GE3451 Environmental Sciences and Sustainability Important questions

COURSE OBJECTIVES:
 To introduce the basic concepts of environment, ecosystems and biodiversity and
emphasize on the biodiversity of India and its conservation.
 To impart knowledge on the causes, effects and control or prevention measures of
environmental pollution and natural disasters.
 To facilitate the understanding of global and Indian scenario of renewable and
nonrenewable resources, causes of their degradation and measures to preserve them.
 To familiarize the concept of sustainable development goals and appreciate the
interdependence of economic and social aspects of sustainability, recognize and analyze
climate changes, concept of carbon credit and the challenges of environmental
management.
 To inculcate and embrace sustainability practices and develop a broader understanding on
green materials, energy cycles and analyze the role of sustainable urbanization.

UNIT I ENVIRONMENT AND BIODIVERSITY
Definition, scope and importance of environment – need for public awareness. Eco-system and
Energy flow– ecological succession. Types of biodiversity: genetic, species and ecosystem
diversity– values of biodiversity, India as a mega-diversity nation – hot-spots of biodiversity –
threats to biodiversity: habitat loss, poaching of wildlife, man-wildlife conflicts – endangered and
endemic species of India – conservation of biodiversity: In-situ and ex-situ.

UNIT II ENVIRONMENTAL POLLUTION
Causes, Effects and Preventive measures of Water, Soil, Air and Noise Pollutions.
Solid, Hazardous and E-Waste management. Case studies on Occupational Health and Safety
Management system (OHASMS). Environmental protection, Environmental protection acts .

UNIT III RENEWABLE SOURCES OF ENERGY
Energy management and conservation, New Energy Sources: Need of new sources. Different
types new energy sources. Applications of- Hydrogen energy, Ocean energy resources, Tidal
energy conversion. Concept, origin and power plants of geothermal energy.

UNIT IV SUSTAINABILITY AND MANAGEMENT
Development , GDP ,Sustainability- concept, needs and challenges-economic, social and aspects
of sustainability-from unsustainability to sustainability-millennium development goals, and
protocols-Sustainable Development Goals-targets, indicators and intervention areas Climate
change- Global, Regional and local environmental issues and possible solutions-case studies.
Concept of Carbon Credit, Carbon Footprint. Environmental management in industry-A case study.

UNIT V SUSTAINABILITY PRACTICES
Zero waste and R concept, Circular economy, ISO 14000 Series, Material Life cycle assessment,
Environmental Impact Assessment. Sustainable habitat: Green buildings, Green materials, Energy
efficiency, Sustainable transports. Sustainable energy: Non-conventional Sources, Energy Cyclescarbon cycle, emission and sequestration, Green Engineering: Sustainable urbanization- Socioeconomical and technological change
