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 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.
UNIT III

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 over-utilization
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.
