Special Issue Information

Dear Colleagues,

Forest degradation and deforestation caused by different drivers (e.g., fire, logging, urbanization, plant diseases/pests, and agriculture expansion) are critical environmental issues that have profound implications for biodiversity, climate change, and ecosystem services across the globe. The integration of Artificial Intelligence (AI) and multi-source remote sensing data has emerged as a transformative approach to monitor and understand these processes with unprecedented accuracy and efficiency. Remote sensing technologies, including optical, radar, and LiDAR systems, provide vast amounts of spatial and temporal data, while AI techniques, such as traditional machine learning, deep learning, and recent remote sensing multimodal large models, enable the extraction of meaningful insights from these complex datasets. This convergence of technologies offers a powerful toolkit for detecting, quantifying, and predicting these forest changes, thereby supporting informed decision-making and sustainable forest management. Given the urgency of addressing global degradation, deforestation, and their associated environmental impacts, this research area has gained significant scientific and societal importance, making it a focal point for interdisciplinary collaboration and innovation. 

This Special Issue, ‘Advances in Forest Degradation and Deforestation Monitoring with AI and Multi-Source Remote Sensing Data’, aims to showcase cutting-edge research that leverages AI and remote sensing to advance our understanding of forest degradation and deforestation. This Special Issue seeks to highlight novel methodologies, tools, and applications that address the challenges of monitoring forest degradation and deforestation across diverse ecosystems and scales. By bringing together contributions from experts in remote sensing, AI, ecology, and environmental science, this Special Issue will provide a comprehensive platform for disseminating innovative solutions and fostering interdisciplinary dialogue. The topic aligns closely with the scope of Remote Sensing, which emphasizes the development and application of remote sensing technologies to address pressing environmental issues. This Special Issue will not only advance the scientific community’s knowledge, but also contribute to global efforts in forest conservation and climate change mitigation. 

We invite submissions that explore a wide range of themes, including, but not limited to, the following: the development of AI-driven algorithms for remote sensing-based forest change detection; the integration of multi-source remote sensing data for enhanced monitoring accuracy of forest disturbances; the application of deep learning techniques in forest degradation and deforestation monitoring; and the use of remote sensing for assessing the impacts of deforestation on biodiversity and carbon stocks. Both original research articles and review papers are encouraged, as well as case studies that demonstrate the practical application of these technologies in real-world scenarios. Additionally, contributions that address the challenges of data availability, scalability, and interpretability in AI-based remote sensing approaches are particularly welcome. By encompassing these diverse themes, the Special Issue aims to provide a holistic perspective on the current state and future directions of forest degradation and deforestation monitoring, ultimately driving progress in this critical field.

Individual Planted Tree Seedling Detection from UAV Multimodal Data with the Alternate Scanning Fusion Method

Detection of planted tree seedlings at the individual level is crucial for monitoring forest ecosystems and supporting silvicultural management. The combination of deep learning (DL) object detection algorithms and remote sensing (RS) data from unmanned aerial vehicles (UAVs) offers efficient and cost-effective solutions. However, current methods predominantly rely on unimodal RS data sources, overlooking the multi-source nature of RS data, which may result in an insufficient representation of target features. Moreover, there is a lack of multimodal frameworks tailored explicitly for detecting planted tree seedlings. Consequently, we propose a multimodal object detection framework for this task by integrating texture information from digital orthophoto maps (DOMs) and geometric information from digital surface models (DSMs). We introduce alternate scanning fusion (ASF), a novel multimodal fusion module based on state space models (SSMs). The ASF can achieve global feature fusion while maintaining linear computational complexity. We embed ASF modules into a dual-backbone YOLOv5 object detection framework, enabling feature-level fusion between DOM and DSM for end-to-end detection. To train and evaluate the proposed framework, we establish the planted tree seedling (PTS) dataset. On the PTS dataset, our method achieves an AP50 of 72.6% for detecting planted tree seedlings, significantly outperforming the original YOLOv5 on unimodal data: 63.5% on DOM and 55.9% on DSM. Within the YOLOv5 framework, comparative experiments on both our PTS dataset and the public VEDAI benchmark demonstrate that the ASF surpasses representative fusion methods in multimodal detection accuracy while maintaining relatively low computational cost.

Land degradation in Iraq’s Mesopotamian plain threatens food security and rural livelihoods, yet the relative roles of climatic water deficits versus anthropogenic pressures remain poorly attributed in space. We test the hypothesis that multi-timescale climatic water deficits (SPEI-03/-06/-12) exert a stronger effect on vegetation degradation risk than anthropogenic pressures, conditional on hydrological connectivity and irrigation. Using Babil and Al-Qadisiyah (2000–2023) as a case, we implement a four-part pipeline: (i) Fractional Vegetation Cover with Mann–Kendall/Sen’s slope to quantify greening/browning trends; (ii) LandTrendr to extract disturbance timing and magnitude; (iii) annual LULC maps from a Random Forest classifier to resolve transitions; and (iv) an XGBoost classifier to map degradation risk and attribute climate vs. anthropogenic influence via drop-group permutation (ΔAUC), grouped SHAP shares, and leave-group-out ablation, all under spatial block cross-validation. Driver attribution shows mid-term and short-term drought (SPEI-06, SPEI-03) as the strongest predictors, and conditional permutation yields a larger average AUC loss for the climate block than for the anthropogenic block, while grouped SHAP shares are comparable between the two, and ablation suggests a neutral to weak anthropogenic edge. The XGBoost model attains AUC = 0.884 (test) and maps 9.7% of the area as high risk (>0.70), concentrated away from perennial water bodies. Over 2000–2023, LULC change indicates CA +515 km2, HO +129 km2, UL +70 km2, BL −697 km2, WB −16.7 km2. Trend analysis shows recovery across 51.5% of the landscape (+29.6% dec−1 median) and severe decline over 2.5% (−22.0% dec−1). The integrated design couples trend mapping with driver attribution, clarifying how compounded climatic stress and intensive land use shape contemporary desertification risk and providing spatial priorities for restoration and adaptive water management.
