SUMMARY:MOOD Science Webinars
DESCRIPTION:Every last Wednesday of the month\, as part of the EU-H2020 MOOD communication and dissemination activities\, OpenGeoHub hosts a series of science webinars inviting two leading experts to share their research work on disease surveillance and modelling in data science\, the impact of global warming on disease outbreaks\, and the building of one-health systems across Europe and the world. With the MOOD science webinars\, we aim at bringing the leading scientists and professionals in the field to discuss important recent discoveries and discuss implications of their work. \nWe especially encourage presentations on published research work focusing on: how was the work implemented? What were the main discoveries? What did and did not work out the way you expected? and what are the implications of the main discoveries\, especially in the context of the MOOD project objectives? \n  \nJoin the next MOOD Science webinar!\nEvery last Wednesday of the month (except August and December)\, from 3 to 4 PM (CET). Click on the button below to join the Zoom meeting using the passcode.\nJoin us on Zoom\nMeeting ID: 890 6145 6726\nPasscode: 038362

SUMMARY:Biodiversity: how big is our global biodiversity debt and what can we do about it?
DESCRIPTION:OpenGeoHub Science seminar series 2021\nAccording to climate-expert prof. Johan Rockström\, human-induced critical loss of biodiversity on land and in oceans is one of the biggest modern-time risks of leading to global ecosystem instability. Loss of biodiversity\, especially in the Tropics\, is one of the 9 tipping points of irreversible climate change and life quality degradation on our planet. We have only a few decades to reverse the negative trends and start valuing biodiversity realistically. i.e. using financial damages and risks also affecting the next generations. But how to measure biodiversity and what is our global biodiversity debt? How much can we learn from the further and closer past? Two biodiversity scientists from the University of Amsterdam and Leiden join us to discuss their discoveries with modelling species dynamics through time using historic data and biogeography. \nRegistration via Eventbrite. \nProgramme:\n15:00–15:20: Introduction to the topic/questionnaire: “what is our (human) global biodiversity debt?”\n15:20–15:50: “Biodiversity: some lessons from the last 100k years” by Dr. Kenneth Rijsdijk\, Universiteit van Amsterdam\n\nIt is long known that the present-day distribution of species (biodiversity) is shaped by geological forces such as mountain formation and drifting of the continents that separated species over millions of years. Also it is well known that present day distributions of plants and animals\, including us\, are the effect of more recent migrations\, be it active (humans) or randomly (seeds). Only recently\, we discovered that sea level fluctuations forced by natural climatic change cycles acting over 100\,000 yrs played a major part in the distribution of organisms across our planet. This research contributes to our understanding of how much change species naturally endured – if we know the baseline rate of natural change\, we can compare it with rates of change induced by humans; and evaluate whether the present-time biota would be able to keep up. \n  \nKenneth is assistant professor at the BIOMAC Research Group of IBED University of Amsterdam. His research is focused on the dynamics of abiotic processes that shape the earth’s surface and affect biota. He is especially interested in how environmental processes affect landscapes and ecosystems.  \nRecent publications: \nRijsdijk\, K.F.\, Hengl\, T.\, Norder\, S.J.\, Otto\, R.\, Emerson\, B.C.\, Ávila\, S.P.\, López\, H.\, van Loon\, E.E.\, Tjørve\, E. and Fernández‐Palacios\, J.M.\, (2014).

Surprisingly\, hotspots of biological and cultural diversity are often found in similar locations. A better understanding of the environmental and societal drivers underlying these patterns is urgent because global biocultural diversity is severely threatened. Species are currently going extinct at rates which largely exceed long-term background rates. The same is true for cultures: the global variation in languages for example\, one aspect of cultural diversity\, is declining rapidly as well. In this talk\, SIetze will discuss the spatial distribution of bio- and cultural diversity\, their drivers\, and how an integrated perspective could provide opportunities for their conservation. \n  \n  \nSietze studies how patterns of biological and cultural diversity have been shaped by interactions between climate\, topography\, and ecology. While he has a background in biogeography\, he is now a postdoctoral researcher at the Leiden University Centre for Linguistics where he applies methods and theories from biogeography to patterns of human cultural diversity and migration. He has recently published a book on island biodiversity called: “The World in Miniature” (currently only available in Dutch; an English summary is available here). \nRecent publications: \nNorder\, S.J.

And which are actually used in decision making / ecosystem accounting?\nWhat is our global biodiversity debt (since pre-industrial time)?\nHow much do international initiatives such as GBIF and ESA EO missions help tackle the problems of biodiversity loss?\nHow important is biodiversity in the time of COVID-19 pandemic (and does it have anything to do with the pandemic)?\nWhat can we learn from the past? Which are currently the best models of biodiversity preservation / regeneration?\nHow will global climate change / global warming affect biodiversity and how much should we worry?\n\nReferences:\n\nSkidmore\, A.
