More than 90% of Earth's agricultural land will be degraded by 2050, according to the recent article ‘Let’s #StopSoilErosion to ensure a food secure future' published by the United Nations Food and Agriculture Organization (FAO). A degraded soil is infertile and can seriously reduce its agricultural performance. Recovering the fertility of degraded land is therefore essential for a region to move towards greater food sovereignty.
The Life-Polyfarming regenerative agriculture project, coordinated by Planeses and CREAF, has recently published six videos in which they explain, in an informative tone, the agricultural and livestock techniques carried out in the pilot farm in La Garrotxa, Catalonia. These techniques aim to recover fertile and profitable soil in a way that respects the environment.
A CREAF-led European study published in the journal Global Change Biology warns that the drought associated with climate change could reduce soil fauna diversity and slow the decomposition of leaf litter (fallen leaves, twigs, bark, etc.), potentially hindering the recycling of nutrients for plants throughout Europe.
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.
Today, May 25, the Joint Research Centre (JRC) publishes the Global Soil Biodiversity Atlas, first-ever of this topic. It’s a European Comission iniciative, available and free for everyone who is interested in. This atlas maps the soil biodiversity of the entire planet by providing an exhaustive analysis of soil organisms and the threats it has to face. Soil management could help the mitigation of the effects of climate change.
CREAF researchers uncover how climate change-provoked substitutions of pines with holm oak affect soil respiration10 de March 2016Albert Naya i Díaz
Scots pine is the tree species with the greatest latitudinal distribution between Siberia and the Iberian Peninsula. The death of these pines due to drought does not affect CO2 emissions from forest soil.
