USE OF ARBUSCULAR MYCORRHIZAL FUNGI IN LAND SCAPE RESTORATION
A short description of the NBS project
The reintroduction of lost ground microorganisms is a strategy strongly recognized as effective to promote the restoration of vegetation cover. Arbuscular mycorrhizal fungi (MA) represent an important component which is commonly lost as a direct result of the
activities of roads and railways constructions.
The main objective was the implementation of a more efficient soil erosion corrective revegetation measure in construction sites. The mycorrhizae fungi is specially recommended in degraded or poor grounds, or in those areas with restrictive weather conditions: aridity, salinity, scarce or torrential rains.
Firstly, mycorrhizaes favour plants rooting. Secondly the ground retention prevents landslides and in third place the mycorrhizae favour the continuity of the establishment of the vegetative cover with minimum contributions or no additional fertilizer and water.
NBS Implementation context
Description of the NBS
NBS Impacts scale
Urban density/ Soil consumption

Combined with other(s) environmental friendly solution(s)?
Project manager (leader and main partners): entities names, and know-how involved
Leader: Acciona Construcción (civil engineering works)
Main partners: Acciona I+d+i: Technology & innovation division & ADIF: manager of the cut slope plots for the tests
Who (else) was involved in the project ? (Inhabitants, local association, etc.)
Acciona Construcción: project manager
ADIF: Owners, co-owners of railway infrastructure
Public works Ministry : Client
More detail on the process and the role of the different stakeholders (How did it happen?)
The ADIF (High-speed railway lines manager company in Spain), in charge of managing a large part of the investment in rail infrastructures and of managing the high-speed network entrusted to its organisation, they offered their work sites to analyse the fuctionality of mycorrhizae amendments in slopes.
OPTIONAL Considering the actual impacts, who are the primary beneficiaries of the project.
Owners of civil infrastructures
and in general all the citizens
Adif, the Administrator of Railway Infrastructures, is a state-owned company that answers to the Public works ministry. This company has voluntary sustainable commitments contributing as much as possible to the preservation of the environment and 1.
Global Estimated cost of the project
20k€ - 50k€
Private Finance Initiative (PFI)
Description of the financing mechanism
Companies that relie on innovation to achieve more resilient and sustainable infrastructures .
Substitute with renewables and natural processes
Acciona Construcción wanted to test a corrective green solution based on natural solutions to solve erosion problems generated during their construction activities
Expected time for the NBS to be fully effective after its implementation
short (immediately to few months)
Expected life time of the intervention
more than 30
Already feedbacks on the project? In case, the project has already been adapted to new requisites, please explain the modifications brought
Success and limiting factors
Acciona Construcción wanted to test a corrective green solution based on natural solutions and at the same time to test a better cost-eficiency solution to solve the erosion problems generated during their construction activities
Looking for solutions with low economic impact on lower interest elements, to balance the costs of interventions with environmental value.
