Elaboration d'une stratégie de gestion des délaissés
Short description of the intervention
In 2009, the city of Montpellier launched a large census project to valorize its abandoned areas. The study gives guidance on the management of abandoned areas in Montpellier, particularly in connection with environmental education and awareness objectives (Ref. 2). The strategy aims to preserve and promote the natural heritage of Montpellier; promote wastelands as reservoirs of biodiversity, tools for connecting natural spaces; protect and enhance the great green flows accompanying watercourses (biological links and privileged sites for fauna and flora); and develop a network of soft transport throughout the city based on the green network (rivers, agricultural, natural and park areas) (Ref. 4). "The spaces have been classified according to their context, their origin, their potential. This sometimes subjective typology presents a classification of the wasteland and makes it possible to take a particular look on each land. Surfaces of all shapes and sizes fall within this operational classification." Four Experimental projects include: Zenith Friche, Promenade of the Lironde, Pastourelle, Combemale" (Source: uploaded document).

Goals of the intervention
Goals included (Ref. 4):
-Preserve and promote the natural heritage of Montpellier
-Promote wastelands as reservoirs of biodiversity, tools for connecting natural spaces
-Protect and enhance the great green flows accompanying watercourses (biological links and privileged sites for fauna and flora)
-Develop a network of soft transport throughout the city based on the green network (rivers, agricultural, natural and park areas)
-Education and awareness-raising objectives, particularly with schools.(Ref. 1)
-These uncultivated spaces invite us to rethink the development of the territory, a number that completes the city's green corridor. (Ref. 1)

In connection to biodiversity preservation the following goals could be identified (Ref.2):
-In the climatic conditions of Montpellier it is of primary importance to allow rainwater to infiltrate to restore them to the ground and to limit the surface flows.
-Most of the abandoned spaces harbor an important vegetation, capable of absorbing part of the CO2 generated by the human activities and of rejecting oxygen.
-Vegetation also plays an important role in attenuating noise, and the network of wastelands contributes to the black framework of unlit urban spaces, a refuge for nocturnal animal species. (Uploaded document, page 4, "les eaux et les airs" section")

Implementation activities
- Late mowing to preserve biodiversity (Ref. 1)
- "Plans outlining possible actions provide a framework for developing green management initiatives in existing green spaces and future developments. These sheets were drawn up with the active participation of agents and field visits. An inventory of this type of action has been carried out on the study districts and must be extended to the entire municipal territory" (Ref. 4).

Impacts, benefits
Description of environmental benefits
Environmental quality:
-Improved air quality/carbon sequestration: Most of the abandoned spaces harbor an important vegetation, capable of absorbing part of the CO2 generated by the human activities and of rejecting oxygen (Uploaded document, page 4, "les eaux et les airs" section").
-Reduced noise exposure: -"Vegetation also plays an important role in attenuating noise, and the network of wastelands contributes to the black framework of unlit urban spaces, a refuge for nocturnal animal species." (Uploaded document, page 4, "les eaux et les airs"

Water management and blue areas:
-Increased protection against flooding/rainwater mgmt: -To avoid flooding by allowing the rainwater to infiltrate into the ground (Attached document)

Green space and habitat
-Increased conservation or restoration of ecosystems (local habitats for local species)/Restoration of derelict areas:quantitative figures not available, strategy recommends the optimal level of management for different typologies of abandoned spaces (Attached document).
-Reduction of biodiversity loss/pollination: qualitative description, "The abandoned generally host a biodiversity animal and vegetable higher than the rest of urban space. Protected from urban pressure (especially the notion of "cleanliness") wasteland are spaces of reproduction and propagation pioneer species. The presence of diversity spontaneous plant allows the development of many insects and birds that find refuge there and a source of food. Since we depend on diversity (through its potential use) then these territories must be regarded as treasures and not as simple abandoned places" (Attached document, page 4).
-open pollinated seed: wasteland are spaces of reproduction and propagation pioneer species. (Ref 4)

Comments and notes
Comments
2020 comments:
It is unclear if Coloco is still operating (Ref. 3) as of August 4, 2020.

Renaturalization of rivers and other water bodies was chosen in section two as many of the abandoned areas are along river banks (Attached document). The strategy for managing such spaces therefore contributes to renaturalization.
