When cities grow fast, it often hurts the environment. Our cities, which used to be full of different plants and animals, are now mostly concrete and roads. The air we breathe gets heavy with bad stuff, and the nice shade of trees becomes something we only remember. This is why urban reforestation – planting trees in cities – is so important. It's a strong way to fight against too much concrete and a hopeful sign for healthier, happier cities.
In the middle of Nepal, in the busy city of Kathmandu, an amazing social group called Lily Leaves Social Enterprises is leading this green change. They aren't just planting trees; they're growing small forests, transforming empty city spaces into lively natural areas, and bringing life back to our communities. Their special work uses a new approach: the Miyawaki method.
Imagine a world where forests grow back not in hundreds of years, but in just a few decades. This was the bold idea of Dr. Akira Miyawaki, a brilliant Japanese plant scientist and nature expert. Born in 1928, Dr. Miyawaki spent his life learning about and fixing natural places. His deep understanding of how powerful local plants can be led him to create the "Miyawaki method," a way of planting that has changed city tree planting all over the world.
Dr. Miyawaki's idea was simple but very effective: plant local trees, plant them close together, and let nature do the rest. He saw that old ways of planting trees often didn't create the rich mix of life and strength that real forests have. Instead, his method focuses on making mini-forests that can take care of themselves, have many different kinds of life, grow up to 10 times faster and are 30 times thicker than normal tree plantings.
The main ideas of the Miyawaki method are very interesting:
· Picking Local Plants: This is the most important part. Only trees and bushes that naturally grow in the area, and are perfect for the local weather and soil, are chosen. This makes sure the forest grows well on its own and helps local animals.
· Preparing the Soil: The soil is made rich with natural materials, making a perfect base for roots to grow quickly.
· Planting Close Together: Many young trees of different local types are planted very close to each other. This makes them compete for sunlight, forcing the trees to grow tall quickly, just like trees in a natural forest.
· Layers of Plants: The planting includes different heights of plants tall trees, shorter trees, bushes, and ground cover making it like the complex structure of a full-grown forest.
· Early Care: For the first few years, the young trees are watered carefully and weeds are removed. But after this first stage, the forest can take care of itself and doesn't need much help from people.
What you get is a thick, lively, and very strong forest that quickly creates its own small climate, supports many different insects and birds, and gives many good things for the environment.
Nepal, with its beautiful Himalayan Mountains, has a strange problem in its cities. Places like Kathmandu Valley, which used to be surrounded by green hills, are now facing serious damage to the environment. The two big problems are air pollution often seen as a thick haze and the sad loss of green spaces. This is affecting people's health and how well they live. The spread of concrete has covered farm lands, riverbanks, and open areas, leading to much less natural space to clean the air and making city areas much hotter.
This is exactly where the Miyawaki method becomes a strong, local solution. Its ability to rapidly create thick, diverse natural areas makes it perfect for dealing with Nepal's city environmental problems:
· Fighting Air Pollution: These small forests act like strong natural air cleaners. The thick leaves catch tiny particles, soak up harmful gases like carbon dioxide, and release oxygen that we need to live. Imagine how much good dozens of these small forests could do all over Kathmandu!
· Making Hot Cities Cooler: Concrete and roads soak up and release heat, making cities much hotter than the countryside around them. The thick tops of a Miyawaki forest provide important shade, and water vapor from the leaves helps cool the air, giving much-needed relief from the burning summer heat.
· Bringing Back Different Kinds of Life: When we lose green spaces, we also lose the complex web of life that depends on them. Miyawaki forests, by focusing on local plants, create vital homes for local birds, insects, and tiny living things, greatly helping biodiversity conservation (keeping many different kinds of life). This brings back a natural balance to city environments.
· Filling Up Underground Water: The dense roots improve how well water can get into the soil, letting rainwater soak into the ground more easily. This helps refill underground water supplies – a very important benefit in a place that is facing more water problems.
· Making People Feel Better: Beyond the tangible environmental benefits, these green havens offer peace and quiet. Studies consistently show that being in nature lowers stress, improves mood, and helps people feel more connected. Imagine a child growing up with a lively forest playground just a few steps from their home.
This is where the story of Lily Leaves truly shines. Understanding how much good the Miyawaki method could do, this forward-thinking social group has fully adopted it to lead efforts to plant trees in cities all over Kathmandu Valley. Lily Leaves began its important environmental work in 2023. They are not just planting trees; they are growing small forests, transforming empty city spaces into lively natural areas, and bringing life back to our communities.
Lily Leaves has smartly focused its efforts on important city routes like the Bagmati and Bishnumati corridors (areas along the rivers). These riverbanks, which used to be natural flood areas, dumping sites since so long and places with many different kinds of life, have suffered greatly from being taken over, trash being dumped, and a general lack of green plants. By using the Miyawaki method in these areas, Lily Leaves is systematically transforming neglected parts into vibrant, self-sustaining forests. Lily Leaves has transformed this site to beautiful mini forest providing habitat to birds, insects, small animals etc.
