Women and IT in India

Current Indicators

•34% Female Adult literacy

•38% Female secondary school enrolment

•44% Female youth illiteracy

•36% of tertiary students in Natural Sciences are female

•19% female teaching staff at tertiary

•23% India’s Internet users are women

Natural Sciences include fields of computer sciences, Engineering, Math, Architecture, Town planning, Transportation and communication

- UNESCO 1999 Statistical Year book

Village Women use Science and Technology Lab - 2 - Land Concept

Why women?

-Agents of change, they influence decisions at home and at the Panchayat

-Water at home is managed by the women

-Girl child is often pulled out of school to ferry water from distant sources

•An ‘All Girls’ team

•Brainstorming Session

•Identify water related issues

About Bangalore

Location : 12’ 58” N Latitude and 77’ 35” E

Longitude

Altitude : 921 Mts. Above Sea

Population : 6 Million

Rainfall : Avg 970 mm over the last 10 years

The Facts

• Bangalore gets its water from the river Cauvery 95 kms away and 500 meters below the city

• Production cost water is very high at Rs 18 a kilo-liter. Will become Rs 26 a kilo-liter.

• Ceiling on the availability of water-1500 Million Liters per Day - good enough for 7 million people only, i.e., by the year 2011.

• Surface and ground water on the decline.

Why harvest Rainwater ?

• A NATURAL RESOURCE PRESENTLY WASTED

• PREVENTS GROUND WATER DEPLETION

• A GOOD SUPPLEMENT TO PIPED WATER

• POSITIVE COST BENEFIT RATIO

• RELATIVELY POLLUTION FREE

• WATER CONSERVATION & SELF-DEPENDANCE

• REDUCES “ECOLOGICAL FOOTPRINT”

What is Rainwater Harvesting?

• Collection

• Filtration

• Storage

• Future Usage

• Recharge

Do’s & Dont’s

Clean-roofs and terraces

Provide adequate storage systems

Pollution free storage systems

X Store—insecticides, rusting iron, manure, detergents

X Use Pets on terrace

X Use chemically polluted water to charge ground water

USEFUL tip : Guppy fish for mosquito control

Scaling the Project

• 2002: Made the school ‘Water Literate’

• 2003: – Installed prototype

– Designed promotional literature

• 2004:– Establish the ‘ Rainwater Resource Center’

– Plan to set up 100 units in 10 villages

• 2005:– Scaling it to 10,000 Households

– Creating global awareness on management of natural resources
