1 Introduction
Aquatic ecosystems, encompassing freshwater bodies such as rivers, lakes, wetlands, and coastal areas, are among the most diverse and productive environments on Earth. However, they are also some of the most threatened due to anthropogenic pressures, including pollution, habitat destruction, and climate change. The health of these ecosystems is crucial not only for maintaining biodiversity but also for providing essential ecosystem services such as water purification, flood regulation, and recreational opportunities. Monitoring and managing the health of aquatic ecosystems have thus become imperative to ensure their sustainability and resilience (Schofield et al., 2018).
The importance of monitoring and management in aquatic ecosystems cannot be overstated. Effective monitoring provides critical insights into the long-term changes and current status of these ecosystems, enabling the identification of emerging threats and the assessment of conservation efforts. Various methods have been developed for the hydromorphological, physical-chemical, and biological monitoring of surface waters, which are essential for sustainable water management and the achievement of global sustainability goals such as the United Nations Sustainable Development Goals (SDGs) (Forio and Goethals, 2020). Ecosystem-based management (EBM) approaches have also been advocated to integrate biodiversity conservation with ecosystem service provision, emphasizing the need for a holistic, social-ecological perspective in environmental management (Langhans et al., 2019).
By synthesizing findings from multiple studies, this study highlights innovative monitoring techniques, such as the use of constructed treatment wetlands for enhancing biodiversity and ecosystem services, and the concept of freshwater ecosystem mosaics (FEMs) that emphasize the connectivity and dynamic nature of aquatic habitats. Additionally, this study discusses the challenges and opportunities associated with implementing these advanced methods in the context of global environmental change, particularly in maintaining the biodiversity and ecosystem services of lakes and other freshwater bodies. Through this comprehensive analysis, the study seeks to provide actionable insights for policymakers, researchers, and practitioners dedicated to the sustainable management of aquatic ecosystems.
2 Technological Advances in Monitoring
2.1 Remote sensing technologies
Remote sensing technologies have significantly advanced the monitoring of aquatic ecosystems, providing critical data for managing water quality and ecosystem health. Hyperspectral sensors, such as PRISMA and DESIS, have been utilized to retrieve water quality parameters across various aquatic environments, including deep clear lakes and river dammed reservoirs. These sensors offer high spatial and spectral resolution, enabling detailed analysis of water bio-physical parameters and supporting management decision-making (Bresciani et al., 2022). Additionally, remote sensing has been applied to monitor submerged aquatic vegetation (SAV), which is crucial for ecosystem health but challenging to study due to water column effects. Techniques to correct for these effects have been developed, enhancing the accuracy of remote sensing in aquatic environments.
2.2 In-situ monitoring tools
In-situ monitoring tools have evolved to provide real-time data on water quality and ecosystem health. Biological early warning systems (BEWS) that monitor the behavior and physiological parameters of aquatic bioindicator species have been developed to detect sudden changes in water quality. These systems offer continuous monitoring and early warning capabilities, which are essential for timely management interventions (Bownik and Wlodkowic, 2021). Additionally, high-frequency environmental sensing tools have expanded the ability to measure aquatic ecosystem metabolism, providing insights into gross primary productivity and ecosystem respiration. These measurements are valuable for understanding ecosystem function and informing environmental management (Jankowski et al., 2021).
2.3 Molecular and genetic techniques
Molecular and genetic techniques, such as environmental DNA (eDNA) sequencing, have become integral to monitoring aquatic ecosystems. These techniques allow for the detection and monitoring of a wide range of organisms, including those that are difficult to observe using traditional methods. eDNA sequencing can trace the presence of various species, providing comprehensive data on biodiversity and ecosystem health. This approach is particularly useful in deep-sea ecosystems, where traditional monitoring methods are challenging and costly (Aguzzi et al., 2019).
2.4 Data analytics and artificial intelligence
The integration of data analytics and artificial intelligence (AI) has revolutionized the monitoring and management of aquatic ecosystems. AI and machine learning algorithms can process large datasets from remote sensing and in-situ monitoring tools, providing actionable insights for conservation and management. Automated monitoring systems facilitated by AI reduce data processing bottlenecks and long-term monitoring costs, enabling more effective and timely decision-making. Furthermore, advances in machine learning and cloud computing allow for the exploitation of the full electromagnetic spectrum, enhancing the ability to monitor and assess aquatic environments (Dierssen et al., 2021).
