Filling the Water Storage Gap: Advancing a resilient and sustainable agenda to ensure a water and food secure future in the face of climate change
12:30 pm > 01:45 pm UTC-04:00
UN 2023 Water Conference
Thursday March 23 | 12:30–1:45 PM | Nature Hub – Apella – 450 E 29th Street
This unofficial side event at the UN 2023 Water Conference will highlight the critical need to develop and scale a new, integrated agenda for water storage and management – one that includes nature-based solutions – to achieve shared goals of water security for people and planet.
While water storage and management are essential to societies, economies and ecosystems, there is a large and growing gap in water storage in many places around the world, exacerbated by increasing climate variability and extreme events such as floods and drought. Current approaches to filling the water storage gap have relied heavily on built infrastructure, primarily dams, which have too often resulted in high and unacceptable social and environmental costs and unintended socio-environmental consequences. Instead, addressing this gap must consider the continuum of water storage options available for different contexts. Natural water assets, or nature-based solutions, are receiving increased attention as potential solutions for climate and nature. Such assets, like wetlands and recharge of aquifers, have always played a key environmental role throughout millennia in achieving water security and storage. At the same time, investment and integration of robust and replicable nature-based approaches into human-designed water storage solutions have been lacking.
A global dialogue around sustainable and integrated approaches for closing the water storage gap is therefore urgently needed to develop concrete frameworks, approaches and solutions to address these dynamic and pressing challenges. This session will provide an overview of the growing demand for water resources and storage (especially for agriculture and irrigation), the challenges and opportunities to meet these demands, and the importance of taking an integrated approach to water storage and management. It will examine a number of country case study examples and engage with a wide range of stakeholder perspectives.
