Can the Great Green Wall deliver more than trees? A rapid review of the potential multidimensional impacts of trees in the Sahel.

• The Great Green Wall (GGW) is focused on land restoration through tree planting and natural regeneration across 8,000km of the Sahel.
• Impacts to-date include land restoration on 4m hectares of the official target zone and an additional 14m ha across the target region. USD 90m in revenue has also been generated.
• The GGW has the potential to contribute to global goals related to climate mitigation, ecological resilience, improved human health and wellbeing, and equity and empowerment.
• Ensuring and building upon the varied impacts of GGW activities will require specific attention to monitoring and evaluation approaches and activities.
