GE2021 ENVIRONMENTAL SCIENCE AND ENGINEERING
(Common to Civil,
CSE, IT & Biomedical Degree Programmes)
AIM
The aim of this course is 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
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 – biogeographically
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
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.
UNIT III NATURAL RESOURCES
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
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 organization environmental 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 protection
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
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.
