Saudi Arabia Innovates in Soil Quality and Water Conservation

Groundbreaking initiatives address desertification and sustainability challenges in the Kingdom.
Over the past decade, Saudi Arabia has made significant investments in sustainability, launching initiatives aimed at combating desertification, improving soil quality, and conserving water resources.

These projects align with the overarching objectives of the Saudi Green Initiative, aimed at enhancing the Kingdom's environmental landscape.

Among the most prominent efforts is the establishment of King Salman Park in Riyadh, which is set to become one of the world's largest urban parks.

This initiative emphasizes increasing green spaces, restoring soil health, and combating the urban heat island effect through native tree planting and the implementation of sustainable water management systems.

The project's long-term view focuses on delivering substantial environmental benefits.

Along the Kingdom’s east coast, Saudi Aramco has taken the lead in managing soil erosion, enhancing water retention, and fostering biodiversity.

This effort contributes significantly to addressing the environmental challenges faced in the region.

At the forefront of innovative soil solutions is the King Abdullah University of Science and Technology (KAUST), where advanced technology is being developed to tackle sustainability issues.

Himanshu Mishra, an associate professor at KAUST, has dedicated a decade to researching solutions for some of Saudi Arabia’s most pressing environmental challenges, particularly in water management and soil health.

Mishra has highlighted the complexities surrounding Saudi Arabia's water usage, noting that approximately 80 percent of the Kingdom's water is allocated for food production, despite the country importing a significant portion of its food supply.

This realization catalyzed his pursuit of sustainable solutions.

In response to the challenges of water conservation, Mishra co-founded SandX, a biodegradable, water-repellent sand coating designed to minimize water evaporation.

This technology imitates natural surfaces known for their water-repellent properties, including butterfly wings and bird feathers.

Each grain of SandX is treated with a nanoscale layer of biodegradable paraffin wax, which reportedly reduces water evaporation by over 80 percent without relying on plastics.

Mishra has emphasized the environmental significance of this innovation.

SandX degrades naturally, contributing to sustainability rather than detracting from it.

He notes that the traditional imports of peat moss for green spaces are costly and counterproductive, leading to the development of CarboSoil.

This advanced soil amendment and carbon capture technology, developed from organic waste, enhances soil fertility while simultaneously locking carbon into the ground, preventing it from being released back into the atmosphere.

Field trials for CarboSoil are currently underway, and production is anticipated to scale up following the receipt of a KAUST Innovation and Economic Development grant.

Mishra asserts that this technology will be instrumental in boosting food production and greening initiatives in arid zones.

In his outlook, Mishra envisions Saudi Arabia becoming a leader in carbon dioxide removal technology within the next five years, under the aegis of the Ministry of Environment, Water, and Agriculture.

The ambitions of SandX extend beyond the Kingdom, with plans to expand into the broader Middle Eastern region, focusing on the landscaping and agriculture sectors.

As the Kingdom progresses with these initiatives, the implications for environmental sustainability and agricultural productivity may reshape the landscape of water and soil management in Saudi Arabia.
