practices with fellow nations around the world, so that together, we will assure that every individual across the globe will be able to enjoy the essential human right to safe and clean water.
Water is life.
