Evaluating the potential impacts of land use changes on ecosystem service value under multiple scenarios in support of SDG reporting: A case study of the Wuhan urban agglomeration

Based on the data of land use in 1999, 2005, 2010 and 2020, selected the typical tourist area Yangshuo and research the land use changes on ecosystem service value and then estimated the value change. Throughout the study period, Yangshuo County has been always implement tourism development strategy, the unused land substantially reduced and transformed into woodland, water body and wetland, which makes the ecological environment has been improved. The total value of ecosystem services in Yangshuo County was 1067.4 million Yuan in 1999, 1165 million Yuan in 2005, 1478.3 million Yuan in 2010, from 1999 to 2020, the ecosystem service values increased 1002.9 million Yuan, it is mainly due to the increasing areas of woodland, water body and wetland. The combined ecosystem service value of woodland and cropland was about 90% of the total value. The contribution of each ecosystem function to the overall ESV was greatest for soil formation and retention, followed by water supply, both of them contributing about 34% of the total value. Yangshuo County implement eco-tourism, landscape of leisure tourism and agro-tourism as the development strategy, it provides a strong protection to protect the local environment, and promote the ecosystem service values on the rise.

Systematic studies on implications of land use change on ecosystem service value (ESV) at landscape level are scarce in Northeast India hence, a case study was undertaken in the vicinity of Ghagra Pahar Forest (GPF) predominated by tropical deciduous forest in Goalpara district of Assam. Study aims to assess the ecosystem services (ES) provided by the forest ecosystem. Altogether 23 ES were identified and grouped based on peoples’ knowledge and perceptions. Study area has been categorized in to six land use types. Temporal change analysis revealed that the area coverage under plantation, agriculture and settlement expanded, on the contrary, forest cover, water bodies and grassland decreased remarkably within a time gap of 20 years. The total ESV for the study area was disproportionately distributed among the different functions of ecosystem. Agricultural land contributed the maximum ESV. The total ESV declined at a rate of 0.64 percent per year with a net decrease of 12.7 percent. Sensitivity analysis shows that the values were less than unity indicating that total ecosystem service values would fluctuate only by 0.03-0.42 percent. Results of this study would be useful to the land use planners and policy makers to prioritise conservation efforts for sustainable resource management.
