1) Gathering of evidence of the scale of the risk and vulnerability of society, and capacity of natural systems to lower the exposure.
2) Justification for & securing of city green ring & blue-green network, establishing of local spatial plans protecting ecosystem service donor areas.
3) Defining, dissemination, & adoption by the City the protocols for efficient engagement of blue-green infrastructure in building up the natural capital.
4) Identification of key components of ecosystem insurance system for the city, demonstration of real costs of business as usual in long-term, in comparison to ecosystem service -based management.
5) Development of economic tools and models to support decision making system.
6) Development of business models to establish public-private partnership in the area of building up natural capital and enhance regulatory ecosystem services in the city.
NATURE BASED SOLUTIONS & MEASURES
There are two important processes shaping the future of the City of Lodz: urban sprawl due to lack of coherent city strategy, proper regulations & spatial plans, & city interated revitalization programme.
The first process leads to decline of biodiversity, deterioration of water resources of the city (disappearance of rivers springs, drop of minimal flows in rivers, decrease of groundwater level & recharge), decrease of natural capital what results in: severe heatwaves and air pollution, pluvial flooding, poor water quality imposing risk to people and fauna.
The critical NBS are: LID; detection, delineation & restoration of river sources; re-establishing of wetlands; rebuilding of forest cover for microclimate regulation.
The revitalization programme is a EU co-funded effort of rebuilding the city centre with particular attention given to adaptation to climate change, transfer of ecosystem services from donor areas through blue-green system, & reestablishing of ecohydrological regulatory feedbacks bewteen biota & hydrology.
The critical NBS measures are: retention ponds and infiltration basins, tree trenches, infiltration ditches - in order to reinforce plant growth, microclimate regulation, groundwater & river recharge, green roofs, squares & street trees for climate regulation, flood protection & biodiversity stepping stones; bio filters and sedimentary ponds for improvement of water quality.

3. Enabling compact city - control of traffic, air & water pollution, preservation of cultural landscape & its educational values.
4. Linking water regulation with provisioning services of urban allotments & arable lands, biodiversity protection, fulfilment of EU species, water, nitrogen, hazardous substances directives.
5. Land use regulations towards LID due to the recognized role of ecosystem insurance value.
METHODS & DATA
1) Spatially explicite information about water related risks their costs, gray & green infrastructure maintenance costs;
2) Location of actual & potential blue-green infrastructure, its typology & type & load of ecosystem services;
3) Spatial plans & directions of city development;
4) Appreciation of BGI & nature based solutions linked to their protective role & capacities;
5) Institutional mechanisms available to recognize insurance value of ecosystems in management / spatial planning / property insurance / estate developement.
METHODS & DATA 1) Assewssment of natural capital - ENVI-based;
2) Valuation of regulatory services, and regulatory service mapping with relevance to BGI types - Qmethod & bluegreen factor;
3) Costs of avoidance & replacement related to delivery of ecosystem services;
4) Surveys on the optimal subsidy schemes to promote green infrastructure & ecosystem services;
5) Multiple criteria decision analysis for city development & management options;
6) Mapping of relevant policies & investment schemes.
MAIN OUTCOMES SOUGHT
• Map of risks & vulnerable areas;
• Tools to support legal system in protecting critical ecosystem services;
• Defined spatial planning & water management options with related ecological, economic & societal costs & benefits;
• Tools to reconsider local plans & the study of city spatial development;
• Ready-to-apply decision support tool for private-public partnership for incorporation ecosystem services into physical & financial insurance system;
• Tools to ammend city revitalization plans;
• Contribution to city climate adaptation strategy.
INSURANCE VALUE OF ECOSYSTEMS
• Not recognized in insurance system.
• Only conceptually recognized in sustainable management of city, risk management, economization of developement choices.
• NAIAD may trigger the discussion on the topic with key insurance companies: AVIVA, PZU, Generali, Warta.
• The physical influence of BGI and NBS on security of humans, nature & infrastructure has been considered for the project outcomes, its quantification & incorporation into management options.
• Thereby the main actors considered are city companies & departments, & SMEs.
