Abstract

In this millennium, global drylands face a myriad of problems that present tough research, management, and policy challenges. Recent advances in dryland development, however, together with the integrative approaches of global change and sustainability science, suggest that concerns about land degradation, poverty, safeguarding biodiversity, and protecting the culture of 2.5 billion people can be confronted with renewed optimism. We review recent lessons about the functioning of dryland ecosystems and the livelihood systems of their human residents and introduce a new synthetic framework, the Drylands Development Paradigm (DDP). The DDP, supported by a growing and well-documented set of tools for policy and management action, helps navigate the inherent complexity of desertification and dryland development, identifying and synthesizing those factors important to research, management, and policy communities.

4. The precise numbers of the dryland population affected by desertification is contentious ( 50 ) but 250 million is a widely cited approximation ( 2 3 ). For comparison the Global Fund estimates annually 1 million deaths and 300 to 500 million new infections for malaria 3 million deaths and 40 million new infections for AIDS/HIV and 2 million deaths and 8 million new infections for tuberculosis (www.theglobalfund.org).

5. There has been extensive debate concerning definitions of desertification and degradation ( 51 ). Although the CCD definition is now formalized internationally a summary of the debate is given in ( 10 52 ).
