While Roof & Land Greening offers multiple benefits, Planet Symphony for Environment was perhaps the first to demonstrate a clear link between this and the potential to attract rain, particularly in drier regions, by collating studies from multiple regions.

While expensive Roof-scaping options are available, they require a larger investment and ongoing maintenance, which would be accessible to only a portion 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 taller than the surrounding greenery and use excessive heat-absorbing, heat-radiating, and rain-repellent 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.
Please consult local experts on plants most suited to your region.
Likewise, experts can help one with greening solutions for roofs that are too sloped or weak to support heavy potted plants or greenery.
Ideally, also unpave over-concertized areas on the ground to increase percolation and vegetatio.
