Artificial intelligence is revolutionizing environmental monitoring, offering powerful tools that enhance our understanding and management of ecosystems. Using artificial intelligence, scientists and conservationists can accurately monitor vast and remote areas, predict future environmental changes and implement effective conservation strategies. A cutting-edge study by researchers at the Remote Sensing Center at the Institute of Geodesy and Cartography used satellite technology to monitor plant stress in extensive wetlands, offering key insights into ecosystem health under the pressure of climate change. The study, published in the journal Ecological Informatics, introduces a pioneering approach to estimating the chlorophyll fluorescence parameter Fv/Fm using Sentinel-2 satellite imagery, a parameter that is crucial for assessing plant photosynthetic performance, especially under stressful conditions such as drought or excess water [1].
Chlorophyll fluorescence is an indicator of how well a plant performs photosynthesis. By analyzing this parameter from space, we can detect areas where vegetation may be under stress due to environmental factors without having to set foot in the field [1].

The study was conducted on peatlands in the Biebrza Valley in Poland and the Cepkeliai marshes in Lithuania. These areas are known for their complex ecosystems, which play a significant role in biodiversity conservation and carbon sequestration. Using the XGBoost machine learning algorithm, the team successfully mapped Fv/Fm differences in these wetlands [1]. The algorithm’s ability to efficiently process voluminous satellite data allowed for precise and detailed monitoring of large areas.
The accuracy we achieved with our machine learning model was robust, showing strong correlation with ground data. This method not only enhances our ability to monitor wetlands, but also helps us effectively manage these critical habitats [1].

Application of AI
Artificial intelligence, particularly machine learning algorithms such as XGBoost, has the ability to process and analyze vast amounts of data from satellite imagery with high efficiency and accuracy. This is crucial in environmental monitoring, where data sets are large and complex, involving various spectral indices and temporal changes.
In the context of wetland monitoring, AI helps accurately estimate the chlorophyll fluorescence parameter Fv/Fm, a key indicator of photosynthetic activity and plant health. By analyzing these parameters, AI can pinpoint areas where plants are under stress due to environmental factors such as extreme water conditions, pollution or habitat degradation.
AI-based tools make it possible to scale monitoring efforts to cover vast areas of wetlands around the world without extensive physical field work. This not only reduces the costs associated with traditional monitoring methods, but also allows for frequent and repeatable assessments, providing up-to-date information on the status of these ecosystems.
Artificial intelligence models can learn from historical data to predict future wetland conditions, offering valuable information on proactive conservation measures. By understanding patterns and potential stress events before they occur, conservationists and decision-makers can implement strategies to mitigate negative impacts, thereby increasing the resilience of these critical habitats.
Artificial intelligence can be integrated with other technological advances, such as hyperspectral imaging and drones, to improve the detail and accuracy of ecological assessments. This holistic approach to ecosystem monitoring is key to addressing the complex and dynamic nature of wetlands.
While artificial intelligence offers significant opportunities for ecological monitoring, there are challenges that need to be addressed, such as the risk of over-fitting models to specific data sets, the need for significant training data, and ensuring that AI models are interpretable. In addition, integrating AI with ecological science requires interdisciplinary collaboration to ensure that algorithms are tailored to meet the diverse needs of environmental monitoring.
Developments in satellite technology
This study represents a significant advance in ecological monitoring, using Earth observation technologies under the Ramsar Convention to protect wetlands of international importance. The insights gained can help policymakers and conservationists make more informed decisions, ensuring that wetlands are resilient to the effects of climate change. In light of these findings, the researchers highlight the potential for integrating satellite monitoring systems with traditional conservation efforts to provide a comprehensive understanding of the ecological dynamics and plant health of global wetlands.
