Due to climate change, population growth, increasing urbanization etc., many lakes, rivers, wetlands and coastal basins globally are becoming more stressed from pollution, depleting water resources, global warming, increased floods and droughts, and increasing ecological and biological disruptions. Whilst practicing water scientists, engineers and managers in regulatory authorities, water companies, consulting and contracting companies, private and public investment bodies and non-governmental organizations are focused on trying to manage water security, there is a growing need to improve water management through more and smarter use of data and nature-based solutions.

To focus on valuing water and framing high-level adaptive, real-time monitoring and nature-based solutions to the challenges and opportunities of global water security, the International Association for Hydro-Environment Engineering and Research (IAHR) is organizing the 3rd Webinar on Global Water Security on March 22, 2021 with an emphasis on the fundamental issues of global water security: linking water security to nature, and on managing and improving the resources and quality of water in lakes, rivers, wetlands and coastal based systems
