Navi-Mumbai: A city of…

Growth…

Transformations

..

A City ..

In Harmony with Nature

A City…

Rich in Biodiversity

A City…

Managing its Resources…

And now transforming the

Planned City of Navi Mumbai

into an Eco-City.

Why we need an Eco City?

India’s urban population is expected to increase by 10% (over 12 crore) in 2030

Impose a stress on natural resources like land, water & energy

Cities responsible for majority of GHG emissions:

Residential buildings: 30-40%1

Transport sector: 30%2

Important to address problems of pollution and resource crunch

Expected transition

Objectives

To devise an innovative program and study based approach

To estimate the carbon emission of the city before and after implementation of the project/programs.

To identify and focus on critical issues pertaining to three major sectors - Residential, Industrial and Government.

To establish a strong network of government agencies, residents, industrialists, builders and other stakeholders for maximizing the impact of the project activity.

Significant rise of 31% in the number of properties is observed since 2007-08.

Built environment in Navi Mumbai city

Minimal impact on the site and

surroundings

Improve the micro-climate through

better tree cover, cooler ambienttemperatures, shading, etc.

Energy efficient (minimize electricityand fuel consumption) and maximizeuse of renewable sources of energy(solar, wind, etc.)

Energy saving potential up to 30-50%

Water saving potential up to 40-70%and promote maximum recycling and reuse of waste

Promoting Green Buildings and amending the Bye laws

Urban Farming

As a part of smart eco-friendly resilient cities

Do we know where our food comes from?

Why Urban Farming?

Food and nutrition security

Reducing Carbon footprint

Allied biodiversity of a niche

Growing local for better availability

To reduce Urban Heat Island effect

Reduce, Reuse, Recycle

Social awareness among people of all ages

Reaping joy from a simple activity

Eco City Forum

forum of like-minded people from industries , residential areas and commercial sector

Appointing volunteers to act as trainers

Training the trainers

Simple flashcard based presentations

Measure impact

Benefits

Awareness towards treating resources as valuable commodities

Conservation of water and energy

Increased outreach towards sustainability

Summary Development of a low carbon city

Technology demonstrations

Emphasis on Industries, Residential Sector and New Infrastructure.

Sensitization and active involvement of youth, networks, residents and

professionals

Food security

Biodiversity conservation
