Planting trees can sometimes be a carbon-offset box-ticking exercise, but reforestation is a long-term commitment that supports communities, promotes biodiversity and tackles the climate emergency.
Large-scale tree-planting projects are politically popular and media-friendly, but without effective planning and long-term management, they can do more harm than good.
Even if they can’t save us from climate change, society still depends on forests.
Zero emission? Carbon neutral? Carbon negative? What does it mean to achieve ‘net-zero’ emissions?
Large areas targeted for forest restoration in Africa are covered by savanna and grassland, which provide important ecosystem services that would be lost should they be converted to forests.
It depends on where and how it’s grown, and how it is disposed of or recycled.
Regreening Africa works directly with 500,000 households to restore one million hectares of agricultural land.
The age of a forest can influence how effectively it offsets our emissions.
Tree planting projects that use non-native trees risk releasing more carbon back into the atmosphere, undermining efforts to fight climate change.
Governments are throwing billions of taxpayer dollars on stimulus measures after COVID-19. But they must do it diligently, and transparently.
New Zealand is pumping millions of dollars into environment projects as part of its COVID-19 recovery. Australia’s recovery plan seems more destructive than reconstructive.
During California’s deadliest wildfire season, 2,000 prison inmates fought the flames on USD$1 a day.
Inner Melbourne alone has lost 2,000 street trees to major developments within a decade. Losing tree cover makes it even more difficult for our cities to cope with an increasingly tough climate.
Although China’s tree-planting efforts have increased carbon sequestration for climate mitigation and protected the soil from erosion, they have also led to drastic water shortages.
The UK’s official climate advisor recommends up to 50,000 hectares of new woodland each year by 2050.
Promising to plant 100m trees a year is one thing; making them grow can be quite another.
John Evelyn’s 1664 work ‘Sylva’ called for a mass tree planting campaign.
Ecological literacy is needed to guide global tree planting initiatives to avoid damaging some ecosystems.
Thirty tree species make up more than half of Australia’s urban forests. Some won’t survive climate change, so cities must plant a more diverse mix of the right species to preserve their tree cover.
