The increase in drought episodes and the lack of water in the soil have favored Mediterranean species. At the same time, conifers are losing ground because they are less adapted to droughts. These trends correspond to the period of 1987 to 2012 and have been confirmed through satellite remote sensing images.
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.
Ivette Serral has a degree in Environmental Sciences from the UAB and has been working as a technician in remote sensing and GIS at CREAF since 2002. She is currently a member of the GRUMETS research group and participates in the ConnectinGEO and Ecopotential projects. The diversity of her day to day work is stimulating, though it also makes it hard to put her mind to analysis of data and results.
A study carried out by scientists at the CREAF and the CSIC has shown that the reflectance PRI index allows for the quantification of gasses emitted by plants in order to communicate or in situations of stress. This index is calculated by measuring the light that vegetation reflects with the help of photosensors on planes or with satellite images.
The information captured by Landsat-8 will be published and will serve to advance the research, study and management of our planet, in particular, in the pursuance of agriculture, forest, water consumption or energy management.
