Los riesgos y peligros a los que estamos expuestos vuelven vulnerables a las poblaciones. Por ello, conocer qué territorios representan mayor peligro a fin de ayudar en la planificación y reducción de daños es el objetivo del Sistema de Información Sobre Peligros y Riesgos (SISPER), una plataforma web desarrollada por científicos de distintas especialidades de ...

Finding and removing land mines is an excruciatingly slow process. Human deminers scour contaminated ground inch by inch with handheld metal detectors, waiting for the telltale beep of a magnetic anomaly. Although trained dogs are sometimes used, metal detectors have remained the go-to clearance method since the end of World War II. “There’s a very ...

The University of Córdoba is participating in the creation of the first database that harmonizes the recording of disturbances caused by insects and diseases in forests in 8 European countries by combining remote sensing, satellite images and field data. Forest damage caused by insects and diseases is increasing in many parts of the world due ...

Global water resources are stretched by climate change and human population growth, and farms and cities are increasingly turning to groundwater to fill their needs. Unfortunately, the pumping of groundwater can cause the ground surface above to sink, as the aquifers below are drained and the architecture of the ground collapses. For the first time, ...

Científicos de la Universidad de Málaga evidencian que los caballos son buenos indicadores para anticipar su aparición en humanos. Se trata de un patógeno emergente en España que se transmite de aves a personas a través de las picaduras de mosquitos. El virus del Nilo Occidental es un patógeno emergente en España que se transmite ...

Over the next few weeks, NASA aircraft will fly over South Africa’s Greater Cape Floristic Region and collect ultraviolet, visual, thermal and other imagery of its terrestrial and aquatic ecosystems. These preliminary images will be publicly available and posted online here within hours of the aircraft landing each day. Combined with satellite imagery and field ...

Lidar technology improvements will help NASA scientists and explorers with remote sensing and surveying, mapping, 3D-image scanning, hazard detection and avoidance, and navigation. Light detection and ranging, or lidar, is a remote sensing technology related to sonar and radar. Lidar uses pulses of light to measure distances and properties of objects accurately, by measuring the ...

A Japanese research team recently published a paper outlining an innovative approach to surveying using Unmanned Aerial Vehicles (UAVs), commonly known as drones. The drones collect topographic and architectural data, which are used to create 3D computer-generated images. The researchers aim to enhance the method’s accuracy by fine-tuning the coordination of hardware and data. This ...

La producción de papa, uno de los tubérculos más importantes para la canasta básica diaria familiar de los colombianos, además de presentar desafíos como el incremento de los costos de transporte e insumos para su cultivo que afectan el bolsillo de los productores, es constantemente vulnerable a que la sobreoferta, producto muchas veces de la ...

Un enfoque que destaca la conservación de la diversidad floral natural como base para la alimentación de las abejas melíferas, es el que tiene el proyecto “Sensores remotos y apicultura natural regenerativa”, que desde 2022 desarrollan investigadores de INIA Quilamapu en la región de Ñuble. El investigador y director del proyecto, Marcelino Claret, indicó que ...

A new study, using a first-of-its-kind approach to analyze satellite imagery from boreal forests over the last three decades, found that fire may be changing the face of the region in a way researchers did not previously anticipate. Historically, fires in North American boreal forests have led to coniferous trees being supplanted by deciduous trees, ...

Korea Institute of Civil Engineering and Building Technology (KICT, President Kim Byung-suk) has developed building scan to BIM (Building Information Modeling)-based reverse engineering technology required for 3D geospatial information modeling domains such as digital twin information modeling. Scan to BIM-based reverse engineering technology was studied to prevent errors and rework caused by manual work when ...

Monterey Bay, California, is known for its beaches. Big Sur in the north is a favorite destination among surfers, and Moss Landing in the south is a bird-watchers paradise. But just off the coast lies a stunning geographic landscape that few know about—and even fewer have seen with their own eyes. It’s called the Monterey ...

Cal Poly Humboldt students and faculty across various disciplines are embarking on an ambitious project to map out vegetation in the Klamath Mountains. This data will have many applications, including understanding how vegetation regenerates after fires, and how plant communities are being affected by a drying and warming climate. In the long term, this project ...

In the southwest of Colombia lies the department of Nariño, known for its majestic mountains that give rise to one of the world’s most excellent coffees, thanks to its unique qualities and characteristics.

Deutschlands Bevölkerung lebt überwiegend in Städten, für die eine enge Bebauung und eine hohe Bevölkerungsdichte charakteristisch sind. Verkehrsprobleme und urbane Hitzeinseln sind häufig damit einhergehende Begleiterscheinungen. Dabei zeigt sich allerdings eine hohe Variabilität: So ist der urbane Hitzeinseleffekt zwar grundsätzlich in hoch verdichteten Innenstädten stärker ausgeprägt, aber auch dort mag ein kleiner Park mit viel ...
