    On a global scale, Sudan perhaps ranks first in terms of pastoralists population size. About
    66 per cent of Sudan is arid land, which is mainly pastoralists’ habitat. Pastoralism in the
    Sudan involves about 20 per cent of the population and accounts for almost 40 per cent of
    livestock wealth [Markakis, 1998: 41]. The livestock sector plays an important role in the
    economy of the Sudan, accounting for about 20 percent of the GDP, meeting the domestic
    demand for meat and about 70 percent of national milk requirements and contributing about

    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.

    Desertification is defined as land degradation occurring in the global drylands. 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.

    The year 2002 marked ICARDA's 25th anniversary, and coincided with several honors and awards for the center's excellence in research. Research on developing high-yielding kabuli chickpea varieties that thrive in cool, wet winter conditions earned the 2002 King Baudouin Award of the Consultative Group on International Agricultural Research (CGIAR), jointly with the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), which focuses on desi chickpea.

    Few regions present bigger development challenges than the African drylands – home to nearly 300 million people, and the vast majority of Africa’s poor. Food security and rural welfare in these areas are limited by a range of factors, biophysical, socio-economic and policy-related. And many of the biggest challenges – poverty, drought, land degradation, food insecurity – will be exacerbated by climate change.

    Widespread heat waves, floods, and droughts last year were a strong reminder of the threats posed by climate change. In the non-tropical dry areas where ICARDA works we are becoming accustomed to record high temperatures and increasing water scarcity year on year. Resilience and climate change adaptation are at the heart of ICARDA’s new Strategic Plan 2017-2026 – a bold and ambitious effort to harness cutting-edge science and deliver the tools and technologies that smallholder farmers need to maintain agricultural production and protect their livelihoods.
