No climate scenario has been developed (the emissions scenarios and climate change from 4th AR, IPCC 2007 have been used)

The expected impacts of climate change are listed separately in the final report depending on the field of action of the specific adaptation measure.

For each of the analyzed adaptation measures the relevance and temporal urgency have been assessed. This clearly demonstrated that caused by their special relevance, their temporal characteristics and no-regrets characters, some measures are rather recommend for an early implementation, such as renaturation measures, soil conserving management, heat warning system, or the civil protection measures.

In order to find suitable adaptation measures for the assessment, the adaptation measures gained from the literature study were examined for their suitability for further analysis in a first step. The main problem is that there are no satisfying data for the majority of possible adaptation measures in Germany until now (missing workable valuation methods or fragmentary data). In order to make a meaningful assessment nevertheless, the limitation was therefore done using selected criteria.

The following adaptation measures have been analyzed in the different fields of action:

• Transport:
  new road surfaces;
  adaptation of the rail infrastructure to wider temperature ranges and heat;
  weather services in the transport sector;
• Spatial Planning:
  keeping free of fresh air corridors as an instrument of regional planning;
  green roofs;
  preventive planning for protection against floods and comparison with technical adaption options;
• Financial Sector:
  development of new insurance products respectively integration of new risks;
  cooperation solutions between state and insurance industry;
• Water Supply, Water Management, Coastal and Marine Protection:
  coastal protection by dyke increasing and beach nourishment;
  avoiding wastewater discharges to water by additional rain spillway basins;
  adapting the discharge quality of treatment plants to the reduced water conditions of water bodies;
• Building:
  avoid heat-related health risks by adapting the housing sector;
  protecting buildings from increased storms, heavy rain and wind;
• Industry:
  information for companies to adapt to climate change;
  avoid heat-related productivity losses by air conditioning;
• Health:
  heat alert system;
  cooling of hospitals;
• Soil:
  Soil-friendly conservation farming methods;
• Biological Diversity:
  design and management of nature reserves and their interlinking;
  restoration of floodplains;
• Agriculture:
  adapting the irrigation of agricultural land;
  use of appropriate plant varieties;
• Energy:
  design of power distribution network for extreme weather events;
  cooling of thermal power plants;
• Tourism:
  maintenance current tourism offers by preparing the slopes;
  diversification of the offers to enable summer tourism or all the year round;
• Civil Protection:
  education and training of civil protection organizations (civil protection exercises);
  revision of emergency plans.

For each of the considered adaptation measure, the interactions will be assessed and analysed to what extent the measures involved may have a beneficial or adverse influence on each other. The effects between adaptation measures will be evaluated and aggregated by a matrix. By considering such synergies and links but also overlaps and conflicts, measures bundle can be identified which are mutually dependent or act on different areas of activity simultaneously.
