Les nouvelles Annales des ponts et chauss\u00e9es<\/em>, a magazine co-published with the Presses des Ponts, is placed under the scientific direction of a researcher and addresses a central theme of teaching and research at the \u00c9cole nationale des ponts et chauss\u00e9es (in French).<\/p>\n\n\n\n Understanding climate and hydrological dynamics, ways of dealing with risks and pollution, uses of this fragile resource, and new sustainable solutions: 23 contributions allow us to navigate through the many facets that the issue of water invites us to explore in a school of infrastructure and development such as ours, at a time when it is urgent to adapt our living environments to the present and future effects of the ecological crisis.<\/p>\n\n\n\n The global disruption to which the planet is exposed as a result of human activity has pushed us into a corner. In order to make life compatible with planetary boundaries, this issue examines possible paths for future socio-ecological futures. Technological innovation alone, and the idea of a decoupling between the intensity of human activities and their impact on the earth, will not be enough to make life compatible with planetary boundaries. Based on this observation, this issue of Transitions magazine considers that a major evolution in production and consumption systems is unavoidable. In fact, in the very short term, such is the alarming state of affairs. Climate, biodiversity, chemical contaminants, water resources: with their backs to the wall, the world of research and higher education is analyzing, examining and communicating possible paths for the socio-ecological future. Models, counter-views, territories, actions: four themes bring together 26 contributions from specialists at the crossroads of the humanities, social sciences and environmental sciences.<\/p>\n\n\n\n Simulation science on the one hand, and data science on the other, are the two facets of modern digital sciences. Based on modeling, mathematical analysis and the power of modern computers, they enable the analysis, prediction and even control of complex physical processes. They have established themselves as a third pillar of scientific research, complementing theoretical model development and experimental research. As a result, they have become indispensable to many scientific fields. The fields of research related to the ecological transition are no exception. The problems they raise are inherently complex. Multi-physical and difficult to calibrate, they involve numerous uncertain or random parameters, and can generate or rely on massive data. Interfaces with the human and social sciences are fundamental to determining the constraints of the underlying optimization questions. This new issue of Transitions examines the impact of data science and digital simulation on three of the major challenges characterizing the ecological transition: mobility and transport, climate and the environment, and energy production and supply.<\/p>\n\n\n\n In the face of the environmental emergency, it is imperative that the building and construction sector, which has a particularly high impact, launches its transition. Beyond the need for renovation, the act of building itself must be re-examined. What are the levers for action at the disposal of the sector\u2019s stakeholders? Systemic quantification, design optimization to save material, new building materials and processes, the adaptation of buildings to climate change, or circularity and reuse are all prospects to consider. <\/p>\n\n\n\n This latest edition of Transitions<\/em> examines the issue of transition at every step in the life cycle of a building. The question of a systematic approach is also raised, in addition to the implicit need for collaboration between all stakeholders. Experts, researchers and sector professionals, among others, share their research findings and feedback. Through a presentation of the overall state of play, this edition aims to contribute to a general reflection, be it collective or individual. <\/p>\n\n\n\n How should green finance be defined? What does the commitment to this new paradigm imply for companies, public authorities, and individuals? The 2021 edition of Transitions<\/em> provides answers to these questions. <\/p>\n\n\n\n The \u201cHistoire(s) de fonds\u201d collection aims to immerse you in the heritage collections of the \u00c9cole nationale des ponts et chauss\u00e9es: manuscripts, photographs, books, models, scientific instruments, engravings, and more, bear witness to a rich history of science and technology as well as public policies on land use and infrastructure.<\/em> Lighthouses, bridges, and other engineering structures… the \u201cmodel gallery,\u201d mainly composed of models of buildings constructed by civil engineers, was housed by the \u00c9cole nationale des ponts et chauss\u00e9es (National School of Civil Engineering) from its creation in 1747 until its demolition in 1954.The collections of this gallery-museum, now scattered or lost, showcased the grandeur of the engineers’ achievements, as well as the evolution of the techniques used in their construction. They also constituted a central educational resource in the teaching of the 18th and 19th centuries. The few traces that remain, some of which are gathered here, provide an overview of these tools, which were figurative, educational, and also artistic.<\/p>\n\n\n\n Eleonora Dallan and Auguste Gires, researchers in hydrometeorology, tell us about a common phenomenon that we all experience, one that is essential to our lives but ultimately little known: rain.<\/p>\n\n\n\n Throughout the book, structured like an imaginary walk, authors Eleonora and Auguste guide us to different \u201cstops\u201d focused on specific themes related to rain. Through situations that everyone may encounter in their daily lives, they aim to raise awareness of this phenomenon, decipher it, and better understand it and its immediate consequences. It is also an opportunity to revisit certain preconceived ideas and show rain in a new light!\u00a0(in French)<\/p>\n\n\n\n Eleonora Dallan and Auguste Gires, researchers in hydrometeorology, tell us about a common phenomenon that we all experience, one that is essential to our lives but ultimately little known: rain.<\/p>\n\n\n\n Throughout the book, structured like an imaginary walk, authors Eleonora and Auguste guide us to different \u201cstops\u201d focused on specific themes related to rain.

