Iberian Association of Limnology Meeting, Keynote (virtual)
We are in a time of accelerating global crises, and nowhere is this more evident than in cities. Because they concentrate people and infrastructure and are often found along coasts and rivers or in arid areas, cities are particularly vulnerable to the impacts of extreme, weather-related events. Population aggregation provides many benefits to society, including enhanced collective creativity and economies of scale, but among the detriments is rampant spread of disease, as illustrated by the current coronavirus pandemic. Facing this reality, building resilience for our cities requires diverse strategies that integrate social (S), ecological (E), and technological/built (T) components in a systems (S) approach. It also requires outside-the-box thinking and an emphasis on positive futures. I will present a conceptual framework for SETS integration and an approach for co-creating positive future visions (scenarios) developed and applied in nine North and Latin American cities. Examples from the scenario development process will highlight diverse strategies that address unique challenges across the cities. Closer examination of strategies for flooding will show common approaches across diverse cities. And finally, emergent themes, goals, and strategies will be examined in the context of the pandemic, asking how social, ecological, and technological systems respond and fare under this very different type of threat.
Scientific trajectory: I developed my PhD in Ecology at University of Murcia (2014), where I studied how ecosystems respond to natural and anthropogenic stressors using different approaches. In my first postdoctoral position (Cardiff University, 2015-17) quantifying multiple-stressor effects in European rivers and identifying which river biodiversity aspects best predict ecosystem service delivery in UK upland rivers.
Later, I worked at University of Barcelona the mechanisms explaining river metacommunities at rivers in response to predictable drought.
Currently, I work as a postdoc at University of Minho exploring how climate change impact on river food webs and how this translates into changes in ecosystem multifunctionality.
During these years, I published 23 papers in SCI-journals, and published/edited ~200 outreach posts at my co-managed blog and other media.
Research lines: In my research, I explore the effects of multiple global change pressures on biodiversity and multiple ecosystem functions and services, using a variety of quantitative approaches. Combining taxonomic and trait-based approaches, my studies aim at identifying which ecological mechanisms link multiple-stressors, biodiversity and ecosystem multifunctionality.
My studies cover different ecosystems and organisms (river invertebrates and fishes, coastal plants, vertebrate scavengers) to look for general responses to global change.
PhD. Professor at the Ecology and Environmental Department of Universidad de la República, Uruguay.
Her research focuses particularly on the potential effects of climate warming and land use changes on community structure and trophic dynamics, as well as ecosystem processes, of shallow lakes, streams and reservoirs. Her work involves laboratory and field experiments, field studies and space for time substitution studies.
She has published around 60 papers and several book chapters and edited books. She is Associate Editor of the journals Freshwater Biology, Hydrobiologia, Perspectives in Ecology and Conservation, and Ecología Austral. Collaborates with research groups in Argentina, Brazil, USA, Spain, Denmark, The Netherlands, Turkey.
She got a PhD in Ecology from the University of Rio de Janeiro, in Brazil, in 2012. Her thesis was about carbon emission and sequestration in hydroelectric reservoirs and it was partly developed at Wageningen University in The Netherlands.
Raquel was a post-doc at the Radboud University of Nijmegen, in The Netherlands, where she studied the sinergic effects of warming and eutrophication on the carbon balance of shallow lakes.
At Uppsala University, in Sweden, she worked in an ERC-granted project that aimed to improve the knowledge about the carbon dynamics of tropical reservoirs.
Raquel is interested on the various aspects of the aquatic biogeochemistry. She is part of a leading group on CO2 and CH4 emissions from reservoirs and she has published some pioneer studies on the carbon sequestration by inland waters.
She studies the processes and mechanisms of evolutionary response to climate and other environmental factors with relevance to climate – pollution, anthropogenic land-use. To reconstruct long-term dynamics she applies high throughput technologies to sedimentary archives of inland waters, which have the unique advantage of preserving biological and environmental signals temporally.
Moreover, she applies high throughput technologies to ‘resurrected’ specimens of the keystone species Daphnia magna (waterflea) to identify the molecular mechanisms that enable evolutionary changes through time and space.
Dr Orsini strongly believes in bridging the science/policy divide. To this end, she works on biotechnology solutions for the removal of pharmaceuticals, pesticides and other suspended materials from wastewater and surface water.
The Iberian Association of Limnology has awarded the first Lifetime Achievement Award in Limnology to Professor Dr. Narcis Prat i Fornells for his contribution to the development of Limnology in the Iberian Peninsula.
In the same way this award acknowledges his vast scientific production, his enthusiastic teaching and training dedication, his activity in outreach actions to both society and water resource managers, and his commitment to the conservation of aquatic ecosystems.
He got a PhD in Chemistry from the University of Castilla-La Mancha (Spain) in 2018. His thesis, partially developed at the University of Vienna (Austria), encompassed a multidisciplinary approach to assess the natural attenuation of agricultural pollutants (mainly nitrate) in the Pétrola Lake, one of the most representative saline wetlands in the Castilla-La Mancha region (central Iberian Peninsula).
This study was awarded by the Iberian Association of Limnology in 2020.
Currently, he works in the Section for Aquatic Biology and Toxicology, as part of the recently created Center for Biogeochemistry in the Anthropocene, at the University of Oslo. He is involved in a BiodivERsA project focused on filling gaps in Arctic freshwater biodiversity knowledge, where he combines tools like multi-OMICS or stable isotopes to link diversity (taxonomic and functional) with biogeochemical responses.
Nicolas is especially interested in extreme environments including polar regions (Svalbard, Finse, Finnmark) or hypersaline ecosystems, focused on the high relevance of lakes and ponds in such ecosystems for the global carbon and nitrogen cycles.
Plenary conferences will be live. Presentations (45 minutes) will be followed by 15 minutes for questions and discussion with the speakers. All plenary conferences will be recorded and will be available on the web for viewing.
