The Challenge:
Water Security in a Changing Climate

Climate change is disrupting global water systems, increasing the risk of scarcity, contamination, and extreme weather events.

By 2030, global demand for water may outstrip available supply by a significant margin, according to widely cited studies (United Nations Convention to Combat Desertification (UNCCD)). Figures vary by methodology and region, putting $300 billion in business value at risk and affecting families, communities, and businesses worldwide. With water stress intensifying, securing access to clean water is critical for health, economic stability, and environmental sustainability.

That’s why Allianz created this hub—to provide individuals, businesses, and communities with expert insights and practical solutions for navigating water security challenges. Whether you're looking to protect your family’s health, improve sustainability in your business, or understand water’s impact on well-being, we’re here to help.

of the world’s population will be living in water-stressed areas due to climate change and overuse by 2025.

of tap water samples exceed health safety limits for contaminants such as lead, nitrates, and bacteria, even in developed countries. (1)

increase in global water demand is expected by 2050, putting immense pressure on existing freshwater resources. (2)

deaths occur each year due to unsafe drinking water and waterborne diseases like cholera and dysentery. (3)

reduction in water usage can be achieved by businesses through simple conservation strategies, which lowers operational costs and promotes sustainability. (4)

of business water waste can be reduced with smart water meters and leak detection systems, improving efficiency and cutting costs. The extent varies by site and infrastructure (5)

1. Top water quality can vary by location, and some samples may exceed health safety limits. Ten European countries, including Austria, Finland, Greece, and Iceland, share the top EPI ranking for the cleanest water worldwide. - World Population Review

2. Forecasting future water demand reveals a wide range of potential outcomes. Projections suggest a 20% to 55% increase in global water use by 2050. - EFG International

3. Globally, 829 000 people are estimated to die each year from diarrhoea as a result of unsafe or inadequate drinking-water, sanitation and hygiene (WASH). - WHO

4. Businesses can reduce water consumption by conducting water audits, repairing leaks, installing water-efficient fixtures, reusing water where appropriate, and optimising irrigation systems. These measures can help improve water efficiency, reduce operating costs and conserve freshwater resources. - SAJDI

5. For example, Port Otago in New Zealand introduced electronic water meters to monitor water consumption and identify leaks more quickly. The meters provide usage data every 15 minutes and trigger alerts when consumption exceeds set thresholds, helping staff investigate unusual usage and resolve leaks sooner. - Arthur D Riley Co.
