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
•Joins hands with
The Rainwater Club

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
