Nearly 3.2 billion people are hurt by landscape degradation
The loss of trees and forests makes the soil less healthy, less productive, reduces the available nutrients in crops, downgrades the quality of earth's water sources and threatens global biodiversity.
FORESTS + LANDSCAPES: Forest landscape restoration (FLR) is about building back lost ecosystem functions so that plants and animals, both above ground and below, are healthy and resilient. More than bringing back trees, FLR is a means to achieve many environmental goals. Center for International Forestry Research and World Agroforestry (CIFOR-ICRAF) senior scientist, Leigh Winowiecki, explains:

6 principles of FLR (2021-11-09) by FTAThe CGIAR Research Program on Forests, Trees and Agroforestry (FTA)
FTA follows 6 principles of forest landscape restoration
These principles acknowledge that forest landscape restoration (FLR) is about optimizing natural ecosystems and improving quality of life for the people who live and work in them.
FLR is holistic
The first three principles assert that FLR should focus on the entire landscape (not just forests), encourage participatory governance with all stakeholders and restore multiple ecological, social and economic functions that benefit everyone.
FLR enhances landscapes and adapts to local contexts
The next three principles of FLR state that restoration should be about sustainably managing landscapes using a diverse toolbox of approaches to fit the local context. These approaches should focus on long-term resilience for the landscapes and the people that live within them.
Restored landscapes bring back ecosystem services
As tree-cover increases or decreases due to human activities, so do the associated ecosystem services, which include clean air, water and nutrient-rich soil. This relationship is embedded in the Forest Transition Curve.
There are 3 broad categories of FLR:

1. Tree planting
Tree planting has gained popularity in the past few years with endorsements from influential people from all walks of life. From government leaders to CEOs and YouTubers, people are pledging to plant trillions of trees to save the planet.

Right tree. Right place. Right time.
Planting alone is not sufficient. However, when the right species are planted in the right place at the right time, they can be powerful tools for landscape restoration.

2. Natural regeneration
In many cases, the best approach is to sit back and let nature do its job rewilding unused or abandoned land. This allows native plants and animals to return at their own pace and create a thriving community that is perfectly suited to its environment.
Listen to CIFOR-ICRAF senior scientist, Manuel Guariguata, discuss natural landscape regeneration and important conditions for restoration success.

3. Hybrid approach
Natural restoration is not always possible for land that is constantly used for farming or has been significantly degraded. In these cases, a hybrid approach such as assisted natural regeneration (ANR), which uses some tree planting and some natural regeneration, may be best.
CASE STUDY: assisted natural regeneration (ANR) in Zambia's Miombo woodlands is helping local charcoal producers maintain their industry while also restoring the landscape.

When it's not possible to restore a whole forest...
it is still possible to bring back trees through agroforestry – planting trees on farms – or through trees in urban green spaces.

FACT or FICTION?
Test your knowledge on forest landscape restoration...
1. Tree-planting is the only way to restore degraded land.
Tree-planting is just one tool in the toolbox of restoration practices and techniques. Natural regeneration, agroforestry, rewetting peatlands and mosaic landscapes are a few other methods.
2. Forest landscape restoration is only about trees and tree-health.
Landscape restoration is about "restoring ecosystem function," so that the soil, animals, human inhabitants and trees exist together in a healthy balance.
3. FLR can help mitigate and adapt to climate change
Restored lands are rich providers of ecosystem services such as carbon storage, clean water, biodiversity and healthy soil. However, while forests and trees can help mitigate climate change, it is also essential that countries cut carbon emissions and reduce waste.
4. FLR means sacrificing farmlands for forests
Trees can be grown on farmland in ways that improve crop productivity and help restore the landscape. Trees can also grow valuable, nutritious foods that support healthy diets and increase household incomes. These practices are known as agroforestry.

When the right tree grows in the right place at the right time, forest landscape restoration benefits everyone, everywhere.
