- Drought, forest fires and increasingly frequent storms. Climate change is destroying our forests. All over the world, people are looking for ways to keep them from dying out. Yet nature itself knows best what forests need to thrive.
Reforestation works not only in the countryside, but also in the city. In urban areas, planting trees can help combat climate change, restore ecosystems and keep cities cooler - as forest scientist Stefan Scharfe well knows. He’s already planted 14 ‘tiny forests’ in Germany and Poland. The concept of planting dense, fast-growing woodland in urban wastelands was originally developed by Japanese botanist Akira Miyawaki.
In the shade of a multi-storey car park on the grounds of a hospital in the city of Herford, Scharfe has planted native plants, shrubs and trees close together. "Preparing the soil is key,” he says. "What we do is imitate a forest soil that’s decades old." The mini forest lowers the air and soil temperature in the summer heat and provides shade as well as a habitat for birds and insects.
Miriam Prochnow and Wigold Schaffer have dedicated their entire lives to saving the Atlantic Forest in Brazil. "We are witnessing an unprecedented crisis for humanity and cannot afford not to fight," says Prochnow. In the 1970s, the two started growing tropical trees on their terrace. Today they run a kind of non-profit tree nursery with 25 employees, and grow 200 different, mainly old species. To date, they’ve planted nine million trees, combatting clear-cutting in the Atlantic Forest.
Meanwhile, researchers at the Eberswalde University for Sustainable Development in Germany want to gain a better understanding of the forest ecosystem with the help of Indigenous peoples. They’ve been working with Colombia’s Kogi people, known for their intuitive approach to nature. Their views on drought and pest damage provide inspiration for scientists like Carsten Mann: "For me, the main message of the Kogi is that it will be difficult to work against the laws of nature, and that we need to accept that." The researchers now want to use the knowledge of the Kogi to better protect forests in Germany.

I hate when I see greenery removed from public spaces and replaced with some stupid "art" installation or just concrete slab 🤬🤬
trees are only part of the solution. restoring wetlands and watersheds is another one that I rarely hear these eco-friendly people talk about.
It's also about buffering heat . Put trees around houses so it's not only hot rooftops..... for miles and miles . Trees can be an asset to city's.
Tree is important to human life. No tree no water no life
Trees are our best environmental friends. They store CO2 in the soil and filter air for us. They do more good to us than harm. So, please everyone, plant a tree if you can. Big change starts with a small step. If we all act and work together, we absolutely can avert the catastrophic outcome.
Wish there were projects in central and southern African as well. So many beautiful trees slashed and burned to make way for grazing land. Wish there was a project to educate substance farmers that planting trees especially on the mountains will help store water in the surrounding land, replenish the water table and lesson crop failure.
Something for each of us to think about. Creating a tiny forest can be your legacy that will go on into the future and give meaning to your life, while paying it forward for the earth.
It was a great documentary shared by a respectful ( DW ) documentary channel .thank you for sharing.. reforestation a great work for returning environmental health for fighting climate changes...
They have been affected in different ways even though the bad ones, but restoring the tree is the best strategy for preventing climate change. 🎉🎉
Indeed natural forest was the best climate regulator, air conditioner, air purifier, natural ioniser, water catchment system aka flood regulator, erosion mitigator, and natural shade/ shelter.
After the 10 minute mark, the Kogi come into the documentary and offer us timeless sage wisdom. I'm so glad I saw that whole section.
nature rules everything. nature rules all.
My dad and I planted our first tree this year in Warsaw, Poland. We planted it in a lawn in our neighborhood. There was so little rain that I kept watering it weekly unit beginning of October. I expect I'll have to water it regularly throughout next spring and summer, until it grows bigger and stronger. I'm planning to plant more next year. If all of us plant just one tree and then take care of it for a while until it grows strong roots, we would resolve the issue of deforestation.

Thanks much for the overview of current efforts, DW. Quite heartening. I hope you can delve deeper into the processes that make this successful on your subject matter specific channels.
Great ❤❤❤!. Thanks x
The council seem to be on a rampant crusade to cut down as many trees as they can where I live. Over the last few years some absolutely beautiful Chestnut, Beech, and Cedar trees have been felled along with too many of the old Lime, Yew, and nearly all the Elm. It's of course down to safety, disease, access or some other pressing issue, but old trees like that need to be treated with more respect, IMO...
I THANK you from the bottom of my heart and soul...
Got inspired to plant few trees in my little backyard this fall. Thank you for educating me.
Yes!
