Within few weeks, the 28th July Islamabad flood is a forgotten story but climate crisis is here to stay and its disasters are far from over. Recently published Sixth Assessment Report (AR6) of the United Nations Intergovernmental Panel on Climate Change (IPCC) has warned that world is going to face more climatic crises. Pakistan is among the top ten climate impacted countries and Islamabad is going to face more floods.

Real estate actors and regulatory authorities need to grab the departing message left by human screams and flowing cars during Islamabad flood. The message is clear that irregularities of urban planning must be fixed because the menace of climate change can convert them into deadly disasters.

The damages and intensity of Islamabad floods can be attributed to ecological distortions and climate change. The central piece of ecology is relationship and inter-linkages among all its components viz., water pathways, nullahs, green areas, landscape, trees, weather, animals and human beings. If our actions disturb one part of ecology, impact on other components is inescapable.

That’s what happened in the case of E-11, the worst hit area of Islamabad floods. As part of land development, original water pathway and nullah were distorted and narrowed down. Even houses were constructed on the nullah itself. The cloudburst induced flash floods exposed these ecological distortions in the form of a disaster. Cloudburst means very heavy rainfall in a short duration. Climate change has increased the intensity and frequency of cloudbursts.

A research report “Islamabad Pakistan Climate Change Vulnerability Assessment,” reveals that rainfalls have become highly unpredictable and in future the capital would face increased variability and frequent sessions of intense rainfalls leading to severe flooding.

The Capital Development Authority (CDA) has decided to check construction and bylaws in all housing societies. This is important because respecting, protecting and restoring urban ecology offer mitigation and adaptation mechanisms to develop resilience against climatic threats.

Rising temperature is another challenge for Islamabad. Historical data analysis in the report shows that since 1961-1990 the average temperature in Islamabad has increased by 3 Celsius and the future climate projections are nerve-racking. The temperature increase until 2039 is projected as 0.7 Celsius whereas until 2069 it is projected with an increase of 2.2 Celsius. Hence, ecological cooling mechanisms are crucial to minimize the impact of higher temperatures in Islamabad.

With the exception of rainy days, Islamabad residents have witnessed hotter days in June, July and even in August. A large number of men and youth with fewer women and children are commonly seen in the green belts around major highways such as Islamabad Expressway.

Dearth of parks, trees and green spaces inside many residential areas and housing societies compel citizens to nurse their green appetite in these green areas around highways. Surrounded by heavy traffic, people, particularly children, put their lives at risk due to contiguous, uncivilized and heavy duty traffic. Women, elderlies and disabled are unable to reach these green areas due to accessibility challenges. Prime Minister Imran Khan, in a cabinet meeting on 13th July 2021, had expressed concerns on the depleting green areas in Islamabad due to unplanned expansion of residential societies.

Green areas provide cooling impact in cities. Trees, parks and green areas are major component of urban ecology. These vegetative areas reflect back more sunlight compared to non-green and artificial surfaces. The lower level of heat absorption in green areas lead to cooler surfaces and reduced air temperatures.

Natural mechanisms of evaporation and transpiration in parks and green areas further add cooling impact against hot weather. Additionally these vegetative areas also absorb carbon dioxide from atmosphere.

CDA and relevant departments need to follow up with housing societies to ensure restoration of water pathways and development of parks and green areas according to their original commitments. In December 2019, Ms Zartaj Gul Wazir, the state minister for climate change had announced monitoring and ensuring development of parks in all housing societies . There is a dire need to follow up and implement the decision. Besides, government departments and real estate sector should integrate climate risk factors in their future plans.

In conclusion it is important to realise that if such climatic challenges are faced by Islamabad – one of the most planned cities – what would be the situation for other cities in the country? Therefore, provincial governments should prioritize climate risk assessments and subsequent plans for resilient cities.

  1. Very well explained. The government of Pakistan must take immediate actions in response to this situation before its too late.

  2. Dear Aftab Alam. You have established the issue very well indeed.

    I think there is a great mess b/w CDA and land revenue Authorities in Islamabad which creats flaws in matter of taking responsibility at the end.
    Rural lands are converted to urban localities under this mess without implementation of CDA Bylaws.

    Ultimately we find nobody to be held responsible. Departments and authorities blame each other and it ends up without any conclusions.

    As per my opinion Capital needs CDA, Land Revenue and MOCC at same page at once for beteer future.

  3. A really thought provoking article, congrats Aftab sb…it’s need of the hour to take climate change seriously..before it is too late, strict regulations shall be imposed especially with rexpect to new constructions so these meet all environmental standards, natural beauty of Islamabad is restored, and avoid these kind of devastations in future…

  4. Climate change is a topic world over today. The yesteryears people were oblivious of these facts.
    My commendations to crvoices and Aftab Alam Khan to bring about this topic and all his efforts for the scrutiny of government officials. More over educated people and private organizations should ponder into this fact and work jointly with the government.
    A good article Mr. Aftab Alam Khan. I wish you success in your endeavors.

  5. Dear Sir

    This so satisfying that you have presented the case in a convincing way. Hope authorities will also go through this piece.
