Nature-based solutions to China’s development challenges
Overview
While China’s remarkable industrial development has lifted hundreds of millions out of poverty and created a large middle class, it has also caused significant biodiversity loss, ecosystem degradation, and pollution in urban and rural areas. These environmental crises threaten human health and safety and undermine long-term economic development.
In response, China’s government is now promoting a system of ecological civilization to align environmental conservation and socio-economic development through initiatives in natural capital investment, sustainable infrastructure, biodiversity protection and renewable energy. Notably, China has committed to establishing official protection over 30% of its land by 2030 and achieving carbon neutrality by 2060.
SCCEI is collaborating with the Stanford Natural Capital Project (NatCap) and the Chinese Academy of Sciences’ Research Center for Eco-Environmental Sciences (RCEES) to advance nature-based policy solutions and support sustainable development in China and around the world. Our research focuses on four key areas: Ecological Civilization, Gross Ecosystem Product, Urban Nature and Health, and Nature and Rural Vitalization.

Ecological Civilization
Ecological Civilization, a new policy system in China, is designed to align environmental conservation with socio-economic development. Our research analyzes this emerging policy framework and identifies opportunities for collaboration with government, enterprises, and civil society.
Gross Ecosystem Product
Gross Ecosystem Product (GEP) is an index that aggregates the total value of ecosystem goods and services into a single monetary metric. Co-developed by NatCap and RCEES, GEP is now being piloted in China on local and national levels.
Urban Nature and Health
With over 1 billion people projected to live in China’s cities by 2030, the mental and physical health of the urban population has become a top priority. Our research identifies how nature solutions can improve public health outcomes, with a focus on the role of urban greenspace.
Nature and Rural Vitalization
China’s rural countryside faces increasing needs for both environmental and economic investment. Our research aims to coordinate investments in natural capital with investments in human capital to transform China’s countryside into a frontier of sustainable development.
Significance
Following severe environmental degradation from rapid economic development, China is now advancing policies to secure biodiversity and ecosystem services. We report the first nationwide assessment, showing that protected areas (PAs) are not well delineated to protect either biodiversity or key ecosystem services. This serious deficiency exists in many countries. We propose creating a national park system in China to help guide development along a path of green growth, improving the well-being of both people and nature. This involves establishing new, strictly protected PAs for biodiversity and ecosystem services that are highly sensitive to human impacts, as well as a new PA category—in China and ideally worldwide—for integrating biodiversity, ecosystem services, and human activities to achieve sustainable development goals.
Abstract
Recent expansion of the scale of human activities poses severe threats to Earth’s life-support systems. Increasingly, protected areas (PAs) are expected to serve dual goals: protect biodiversity and secure ecosystem services. We report a nationwide assessment for China, quantifying the provision of threatened species habitat and four key regulating services—water retention, soil retention, sandstorm prevention, and carbon sequestration—in nature reserves (the primary category of PAs in China). We find that China’s nature reserves serve moderately well for mammals and birds, but not for other major taxa, nor for these key regulating ecosystem services. China’s nature reserves encompass 15.1% of the country’s land surface. They capture 17.9% and 16.4% of the entire habitat area for threatened mammals and birds, but only 13.1% for plants, 10.0% for amphibians, and 8.5% for reptiles. Nature reserves encompass only 10.2–12.5% of the source areas for the four key regulating services. They are concentrated in western China, whereas much threatened species’ habitat and regulating service source areas occur in eastern provinces. Our analysis illuminates a strategy for greatly strengthening PAs, through creating the first comprehensive national park system of China. This would encompass both nature reserves, in which human activities are highly restricted, and a new category of PAs for ecosystem services, in which human activities not impacting key services are permitted. This could close the gap in a politically feasible way. We also propose a new category of PAs globally, for sustaining the provision of ecosystems services and achieving sustainable development goals.
China recently completed its first National Ecosystem Assessment covering the period 2000–2010. Ouyang et al. present the main findings of the assessment. Investment in the restoration and preservation of natural capital has resulted in improvements at the national level in most of the major ecosystem services measured. In particular, food production, carbon sequestration, and soil retention showed strong gains; on the other hand, habitat provision for biodiversity showed a gradual decline. Regional differences remain nonetheless, and there are serious environmental challenges still to be met in areas such as air quality and the wider global footprint of raw material imports.
China makes a unique and vital contribution to maintaining global and regional waterbird diversity and conservation. Despite considerable historical conservation efforts, the continued loss of waterbird diversity and abundance necessitates a contemporary review of Chinese sites of conservation significance. The Ecological Protection Red Line (EPRL) was proposed by China’s Central Government in 2013 to protect areas providing crucial ecosystem services and provides the opportunity for such a review to enhance waterbird conservation in China. By incorporating various sources of data, surveys and information, we identified a suite of sites of waterbird conservation significance in China, following the Ramsar Site Criteria/Important Bird and Biodiversity Area (IBA) Criteria. In total, we identified 422 sites, of which the existing 286 IBA sites formed the basis of the site safeguard network. Altogether, these sites of waterbird conservation significance constitute over 727,000 km2 (7.6% of China’s land surface). Over half of the area of these sites is outside China’s national nature reserves, thus confirming the importance and urgency of including them in the EPRL for the effective conservation of waterbird sites. We suggest that this assessment of sites of waterbird importance offers a useful model to apply to other taxa, such as terrestrial birds and mammals.
