The Department of Environment and Natural Resources targets to increase the country’s forest cover by an additional three million hectares by 2028 as part of efforts to minimize the impact of climate change, DENR Secretary Maria Antonia Yulo Loyzaga revealed. “We have four targeted areas for reforestation, 1.2 million hectares that can be made available ...

A research project to capture an inventory of all exotic planted forests in New Zealand could provide a valuable tool for commercial forestry decisions. Crown Research Institute Scion showed Forest Insights at its stand at Mystery Creek in June, as part of the 2024 Fieldays Forestry Hub. Grant Evans is Scion’s new value digital forests ...

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 ...

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 ...

A team of researchers has unveiled a novel approach to accurately characterizing tree height composition in forests using the Global Ecosystem Dynamics Investigation (GEDI) Light Detection and Ranging (LiDAR) technology. This study marks a significant advancement in our understanding of forest ecosystems, shedding light on the intricacies of tree height variability and its implications for ...

Enquanto o governo federal discute a criação de um polo agrícola na confluência entre Amazonas, Acre e Rondônia – popularmente conhecida pelo acrônimo Amacro –, o desmatamento nos municípios da região avança e já representa 76,5% do total da área devastada nos três Estados entre 2018 e 2022. A conclusão é de um estudo publicado ...

Africa’s forested areas—an estimated 14 % of the global forest area—are continuing to decline at an increasing rate—mostly because of human activities to convert forest land for economic purposes. As natural forests are important CO2 and biodiversity reservoirs, this development has a significant impact on climate change and affects the integrity of nature. To intervene ...

Apartir de la catástrofe sobre los recientes incendios forestales que afectaron a distintos sectores de la Región de Valparaíso, nuevamente se ha puesto la atención sobre la eventual relación que tendrían estos siniestros con el interés inmobiliario por ocupar los espacios que fueron damnificados. En el estudio “Construyendo sobre cenizas. ¿Son utilizados los incendios forestales ...

Monitoring deforestation across millions of hectares of Amazonian jungle has always been an onerous ask. When illegal logging first became an issue, the authorities relied on word-of-mouth and reports from indigenous communities, before buzzing the jungle in small planes to find the deforested areas. In the 1980s the first satellite images became available, with resolution ...

The Delhi government has identified and is in the process of digitally demarcating over 2,000 hectares of land and over 450km of roads and drains as deemed forests, the state forest department has said in an affidavit submitted to the Delhi high court last month. A deemed forest is not a notified or a reserve ...

On a hillside overlooking cabbage fields outside the northern Thai city of Chiang Mai, a drone’s rotors begin to whir, lifting it over a patch of forest. It moves back and forth atop the rich canopy, transmitting photos to be knitted into a 3D model that reveals the woodland’s health and helps estimate how much ...

Publication of a new map showing all the above-ground biomass in the Brazilian Amazon is good news in the context of the severe crisis afflicting the world’s largest contiguous tropical rain forest. Using airborne laser scanning and satellite imagery calibrated by field forest inventories and integrated by heavy-duty computer processing and machine learning, the map ...

Norway’s International Climate and Forest Initiative (NICFI) and the Bezos Earth Fund announce a new partnership to continue providing the world with free access to high-resolution satellite data to support efforts to stop the destruction of the world’s rainforests. The partnership adds to the USD 43 million previously granted by NICFI to establish the NICFI ...

Forests, known as nature’s “green dams,” play a crucial role in replenishing Earth’s groundwater reserves. However, overcrowding in planted forests due to lack of maintenance activities, such as thinning practices, is a pressing concern in Japan. This overcrowding causes substantial water loss from these forests into the atmosphere through a combination of soil evaporation and ...

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 ...

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, ...
