Cities remains unique, universal and complex , invariably evolving, devolving, never finite and never defined. Cities create prosperity, poverty, employment, dichotomy and contradictions. Cities are said to be the future of humanity, but cities are also the reason for climate change, global warming , larger carbon footprints and rising temperature - making cities unsafe- both to the natural and manmade disasters. Making cities sustainable remains a challenge, opportunity, mirage and dream. Heading towards uncontrolled urbanisation, cities are pushing humanity into crisis- crisis of population, crisis of poverty and crisis of pollution. Cities remain anti-thesis to sustainability. Cities don't believe in inclusion and cities dies not treat majority of its inhabitants with respect and dignity -providing basic amenities of life to lead a dignified life. Making cities rational, humane, safe , inclusive, livable and sustainable will remain the greatest challenge on the planet earth.

6. Global Context of Cities

9. Cities and their Context
• Cities have been part of human history.
• - Cities- known to command power and authority
• Cities -- known for their dualities and contradictions.
• Cities- known for both -- positivities and negativities
• Cities -- known to be areas of concentration of population/ activities,
infrastructures, services, healthcare, education
• Cities -- known to be Engines of economic growth-70%
• Cities - generators of employment , wealth and prosperity,
• Cities – also known for their negativities,
• Cities – large consumers of resources/energy/ land
• Cities- generators of 70% waste;-- consume 60% global energy -
generating 70% of carbon footprints
• --98% /56% cities in low& middle/high income economies - do not meet
air quality WHO norms Cities- remain a manmade , mechanical habitat
• Cities- destroy natural habitat-anti-thesis to bio-diversity
• Cities- known to be creator of best/ worst living conditions
• cities – house both rich and poor

10. Cities and their Context
• Cities- home to large migrants
• Cities- home to slums
• Cities- remain in crisis- both -natural and manmade
• Crisis-- of population, poverty, pollution
• Cities – always evolving and devolving, never static/finite
• Cities – to dominate & define future growth/ development
• Cities- drivers/definers of nation’s future
• Cities - largely responsible for climate change ,global
warming, manmade disasters etc-
• However Cities - need rationalization
• Cities --need to be made – clean, green, nature friendly;
bio-diverse; productive, effective, efficient, humane,
• - inclusive, safe, Resilient ,sustainable, Healthy place to
live /work

31. Urban Heat Islands- Causes,
Effects
• “urban heat island” -- cities get much warmer than their surrounding rural
landscapes, particularly during summer.-- when cities’ unshaded roads / buildings gain
heat during day and radiate heat into surrounding air.
• urban core mid-afternoon temp. 15°F - 20°F warmer than surrounding, vegetated
areas.
• Causes
• Cities create their own microclimates -because they greatly alter local landscape.
• More Urbanization- more intensity of development- large/High Rise-
Buildings
• - Higher travel-- more cars
• -- Pattern of city planning, development
• Effects
• Higher Deaths--Centers for Disease Control and Prevention (CDC)
estimates --annual rate of heat-related deaths per 100,000 population is 0.3 in
large central metro areas –
• -increased health risk --of respiratory illnesses, heat exhaustion, heat
stroke, heat-related mortality.
• increase energy consumption- needed to air condition homes and

36. Urban Flooding
• Definition- Urban Flooding--Is the inundation of property in
a built environment, particularly in more densely populated
areas, caused by rain falling on increased amounts of
impervious surfaces and overwhelming the capacity of
drainage systems
• Reasons;
• High Intensity/prolonge Rainfall
• inadequate drainage
• Blocking the natural water channels or rivers;- human encroachments onto
the active flood channel
• Converting farmland, vegetation cover, and bare soil built-up areas.
• runs off from concrete structures- increase in impermeable surfaces and
urban development,
• Increase in changing climate/ Rising Temperature
• Location- coastal cities exposed to coastal floods
• poor flood management strategies,
• lack of flood early warning system disposal of solid waste in drainage lines.
