The Middle East and North Africa (MENA) region is home to just 6% of the world's population but less than 2% of its renewable freshwater resources. Climate change, population growth, and rapid urbanisation are intensifying the region's chronic water stress. By 2050, the World Bank projects that water scarcity could cost some MENA economies up to 14% of their GDP.
Yet alongside these challenges lies a wave of innovation. Governments, utilities, and companies across the region are turning ESG commitments into engines of water resilience—deploying cutting-edge desalination, water reuse, and technology-driven efficiency measures. What was once a looming existential threat is increasingly being reframed as a catalyst for transformation.
The Scale of the Challenge
Water scarcity in MENA is structural, not cyclical. Many countries already face "absolute scarcity" (<500 cubic metres per person annually). Groundwater resources are being depleted at unsustainable rates, while rising temperatures increase agricultural water demand.
The pressure is visible in multiple ways:
- Agriculture: Consumes up to 80% of freshwater in some countries, much of it via inefficient irrigation.
- Urban Growth: Cities from Cairo to Riyadh are straining ageing water infrastructure.
- Energy-Water Nexus: Power generation requires vast amounts of water—while water production through desalination requires huge amounts of energy.
This tight coupling of water, energy, and climate makes MENA uniquely vulnerable—and uniquely motivated to innovate.
Desalination: From Energy Hog to ESG Opportunity
MENA is already the global leader in desalination, producing more than 45% of the world's desalinated water. Historically, however, desalination has been energy-intensive and environmentally damaging, particularly through carbon emissions and brine discharge.
The region is now rewriting this story:
- Saudi Arabia: Through ACWA Power, the kingdom is pioneering renewable-powered desalination, including the world's largest solar desalination plant in Al Khafji.
- UAE: Abu Dhabi and Dubai are investing in hybrid renewable-desalination plants to cut emissions while scaling supply.
- Morocco: The Chtouka desalination project, powered partly by solar, will irrigate 15,000 hectares of farmland, combining food and water security.
By embedding desalination projects into broader ESG frameworks, countries are moving from emergency supply measures to sustainable, integrated strategies.
Wastewater Reuse: Closing the Loop
Water reuse is gaining momentum as a core ESG innovation. Treated wastewater is increasingly being repositioned from waste product to valuable resource:
- Israel: Though outside MENA proper, Israel sets a global benchmark, reusing nearly 90% of wastewater for agriculture.
- Oman: Investing in large-scale treatment facilities to support industrial water needs and urban greening.
- Egypt: The Bahr El-Baqar wastewater treatment plant, one of the largest globally, supports irrigation in Sinai while reducing Nile water pressure.
These investments demonstrate how circular water strategies align with both climate adaptation and ESG goals—reducing stress while creating economic value.
Technology and Data: Smart Water Management
AI, IoT, and advanced analytics are enabling water utilities to manage scarcity more intelligently:
- Leak Detection: Dubai's DEWA uses smart sensors to cut non-revenue water losses.
- Precision Agriculture: AI-powered platforms in Tunisia and Morocco help farmers optimise irrigation, increasing yields while reducing consumption.
- Satellite Monitoring: Regional partnerships use remote sensing to track groundwater depletion and crop water use.
These digital solutions are where ESG meets innovation—combining environmental stewardship with economic efficiency.
Policy and ESG Integration
Governments are embedding water into ESG frameworks:
- Saudi Arabia's Vision 2030 explicitly ties water sustainability to diversification goals.
- UAE's Net Zero 2050 strategy links water efficiency and reuse to climate adaptation.
- Regional Sovereign Wealth Funds (like ADQ and PIF) are investing in water technology as part of their sustainable finance portfolios.
Internationally, investors are pressuring companies operating in water-stressed regions to disclose risks and demonstrate resilience. The CDP's water questionnaire is increasingly seen as a baseline.
The Equity Dimension: Who Benefits?
Water innovation is not just about technology—it's about social equity. High-tech desalination and reuse projects risk bypassing rural or marginalised communities if access is not carefully designed. ESG-driven strategies must therefore prioritise:
- Affordability: Ensuring water prices remain accessible.
- Inclusivity: Extending modern water services to underserved rural populations.
- Transparency: Reporting not just on capacity built, but on who benefits.
Without this social dimension, water security risks reinforcing inequality rather than alleviating it.
The Path Forward: Scarcity as Catalyst
The MENA region is at the frontier of water innovation. What looks like constraint is driving creativity: solar desalination, circular reuse, AI-driven efficiency. But for these strategies to succeed, they must be embedded in robust ESG frameworks that balance environmental sustainability, social equity, and governance integrity.
Scarcity, paradoxically, is proving to be a powerful catalyst for innovation. If MENA can turn its most acute vulnerability into a model of resilience, the lessons will resonate far beyond its borders.
The question for leaders is not whether to act—scarcity makes that unavoidable—but how to ensure that water innovation delivers impact, equity, and long-term resilience.
