ISSUES: According to a majority of experts, yesterday’s Climate Crisis is today’s Climate Catastrophe and tomorrow’s Climate Chaos (by 2030 when global average temperatures go up by over 2°C compared to pre-industrial era. At this time, it is expected to impact every home (like Covid did) and our responses will not be sufficient to arrest a full-fledged Environmental Meltdown, unless billions of citizens chip in now.
Planet Symphony’s 3R Formula of Roof & Land Greening, Rainwater Management and Renewable Energy is the most scientific, realistic and organic solution for High & Mid Income Group Citizens and Businesses to implement in their own premises or areas of their choice. If done with massive community participation, this can reverse Global Warming and cool down the planet at least partially within the next 1-3 years. Planet Symphony also recommends other Lifestyle changes for the Environment including Sustainable Food Choices.
While Roof & Land Greening offers multiple benefits, PSE was perhaps the first to show a clear connection between this and the potential to attract rain, especially in drier regions, collating multiple studies from different regions. While expensive Roof-scaping options are available, they need a larger investment and maintenance, which would be accessible to only a section of the population. PSE recommends economical, functional Roof Greening: 3-5 feet tall plants in light-weight pots or grow bags covering 50-70% of the roof and 10-15 trees per 2400 Sq feet (1 ground) on land. The primary goal is to create shade and reduce temperatures.
NECESSITY: Roofs Greening is an urgent Climate Imperative today as most buildings are much taller than the greenery and also use a surfeit of heat absorbing, heat radiating and rain-repellant materials. This makes all discourse on Rainwater Harvesting lead to a fundamental question: What can one harvest if there is no rain? In other words, Step 1 is to convert Rain-Repellent Cities into rain friendly ones by greening every possible area including roofs and walls of buildings.
SCIENTIFIC BASIS: It is known that Trees create rain. They also help draw the rainwater into rivers, lakes and underground water table. The 5.5 million sq km Amazon Forests make more rain when there is more greening of fresh leaves. Can micro systems replicate this? They can, as this video from USA and this one from Ecuador show. Greenery also draws moisture from water bodies to land & non-green areas repel rain as this UK video proves.
ROOF-GREENING LEADERS: Europe initiated Roof Greening in 1970s and USA greened nearly 100 million square feet of green roofs in every possible climate zone from around 2001-2011 and has continued to do lots more. Several cities in USA including Chicago, Washington DC, New York & Houston and countries like Canada, Singapore, Denmark, Switzerland and France have initiated or incentivised Roof Greening with excellent results. These need to be replicated everywhere.
HOW TO GO ABOUT IT: Always choose greenery according to the type of roof and climate you have. Flat roofs are usually fine with even 50-60% of plants at least 3-4 feet in height in pots (or grow bags). These can create shade on your roofs and immediately bring the temperature down. One can find other solutions for sloped roofs or vertical greening on walls. Similarly, there are options of various plants for desert type of climates, for cold weather where the greening itself mitigates the cold, tropical and sub-tropical climates etc. In places with extreme heat, we may need to grow roof plants in shade but the greening will eventually bring down the temperature, though it may be a challenge over the first few years but countries like Dubai are embracing it in a large scale and a few others like Egypt are exploring potential in eventually providing clean food supply. Remember that Roof or Land Greening is not an expense but only an investment.
Rainwater harvesting at a micro-level is a common sense idea which was in vogue for centuries but has thoughtlessly been discarded in many regions in recent times. It is being re-appreciated now that scientific Roof Rain Water Harvesting solutions can exponentially increase water management at the micro as well as macro level.
HOW TO HARVEST RAINWATER: A combination of Recharge Wells, Sumps and where possible, traditional dug wells, can ensure that months of drinking water supply can be harvested within a few hours of good rains and also raise the overall water table. According to Rain Centre, Chennai, 1 inch Rainfall in a 2000 Sq Ft roof can translate to at least 4731 liters of water harvested. It is equally imperative to restore zillions of lost water bodies or create new ponds and lakes wherever possible to restore biodiversity, that is necessary for our species too.
WATER MANAGEMENT LEADERS: Parts of Canada, UK, USA, New Zealand, Uganda, Thailand etc salvage some rainwater, it is imperative even for them to adopt more holistic measures and for other countries to follow suit. A few NGOs in countries like India run inter-village Water Salvaging and Storing competitions, which has led to a huge Climate awareness and action by citizens. Some water bodies are also being restored by committed individuals and NGOs as well as some Governments but replicating their efforts and exponentially scaling up is the need of the hour.
PSE is a “By the people – for the people” initiative. While we request Governments, Charities and Philanthropists to be our Climate Patrons, we also wish to directly engage with the people who can be our Environmental Fund Generators by donating a token $1 or Indian Rs 10 or higher, as a symbol of solidarity with the PSE’s Vision and Activities. The Funds will be carefully deployed by PSE directly and/or allocated to collaborators and other organizations focused on similar initiatives.
Please use Donate Buttons or QR codes to donate in Dollars or Indian Rupees.
