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.
The regional food project of Caen Normandy Metropole
Le projet alimentaire territorial de Caen Normandie Métropole a été lancé en octobre 2017 ; pendant une année, une démarche participative impliquant tous les acteurs du territoire a permis d'élaborer des orientations stratégiques qui ont été reconnues par le label du Programme national de l'alimentation (PNA) en février 2019.
 
 Par l'organisation d'ateliers thématiques et de visites de terrain localement (ferme urbaine, marché de gros, association d'insertion par le maraîchage, agriculteur permettant la cueillette aux particuliers, cantines proposant des menus végétariens....), les acteurs du...
Caen Normandy Metropole’s regional food project was launched in October 2017. For one year, a participatory approach involving all the regional players led to the development of strategic guidelines that were recognised by the National Food Programme (NFP) label in February 2019.
 
By organising thematic workshops and field visits locally (urban farm, wholesale market, association providing work in market gardening, farmer allowing individuals to do their own picking, canteens offering vegetarian menus and so on), stakeholders in the Caen region now have a qualitative and quantitative regional food diagnostic and routemaps to promote short food circuits.
 
The challenge now lies in implementing this ambitious 14-action plan, aimed at bringing consumers and food producers closer together in six strategic areas:

I - Implementing metropolitan food governance;
II - Taking food into account in planning and land use;
III - Supporting the local economy (distribution platform, vegetable provision, urban compost etc);
IV - Strengthening collaboration and social bonding (sustainable food house);
V - Promoting local sourcing in communities;
VI - Communicating about local food identity and Normandy gastronomy, raising awareness, educating and training.

The FRUGAL (Urban Forms and Food Governance) action research programme run with the University of Caen between 2016 and 2020 is proving to be a quality methodological support to this innovative community approach to food: researchers present the results of their research to elected officials each year and the participatory methodologies of communities at all levels (city, urban community, metropolitan cluster) allow for new partnerships between researchers and stakeholders.
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!
Protecting Oshakati from heavy flooding during the rainy season
La ville d'Oshakati est l'une des plus grandes villes du nord de la Namibie et souffre régulièrement de fortes inondations pendant la saison des pluies.
 
En collaboration avec son partenaire IMDC, Tractebel a développé une solution durable afin de protéger Oshakati de ces inondations. Cette solution consiste en la construction d'une digue au nord-ouest de la ville ainsi que de ponts et d'écluses pour détourner et contrôler les eaux d'inondation venant de l'Angola autour de la ville. Au sommet de la digue, une partie de la future rocade sera modélisée en 3D et construite selon le plan directeur...
Oshakati is one of the largest cities in northern Namibia and regularly suffers from heavy flooding during the rainy season.
 
In collaboration with its partner IMDC, Tractebel has developed a sustainable solution to protect Oshakati from these floods. This solution involves constructing an embankment to the north-west of the city as well as bridges and locks to divert and control floodwaters coming from Angola around the city. At the top of the embankment, part of the future ring road will be modelled in 3D and built according to Oshakati's design master plan.
 
Key project issues include:
 
  • Defining the necessary measures to adapt community development to climate change, taking into account the relative urgency of the risks identified and available resources in collaboration with all local stakeholders;
  • Developing land use including better management of water resources: run-off, groundwater, rivers, estuaries, coastal waters and designing flood protection measures.

Lifou Island: roadmap to 100% renewable energy by 2020
L’objectif de ce projet est de réussir à substituer les 2.5 millions de litres de fioul utilisés actuellement pour la production électrique sur l’île de Lifou, en Nouvelle Calédonie par des énergies 100 % renouvelables d’ici à 2020, et faire ainsi de cette île une « vitrine » de la transition énergétique dans le Pacifique.
ENGIE a notamment conçu pour ce projet un schéma directeur énergétique permettant d’exploiter de manière optimale les ressources de l’île d’une part, et d’organiser le partage des services attendus entre la production (énergies renouvelables, gaz…) et le gestionnaire des réseaux d’autre part. Une étude...
This project sets out to successfully replace the 2.5 million litres of fuel oil currently used for electricity generation on the island of Lifou, New Caledonia, with 100% renewable energy by 2020, thus making the island a "showcase" for energy transition in the Pacific.
 
In particular, ENGIE has designed an energy master plan for this project to make the most of the island's resources on the one hand, and to organise the sharing of services expected between production (renewable energy, gas etc) and the network manager on the other.
 
A feasibility study and risk calculation were also carried out to ensure a local, sustainable and renewable energy network.
 
To achieve the target set, the island's energy mix will rely on the development of new capacity in solar (up 5.4 MW), wind (up 0.8 MW) and biofuel (up 1.2m litres), coupled with storage (5 MW).
 
The benefits of this project are threefold, allowing to:
 
  •  Strengthen the territory's energy self-sufficiency,
  • Reduce its carbon footprint,
  • Address intermittency and optimise the penetration of renewable energies within the island’s mix.
Study of the rehabilitation and improvement of Lake Zigh, Azerbaijan
Le concept du projet est de coupler la réhabilitation du lac Zigh, pollué depuis plusieurs années par le déversement d’eaux contaminées en provenance des zones industrielles avoisinantes, avec un développement urbain créateur de valeur dans la région de Baku, qui compte plus d’un million d’habitants.
Le but étant d’avoir une opération globale bénéficiaire, aussi bien pour l’environnement que pour l’économie.
D’importantes études préalables à l’opération de réhabilitation ont été menées par le groupe ENGIE :
- Collecte des données : rapports géologiques, topographiques, batimétriques, enquêtes...
The project’s concept is to couple the rehabilitation of Lake Zigh, which has been polluted for several years by the dumping of contaminated water from neighbouring industrial areas, with a value-creating urban development in the Baku region, which has a population of more than one million.
 
The aim is to have an operation that benefits everyone, in terms of both the environment and the economy.
 
Major pre-rehabilitation studies were carried out by the ENGIE group:
  • Data collection: geological, topographical and bathymetric reports, environmental surveys...
  • Basic design studies: hydrology, construction of sludge drying beds in the eastern zone, dredging the lake and channel and transporting sludge to the drying beds, construction of a cement-bentonite wall and preparation of the recovery area, construction of an urban park and a green belt around the lake...
  • Rehabilitation of the site is underway with technical solutions adapted to local know-how. They will be evaluated on the basis of international clean-up standards.
