Introduction
In a world increasingly threatened by water scarcity, one small nation has managed to overcome seemingly insurmountable odds to achieve water abundance. Israel, a country with 60 percent of its land covered by desert, has not only solved its own water crisis but has become a global leader in water technology and conservation. Seth M. Siegel's book "Let There Be Water" explores how Israel achieved this remarkable feat and offers valuable lessons for countries facing similar challenges.
The Foundation of Water Mindfulness
A Culture of Water Appreciation
Israel's success in water management begins with a deeply ingrained cultural appreciation for water. Living in a desert environment, Israelis have long understood the precious nature of this resource. This mindfulness is reflected in various aspects of daily life:
Education: Schools teach students about water conservation from an early age, instilling habits that last a lifetime.
Religious traditions: Jewish prayers for rain, recited three times daily, have been part of the culture for centuries.
National symbols: Water-related imagery appears on currency and postage stamps, highlighting its importance to the nation.
This cultural foundation has created a population that naturally conserves water and supports innovative water policies.
Long-Term Planning for Self-Sufficiency
Recognizing the challenges posed by its geography, Israel embarked on a long-term plan for water self-sufficiency soon after its founding. The country faced a significant obstacle: its main water resources were located in the north, far from the populous central region and the arid Negev desert in the south.
To address this imbalance, Israel undertook a massive infrastructure project called the National Water Carrier. Completed in 1964, this system transported surplus water from the north to the central and southern regions, laying the groundwork for the country's water independence.
Technological Innovations
Drip Irrigation: A Game-Changing Discovery
One of Israel's most significant contributions to water conservation came from an accidental discovery. In the 1930s, water engineer Simcha Blass noticed that a tree near a leaking pipe grew much taller than its neighbors. This observation led to the development of drip irrigation, a technique that revolutionized agricultural water use worldwide.
Drip irrigation offers several advantages over traditional flood irrigation:
- It uses significantly less water.
- It doubles crop output.
- It frees up water for household use, improving overall living standards.
This innovation allowed Israel to maintain a thriving agricultural sector while reducing the proportion of water used for farming from over 70 percent to a more sustainable level.
Sewage Water Treatment and Reuse
Another area where Israeli scientists excelled was in the treatment and reuse of sewage water. While many countries still dump untreated sewage, Israel now reuses over 85 percent of its wastewater. This remarkable achievement is made possible through a process called sand aquifer treatment (SAT).
SAT systems use fine sand as a natural filter to clean wastewater effectively. This treated water can then be used for agriculture, supplying about one-third of the water needed for this sector. The implementation of SAT systems saves Israel more than one hundred billion gallons of water annually, significantly reducing the strain on freshwater sources.
Desalination: The Final Piece of the Puzzle
For decades, Israeli scientists sought a way to make seawater potable on a large scale. Early attempts, such as Alexander Yarchin's freezing method in the late 1940s, proved impractical and expensive. The breakthrough came in 1966 when Sidney Loeb, a Jewish-American chemical engineer working in Israel, developed the reverse osmosis technique.
Reverse osmosis works by pushing water through a membrane that separates pure water from salt molecules. This technology finally made large-scale desalination feasible, allowing Israel to tap into the vast resources of the Mediterranean Sea.
The impact of desalination on Israel's water security has been profound:
- It provides a climate-independent water source.
- It allows for the conservation of groundwater resources.
- It facilitates peaceful relations with neighboring countries through fair water distribution.
From Domestic Success to Global Export
Water Expertise as an Industry
Israel's success in solving its own water challenges has led to the development of a thriving water technology export industry. Israeli companies now offer a wide range of innovative solutions to countries around the world:
Bermad: This company created a device that precisely controls water flow, preventing waste. It now operates in 80 countries and employs 600 people.
Tahal: Specializing in water-technology solutions for developing nations, Tahal designs urban water supply systems and agricultural irrigation plans.
These are just two examples of the many Israeli companies that have turned water expertise into a lucrative export business.
Regional Cooperation and Assistance
Israel's water knowledge has also become a tool for regional cooperation and diplomacy. The country shares its expertise with neighboring Arab countries, including Jordan and the Palestinian National Authority. In Gaza, where water scarcity is a severe problem, Israel provides clean water, training, and technological assistance.
A notable example of regional cooperation is the joint project between Israel, Jordan, and the Palestinian National Authority to desalinate and redistribute Red Sea water among the three nations. This initiative demonstrates how water technology can serve as a bridge for peace and cooperation in a historically troubled region.
Water Diplomacy on the Global Stage
Building Bridges with China
Israel's water expertise has played a crucial role in its diplomatic relations, particularly with China. Despite historical tensions, the two nations began to build ties in the 1990s through water-related projects. When China faced water challenges in the mid-1980s, they invited Israeli water engineers to assist with irrigation plans for the Wuwei district near the Gobi desert.
This initial collaboration paved the way for broader diplomatic relations between the two countries, showcasing how water technology can open doors for international cooperation.
Assisting Developing Nations
Israel's commitment to sharing its water knowledge extends far beyond its immediate neighbors. Since the late 1950s, the country has been actively involved in sharing irrigation techniques with developing nations, particularly in Africa. Today, over 100 African countries benefit from Israeli training programs in water management and irrigation.
These initiatives not only help address water scarcity in developing regions but also foster goodwill and strengthen Israel's diplomatic ties around the world.
Collaborating with Developed Countries
Even wealthy, developed nations have sought Israel's expertise in addressing water-related challenges. For instance, Los Angeles, a city often plagued by drought, has turned to Israeli companies for help in tackling polluted groundwater sources.
This demonstrates that Israel's water solutions are applicable across a wide range of contexts, from arid developing regions to water-stressed areas in advanced economies.
Key Factors in Israel's Water Success
Public Ownership of Water Resources
A cornerstone of Israel's water management strategy is the public ownership of water resources. The Israel Water Law of 1959 established that water should be managed centrally by government agencies rather than private corporations. This approach allows for:
- Accurate assessment of available resources
- Comprehensive planning for the country's water needs
- Equitable distribution of water resources
By treating water as a public good, Israel ensures that this vital resource is managed in the best interest of the entire population.
Real-Cost Pricing
Unlike many countries that heavily subsidize water, Israel implements a real-cost pricing model. This means that consumers pay the full cost of the water they use, without government subsidies. While this may seem counterintuitive, it offers several benefits:
- It encourages conservation by making users aware of the true value of water.
- It provides funds for maintaining and improving water infrastructure.
- It incentivizes the development of water-saving technologies.
This pricing strategy has been crucial in promoting responsible water use and funding ongoing innovations in the water sector.
Government Support for Innovation
The Israeli government has played a vital role in fostering innovation in the water technology sector. Key initiatives include:
- Financial incentives for new water ventures
- Support for water-innovation start-ups
- Encouragement for municipal water utilities to test and implement new technologies
This proactive approach has resulted in the launch of over 200 water-innovation start-ups in the past decade alone, cementing Israel's position as a global leader in water technology.
