A team of scientists has developed a plan to save the Dead Sea by bringing water from the Red Sea to address the water scarcity issue. The Red Sea-Dead Sea Project aims to stabilize the Dead Sea through a pipeline system, despite potential challenges related to its unique chemistry and environmental impact.
Insights
- The Dead Sea is facing a significant crisis with one-third of its surface lost due to water scarcity, prompting the Red Sea-Dead Sea Project to stabilize it by bringing water from the Red Sea, a complex endeavor with potential impacts on the sea's unique chemistry and appearance.
- The economic importance of the Dead Sea region is substantial, with potash mining and mineral extraction playing a significant role, but the decline of the Dead Sea has led to economic challenges affecting agriculture and tourism, highlighting the interconnectedness of environmental issues with local economies.

What is the Red Sea-Dead Sea Project?
The Red Sea-Dead Sea Project is a plan developed by scientists to save the Dead Sea by addressing the water scarcity issue in the Middle East. It involves stabilizing the Dead Sea by bringing water from the Red Sea through a pipeline from the Sea of Galilee to Jordan, desalination plants, and a massive pipeline to transport brine to the Dead Sea. The project aims to mix Red Sea brine with Dead Sea water, potentially forming gypsum crystals that could change the sea's color. However, the project faces challenges due to the unique chemistry of the Dead Sea and the uncertainty of its impact, requiring a gradual approach to monitor the effects of introducing Red Sea brine.
What causes sinkholes at the Dead Sea?
Sinkholes at the Dead Sea are caused by salt dissolution, a process that remains unpredictable despite years of study. The decline of the Dead Sea's water level due to water scarcity has led to the exposure of salt deposits in the ground. When freshwater flows underground and dissolves these salt deposits, cavities form, eventually causing the ground to collapse and create sinkholes. The formation of sinkholes poses a significant risk to infrastructure and human safety in the region, highlighting the environmental impact of the Dead Sea's water loss.
What is the National Water Carrier?
The National Water Carrier is a system constructed to divert water from the Sea of Galilee to cities on the Mediterranean coastline and the Negev desert. Over 96% of the water from the Jordan River into the Dead Sea has been diverted through this carrier, contributing to the man-made disaster of the Dead Sea's declining water levels. The diversion of water for agricultural and urban use has significantly impacted the Dead Sea's ecosystem, leading to environmental challenges and economic repercussions in the region.
How does the Dead Sea benefit tourism?
The Dead Sea's high salt content and rich mineral content, like magnesium, make it a popular tourist destination known for its healing properties. Tourists visit the Dead Sea to experience its therapeutic effects on skin diseases and enjoy floating effortlessly in its buoyant waters. The region's unique geological formation, linked to the Earth's crust rupture, creates a mineral-rich environment that attracts visitors seeking relaxation and wellness. Despite facing challenges from water scarcity and environmental changes, the Dead Sea remains a renowned destination for health and leisure tourism.
What is the impact of potash mining in the Dead Sea region?
Potash mining in the Dead Sea region is a major source of income for Jordan and Israel, contributing significantly to their economies. The Dead Sea Works in Israel, a prominent potash mining company, produces various products like magnesium chloride and table salts, employing thousands of people and generating billions in revenue. The extraction of minerals from the Dead Sea through potash mining plays a crucial role in supporting the local economies and sustaining livelihoods in the region. However, the mining activities also raise environmental concerns related to land degradation and water usage, highlighting the complex balance between economic development and environmental conservation in the Dead Sea area.

Dead Sea earthquakes, coral reefs, desalination concerns
- The region's earthquake history is well-documented, with evidence from the Dead Sea cliffs dating back to the last ice age around 12,000 years ago.
- The rock layers in the cliffs represent winter and summer deposits, with the darker layer formed during winter floods and the white layer composed of calcium carbonate from summer.
- Scientists have drilled 1,500 feet beneath the Dead Sea floor, revealing a 220,000-year record of earthquakes, including major ones like the Galilee earthquake in 1837 and the 1927 Jerusalem-Jericho earthquake.
- Concerns arise about the Red Sea-Dead Sea pipeline's vulnerability to earthquakes, given the region's seismic activity.
- The Gulf of Aqaba in the Red Sea houses pristine coral reefs untouched by bleaching, a phenomenon affecting corals globally due to climate change.
- Scientists predict the Gulf of Aqaba corals have about 100 years before bleaching occurs, attributing their resilience to warmer waters and unknown biological factors.
- The construction of a desalination plant in Aqaba raises concerns about the impact on marine life, particularly coral larvae crucial for reef renewal.
- A team of Israeli and Jordanian scientists proposes pumping water for desalination from below the photic layer to minimize harm to marine life, despite the higher costs involved.
