TriOmix, the first creative sprint that reinvents waste sorting in the city
L’enjeu du tri sélectif en milieu urbain dense est connu : on trie deux fois moins en ville qu’à la campagne.
 
Face à ce constat, Citéo, en partenariat avec la Métropole de Lyon, son laboratoire d’innovation ERASME et l’Ecole Centrale, a organisé TriOmix : le tout premier sprint créatif dédié à l’amélioration du tri en ville.
 
Organisé à Lyon les 3, 4 et 5 juillet 2019, cet évènement a rassemblé associations locales, étudiants, designer, start-up, experts des déchets ou encore enseignants, pour travailler collectivement à des propositions d’amélioration de la pratique du...
The issue of selective waste sorting in dense urban areas is well known: we sort half as much in the city as in the countryside.
 
Faced with this fact, Citéo, in partnership with the Lyon Metropolis, its innovation laboratory ERASME and the Ecole Centrale, organised TriOmix: the first creative sprint dedicated to improving waste sorting in the city.
 
Organised in Lyon on 3, 4 and 5 July 2019, this event brought together local associations, students, designers, start-ups, waste experts and teachers, to work collectively on proposals to improve the practice of waste sorting, increase recycling and reduce waste production.
 
The fifty participants first underwent an immersion sequence, before taking their position on one of the challenges facing the Lyon Metropolis concerning selective sorting. The teams then proceeded to prototyping and then prepared their pitch for the opening of the premises to the public.
 
Six prototypes were ultimately unveiled and some of them are expected to enter an incubation phase in order to be tested in real-world conditions as early as 2020.
Gran Santo Domingo sustainable urban mobility plan
Mobilise Your City (MYC) est une initiative globale pour le climat qui promeut la planification intégrée de la mobilité urbaine ; elle vise à maximiser le potentiel de réduction des émissions des gaz à effet de serre (-50 % d’ici 2050), en particulier dans les villes des pays du Sud qui accueilleront la majeure partie de la croissance urbaine à venir.
 
Dans le cadre de cette initiative, le Grand Saint Domingue fait partie des 100 agglomérations qui se sont engagées à définir et mettre en œuvre un Plan de Mobilité Urbaine ambitieux. Cette initiative bénéficie de l’appui technique et financier de l’AFD  (...
Mobilise Your City (MYC) is a global climate initiative that promotes integrated urban mobility planning. It aims to maximise the potential to reduce greenhouse gas emissions (by 50% by 2050), particularly in cities in southern countries that will see most of the future urban growth.
As part of this initiative, Gran Santo Domingo is one of 100 cities that have committed to define and implement an ambitious Urban Mobility Plan. This initiative has the technical and financial support of AFD (French Development Agency) and the MYC programme.
The mission of the SYSTRA group was to support the national authority in charge of planning and improving mobility conditions in the region for 16 months.
This assistance consisted of:
 
- Providing technical support for the definition of an ambitious action plan,
- Developing digital planning tools,
- Building the capacity of local stakeholders,
- Setting up a participatory process that allows, during the study period, the setting up of real cooperation at the Gran Santo Domingo scale (INTRANT, municipalities, ministries, operators etc).
Study for the development of intelligent systems and digital solutions for sustainable urban mobility in Tunisia
SYSTRA réalise une étude stratégique et opérationnelle pour le développement de Systèmes Intelligents et de solutions numériques pour la mobilité urbaine durable en Tunisie « Smart Mobility Tunisie ».
 
La finalité de l’étude est de favoriser une transformation numérique en matière de mobilité qui aille dans le sens de l’intérêt collectif, de la durabilité des systèmes de transports urbains (c’est à dire des transports accessibles à tous, sûrs, économiquement efficients, performants écologiquement et non émissifs de gaz à effet de serre), et du développement d’un écosystème national de l’innovation...
SYSTRA is conducting a strategic and operational study for the development of Intelligent Systems and Digital Solutions for Sustainable Urban Mobility in Tunisia called "Smart Mobility Tunisia".
 
The aim of the study is to foster a digital transformation in mobility that works towards the collective interest, sustainability of urban transport systems (i.e. transport accessible to all, safe, economically efficient, environmentally efficient and not producing greenhouse gases), and the development of a national ecosystem of mobility innovation.

The scope of this study includes all-mode urban mobility, which includes individual urban modes of transport (car and motorised two-wheelers), collective (bus, light rail), active modes (classic cycling, walking), new urban mobility (autonomous vehicles, connected vehicles, etc) and shared urban mobility (self-service cycling, car sharing, carpooling, etc).
 
The expected results of the "Smart Mobility Tunisia" study are:
  • Analysis of the existing situation in Tunisia,
  • A benchmark of the world's existing smart mobility solutions,
  • Development of a strategy for Intelligent Systems and Digital Solutions for Sustainable Urban Mobility in Tunisia,
  • Establishment of a priority action plan for implementing the strategy,
  • Completion of feasibility and pre-operational studies for 2 or 3 selected projects.

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.

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.
