This book is intended as a basic information kit that tells “the story” of desertification, land degradation and drought at the global scale, together with a comprehensive set of graphics. The book indicates trends as they have taken place over the last decades, combining and connecting issues, and present priorities.

The earth’s climate is changing at a rate unprecedented in recent human history and will continue to do so for the foreseeable future. The impacts and risks associated with this are global, geographically diverse and increasingly being felt across a range of systems and sectors essential for human livelihoods and well-being. The more severe and far-reaching the impacts of climate change are, the greater the loss of species will be, and the greater the deterioration of drylands and the risk of desertification and land degradation around the world will be.

The Africa–Asia Drought Risk Management Peer Assistance Project seeks to facilitate the sharing of knowledge and technical cooperation among drought-prone countries in Africa and Asia and thus to promote best practices in drought risk management (DRM) for development in the two regions. In order to establish a baseline to guide this activity, the United Nations Development Programme Drylands Development Centre (UNDP DDC) undertook a stocktaking exercise between March and June 2011 on drought impacts, causes, trends and solutions in Africa and Asia.

Les terres3 peutvent se définir comme un système destiné à générer de la productivité biologique. C’est l’infrastructure naturelle qui supporte la vie sur la planète. La quantité et la qualité de cette production dépendent du principal composant de la terre : le sol et sa fertilité. La matière organique du sol, qui provient de la végétation portée par ce dernier, est le principal composant influençant la fertilité du sol.

La tierra se define como un sistema bioproductivo. Es la infraestructura terrestre para la vida. La tasa y la calidad de la producción generada por la tierra dependen de sus principales componentes, de los suelos y de su fertilidad. La materia orgánica del suelo, derivada de la vegetación que crece en un suelo determinado, es el principal componente que controla la fertilidad de éste.

Land is defined as a system engaged in generating biological productivity. It is the earth’s infrastructure for life. The rate and quality of production generated from the land depends on its major components, soil and its fertility. Soil organic matter, derived from the vegetation supported by a particular soil, is the major component that controls soil fertility.

La terre — une ressource vitale pour la population mondiale

This brief, reviews recent international gas developments, the outlook in this regard and implications for the development of proposed offshore gas projects in Tanzania. As the country aims to benefit from its gas discoveries by increasing its domestic gas use, it also outlines some of the trade-offs and considerations that need to be taken into account when negotiating the domestic gas allocation.

Soybean production in Paraguay now takes up 80 per cent of cultivated land, displacing agricultural production by family farmers and indigenous populations and deepening inequality in access to land.

Intensive land use activities worldwide have caused considerable loss to many ecosystem services. The dynamics of these threats must be quickly investigated to ensure timely update of management strategies and policies. Compared with complex models, mapping approaches that use scoring matrices to link land use/land cover and landscape properties with ecosystem services are relatively efficient and easier to apply.

Free trade zones represent an important system innovation space to realize economic agglomeration advantages with high-level openings. However, its evaluation of land intensive use has not received enough attention. The goal of this paper is to build a land use performance evaluation index system in line with the development trend of industrial economy and the characteristics of mixed land use in the free trade zones. An evaluation index system is constructed based on the three factors of land use status, land use efficiency and pilot free trade zone influence.

Coupled with rapid urbanization and urban expansion, the spatial relationship between transportation development and land use has gained growing interest among researchers and policy makers. In this paper, a complex network model and land use intensity assessment were integrated into a spatial econometric model to explore the spatial spillover effect of the road network on intensive land use patterns in China’s Beijing–Tianjin–Hebei (BTH) urban agglomeration.
