    Located in the arid and semi-arid areas of West Africa, the Sahel has undergone profound changes over the past 50 years. Known for the prevalence of land degradation processes, the Sahel is suffering from the combined negative effects of population growth, human activities and climate variability, resulting in recurrent droughts and the continued decline of natural resources and land productivity.

    It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. Looking beyond the Sahel, the chapters in this book provide case studies from around the world that examine the use and relevance of the desertification concept.

    The support plan for the Sahel is a regional approach to collectively address the root causes of disruptions such as poverty, migration and youth unemployment, climate change, insecurity, governance and institutional issues in the region. In this report an overview of the current situation for each of the priority areas of the UN Support Plan is presented to demonstrate that the full implementation of the plan could utilize an existing momentum of development not seen in decades in the Sahel.

    The United Nations General Assembly declared 2021 to 2030 as the decade of ‘ecosystem restoration’, signalling a global consensus on the urgency to restore degraded lands. Restoring degraded lands is critical to regain lost ecological functionality that underpins life-sustaining ecosystem services, such as the provision of food, fresh water, and fibre, and the regulation of climate, natural disasters, and pests. Indeed, restoration is fundamental for meeting the triple goals of tackling the climate crisis, reversing biodiversity loss, and improving human wellbeing.

    Drylands occupy more than 40% of the world’s land area and are home to some two billion people. This includes a disproportionate number of the world’s poorest people, who live in degraded and severely degraded landscapes. The United Nations Convention to Combat Desertification states on its website that 12 million hectares are lost annually to desertification and drought, and that more than 1.5 billion people are directly dependent on land that is being degraded, leading to US$42 billion in lost earnings each year.

    ‘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.'

    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.

    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.
