SUMMARY:Webinar: Hydrography90m\, pushing the boundaries of computational hydrology
DESCRIPTION:An open webinar on hydrology by the guest speaker Giuseppe Amatulli from Yale University.\n\n\nJoin this free webinar & contribute to the open-source community!\n\nREGISTER & LIVESTREAM HERE! \nHydrography90m: pushing the boundaries of computational hydrology \nStreams and rivers drive several processes in hydrology\, geomorphology\, geography and ecology. A global starized hydrographic network that accurately delineates streams and rivers\, along with their topographic and topological properties\, is needed for worldwide environmental applications. Using the MERIT Hydro Digital Elevation Model at 90m and by employing a suite of GRASS GIS hydrological modules\, we calculated the range-wide upstream flow accumulation and flow direction to delineate a total of 1.6 million drainage basins and extracted globally a total of 726 million unique stream segments with their corresponding sub-catchments. Besides\, we computed stream topographic variables comprising stream slope\, gradient\, length\, and curvature attributes as well as stream topological variables to allow for network routing and various stream order classifications. The validation shows that the newly developed Hydrography90m has the highest spatial precision and contains more headwater stream channels compared to three other global hydrographic datasets. \nMore information at https://doi.org/10.5194/essd-14-4525-2022 & https://hydrography.org/ \nREGISTER & LIVESTREAM HERE! \n\n\n\n\nAbout Giuseppe Amatulli\nDr Amatulli is a passionate forester and spatial modeller by training (M.Sc. & PhD in GeoScience and Forestry) and a computer scientist by trade. His research activity is mainly dedicated to spatial modelling\, GIS and remote sensing with special emphasis on tspecies distribution model\, areal distribution and potential shift under climate change conditions\, wildland fire occurrence and pattern recognition\, and wildfire risk assessment based on human and bio-physical parameters. \nUltimately\, he is dealing with geomorphology and hydrography analysis to derive high-accuracy flow estimation. He is daily dealing with high-resolution data in the context of complex and modern modelling techniques using stand-alone implementation processes under Linux environment. He uses open-source programming language and software (GRASS\, R\, PYTHON\, GNUPLOT\, AWK\, BASH\, QGIS\, OPENEV\, CDO) to accomplish large data processing in cluster processing keeping always in mind the ecological and geophysical aspects of the research study. He supports the use of open-source for geocomputation and machine learning modelling giving dedicated courses using (and maintaining) the www.spatial-ecology.net web page. \nREGISTER & LIVESTREAM HERE!

SUMMARY:Global Land Use and Land Cover Monitoring: Main Products and Major Perspectives
DESCRIPTION:About:\n\nAs the global population grows\, humankind continues to modify the land use and land cover (LULC) of the planet mainly motivated by the increasing demand for food and commodities production.  \nIn the last 50 years\, about 17% of land use on the Earth’s surface has changed\, an unprecedented conversion of natural landscapes modifying climate regimes\, reducing biodiversity and contributing to the overall global warming. This process has been under close monitoring for many decades through satellites orbiting the Earth (e.g. Landsat-8\, Sentinel-2\, PROBA-V)\, responsible for frequently delivering updated image data on a global scale. Thanks to the recent advances in Machine Learning\, high processing/cloud computing and remote sensing have allowed multiple research institutes to transform this large imagery archive into LULC mapping products\, contributing to a better understanding of the drivers behind land conversion and their impacts on the global environment. \nIn this discussion panel\, you will learn more about the main LULC products produced by the World Resource Institute\, the University of Maryland and Wageningen University\, including their methodology\, characteristics\, applicability\, limitations as well future perspectives. During the discussion\, the audience will have the opportunity to ask questions and make comments on specific topics. \nFollow the live stream with: \n\nMonitoring the pulse of the planet’s land and its nature-based carbon – Fred Stolle (World Resources Institute)\nGlobal land cover change and human impact on natural land – Matthew Hansen (University of Maryland)\nAdvancements in European efforts in global land cover mapping and map updating – Dainius Masiliunas and Nandika Tsenbazar (Wageningen University and Research)\n\nGeneral information:\n\nThis discussion forum is free-of-costs and can be followed in person or  via Teams’ streaming service;\nTo follow the live stream\, register on Eventbrite: https://www.eventbrite.com/e/global-land-use-and-land-cover-monitoring-main-productsmajor-perspectives-tickets-344785862797\nThe event is organized by the OpenGeoHub foundation in collaboration with Wageningen University;\nAfter the discussion panel\, we invite the participants to join the Happy Hour at the Spot bar (Orion building\, ground floor).

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.
