A recent study conducted by Zhu Yifan from the Key Laboratory of Groundwater Resources and Environment at Jilin University has shed light on the vulnerabilities of water resources in Changchun City, Jilin Province. This research, published in ‘Shuitu baochi tongbao’ (translated as “Water Conservation Bulletin”), employs a comprehensive evaluation system based on the DPSIR (Driving forces, Pressures, States, Impacts, Responses) model and the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method. It utilizes 19 indicators to assess the water resource situation over a span of 14 years, from 2005 to 2019.
The findings reveal that the water resource system in Changchun has experienced a transition from mild vulnerability in 2005 to a medium vulnerability level, fluctuating between 0.3 and 0.5 in subsequent years. Zhu emphasizes the complexity of the factors at play, stating, “The influence of each sub-system on the comprehensive evaluation results follows the order of pressure, impact, driving force, state, and response.” This hierarchy underscores the critical challenges facing water management in the region.
The study identifies total water use and total water resources as pivotal factors influencing vulnerability, with groundwater proving to have a more significant impact compared to surface water. This insight is particularly relevant for stakeholders in the water, sanitation, and drainage sector, as it highlights the need for a strategic focus on groundwater management. As Zhu notes, “The government should continue to increase investments in energy conservation and environmental protection,” suggesting that financial commitment is essential for sustainable water management practices.
For businesses operating within the water sector, these findings could signal a shift in market dynamics, emphasizing the importance of innovative water-saving technologies and enhanced treatment processes for urban water pollution. Companies that invest in these areas may find new opportunities for growth, especially in light of the increasing pressure on water supplies during dry years.
As Changchun continues to grapple with its water resource challenges, the implications of this research are profound. It not only provides a framework for assessing vulnerability but also serves as a call to action for policymakers and industry leaders to prioritize sustainable practices. By addressing these vulnerabilities, the region can work towards more resilient water management systems that benefit both the environment and the economy.
