New publication on the impact of management on soil carbon sequestration

Mushrooms on forest soil

A new study, developed in the framework of the HoliSols project, was recently published on Forest Ecology and Management.

The publication synthesises information on forest management practices that can mitigate climate change by increasing soil carbon stocks and reducing greenhouse gas emissions. The study also identifies soil processes that affect soil greenhouse gas balance and discusses how models represent forest management effects on soil in greenhouse gas inventories and scenario analyses to address forest climate change mitigation potential.

Enjoying the trainee experience with HoliSoils

Trainee in the field

Among the many people involved in HoliSoils, there are also young researchers and trainees who are increasing their knowledge and skills through the activities of this project. Jakub Tomes, a trainee at Natural Resources Institute Finland (Luke) involved with HoliSoils’ field experiment in Finland, described his experience with these words:

“As a part of a LUKE’s working group I participated in measuring GHG emissions from forest soils. We measured CO2 and methane fluxes with LI-COR devices across southern Finland on different sites such as Tammela and Nastola. And also as a member of LUKE’s team I was helping with taking deep core samples and soil samples seeving from drained peatland at Ränskalalankorpi.

This traineeship has given me better and deeper understanding of respiration of forest soils. I have learned how to work with LI-COR and the traineeship has helped me cope with problems in the field conditions fast.

I hope I will have the opportunity to be a part of their team again.”

Researchers propose ectomycorrhizal fungi’s role to be integrated into carbon accounting 

Mushroom

Researchers from the University of Helsinki, Natural Resources Institute Finland and Swedish University of Agricultural Sciences propose that the role of the ectomycorrhizal fungi should be taken into account in models of carbon accounting.

A new study led by the University of Helsinki provides evidence that the observed decline of carbon use efficiency and net ecosystem exchange from south to north in the boreal forest may be caused by the abundance of ectomycorrhizal fungi. 

The proposed approach could easily be included in carbon balance models for quantifying ectomycorrhizal fungi carbon use without having to engage in more complex analysis of carbon and nutrient interactions underlying ectomycorrhizal fungi processes. 

“The results of the study underline the need for a better understanding of the role of micro-organisms as users of carbon but also as a machinery generating carbon residues that may have longer lifespans,” says the first author of the study Annikki Mäkelä from the Faculty of Agriculture and Forestry, University of Helsinki. 

The study suggests that this approach can improve prediction of biomass growth across different soils with different microbial composition.  

More accurate prediction of biosphere carbon sinks

According to researchers these features of ectomycorrhizal fungi as carbon consumers and litter producers should also be incorporated into global vegetation models in order to have more precise and accurate prediction of biosphere carbon sinks and their feedbacks to climate change.  

Carbon use efficiency, i.e., the ratio between net and gross primary production, describes the efficiency of vegetation to accumulate photosynthetic carbon to biomass. Other uses of carbon include maintenance and construction respiration. In this study, ectomycorrhizal fungi were included as additional consumers of plant-originating carbon.

Adopting a holistic approach to maximise forest-based climate change mitigation

Wood construction

The European Forest Institute published a new study with the title Forest-based climate change mitigation and adaptation in Europe in the From Science to Policy series. This analysis focuses on the role of forests and wood use in contributing to mitigate climate change. The 12 authors from 7 different countries conclude that European forests and wood products can play a crucial role in achieving climate neutrality by 2050. However, their potential is not enough to compensate for a lack of actions in other areas.

In particular, the study focuses on the role of forests in the removal of green house gas emissions. Moreover, the authors investigate how to maximise the effectiveness of forests contributions to climate change mitigation and adaptation. The study recommends the adoption of a holistic approach, where multiple forest-base mitigation actions are combined to foster synergies, interactions, co-benefits, and regional applicability.

Description

The European Union has set ambitious targets to reduce greenhouse gas emissions by at least 55% in 2030 and to become climate neutral by 2050. The European Forest Institute organised a ThinkForest event to explore what forests can contribute to achieving these climate goals.

Forests and forestry play three important roles in climate change mitigation. First, reducing deforestation and forest degradation lowers GHG emissions. Second, forest management and restoration can maintain or enhance forest carbon stocks and sinks. Third, improving the use of wood products can store carbon over the long-term, and avoid emissions by substituting emissions-intensive materials.

Our ThinkForest event will ask:

  • How much can forest-based activities contribute to climate change mitigation?
  • What role do policies play?
  • How can we maximise forest-based climate change mitigation nationally/locally?

In this occasion, the coordinator of the ForestPaths-project, Hans Verkerk, will present a new study titled “Forest-based climate change mitigation and adaptation in Europe”.

Review on greenhouse gas reporting in European forest soils

Makowski & Wellbrock poster

In the framework of the HoliSoils project, the Thuenen Institute is working on the soil monitoring framework. In particular, their work focuses on reviewing European GHG reporting in forest soils, developing guidelines for harmonized soil sampling methods for future reporting and providing a server for open-access harmonized European maps of forest soil properties. Furthermore, they developed a survey for GHG experts to gain their suggestions for improvement concerning GHG reporting.

Their work mainly focuses on carbon (C) data from forest soils remaining forest soils and differentiates between mineral and organic soils. On this poster, Vera Makowski and Nicole Wellbrock give an overview of the most important findings of the review process and the resultant actions within HoliSoils.

How soil can help save the world

Forest Soil

Soil science is not usually considered the most exciting discipline by the general public. Many people – including in the science world – have underestimated what is beneath our feet.

However, we are now in the International Decade of Soils, and it is time to shine a light on the role of soil in providing food security, supporting biodiversity and mitigating climate change. This article from the BBC showcases how Pete Smith, Professor of Soil and Global Change at the University of Aberdeen, makes the study of soil appealing, for instance, considering how wetlands and peatlands are the “Cinderella” of climate change mitigation.

Read on to find a myriad of ways in which soil can indeed help save the world.
