Key Findings
- 01Inadequate water quality exacerbates China's freshwater scarcity.
- 02Water scarcity is unevenly distributed, with North China facing year-round scarcity and South China experiencing seasonal scarcity due to quality issues.
- 03Over half of China's population is affected by water scarcity.
Application
Design takeaway
When designing systems or products that rely on water, always assess both the quantity and quality of available water resources, as pollution can render seemingly abundant water unusable.
How to apply
When developing new products or infrastructure in water-stressed regions, conduct a thorough assessment of local water quality alongside quantity to ensure long-term viability and usability.
Project actions
- 01When researching a problem, consider all factors that make a resource unusable, not just its availability.
- 02Think about how environmental factors like pollution can create inequalities.

Variables
Strengths & Limitations
Strengths
- +Comprehensive nationwide assessment.
- +Integration of water quality as a key factor.
Limitations
The specific pollution types and their impacts can vary greatly by location, so general findings need local validation.
Reliability & validity
The study's validity relies on the accuracy of its water quality data and the appropriateness of the chosen water quality thresholds for human uses. Reliability would depend on the consistency of data collection and modeling methods.
Think critically
How might the specific types of pollutants in a region influence the design of water treatment or usage systems?
Design Principles
"Usable water availability is a function of both quantity and quality."
This research highlights that simply measuring water quantity is insufficient for understanding true water scarcity. Designers and engineers must consider water quality as a critical factor in resource management, especially in regions facing pollution challenges, to ensure water is truly usable for intended purposes.
What This Means for Your Design
Just because there's a lot of water doesn't mean it's clean enough to use. Pollution makes water scarcity worse and affects people differently depending on where they live.
How to use in your project
- 1.Use this research to justify the importance of considering water quality in your design project's context, especially if your project involves water usage or management.
