Colombo becoming hotter making life more challenging
By Eng. Thushara Dissanayake
A few decades ago, many of those who lived in remote areas of the country might have viewed Colombo city as a paradise, where physical development, business, education and employment opportunities, etc., are concerned. Even the LTTE had used sceneries of Colombo city to brainwash their members during wartime, as there had been such a disparity between the North and Colombo. However, the beauty of Colombo has been tarnishing with time, due to many growing issues.
The city was a hotspot for terrorist attacks especially during wartime and any hope of peace was again lost with the attack that happened two years ago. Further, ever-increasing traffic congestion, air pollution, riverine flooding in areas adjacent to the Kelani river, frequent urban flooding, road closures due to protests, and epidemics like dengue are some other severe issues almost all the residents and working people therein are facing. We can hope that many of these issues will be
resolved to a satisfactory level by the ongoing and proposed infrastructure development projects in due course. However, unfortunately, emerging adverse phenomena like the heat island effect is making matters worse, and this article is about its implications.
Urban heat island effect (UHI)
Those who have been living or working in Colombo for a few decades would have experienced that the city is getting hotter and hotter. In fact, it is due to the combined effect of global warming and the urban heat island effect (UHI). An urban heat island occurs when a city experiences higher temperatures than nearby suburban areas.
An Australia-based engineering hydrologist, Brian Gunter, has studied the temperature variation in Colombo and the results, for the period 1940-2015, show that the average temperature has gone up by almost 1.5 degrees of Celsius. It is shocking that according to the current trend, the temperature will further increase in the future. Global warming caused by carbon dioxide and other greenhouse gases is a well-known phenomenon that does not need discussion herein. On the contrary, the heat island effect, which appeals equally important attention, is not widely discussed despite its severe consequences.
Substantiating the above findings Climate Risk Country Profile Report 2020, by the World Bank Group and the Asian Development Bank, on Sri Lanka states that Colombo temperature may have gone up by 1.6 Celsius due to the UHI effect and likely to damage the productivity of the service sector economy. According to the report, the damage will be done by directly impacting labour productivity and through extra costs for necessary adaptation.
Causes
There are many causes for the heat island effect and it occurs mainly due to the concentration of a large number of buildings and roads constructed out of concrete, asphalt, steel, and other heat absorbent materials. Waste energy from air conditioners, vehicles, industries, air pollution, and the absence of vegetation also contribute to the UHI effect. Not only daytime temperatures, but nighttime temperatures also increase due to the UHI effect. Different parts of the city may experience different temperatures creating many intra-urban heat islands and temperatures could be much higher than that measured in a general climatic station. The governing factor for such differences would be the uneven distribution of heat-absorbing infrastructure, human activities that generate heat, and the absence of natural landscapes that possess cooling ability.
Consequences
When cities become heat islands, the need for air conditioning to cool buildings goes up, in turn increasing the energy demand during peak hours while increasing the cost of energy. According to my knowledge, the future electricity demand of the country is forecasted based on the unmet demand together with the projected population increase. Therefore, the extra energy requirement owing to the UHI effect also has to be taken into account by energy sector planners, when calculating the future demand. As the urban population in Colombo is around 750,000 this kind of hidden electricity demand will be significant.
In the meantime, NASA has found that UHI increases rainfall rates around cities by 48 to 116 percent. Colombo already suffers from urban flooding during intense rains resulting in increased traffic congestion and a further increase in local rainfall may aggravate the situation.
Higher daytime temperatures caused by heat can cause heat-related deaths and heat-related illnesses such as general discomfort, respiratory difficulties, heat cramps, heat exhaustion, and non-fatal heat stroke. Therefore, those who are sensitive to heat and have to engage in outdoor activities are likely to be affected.
Mitigation measures
Trees, wetlands, and water bodies play an important role in controlling the heat island effect. Green infrastructure like parks, rain gardens, green roofs, and the likes also contribute significantly to mitigating the effect. Unfortunately, what we experience is a rapid decrease in such natural green areas, especially wetlands due to development activities, even though in 2018, Colombo was declared an international wetland city by Ramsar. According to experts, Colombo wetlands are shrinking at a rapid rate of 1.2 percent or 57 acres per annum.
Thus, the UHI effect in Colombo will more or less affect the quality of life of its dwellers and those who commute for work, education, business, and other necessities. The low-income population living in the city who cannot afford air-conditioning and those who are exposed to the outer environment will be most vulnerable. Therefore, the issue of UHI effect in Colombo will not merely be an environmental issue but a socio-economic issue as well.
As mentioned, the UHI effect is partly the result of global warming, a scenario we alone cannot control. However, we can manage factors that contribute to the UHI effect by first and foremost nurturing the existing green environment in Colombo. Other than that, only a few pragmatic options are available to mitigate the situation. Developing green roofs covered with plants, using lighter-coloured material for the outer surfaces of buildings, shading building surfaces with vegetation, and transforming every possible space to green spaces are some options that could modify the physical environment. In addition, the use of energy-efficient manufacturing technologies, vehicles, and equipment will also be helpful.

