India Leading International Solar Alliance (ISA)

Mini-hydel Plants

Use In Mountainous Regions With Streams

Use Energy To Move Small Turbines

Generate Electricity Locally

Environment-friendly

Do Not Change Land Use Pattern

Meet Local Demands

Avoid Large Scale Transmission Towers And Cables

Avoid Transmission Loss

Traditional Knowledge And Practices

Indian People Close To Their Environment Traditionally

Component Of Environment, Not Controller

Environment Friendly Practices

Drifting Away From Traditional Systems

Large Scale Damage To Environment And Rural Heritage

Time To Go Back

Healthcare Example (Medicinal Plants)

Traditional Systems Ignored By Western System

Traditional Healthcare Systems In Great Demand Again

Cosmetic Products Herbal In Composition

Environment Friendly And Relatively Free From Side Effects

Biocomposting

Quest To Increase Agricultural Production

Neglected Use Of Compost, Switched To Chemical Fertilisers
