Soil Conservation Service Assessment

Climate change and human activities have changed the structure and function of global ecosystems and will continue to affect global ecosystem service provisioning. Soil conservation services are an important regulating service provided by ecosystems, referring to the erosion regulation capacity of ecosystems to prevent soil loss and the ability to retain sediment storage.

The sensitivity of soil erosion to global environmental change and its relevance to the socio-economic environment has made the development of adaptive management strategies to improve ecosystem soil conservation services and reduce soil erosion hazards a major concern of researchers.

Lifeasible's assessment of soil conservation services focuses on the supply of soil conservation services to natural systems (if you require a human benefits assessment for human systems, you can contact our staff to determine your assessment options). That is, the assessment is based primarily on a soil erosion perspective, which is a physical assessment of the ecosystem's impact on the erosion and sand production process.

Therefore, we commonly use InVEST (integrated valuation of ecosystem services and trade-offs) model, RUSLE (revised universal soil loss equation) model, NPP (net primary productivity) indicator model, Sediment Budget model, etc. for soil conservation services assessment and soil erosion assessment in the measurement of soil conservation services assessment.

Soil conservation service assessment methods

• Assessment index

• Measurement methods

Soil conservation service is a kind of "directional flow service", the erosion change in the upstream area will not only affect the local area but also affect other areas such as middle and lower reaches along with the water system or sediment transport path.

Therefore, Lifeasible's effective assessment of soil conservation services includes the full path of soil erosion, transport, and deposition as well as different spatial scales such as slope flow domain and regional global. The corresponding assessment indicators and methods can reflect the dominant processes and influencing factors at different scales, helping clients to obtain comprehensive and in-depth data information and profiles of soil conservation service changes.
