Global water crisis deepens as shortages spark conflicts and migration

Water scarcity is worsening across the globe, affecting billions of people and sparking rising tensions. Over two billion now live in countries facing extreme water stress, with agriculture consuming nearly 70% of freshwater supplies. Conflicts over water have surged since 2022, reaching over 400 incidents by 2024.

Droughts and mismanagement have pushed critical water sources to the brink. Iran’s Zayandeh Rud river dried up in recent years, triggering farmer protests in 2021 and 2022. Similarly, Lake Chad has shrunk by 90% since the 1960s, forcing migration as climate change and overuse deplete resources.

In conflict zones, water infrastructure becomes a target. The war in Ukraine left millions without drinking water after attacks on supply systems. Meanwhile, groundwater levels in northern India, the Middle East, and Central Asia have plummeted over the past two decades, according to NASA satellite data. Recurring droughts in Pakistan and Iraq have slashed agricultural output, leaving communities dependent on water tankers. Iran’s shortages have also caused severe land subsidence, with some regions sinking over 20 centimetres per year. Disputes over shared waterways, such as those between India and Pakistan under the Indus Waters Treaty, continue to strain diplomatic relations.

The combination of climate change, over-extraction, and geopolitical tensions is deepening the global water crisis. With groundwater reserves declining and key rivers disappearing, food production and rural livelihoods face growing threats. Governments and communities must now address both immediate shortages and long-term resource management.
