Soil Degradation — Prelims Strategy
Prelims Strategy
For Prelims, a strong foundation in the classification of soil degradation is essential. Memorize the distinct characteristics of physical (erosion, compaction, waterlogging), chemical (salinization, acidification, nutrient depletion, contamination), and biological (loss of organic matter, biodiversity decline) forms.
Focus on specific examples and their primary causes. Pay close attention to government schemes like the Soil Health Card Scheme, National Action Programme to Combat Desertification, and their key provisions and targets.
Understand international agreements such as the UNCCD and the concept of Land Degradation Neutrality. Factual details, such as the number of parameters in the Soil Health Card, are frequently tested. Practice identifying the correct category for various degradation processes.
Create flashcards for key terms like 'sheet erosion', 'gully erosion', 'salinization', 'alkalization', 'soil organic carbon', 'cation exchange capacity', and 'micronutrient deficiencies'. Link current affairs developments (e.
g., budget allocations, new initiatives) to static concepts. For strategic exam preparation, focus on the 'what, where, and how' of degradation and conservation efforts.
