Common Issues faced by Aspirants while Preparing Environment and Ecology for UPSC

Here are some common problems the candidates face while preparing Environment & Ecology for UPSC Prelims

Devoting less time

Usually, students devote a lot of time to subjects like polity, geography, and history but not enough to the environment and ecology portion. Since questions from the core subjects like geography, Polity and history are asked in a similar quantity as that of Environment so it is required that equal attention is given to the dynamic subjects like Environment and Ecology. 

What to Read

One major problem with this subject is that there is doubt in the mind of aspirants about sources from which to read. They either do not know which Environment book for UPSC to read or they read too many books and online articles to get a feeling that they have covered the topic in totality.

In a subject like Environment and Ecology, one cannot read each and every topic because the content is very wide as well as there is no rigid boundary line between the content, and the subject is dynamic so one has to limit the content they are reading in order to utilize them qualitatively. Choosing the right UPSC Books for this section is a challenge.

Difficulty in Understanding

One major problem with these subjects is the difficulty in understanding the concept in the first reading. So the aspirants get bored and disinterested while reading these subjects. So the basic thing required while preparing this subject is patience. If a student reads the same material 2-3 times, they will find it interesting and easy. But one should revise them at least 5 times, so as to recall the studied content in the exam. 

Covering Current Affairs

The environment is a very dynamic subject and so requires an equally dynamic approach. Questions are asked about the happenings related to Environment, Ecology, and Biodiversity in the past year or so. Aspirants need to be aware of those happenings in complete detail. Questions on International Organisation, Conventions, etc are more common in UPSC Prelims Paper and these are asked from Current affairs itself so Reading and revising it is very necessary.

Environment & Ecology Books for UPSC and Additional Study Materials 

For Environment and Ecology UPSC, students should select one book which covers all the core concepts and basic information in detail, and apart from this, all other dynamic portion needs to be covered from Newspaper, etc.
