Managing Transport Impacts in Asian Mega-Cities

Transcription

1 Managing Transport Impacts in Asian Mega-Cities Dr Tim Chatterton University of the West of England, Bristol, UK Monday 23 rd November IUAPPA Regional Workshop Tunis, North Africa Air Quality Management Resource Centre, UWE, Bristol

2 Quick Introduction Air Quality Management Resource Centre Major role in UK AQM process for 10 years International work: Bangkok AQ Action Plan CAI-Asia and BAQ (Asia) Workshops South African National Framework on AQ International researchers: Egypt, Nigeria(x2), Greece Institute for Sustainability, Health and Environment Links between 19 research groups Formally linking: climate change, environmental management, transport and land-use planning public health

3 Thanks to Cornie Huizenga: ADB (Partnership for Sustainable, Low Carbon Transport) The whole CAI-Asia team Better Air Quality Asia workshops

4 Not a simple topic Asian Mega-Cities are not all alike Transport is not all alike A range of different impacts: Air Quality Climate Change Social Justice Others, e.g. accidents, noise, physical activity

15 Differing Air Quality Management Capacity 2004 Benchmarking Air Quality Management in Asian Cities: Clean Air Initiative for Asian Cities(CAI-Asia) Air Pollution in Asian Megacities (APMA) Stockholm Environment Institute (SEI) Study of 23 cities in Asia comparing their capacity in: Air quality measurement Data assessment and availability Emissions estimates Management enabling capability

16 Huizenga et al.

17 Differences in Political Structures Degree of centralisation: Thailand: AQM originally dominated by national Pollution Control Department Indonesia: (Too much?) Decentralisation of responsibility to the provinces Role of judiciary: India: Intervention of Supreme Court with regard to transport in Delhi, and industry near Taj Mahal Involvement of civil society: Philippines: Reporting of Smoke-Belchers by mobile phone (SMS) 5 million signatures collected to force Clean Air Act

18 Some key issues Rapid growth of cities and poor urban planning Use of (shared) road space Mix of very wealthy and very poor Non-Motorised modes given lack of priority Not seen as progress Most who WALK don t have a SAY. Those who have a SAY don t WALK

24 Non-Transport Sources Transport emissions add to an often already high background concentration Considerable problems in many parts of Asia with regional particles Bangkok estimates of biomass related PM 10 range from 20 45% Much worse in Indonesia and Malaysia Dust from sandstorms can lead to levels of dust > 2000ug/m 3 Resuspension of dust from roads Atmospheric Brown Cloud

28 Cleaner fuels and cleaner vehicles Both essential (and closely linked) But: Some vehicles are just dirty e.g. 2-wheelers, old vehicles Problems with fuel adulteration Lack of a culture of servicing vehicles properly Problems with vehicle inspections Caution over use of metallic additives to increase octane (MMT, ferrocene)

38 The Future? India The People s Car Now You Can The world s cheapest car: $2,000 Less polluting than a 2-wheeler(?) but half the fuel economy. and takes up more road-space

39 The Future? China Production from 48,000 p/a in 1998 to about 20 million now Current estimated fleet: 100 million Range: km Actual max speed: km/hr Cost: US $ Scooter style electric bike (SSEB) Sources: Cherry and Weinert, 2009 CO 2 (g/pax-km) Car Bus Motorcycle Bicycle 4.70 BSEB SSEB Bicycle style electric bike (BSEB) but concerns about lead (C.Cherry, BAQ 2008)
