Click here to download the syllabus of Ability Enhancement Course (AEC - I & II) - Environmental Science: Theory into Practice (under UGCF 2022, with effect from Academic Session 2022-23)

The University of Delhi's Environment Studies (EVS) course, part of the National Education Policy (NEP) framework, covers topics like ecosystems, natural resources, biodiversity, pollution, and global environmental issues, and incorporates practical field work and data analysis to promote understanding of sustainability and environmental conservation. The course structure includes units on the multidisciplinary nature of environmental studies, ecosystem functions, the importance and threats of various ecosystems, and the role of human communities in environmental challenges. 

Course Structure & Content

The EVS course is structured into units, often including:

• Introduction to Environmental Studies: Explores the multidisciplinary nature of the field, the components of the environment (atmosphere, hydrosphere, lithosphere, biosphere), and the concepts of sustainability and sustainable development. 

• Ecosystems: Focuses on the structure, functions (energy flow, nutrient cycling, food webs), and types of ecosystems (forests, grasslands, deserts, aquatic), along with their importance and threats. 

• Natural Resources: Details land resources, minerals, soil, and forests, discussing land use change and the overexploitation of resources like water and energy. 

• Biodiversity and Conservation: Covers the importance of biodiversity, threats to it, and conservation strategies. 

• Environmental Pollution: Examines causes and effects of air, water, and solid waste pollution, as well as nuclear hazards. 

• Global Environmental Issues and Policies: Addresses climate change, global environmental policies, and relevant environmental laws and acts. 

• Human Communities and the Environment: Explores population growth and environmental degradation, natural disasters, environmental ethics, and the relationship between Indian culture and environmental practices. 

Learning Methods & Practical Work

The course employs a range of teaching methods to facilitate learning:

Formal lectures 

Interactive sessions: with visual aids 

Case studies: and hypothetical scenarios 

Fieldwork and practical exercises, such as: 

• Data collection for ecological pyramids 

• Field visits to various terrestrial and aquatic ecosystems 

• Developing working models of ecosystems 

• Documenting environmental assets and polluted sites 

• Study of local ecosystems like forests, wetlands, or ponds
