Key messages

• Drylands cover 6.1 billion hectares, making up 41 % of the Earth’s land surface, characterized by water scarcity. They cover more than 100 countries across regions and are the basis for livelihoods of more than 2 billion people.
• Trees and forests in drylands generate a wealth of environmental services, they provide habitats for biodiversity, protect against water and wind erosion and desertification, help water infiltrate soils and contribute to soil fertility.
• Trees and forests in drylands help increase the resilience of landscapes and communities in the face of climate change.
• Drylands contain 1.11 billion hectares of forests (18% of the global drylands area and 27% of the global forest area), 1.8 billion of grasslands (31% of the global dryland area), 0.86 billion hectares of cropland (14% of the global dryland area). 
• Trees are present on 1.9 billion ha of the world’s drylands.
• Land degradation in drylands, commonly referred to as desertification, almost always begins with the removal and degradation of vegetation including forests and grasslands.
• In Africa, drylands (arid, semi-arid and dry sub-humid) comprise 43 % of the continent’s land area, and are inhabited by farmers, herders and pastoralists whose livelihoods heavily depend on the goods and services provided by forests, trees, shrublands, farmlands, and grazing lands.
• The long-term sustainability of dryland forests is in jeopardy due to population increase, growing demand for natural resources, poverty, social conflicts, lack of market opportunities and technical capacity, lack of appropriate policies, governance and investments and lack of integration among different sectors.
• Climate change affects dryland forests and people as it exacerbates all these negative human-related factors.

Trees, forests and land use in drylands: The first global assessment Drylands cover about 41 percent of the Earth’s land surface and are characterized by a scarcity of water (Box 1 contains a full definition). About 90 percent of the estimated 2 billion people living in drylands are in developing countries (Millennium Ecosystem Assessment, 2005). The majority of these people depend on forests and other wooded lands, grasslands and trees on farms to meet basic needs for food, medicines, shelter, cooking, heating, wood, and fodder for livestock, and for income.

Global guidelines for the restoration of degraded forests and landscapes in drylands Drylands cover nearly half of the earth’s land surface and are home to one-third of the global population. They face extraordinary challenges, including those posed by desertification, biodiversity loss, poverty, food insecurity and climate change. It is clear that serious efforts are needed to arrest dryland degradation and restore degraded lands, and the simple but urgent aim of these guidelines is to support such efforts. [more]

State of Mediterranean Forests 2018 The State of Mediterranean Forests 2018 analyzes the circum-Mediterranean region, a territoryencompassing thirty-one countries and a wide range of political, economic, social and environmentalcontexts. Today, human activity has placed substantial pressure on this environment, the impact of which is feltdifferently in the northern, southern and eastern sub-regions. [more]

Agroecology a viable solution to vulnerable Sahel Highly-vulnerable communities in the Sahel has agroecology as a mechanism to stem the rise of hunger and malnutrition in a region buffeted by increased pressure on natural resources including soils and water, the loss of biodiversity, and the uncertainties associated with climate change. [more]

Solving land degradation hinges on economic development Rural communities in Africa’s drylands can earn a decent income from forest products such as gum arabic or tree oils. According to a new report from Action Against Desertification, rural populations have the opportunity to increase their incomes while reversing land degradation through sufficient support and investment, and developing value chains.
