“…Our weight approach was similar to other authors. In particular, Veldkamp and Fresco () defined the relative values of different LCs in the 0–7 range for four predefined strategies for assessing land conversion, whereas Gashaw et al () set the ecosystem service coefficient to be equal (in USD·ha −1 ·year −1 ): 0 for built‐up areas, 225 for cultivated land, and 987 for forest, in line with the ascending weight order that we adopted ( w artificial < w agricultural < w forested ).…”

“…The spatial characteristics of LCTs vary between the catchments, It seems that the proposed methods of LCT (LCT and LCT d ) can be easily used to analyze and visualize spatial land development or its degradation. Apparently, a similar analysis can be applied to other domains, including environmental, socioeconomic, or ESVs (Costanza et al, 2014;Gashaw et al, 2018;Sutton et al, 2016), because it only requires defining spatial features and adopting the appropriate range of weights. Our weight approach was similar to other authors.…”

In the PC, between 1990 and 2012, the main changes concerning the conversion of agricultural land to built-up or forested land took place mainly at the height of 200-400 m a.s.l.…”

Widespread, human‐induced land cover (LC) transitions in areas surrounding national parks and nature reserves, accompanied by changing climate conditions, can trigger serious consequences for these natural environments and their ecosystems. The aim of the study was to assess the direction and magnitude of transitions in LC in the Polish Carpathians since 1990 for determining the current status of land degradation neutrality and future degradation risk as well as to analyze concomitant changes in climate conditions to enable sustainable land management. The study area encompasses six national parks with the United Nations Educational, Scientific, and Cultural Organization biosphere reserves, several dozen nature reserves, and landscape parks and is a key source of drinking water in Poland. We studied detailed changes in LC (13 classes). The Wilcoxon signed rank test indicated significant increases in built‐up areas (urban fabric and industrial/transport infrastructure), waters, dense forest cover, and herbaceous vegetation but a decrease in heterogeneous agricultural areas. On the basis of two new methods, we assessed the LC transitions for 20 mountain catchments and for the entire Polish Carpathians. Although we found a slight positive transition in LC for the entire Polish Carpathians, clearly negative transitions occurred in the five analyzed catchments, including those covering two national parks. These LC transitions are accompanied by changing climate conditions with significant increases in air temperature and precipitation. The ongoing intensive urbanization in the studied mountain region, which is accompanied by significant regional warming, implies the need to apply sustainable management practices that will avoid or reduce degradation in the catchments involved.

“…For example, Kindu et al [21] reported the loss of ESS in Munessa-Shashemene landscape of the Ethiopian highlands valued between 19.3 million USD to 45.9 million USD in the four decades between 1973 and 2012. Gashaw et al [38] also reported the reduction of the value of ESS in Andassa watershed in the Upper Blue Nile basin from 26.83 million USD in 1985 to 22.58 million USD in 2000, due to LULC change. Similarly, Tolessa et al [39] reported a loss of the value of ESS in the central highlands of Ethiopia from 1973 to 2015, mainly due to forest cover change in the area.…”

“…Despite a significant number of studies on LULC change and driving forces in Ethiopia, efforts to quantitatively assess the impact of LULC change on a wide range of ESS are seldom attempted in the country. A few recent studies, by Kindu et al [21], Tolessa et al [39,46], and Gashaw [38], are mainly concentrated in the central highlands of the country.…”

This study evaluated the effect of Land Use and Land Cover (LULC) dynamics on the value of ecosystem services in Abaya-Chamo basin over 1985-2050. The main objectives of the study were to estimate the value of ecosystem services of Abaya-Chamo basin using local and global ecosystem service value coefficients, assess how it changes over time, and develop tools to inform policy and public decision-making to protect lands and waters in the region. The study utilized observed (1985 and 2010) and predicted (2030 and 2050) LULC datasets and ecosystem service value coefficients obtained from publications in peer-reviewed scientific journals. The results indicated that the total ecosystem service value of Abaya-Chamo basin was 12.13 billion USD in 1985 and 12.45 billion USD in 2010. The value is predicted to increase to 12.47 billion USD by the year 2050, which is 2.84% (344.5 million USD) higher than the total value of ecosystem services of the basin in 1985. Although the total ecosystem service value of the basin showed a slight increase over the study period, it was observed that the total value of services obtained from natural ecosystems is expected to decline by 36.24% between 1985 and 2050. The losses of services obtained from natural ecosystems, such as water regulation and erosion control, are major concern as the consequence has already been reported in the basin in the form of reduced water quality and productivity of the lakes due to an increased soil erosion and sediment transport in the basin. Therefore, special attention should be given to the rehabilitation of degraded ecosystems and the protection of remaining natural vegetation and water bodies to enhance natural capital and ecosystem services in the basin. A large-scale dissemination of eco-agricultural land use practices, which provide multiple ecosystem services (such as agroforestry and heterogeneous agricultural areas) in the basin, needs to be considered in the future.

The economic value of grassland ecosystem services: A global meta‐analysis

et al. 2022

View full text Add to dashboard Cite

Background: Grasslands provide a wide variety of ecosystem services that contribute to human wellbeing. While an increasing number of studies are evaluating the monetary value of grassland ecosystem services, most of them focus on specific grassland ecosystem services at regional or local scales, and they use different assessment methods. Methods: This paper provides a comprehensive assessment of the economic value of global grassland ecosystem services based on a meta-analysis of 702 observations from 134 primary studies. Results:The economic values of different ecosystem services cover a wide range of grassland types, regions, and estimation methods. The annual economic value per hectare ranges from $3955 for semidesert grasslands to $5466 for tropical grasslands. On average, regulating services have the highest value, which is approximately four times that of provisioning services or approximately eight times that of food supply services. Several factors impact the estimated ecosystem service values, including the evaluation method, source and year of publication, and study site. The results indicate that the annual economic value of global grasslands exceeds $20.8 trillion. Conclusions:The findings of this study not only provide useful information for understanding the economic value of various ecosystem services associated with different types of grasslands but also have important policy implications for the ecological conservation of grassland globally.
