Können wir durch großflächige Wiederbewaldung den Klimawandel stoppen?

Letzte Woche hat das Magazin Science eine viel beachtete Studie der Arbeitsgruppe von Prof. Crowther vom Institut für Integrative Biologie der ETH Zürich publiziert, in der mithilfe von Satellitenaufnahmen, Felddaten und Computermodellen das enorme Potential von großflächiger Waldvermehrung für den globalen Klimaschutz herausgestellt wurde.

Das Besondere an dieser Studie ist der Fokus auf „Restoration“, also Wiederbewaldung. Es gibt viele Abschätzungen zu CO2 Minderungspotenzialen durch Aufforstungen, und es ist wichtig, bei solchen Abschätzungen den Landbedarf einer wachsenden Weltbevölkerung sowie aus anderen Sektoren realistisch abzuschätzen (Canadell and Schulze 2014). Die Autoren der Studie haben daher von der global theoretisch möglichen Waldfläche den Flächenbedarf für Landwirtschaft und Siedlungen abgezogen. Als Resultat ergab sich eine riesige Fläche von fast 1 Mrd ha für potenzielle Wiederbewaldung.

rescEU put into practice!…partially.

The current heat wave does not only create a feeling of summer holidays but above all, it puts fire and rescue services as well as foresters on constant alert.

At the same time, the rescEU plan is getting into its next phase, which is good news. RescEU is the common European response to disasters by strengthening the EU’s collective ability to react.

Especially in consideration of the high risks of forest fires, the Commission has launched the first fleet of firefighting aircraft under the new rescEU systems, consisting of two aircraft from Croatia, one aircraft from France, two aircraft from Italy, two aircrafts from Spain, and six helicopters from Sweden. The Commissioner for Humanitarian Aid and Crisis Management Christos Stylianides stated: “With rescEU, we have put words into action. We have delivered a practical tool for citizens that can save thousands of lives in the future. RescEU means having a much stronger, pan-European civil protection system.”

Deadwood management in production forests

Written by Lucie Vítková

“Deadwood has a major role for the conservation of saproxylic species and contributes to carbon sequestration, nutrient supply, natural regeneration and protection against falling rocks.” (Lachat et al., 2013:92)*

A substantial amount of literature on the importance of deadwood in Central European forests has been available providing partial recommendations to enhance deadwood-dependent biodiversity. However, a comprehensive review of science- and forestry experts-based recommendations effectively enhancing deadwood bearing in mind operational implications has not been presented in international literature.

Wald-Wild-Klima! In Brandenburg haben sich die Wildbestände seit 1957 mehr als verzehnfacht

Anlässlich des 10-jährigen Bestehens des Landesbetriebs Forst Brandenburg gratulierte Forststaatssekretärin Carolin Schilde in Ihrem Grußwort allen Verantwortlichen und betonte dabei die Bedeutung des Waldumbaus in Zeiten des Klimawandels.

Noch sind 500.000 ha des Brandenburger Waldes reine Kiefernbestände. Die Folgen der Kiefernreinwirtschaft seit ihrem Beginn vor über 200 Jahren werden auch erst in Generationen zu bewältigen sein. „Forstleute wissen, dass eine Beimischung von zirka zehn (Prozent) Laubholz bereits wesentlich dazu beiträgt, dass Massenvermehrungen von Kiefernschadinsekten einzudämmen. Uns allen muss klar sein, dass der aktive Waldumbau mit Fördermitteln keine flächendeckende Lösung sein kann“, fasste die Staatssekretärin zusammen.

Spirituality of the urban forest

Written by Joshua Amaitum Elukut

“When we pay attention to nature’s music, we find that everything on earth contributes to its harmony.” – Hazrat Inayat Khan

Twenty first century cities are characterized by tall skyscrapers, high residential densities, improved public transport infrastructure, as well as buildings of historical heritage. More people are moving from rural to urban areas, with the proportion of global urban population set to increase from 14% in 1900 to over 66% in 2025.

It is unfortunate that despite this trend, many urban areas lack adequate green infrastructure thus the ratio of green areas to built up areas is low. This gives inhabitants the feeling that they live in a ‘concrete jungle’ and are divorced from the natural world, contrary to earlier times when trees had a dominant influence upon human life and were sacred in many cultures.  

Learn, grow, protect – environmental education in urban forest

Written by Vera Knill

„Don’t underestimate the ability of children to help drive change!“ Jo Sayers (The Mersey Forest)

Urban forests serve as a biodiversity hub and enhance resilience to environmental changes. As one of the most significant ecosystems for CO2 reduction from the atmosphere, forests do not only mitigate climate change. They also increase societal benefits, improve the quality of life and shelter the declining species of manifold flora and fauna. To spread this knowledge and to preserve and restore forest ecosystems, education for sustainable development is key.

Integrated forest management case study: Boreal Forests

Part 1. Boreal Forests

The North remembers! Or does it? Winter was coming when I traveled to Scandinavia this January to conduct interviews on integrated forest management. For those less familiar with forestry jargon, this term describes a forest management characterized at attaining multiple outputs from the same forest, sometimes even the same stand. The term is very broad and needs to be specified further before it can be applied. In the case of the INFORMAR project, on which I will write here, we assess the application of nature conservation measures into forestry.

Irish Marteloscopes: learning from each other’s experiences

A workshop took place at the Agriculture and Food Development Authority (Teagasc), Oak Park, Carlow in Ireland mid-February 2019 to allow for a professional exchange on how Marteloscopes are used for training and education. Around 15 workshop participants representing Teagasc, Coillte, the Forestry Division of the Department of Agriculture Food and Marine (DAFM), the Irregular Silviculture Network (ISN) and EFI discussed the potential for cooperation involving both new Irish Marteloscopes sites and those of the existing Marteloscope network.

The Forest Biodiversity Programme METSO – voluntary forest conservation and management in private forests

During the meeting of the European Network Integrate in Toruń, Poland, Sanna Kasurinen, from the Finnish Forest Centre, presented the METSO-programme, an initiative aiming to halt the ongoing decrease of biodiversity of forest habitats and species in Finnish forests. The Forest Biodiversity Programme in particular addresses private forest owners. The overall objective is that based on a voluntary agreement, nature conservation is enhanced and communication improved on biodiversity of forest habitats and ecosystem services amongst stakeholders.

The bridge between nature and art at Triennale of Milan

by Silvia Abruscato

What does a scientist think when an artist is trying to express his/her creativity?  And, what does an artist create when he/she wants to represent a scientific concept?

“XXII Triennale di Milano Broken Nature: Design takes on Human Survival” is a thematic exhibition in the heart of the city of Milan, put into effect by the Triennale Milano. It is the right place to find possible answers to the questions above, to get inspired and fully immersed into it. Artists, designers and architects, from all over the world exhibit their interpretations of the connection and inter-relation between nature and humans.
