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.

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.

It is one of the global problems targeted under the Sustainable Development Goals (SDG 15). The aim of this article is to review the history of desertification and to evaluate the scientific evidence for desertification spread and severity. First quantitative estimates of the global extent and severity of desertification were dramatic and resulted in the establishment of the UN Convention to Combat Desertification (UNCCD) in 1994. UNCCD’s task is to mitigate the negative impacts of desertification in drylands.

Feed and grazing management affect both the quantity and quality of animal manure and consequently nutrient cycling in the mixed crop-livestock systems in West Africa Sahel. Dietary measures can significantly influence the composition of manure and hence it’s agricultural value. High nutrient feed will generally result in higher nutrient content of the manure whereas a decline in feed quality will generally lead to increase in the indigestible fractions in the feeds.

Tetra Tech’s land tenure and property rights experts examine how weak land and resource governance can fuel drivers of violent extremism. With a focus on the African Sahel, this new issue brief finds this dynamic is especially prevalent when land and resource governance challenges are coupled with environmental disruptions, resource scarcity, or migration.

Pastoral livestock production is crucial to the livelihoods and the economy of Africa’s semiarid regions. It developed 7,000 years ago in response to long-tern climate change. It spread throughout Northern Africa as an adaptation to the rapidly changing and increasingly unpredictable arid climate. It is practiced in an area representing 43% of Africa’s land mass in the different regions of Africa, and in some regions it represents the dominant livelihoods system.

In many countries, pastoralism has historically been practiced in areas that are now partitioned by international boundaries. This is a major barrier to sustainable resource management and to pastoral development. However, there are examples from around the world of efforts to facilitate transboundary movements and transboundary ecosystem management by pastoralists. This report examines how pastoral mobility has been impacted by the creation of unnatural boundaries within their landscapes and how societies cope with these constraints through legal or informal arrangements.
