Challenges of Urban Artificial Landscape Water Bodies: Treatment Techniques and Restoration Strategies towards Ecosystem Services Enhancement

Abstract

With the rapid adoption of green infrastructure and nature-based solutions for a low-impact development, much consideration is given to ecosystem services and the ecological enhancement in modern planning of urban spaces. Artificial landscape water bodies have, in recent years, been utilized to enhance the ecological quality of urban environments. As an environmentally friendly measure, the water source of these waters has predominantly been adopting reclaimed water (treated wastewater). As a result, landscape water bodies are often eutrophic, exhibiting poor hydrodynamics, with lengthy water change cycles, creating the ideal environment for algal blooms that negatively impact the aesthetic appeal of these landscape waters. Based on the existing literature, this paper summarizes the treatment techniques and strategies employed in enhancing the quality of urban artificial landscape water bodies and providing integrated design solutions in the urban environment.

Mechanisms and Applications of Nature-Based Solutions for Stormwater Control in the Context of Climate Change: A Review

“…Empirical evidence substantiates NbSs' role in addressing urban hydrological challenges, including runoff modulation and flood mitigation, while offering cost-effective alternatives to conventional methods [39,40]. Additionally, NbSs' assimilation into urban landscapes augments ecological vitality, offering a spectrum of ecosystem services [41].…”

Advances in ecotechnological methods for diffuse nutrient pollution control: wicked issues in agricultural and urban watersheds

“…With the goal of optimizing purification performance while limiting ecological risks, many scholars have evaluated the potential of exploiting the advantages of the combining or integrating several purification processes (Addo-Bankas et al, 2022). Table 1 illustrates different purification strategies, their corresponding purification mechanisms, and the advantages and disadvantages of each strategy.…”

“…In an effort to alleviate the movement of NPS inorganic pollutants from land to freshwater systems and preserve peaceful, aesthetically appealing waterbodies while reducing their public health threats, natural resources managers and rural councilors have implemented a variety of control strategies and technologies over the years with varying degrees of success (Kumwimba et al, 2018;Xue et al, 2020;Addo-Bankas et al, 2022). However, most of these strategies concentrate more on treatment, rather than preventing NPS nutrient pollution, targeting only one contamination side.…”

“…Furthermore, many review articles are restricted to one particular diffuse pollution treatment method (e.g., constructed wetlands, eco-ditches, vegetated buffer zones, retention ponds, etc.). In contrast, very few review papers have been performed to review ecotechnological methods for diffuse nutrient pollution comprehensively (e.g., Addo-Bankas et al, 2022). Therefore, finding an effective solution to organically merge the single approach to include all sides of diffuse nutrient pollution production is essential.…”

Threats of Contamination of Drinking Water Sources and Preventive Enhancement of Protection Efforts of these Sources in the Case Study of the Czech Republic

“…The analysis revealed that cases using an integrated approach to the solution show high ambitions. Nature-friendly solutions, especially green technologies, appear to be attractive tools which might help improve the current situation [25]. Research, which proved that nature-friendly measures mitigate and solve the depletion of sources and climate problems, came to similar results [26].…”
