The Department of Natural Resources and Ecology of the Voronezh region decided recently to organize a closed competition in order to develop a strategy for the future of the Voronezh Sea, a currently contaminated reservoir. The aim was to gather ideas on the use of the reservoir so it can be more attractive for the population and be a resource for the development of the city once the water is clean.

Today we are pleased to announce that our proposal has been awarded the first prize!

The proposal developed by Ecosistema Urbano after being selected for the second round of the competition works at different levels, addressing both the diverse sources of contamination and the potential uses of the existing reservoir. Our vision combines various solutions bringing new opportunities for leisure and activities for people to enjoy and experience the lake.

Our proposal

Addressing the different sources of pollution by providing customised solutions for each of them. These actions are framed as Phase 0. Among the actions we propose to place macrophytes on the surface of the water treatment plant tanks. This action can improve the performance of the Plant up to 40% and it is more efficient not only in the short term, but also in the long run as it reduces energy consumption and requires low maintenance.

Working with floating macrophytes which can absorb many different contaminants. They would be located in the shallowest areas of the lake to stop algae from blooming and emitting a specific smell that comes from the reservoir in summer.

Creation of bathing areas both in the urban and at the natural environment of the lake, incorporating the macrophytes as part of the water purification system.

A series of floating mobile cleaning infrastructures. These barges help to control water eutrophication as it is important to reduce the amount of phosphorus. They have tanks filled with alum for phosphor sedimentation at the bottom and incorporate various leisure programs and possibilities on the top, so they can be used in different areas of the city during the summer season. At the same time, these floating barges include sampling and analysing systems so that real time information about the water conditions and quality is made available for everyone through the web platforms and mobile app, specifically developed for this purpose.

Two areas are proposed to be developed through Public-Private Partnership. These new developments will help to shape a new identity for Voronezh and a new relationship of the city with the water.

The first is a mixed-use zone including housing, offices, retail, public and cultural buildings etc. This new development must be a pilot experience incorporating all the current sustainable technologies, as well as incorporating good practices in water management. Rainwater and surface water runoff is collected and purified through small ponds with floating macrophytes for being used afterwards for irrigation. Pump system for ponds and aeration fountains receive energy from micro wind turbines located on the shore.

As a second development opportunity, ecosistema urbano proposes turning the existing Pridachenskaya dam into a Leisure Island with different activities, becoming a new infrastructure for the city incorporating clean water areas available for swimming and bathing. The island also includes bicycle and jogging paths, boat station for water-sports, urban beach, gardens and parks, playgrounds and sport facilities.

Ecosistema urbano selected for the second round of the Voronezh Sea Closed Competition

Voronezh and the reservoir - image via prorus.net - click to visit source

Voronezh—which became popular in the late 80s because of a controversial UFO incident—is a city of over 1 million inhabitants, situated 500 km south of Moscow. It is located on the banks of the Voronezh River, which in 1972 was transformed into the Voronezh Reservoir or “the Voronezh Sea” as it is called by the inhabitants —a huge lake, 30 km long and 2 km wide. You can read more about the history of the reservoir here.

During the following decades the population enjoyed the cool water during the hot Voronezh summer, but in 1992 the authorities labelled it as “not fit for swimming” as a result of the increasingly polluted water.

The Department of Natural Resources and Ecology of the Voronezh region recently decided to organize a competition in order to develop a strategy for the future of the Voronezh Reservoir. The competition consists of two parts:

  • An Open Ideas competition meant to gather ideas that show the potential of the lake for urban and nature development.
  • A Closed Competition for teams of landscape architects, urbanists and ecologists that should combine ideas about possible future uses of the lake with technologies for cleaning it up. The strategy should include both a project and proposals for implementation.

We are glad to communicate that we have been selected among the four finalists of the closed competition. Over the following weeks we will be working hard on putting together a creative approach and a comprehensive strategy in a great presentation. More news soon!

LibreLigne | Urban acupuncture in Libreville, Gabon

Concept draft of the piers as urban catalyzers

Concept drawing of the piers as landmarks

Ecosistema Urbano was recently selected as one of the five finalists in a competition of ideas for the waterfront (Bord de Mer) of Libreville, capital city of Gabon. We were selected by the committee of the Agence Nationale de Grand Travaux du Gabon among many other proposals. In their own words, the proposal “has strong linkages to existing urban systems, improves coastline’s connections and celebrates Libreville culture and history.” Here is a brief descripton of the project:

The main goal of our proposal is to reunite Libreville with the seashore, and extend the life of the city to the waterfront in some specific points. This would be achieved through operations of urban regeneration, adjusted to the existing and to the specific cultural, sociological and economical context. The proposal concentrates visual impact, identity and activity in five nodes, instead of spreading them too thin along the promenade.

Those five pier-like structures (jetées) are a great way of getting closer to the water, of having a unique view of the city and at the same time of providing space for programs that could work as catalysers of the urban life. They act as unique landmarks, breaking the regularity of the very long promenade and facilitating the orientation of citizens. These points of “urban acupuncture” would drag attention and pull the urban life of Libreville to the seashore, providing a new space for citizens to interact.

The locations and uses of the piers are defined in relation to the city: to its flows, to the activity of the closest neighbourhoods and to the most relevant uses, buildings or public spaces nearby. Following that close relation with the surroundings, each pier has a singular character defined by the size, the shape, the vegetation, the dominant colors and other design factors, but also by the specific set of activities that can be performed in them. This way, we have the pier of Nature, Education, Culture and Music, Local Identity and Water.

On the other hand, the linear promenade itself changes the configuration of its section depending, again, on the surroundings. Some key elements are defined in that section: the waterfront boulevard for (unavoidable) motorized traffic, a series of landscape markers (associated with energy production and visibilization), a coastal bike lane, a waterfront promenade, an urban appropriable fringe… This elements are combined, stretched or shrinked, generating diverse profiles and multiple areas of interest.

The crossings in front of the piers would be shared areas for pedestrian and motorists

Thus, while the promenade is kept simple, regular and clean, these structures act as landmarks, dividing the seafront in more aprehensible, walkable sections, and marking the coast like ‘signal fires’ or lighthouses: they provide visual clues to help the passer-by understand his exact location at a glance.

In addition, based on the rapidly rising mobile market penetration in Gabon, and as a bet on the potential of hyperlocalized digital networks for urban life, the proposal includes a digital application that would work as a geolocated and participatory cultural agenda for the waterfront, showcasing the activities along the line, attracting citizens and visitors, allowing them to search and follow events, and acting as a geographic map or guide.
