About these Class Notes

Drishti IAS Bhugol, Paryavaran-Parishthitiki tatha Aapda Prabandhan Class Notes are Hindi-medium study notes designed for aspirants preparing for IAS, PCS and other Civil Services examinations.

The content is divided into three major sections — Geography, Environment-Ecology and Disaster Management — allowing students to prepare interconnected topics in a systematic manner. The Geography section begins with the origin and development of Geography and progresses through physical, climatic, oceanographic, regional and Indian Geography.

The Indian Geography portion covers India’s geological structure, physiographic regions and drainage systems, climate, soils and natural vegetation, agriculture, water, irrigation, animal husbandry, natural resources, industries, transport, population and urbanisation.

The Environment-Ecology section covers environment, biosphere and biomes, ecology and ecosystems, environmental adaptation, biodiversity, wildlife, environmental degradation, pollution, Environmental Impact Assessment, soil, climate change, renewable energy, sustainable development and international environmental organisations and conferences.
