“…Due to LULC changes and urbanization, most of these studies showed moderate to significant decrease in ESV [15,16,28,29,41,43] while others found almost no change [46]. Some studies have also revealed an increase in ESV [47][48][49][50]. Such variations in the services value are of the following reasons.…”

Impact of land use land cover changes on ecosystem service value – A case study of Guangdong, Hong Kong, and Macao in South China

The rapid increase in anthropogenic activities, socioeconomic development, and land use land cover (LULC) changes since the opening of economic reforms (1978), have changed the ecosystem service value (ESV) in Guangdong, Hong Kong, and Macao (GKHM) region located in South China. This leads to the requirement of a significant tailored analysis of ecosystem services regarding incisive and relevant planning to ensure sustainability at regional level. This study focuses on the use of Landsat satellite imagery to quantify the precise impact of LULC changes on the ecosystem services in GHKM over the past three decades . The most renowned established unit value transfer method has been employed to calculate the ESV. The results show that the total ecosystem service value in GHKM has decreased from 680.23 billion CNY in 1986 to 668.45 billion CNY in 2017, mainly due to the decrease in farmland and fishponds. This overall decrease concealed the more dynamic and complex nature of the individual ESV. The most significant decrease took place in the values of water supply (-22.20 billion CNY, -14.72%), waste treatment (-20.77 billion CNY, −14.63%), and food production (-7.96 billion CNY, −33.18%). On the other hand, the value of fertile soil formation and retention (6.28 billion CNY, +7.26%) and recreation and culture (5.09 billion CNY, +12.91%) increased. Furthermore, total ESV and ESV per capita decreased significantly with the continuous increase in total gross domestic product (GDP) and GDP per capita. A substantial negative correlation exists between farmland ESV and GDP indicating human encroachment into a natural and semi natural ecosystems. The results suggest that in the rapidly urbanizing region, the protection of farmland and to control the intrusion of urban areas has marked an important societal demand and a challenge to the local government. This required a pressing need for smart LULC planning and to improve policies and regulation to guarantee ecosystem service sustainability for acceptable life quality in the study area and other fast expanding urban areas in China.

“…As such, most of the mixed vegetation around the forests were abandoned while they reforest. Wang et al [45] also observed the cushioning impact of increased forest cover on the total ESV of Ningxia of China. Moreover, the forest becoming patchy due to fragmentation and the influx of other land use types into the forest areas caused deforestation and decreased the overall services the landscape provided in 2016.…”

Ghana's economic development relies largely on the mining industry, but the ecological cost is very high, particularly for the small-scale sector. To ascertain and give an account of the ecological pressures from the small-scale gold mining sector, we quantified and appraised the ecosystems (land cover types) degradation due to mining land use along portions of the renowned Pra River basin of Ghana. The study classified and analysed high-quality Landsat image data to monitor processes and changes in the river basin and adopted the Ecosystem Service Value (ESV) model to quantify the forgone value in monetary term. The results revealed that the initial ESV of 17.69 million US$ in 1986 increased to 18.40 million US$ in 2002 for the study landscape with the small-scale mining sector accounting for 8.4% of the trade-off costs. The expansion of forest areas and its higher value coefficient (VC) was, however, prevalent and this resulted in a net positive change during this period. However, in 2016, out of the total ESV of 14.63 million US$ obtained, the small-scale mining activities accounted for 36.8% of the trade-off costs. The substantial increase in trade-off costs with a subsequent decrease in ESV in the study landscape, following the intensification of small-scale gold mining, indicates that their activities have been degrading the watershed ecosystem and are, therefore, unsustainable. The study affirms the need for policymakers/government to review the laws, particularly on post-mining monitoring schemes to deter illegal miners and support the registered small-scale miners who are willing to implement land rehabilitation activities.

“…In this approach, the natural ecosystem is proposed to represent one seventh of the actual food production. From 2006 to 2015, the average actual grain production in Dinghai district was 4826 kg/ ha, and the average price for grain (mainly composed of paddy, wheat, maize) was 2.1 Chinese yuan/kg (1 Chinese yuan = $0.16 USD) (Wang et al 2014). One equivalent factor of the ESV is therefore 1447.8 Chinese yuan (1.0*4826*2.1/7).…”

Recently designated as a new special economic zone in China, Zhoushan Archipelago is going through a rapid land use change that is expected to have significant impacts on ecosystem services. However, there is no baseline of ecosystem service value (ESV) of the Zhoushan Archipelago up to date, making it impossible to assess any impacts of land use changes. In this study, we adopted the concept of "equivalent value per unit area of ecosystem services in China" and computed the ESV for 2006, 2012, and 2020 of a representative district, Dinghai, on the Zhoushan Archipelago. We then analyzed the spatial and temporal patterns of land use changes and their impacts on ESV. The results indicated that the ESV of Dinghai District declined by 59.3 M Chinese yuan ($9.5 M US dollars) from 2006 to 2012 and would further decrease by an additional 30.9 M yuan ($5 M US dollars) by 2020 according to its planned land uses. These declines in ESV were primarily due to increases in buildup areas and losses in wetland, farmland, and water areas. The results imply that more attention should be paid to controlling urban growth and protecting coastal wetlands in order to preserve valuable ecosystem services of the Archipelago.
