Climate change

Rehabilitation of wasteland in RT2012 and BBC
Fressin a réalisé depuis 2015 plusieurs actions visant à améliorer le bilan carbone et l’efficacité énergétique de la commune, tout en conservant la cohérence historique du centre-ville.
Ces démarches se sont concrétisées, entre autres, par la rénovation et réhabilitation de plusieurs bâtiments, la création d’un cheminement doux entre les bâtiments communaux de proximité et l’installation de panneaux photovoltaïques au sol pour une production et consommation d’énergie renouvelable et locale, l’installation de pompes à chaleur…
Ce projet fait partie des nominés de la 28ème édition des...
Since 2015, Fressin has carried out several actions aimed at improving the commune's carbon footprint and energy efficiency, while maintaining the historical coherence of the city centre.
 
These measures have been implemented, among other things, through the renovation and rehabilitation of a number of buildings, the creation of an easy pathway between local municipal buildings and the installation of photovoltaic panels on the ground for the production and consumption of renewable and local energy, the installation of heat pumps and so on.
 
This project is one of the nominees for the 28th edition of the Eco Action Trophies, the leading sustainable development competition for local communities, organised by the Les Eco Maires association.
Douala Sustainable City: Sustainable development and enhancement of the Makèpè-Missoké neighbourhood
Le projet Douala Ville Durable concerne l’aménagement du quartier Makèpè – Missoké, situé sur une ancienne décharge en zone inondable. La visée principale, définie dans la continuité du projet de drainage pluvial et en cohérence avec la politique de la ville, est de faire de Douala une ville durable et résiliente, tout en assurant son développement économique.
Dans cette perspective, un projet de restructuration et de valorisation de la zone humide et de lutte contre la pauvreté a été mis en œuvre par la Communauté Urbaine de Douala. Les efforts déployés pour préserver les espaces verts et les ressources naturelles ont...
The Douala Ville Durable project concerns the development of the Makèpè - Missoké neighbourhood, located on a former landfill site in a floodplain area.
The main objective, defined in the continuity of the rainwater drainage project and in line with the city's policy, is to make Douala a sustainable and resilient city while ensuring its economic development.
With this in mind, a project to restructure and enhance the wetland and combat poverty has been implemented by the Douala Urban Community.
 
Efforts to preserve green spaces and natural resources are thus aimed at transforming this floodplain into an asset for the development of the neighbourhood:
- on the one hand, by making the site a "green lung" to combat heat islands,
- on the other hand, by generating economic activities such as market gardening, recycling or even home renovation.
 
This project was designed to be replicable: a piece work of capitalising on knowledge and experience is therefore planned to disseminate it on similar sites successfully.
Cities change the world
Selon les Nations unies, près des deux-tiers de la population mondiale habiteront en zone urbaine d’ici 2045. Aujourd’hui estimés à 4,2 milliards, les citadins devraient être 5 milliards en 2030 et 6,7 milliards en 2050.

Au cœur des flux financiers et migratoires mondiaux, les métropoles façonnent les valeurs sociétales et les modes de vie planétaires. Elles sont les vitrines des mutations du monde, créatrices de richesses économiques et d’innovations technologiques.

Depuis le début du III ème millénaire, leurs centres se régénèrent et se densifient, tandis que les périphéries s’...
According to the United Nations, nearly two-thirds of the world's population will live in urban areas by 2045. Today estimated at 4.2 billion, urban dwellers are expected to number 5 billion in 2030 and 6.7 billion in 2050.

At the heart of global financial and migration flows, metropolises are shaping societal values and global ways of life. They are windows onto the changing world, creating economic wealth and technological innovations.

Since the beginning of the third millennium, their centres have been regenerating and becoming more dense, while their peripheries spread out. But their long-term development model is in question. Victims of their own successes, will metropolises eventually become unlivable? What will be the social and environmental sustainability of these urban complexes? How can we articulate attractiveness and quality of life for all?

From New York to Paris Ile-de-France, Tokyo to Copenhagen, Singapore to Medellin, metropolises are inventing, at all scales, new development paths to combine economic competitiveness, urban regeneration, social inclusion, energy frugality and climate resilience. And in doing so, they are changing the world.

