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.

Around 2.5 billion people – 30 percent of the world’s population – live in the dry areas, which cover more than 40 percent of the world’s land surface. Scarce natural resources, land degradation and frequent droughts severely challenge food production in these areas. Both North Africa (Morocco, Algeria, Tunisia) and the North East of Brazil fall under arid and semi-arid climate. Cacti have developed phenological, physiological and structural adaptations for growth and survival in arid environments where they have multiple functions (food, feed, soil conservation, etc.).

For over a decade, the globalisation of environmental, economic and social issues has induced rapid modification in agriculture and land. These changes raise the question of future extensive livestock systems in regards to the worldwide challenge to double livestock production by 2050 in ways which are safe for the environment. In order to better understand and follow modification processes, a comparative study of livestock systems and land dynamics has been carried out on seven case studies on three continents through the use of a common grid.

We propose a flexible and adaptable framework to assist the quick design of models dealing with the durability of the extensive livestock systems at the territorial scale. This metamodel results from the collaborative design starting from MAS developed on 7 sites in Latin America, France and Senegal. It is composed of four packages: Agent, Community, Space and Vegetation-Herd. We illustrate these packages with examples extracted from the various models. The role of this tool is discussed in order to show its advantages and its limits

The present study, by the Chief of the Agrarian and Water Law Section of the FAO Legislation Branch, is intended to explore in greater depth the value of legislation to the land use planning process. It is, on the one hand, an exploration of the ways in which legislation serves to provide the structural underpinnings for and connections between the technical disciplines which have long been associated with the land use planning effort.

<p>The <i>State of the World’s Forest Genetic Resources</i> addresses the conservation, management and sustainable use of forest tree and other woody plant genetic resources of actual and potential value for human well-being in the broad range of management systems. This report complements two other FAO flagship publications in the field of forestry, the annual State of the World’s Forests and the periodic Global Forest Resources Assessment (FRA).

For centuries, farmers, herders, fishers and foresters have developed diverse and locally adapted agricultural systems managed with time tested, ingenious techniques. These practices have resulted in a vital combination of social, cultural, ecological and economic services to humankind. “Globally Important Agricultural Heritage Systems” (GIAHS) are outstanding landscapes of aesthetic beauty that combine agricultural biodiversity, resilient ecosystems and a valuable cultural heritage.
