A courageous scientist, able to change course of things when she was almost finishing her degree in Environmental Sciences, constant in focusing her efforts and time on geographical standardization once she detected she was passionate about it. This temperament characterizes CREAF researcher Alaitz Zabala and, to a large extent, has led her to specialize in advanced research on geographic information systems (GIS) and remote sensing, and to teach at the Autonomous University of Barcelona on these disciplines.
The European NewLife4Drylands project aims to apply nature-based solutions (NBS) to restore degraded and desertified lands, using remote sensing data and models. From CREAF we contribute with the experience of two research teams: the Protecsòls group, for the restoration of degraded landscapes, and the Grumets group, for environmental remote sensing.
A group of specialists in remote sensing applications in the water sector and in the fields of research, engineering and political decision making define the necessary services and future missions related to water of Copernicus, the observation program of the land of the European Union and the European Space Agency. This is the main axis of the European Water-ForCE research project. At CREAF, the main researcher involved is Lluís Pesquer, as well as the researchers Ester Prat, Cristina Domingo and Joan Masó, all of them also members of the GRUMETS research group.
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.
