6 Main GOALs and aims Budapest Green Infrastructure Concept has been based on a complex set of scientific analyses of environmental, ecological, social and economical aspects aims to set up development goals for strategy and action plan for a liveable, sustainable city defines the way for Budapest to win the green city image

7 Development of Green infrastructure concept of budapest A n t e c e d e n t s D a t a s u p p l y C O M P L E X A N D D E TA I L E D A N A LY S E S Ecologic aspects Green network Social; Recreation Economic aspects Laws, Regulations S y n t h e s i s o f a n a l y s e s SWOT Value Map Conflicts Map Approved by the Budapest Assembly in 2017 Vision of the future Horizontal objectives C O N C E P T Pillars Objectives Instruments M E D I U M - T E R M S T R AT E G Y Green infrastructure development and maintaining action plan I M P L E M E N TAT I O N

8 Changes in green area intensity ( ), long term trends Green area intensity ,9 % ,2 % ,5 % ,5 % Change of green area intensity Significant decrease (>25%) Decrease (10-25%) No change Increase (10-25%) Significant increase (>25%) Change of green area intensity in brownfields as result of a spontanious, uncontrolled greening Zone system of Budapest Buda hills, Periurban Danube corrodor, Transition and Inner zone

9 A set of new research questions! Surface heat measurement and mapping (2016) Institutional Tree alleys and green corridors Residential Greean area Other Waterfront green corridors Institutions with largegreen surfaces Fields Wetland Agricultural Forest The average green area intensity and surface temperature of green infrastructure elements Extra mortality Budapest, district level, extreme heat wave July

10 Green area (public parks and gardens) supply Urban public green area supply per capita Forest and green area Distance between forest and green areas and residential areas (m) Urban park Public park Public garden Average: 6m 2 /capita WHO proposal: 9m 2 /capita Accessible green and woodland areas of residential areas

11 Economic Evaluation of urban Green infrastructure Valuation method: V = A x B x C V = value of green infrastructure Value of green infrastructure elements A = basic ecosystem supply (Ft/m 2 ) (on detailed site survey of GI types, sub-types and sample areas) B = increase of value on ecosystem service of special areas (defined in urban plans and regulations) protected landscapes and nature conservation area area of cultural heritage importance listed, valuable cityscape, landscape, streetscape areas of environmental importance areas of urban ecological importance importance of recreation C = index of green intensity (weigh factor)

12 OBJECTIVES Objectives PILLARS HORIZONTAL OBJECTIVES AND PRINCIPLES CHALLENGES ECONOMIC SPATIAL STRUCTURAL SOCIAL ECOLOGICAL - Shortage of fundings - Shortage of value-based management - Reservation problems - Effects of agglomeration and changes of demography - Shortage of positioning of green network development - Medical challenges - Low supplying of recreational areas - Shortage of environmental culture - Problems of cityscape - Climate change - City climate (urban heat island) - Shortage of environmental culture - The spreads of the invasive species - Loss of biodiversity l i v e a b i l i t y s u s t a i n a b i l i t y e q u a l o p p o r t u n i t i e s Protection of green infrastructure Development of green infrastructure Management and regulations Reservation of the ration of the green and blue surfaces Protection and renewal of the trees and tree alleys Protection of the green areas and ensuring their primary functions Enhancement of the ration of the green and blue surfaces Afforestastion plan: new tree alleys and green corridors Revitalisation of creeks and development of their green network system Impoving maintenance standards of public green surfaces Creating more efficient organizational frame Enhancing cooperation between local communities, and municipalities Reservation and enhancement of the biodiversity of the natural and semi-natural areas Development of the green surface and nature reserved areas related databases and monitoring systems Raising awereness and improving the environmental culture Mutual green infrastructure development of Budapest and the agglomeration Brownfield area development as green spaces Eco-conscious rainwater managment supporting by green infrastructure development Strengthening the social role of economic stakeholders in green area managment Improving of designing methodology and technologies by using research achievements Improving green area supply Renewal of green areas Development of planning of green infrastructure and green network system

13 Protection and Development of Green network

14 Development of the Budapest green system Green Infrastructure Booklets Preventing of further builiding expansion Revitalisation of creeks and new linear green network and parkway Reserving whole green dominant areas Valueable areas for nature conservation Strengthen and improve Biodiversity Green connection between Budapest and agglomeration Reserving whole green dominant areas Improve the green connectivity to Agglomeration Planning and Communication Assistance Series
