Cities: a part of the problem, vulnerable to the impacts of climate change, a
part of the solution and even a solution to more than climate change
Cities need an integrated approach that considers mitigation, adaptation and
urban development

1) Cities: vulnerable to the impacts of climate change
• Extreme weather events damage buildings
and urban infrastructure
• Coastal cities affected by sea level rise
• Water resources stress: floods and
droughts
• Human Health – Heat and cold waves -
malaria; waterborne diseases; polluted
water
• Food Security – Livelihoods – Tourism
• Climate refugees move to urban slums
![Page 8: Climate Change and its Effects on Cities: An Overview from Development Cooperation Perspective](https://reader038.vdocuments.net/reader038/viewer/2022110323/56649d835503460f94a6a1e1/html5/thumbnails/8.jpg)
1) Cities: vulnerable to the impacts of climate change (Cont.)
• Heat–related diseases like heart attacks
and asthma
• Electricity shortages
• Government expenses (e.g., road
maintenance, emergency response)
• Animals and plants may become
stressed
• Rivers, lakes, and wetlands may
become more polluted
• Invasive species and pests may
become a bigger problem

1) Cities: A Part of the Solution
• Integration and building synergy between mitigation and adaptation on the city level has two complementary approaches• Improve Local Government operations• Set policies to change community’s habits
• Examples• Mitigation: promote energy efficiency, public transportation, solid management and &
recycling and renewables• Adaptation: promote green spaces, green buildings, rooftop farming and early warning
systems
Mitigation Adaptation

1) Cities: A Solution to More than Climate Change
• The co-benefits of climate protection
• save money
• reduce air pollution and traffic congestion
• improve public health and urban livability
• green the city
• boost local economic development
![Page 11: Climate Change and its Effects on Cities: An Overview from Development Cooperation Perspective](https://reader038.vdocuments.net/reader038/viewer/2022110323/56649d835503460f94a6a1e1/html5/thumbnails/11.jpg)
1) Cities need an integrated approach that considers mitigation, adaptation and urban development
The improvement of city services is related to the ability of cities to adapt to climate change and reduce their greenhouse gas emissions. Cities with excellent services are generally resilient cities:
• Advanced drainage systems can alleviate flooding during intense storms
• Healthcare services are equipped to respond to emergency situations
• Warning systems and transportation infrastructure allow citizens to evacuate in response to risk

