-Wetlands are one of the most biologically productive ecosystems, in which reedbeds of Phragmites australis are an essentially detritus-based system where litter decomposition is a fundamental process. This study represents a three year dataset describing cyclic trends of Phragmites australis leaf litter breakdown in a temporary and managed environment. For three years, 45 days field experiments were seasonally performed, using leaf bag technique within a large managed temporary pond (Natural Reserve of the Isonzo River Mouth, Northeast Italy), in order to analyze spatial and temporal variation in decomposition processes, to search for patterns on seasonal and inter-annual time scale and to infer the relevance of the main environmental features (physical and chemical) on decomposition dynamic. During the three years of analysis, decay rates (k) ranges were 0.0066-0.0075 days −1 in autumn, 0.0108-0.0158 days −1 in spring and k = 0.0168 days −1 in summer. Average mass loss per day % range was 0.97-1.31% in autumn, 1.12-2.04% in spring and 1.79-2.06% in summer. A well-defined seasonal cycle was observed through the study years as result of the drought-reflooding dynamic and the highest percentage (91.1%) of the average mass loss per day % variability was explained above all by rainfall, temperature and conductivity.

Les zones humides sont parmi les écosystèmes les plus productifs, dont les roselières à Phragmites australis constituent un système basé essentiellement sur les détritus, où la décomposition de la litière représente un processus fondamental. Cette étude analyse un ensemble pluriannuel de données qui décrit les tendances cycliques relatives à la décomposition de Phragmites australis dans un milieu temporaire d'eau douce sujet à la gestion. Pendant trois ans, 45 jours d'expériences sur le terrain ont été effectués de façon saisonnière, en utilisant la technique du sac de feuilles dans un grand étang temporaire géré (Réserve Naturelle de l'embouchure de la rivière Isonzo, Italie du Nord), afin d'analyser les variations spatiales et temporelles dans les processus de décomposition, à la recherche de modèles à l'échelle temporelle saisonnière et inter-annuelle et d'en déduire la pertinence des principales caractéristiques environnementales (physiques et chimiques) sur la dynamique de la décomposition. Au cours des trois années d'analyse, les taux de décomposition (k) étaient 0,0066-0,0075 jours −1 à l'automne, 0,0108-0,0158 jours −1 au printemps et k = 0,0168 jours −1 en été. La perte moyenne de masse par jour était de 0,97 à 1,31 % en automne, 01,12 à 02,04 % au printemps et de 1,79 à 2,06 % en été. Un cycle saisonnier bien défini a été observé au cours des années d'études résultant de l'alternance assec-mise en eau. Le pourcentage le plus élevé (...

<p>Climate awareness is the starting point for understanding how climate change triggers and contributes to the climate crisis. A public that is aware is made up of citizens who are able to manage the best way to learn about the climate system and its changes and to understand how climate interacts with the individual and collective sphere of each person. Climate awareness provides everything citizens need to play an active role in addressing the negative impacts of climate change on people's lives, seize opportunities and be conscious actors in the present we are living and the future we shape for younger generations. Given the multidisciplinary, cross-cutting and all-comprehensive dimension of the interaction between climate and socio-economic systems (both on a local and global scale), improving Climate awareness requires more than just making reliable information and data available. There is an urgent need for strategic perspectives, critical thinking, and innovative outreach platforms and tools. </p> <p>To answer this challenge, the CMCC is implementing an outreach and communication strategy that addresses the complexity of the issue by implementing a multi-platform approach to climate literacy. The target audiences for this approach are as diverse as many social actors are involved in the process of improving their own climate literacy and, thus, contribute to the spread of more advanced climate awareness. These include public opinion as a whole, but specific initiatives and languages should be used to target specific audiences, such as students, journalists, policymakers, and civil society. Thus, the CMCC multi-platform approach addresses the climate crisis in the relationships between target audiences and media in their cultural, social, historical, economic and technological contexts. We present a series of concrete and ongoing initiatives that make up an integrated climate literacy strategy combining storytelling of climate impacts and adaptation solutions, the journalistic vision of a magazine, visual storytelling, podcast, art/science dialogue, science/communication collaboration about IPCC reports and the building of a community/network of climate communication initiatives through a climate communication international award.</p>
