New research from the University of Oxford and the University of Exeter examines savanna biome distribution and drivers through the lens of tree cover across India. Using remote sensing (the process of monitoring the physical characteristics of an area by measuring its radiation, typically from a satellite), the study analyses tree cover across forests and ...

In recent years, environmental justice researchers have uncovered wide disparities in exposure to toxic pollutants between people living in low-income neighborhoods and those living in wealthier communities. Much of the research has focused on air pollution emitted from factories, along with diesel truck and automobile exhaust from highways—which are generally situated far from high-income neighborhoods. ...

Según los investigadores, el aumento de las temperaturas junto con ...

Remote sensing plays a vital role in monitoring agricultural landscapes, yet current satellite sensors often struggle with the trade-off between spatial and temporal resolution. High spatial resolution images, while detailed, are often limited by infrequent captures and cloud interference, reducing their utility in rapidly changing environments. Conversely, images with better temporal resolution lack the necessary ...

This invention presents a Wi-Fi Positioning System (WPS) that enables accurate indoor positioning via Wi-Fi signals, as GPS is often unreliable indoors. By employing novel data generation techniques, this system enhances the data collection process. It is applicable to products requiring indoor positioning, such as navigation, augmented reality and health applications. Indoor positioning is crucial ...

Crust and lithospheric mantle—the thinnest and thickest layers of the Earth’s lithosphere—and a wide range of dynamic processes that deform them can be studied by using high precision geodetic data taken directly from Global Navigation Satellite Systems (GNSS). GNSS data and data products can measure and help the user understand such factors as the Earth’s ...

As the planet continues to warm due to human-driven climate change, accurate computer climate models will be key in helping illuminate exactly how the climate will continue to be altered in the years ahead. In a study published in the Journal of Geophysical Research: Atmospheres, a team led by researchers from the UC Irvine Department ...

The Earth’s spin axis is not constant. It moves slowly over time relative to the Earth’s crust. This is caused by various processes on the surface and inside the Earth, such as the melting of ice masses or the uplift of land masses, as well as mass shifts in the Earth’s viscous mantle and core. ...

Most people interact with maps regularly, for example, when they’re trying to get from point A to point B, track the weather or plan a trip. But, beyond those daily activities, maps are also increasingly being combined with artificial intelligence to create powerful tools for urban modeling, navigation systems, natural hazard forecasting and response, climate ...

Forests in Galicia, northwestern Spain, are frequently ravaged by wildfires, leading to significant environmental and economic damage. The increasing virulence of these fires, exacerbated by climate change, poses a heightened risk to both natural landscapes and human populations. Traditional forestry methods to mitigate these fires are costly, prompting the exploration of alternative measures. One such ...

Mangroves are crucial for biodiversity, climate change mitigation, and coastal protection but face threats from climate change and human activities. Traditional monitoring methods fall short in accurately capturing their complex features. The integration of advanced machine learning algorithms with multisource remote sensing data offers a promising solution. Based on these challenges, it is essential to ...

Hundreds of monumental stone heads dot the coastline of the remote Pacific island of Rapa Nui, or Easter Island. Settled by a small group of Polynesian seafarers about 900 years ago, it’s a fascinating place that has been the subject of fierce debate about how complex societies can sometimes ruinously fail. Some experts, such as ...

Researchers at the University of Southampton have conducted the most detailed spatial analysis to date of storm surges along the coast of the UK and Ireland. The oceanographers found that coastlines in the north of the Irish Sea experience the longest and largest surges, while those occurring around the southwest coast of England have the ...

The impacts of climate change are being felt all over the world, but how will it impact how your hometown feels? An interactive web application from the University of Maryland Center for Environmental Science allows users to search 40,581 places and 5,323 metro areas around the globe to match the expected future climate in each ...

Un estudio liderado por el Centro de Investigación PEGASO de la Universitat Politècnica de València (UPV) advierte de la “emergente necesidad” de identificar medidas preventivas que ayuden a garantizar la conservación de los edificios patrimoniales y a mejorar la gestión turística de dichos inmuebles y de los centros históricos de las ciudades. Realizado en el ...

Researchers at the University of Bonn have developed software that can simulate the growth of field crops. To do this, they fed thousands of photos from field experiments into a learning algorithm. This enabled the algorithm to learn how to visualize the future development of cultivated plants based on a single initial image. Using the ...

A new machine-learning system developed at the University of Alaska Fairbanks can automatically produce detailed maps from satellite data to show locations of likely beetle-killed spruce trees in Alaska, even in forests of low and moderate infestation where identification is otherwise difficult. The automated process can help forestry and wildfire managers in their decisions. That’s ...

In the late 2000s, Scott Saleska observed an unusual phenomenon in the Amazon rainforest. A severe drought in 2005 led to increased green growth in vast areas of the Amazon, contrary to field researchers’ observations of browning plants and some dying due to the drought. Recent research published in Nature by Shuli Chen, a doctoral ...
