    Natural rangelands occupy about 5.5 million hectares of Tunisia’s landmass, and 38% of this area is in Tataouine governorate. Although efforts towards natural restoration are increasing rapidly as a result of restoration projects, the area of degraded rangelands has continued to expand and the severity of desertification has continued to intensify. Any damage caused by disturbances, such as grazing and recurrent drought, may be masked by a return of favorable rainfall conditions.

    FOOD SYSTEMS ARE EVOLVING QUICKLY TO MEET GROWING AND CHANGING DEMAND, BUT THEY ARE NOT SERVING EVERYONE’S NEEDS. As we modernize food systems to make them climate-smart, healthy, and sustainable, we must also strive to make them inclusive of smallholders, youth, women, conflict-affected people, and other poor and marginalized people.

    Dust storms are capable of transporting sediment over thousands of kilometers, but due to the Middle East and North Africa (MENA) region’s proximity to the Sahara Desert, the region is one of the dustiest in the world. While natural sources such as the Sahara are the main contributors to dust storms in MENA, land-use changes and human-induced climate change has added anthropogenic sources as well.

    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.

    ‘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.'

    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.

    States of ecological maturity and temporal trends of drylands in Morocco, Algeria and Tunisia north of 28 N are reported for 1998–2008. The input data were Normalized Difference Vegetation Index databases and corresponding climate fields, at a spatial resolution of 1 km and a temporal resolution of one month. States convey opposing dynamics of human exploitation and ecological succession. They were identified synchronically for the full period by comparing each location to all other locations in the study area under equivalent aridity.

    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.
