Urban sprawl

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.
Industrial demonstrators for the sustainable city: Rêve de Scènes Urbaines
Le démonstrateur industriel pour la ville durable Rêve de Scènes urbaines, piloté par VINCI, Véolia et Artelia, propose une démarche originale de coopération entre les acteurs publics et privés de la ville pour expérimenter et produire des solutions urbaines innovantes. Il s’inscrit initialement dans un territoire en constante mutation, Plaine Commune, lui-même situé au cœur du Grand Paris.
 
Pour fonctionner, le démonstrateur s’appuie sur un écosystème ouvert, dont les objectifs sont de mettre en œuvre :
  • une plate-forme partenariale d’innovation urbaine,
  • un Living lab...
The industrial demonstrator for the sustainable city Rêve de Scènes Urbaines (Dream of Urban Scenes), led by VINCI, Véolia and Artelia, offers an original approach with cooperation between public and private stakeholders in the city to experiment and produce innovative urban solutions. It is initially part of a constantly changing region, Plaine Commune, itself located in the heart of Greater Paris.
 
To function, the demonstrator relies on an open ecosystem whose objectives are to implement:
  • a partnership platform for urban innovation,
  • a Living Lab of rebuilding the city on itself,
  • a showcase of the city's French know-how in the Plaine Commune region.
 
Every year, 150 ideas are collected and handed over to Plaine Commune. The region selects ideas that can help implement its strategic development plans.
The ideas and experiments produced as part of Rêve de Scènes Urbaines are intended for dissemination. In France, eight partner regions have joined the approach in order to benefit from ideas and to able to launch local experiments. The dynamics of the Rêve de Scènes Urbaines demonstrator can be increased thanks to the contribution of innovative companies from these regions.
 
Abroad, Rêve de Scènes Urbaines is part of the export efforts of the Strategic Sector Agreement "Industries for Construction", welcoming foreign delegations to France, and feeding local contacts of French companies with the association’s work.
300 participants at the 1st Free Transport City Meetings
Vous n’avez pas pu passer à côté : depuis le 1er septembre 2018, l’agglomération dunkerquoise est devenue la plus grande agglomération française à proposer un réseau de transports en commun entièrement gratuit à ses 200 000 habitants et à tous ses visiteurs. Dans la foulée, Dunkerque accueillait les premières Rencontres des villes du transport gratuit.
 
L’événement, le premier du genre en France, a attiré plus de 300 personnes – élus, techniciens, usagers, militants associatifs – venues des quatre coins du pays, voire de plus loin (Pologne, Allemagne, Estonie, Suisse, Brésil…).
...
You couldn't miss it: since 1 September 2018, the Dunkirk conurbation has become the largest French city to offer a completely free public transport network to its 200,000 inhabitants and all its visitors. In the process, Dunkirk hosted the first Free Transport City Meetings.
 
The event, the first of its kind in France, attracted more than 300 people - elected officials, experts, users, community activists - from all over the country, and even further afield (Poland, Germany, Estonia, Switzerland, Brazil...).
Invited to discover Dunkirk’s new bus network and the major urban developments carried out throughout the city, participants also attended roundtable discussions and expert presentations. A wonderful moment to reflect, question and exchange views before (perhaps) going free themselves.
Caen, nature city
A dix-huit kilomètres de la mer, à la confluence entre l’Orne et de l’Odon, Caen s’affirme comme une ville entre mer et nature.
Structurée par un fleuve côtier partiellement canalisé, la ville fut fortement marquée au nord par l’industrie métallurgique, tout en préservant au sud l’accès direct à la nature par sa vaste prairie inondable qui pénètre au cœur de la ville.
Aujourd’hui connue pour sa plaine agricole et la qualité de sa pierre calcaire, Caen puise en réalité son identité dans les cours d’eau et les prés normands, ce qui en fait une ville naturellement structurée par sa trame verte et bleue. Par sa...
Eighteen kilometres from the sea, at the confluence of the Orne and the Odon, Caen is most definitely a city between sea and nature.
Structured by a partially channelled coastal river, the city was heavily affected to the north by the metallurgical industry, while preserving to the south direct access to nature by its vast flood meadow that goes right into the heart of the city.
Today known for its agricultural plain and the quality of its limestone, Caen actually draws its identity from Normandy’s rivers and meadows, making it a city naturally structured by its green and blue corridors.
With its greenspace policy and its work to preserve ecological continuity, Caen has outpaced legal expectations for promoting biodiversity, nature and landscapes.
Energy transition and urban planning video: how to move towards sustainable cities?
Croiser les enjeux de l’environnement, du climat, de l’énergie et des réseaux avec les politiques de l’urbanisme, de la mobilité et de l’habitat est essentiel pour construire des projets de territoires durables. L’aménagement des territoires est le levier le plus efficace pour réussir la transition énergétique dans la mesure où il impacte directement la demande en énergie.
 
