Today we are getting to discuss a really important topic for the civil services examination preparation, especially from the attitude of prelims and this subject has actually emerged together of the foremost important topic for the prelims examination. this subject is certainly small but its impact is vast, we are talking about Environment and Ecology for CSE.
Environment and Ecology (Analysis)
Now since 2011 when this subject was specifically mentioned the number of questions that are, they will be allocated to the present particular topic is really very high. In 2014 as many as 18 to twenty questions were there from this section only. the rationale for this is often very simple, Indian Forest Services examination prelims process was introduced therein examination and therefore the prelims process is essentially merged with the Civil Services examination. So, once you appear for the Civil Services examination a number of you furthermore may appear for the Indian Forest Services prelims examination.
Now, since the paper is the same a load of Environmental Ecology topic has gone up which is why this has become a crucial portion of the paper. we will basically see that in 2015 the number of questions was around 11 to 12 but from this small topic/chapter is really very significant. So, now we'll attempt to identify that How and Why you ought to study Environment & Ecology so on cover most of the items that you simply want to try to for scoring 80 to 90 percent marks within the questions from these sections.
First and foremost you would like to know that Environmental Ecology may be a subject which is a combination of three different subjects and that they are independent too. An interdisciplinary approach that includes:
Biology
Ecology and
Geography
Since the approach is inter-disciplinary in nature repeatedly we discover the questions also are on the margin of various subjects. for instance, if we mention Ecology & Environment we'll be focussing on biosphere, biology, Animalia, or Plantae, so there'll be things that are inter-disciplinary in nature. Some times it'll ask biology, a while asking ecology, and a few times it's going to ask geography also. So we've to be very clear what we do and focussing on only one topic won't suffice. Also, this is often one of the best concerns of our times so current updates and developments are again vital. we've to abreast of what's happening within the world, what went on in the last 20 years, and what future course of action is going to be.
Areas to be Focussed
If we move further or discuss it, we'd like to require a syllabus because of the benchmark. In the syllabus, it's clearly mentioned (1) Environmental Ecology (2) Bio-diversity and (3) global climate change, but the scope of those topics are literally very vast and once we mention vast, actually what all topics are going to be there:
Ecology: It basically means the conceptual a part of the ecology and there are definition based questions also. Its something which is split into two parts, first there are concept-based questions so how we practically see this thing within the world and second is the defining aspect. So we've to be very comfortable with both aspects.
Environmental Issues: it's associated with anthropogenic factors that are operational and there has been a lot of debate and discussion about global climate change, weather, etc.
Bio-diversity: All those anthropogenic changes basically cause disruption and biodiversity, like a revolution, and that we always feel that revolution is extremely good but it's done what it's reduced the biodiversity a part of our food (crops), etc.
Conservational Aspects: for instance, many damages have been caused by various anthropogenic factors to the environment, climate, agriculture, soils entire system. So how and what we will do to conserve this stuff and once we mention conservational aspects we not only consider flora we also consider fauna. So animal conservation or the plant conservation or the ecosystem conservation and each quite conservation activities will inherit picture.
Pollution and its impact: We face pollution on many levels, for instance, pollution which is clear, soil pollution, river or pollution. So, what all kinds of pollution its impact and what's happening within the current scenario.
Climate Change: there's tons of responsibility on the developing and developed nations that the way to reverse the process of global climate change, reduce the emission of gases, etc.
and last but not least is that the Bio-sphere and Biome.
