“…These impacts have created many ecological problems (e.g., soil erosion, sandstorms, flooding) [26]. The main goals of regional ecosystem management are to identify the ecological risks of ecosystem services and their drivers and maintain the sustainable delivery of ecosystem services through effective warning systems of ecological risk [3,4]. A framework for ecological risk assessment was constructed using the ecosystem services approach in this study.…”

“…Furthermore, it is projected that ecosystem services will face greater degradation risks over the first half of this century due to land-use change, invasive species, over-exploitation, pollution, and climate changes [2]. One of the greatest challenges is assessing and understanding the ecological risks of ecosystem services [3] in order to determine a viable way in which to manage human interactions with ecosystems and maintain the sustainable supply of ecosystem services [4].…”

Worldwide, most ecosystem services have declined. However, the theoretical and analytical frameworks for the ecological risk assessment of ecosystem services are still lacking. Here a framework for the risk assessment of ecosystem services was developed based on the formation, changes, risk, and management of ecosystem services. The framework was tested in Ganzi, the upstream area of the Yangtze River Basin, for the regional ecological warning of ecosystem services. Ecosystem services in the form of soil retention and sandstorm prevention and ecological risks including soil and wind erosion were modelled. The results showed that with the increase in area and quality of natural vegetation (forest and grassland), the soil retention service and sandstorm prevention service increased by 66.92% and 8.59% between 2000 and 2015, respectively. Correspondingly, the ecological risk of soil erosion decreased by 8.8%, and wind erosion remained stable. Despite the negative impacts from agricultural development on sandstorm prevention, the increase in vegetation and improvement in ecological quality led to a decrease in the ecological risks of soil erosion and sandstorm erosion by improvement of ecosystem services. This research provides a new perspective for ecological risk assessment, as well as direct management information on ecological risks, by incorporating ecosystem services.

“…The problems of nutrient pollution in rivers due to diffuse agricultural sources were also studied in order to determine the capacity of the landscape to mitigate the transmission of diffuse source pollution toward the water bodies, including for nitrates [30,44,50,51] and for phosphates [30,44,50]. Erol and Randhir [30] also considered some point sources of pollution such as septic tanks.…”

Challenges in Using Hydrology and Water Quality Models for Assessing Freshwater Ecosystem Services: A Review

et al. 2018

Abstract:Freshwater ecosystems contribute to many ecosystem services, many of which are being threatened by human activities such as land use change, river morphological changes, and climate change. Many disciplines have studied the processes underlying freshwater ecosystem functions, ranging from hydrology to ecology, including water quality, and a panoply of models are available to simulate their behaviour. This understanding is useful for the prediction of ecosystem services, but the model outputs must go beyond the production of time-series of biophysical variables, and must facilitate the beneficial use of the information it contains about the ecosystem services it describes. This article analyses the literature of ad hoc approaches that aim at quantifying one or more freshwater ecosystem services. It identifies the strategies adopted to use disciplinary-specific models for the prediction of the services. This review identifies that hydrological, water quality, and ecological models form a valuable knowledge base to predict changes in ecosystem conditions, but challenges remain to make proper and fruitful use of these models. In particular, considerations of temporal and spatial scales could be given more attention in order to provide better justifications for the choice of a particular model over another, including the uncertainty in their predictions.

“…These studies can be broadly traced along two main classifications: (1) the theoretical and methodological research on ecological risk assessment, such as defining ecological risk assessment and factor identification [18][19][20][21]; (2) research on assessing negative impacts that are caused by toxic chemicals from various construction projects [22,23]. A "three-step method", namely problem formation, risk analysis, and risk characterization, has recently been developed to greatly improve studies of ecological risk assessment.…”

Ecosystem deterioration has been and is still a serious threat to human survival and regional economic development. Theoretical and methodological challenges exist in assessing ecological risk of watershed ecosystem that is imposed by natural changes or human activities. To fill this research gap, this research proposes an interdisciplinary and quantitative methodology based on some techniques such as the Procedure for Ecological Tiered Assessment of Risk (PETAR), the Entropy, and the Celluar Automata Markov (CA-Markov). We focused on six vulnerable environmental variables, namely land-use change, water quantity, water quality, gross domestic product (GDP), environmental pollutants, and soil erosion in the Huai River watershed in the Henan Province in order to build multi-dimensional quantitative method. Further, the Coupling Coordination Degree Model is constructed, and the "threshold index" is also addressed to reflect the limitation of ecological risk. Our results show that the spatio-temperal distribution of the eco-environmental quality has greatly varied across this study area during different time spans. Natural eco-environmental quality has moderately degraded in 70% of this study area (mainly agricultural region), at a prefectural level from 2000 to 2010, and has slightly improved over the agricultural region (<170 m above sea level) during 2010-2015. However, when considering negative stressors from human social system on the natural ecosystem, the extent and distribution of the ecological risk varied across the whole area during 2000-2015. The results show that there was almost 90.40% of this region under the ecological risk, with varying extents over the study time, e.g., Kaifeng, Shangqiu, Xuchang, and Xinyang, with a moderate deterioration in the eco-environmental quality, and Zhengzhou with a slight deterioration in the eco-environmental quality. This paper provides a valuable perspective for governments at all levels to manage watershed environment resources.
