Inter Disciplinary Project

IX - X (2017-18)

TOPIC- WATER CONSEWRVATION- TEMPLES OF MODERN INDIA - MULTI PURPOSE RIVER VALLRY

PROJECTS - THEIR ROLE IN WATER MANAGEMENT.

Clean fresh water is essential for healthy life. However , today , nearly one billion people don't

have access to clean water . Water Scarcity is the lack of sufficient available water resources to

meet water needs within a region . It affects every continent. Depleting reservations and failing

groundwater table has led to an acute water shortage in several states of India as well.

Multipurpose river valley projects in India were started with the basic aim of meeting the critical

requirements of irrigation for agriculture , electricity for industries and flood control . The

importance of the dams at that time can be inferred from the fact that dams were regarded as "

The Temples of Modern India" by our first Prime Minister , Pandit Jawahar Lal Nehru . Accordingly,

dam construction was given such a high priority in India's economic plans. Till now "Irrigation and

hydro - power have been the major objectives of the water resources development in India. "

These " Temples of Modern India" or rather Multipurpose Projects ( or River Valley Projects ) have

not only solved much of the water scarcity problem but also boosted the Indian economy.

General Instructions:-

• A single inter - disciplinary project is to be made in one file containing all subjects.

• The first page of the projects should have the following details: o Name of the student o Class and section o Session

• The second page must have the following :

Subject Remarks by Teacher Teacher's Signature

• The projects should be hand written on plan white / coloured A4 size sheets

• All subject specific tasks or homework to be placed in a single file ( spirally bound or otherwise).

• Cover page, table of contents, acknowledgements , bibliography should be included.

• It should be well presented , researched and pictorial .

• Each subject should not exceed 8 sheets .

• The project carries 20 marks for each subject:

• Relevance of the content - 5 marks

• Expression of the ideas - 4 marks.

• Presentation- 4 marks

• Research - 4 marks

• Creativity- 3 marks

TASK 1

1. Imagine you visited one of these Multipurpose River Valley Projects. You did a lot of research on

the project as well. You learnt about its water capacity, height of the dam, uses, name (s) of the

river (s) it is built upon, date of inauguration, their role in water management, etc.

Write a diary entry sharing your views and experiences of your visit. You may also include

information about the multipurpose project. ( 100-120 words)

2. The Tehri dam construction controversy has pitted development against environmental

conservation, modernity against traditional values, and the state against communities. Express

your views on the issue.

3. Read the newspapers everyday. Collect articles related to water conservation. Make a collage

of the same on an A4 size sheet and file it.