It's important to remember that since Lily Leaves started its work in 2023, the young trees they've planted are still growing. These reforestation saplings haven't grown into fully mature trees yet, so they are still on their way to providing all the environmental benefits we expect from a full-grown forest. However, the beauty of the Miyawaki method is its speed, and we can already see the promising beginnings of these new green spaces.
One of their most inspiring projects is along the Bishnumati River in the Tankeshori area. Where there was once only bare land and trash, now stands a flourishing young Miyawaki forest, buzzing with life. The transformation is palpable, not just in the greenery but in the faces of the local people.
"Before Lily Leaves came, this area was an ugly sight," shares Kamala Devi, who has lived along the Bishnumati corridor her whole life. "It was dusty in the dry season and muddy when it rained. Now, the air feels cleaner, and we see so many different birds. My grandchildren love to come here and look at the growing trees. It’s like a miracle!"
Another touching example is along the Bishnumati River near Kuleshwor. This once-ignored stretch is now home to a growing Miyawaki forest, providing much-needed shade and a touch of natural beauty to a very crowded area. "We never thought our riverbanks could look like this," says Suresh Tamang, a local shop owner. "The growing trees have made a huge difference. It’s cooler, and there’s a feeling of calm here that was missing before. Lily Leaves has given us a gift."
These stories are not just tales; they are strong proofs of how much good Lily Leaves is doing in the lives of everyday people. They are a testament to the fact that urban reforestation is not merely an environmental endeavor but a social one, directly improving the well-being and pride of communities, even as the young trees continue to mature.
At its heart, the Miyawaki method, used by social groups like Lily Leaves, is a powerful way to help with biodiversity conservation (keeping many different kinds of life). In the rush to build cities, we often forget the complex web of life that exists under our feet and above our heads. Local trees and plants are not just pretty additions; they are the basic parts of local natural systems.
By carefully picking and planting local types of plants from the towering Kapur, Bagam Beli, Tej Patta and Chap trees to the vibrant Lalupatey, Parijat, Neem, Ghanti Phool and various plants used for medicine Lily Leaves is actively restoring the natural balance of Kathmandu's city areas. These local plants are closely connected to the local animals. They provide important food for local birds, insects, and small animals. They offer shelter and places to build nests, letting local animals thrive in an otherwise difficult environment.
Consider the chain reaction: as more native plants flourish, more helpful insects are attracted, leading to healthier plant growth cycles. More insects mean more food for birds, which in turn helps control harmful bugs naturally. It's a beautiful, self-controlling system that cities badly need. Lily Leaves isn't just planting trees; they're re-making the complex web of life, one local young tree at a time. This dedication to biodiversity conservation is what truly makes their approach special, and we are eagerly watching as these young ecosystems develop their full potential.
The successful use of the Miyawaki method by Lily Leaves offers a strong look into what the future of city growth in Nepal could be. It shows that fast city growth doesn't have to mean losing our natural heritage. In fact, it can be a chance to create new things and add green structures right into the core of our cities.
Imagine a Kathmandu where every forgotten patch of land, every bare riverbank, and every unused park turns into a small, thriving forest. The potential is huge. The Miyawaki method, with its proven effectiveness and relatively quick results, can become a main part of planning sustainable cities across Nepal. Even though the saplings are still growing, the promise of these future mini-forests is clear.
For this idea to fully happen, however, it needs efforts from many sides:
· More Social Groups: The success of Lily Leaves can inspire other social groups, community organizations, and non-profits to use similar methods. The more people involved, the faster the green change can spread.
· Public Support: Ongoing public awareness and involvement are very important. When communities understand the big benefits of these green spaces, they become active in protecting and caring for them. Volunteering for planting days, reporting damage, and simply enjoying these spaces responsibly all help them succeed.
· Helpful Rules and Government: Local and national governments have a key role to play. Rules that encourage city greening projects, set aside land for tree planting, and make approval processes easier are essential. Adding Miyawaki forests into city plans, providing money for such projects, and encouraging partnerships between public and private groups can speed up the greening of Nepal's cities. Imagine city governments actively working with groups like Lily Leaves to make their cities greener!
The future of city areas in Nepal can be one where people and nature live together in harmony. The Miyawaki method offers a practical, impactful way towards this greener, healthier, and more diverse future, even as the new forests mature.
To sum up, how important the Miyawaki forest planting method is, especially in the crowded city areas of Kathmandu Valley along the Bagmati and Bishnumati rivers, cannot be overstated. It offers a strong, scientifically proven answer to the urgent environmental problems our cities face.
Lily Leaves, through its strong dedication and smart use of this method, is not just planting trees; it's pushing for urban reforestation (planting trees in cities), supporting biodiversity conservation (keeping many different kinds of life), and ultimately, cultivating a more livable, healthier, and happier urban environment for everyone. Their work is a testament to the fact that even in the most crowded cities, nature can reclaim its rightful place, enriching our lives in countless ways. We are watching these new forests grow with anticipation, knowing that with time, their impact will only deepen and strengthen.
Let's stand together, hand in hand with groups like Lily Leaves, to take care of our city's "lungs," one Miyawaki forest at a time. The future of our cities, and truly our own well-being, depends on it.
