Abstract:

Increasing land development throughout China poses serious risks to environmental services including water supplies, freshwater and terrestrial habitats, and soil erosion. Resource management must increasingly anticipate effects of resource use including the design of mitigation strategies. Because of the vast areas involved, detailed environmental assessments and resource management planning that require extensive data collection, analysis and modeling may not be suitable or cost effective in many instances. Yet, developing and communicating environmental information more broadly, in a spatial context, is necessary to support sustainable land uses and watershed management in China into the future. A ‘digital watershed’ provides a spatial framework, in which landforms and physical processes are analysed in context with patterns of resource use and human infrastructure. Analyses using digital watersheds can increase the site specificity and defensibility of resource planning at watershed to regional scales by government agencies and the private sector, while concurrently restraining costs of environmental assessments. The digital watershed represents a significant advancement over existing digital representations of land and streams in China. Here, we describe NetMap’s digital watershed and analysis tools, illustrating their use in China.
