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…
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…
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…
Landslide inventory and rockfall risk assessment of a strategic urban area (Palermo, Sicily)
2019
This study concerns the assessment of the rockfall risk for two strategic sectors of the Mount Pellegrino, one of the most relevant place in the city of Palermo. During the last two decades, several rockfalls affected the study area setting up a serious threat to the people, structures and infrastructures preventing the economic and social development. For these landslides a detailed GIS inventory was realized; the most dangerous rockfalls occurred within the two study sectors. In both areas we have carried out detailed field surveys and the geo-mechanical characterization of the rock slopes. These analyses allowed to define the rock mass parameters, the set of discontinuities and the kinem…
Urban drainage and sustainable cities: how to achieve flood resilient societies?
2012
This paper tries to describe the main developments of urban flood forecasting and modelling. Currently, several new technologies are available for flood monitoring, modelling and mitigation and several paradigms suggest the adoption of greener approaches to urban storm water management. These tools and new approaches can be easily adaptable to new developments where the entire urban drainage system can be suited to follow a more sustainable way to drain storm water. The challenge for the future is instead aimed to apply this new philosophy to existing urban areas where the application of new tools and technologies requires high costs and such approaches have to be prepared by constructing a…
Environmental mitigation hierarchy and biodiversity offsets revisited through habitat connectivity modelling.
2020
International audience; Biodiversity loss is accelerating because of unceasing human activity and land clearing for development projects (urbanisation, transport infrastructure, mining and quarrying …). Environmental policy-makers and managers in different countries worldwide have proposed the mitigation hierarchy to ensure the goal of “no net loss (NNL) of biodiversity” and have included this principle in environmental impact assessment processes. However, spatial configuration is hardly ever taken into account in the mitigation hierarchy even though it would greatly benefit from recent developments in habitat connectivity modelling incorporating landscape graphs. Meanwhile, national, Euro…

2014
Zudin, Rodion Analysis of information risk management methods Jyväskylä: University of Jyväskylä, 2014, 33 p. Information Systems, Bachelor’s Thesis Supervisor: Siponen, Mikko A brief overview in the information risk management field is done in this study by introducing the shared terminology and methodology of the field using literature overview in the first chapter. Second chapter consists of examining and comparing two information risk management methodologies proposed by two different guides: Risk Management Guide for Information Technology Systems by National Institute of Standards and Technology and The Security Risk Management Guide by Microsoft. By finding common factors and methods…
Up with ecology, down with economy? : The consolidation of the idea of climate change mitigation in the global public sphere
2018
Building on theories of valuation and evaluation, we develop an analytical framework that outlines six elements of the process of consolidation of an idea in the public sphere. We then use the framework to analyse the process of consolidation of the idea of climate change mitigation between 1997 and 2013, focusing on the interplay between ecological and economic evaluations. Our content analysis of 1274 articles in leading newspapers in five countries around the globe shows that (1) ecological arguments increase over time, (2) economic arguments decrease over time, (3) the visibility of environmental nongovernmental organizations as carriers of ecological ideas increases over time, (4) the …
