Narration
-
- If you look closely at the pattern of language the
question is "somehow" straightforward.
- When I use words "straight forward"
mean the reason for creating heat Islands are multidimensional which we
need to interlink through a command chain of the various factors of heat
Islands.
- The question is not about seeking the solution,
but, in fact, at the primary instance is asking only for the reason for creating the heat Islands.
- Second the playing field is at the world level,
so, we don't need to differentiate between our surroundings and at the
world level, as, reason and circumstances are the same.
- Why I am saying so because the word limit restricts
us to the general explanation, if, the same question has been
asked in the essay writing then there could be a peculiar example
that differentiates the outcomes at the world level, and, with respect of
India, at the local level.
- Third, we need to drive the answer approach in the context of the habitat.
Structure of Answer-
1. Introduction- with one effective fact and definition
of heat Island
2. Reasons, in a cause-and-effect relationship, for creating
heat islands habitat.
3. One substantial point of final understanding.
4. Futuristic conclusion.
Answer-
- By the year 2050 68% world's population
will be urbanised, which, concerning India would be 50%
means urbanisation is an indispensable development of the future, now, it
depends upon us whether it will yield a "net positive" or
"net negative" results.
- In geographical terms Island is a land portion,
that is surrounded by water bodies, so, if, we put heat Island it means, "an area which is comparatively warmer surrounded by an average
temperature." Now, if the environment is the composition of 03 components-
nature, human-made, and human- heat Islands are part of the human-made environment which is primarily driven by the "unplanned-&- irrational
anthropogenic process" of urbanisation.
Causes of
heat island formation-
1. It starts with deforestation by clearing and levelling
the land, causing less transpiration results to less cloud formation, so less
precipitation that means higher rate of evaporation with consequences dry area
& higher amount of absorbing insulation.
2. The present-day building material such as cement,
asphalt, bricks, glass, steel and dark paint are having high insolation capacity, along with it, high rise building that means over per-unit-area we
have a "multiple unit area insulation", along with irrational amount
of albedo.
3. Now higher heat needs coolant so we use cooler,
fridge, air conditioner etc. means creating more power supply demand
that is more burning of fossil creating endless multiple channel of cause
-&- effect relationship.
4. We are producing more and more waste heat, through industrialised activities, another reason for creating access heat.
Heat land habitat is mainly phenomena of warm night happenings because the high amount of receiving insolation cause "long duration terrestrial radiation in night."
Heat islands surrounded by lower temperatures, now, when we look closely those are semi-urban and rural areas. If we follow the heat curve the semi-urban and rural
areas are closer to nature means urbanisation, which is the
future, but, if "society -&- state" does not create a nature-friendly environment ultimately we will pay the price. It is the society that needs to
lead, supplemented by the state through legislation(s), by changing its lifestyle so that urbanization is eco-friendly.
