Climate change: where are we right now?
2019
15ème Rencontres Bourgogne-Franche-Comté Nature : Changement climatique, humanité et biodiversité; International audience; Greenhouse gases (GHGs), naturally part of the atmosphere, have protected us from severe glaciations in thepast. Today, human activities increase GHG concentrations and cause rapid and unprecedented Earth warming.Climate change is not resumed only to warming, water cycle is also changed. All the researches confi rm: the climateis changing fast, too fast for ecosystems and societies to adapt. Despite the alerts of the international scientifi ccommunity, States gathered into Conferences of the Parties (COP) ratify agreements but do not comply with all theircommitments. Pu…
New insights into the use of rhizobia to mitigate soil N2O emissions
2022
Agriculture is a major anthropogenic source of the greenhouse gas N2O, which is also involved in stratospheric ozone depletion. While the use of rhizobial inoculants has already been reported as an emerging option for mitigating soil N2O emissions, this study presents an in situ abatement of 70% of soil N2O emission using the strain nosZ+ G49 vs. nosZ− USDA138 in association with soybean. Therefore, we consider that the choice of the inoculant strain of a leguminous crop should take into account the capacity of strains to reduce nitrous oxide in addition to their N fixation capacity. This study also clearly suggests that this mitigation option could be considered not only for soybean but al…

EA Pôle MERS. Rapport final de contrat de recherche INRA (communication orale invitée, 46 slides). Présenté le 24 septembre 2013 au BASF SE, Limburgerhof en Allemagne par Cécile Revellin seule. SYMGES – Projet partenarial (2013) – Coordination C. Hénault, UR SOLS Conduit avec l’unité d’Agroécologie de Dijon, en partenariat avec un industriel des biotechnologies agricoles, ce projet étudie la capacité des rhizobia (microorganismes vivant en symbiose avec les légumineuses et possédant la capacité de fixer l’azote) à réduire le N2O en N2 pour utiliser cette fonction microbienne afin de réduire les émissions du gaz à effet de serre par les sols agricoles.

Searching for a robust strategy for minimizing alkali chlorides in fluidized bed boilers during burning of high SRF-energy-share fuel
2015
Abstract To meet the increasing volume of waste to be treated via energy recovery, high SRF-energy-share fuel is being fired in conventional waste-to-energy facilities. In this work, corrosion related risk during firing of 70 e-% share (target fuel) is studied and compared against the base case fuel containing 50 e-% share. Cl and S concentration is highest in the target fuel as a direct result of increasing the proportion of SRF in the fuel mixture. Br, Zn and Pb showed the same trend. Meanwhile, the concentration of Na, K, Al and Si are highly dependent on the type of the SRF fired. The corrosion risk of the base and target fuels are analyzed using the composition of the fine aerosol frac…
A Methodological Approach to Determine Sound Response Modalities to Coastal Erosion Processes in Mediterranean Andalusia (Spain)
2020
Human occupation along coastal areas has been greatly increasing in recent decades and, in many places, human activities and infrastructures are threatened by erosion processes that can produce relevant economic and human losses. In order to reduce such impacts and design sound management strategies, which can range from the &ldquo
Stato dell’arte degli interventi sul mezzo recettore e di propagazione per la mitigazione delle vibrazioni generate da sistemi di trasporto su ferro
2008
La generazione e la propagazione delle onde vibrazionali da una sorgente, ferroviaria o tranviaria, all’ambiente circostante è un problema complesso che risulta influenzato da vari fattori tra loro correlati: le caratteristiche e le condizioni della sovrastruttura, il peso, la velocità e le caratteristiche meccaniche del veicolo, le proprietà dinamiche e stratigrafiche del terreno, le caratteristiche dinamiche degli edifici recettori. Di tali aspetti occorre tenere conto ai fini della realizzazione di efficaci misure di mitigazione. Nella presente memoria vene riportato lo stato dell’arte relativo agli interventi sul mezzo di propagazione (suolo e sottosuolo) e sul mezzo recettore (opere di…
Integral functions of marine vertebrates in the ocean carbon cycle and climate change mitigation
2021
Summary In the last decade, the ocean has absorbed a quarter of the Earth’s greenhouse gas emissions through the carbon (C) cycle, a naturally occurring process. Aspects of the ocean C cycle are now being incorporated into climate change mitigation and adaptation plans. Currently, too little is known about marine vertebrate C functions for their inclusion in policies. Fortunately, marine vertebrate biology, behavior, and ecology through the lens of C and nutrient cycling and flux is an emerging area of research that is rich in existing data. This review uses literature and trusted data sources to describe marine vertebrate C interactions, provides quantification where possible, and highligh…
What is (not) the point of just transition in food systems?
2022
Food systems are confronted with a low-carbon transition challenge. The need for significant emission reductions in industrial food systems implies significant systemic transformations in food production, processing, and consumption. The wide-reaching impacts of such transformations have evoked public discussion and academic research on just transition in food systems. The undisputable legitimacy of the idea of just transition makes it an attractive concept for all food system actors who might be affected by low-carbon transition policies in direct and indirect ways. Some of the claims that are being made are warranted claims for justice, some merely defend the achieved privileges and benef…
