Meeting the Climate Change Challenge with an Integrated Approach. Urban Visions and Challenges Seminar

Transcription

1 Cities cover 2% av world land areas but contribute to 67% of global energy use and 7% av global energirelated CO 2 emissions (OECD 20) Meeting the Climate Change Challenge with an Integrated Approach Urban Visions and Challenges Seminar Lund University Urban Arena Dr. Ulf Ranhagen Professor/Architect Honorary Professor, Tongji University in Shanghai Surprise Dilemma 99/ The relationship between the climate change issue and urbanization has been observed by UN Habitat but it has mainly been considered as an technical and economic issue not related to spatial planning Important factors for climate change mitigation and adaptation Political visions and actions Economic instruments carbon dioxide taxes energy tax relief on renewables etc Social justice and life styles Triple helix collaboration Integrated urban &rural planning and design

2 The SymbioCity Initiative is an overarching concept and communication platform for Swedish institutions and actors involved in sustainable urban development in an international context Symbio City Approach main objectives capacity building by mutual sharing of knowledge and experience multi- och transdisciplinary collaboration and dialogues city-wide strategies as well as integrated systems solutions guidelines for sustainability reviews The SymbioCity Approach can be used a a conceptual framework and guide for sustainable urban development The Symbio City Approach emphasises the spatial dimension which is important for any intervention to promote sustainability Source: Ranhagen U & Groth,K (202) Source: Ranhagen U & Groth,K (202) 2

3 The Conceptual model emphasises a number of key factors that should be adressed in sustainable urban development The SymbioCity Approach promotes urban review and planning processes that consider potential value-adding synergies between urban systems in a spatial and institutional context Source: Ranhagen U & Groth,K (202) Source: Ranhagen U & Groth,K (202) Urban density Attractive and liveable tools for analysing the experience of urban form Correlation between urban density and emissions in i 7 cities in OECD Edmonton Canada Source: OECD (202) Perceptual city reading

7 7 A Life Cycle Perspective is needed An INTEGRATED APPROACH reduces the ecological footprint and contributes to favorable economic and social impacts Sustainable cities an issue of responsibility for our and future generations We haven t inherited the world from our ancestors, we have borrowed it from our children and grandchildren Extra investments in planning and construction Increased property values due to attractiveness Avoid suboptimisation economic benefits Facilitate co-operation sharing of knowledge Energy (due to increasing oil prices) Environmental Health care Social Management, operation and maintenance -5 years ROI low energy buildings 0-5 years ROI waste water and waste THE ATTRACTIVE and CLIMATE SMART CITY Thank you for your attention!
