A 2,500 sq. (sq) metres (m), or 0.6-acre, of barren patch in Malad in Mumbai has reworked right into a mini urban forest with seven to 9 ft (ft) timber in lower than 9 months.
Between January and September, the Indian Navy, together with atmosphere group Green Yatra, developed Mumbai’s largest dense plantation so far by utilizing the Miyawaki approach (see field) on a plot in entrance of the primary campus of Indian Navy Station (INS) at Hamla in Marve-Malad.
Forests grown beneath the Miyawaki technique – developed by Japanese botanist and plant ecology skilled Dr. Akira Miyawaki – have improved carbon-dioxide absorption, have lowered noise and mud , and added extra inexperienced floor space, as in comparison with monoculture plantation.
Plants develop 10 occasions quicker and 30 occasions denser than conventional strategies, with any common plantation space supporting 45 saplings throughout 150 sq. ft.
At INS Hamla, 10,500 saplings of 40 completely different native species have been planted in phases between January 18 and February 27.
“The forest is flourishing under our care, and the plants have grown nine-ft tall with almost 100% survival rate. The location of the forest within the boundaries of the base provides protection to the plants, which are expected to become self-sustaining within a year,” mentioned Captain Sridhar Warrier, chief public relations officer (CPRO), Southern Naval Command.
According to Green Yatra, all the plantation course of – previous to January – took 2,400 labour hours and 440 machines, together with excavators and dumpers, and concerned excavating the mattress space for the three-ft-deep plantations.
The course of included laying 200 dumpers price of soil reminiscent of 165 tonnes of black soil and biomass, handbook stone elimination, levelling the land, creating a one-ft-excessive mattress mount, making pathways and channels to produce six litres of water per metre sq., and planting 10,500 saplings in two phases with every not less than two-years-previous.
The plantation technique utilizing this method focuses on density, mentioned Pradeep Tripathi, founder, Green Yatra.
“This is against the average plantation density of three to five plants per sq m depending on the site. Plantations at INS Hamla were four plants per sq m since the site is very close to the coast and there is high wind speed. Also, saplings support each other’s growth and prevent sunlight from reaching the ground halting the growth of unnecessary weeds,” he mentioned.
Fixing assist sticks to every plant, remulching, and sprinkling microbes and boosters for correct plant growth are an integral a part of put up-plantation upkeep.
“Whenever there was any water shortage, the navy supported us with their own resources. We have had an overall survival rate of 98.5%,” mentioned Tripathi.
Native timber included a mixture of deciduous and evergreen fruiting tree species reminiscent of amla, neem, mahua, kokam, mango, silk cotton, banyan, and pleasure of India.
Around 40 species have been divided into 4 layers, together with 18 tree species, 12 sub-timber, 4 cover species, and 6 shrubs as much as three ft in measurement.
Captain Warrier mentioned the same plantation drive – of 15,000 extra saplings by subsequent February — was within the works referred to as the Miyawaki section II, which might be positioned close to the identical web site. “The first phase was funded by DCB Bank. This method of indigenous forest by native trees produces rich, dense and efficient protective forest in 20 to 30 years, while natural succession will need 200 years,” he mentioned.
Experts mentioned such plantations have been welcome for urban environments which can be quick shedding inexperienced cowl however don’t match the advanced forest ecosystem. “These techniques cannot be substituted for natural forest, which represent the non-artificial cycle of carbon, oxygen, minerals and biodiversity, and cannot be replicated by artificial means. For urban spaces, these small green zones may have limited benefits such as reduction of particulate matter, improved oxygen supply, and minimal micro-climatic changes. However, these urban greening concepts cannot be undermined as there is hardly any land available amid the concrete expanse in major cities in the country,” mentioned Dr. Subhash Ashutosh, director-basic (D-G), Forest Survey of India (FSI), Dehradun.
STATUS OF MIYAWAKI PLANTATIONS IN MUMBAI
Praveen Pardeshi, former commissioner of the Brihanmumbai Municipal Corporation (BMC), had final 12 months proposed to plant 377,416 timber beneath the Miyawaki undertaking at a value of Rs 35 crore throughout 100 places unfold over 31 acres in Mumbai. “Our intention was to have half of the recreational areas of every layout should be a Miyawaki forest. Among the 100 locations, plots in Malad, Colaba, Worli and Priyadarshini Park have yielded good results. The idea is to transfer the cost of greening not just to the public exchequer but also the Mumbaikars gaining the most. The security of these plantations is also automatically protected,” mentioned Pardeshi.
Besides BMC’s efforts, 5 main plantations throughout the Mumbai Metropolitan Region (MMR) have been accomplished by Green Yatra. The following are the initiatives:
Central Railside Warehouse Company Ltd, Jogeshwari, space 2,300 sq. m, ,7000 crops, 40 species accomplished in three phases
Bhandup Complex, space: 1,200 sq. m, 3,500 crops with 46 species
State Reserve Police Force Premises in Taloja, Navi Mumbai, space: 700 sq m, 2,000 crops with 40 species
Ambernath, space: 100 sq. m, 320 crops with 40 species
INS Hamla, space: 2,500 sq. m, 10,500 crops in section I with 40 species and one other 15,000 crops proposed in section II in February, 2021.
100 YEAR OLD FORESTS IN 10 YEARS
With over 3,000-odd urban mini-forests created utilizing the Miyawaki plantation approach, which might accommodate 12,000 saplings in a single-acre land, can improve the variety of timber per individual inside Mumbai via native tree plantation inside a quick span of time.
The options of this method embody:
– 10 occasions quicker progress
– 30 occasions denser than conventional plantations
– More biodiverse
– Better noise and mud discount
– 30 occasions higher carbon dioxide absorption
– Native and natural
