Greener & Cooler Cities Mission

Objective: A Garden on Every Rooftop

To increase climate and environmental resilience of Chennai city through multi-faceted green rooftops that cool the city, reduce energy load, increase rain water recharge and provide access to fresh, healthy & nutritious food for citizens.

Motives

  • Most rooftops in the city are barren. Planting rooftop gardens and increasing green cover in the city has been proven to mitigate the Urban Heat Island effect, reducing urban temperatures and safeguarding citizens from deadly heat.

  • Greener rooftops can increase the city’s resilience and adaptability to extreme weather events like heavy rain, droughts and pandemics by providing a constant supply of fresh, organic food.

  • Greener rooftops can also significantly lower energy bills and cooling load, contributing to economic and energy savings.

  • Planted rooftops also help detain and retain rain water, reducing the burden on storm water ways and improving ground water recharge.

This Mission is inspired by AARFRC’s Extreme Heat Resilience Alliance

AARFRC_logoThe Extreme Heat Resilience Alliance is a working coalition of NGOs and private-sector organizations (e.g., finance, insurance, humanitarian assistance, scientific research and infrastructure-focused groups), and city governments, that are committed to reducing extreme urban heat risk.

Members of the Alliance will work to combat the effects of extreme heat by participating in one or more of the following activities jointly undertaken by the coalition:

  • Educating decisionmakers about the risks and impacts of extreme heat;
  • Developing policy and governance approaches to create the enabling conditions for heat
    risk reduction interventions;
  • Providing better access to capital for long-term interventions and access to extreme
    heat risk transfer products to build financial resilience to heat;
  • Implementing on-the-ground extreme heat reduction measures.

The Extreme Heat Resilience Alliance recognizes the urgent need to protect people and communities from exposure to, and impacts of, extreme heat, given the substantial and increasing risks of this ‘silent killer.’

FAQs

We encourage you to read our page Benefits of Urban Farms & Gardens to better understand the many reasons why you should consider setting up your own rooftop / ground level vegetable garden.

It is best to check if your building has a structural stability certificate, which is mandatory for any construction, or get a structural engineer to determine strength and load bearing capacity. Many terrace garden setup specialists can assist you with this and will perform a site inspection for you.

The Urban Thottam website is designed to support beginner gardeners in setting up and caring for their gardens. The website contains sections such as the Benefits of Urban Gardening, A Knowledge Base that includes basic guides on various topics, a Crop Calendar and Crop Encylopedia, FAQ section and more. All of these resources make taking up the challenge of starting your own garden easy. Further, there are many inspirational stories of Thottakara Champions and other urban gardening related news that can inspire your neighbours. In the Get Involved section of this website we include many fun ideas that citizens from across the city have contributed that address the issue of how to get more people interested in joining this movement. Really the best thing you can do is become a Champion yourself, and invite neighbours and friends to come and visit your own green patch to see, first hand, how wonderful it is to have one!
