The multiple benefits of restoration, from local to global scales, are reflected in the array of global and regional goals for restoration.

‘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.'

Global strategies to halt the dual crises of biodiversity loss and climate change are often formulated separately, even though they are interdependent and risk failure if pursued in isolation. The Global Safety Net maps how expanded nature conservation addresses both overarching threats.

The Sustainable Development Goals (SDGs) were conceived at the United Nations Conference on Sustainable Development, held in Rio de Janeiro in 2012 (Rio + 20), and adopted by the United Nations General Assembly in September 2015. They are part of a larger framework, namely the UN 2030 Agenda for Sustainable Development.

The West African Sahel is very vulnerable to the effects of climate change, due to land degradation, dependence on rainfed farming, political instability, poor governance, food insecurity, terrorism, poor infrastructure, and limited technical capacity. This has particular impacts on the agricultural sector (Sissoko et al. 2011; Zougmoré et al. 2016).

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.

Unless countries can manage to mobilize millions of land users to invest their scarce resources in protecting regenerating trees, the battle against land degradation cannot be won. These experiences from Niger show that hundreds of thousands of smallholder farm families have substantially increased tree cover on their farm land by investing in the management of on-farm trees.

The climate-smart village approach created enthusiasm and commitment from farmers in seeking solutions to the problems and constraints that they themselves identified. The approach also involved strengthening the capacity of technical staff to use new tools, and to understand and support the new methods, with complementary finance to support the changes.

When the IFAD-funded project started in 1988, few people could have imagined that 15 years later the degraded plateaus would be covered with trees on land restored to production by individual smallholder farmers.

Key success factors
There were several reasons for the success of the restoration initiative.
• Implementation had the active participation of the local community; i.e., it was community- led restoration.
• Restoration produced short- and long-term economic and environmental benefits.
• It systematically included women, girls and youth in restoration activities.

Since the mid-1980s, the positive impacts of these simple, cost-efficient water harvesting techniques become clear, following their increasingly widespread adoption. Their use has allowed smallholders to reverse land degradation, improve soil fertility, sustainably increase crop production, achieve food security, and create more productive, diverse and resilient farming systems.
