Iraq, the historic "land between two rivers," faces a crisis striking at its identity as the Tigris and Euphrates shrink dramatically amid severe drought and the increasing toll of upstream dams, helping create the country's worst water shortages for decades.
Once symbols of abundance, the two rivers, which both originate in Turkey, have become the focus of a struggle forcing Iraq to use its most lucrative asset – oil – to secure its water.
The country of more than 46 million people, is experiencing a sharp decline in water supply due to a tangle of factors, including the construction of upstream dams in Turkey, Iran and Syria; broken and outdated water infrastructure after decades of war, sanctions and instability; and government mismanagement.
Adding pressure is a severe, climate change-fueled drought, Iraq's worst in nearly a century.
At the same time, demand is increasing due to growing urban populations and a thirsty agricultural sector, which consumes more than 80% of Iraq's water resources.
Heavy rain and flash floods hit Iraq for several days this month, killing at least six people, according to the state-run Iraqi News Agency. However, Iraq's dams still face a large water shortage after years of low rainfall, the country's water resources ministry said in a statement.

The built environment is undergoing a structural transformation driven by regulation, resilience and resource efficiency in construction. The UK’s post-Grenfell regulatory regime has intensified accountability across the sector, demanding transparent dutyholder responsibility and measurable performance in sustainable construction. The government’s plan to reform water governance, alongside stricter rules on leakage and pollution, elevates the importance of sustainable building design that prioritises water efficiency, life cycle cost and whole life carbon assessment. Developers face rising expectations to integrate eco-design for buildings that reduce run-off and demand rather than relying on infrastructure resilience alone.
Climate adaptation is now overt reality, with managed retreat shaping policy and finance. The demolition of coastal homes in Thorpeness demonstrates how location risk is being priced into valuations and insurance. This shift underscores the necessity of sustainable urban development based on lifecycle assessment, whole life carbon reduction and low carbon design to mitigate the environmental impact of construction. The resilience transition highlights that net zero whole life carbon and circular economy principles are not theoretical ambitions but essential for long-term asset viability.
Innovation on the supply side is reinforcing circular economy in construction. The University of Birmingham’s new rare-earth magnet recycling plant supports a circular supply chain for renewable building materials essential to low carbon building systems, from heat pumps to vertical transport. Yet progress on decarbonising materials such as cement and steel remains uneven, showing that embodied carbon in materials and process transparency must go beyond artificial intelligence and data analytics to achieve meaningful carbon footprint reduction. Cleaner production depends on applying life cycle thinking in construction and adopting low embodied carbon materials supported by environmental product declarations (EPDs).
Investment in flexible energy infrastructure, including platforms enabling energy-efficient buildings to interact with the grid, signals a future of decentralised, renewable power and carbon neutral construction. Policy signals remain inconsistent, but the imperative for environmental sustainability in construction is clear. Build fabric-first, electrify systems, embed circular construction strategies and specify green building materials validated through whole life carbon reporting. Those priorities define sustainable material specification, improve building lifecycle performance and align with BREEAM and BREEAM v7 standards, strengthening the economic case for decarbonising the built environment.