3 Policy Frameworks for Aquatic Ecosystem Management
3.1 International policies and agreements
International policies and agreements play a crucial role in the management and conservation of aquatic ecosystems. The United Nations' Sustainable Development Goals (SDGs), particularly SDG6 (clean water and sanitation) and SDG15 (life on land), provide a global framework for sustainable water management and the protection of terrestrial and freshwater ecosystems (Forio and Goethals, 2020). These goals emphasize the need for integrated monitoring and assessment methods to support sustainable development and ensure the health of aquatic ecosystems. Additionally, international agreements such as the Ramsar Convention on Wetlands and the Convention on Biological Diversity (CBD) set guidelines and targets for the conservation and sustainable use of aquatic resources, promoting international cooperation and the sharing of best practices.
3.2 National regulations and guidelines
National regulations and guidelines are essential for implementing international policies at the country level. In the United States, for example, the Clean Water Act provides a regulatory framework for maintaining and restoring the chemical, physical, and biological integrity of the nation's waters (Jankowski et al., 2021). This includes the use of high-frequency environmental sensing and statistical approaches to monitor aquatic ecosystem metabolism, which can inform environmental management practices. Similarly, European countries have adopted the Water Framework Directive, which aims to achieve good ecological status for all water bodies through comprehensive monitoring and management strategies (Jankowski et al., 2021). These national regulations often incorporate advanced technologies and methodologies, such as the Internet of Things (IoT) and smart monitoring systems, to enhance the accuracy and efficiency of aquatic ecosystem assessments (Glaviano et al., 2022).
3.3 Local management practices
Local management practices are critical for addressing specific environmental challenges and ensuring the effective implementation of national and international policies. Local initiatives often involve the use of integrated assessment frameworks that consider multiple indicator species and various biological communities to evaluate the health of aquatic ecosystems (Zhao et al., 2019). For instance, the use of smart buoy networks (SBNs), autonomous underwater vehicles (AUVs), and multi-sensor microsystems (MSMs) allows for real-time monitoring and adaptive management of coastal and marine environments (Glaviano et al., 2022). These technologies enable local managers to respond promptly to environmental changes and potential threats, thereby enhancing the resilience and sustainability of aquatic ecosystems.
3.4 Stakeholder involvement and community engagement
Stakeholder involvement and community engagement are fundamental components of effective aquatic ecosystem management. Engaging local communities, stakeholders, and indigenous groups in monitoring and conservation efforts can lead to more sustainable and inclusive management practices. For example, the use of IoT-based environmental assessment systems can facilitate community participation by providing accessible and transparent data on water quality and ecosystem health (Narmadha et al., 2023). Additionally, involving stakeholders in the development and implementation of management plans can help ensure that diverse perspectives and knowledge systems are considered, leading to more comprehensive and effective conservation strategies. Collaborative efforts between scientists, policymakers, and local communities are essential for achieving long-term sustainability and resilience of aquatic ecosystems (Zhao et al., 2019). By integrating international policies, national regulations, local management practices, and stakeholder involvement, we can develop a holistic approach to monitoring and managing aquatic ecosystem health. This integrated framework will support the sustainable use and conservation of aquatic resources, ensuring their continued provision of essential ecological services for human and environmental well-being.
4 Integration of Technology and Policy
4.1 Case studies of successful integration
The integration of technology and policy in monitoring and managing aquatic ecosystem health has shown promising results in various case studies. For instance, the H2020 project AQUACROSS has successfully unified policy strategies, knowledge, and management concepts of freshwater, coastal, and marine ecosystems to support the EU Biodiversity Strategy to 2020. This project embraced ecosystem-based management (EBM) to protect biodiversity and sustainably harvest ecosystem services, demonstrating the utility of EBM in safeguarding aquatic biodiversity (Langhans et al., 2019). Another example is the use of IoT technology for environmental assessment, where sensors and Arduino micro-controllers were employed to measure variables such as pH, Total Dissolved Solids, dissolved oxygen, and CO2. This approach has proven effective in tracking the health of aquatic ecosystems and informing policy decisions for their protection. Additionally, the One Health approach, which integrates human, fish, and environmental health, has been applied to manage trace metal contamination in aquatic ecosystems. This approach uses statistical tools to identify contamination sources and pathways, assess health risks, and establish robust monitoring programs (Izah et al., 2023).
