There's a patch of forest in the middle of Chennai — roughly the size of a cricket pitch — that was planted using the Miyawaki method just six years ago. The saplings, no taller than my knee when planted, are now fifteen-foot trees. The canopy is dense enough to create genuine shade. Birds that hadn't been seen in that neighbourhood for years are nesting there. The air temperature within the patch is measurably cooler than the surrounding concrete.
The Miyawaki method — developed by Japanese botanist Akira Miyawaki — creates dense native forests on extremely small plots of land. Trees are planted at 3-5 per square meter (roughly ten times denser than conventional plantations), using only species native to the region. The density creates competition for light, forcing the trees to grow faster and taller. A Miyawaki forest can reach canopy closure in 3-5 years, compared to 20-30 years for a conventionally planted forest.
Why Conventional Urban Planting Fails
Most urban tree-planting initiatives plant saplings along roads — a single row of identical trees (often non-native species like Gulmohar or Rain Tree) spaced several meters apart. The mortality rate is appalling. Studies in Indian cities suggest that 40-60% of roadside saplings die within the first two years due to inadequate watering, damage from traffic and construction, and cattle browsing.
The surviving trees provide some shade and greenery but limited ecological function. A row of isolated non-native trees doesn't create a habitat. It's decoration — green decoration, which is nice, but it doesn't support the web of insect, bird, and small mammal life that a genuine ecosystem provides.
Miyawaki forests, by contrast, create ecosystems. The dense planting mimics natural forest conditions. Multiple species at multiple heights (canopy layer, understory, shrub layer, ground cover) provide diverse habitats. Native species attract native insects, which attract native birds, which distribute native seeds. Within a few years, you have a functioning ecosystem, not a plantation.
The Indian Practitioners
Afforestt (founded by Shubhendu Sharma, a former Toyota engineer) has planted over 140 Miyawaki forests across India. Sharma learned the method directly from Miyawaki and adapted it for Indian conditions and species. Their forests use only native plants identified through ecological surveys of each planting site.
SayTrees in Bangalore has created over 30 urban Miyawaki forests, several in public spaces like road medians and around lakes. Their Jayanagar model — a tiny urban forest surrounded by apartment buildings — demonstrates that meaningful urban forestry is possible on plots as small as 200 square meters.
Green Yatra and Grow-Trees.com work on larger-scale reforestation but have incorporated Miyawaki methods into their urban projects. The approach is gaining institutional support: several Indian municipalities now include Miyawaki forests in their urban development plans.
Results You Can See
The measurable outcomes of urban Miyawaki forests are genuinely impressive:
Temperature reduction: Urban forest patches can be 2-4°C cooler than surrounding paved areas. In Indian summers where urban temperatures regularly exceed 45°C, this cooling effect is significant for nearby residents.
Biodiversity recovery: A Miyawaki forest in Bangalore documented 42 bird species visiting within three years of planting, in an area where pre-planting surveys found fewer than 10 species. The forest became a habitat island, attracting wildlife from larger green spaces through ecological connectivity.
Water management: The dense root system of a Miyawaki forest absorbs and retains rainfall far more effectively than paved surfaces or conventional plantings. A 200-square-meter forest can absorb several thousand liters of rainwater that would otherwise become surface runoff.
Air quality: Trees absorb CO2 and filter particulate matter. Dense plantings absorb proportionally more per square meter than isolated trees because of the higher leaf area index (more total leaf surface per unit of ground area).
How to Start One
If you have access to land — even a small plot in a residential society, a school compound, or a corporate campus — a Miyawaki forest project is more accessible than you might think.
The process: identify native tree species for your region (Afforestt has published species lists for most Indian regions). Prepare the soil with organic amendments (compost, rice husk, manure). Plant densely — 3-5 saplings per square meter, mixing species and heights. Maintain through regular watering and weeding for the first two years. After that, the forest is self-sustaining.
Cost: roughly ₹500-1,500 per square meter depending on soil preparation needs and sapling availability. A 200-square-meter forest — enough to create a meaningful microhabitat — costs ₹1-3 lakh. Several organisations offer corporate sponsorship packages that cover the cost in exchange for CSR credits.
The satisfaction is disproportionate to the effort. Watching a patch of bare ground transform into a living forest within a few years — hearing bird calls that weren't there before, seeing butterflies return, feeling the temperature drop as you step under a canopy you planted — is one of the most tangible, visceral environmental actions available to an individual.
