AIM
To create awareness in every engineering graduate about the importance of environment, the
effect of technology on the environment and ecological balance and make them sensitive to
the environment problems in every professional endeavour that they participates
OBJECTIVE:
At the end of this course the student is expected to understand what constitutes the
environment, what are precious resources in the environment, how to conserve these
resources, what is the role of a human being in maintaining a clean environment and useful
environment for the future generations and how to maintain ecological balance and preserve
bio-diversity. The role of government and non-government organization in environment
managements.
UNIT I ENVIRONMENT, ECOSYSTEMS AND BIODIVERSITY 14
Definition, scope and importance of environment – need for public awareness - concept of an
ecosystem – structure and function of an ecosystem – producers, consumers and
decomposers – energy flow in the ecosystem – ecological succession – food chains, food
webs and ecological pyramids – Introduction, types, characteristic features, structure and
function of the (a) forest ecosystem (b) grassland ecosystem (c) desert ecosystem (d) aquatic
ecosystems (ponds, streams, lakes, rivers, oceans, estuaries) – Introduction to biodiversity
definition: genetic, species and ecosystem diversity – biogeographical classification of India –
value of biodiversity: consumptive use, productive use, social, ethical, aesthetic and option
values – Biodiversity at global, national and local levels – 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 conservation of biodiversity.
Field study of common plants, insects, birds
Field study of simple ecosystems – pond, river, hill slopes, etc.
UNIT II ENVIRONMENTAL POLLUTION 8
Definition – causes, effects and control measures of: (a) Air pollution (b) Water pollution (c)
Soil pollution (d) Marine pollution (e) Noise pollution (f) Thermal pollution (g) Nuclear hazards
– soil waste management: causes, effects and control measures of municipal solid wastes –
role of an individual in prevention of pollution – pollution case studies – disaster management:
floods, earthquake, cyclone and landslides.
Field study of local polluted site – Urban / Rural / Industrial / Agricultural. 19
UNIT III NATURAL RESOURCES 10
Forest resources: Use and over-exploitation, deforestation, case studies- timber extraction,
mining, dams and their effects on forests and tribal people – Water resources: Use and overutilization of surface and ground water, floods, drought, conflicts over water, dams-benefits
and problems – Mineral resources: Use and exploitation, environmental effects of extracting
and using mineral resources, case studies – Food resources: World food problems, changes
caused by agriculture and overgrazing, effects of modern agriculture, fertilizer-pesticide
problems, water logging, salinity, case studies – Energy resources: Growing energy needs,
renewable and non renewable energy sources, use of alternate energy sources. case studies
– Land resources: Land as a resource, land degradation, man induced landslides, soil erosion
and desertification – role of an individual in conservation of natural resources – Equitable use
of resources for sustainable lifestyles.
Field study of local area to document environmental assets – river / forest / grassland / hill /
mountain.
UNIT IV SOCIAL ISSUES AND THE ENVIRONMENT 7
From unsustainable to sustainable development – urban problems related to energy – water
conservation, rain water harvesting, watershed management – resettlement and rehabilitation
of people; its problems and concerns, case studies – role of non-governmental organizationenvironmental ethics: Issues and possible solutions – climate change, global warming, acid
rain, ozone layer depletion, nuclear accidents and holocaust, case studies. – wasteland
reclamation – consumerism and waste products – environment production act – Air
(Prevention and Control of Pollution) act – Water (Prevention and control of Pollution) act –
Wildlife protection act – Forest conservation act – enforcement machinery involved in
environmental legislation- central and state pollution control boards- Public awareness.
UNIT V HUMAN POPULATION AND THE ENVIRONMENT 6
Population growth, variation among nations – population explosion – family welfare
programme – environment and human health – human rights – value education – HIV / AIDS
– women and child welfare – role of information technology in environment and human health
– Case studies.
