Hydrologic effects on rangeland degradation and restoration processesacteristics and rain use efficiency. The degree to which these hydrologic attributes are affected by land use determines the impact of the land use on the ecosystem. Simply removing the initial cause of degradation may not restore the site’s production potential, and may not even break the pattern o

Assessing and monitoring desertification with soil indicatorsssess desertification in rangelands. The procedure is entirely field-based, using indicators of surface processes to infer the status of landscape on a function/dysfunction continuum. The first step is to identify, map and measure zones of resource loss (run-off) and resource gain (run-on) in the la

Agricultural and ecological perspectives of vegetation dynamics and desertificationsurement of degradation and management application. The first view embodies an agricultural perspective developed from a lengthy research programme in the relatively unpredictable Nama-karoo biome of South Africa. The guiding theoretical principle within agricultural research borrows heavily from Cl

The United Nations data bases on desertificationlobal Assessment of Human-Induced Soil Degradation (GLASOD). New assessments have been carried out regionally in Asia and at national level in a number of other countries. Based on these, a new, extensively revised edition of the World Atlas of Desertification was published by UNEP in 1997. Work con

Evolution of rangeland conservation strategiesand community involvement. In this paper, the long history of combating desertification in Iceland is used to illustrate past, present and future perspectives in the implementation of rangeland conservation programs..Livestock production based on grazing of rangelands has been the mainstay of Icelan
