ENVIRONMENTAL SCIENCE AND ENGINEERING L T P C
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 nongovernment
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 © 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.
UNIT II ENVIRONMENTAL POLLUTION
Definition – causes, effects and control measures of: (a) Air pollution (b) Water pollution
© 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 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.
