Nature Based Solutions, the first part of the handbook, proposing specific elements of nature-friendly solutions for adaptive vulnerability of cities.
Reducing the vulnerability of the capital city of Prague to the impacts of climate change in order to ensure a quality environment for the city’s inhabitants in the future.

Buildings are responsible for consuming about forty percent of all energy and are thus responsible for about one-third of greenhouse gas emissions.

The Czech Republic, as well as its capital Prague, has during the last decades been facing increasing frequency in extreme weather events related to climate change. Mean annual air temperatures have been increasing. In addition,frequency, intensity and duration of extremely hot periods (heat waves) will possibly be increasing in Prague. A risk of torrential rains and consequent local floods have also been increasing, as well as discharge fluctuation (droughts v. floods). It is expected that winter precipitation totals will increase: on the other hand, summer precipitation totals will be decreasing. In addition, number of days in the period without precipitation shall be significantly increasing as well as risks in an occurrence of droughts. The climate models predict an increase in extreme weather events (windstorms, tornados, etc.) frequency.
The Capital City of Prague Climate Change Adaptation Strategy is connected with the Strategy on Adaptation to Climate Change in the Czech Republic approved by the Government of the Czech Republic´s decision in 2015. It aims at reducing adverse climate change impacts trough nature-based solutions using natural vegetation patterns. The Adaptation Strategy also deals with conservation of water, soil and biological natural and landscape components and conservation and restoration of ecosystems resilient to climate change, thus contributing to natural disaster prevention. If nature-based solutions cannot be applied or are ineffective, suitable technological (also called grey) and soft measures, e.g. early warning systems or communication, education and public awareness/environmental education campaigns, will be used.The strategy tries to take into account specific Capital City of Prague´s patterns as the urban landscape, being characterized by high proportion of built-up areas, economic, technological and transport infrastructure high accumulation and unevenly dispersed vegetation komponent distribution.
By Prague Council Decision No. 3213 of December 12, 2015 and submitting an application, the Capital City of Prague became a Mayors Adapt Initiative, member, thus accepting a commitment to develop a climate change adaptation strategy and to monitor and assess the process and procedure of adaptation measures incl. risk assessment and elaborating biennial assessment reports. The Capital City of Prague Climate Change Adaptation Strategy shall be elaborated by the Implementation Plans Plans containing specific adaptation measures and pilot projects which contribute to climate chase mitigation, their monitoring and effectivity and effectiveness assessment.
From the analysis of the current state and projections of manifestations of climate change in the capital city of Prague until 2030 and the assessment of the vulnerability of Prague is the basis for the proposal of adaptation measures aimed at increasing the resilience of the city with specific goals.
