Water Security and Technological Innovation in China

Abstract: Water security is emerging as a critical issue for China because of various key factors, such as the unequal distribution of water resources and climate variability. As a consequence, China presents important structural imbalances between the humid South and the arid North, also causing groundwater depletion, subsidence and drought. These vulnerabilities need the integration of scientific observation and technological innovation in order to build sustainable and resilient water management frameworks. This study combines hydrological monitoring and advanced modelling to examine some crucial contexts in several Chinese regions and the water reuse strategies. By analysing data and new technologies, the paper aims to represent a scientific foundation for China’s transition in the direction of climate-resilient governance and sustainability. Unlike most studies that focus on isolated hydrological or infrastructural components, this analysis proposes an integrated, machine-learning based framework that links hydrological, climatic and socioeconomic data to support climate-resilient water governance in China.
