Question 1) What is the UN Restoration Decade?
- Aiming to counter different environmental emergencies and rehabilitate degraded landscapes, the UN launched the decade on ecosystem restoration in 2021.1
Question 3) True or False? Trees are the plant species most suited to restore any given landscape under any circumstance.
- Although trees are an excellent way to sequester carbon dioxide, they may not always be the first nor only choice to restore certain environments. Some environments may not naturally support trees, so other plant species should be considered. Bamboo, for instance, can regenerate bare land quickly.3
- Forests grow and mature slowly, and making sure restored forests will survive for decades is key to maximizing the social and ecological benefits they provide.4
Question 7) True or False? Degraded farmlands cannot be restored.
- Degraded farmlands can, and must, be restored. Luckily, many techniques can facilitate that.2
Question 8) Some big restoration projects fail because they did not make smart planting choices. Out of the 50 million seedlings planted in Northern Nigeria, how many have withered and died within two months?
- Those seedlings were planted in extremely dry areas, causing the local population to compete with trees for water.7
Question 9) What aspects should be considered for a successful ecosystem restoration program?
- It is fundamental that restoration programs respect the local culture and knowledge, empower local communities, care for trees instead of just planting them, and focus on quality rather than quantity.2
Question 10) How many trees should be grown so that the world meets the target set by the UN Decade on Ecosystem Restoration? Remember… Although tree growing is not the only strategy to ensure restoration, these plant species play a big role in this global effort!
- The UN Decade on Ecosystem Restoration has set the ambitious target of planting 3 trillion trees across the world by the year 2030.2