This issue of Papers highlights particularly inspiring strategies and initiatives to address the fundamental challenges of (Very) Greater Paris.
Cooling our cities: what knowledge do we need?
La surchauffe des villes impacte le confort des citadins, et en période de canicule pose un enjeu de santé pour les populations sensibles. C'est pourquoi l'ADEME, soutient le développement de solutions de rafraichissement de la ville qui permettent d'améliorer le confort thermique estival, tout en adoptant une approche environnementale de l'urbanisme.
 
En 2017, l'ADEME souhaitait initier une réflexion scientifique et technique, en partenariat avec des acteurs externes, permettant de formaliser les résultats clés des travaux de recherche finis, mais surtout d'en avoir une lecture critique afin de dynamiser et...
Overheating of our cities impacts the comfort of city dwellers, and during heat waves poses a health issue for sensitive populations. This is why ADEME supports the development of city cooling solutions that improve thermal comfort in summer while adopting an environmental approach to urban planning.
 
In 2017, ADEME wanted to initiate scientific and technical reflection, in partnership with external stakeholders, to formalise the key results of the finished research, but above all to have a critical reading of it in order to energise and more deeply research these topics. Following a report on research in the field of urban cooling carried out by the City's Institute for Research in Science and Technology, a science and technology day was organised in Lyon on 27 June 2017. The day brought together more than 50 practitioners and researchers who exchanged views on urban cooling practices and knowledge.
 
The proceedings of this science and technology day combine a presentation on the state of the art on current knowledge and blind spots in research, the round table interventions that helped highlight operational issues and the work of participants who were invited to explore together, as part of a World Café, the barriers and research avenues that could contribute to ADEME's strategic research operations in this subject.
Recommendations for resilient territories adapted to climate change
Ce document présente les grandes recommandations élaborées par les membres du Partenariat Français pour la Ville et les Territoires (PFVT), plateforme d’échanges et de valorisation de l’expertise des acteurs français de l’urbain à l’international. Ces documents sont préparés à l’occasion du Forum Urbain Mondial d’Abu Dhabi de février 2020 et du Sommet Afrique-France de juin 2020.

This document outlines key recommendations formulated by the members of the French Alliance for Cities and Territorial Development (PFVT), the platform for exchange and promotion of French expertise in urban development at the international level. These documents were prepared in the context of the World Urban Forum taking place in Abu Dhabi on February 2020 and the Africa-France Summit on June 2020.
 
Climate change is a reality that has become a major issue for our society. Faced with growing global urbanization, the intensive exploitation of natural resources and the frequency of extreme weather events, it is urgent to mobilize at all levels of our cities and organizations, to strengthen the resilience of territories and of populations living in them.
 
To that end, it is necessary to consider far-reaching changes of urban and economic models, and to involve all the actors of the territory, to cooperate in a dynamic of anticipation, management or reconstruction in the event of a crisis.
 
It is within this framework that the “Resilience and adaptation to climate change” working group was gathered, in order to reflect on tools and solutions to make our cities and territories more resilient, more inclusive and more sustainable.
Food and agriculture: recommendations for a sustainable and relocated food system

This document outlines key recommendations formulated by the members of the French Alliance for Cities and Territorial Development (PFVT), the platform for exchange and promotion of French expertise in urban development at the international level. These documents were prepared in the context of the World Urban Forum taking place in Abu Dhabi on February 2020 and the Africa-France Summit on June 2020.
 
 In a context where urbanization and population growth, the use of resources, the quality of air, water and soil are all factors that question the current food system, it seems necessary to consider production and consumption models more respectful of the environment and health. Acting on the food system therefore supposes developing a transversal reflection integrating economic, social, environmental, health, educational, as well as cultural or urban aspects.
 
