Land Degradation, Cultural Ecosystem Services, and Ecosystem Disservices in the Sumapaz Páramo, Colombia: An Integrated Socioecological Assessment

Land Degradation &Development, EarlyView.
ABSTRACT Understanding the relationships among land degradation, ecosystem functioning and human well‐being is essential for conserving tropical high‐mountain ecosystems. This study examined the relationships among land degradation, Cultural Ecosystem Services (CES), ecosystem disservices (EDS) and visitor perceptions at Laguna Colorados in the Sumapaz

Conventional to Deep Learning Methods for Hyperspectral Unmixing: A Review

Remote Sensing
Hyperspectral images often contain many mixed pixels, primarily resulting from their inherent complexity and low spatial resolution. To enhance surface classification and improve sub-pixel target detection accuracy, hyperspectral unmixing technology has ...

Optimizing Soil Organic Matter Estimation Through Multi‐Factor Zoning and Tree‐Based Automated Learning

Land Degradation &Development, EarlyView.
ABSTRACT Soil organic matter (SOM) is a key indicator of land degradation and soil functioning. It plays an essential role in nutrient cycling, soil structure, and long‐term agroecosystem resilience. The variations of surface cover, soil moisture and soil texture heterogeneity will affect the accuracy of SOM remote sensing mapping. This study developed

Joint power control and user grouping mechanism for efficient uplink non‐orthogonal multiple access‐based 5G communication: Utilising the Lèvy‐flight firefly algorithm

IET Networks, EarlyView., 2023
We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

Spatial–Spectral Decoupling-Enhanced Lightweight Network for Few-Shot Hyperspectral Anomaly Detection in Remote Sensing Imagery

Remote Sensing
Hyperspectral anomaly detection (HAD) identifies targets by spectral differences. However, large deep learning models overfit under the small-sample conditions typical of remote sensing, where anomalies are sparse and annotations costly.

Coordinated motion of UGVs and a UAV [PDF]

, 2013
Coordination of autonomous mobile robots has received significant attention during the last two decades. Coordinated motion of heterogenous robot groups are more appealing due to the fact that unique advantages of different robots might be combined to ...

Aerial Seeding for Forest and Landscape Restoration: A Systematic Review of Technology, Challenges, and Future Directions

Land Degradation &Development, EarlyView.
ABSTRACT Land degradation is a critical global challenge, threatening biodiversity, food security, and livelihoods. Ecological restoration has therefore become a priority, with aerial seeding emerging as a key method to address issues of scale, accessibility, and efficiency. By dispersing seeds from aircraft or drones, aerial seeding complements ground‐
