Desertification — Prelims Strategy

Prelims Strategy

To effectively tackle NEET questions on desertification, aspirants should adopt a multi-pronged strategy. Firstly, master the precise definition: understand that it's land degradation in drylands, distinct from natural desert expansion.

Focus on the 'why' and 'what' – the causes and consequences. Create a mental map linking human activities (overgrazing, deforestation, over-cultivation, improper irrigation leading to salinization) to their specific degradative effects (soil erosion, nutrient depletion, water scarcity).

For numerical problems (though rare in this specific topic), ensure units are consistent. For conceptual questions, pay close attention to keywords like 'primary cause,' 'consequence,' or 'mitigation strategy.

' Be wary of trap options that describe natural processes or beneficial practices as causes. Practice identifying the most effective solutions, such as afforestation, contour farming, and rotational grazing.

Memorize the name and purpose of key international conventions like the UNCCD. A strong understanding of the cause-effect relationships and the distinction between desertification and related environmental issues will be key to scoring well.