2) International Initiatives of “Cities and Climate Change”
• GIZ assists its partners in identifying the wide range of causes of environmental risks. It implements climate policy guidelines through a wide range of practical measures in partner countries.
• UNEP ( Campaign on Cities and Climate Change)
• UN-HABITAT (UN-Habitat's Cities and Climate Change Initiative (CCCI))
• Cities Alliance (Supporting Cities in Addressing Climate Change Challenges: Enhancing Joint Work among Cities Alliance Members)
• Municipal associations such as C40, United Cities and Local Governments (UCLG) and ICLEI
• Rockefeller Foundation:(100RC) is dedicated to helping cities around the world become more resilient to the physical, social and economic challenges
![Page 13: Climate Change and its Effects on Cities: An Overview from Development Cooperation Perspective](https://reader038.vdocuments.net/reader038/viewer/2022110323/56649d835503460f94a6a1e1/html5/thumbnails/13.jpg)
2) Leading Cities, act on Climate Change
Example: Cities took part in Rockefeller 100 resilient cities initiative
Arab Region
• Ramallah: recent municipal projects, including residential postal codes, GPS navigation system and emergency response networks
Africa
• Dakar : working to address the effects of climate change and implement innovative solutions to address frequent water shortages and energy disruptions.
• Durban: exploring ways to adapt institutions, systems, and processes in order to facilitate integrated, innovative, and flexible planning
![Page 14: Climate Change and its Effects on Cities: An Overview from Development Cooperation Perspective](https://reader038.vdocuments.net/reader038/viewer/2022110323/56649d835503460f94a6a1e1/html5/thumbnails/14.jpg)
3) What’s about Egypt?
Aspects we have to think about…..
Anticipated Climate Change Impacts on Egypt and its urban
areas
Example: Climate change adaptation in informal urban
settlements
Types of adaptation measures under climate conditions of
Greater Cairo
![Page 15: Climate Change and its Effects on Cities: An Overview from Development Cooperation Perspective](https://reader038.vdocuments.net/reader038/viewer/2022110323/56649d835503460f94a6a1e1/html5/thumbnails/15.jpg)
3) Anticipated Climate Change Impacts on Egypt
Egypt's National Communications as well as many other national, regional and international reports and papers identified the following sectors as the main vulnerable sectors due to climate change impacts:
1. Coastal Zones
2. Water Resources
3. Agriculture sector
• Extreme Weather Events (flash floods, heat waves…etc., which does vary according to the geographical position) Nile Inflow
ChangesHotter & Drier
Weather
Sea Level Rise
Flash floods and SLR
![Page 16: Climate Change and its Effects on Cities: An Overview from Development Cooperation Perspective](https://reader038.vdocuments.net/reader038/viewer/2022110323/56649d835503460f94a6a1e1/html5/thumbnails/16.jpg)
3) Anticipated Climate Change Impacts on Egypt’s urban areas
Cities are affected by direct /indirect impacts
heat/cold waves (direct/ Indirect Impacts health conditions, food security, energy consumption, tourism and infrastructure)
SLR (Indirect impact/ food security)
Nile flow fluctuations (direct/ Indirect impacts/ health conditions and food security)
Most vulnerable groups: elder people, children, women, poor, people working in open areas
Most vulnerable areas: Informal settlements due to their physical conditions (exposure) + residents’ (un) preparedness (sensitivity)
![Page 17: Climate Change and its Effects on Cities: An Overview from Development Cooperation Perspective](https://reader038.vdocuments.net/reader038/viewer/2022110323/56649d835503460f94a6a1e1/html5/thumbnails/17.jpg)
3) Do Egyptian cities consider climate change?
• Good news: • Environmental profiles for each governorate is exist and done by EEAA• Cairo is partner with many cities around the world such as Frankfurt and
taking part in many international initiatives on climate change such as C40• Some efforts exist in Cairo and Alexandria cities such as studying SLR
impacts on Alexandria by different institutions and PDP initiative to study climate change impacts on urban informal areas in Cairo.
• Bad News:• We could not find information about the governorates visions for
environment, climate change or sustainable development on their websites or published reports.
• Benefits from cities partnerships are not clear yet.• Cities efforts are not collected in one inventory (NC could be the right place!)
Therefore, AB-CCC role is highly important!
![Page 18: Climate Change and its Effects on Cities: An Overview from Development Cooperation Perspective](https://reader038.vdocuments.net/reader038/viewer/2022110323/56649d835503460f94a6a1e1/html5/thumbnails/18.jpg)
3) Example: Climate change adaptation in informal urban settlements
GIZ/PDP approach as follows:
Assessing the areas’ exposure: analyzing climate data for past and future
Assessing the residents’ vulnerabilities and adaptive capacities; this includes collecting geographical and socioeconomic data
Raising awareness based on local findings and international knowledge
Implementing adaptation measures with participation of the community
Sharing knowledge & experiences with our partners (EEAA, IDSC, EMA, UUUs, etc.) such as Heat Early Warning Systems etc.

3) Example of adaptation measures: 1st pilot measure: Roof Top Garden/Farming
Expected benefits• Increased income generation• Enlarged food affordability and safety• Improved local air quality in the direct
surrounding of the plot• Cooled buildings by absorption of solar
radiation and shadowing• Establishment of private green areas• Awareness raising among local
population on environmental issues
Implementation• Cooperation with NGOs in Ezbet Elnasr• Residents’ eligibility (time, space, share
by 10% of the cost)• Trainings

3) Types of adaptation measures under climate conditions of Greater Cairo
• Awareness: Information campaigns related to impacts • Heat Wave Action Plan: Heat Wave Warning System • Urban agriculture: Rooftop Farming and/or Community Gardening
(open spaces) • Greening open spaces: planting campaigns • Climate-friendly energy: Wind/solar equipment tools • Green home retro-fitting: improved ventilation inside buildings and
isolation of housing • Green Economy & Finance: Green micro-insurance scheme for
covering risks provoked by climate change impacts• Adaptation measures concerning the impacts of climate change on
local economy and labor conditions
