Report - global deserts outlook


The Global Deserts Outlook is the first thematic assessment report in the Global Environment Outlook (GEO) series of the United Nations Environment Programme (UNEP). A UNEP contribution to the International Year of Deserts and Desertification in 2006, the report aims to help raise global public awareness of the state of the world’s deserts.

The Global Deserts Outlook presents a panorama of the environmental status of the world’s deserts: their location and extent, uniqueness and vulnerability, biodiversity and natural resources. The report provides a balanced picture of deserts as ecosystems which form a special part of the world’s natural and cultural heritage, and not simply as land that is the end result of the process of desertification. Few places on earth contain a richer collection of natural adaptations to the environment.

GLOBIO contribution

The SRES A2 scenario is analysed for its consequences on biodiversity. Results of both the GLOBIO2 and the GLOBIO3 model version are presented, using the human impact indicator from GLOBIO2, changes in extent of deserts and the Mean Species Abundance indicator.
