What is CASCADE about?
One of the most challenging themes in ecology over the last decades is the quest for the understanding of discontinuous changes in ecosystems. Discontinuous shifts have already been observed and analyzed for a wide variety of ecological systems, including lakes, drylands, peatlands, rangelands, marine systems, and musselbeds.
Some of these discontinuous shifts in ecosystems imply undesired and irreversible changes. For example, shallow lakes can suddenly change into eutrophic systems with a large loss in biological diversity.
CASCADE will investigate and analyze a range of dryland ecosystems in southern Europe to obtain a better understanding of sudden shifts in drylands that may lead to major losses in biodiversity and concomitant ecosystem services.
Based on these analyses, CASCADE will develop ways to predict the proximity of the CASCADE’s dryland ecosystems to thresholds in such a way that these predictions can be used by policymakers and land users for more sustainable management of drylands worldwide.

Recently, a photo reportage was made during a fieldwork day in the Aveiro study site in Portugal. The reportage is placed in a slideshow that can be viewed HERE.
The slideshow shows colleagues from the Aveiro team measuring plant parameters, taking soil samples and downloading data from data loggers. The images show a normal field day that is performed on a regular basis, in order to obtain characteristic plant, soil and meteo data that will be used for analysis and modelling during the course of the project. These measurement campaigns are performed throughout all 6 study sites in Portugal, Spain, Italy, Greece and Cyprus.