It traces the close relationship between city dwellers and their organic waste over several centuries, highlighting the variety of organizations and practices, and the difficulties encountered in achieving objectives that are regularly called into question.<\/p>\n\n\n\n The story takes us back to medieval Paris, where pigs and poultry feed on organic matter in the streets. Over the centuries, as urban development progressed, traffic problems, epidemics and the need to beautify the city led the authorities to gradually set up a public waste management service. In the 19th century, a wide range of processes for recycling urban organic matter fed agriculture, crafts and industry. This book invites us to discover – beyond the Prefect Poubelle’s famous garbage bin and the work of the ragpickers – the variety of inventions and practices of the period: Tournon’s garbage cover, Father Chapelier’s bread crust recycling processes, the production of luxury gloves from rat skins, and farmers’ enthusiasm for Parisian sludge. At a time when biowaste return-to-soil systems are enjoying a new lease of life, this journey back in time is intended as a contribution to today’s debates on the relationship between the city and the flows of organic matter that sustain its functioning.<\/p>\n\n\n\n This technical journey, the fruit of research carried out in partnership between Syctom and the \u00c9cole Nationale des Ponts et Chauss\u00e9es, is characterized by both its scientific rigor and its accessibility to the general public.<\/p>\n\n\n\n For the first time, this book traces the history of organic waste management in the Greater Paris area, from the Ancien R\u00e9gime to the present day, and presents a richly illustrated and educational account.

It allows us to envisage a paradigm shift by integrating the notions of sustainability over the long term into the strategies of financial and economic actors. From green bonds to European taxonomy, and including the multidisciplinary training of future transition actors, various aspects of the subject are discussed in Le Cahier des Ponts n\u00b05, by researchers, doctoral students, students, teachers and professionals from the \u00c9cole des Ponts community.<\/p>\n\n\n\n D\u2019ici 2050, pr\u00e8s des deux tiers de la population mondiale habitera en ville selon les Nations unies.

In order to make life compatible with planetary boundaries, this issue examines possible paths for future socio-ecological futures. Technological innovation alone, and the idea of a decoupling between the intensity of human activities and their impact on the earth, will not be enough to make life compatible with planetary boundaries. Based on this observation, this issue of Transitions magazine considers that a major evolution in production and consumption systems is unavoidable. In fact, in the very short term, such is the alarming state of affairs. Climate, biodiversity, chemical contaminants, water resources: with their backs to the wall, the world of research and higher education is analyzing, examining and communicating possible paths for the socio-ecological future. Models, counter-views, territories, actions: four themes bring together 26 contributions from specialists at the crossroads of the humanities, social sciences and environmental sciences.<\/p>\n\n\n\n Simulation science on the one hand, and data science on the other, are the two facets of modern digital sciences. Based on modeling, mathematical analysis and the power of modern computers, they enable the analysis, prediction and even control of complex physical processes. They have established themselves as a third pillar of scientific research, complementing theoretical model development and experimental research. As a result, they have become indispensable to many scientific fields. The fields of research related to the ecological transition are no exception. The problems they raise are inherently complex. Multi-physical and difficult to calibrate, they involve numerous uncertain or random parameters, and can generate or rely on massive data. Interfaces with the human and social sciences are fundamental to determining the constraints of the underlying optimization questions. This new issue of Transitions examines the impact of data science and digital simulation on three of the major challenges characterizing the ecological transition: mobility and transport, climate and the environment, and energy production and supply.<\/p>\n\n\n\n In the face of the environmental emergency, it is imperative that the building and construction sector, which has a particularly high impact, launches its transition. Beyond the need for renovation, the act of building itself must be re-examined. What are the levers for action at the disposal of the sector\u2019s stakeholders? Systemic quantification, design optimization to save material, new building materials and processes, the adaptation of buildings to climate change, or circularity and reuse are all prospects to consider. <\/p>\n\n\n\n This latest edition of Transitions<\/em> examines the issue of transition at every step in the life cycle of a building.