Il peut par exemple créer des villes dépendantes de la voiture et très minéralisées, ne permettant pas de réguler les températures, ou tout au contraire des villes économes et résilientes offrant un cadre de vie attractif à leurs...
Combining environmental, climate, energy and network issues with urban planning, mobility and housing policies is essential for building sustainable regional projects. Land use is the most effective lever for successful energy transition as it directly impacts energy demand.
For example, it can create car-dependent, highly concrete cities which do not regulate temperatures, or, on the contrary, economical, resilient cities offering an attractive living environment for their inhabitants.
Thus, a well-organised region, sufficiently dense which makes the most of its local resources, can at the same time reduce its energy needs, produce its own energy and adapt to the climate of the future. The urban planning code now offers opportunities that communities can seize on.
This video, produced by Agam and DREAL Provence Alpes-Côte d'Azur, in association with the region's technical services, is a relevant way of presenting legal levers and making them possible by local examples of successfully integrating the energy transition into urban planning. Elected officials, experts and planning stakeholders, it's up to us!

The Caen Peninsula urban project offers new perspectives to the area of Caen la Mer. Sustainable neighbourhoods, soft transport modes, river atmosphere, green environment, economic, cultural and sporting activities all promise an unrivalled environment and quality of life.
 
The municipalities of Caen, Mondeville and Hérouville Saint-Clair, the Caen la Mer Urban Community, the Normandy Region and the Normandy Ports Joint Union have been working together since 2010 to implement an ambitious urban renewal project on the site of the peninsula, which is structuring for the region.
 
The Caen Peninsula urban project covers an operational perimeter of 300 hectares. The member communities of the order group agreed in 2016 on the need to set up a Major Interest Project (MIP), a memorandum of understanding created by Law No. 2014-366 of 24 March 2014 for access to housing and renovated urban planning provided for under Articles L.350-1 to 7 of the Urban Planning Code. The content of the MIP identifies the four structuring urban development projects currently in progress or planned for the future whose aim is to renew the strategic sector of the peninsula in an ambitious and sustainable way:
 
- The Peninsula Point
- La Nouveau Basin joint development zone in Caen
- The Hérouville peninsula JDZ
- The Calix JDZ in Mondeville
New free transport network in Dunkirk: summary of key results
Depuis le 1er septembre 2018, la Communauté urbaine de Dunkerque est la plus grande agglomération européenne à offrir la gratuité du transport en commun 7 jours sur 7 pour tous les usagers.   Chacun peut l’utiliser à sa guise pour ses déplacements professionnels, universitaires ou personnels.
La nouvelle réorganisation du réseau DK’BUS Marine et l’ensemble des aménagements réalisés ont conforté le réseau de transport en commun dans sa fiabilité, fluidité et rapidité.
 
Doté de 5 lignes chrono (C1 à C5) passant toutes les 10 minutes à un arrêt et de 12 autres lignes, le réseau...
Since 1 September 2018, the Dunkirk Urban Community has been the largest European city to offer free public transport 7 days a week for all users. Everyone can use it as they please for their professional, academic or personal travel.
The new reorganisation of the DK'BUS Marine network and all the improvements carried out have improved the public transport network’s reliability, fluidity and speed.
 
With 5 timed lines (C1 to C5) running every 10 minutes at one stop and 12 other lines, the network also offers bus traffic between 5.30am and 10.30pm (Monday to Saturday). An additional service is provided on Fridays and Saturdays to provide late-night journeys to the outer limits of the region.
 
Buses have also become places of community and entertainment and are equipped with wifi and charging stations for mobile phones.
 
To assess the diversity of the effects of being free to use, the VIGS research association in partnership with the local urban planning agency (AGUR), with funding from the Urban Community, conducted an unprecedented in-depth study, both qualitative and quantitative, on the subject.
Improving sanitary conditions and preventing water-borne diseases in Burundi
Le projet couvre une commune en milieu péri-urbain : Mutimbuzi, province de Bujumbura rural au Burundi, à l'ouest de la capitale et proche de la frontière congolaise.

Il a pour but d’améliorer les conditions sanitaires des communautés visées et de réduire la propagation des maladies hydriques, telles que le choléra ou la diarrhée. Au-delà de la mise en place d’installations hydrauliques et sanitaires, un réel travail de sensibilisation/éducation comportementale a été développé selon une approche participative intégrale afin de garantir des améliorations à long terme.
 
Le...
The project covers a commune in a peri-urban area: Mutimbuzi, a province of rural Bujumbura in Burundi, west of the capital and close to the Congolese border.

It aims to improve the sanitary conditions of the target communities and reduce the spread of water-borne diseases such as cholera and diarrhoea. Beyond the establishment of hydraulic and sanitary facilities, real work on awareness raising/behavioural education has been developed using a comprehensive participatory approach to ensure long-term improvements.
 
The project has set up the following actions:

- Introduction of a participatory methodology called WAST that raises awareness and provides training in waste management and the right to water, hygiene and sanitation,

- Structuring, legal training and empowerment of the community through the creation and training of Hygiene and Sanitation Committees (HSCs) capable of taking charge, monitoring and evaluating a sanitation service throughout the sector, from construction of infrastructure to the recovery of collected waste (Ecosan latrines),

- Supporting and empowering the municipality through the strengthening of its capacities (awareness-raising and maintenance of works), implementation of communal regulations, the strengthening of synergies with other local, regional and national policies, and the establishment of criteria to respect the right to water and sanitation,

- Ex ante evaluation of innovation in health impacts (village surveys and health centres).
