Ōtautahi – 50 million hectares of new forests will be needed to help arrest climate change, according to IPCC data.
Human-induced climate change is causing dangerous and widespread disruption in nature and affecting the lives of billions of people around the world, despite efforts to reduce the risks. Countries can invest and plant in trees, produce pop-up urban forests and map them all by satellite.
It’s important to remember that nature is not only the victim of rising temperatures, but it also has a critical role to play in tackling climate change. Trees provide a vital carbon sink, reducing the rate at which CO2 accumulates in the atmosphere.
Scientists at the Massachusetts Institute of Technology say that in every year since 2000, the world’s forests have absorbed an average of two billion tonnes of carbon dioxide annually.
So how many more trees would we need to plant to limit the rise in global temperatures to 1.5C, the level beyond which the IPCC says some of the harmful effects of climate change will become irreversible?
Based on the UN’s intergovernmental panel on climate change (IPCC) data, NASA says that 950 million hectares of new forests will be needed to help arrest climate change. The World Economic Forum has launched 1t.org with the aim of planting a trillion new trees.
Aotearoa has to plant one billion trees by 2028 to meet its climate change goals. The overall objective, apart from more trees, is to deliver improved social, environmental, and economic outcomes for the country, in addition to driving a low emissions economy.
There are many projects but here are three that are helping the planet:
When the tree is no longer able to capture carbon, it is felled and the timber sold. All the profits go to the investor and three new trees are planted for every one that is cut down.
So far 50,000 people have bought a tree through EcoTree, some as gifts for others. The project’s website features trees in Denmark and France.
Cities are broadly defined as the absence of nature, as places with only hardscapes and humans. This false dichotomy does a disservice to urban centres.
Launched on Kickstarter, the project which aims to create temporary and immersive natural area experiences in un-natural places has already created a pop-up forest in New York’s Times Square. Now it plans to go global with projects planned in cities in Colombia, Indonesia, Kenya, South Africa and the UK.
As well as greening city centres, PopUp Forest aims to mobilize civic support for the creation of urban wild spaces through education and community engagement. For instance, they are urging people to spend at least 40 minutes a week in nature to see their city in a different way.
Using satellite remote sensing and machine learning, Chloris Geospatial says it is measuring the world’s natural capital. By using the language of financial markets, the project says it can convey the positive impact businesses could have on nature.
The data it provides allows organisations to invest with confidence in nature-based solutions by demonstrating their effectiveness in reducing carbon emissions and supporting business’s sustainability goals.
It works by measuring changes in the world’s plant and tree cover, detecting deforestation and measuring the effectiveness of new forest planting. It’s time to put nature on the balance sheet.
