Die Zürcher Wälder sind wie viele andere Gebiete in Mitteleuropa von Bodenversauerung betroffen. Das Amt für Landschaft und Natur hat rund zehn Prozent der Waldböden im Kanton genauer untersucht und die Ergebnisse in einer digitalen Karte dokumentiert. Für die Bewirtschaftung dieser Wälder, gerade angesichts des Klimawandels, wird die Waldbodenkarte wertvolle Zusatzinformationen geben.

Flying over a dense jungle in southern Venezuela, the sea of trees below is suddenly replaced by large patches of bare soil, tree stumps and the turquoise waters of ponds from abandoned gold mines. An airstrip 600 meters long marks the entrance to one of Venezuela’s more than 3,700 gold mines. Only half of the ...

A team of atmospheric and climatic scientists from several institutions in Europe has found that even if all human management of forestry land stopped immediately, it would not be sufficient to offset global carbon emissions. In their study, reported in the journal Science, the group used mapping and AI applications to model how much forest ...

O estudo foi realizado no distrito de Santo Antônio do Matupi. “Distritos” são unidades administrativas dentro de um município, neste caso o município de Manicoré na porção sul do estado do Amazonas. O distrito de Matupi, também conhecido como “km 180”, está localizado na rodovia Transamazônica (BR-230). Esta estrada principal faz a ligação com o ...

Come ha dimostrato la tempesta Vaia e l’attuale epidemia di bostrico, i cambiamenti climatici possono mettere a dura prova le foreste dell’arco alpino. Anche la programmazione della gestione forestale deve essere affrontata con strumenti al passo con i tempi. In Provincia di Bolzano l’intera superficie forestale viene gestita attraverso strumenti di pianificazione decennali attraverso circa ...

High-resolution satellite imagery has been used to map every single tree in Africa, demonstrating a technique that could help improve the monitoring of deforestation across the world. Florian Reiner at the University of Copenhagen, Denmark, and his colleagues used images from satellites operated by US firm Planet and machine-learning models to map canopy cover across ...

Um novo mapeamento da superfície queimada pelo fogo no Brasil revela que a área queimada entre 1985 e 2022 foi de 185,7 milhões de hectares, ou 21,8% do território nacional. A média anual alcança 16 milhões de hectares/ano, ou 1,9% do Brasil. São extensões comparáveis a países: no caso do acumulado em 38 anos, a ...

Researchers from the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS) have found that the proportion of sunlit background visible in remote sensing images controls the vertical distribution of stereoscopic point clouds. The higher the proportion of visible sunlit background, the stronger the ability to detect the understory terrain. The team ...

Eine biobasierte Wirtschaft, die sich an natürlichen Kreisläufen orientiert, nachhaltig und klimaneutral ist – das ist das Ziel der Bioökonomiestrategie der Bundesregierung. Doch entwickelt sich die Bioökonomie in allen Bereichen in die gewünschte Richtung? Die Nutzung von Biomasse kann zu Zielkonflikten führen, die nicht immer auf den ersten Blick sichtbar sind, weil sie global oder ...

More than 7% of all mountain forests have been destroyed during the past two decades, according to a new study published in the journal One Earth. Using high-resolution satellite data and maps of mountain terrains, researchers found that 780,000 square kilometers (301,000 square miles) of mountain forest were lost worldwide between 2001 and 2018. The ...

Novo estudo de dez anos, revisado por pares, sugere que as florestas administradas por Indígenas na Amazônia Brasileira absorvem milhares de poluentes de gases venenosos provenientes de incêndios florestais, evitando 15 milhões de dispendiosos casos de doenças todos os anos. Com base em uma análise de dados de dez anos, os autores do novo estudo ...

As cities continue expanding, forested areas are becoming scarcer, and less dense. That’s bad news for the wildlife that call those areas home. A University of Cincinnati doctoral student is studying what local areas are important to North America’s largest woodpecker. “The pileated woodpecker is not considered as a vulnerable species, but it is an ...

Türkiye on Friday released a map of the projected distribution of trees and the migration of forests around the country’s internal Marmara Sea until the end of this century. The initiative was part of a project carried out to explore the potential of the northwestern forests in the Marmara region to adapt to climate change. ...

Brazil has ousted almost all illegal gold miners from the Yanomami territory, its largest indigenous reservation, and will remove miners from six more reserves this year, the head of the federal police’s new environmental crimes division said on Tuesday. Enforcement operations supported by satellite imagery and aerial photography have destroyed 250 miner camps – many ...

The Thünen Institute now offers interactive forest maps through the Thünen Atlas (http://atlas.thuenen.de) that provide a nationwide overview of the stocked forest area—i.e., the area on which trees grow—and the dominant tree species. The digital maps have a resolution of 10m x 10m. The map of dominant tree species is based on data from the ...
