Assessing and Forecasting Resource and Environmental Carrying Capacity: A Case Study of Henan Province

The Fragile Balance: Understanding Resource and Environmental Carrying Capacity

The delicate interplay between resources, the environment, and human activities defines a region's Resource and Environmental Carrying Capacity (RECC). It represents the limit to which a region can support societal and economic progress without jeopardizing the environment's long-term health.

Since the 20th century, rapid technological advancements have spurred both social progress and a concerning disconnect between resource consumption and sustainable practices. This has led to resource depletion, pollution, and escalating conflicts between economic growth and a healthy environment.

A Deep Dive into Henan Province's RECC

This study examines the RECC of Henan Province, a vital agricultural region in China, using a novel evaluation system that incorporates PM2.5 indicators, reflecting the interconnectedness of soil and air quality. From 2014 to 2023, Henan's RECC experienced an overall decline, punctuated by periods of fluctuation, hitting its lowest point in 2019 before showing signs of gradual recovery. This underscores the complex and dynamic nature of RECC, influenced by various interacting factors.

Delving deeper, the analysis reveals a concerning decline in natural carrying capacity, dwindling from moderate to relatively weak. This is attributed to pressures on land resources from urban expansion, over-exploitation of water resources, and unsustainable mineral extraction. Environmental carrying capacity also exhibited a concerning, albeit less dramatic, downward trend due to challenges related to air and water quality, soil health, and ecosystem stability.

On a more positive note, Henan's socio-economic carrying capacity experienced an upward trajectory, improving from moderate to relatively strong. This highlights the province's economic progress, but also emphasizes the persistent tension between economic growth and the strain on resources and the environment.

Early Warning Management: Charting a Sustainable Course

The study's findings highlight the urgent need for proactive management strategies to safeguard Henan's RECC. These include implementing stringent regional restrictions based on overloading factors, legally suspending unsustainable projects, and enacting penalties for environmental damage. Reward mechanisms for positive changes are also proposed to incentivize sustainable practices.

Targeted measures are crucial. Water resource management should focus on stricter water-saving standards and optimizing industrial structures. Land resource management needs to prioritize farmland preservation and promote efficient land use. Ecological management should focus on ecosystem restoration and promoting a green economy.

Crucially, the establishment of a comprehensive monitoring and warning database, leveraging information technology, is essential for real-time data sharing and dynamic updates. This will enable timely interventions and informed decision-making.

Looking Ahead: Refining RECC Assessment

This research employs the Analytic Hierarchy Process (AHP) to evaluate RECC. While AHP offers valuable insights, its inherent reliance on expert judgment can introduce subjectivity. Future research should explore incorporating more objective data sources and advanced modeling techniques, particularly in light of the complex, cross-scale interactions across different regions in China.

Key Takeaways: Lessons for Sustainable Development

This study provides a detailed assessment of Henan Province's RECC, offering a unique perspective by integrating PM2.5 into the evaluation framework. The findings not only shed light on Henan's specific challenges but also provide valuable lessons for similar regions grappling with sustainable development. The study emphasizes the need for integrated approaches that balance economic growth with the responsible management of natural resources and the environment.
