Imagining a “post-carbon” future? Climate change as represented by media and film industries
2020
This study explores current trends in representing and communicating climate change by media industries. It reviews the current literature on mainstream media narratives of climate change focusing on their naturalization of progress and their techno-optimism (e.g., as regards geoengineering). It provides insight on how the media industry’s commercial agenda is linked to the types of disseminated messages and dominant imaginaries. It compares respective codes inherent in news media and film/fictional representations of climate change on representative examples. It traces the evolution of disaster/dystopian genres that involve climate issues. It discusses the implications from such a comparat…
Synergies in Design and Health. The role of architects and urban health planners in tackling key contemporary public health challenges
2020
Background and aim: Important public health improvements have been achieved over the past decades, but new challenges are emerging and progress cannot be taken for granted. Urban settlements host most of the global population, but they are also sources of several threats. The aim of the paper is to investigate the role of architects and planners in contributing to overcome these critical health challenges and propose strategic actions for collaboration with the public health workforce. Methods: Taking global trends and public health challenges as starting point, a scoping literature review has been conducted to illustrate the possible synergies that architecture and public health workforce …
La memòria oceànica del clima: El sistema circulatori d'un planeta viu
2013
A principis del segle XVI Leonardo da Vinci comparava els corrents oceànics amb el fl ux de sang d’un cos humà. Actualment disposem d’informació sufi cient per a explorar la idea que la Terra té un sistema circulatori responsable de capturar, transformar i distribuir l’energia solar. El paper dels oceans com a reguladors del clima és extraordinari, realment condicionen el present i el futur del planeta.
After cyclone Aila : politics of climate change in Sundarbans
2023
This article compares the politics of climate change in the Sundarbans region in Bangladesh and India based on ethnographic fieldwork in four villages and among migrants from these villages in Kolkata and Khulna city by focusing on the long aftermath of cyclone Aila. The comparison highlights different policy options and framings of extreme weather events . Ten years after the cyclone, the aftermath of Aila continues in both regions we studied in Bangladesh and India, but partly for different reasons. In our study areas in Bangladesh, the aftermath of Aila reinforced the neglect of coastal livelihoods, whereas, in the communities we studied in India, Aila spurred new investments in the affe…
"Ihmiskunnalle ennen kokematon uhka" : ilmastonmuutoksen poliittiset merkitykset turvallisuus- ja puolustuspoliittisissa selonteoissa ja eduskunnassa…
2020
Artikkelissa tarkastellaan ilmastonmuutoksen turvallisuuspoliittisia merkityksiä Suomessa poliittisen kielenkäytön analyysimenetelmin. Turvallisuus- ja puolustuspolitiikassa uhkakuvat sekä niiden tärkeysjärjestys ja merkitys ovat poliittisen kamppailun kohteena. Käsitteellisellä tasolla esimerkiksi ilmastonmuutoksen turvallisuuspoliittinen merkitys määräytyy poliittisissa debateissa, joissa esitetään argumentteja politiikan linjanvedosta, ratkaisuista ja resursseista. Poliittiseen kielenkäyttöön, käsitteisiin ja argumentteihin keskittyvä analyysimenetelmä on tapa analysoida, missä merkityksissä ja yhteyksissä ilmastonmuutosta on parlamentaarisessa poliittisessa puheessa ja politiikkaa linja…
Città-porto a prova di futuro. Linee guida per l’integrazione di soluzioni basate sulla natura per l’adattamento climatico e la tutela della biodiver…
2023
Quale è il ruolo della pianificazione nel rispondere alle sfide della crisi climatica e della perdita di biodiversità nei contesti urbano-portuali? Il lavoro di ricerca costituisce un avanzamento del dibattito sulla riqualificazione delle aree portuali, contesti storicamente avulsi dalla considerazione di tematiche legate alla preservazione e valorizzazione degli habitat naturali e degli ecosistemi. La tesi desidera mettere al centro della discussione le città porto mediterranee come ecosistemi e come insediamenti urbani multi-specie, come attrici del cambiamento responsabile di fronte alle crisi e non soltanto nodi infrastrutturali strategici per l’economia, la finanza e gli usi militari. …
Priming effect increases with depth in a boreal forest soil
2016
Abstract Climate warming increases labile carbon (C) inputs to soil through increased photosynthesis and C allocation belowground. This could counterintuitively lead to losses of soil C via priming effects (PE): the stimulation of soil organic matter (SOM) decomposition caused by labile C addition. Systematic quantification of PEs in different ecosystems is needed. We measured PEs of free-living soil microbes in different layers of a boreal forest soil, and found that the relative magnitude of the PE increased with soil depth. The relationship between relative PE and the added glucose amount also depended on the soil layer. Our results indicate that the decomposition of SOM in deeper soil l…
Optimizing management to enhance multifunctionality in a boreal forest landscape
2017
The boreal biome, representing approximately one-third of remaining global forests, provides a number of crucial ecosystem services. A particular challenge in forest ecosystems is to reconcile demand for an increased timber production with provisioning of other ecosystem services and biodiversity. However, there is still little knowledge about how forest management could help solve this challenge. Hence, studies that investigate how to manage forests to reduce trade-offs between ecosystem services and biodiversity are urgently needed to help forest owners and policy makers take informed decisions. We applied seven alternative forest management regimes using a forest growth simulator in a la…
The emissions reduction potential of substituting short-haul flights with non-high-speed rail (NHSR) : The case of Finland
2021
Replacing short-haul flights with high-speed rail (HSR) has been widely discussed as one solution to mitigate the climate change impacts of aviation. However, although HSR can provide travel times similar to those provided by short-haul flights, and at lower emission levels, it also requires considerable investments in time and infrastructure to build. Instead, this study considers the feasibility of replacing short-haul flights with existing non-high-speed rail (NHSR). Our study is based in Finland, a country that has an extensive route network of short-haul flights but does not possess any HSR. We compared all 16 city pairs for which short-haul flights are offered with existing NHSR based…
A simple scaling procedure to assess the impact of climate change on extreme precipitation
2017
In this study we used the products of the Regional Climate Models (RCMs) to evaluate the impact of climate alterations on extreme events across the Region of Sicily (Italy). Data have been retrieved from EURO-CORDEX simulations at 12 km of spatial resolution. Because of the low resolution, the RCMs products are likely unsuitable to reproduce consistently sub-daily heavy precipitations. For this reason, extreme events at daily scale were first checked out by comparing the quantiles estimated from raingauge observations and RCMs outputs. Secondly, we implemented a temporal downscaling approach to estimate rainfall for durations of 1, 3, 6, 12, 24 hours from the modeled daily precipitation. La…