4.2 Challenges in integration
Despite the successes, several challenges hinder the effective integration of technology and policy in aquatic ecosystem management. One significant challenge is the need for frequent sensor calibration and ensuring data accuracy in IoT-based monitoring systems. Sensor malfunction and data loss can also pose risks to the reliability of the monitoring data (Narmadha et al., 2023). Another challenge is the limited application of advanced biomonitoring approaches, such as the SPEcies At Risk of pesticides (SPEAR) index, in tropical regions, which restricts the global applicability of these methods (Sumudumali and Jayawardana, 2021). Furthermore, the complexity of integrating multiple biological communities into a single assessment framework can lead to uncertainties in the results, as seen in the integrated assessment of ecosystem health using multiple indicator species. The need for high-frequency monitoring and the alignment of manual sampling with automatic and remote sensing methods also present logistical and technical difficulties.
4.3 Best practices for effective integration
To overcome these challenges and enhance the integration of technology and policy, several best practices can be adopted. First, incorporating redundancy in sensor systems and using machine learning algorithms for data analysis can improve the reliability and accuracy of IoT-based monitoring. Second, expanding the application of advanced biomonitoring approaches, such as the SPEAR index, to tropical regions can enhance the global applicability of these methods. Third, developing a comprehensive framework that integrates multiple biological communities and compensates for uncertainties in single-index assessments can provide a more holistic view of ecosystem health (Zhao et al., 2019). Additionally, adopting a holistic water monitoring approach that combines manual sampling, on-site automatic high-frequency monitoring, and remote sensing can facilitate more informed decision-making and adaptive water resource management (Yang and Zhang, 2019) (Figure 1). Finally, fostering collaboration between policymakers, scientists, and stakeholders is crucial for the successful implementation of integrated monitoring and management strategies. By addressing these challenges and adopting best practices, the integration of technology and policy can significantly improve the monitoring and management of aquatic ecosystem health, contributing to the sustainable development and conservation of these vital ecosystems.
Yang and Zhang (2019) found that the eDNA-based zooplankton integrity index demonstrates a significant correlation with water quality, with stronger correlations observed in April (R² = 0.38) and November (R² = 0.37) compared to August (R² = 0.20). These findings suggest that zooplankton integrity, as assessed through metabarcoding, is a reliable indicator of water quality. The ecological status, classified according to both the zooplankton integrity index and the water quality index, highlights a gradient from poor to healthy conditions. This classification can help in assessing and managing the ecological health of aquatic environments, showing that higher water quality typically corresponds with healthier zooplankton populations.
5 Case Studies in Monitoring and Management
5.1 Freshwater ecosystems
Freshwater ecosystems are critical for biodiversity and human well-being, yet they face significant threats from land-use changes, climate warming, and pollution. Recent advancements in monitoring technologies and methodologies have provided new insights and tools for managing these ecosystems. For instance, the use of stable isotope analysis and ecological modeling has enhanced our understanding of aquatic plant distribution and interactions within freshwater systems (Cherry and Pec, 2022). Additionally, integrated monitoring approaches that combine hydromorphological, physical-chemical, and biological assessments have been developed to support sustainable water management and the implementation of Sustainable Development Goals (SDGs). Biological monitoring, particularly using macroinvertebrates (Figure 2), has also proven effective in assessing the health of freshwater ecosystems and detecting pesticide pollution (Forio and Goethals, 2020).
Forio and Goethals (2020) found that the process of sustainable water resource management involves a cyclic approach of monitoring, assessment, and management actions. This cycle begins with the assessment of aquatic composition using various indices. Identifying key disturbance variables is the next step, where indicators and evidence are gathered using statistical tools and models. This leads to problem identification and cause determination, which is further validated through lab tests, artificial river tests, and experiments. Management and policy actions are then implemented based on these findings. The final step in the cycle involves restoration and protection measures to maintain or improve water quality, thereby closing the loop and feeding back into continuous monitoring and assessment. This iterative approach ensures the effective management and sustainable development of water resources.
