Erosion models: use and misuse on rangelandsal desertification issues, erosion modeling must move beyond general or simplistic long-term erosion estimates. Future erosion models must be usable in an ecological context and address “state and transition” and “threshold” concepts and principles.

暫停,間歇

Scaling up from field measurements to large areas using the Desertification Response Unit and Indica ecosystem health are highly appropriate for studying desertification, but they can not be applied uniformly. Rather, they must be applied within the framework of a typology of land units within which the responses to change are similar.

Rangelands issues and trends in developing countriese of promising ideas and practices in some developing countries. These include improved democracy and governance, bottom-up approaches and integration of multi sectoral actions.
