‘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.'

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.

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.

Land Degradation Neutrality is a new way of approaching land degradation that acknowledges that land and land-based ecosystems are affected by global environmental change as well as by local land use practices. Achieving the target of a land degradation neutral world encourages adaptive management during planning, implementation, and monitoring of LDN-related activities and follows the LDN response hierarchy of avoiding, reducing, and reversing land degradation.

Agriculture influences and shapes the world’s ecosystems, but not always in a positive way. More than 2.5 billion people are globally involved as stewards of land and water ecosystems that constitute the natural resource base for feeding the current and future world population. Yet, conventional agronomic interventions based on ‘hard’ agricultural engineering compromise various eco-services that are required for sustainable agricultural development.

Land degradation is increasingly recognised as global challenge and is even pushed for as candidate for a (post-2015) Sustainable Development Goal (SDG). The ‘quality of soil’ has been linked to the emergence of conflict, inter alia since it aggravates food and water scarcity. It is an underestimated, but essential element in the nexus of global challenges related to food, water and energy. This Clingendael Report, finds, amongst others, that accurate assessments on land degradation and efforts to restore lands are still lacking to date.

Countries of the Near East, North Africa, Europe and Central Asia (NEN) region face a myriad of social, economic and political challenges that have stalled their structural and rural transformation processes. This has had a detrimental impacton rural youth, who, as a result, face limited economic opportunities. The NEN region has the highest youth unemployment rates in the world. Weak education systems are failing to provide youth, especially in rural areas, with the cognitive and non-cognitive skills they need to compete in a global economy.

Satellites provide the possibility to give a synoptical view of the earth surface at regular time intervals. Satellites operating in the optical wavelengths have however as disadvantage that monitoring of the surface characteristics becomes impossible as soon as clouds are present. Deserts and desert margins are for that reason much more appropriate for monitoring by optical satellites than temperate and wet tropical areas. Potential hazards, possibilities and often inaccessibility makes use of optical remote sensing very reasonable.

The New Urban Agenda and SDG 11 promote inclusive urban development, but limited empirical knowledge exists on how such global rhetoric plays out on the ground. This paper contributes to the inclusive city debate by focusing on the case of Soba, a peri‐urban area at the fringes of the capital of Sudan. Based on an explorative study of secondary material, semi‐structured interviews and structured observations it aims to systematically analyse the dynamics of peri‐urban development.
