Cosavez-vous "Links between Ecosystem Health and Global Health" du 26 juin 2024

During this seminar, we will discuss about the links between ecosystem/habitat health and human/global health through the presentation of two highly interesting talks focusing on original and innovative research to assess the impact of land-use and habitat changes, deforestation, climate change and urbanization on global health, but also on common and innovative tools allowing us to measure ecosystem health and more widely global health.
The first presentation will focus on geotechnologies which have evolved rapidly in recent years, being able to produce, integrate and analyse large volumes and diversity of data. Its application to emerging health problems makes it possible to bring together spatial information on the environment, climate, diseases, the presence of vectors and pathogen reservoirs. However, this approach is not possible without ecological models, which also consider human society as a whole. In this work we will present some examples of spatial data analysis for the identification of leptospirosis transmission hotspots.
The second presentation will focus on bioaerosol (pollen, fungal spores and bacteria) analysis, that plays a crucial role in assessing both ecosystem and human health. Whilst traditional methods provide foundational data on bioaerosol composition and concentrations, they often lack the sensitivity and real-time capabilities required for
comprehensive environmental monitoring. Innovative approaches are now enhancing bioaerosol analysis. AI-driven detection systems, for instance, leverage machine learning algorithms to analyze complex data sets quickly and accurately. Real-time monitoring networks use advanced sensors and fluorescence technology to detect and quantify bioaerosols continuously, offering immediate insights into air quality and potential health risks. Additionally, integrating these technologies with geographical information systems (GIS) enables detailed spatial analysis of bioaerosol distribution, aiding in the prediction and management of health impacts related to air quality. These advancements not only improve our understanding of bioaerosol dynamics but also enhance our ability to protect ecosystems and human health from airborne biological pollutants.

Marine Combe research focuses on assessing the role of biodiversity on the emergence of zoonotic pathogens ("dilution effect"), better understand the diversity and evolution of pathogens present in the environment, in animals and humans, and characterizing the drivers and the risk of zoonotic disease emergence. She is involved in international One Health projects (H2020 BCOMING, PREZODE) in South-East Asia, Africa, Latin America and the Caribbean. She belongs to the Cosav One Health and leads the "science working group".

Speaker: DR. CHRISTOVAM BARCELLOS - BRAZILIAN CLIMATE & HEALTH OBSERVATORY, FIOCRUZ
Christovam Barcellos is a geographer, with doctorate in Geosciences, specialisation in Public Health. Throughout his academic career, Barcellos had remarkable participation in health surveillance activities and government institutions, such as the Rio Grande do Sul Secretary of Health from 2001 to 2005 and the National Health Institute of Mozambique in 2023. Currently, he is a senior researcher at the Health Information and Communication Institute, and professor at the National School of Public Health, in Rio de Janeiro, focusing his researches in health inequalities, climate change impacts on population´s health and geotechnologies applied to environmental health.

Speaker: DR. DAVID O’CONNOR - DUBLIN CITY UNIVERSITY
Dr. David O’Connor is an assistant professor in the School of Chemical Sciences at Dublin City University (DCU).). His primary research interests lie in the fields of atmospheric chemistry and bioaerosol monitoring. Before joining DCU, he held positions at Technological University Dublin and completed post-doctoral fellowships at the University of Denver and University College Cork, focusing on atmospherically relevant species and
processes. Dr. O’Connor’s current projects include the development of an Irish bioaerosol monitoring network aimed at providing real-time data and forecasts on bioaerosol (pollen, fungal spores and even bacteria). These initiative, utilizes laser and fluorescence technology along with AI and machine learning to detect these bioaerosols, which is crucial for individuals with asthma and allergies, as well as for the agricultural sector impacted by plant pathogens. He is also leads the PERMOTOX project (DCU Water Institute)that focuses on the occurrence and sources of persistent, mobile, and toxic (PMT) substances in Irish waters. This project aims to determine the impact, sources, and quantity of PMTs chemicals on water quality.
