Alliance “municipalities for biodiversity”
The alliance “municipalities for biodiversity” was founded in 2012 as part of the German National Biodiversity Strategy.
3
Alliance “municipalities for biodiversity” The starting point and key objektive of the alliance is the implementation of the „Declaration on Biological Diversity in municipalities“. By signing this declaration, local authorities commit themselves to take measures for the preservation and promotion of biodiversity in their territories and within their means and to encourage government to appropriate actions. 260 German Municipalities have signed the Declaration.

Alliance “municipalities for biodiversity” Main fields of action of the „Declaration on Biological Diversity“ and the Alliance‘s main topics are:
• Green Spaces and Parks in urban settlement areas Urban concepts, ecological green space management, natural maintenance of green areas, preservation of natural areas, in densly populated urban surroundings, creation of nature experience spheres near the settlement zones, the use of indigenous and locally specific species, mitigation of the negative impacts of climate change on biodiversity, etc)
• Protection of species and habitats Networks of interlinked biotopes, species conservation programs, water conservation programmes
• Sustainability Tourism, watermanagement, agriculture, forestry
• Raising awareness for biodiversity and cooperation Promotion of civic engagement, environmental education, inter-municipal cooperation, networking
5
Alliance “municipalities for biodiversity” The alliance’s activies include • information exchange between network members, • networking, collection und publication of best-practice-examples und guidelines; • development of an internet platform; • organisation of workshops und congresses, • dissemination of the topic biodiversity in public and administration; • publication of brochures. • Joint implementation projects are also initiated and coordinated in cooperation with
other partners. • The alliance represents the interests of the member- municipalities in the European,
German and federal governments. • Current important topics are for example climate change adaptation, the
agricultural impact on biodiversity as well as that of forestry in municipal areas.

Alliance “municipalities for biodiversity”
“
Municipalities who want to join us, have to sign the “Declaration on biological diversity” and to bring about a decision of the city council to implement the declaration’s objectives. Furthermore a Membership fee has to be payed. The alliance “municipalities for biodiversity” has now 111 members throughout Germany.

Results of the IPCC-report 2014 The results of the IPCC- report show, that in spite of our efforts to reduce carbon and other greenhouse emissions climatic change is taking place and will accelerate significantly in the next decades. The impacts of this change show considerable regional differences and are very complex. The main aspects are •increase of the global mean temperature which a resulting shift of climate zones •climate-related extremes, such as heat waves, droughts, floods, heavy rainfall, cyclones, and forest fires •melting polar ice-caps, rising sea -levels and acidification of the oceans •increasing risks for human health, especially for people living in poverty, •increasing risks for terrestrial and marine ecosystems. Even in Germany the effects of climate change show considerable regional differences. It is therefore necessary to analyze the specific local risks and to develop regional and local climate adaptation strategies to protect the population from the unavoidable consequences of climate change.

23
Adaptation Policy in Germany In Germany, adaptation policy has been developed across all levels of government, with some adaptation and planning integrated into coastal and water management, into environmental protection and land use planning, and into disaster risk management. Even in Germany the effects of climate change show considerable regional differences. It is therefore necessary to analyze the specific local risks and to develop regional and local climate adaptation strategies to protect the population from the unavoidable consequences of climate change.
24
Adaptation Policy on the municipal level
On the municipal level some cities in Germany start to develop their own adaption strategies. One of the main instruments in this context is integrating climate change in land use planning and building design. In Germany, these tasks are assigned to the responsibility of the municipalities. Due to legal regulations the municipalities have to ensure by means of planning a sustainable urban development, which brings into harmony environmental protection and social and economic needs. Important aspects in this context are the protection of natural resources, climate change mitigation and - adaptation as well as healthy living and working conditions.
25
Adaptation Policy on the municipal level The Federal Government of Germany supports municipal climate mitigation and adaptation projects with funds. The City of Neuss has a long experience and expertise in integrating environmental aims into land use planning since the 1980ies and has successfully applied for these funds. Together with the University of Bochum and the Land of North-Rhine-Westphalia the environmental Office of the City of Neuss runs presently two research projects in the field of climate change adaptation.
26
Structure of the climate adaptation concept of the City of Neuss 1: Inventory: Climatic situation and local consequences of climate change 2: Vulnerability analysis 3: Identification and prioritization of impaired areas and persons affected 3: Creating a local action catalog basing on a overall strategy of mitigation 4 : Evaluation of measures and a controlling concept 5 : Stakeholder participation and concept for public relations
27
Structure of the climate adaptation concept of the City of Neuss 1: Inventory: Climatic situation and local consequences of climate change
Meteorological and air quality Measurements, thermal-scanner aerial surveys, calculations with complex meteorological computing models with the aim of
•Identification of regional and local wind systems and ventilation corridors
•Identification of hot-Spots which accumulate heat and pollutants during heatwaves
•Identifikation of areas with cooling potential
28

Local Action Cataloge for Land use Planning - Objectives to mitigate risks caused by high temperature •Cooling of residential areas during heat waves, especially in the evening
•No buildings and dense Vegetation (Wood) in corridors which are important for ventilation or areas near the hot spots which produce cold air in the evening
•Preserving green corridors between the settlement areas
•Planting of grassland in the ventilation corridors and areas near the hot spots to produce cold air
•Integrating the positive effects of the soil-cooling capacity and evaporation in the adaptation strategy (research projekt running)
33
Local Action Cataloge for Land use Planning - Objectives to mitigate risks caused by high temperature
•Fixing the identified Objectives in a planning reference map that is to be considered in all planning activities
•Optimization of planning by meteorological simulations

Considerable increase of the frequency of heavy rainfalls until the end of the century - the sewage and rain water channels of Neuss are not designed for theses rainfalls - risk of flooding of the basements and even ground-floors after heavy rain
Climatic situation and local consequences of climate change: Present and future Climate, Frequency of heavy rainfalls 2005 / 2100
43
Climatic situation and local consequences of climate change Present and future effects of the changing precipitation regime
Precipitation / rainfall: Increase of 30% in Winter, decrease of 30% in Summer

Local Action Cataloge for Land use Planning – Floods by rising ground-water level following heavy precipitation - Risk-Map
Areas with little distance of ground water from the surface – Blue: ground-water over the surface(wetlands),red: very little distance, Orange: little distance Higher demands on the protection of basements from intruding groundwater than in areas with a big distance between ground-water level and surface
45
Local Action Catalog for Land use Planning –Planning Objectives to mitigate Precipitation-risks due to overload of the channel system
Objectives and instruments: Decentralized retention of rain, infiltration on public and private lands by means of •infiltration basins /infiltration hollows •Ponds with plant beds •drainage trenches •Lawn, gravel lawns, •Grass pavers /Grass in the joints of pavement •Green Roofs
