C. Soil and Land Resources

Healthy soil is essential for agriculture and ecosystem health. This section covers soil formation, degradation, and sustainable management practices.

• Soil formation and composition: Factors affecting soil formation, soil horizons, soil properties, and soil classification.
• Soil degradation: Erosion, desertification, salinization, and the impacts of intensive agriculture.
• Sustainable agriculture: Organic farming, integrated pest management (IPM), crop rotation, and conservation tillage practices.
• Land use and land cover change: Deforestation, urbanization, and their environmental consequences.

D. Biodiversity and Conservation

Biodiversity underpins ecosystem stability and provides crucial ecosystem services.

• Biodiversity: Genetic diversity, species diversity, ecosystem diversity, and the importance of biodiversity for ecosystem function.
• Threats to biodiversity: Habitat loss, invasive species, pollution, climate change, and overexploitation.
• Conservation biology: Strategies for protecting biodiversity, including habitat preservation, wildlife management, and species recovery programs.
• Endangered species: Causes of endangerment, conservation efforts, and the role of international agreements.

E. Pollution

Various types of pollution pose significant threats to human health and the environment.

• Air pollution: Sources (mobile and stationary), pollutants (particulate matter, ozone, sulfur dioxide, nitrogen oxides), health effects, and air quality regulations.
• Water pollution (see Water Resources): Reiterated for comprehensive understanding.
• Soil pollution: Sources, types of contaminants, effects on soil health, and remediation strategies.
