Advanced monitoring of abandoned mining sites with High-Resolution UAV Technology

[Excerpt] In the past decade, unmanned aerial vehicles (UAVs), or drones, have become invaluable tools in the mining industry, supporting applications ranging from mineral exploration to environmental remediation. When equipped with high resolution image sensors, UAVs enable high spatial and temporal resolution surveying, making them particularly effective for monitoring abandoned mining sites. This paper prese...

Assessing microplastic pollution in horticultural soils under greenhouse cultiv...

[Excerpt] The widespread use of plastic materials in intensive agriculture, including greenhouse covers and irrigation systems, raises increasing concerns regarding microplastic (MP) contamination in terrestrial ecosystems. This study aims to characterize and quantify microplastics in greenhouse agricultural soils in the Minho region of northern Portugal, an area of intensive horticultural production. The main ...

Addressing absenteeism through a community of practice in higher education: The...

This article presents Community of Practice for Attendance (CoP +Attendance), awarded funding through the 7th Edition of the University of Minho's Programme to Support Projects for Innovation and Development in Teaching and Learning [2024/2nd Call], coordinated by the IDEA- UMinho Centre, throughout 2025. The CoP +Attendance addresses absenteeism among undergraduate students. The initiative will focus in Geolog...

Assessment of flood hazard potential in the Este River basin using precipitatio...

With increasing urbanization and climate variability, flood risk has become a pressing concern for cities like Braga, located in northwest Portugal, where natural factors such as irregular topography and the presence of the Este River intersect with dense urban development. The Este River basin, characterized by low slope gradients and extensive impermeable surfaces, is particularly prone to sudden flood events...

From waste to resources: UAV monitoring of abandoned mine tailings and critical...

Study of the influence of fluvial dynamics on the distribution and transport of...

The global reliance on water and the exponential increase in plastic production have led to significant microplastic water pollution. The recent COVID-19 pandemic and financial crises have worsened this issue, with rising plastic use polluting aquatic ecosystems and increasing disregard for the environment. Microplastics, polymer particles smaller than 5mm, classified as primary, created with a certain purpose,...

Impact assessment of microplastics in agricultural soils of the Euroregion Gali...

Plastic has become an essential component of modern agriculture. However, studies have shown that plastic waste can adversely affect soil health and biodiversity, soil productivity and food security. As the demand for agricultural land continues to increase and resources become scarce, it is pivotal to prevent further degradation of agricultural soils. Few studies were conducted in the NW of the Iberian Peninsu...

Analysis of spectral separability for detecting burned areas using Landsat-8 OL...

Fire is one of the natural agents with the greatest impact on the terrestrial ecosystem and plays an important ecological role in a large part of the terrestrial surface. Remote sensing is an important technique applied in mapping and monitoring changes in forest landscapes affected by fires. This study presents a spectral separability analysis for the detection of burned areas using Landsat-8 OLI/TIRS images i...

Evaluation of the ability of SLSTR (Sentinel-3B) and MODIS (Terra) images to de...

Forest fires are considered one of the major dangers and environmental issues across the world. In the Cerrado biome (Brazilian savannas), forest fires have several consequences, including increased temperature, decreased rainfall, genetic depletion of natural species, and increased risk of respiratory diseases. This study presents a methodology that uses data from the Sea and Land Surface Temperature Radiomete...

Design and in situ validation of low-cost and easy to apply anti-biofouling tec...

Biofouling is the major factor that limits long-term monitoring studies with automated optical instruments. Protection of the sensing areas, surfaces, and structural housing of the sensors must be considered to deliver reliable data without the need for cleaning or maintenance. In this work, we present the design and field validation of different techniques for biofouling protection based on different housing m...
