Knowledge transfer depends on the motivations of the target users. A case study of the intention of Indonesian coffee farmers to use a tree canopy trimming technique in pine–based agroforestry highlights path-dependency and complexity of social-ecological relationships. Farmers have contracts permitting coffee cultivation under pine trees owned by the state forestry company but have no right to fell trees.

By declaring the Decade on Ecosystem Restoration, the UN has recognized that there are only 10 years left to restore the world's degraded land. Countries are striving to fight climate change by 2030 through their Paris Agreement commitments and the Sustainable Development Goals (SDGs). But in many cases, their climate and development agenda are disconnected, even though sustainability and development go hand in hand – especially for rural communities. The divide is particularly severe when it comes to restoring degraded land.

In a world grappling with the challenges of food insecurity, climate change, landscape degradation, and rural poverty, regreening offers a path forward, especially in dryland areas. The transformation of degraded landscapes—restoring productivity and increasing resilience through the widespread adoption of agroforestry and sustainable land management practices—can deliver food, climate, and livelihood benefits.

These guidelines have been developed based on FAO’s and WOCAT’s extensive experience. The book draws, in particular, on WOCAT’s network and its database of SLM knowledge - as well as on WOC AT’s first overview book entitled ‘Where the land is greener’. These guidelines were implemented in the framework of the TerrAfrica partnership, whose main objective is to mainstream and upscale SLM in SSA, through the leveraging and harmonising of multisectoral investments at the local, country, subregional and regional levels.

Valuable lessons can be learned from smallholder farmers who have successfully protected and regenerated tree cover across agricultural landscapes in Senegal, with minimal reliance on tree nurseries, seedling distribution or tree planting. In the process, they have restored soil fertility to sustainably increase agricultural production.

In the above initiatives, self-motivated populations increased food security and reduced vulnerabilities to climatic shocks by restoring and sustainably managing local forest resources. To regenerate agroforestry parklands, farmers built on traditional systems to increase on-farm tree density and convert degraded lands to densely wooded savannas. These actions increased crop yields and produced new sources of livestock browse. The population of Sambandé restored the local forest and managed it to sustainably produce fuel and fruit.

‘Over the past three decades hundreds of thousands of farmers in Burkina Faso and Niger, on the fringes of the Sahara Desert, have transformed large swathes of the region’s arid landscape into productive agricultural land, improving food security for about three million people. Once-denuded landscapes are now home to abundant trees, crops, and livestock.'
