Climate Change, Urban and Sustainability#

Project: SUSTAINABLE DEVELOPMENT PRACTICE GROUP FLAGSHIP REPORT ON MAKING CITIES GREEN, RESILIENT AND INCLUSIVE (P177249).

The activity will consist of the preparation of a Global Flagship report, the preliminary working title of which is Surviving to Thriving: Making Cities Green, Resilient, and Inclusive. In addition to synthesizing insights from existing literature, preparation of the report will be informed by background research aimed at filling key empirical knowledge gaps that will help to inform the report’s discussion of institutional reforms and policies for promoting green, resilient, and inclusive urban development.

The team are utilizing temperature and precipitation based index: SPEI, SPI, CDD, CWD, Number of annual hotdays and Annual mean temperature to support the analysis which organized into four inter-related workstreams:

  • Who is affected?

  • Stressor that make urban development less green.

  • Stressors that make urban development less resilient.

  • Stressors that make urban development less inclusive.

Some example are below:

Who is affected?

Which segments of city population are most exposed to climate-related stresses?

The analysis utilise CHELSA to generate heat hazard information number of annual hot days (a day with temperature above 35 degC), combined with FATHOM flood hazard to assess whether informal resident parcels (slums) coincide with hazard-prone areas in various cities:

  • BDI Bujumbura

  • BFA Ougadougou

  • CAR Bangui

  • GHA Accra

  • ETH Addis Ababa

  • ETH Diredawa

  • MLI Bamako

  • NER Niamey

  • TCD Ndjamena

  • ZWE Bulawayo

  • ZWE Harare

  • ZWE Mutare

  • IND Amritsar

  • IND Auraiya

  • IND Kanpur

  • LKA Colombo

  • LKA Kandy

  • TZA Dar es Salaam

  • VNM Ho Chi Minh

  • PHL Manila

  • AFG Jalalabad

  • AFG Kabul

  • PAK Karachi

  • MNG Ulaanbaatar

  • BRA Porto Alegre

  • HTI Cap Haitien

  • BIH Sarajevo

Stressors that make urban development less resilient

Urban resilience and weather shocks: a global nighttime lights analysis.

The study try to estimates short-term effects of different types of weather shocks on city economic activitiy using monthly TerraClimate data combined with high-resolution nighttime light monthly composites.

Some of the results, extreme weather shocks are challenging for all, whereas resilience to extreme dry shocks are widely across city characteristics.

Stressors that make urban development less inclusive

Is climate change slowing the urban escalator out of Poverty? Evidence from Indonesia and Latin America Countries (LAC).

Climatic variables that can help to measure dry and wet condition (SPEI) has been prepared at sub-district (admin3) level for Indonesia and LAC.

Example result from Indonesia: climatic shocks on urbanescalator.
