Environment and Ecology form a massive chunk of UPSC Prelims (15-20 questions annually). Let’s do an in-depth analysis of some repeated themes.
Q1. Consider the following statements regarding ‘Earth Hour’: (UPSC 2014)
- 1. It is an initiative of UNEP and UNESCO.
- 2. It is a movement in which the participants switch off the lights for one hour on a certain day every year.
- 3. It is a movement to raise the awareness about the climate change and the need to save the planet.
Analysis & Answer: Statements 2 and 3 are correct. Statement 1 is incorrect because Earth Hour is an initiative of the World Wide Fund for Nature (WWF), not UNEP/UNESCO. This highlights a classic UPSC trap: always verify the organizing body of global initiatives.
Q2. What is/are the importance(s) of the ‘United Nations Convention to Combat Desertification’ (UNCCD)? (UPSC 2016)
Analysis & Answer: UNCCD is the sole legally binding international agreement linking environment and development to sustainable land management. UPSC frequently tests the “legally binding” status of environmental treaties.
Why is PYQ Analysis Crucial?
Analyzing Previous Year Questions (PYQs) is the master key to cracking competitive exams like UPSC and MPSC. It provides profound insights into the examiner’s mindset, the weightage of various topics, and the changing trends of the question paper over the years.
By thoroughly studying these questions, aspirants can identify the core areas of the syllabus that yield the maximum marks. It helps in avoiding the pitfall of reading cover-to-cover and instead encourages smart study. We strongly advise students to solve at least the last 10 years of question papers in a simulated exam environment.
Remember, the goal is not just to know the correct answer, but to understand why the other three options are incorrect. This reverse-engineering technique builds a strong foundation for eliminating tricky options in the actual examination hall.
