Prelims 2026 · Environment · Question 23
Which of the following best explain(s) the rationale for protecting mangrove ecosystems in the context of climate resilience?<br/><br/>1. Mangroves reduce tidal energy and store freshwater, making them ideal sites for paddy cultivation in saline estuarine belts.<br/>2. Their salt-sensitive roots filter seawater, making mangroves key to converting coastal land into freshwater aquaculture zones.<br/>3. By withstanding tidal surges and offering biomass resources, mangroves function both as natural bio-shields and livelihood bases for rural communities.<br/><br/>Select the answer using the code given below:<br/>
Answer
3 only
Only statement 3 best explains the climate-resilience rationale. Mangroves act as natural bio-shields against tidal surges and also support livelihoods and biomass-based local use. Statements 1 and 2 add incorrect claims about freshwater storage/filtering and conversion of saline coasts into freshwater cultivation or aquaculture zones.
