Nation-Wide Monitoring Campaign of 53 Contaminants of Emergent Concern in Surface Waters and Sediment (EMNAT 2018): Occurrence and PNEC Exceedance Evaluation

International audienceThe overall objective of the 2018 campaign to monitor substances of emerging concern in surface water (continental and coastal) and sediment, known as EMNAT 2018, is to provide the exercise of prioritization of emerging substances, which is being carried out in 2020, with monitoring data. This exercise should make it possible to update the list of relevant substances to be monitored (SPAS) as part of future WFD monitoring programmes, which will be implemented in the next water body management cycle (2022).This campaign, led by Ineris, collected nearly 14,000 data regarding 53 substances of emerging concern (36 biocides and 17 surfactants, selected by the Prioritization Experts Committee) in surface water and sediments on a total of 98 sites in metropolitan France and in the overseas departments and regions (DROM). Frequencies of quantification and concentration levels were determined and discussed. Warning indicators, calculated from PNEC (predicted no-effect concentrations), allowed to estimate the criticality of the risk of exceeding them (frequency and degree of PNEC exceedance).Regarding impregnation levels in the environment, with respect to surfactants, Linear Alkybenzene Sulfonic acids (LAS) were the most frequently quantified substances and at the highest median concentrations in water and sediment samples, in metropolitan France and in the DROM. Regarding biocides, fipronil was the most frequently quantified substance in water samples in metropolitan France and in the DROM, but at lower median concentrations than other biocides. Methyl nonyl ketone was the most frequently quantified substance and at higher median concentrations in sediment samples from metropolitan France and in the DROM.Based on the available PNECs, the highly critical substances with respect to exceeding the PNEC are:- LAS C11, C12 and C13 in mainland and the DROM water and sediment samples, - methyl nonyl ketone in mainland and the DROM sediment samples, - fipronil and methylisothiazolinone in mainland water samples, and - fipronil, octylisothiazolinone, methyl nonyl ketone and a triethanolamine based esterquat in mainland sediment samples

Quelle contribution des agroéquipements et du numérique à l’agroéocologie ?

International audienceL’agroécologie a été choisie par l’Inra comme l’un des chantiers de prospective interdisciplinaire destiné à identifier les fronts de recherche en réponse à de grands défis sociétaux. Quatre-vingt chercheurs ont dressé un bilan, et proposé des pistes de recherche pour l’agroécologie, et cet ouvrage en synthétise les principales conclusions. L’agroécologie, en tant que discipline scientifique, remettant l’écologie au centre de la conception des systèmes agricoles, est maintenant bien présente. Diversifier le vivant dans des agroécosystèmes est une visée à large spectre, pour les rendre plus robustes, plus résilients. Les recherches en génétique et en écologie du paysage sont mobilisées pour que l’agroécologie utilise des leviers de la parcelle au paysage. La modélisation des systèmes agroécologiques se développe pour mieux comprendre les interactions biotiques et abiotiques multiples, les prédire, et commencer à piloter certains systèmes. La diversification du vivant dans la production agricole (espèces, variétés, successions culturales, etc.) conduit à des produits plus variés. Les conséquences seront importantes sur les filières, ou plus exactement sur les systèmes agri-alimentaires, allant du mode de production aux produits consommés. Ces changements s’inscrivent sur le long terme. La transition agroécologique, adaptative, se coconstruisant avec les acteurs, est en soi un sujet de recherche, et pourra s’appuyer sur des dispositifs expérimentaux, des exploitations agricoles, des territoires d’innovation

An evolution towards scientific consensus for a sustainable ocean future

International audienceThe ocean has recently taken centre stage in the global geopolitical landscape. Despite rising challenges to the effectiveness of multilateralism, attention to ocean issues appears as an opportunity to co-create pathways to ocean sustainability at multiple levels. The ocean science community, however, is not sufficiently well organised to advance these pathways and provide policy input. The Intergovernmental Panel on Climate Change and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services demonstrate how knowledge consensus and integration have been instrumental in charting global pathways and eliciting commitments to address, respectively, climate change and biodiversity loss. An equally impactful global platform with a thematic focus on ocean sustainability is needed. Here we introduce the International Panel for Ocean Sustainability (IPOS) as a coordinating mechanism to integrate knowledge systems to forge a bridge across ocean science-policy divides collectively. The IPOS will enrich the global policy debate in the Ocean Decade and support a shift toward ocean sustainability
