Catalonia’s agricultural soils contain four years’ worth of carbon emissions

28 de June 2018Albert Naya i Díaz

The soils below dryland crops contain 54% of Catalan agricultural land's 48 million tons of organic carbon, although the highest concentrations are found in rice fields and pastures.

It’s already available CREAF Talk by Scott Ollinger about nitrogen and carbon assimilation in forests

22 de February 2018CREAF

A new video of CREAF Talks conferences is now available. Scott Ollinger, from University of New Hampshire, USA, talks about basic relations among foliar N and CO2 assimilation in forests, relationships between N concentrations and a suite of functionally convergent plant traits that influence canopy reflectance, and implications for broad-scale N mapping and ecosystem—climate interactions.

Thirsty holm oaks lose 21% more carbon through their roots

19 de January 2018Albert Naya i Díaz

Once rehydrated, holm oaks have a large capacity for recovery thanks to their high adaptation to the Mediterranean climate. The release of organic compounds into the soil represents a considerable loss of carbon for the holm oak and also modifies the microbial community, which may lead to additional effects on the tree.

Fossil fuel emissions hit record high after unexpected growth: Global Carbon Budget 2017

16 de November 2017CREAF

The Global Carbon Budget 2017 has analyzed carbon emission sources and sinks worldwide. This year the researcher Benjamin Stocker from CREAF has collaborated in the report contributing and preparing data about how the change in the use we give to the territory has affected CO₂ emissions.

“We invest much more time writing scientific publications than making science accessible”

31 de October 2017Verónica Couto Antelo

Rossella Guerrieri has a PhD in Forestry and Environmental Sciences and has been a post-doc at CREAF since 2016. Her projects are related to the natural cycles of forests and she is a strong advocate of the social impacts of science.

The greening of the earth is reaching its limit

19 de September 2017Albert Naya i Díaz

A new study led by Josep Peñuelas and published in Nature Ecology and Evolution reveals that CO2 abundance in the atmosphere no longer has a powerful fertilizing effect on vegetation. The greening that has been observed in recent years is slowing and this will cause CO2 levels in the atmosphere to rise, thus increasing temperatures and leading to increasingly severe changes in climate.

Achieving the COP21 agreements is currently far-fetched

9 de June 2017Albert Naya i Díaz

The COP21 set the maximum temperature increase for 2100 at 1.5° C. The only scenario which would allow achievement of this goal would require vastly reducing human CO2 emissions, significantly increasing the prominence of renewable energies, and the use of some type of artificial carbon sequestration technology.

Remote sensing of leaf pigments will improve climate change models

7 de February 2017Albert Naya i Díaz

An international team of researchers co-led by Josep Peñuelas (CSIC and CREAF) has developed a new method for monitoring changes in the photosynthetic activity of perennial conifers throughout the year. This new technique, based on the analysis of remote sensing images captured by satellites, will improve global models of atmospheric carbon capture and permit more precise predictions about climate change.

The loss of soil carbon can accelerate climate change

1 de December 2016Albert Naya i Díaz

The journal Nature has today published a study which had the participation of CSIC scientists at CREAF, Marc Estiarte and Josep Peñuelas, which demonstrates the relationship between the release of carbon from soils and the acceleration of climate change.

CO2 absorption in European ecosystems depends on two major climatic phenomena

18 de January 2016Albert Naya i Díaz

The worst scenario occurs when NAO and EA are in opposite phases. This ocurred in the first few years of the previous decade and during this period, the CO2 uptake was below average. Recently, NAO and EA were in the same phase and ecosystems have been able to remove more carbon from the atmosphere.

Degraded land restored with sewage sludge sequester up to 37% more carbon than un-amended land

6 de July 2015Marina Torres Gibert

A study carried out by researchers from CREAF and the UAB shows that restoring degraded land with sewage sludge aids carbon sequestration in the soil. These organic wastes improve soil structure and the growth of plants, and these are eventually incorporated into the soil as soil carbon.

Nutrient-rich forests absorb more carbon

7 de April 2014Anna Ramon Revilla

Thee ability of forests to sequester carbon from the atmosphere depends on nutrients available in the forest soils, shows new research from an international team of researchers,

Nightime global warming limites CO2 uptake by boreal flora

5 de September 2013Anna Ramon Revilla

Nightime temperatures on the planet have increased 1.4 times faster than daytime temperatures. This asymmetry alters carbon fluxes and plant growth in the northern hemisphere, according to a study in which the CREAF is participating.
