The book series of the association has been widely disseminated in China, which has promoted the development of qroundwater science in China. IAH’s Strategic Overview Series (IAH-SOS) aims to inform professionals in a variety of sectors of key interactions with groundwater resources and hydrogeological science. Those titles are as followed: Ecosystem Conservation and Groundwater, Energy Generation and Groundwater, Food Security and Groundwater, Global Change and Groundwater, Human Health and Groundwater, Resilient Cities and Groundwater, UN-SDGs 2030 Essential Indicators for Groundwater, Mining Enterprises and Groundwater, Climate-change Adaptation and Groundwater.