Faced with a globalized food system, the alliance of territories and the mobilization of local authorities and all citizens are key conditions for the transition to a more sustainable food and agricultural model. However, to that end, agriculture and food issues need to be thoroughly rethought and transition strategies need to be implemented. It is with this in mind that the "Food and Agriculture" working group met, in order to make sustainable food a pivotal point in the development of territories by relying on the relocation of the food system.

food challenges
Manger est un plaisir et un art. L’Unesco ne s’y est pas trompée en classant en 2010 le repas gastronomique des Français au patrimoine culturel immatériel de l’humanité. Pour autant, s’alimenter en quantité et en qualité suffisantes reste un défi majeur pour les métropoles. Selon les Nations unies, les citadins représenteront près des deux tiers de la population mondiale dans vingt-cinq ans. Le modèle alimentaire urbain doit inventer de nouvelles façons de produire, transporter et s’organiser pour répondre aux défis socio-économiques et environnementaux posés aux métropoles. Entre locavorisme et mondialisation, comment produire...
Eating is a pleasure and an art. Unesco made no mistake in classifying the French gastronomic meal as an intangible cultural heritage of humanity in 2010. However, food in sufficient quantity and quality remains a major challenge for metropolises. According to the United Nations, urban dwellers will account for nearly two-thirds of the world's population in 25 years. The urban food model must invent new ways of producing, transporting and organising to meet the socio-economic and environmental challenges facing metropolises. Between local supply and globalisation, how can we produce more and better with less?

From field to fork, the Papers of the Paris Region Institute give the floor to all the players in the food system. Researchers, academics, public and private decision-makers and civil society enrich, through their testimonies, the discussion to design another way to properly feed the urban individual in Ile-de-France and in metropolises around the world.
ArboClimat: the urban tree as a tool to combat climate change
L’arbre urbain est un formidable outil de lutte contre le changement climatique puisqu’il permet à la fois d’atténuer l’impact du volume d’émission de gaz à effet de serre des activités anthropiques de la ville, mais aussi de réduire l’effet de l’Îlot de Chaleur Urbain (ICU), voire de créer un Îlot de Fraîcheur Urbain (IFU). La Région Hauts de France et l’ADEME ont souhaité outiller les collectivités, les aménageurs, les gestionnaires de patrimoine arboré etles élus pour leur fournir un outil leur permettant de réaliser des scénarios de plantation et d’en évaluer l’impact sur la séquestration du carbone et sur le climat urbain...
The urban tree is a great tool to combat climate change as it both mitigates the impact of greenhouse gas emission from the city's anthropogenic activities, as well as reducing the effect of urban heat islands (UHIs), even creating urban cool islands (UCIs). The Hauts de France Region and ADEME wanted to equip communities, developers, tree heritage managers and elected officials to provide them with a tool to carry out planting scenarios and assess their impact on carbon sequestration and the urban climate.

This tool allows you to:

- Assess the impact of existing tree heritage,
- Understand the impact of a planting scenario on carbon storage and UHI control,
- Select species according to several indicators and not just the impact on carbon or UHI control.
Towards sustainable airport areas
Dans un contexte de mondialisation croissante des échanges, d’intensification des flux internationaux de marchandises et de personnes, et de hausse globale du trafic aérien qui en découle, les aéroports internationaux constituent des atouts stratégiques pour le développement et l’attractivité des pays et territoires qui les accueillent et qu’ils desservent. La présence d’une place aéroportuaire génère des interactions multiples, entrainant des externalités positives (retombées économiques en termes d’emplois, fiscalité locale, desserte en transports…) ou inversement négatives : pollution atmosphérique, nuisances sonores, congestion...
In a context of increasing globalisation of trade, increasing international flows of goods and people, and the resulting global increase in air traffic, international airports are strategic assets for the development and attractiveness of the countries and territories that host and serve them. International airports and their surrounding areas are of increasingly strategic importance for the development of the metropolitan regions they serve. They are also evolving and becoming distinctive economic and urban places in their own right. At the same time, airport activity has a significant impact on the surrounding environment and generates positive externalities such as economic spin-off in terms of employment opportunities, taxes paid from airport business, transport services, etc. or negative externalities such as air pollution, noise, traffic congestion or agricultural land consumption, etc. Airport areas therefore face many challenges of their own, which need to be addressed at this territorial scale.
 
The Institut Paris Region launched the « sustainable airports” initiative in 2015 with the support of the NGO Metropolis. Three workshops on this theme were organized between Paris and Atlanta. This report stems from this initiative. It is divided into seven thematic chapters, dealing with the major challenges for sustainable airports, making recommendations and highlighting good practices, basing itself on the collective work carried out by the workshops ‘participants and additional research led by the project team.
