Season Three of 'A Window on Science' features interviews with individuals who contribute to Open Science and the study of Invasive Alien Species. In S3, E4, Joris Timmermans from the University of Amsterdam, part of LifeWatch Netherlands, talks about EBVs, Essential Biodiversity Variables and why they are useful.

We live in a world of big data, enormous amounts of information collected from numerous satellites that circle the Earth at a distance of 800 kilometres, data which far exceeds the average person's capacity to interpret them. To make clear to policy makers which data, from where, are important, the many parameters of Satellite Remote Sensing have to be simplified into the variables most relevant to a given case of biodiversity research. Integration and harmonisation of these data with other sources of data requires a process of homogenisation based on these most essential descriptors. The LifeWatch ERIC cutting-edge technologies allow us to combine standardised observation over long periods of time to determine which factors are assisting or resisting invasions of alien species.