The challenge of keeping value-based politics alive
The current outbreak of anti-immigrant protests in Durban, South Africa is bound to have taken many a subscriber to value-based politics or political idealism quite by surprise. After all, this is evidence that despite the historic accomplishments of nation-builders of the stature of the late President Nelson Mandela it cannot be taken for granted that identity politics, including racism in its worst forms, is no more in South Africa.
At the time of this writing details are scarce on the substantive root causes of the protests but it could very well be that economic grievances, particularly on the part of the majority community in South Africa, are contributing considerably to the disaffection. Shrinking employment and material prospects are likely to figure majorly among the factors igniting the unrest.
Fortunately, the local authorities in Durban are losing no time in calling for peaceful co-existence among the relevant communities and are pointing to the vital importance of stepping-up national integration processes. Apparently, immigrants in sizable numbers from neighbouring countries are present in Durban. However, international TV footage of the protests quoted some local authorities as saying that the majority of the immigrants in some centres that housed them were not illegal migrants and had the documents that entitle them to be in Durban.
In the Durban protests the world has fresh proof of the socially divisive consequences of the gathering globe-wide economic disaffection, touched off particularly by the continuing crisis in West Asia. Going ahead, the world would need to brace for increasing identity-based unrest of the kind it is just witnessing in South Africa.
Considering that the material lot of ordinary people everywhere could only aggravate progressively, with the US and Iran showing no signs of negotiating an end to their confrontation any time soon, it will be left to the more democratic and progressive sections of the world community to initiate positive measures collectively to bring a measure of relief to the discontented.
The swiftness with which such relief will be provided would depend crucially on the importance those sections taking up these undertakings attach to value-based politics as opposed to Realpolitik of power politics.
Going by these yardsticks, Italy could be considered to be moving in the right direction. Recently Italy came to the fore in initiating the collective named, ‘Rome Coalition for Food Security and Access to Fertilizer’, which has as one of its aims the swift provision of fertilizer to economically weak African countries.
In a recent statement Italian Minister of Foreign Affairs and International Cooperation, Antonio Tajani, said that a principal aim of the project was to ensure that the farmers of Africa gained easy access to fertilizer, considering that food security is a growing concern among some of Africa’s economically vulnerable countries.
The statement went on to mention that some 30 countries hailing from the Mediterranean region, the Middle East, the Balkans as well as the FAO had been invited to join the coalition. The venture is far-seeing in that food security is main among the reasons for social discontent which in turn could degenerate into endemic political turmoil and bloodshed. Separatist violence and geographical fragmentation of countries wouldn’t be too far behind these developments, as Africa itself has often proved.
It is hoped that more G7 countries would take the cue from Italy and do what they could to ease the hardships of economically distressed countries, particularly of the global South. In these efforts they would need to break rank with the US, which is today brutally indifferent to the consequences of its policy of making ‘America First’, come what may.
Going by current developments, the Trump administration seems to be blithely oblivious to the wider, deleterious effects of its policy course in West Asia. Besides rendering Iran militarily and otherwise impotent nothing else seems to matter to Washington, as regards West Asia. This is policy short-sightedness of an extreme kind. After all, right now West Asia could be said to be sitting on the proverbial powder keg.
On the other hand, Iran is not giving the world the impression that it is doing anything constructive to get out of the policy straitjacket that it wove for itself decades ago. Rather than enter into a policy of ‘live and let live’ in relation to Israel in particular and initiate a process of reconciliation with the latter, it has chosen to operate within policy parameters that continue to damn Israel. This has put Israel always on the ‘defensive’ so to speak and prevented the opening up of space for meaningful dialogue.
That said, Israel is obliged to explore the possibilities of entering into a negotiatory process with the Arab-Islamic world that could lead to a de-escalation of tensions and bloodshed. It cannot continue to look at its neighbours through lenses that distort them as archetypal enemies who should be ‘wiped off completely from the face of the earth.’
In other words, the need is urgent for Realpolitik to give way to value-based politicks. Italy is beginning to prove that the latter approach could be pursued with some success. May be the EU and the UK could throw their weight behind these initiatives as well and establish that international politics could be refashioned on the basis of humane, civilized norms. The UN would need to be fully supportive of these moves and prove an organizational nucleus of the operations that follow.
In fact the time is ripe for people of conscience to collectively stand up on the side of peace and say ‘No’ to war and violence. Organizations such as the ICRC, the WHO and Medicines Sans Frontiers have already taken up this call. Referring to the widespread destruction of health facilities and their dehumanizing results these organizations have said, among other things, that ‘This is not a failure of the law. It is a failure of political will.’
True, ‘failure of political will’ among those powers that matter accounts for the runaway, uncontrollable nature of war and destruction in contemporary times, but more fundamentally it is a failure of the human conscience. It could very well be that the phenomenal levels to which violence and war have been unleashed today have had the effect of deadening consciences. This is a matter for urgent study and wide discussion.
