Japanese microforests invented in the 1970s are transforming cities around the world

A microforest can achieve 100 years worth of growth within a single decade.

City life has its benefits, but usually at the expense of the environment. However, a trend in urban planning has been growing like weeds throughout various metropolitan areas. They’re called “microforests” and they’re bringing nature back to our streets.

The concept of microforests (also known as “tiny forests” or “Miyawaki forests”) was inspired by the work of Japanese botanist and plant ecologist Akira Miyawaki back in the 1970s. Using what is known as the “Miyawaki Method,” people would plant a diverse set of native plants and trees within a dense pace, usually in plots of land less than 100 square feet in size. If properly cared for, these trees and plants grow rapidly. In some cases, according to Euro News, a microforest can achieve 100 years worth of growth within a single decade when compared to the growth rates of regular forests. Which is good since monoforests are subjected to massive deforestation.

While there have been agreements and efforts to combat deforestation, a study from the World Resources Institute showed that 3.7 million hectares of tropical forest land was lost in 2023 alone. That’s ten soccer fields’ worth of trees lost every minute. With the United Nations projecting that 68% of the human population will live in an urban area by 2050, it’s looking like more and more of our world will be colored with gray concrete instead of lush green. But microforests could offset that.

Over recent years, microforests have become more commonplace throughout the world, in England, Belgium, India, Pakistan, China, Japan, and the United States among other countries. This trend of adopting the Miyawaki Method has been proposed and practiced through all levels, from political action to city planning to just a local citizen getting a petition or permission to grow a microforest. It’s not surprising since microforests are a smaller task and ask compared to other environmental proposals being offered.

Not only that, but microforests are shown to be an effective way to improve the environment of a metropolis. They help cool a city down by reducing carbon emissions and providing additional shade from the tall trees. These healthy forests can also help enrich the local soil and water resources in the city, too. They also double as a local wildlife refuge and living space for animals that have been displaced due to city expansion.

The benefits of microforests aren’t limited to just the environment, and provide more than just an aesthetic contrast to the streets and buildings surrounding citizens. Microforests provide a meeting place for organizations and friends like a public park. The cleaner air doesn’t just combat climate change, but also reduces the amount of pollutants and smog inhaled by city dwellers, per the National Institute of Health.

If this is something that interests you for yourself or your community, you can take action. Depending on where you live and if you own property, you could even grow a microforest in your backyard if you wish. If you live in a city, you know how cramped it can be and how cooperation is necessary when living within a mass of thousands of people. Having something like a microforest to cool everyone down, physically and emotionally, can only benefit everyone.

Put on your active citizen hat because the Department of Housing and Urban Development is seeking public comments on a proposed rule.

First, a little background.

In October 2016, HUD published a final rule, "Equal Access in Accordance with an Individual's Gender Identity in Community Planning and Development Programs."


It ensures people have equal access to HUD programs and shelters funded by HUD's Office of Community Planning and Development (CPD) regardless of their gender identity. It's actually an expansion of a 2012 rule that provided equal access to shelters and programs regardless of sexual orientation.

Sounds good so far, right?

The rule is great but only if people — especially those seeking emergency shelter or resources — know it exists.

As part of the rule, HUD is proposing owners and operators of CPD-funded buildings, housing units, and shelters post this rule in public places in their facilities (like bulletin boards and in the lobby) where people can see it. HUD would provide the content of the notice and the owners would just have to print it out and post it. HUD estimates the task will take six minutes.

Here's where all of us come in. HUD is seeking public comment on four things:

1. Whether the printout is necessary and useful.

2. Whether the six-minute estimate is accurate.

3. How to improve the quality, usefulness, or clarity of the document.

4. How to minimize the burden on people required to print out the document.

If you believe it's a good idea for HUD shelters and housing units to post this information, you can submit your comments electronically or by mail until Feb. 23, 2017.

Think giving feedback on something like this is trivial and unnecessary? Ask the genderqueer teen living on the streets who needs a place to crash and doesn't know if they're welcome at a local emergency shelter. Ask the transgender woman who was worried she'd be denied access to a home-buying program.

It may seem small, but to the individuals and families looking for resources and reassurance, it's significant.

More comments and feedback on the issues and proposed policies let the administration know we are paying attention.

This is only the first week of the new administration, and President Trump and his team have set several potentially devastating plans into motion. There's the unsanctioned gag order at the USDA, the devastating executive action prohibiting U.S. aid groups from funding NGOs that advise on or provide abortions, revival of the Keystone XL and Dakota Access oil pipelines, not the mention the promise to begin moving on his border wall.

You may not have the time or emotional energy to respond to every issue or proposal and that's OK.

With so much going on, it's easy to get discouraged and zone out. We have to persist. When we stop speaking up, reading, or getting involved, the administration's decisions go ignored and unchecked. There's just too much at stake to risk that.

Pick your issue: write a comment, make a call, attend a town hall, send a letter. Let Congress and Trump know you won't be silenced, bullied, or ignored. They work for us, and it's time they get a reminder.

Get ready. Your active citizen hat is going to be on for a while.
