“Metabolism of cities” (Wolman, 1965)

• Quantify inputs, outputs, transformations and flows

• Traditionally three pressing metabolic challenges: water, pollution, sewage/waste

• Today fourth (more global)

metabolic challenge: CO2 / other greenhouse gasses Literature on urban metabolism

• Optimising metabolism of industrial systems through symbiosis industrial ecology

• Relationship humans - urban surroundings urban ecology

• Relationship human economies and natural ecosystems ecological economics

• Ecosystems as socially constructed: role of culture/politics political ecology

• Relation with production/trade between nations political economy

Common interests across disciplines • social and natural systems • city and hinterland • concern for sustainability in urban areas • concern for urban inequality Broto et al., 2012 Dynamics of urban metabolism

Direct resource use inside the city is only part of story, what about remote impacts?

Wachsmuth et al., 2016; Stanton et al., 2011 Lifestyles and lifestyle expressions

Lifestyles opinions and orientations  What people want to do

Lifestyle expressions Observable pattern of behaviour  what people want to do mediated by what they are able to do

Garden Concluding remarks

• Digitalisation may recraft lifestyles expressions of energy-intensive consumption and mobility practices, possibly even how such practises interlock, but there are important challenges

• Rebound effects

• Uneven access, digital divide, rural-urban divide, market-driven supply catering predominantly the well-off --> reinforced inequalities

• Scenario planning is useful, but acknowledge and communicate the uncertainty. Also, not just forecasting, also backcasting

[email protected] Implications for urban development

Hegemonic urban development strategy: densification (pros and cons) • Reduces distances which eases walking, cycling and health • Generates critical mass for public transport and hampers car use • Thus positive effects on daily mobility, but not on long distance (air) travel • Density supports collaborative consumption but mixed urban metabolism implications

Hegemonic urban development strategy: densification (pros and cons) • Reduces distances which eases walking, cycling and health • Generates critical mass for public transport and hampers car use • Thus positive effects on energy use for mobility, but not on long distance (air) travel • Density supports collaborative consumption but mixed urban metabolism implications

But it is about more than just mobility and other lifestyles... • Limited loss of valuable natural/agricultural land • Lower energy use in apartments, lower per capita building / infrastructure stock, • Yet also higher dependence on carbon-intensive building materials (e.g. concrete) • Concentration of people, jobs, activities, travel and resource use may lead to friction, negative externalities and pressure on wellbeing and health • Lack of access to nature and afforable housing may pressure wellbeing/health/equality - Social justice dimensions (Procedural, Recognition, Distributional) of digitalisation, urban transformation and decarbonisation need to be addressed and evaluated.
