About this event

IWRA webinar

Between mid-2021 and end of 2022, the IWRA Groundwater Task Force and the Groundwater Solutions Initiative for Policy and Practice (GRIPP) are organizing a series of webinars, each of which presents and reflects on different aspects of success when dealing with integrated groundwater solutions for water security, resilience and management. By reviewing, sharing and discussing examples of success, the visibility of options increase, supporting the Year of Groundwater – Making the Invisible Visible and the degree of transferability can be evaluated, while at the same time building global partnerships and communities of practice.

There is a growing number of large water transfer schemes around the world where aquifer storage and recovery become an important component. However, there are challenges, ranging from water allocation and pricing, balancing the amount of water for recharge and for regular or emergency use, water withdrawal and quality control, and financing for necessary infrastructure implementation and maintenance. 

The third Groundwater webinar will present three cases from different continents (Africa, Asia, and North America) to help understand the unique conditions and trajectories under which they developed as well as the institutional frameworks surrounding them.

Cases: 
  • China: Managed Aquifer Recharge through Rivers and Lakes in the North China Plains. Since 2018, large scale managed aquifer recharge has been conducted in the North China Plains to alleviate severe problems of groundwater over-exploitation. Water from the South-to-North Water Transfer Project, local reservoir storage, and reclaimed sources are utilized to recharge main rivers in over-exploited areas. Promising results, like water level rise, ecological flow increase, and ecosystem improvement, have been achieved.
     
  • USA: Mega Schemes on Interstate Water Transfer and Managed Aquifer Recharge in Southwestern USA. Arizona and Colorado and other states in the USA are increasingly collaborating toward ensuring water security and safety across many states from several sources, primarily the Colorado River. For more than a decade, innovative water banking schemes have been working in Arizona to enhance water capture and storage during times of surplus and recovery during times of need. With a long-term drought currently ongoing, which may represent a worst case scenario, the system will increasingly proof its value.
     
  • Africa: Underground Water Storage along the North-South Carrier in Botswana Saves Water Lost in Dams and Helps Strengthen Water Security for Expanding Economic Centers. Botswana is expanding on the implementation of managed aquifer recharge in strategic locations tying distant water surplus areas with high demand/deficit areas and securing year-round reliable supplies. Strategies for expanding accessory schemes in suburban areas are currently under development, benefitting about 50% of the population.
