The Global Drylands Observing System proposed in this issue should reduce the huge uncertainty about the extent of desertification and the rate at which it is changing, and provide valuable information to scientists, planners and policy-makers. However, it needs careful design if information outputs are to be scientifically credible and salient to the needs of people living in dry areas. Its de...

Many assumptions have been made about the nature and character of desertification in West Africa. This paper examines the history of this issue, reviews the current state of our knowledge concerning the meteorological aspects of desertification, and presents the results of a select group of analyses related to this question. The common notion of desertification is of an advancing “desert,” a ge...

Embedded in a larger qualitative research framework on organizational effectiveness, this paper explores the role of small treaty secretariats—conceptualised as a distinct type of intergovernmental organizations—in international politics. Although the relevance of bureaucratic actors in international negotiations and regime implementation has been acknowledged by a number of scholars, IR resear...

1. Desertification negatively impacts a large proportion of the global human population and > 30% of the terrestrial land surface. Better methods are needed to detect areas that are at risk of desertification and to ameliorate desertified areas. Biological soil crusts are an important soil lichen-moss-microbial community that can be used toward these goals, as (i) bioindicators of desertificati...

Desertification due to climate change and increasing drought periods is a worldwide problem for both ecology and economy. Our ability to understand how vegetation manages to survive and propagate through arid and semiarid ecosystems may be useful in the development of future strategies to prevent desertification, preserve flora-and fauna within-or even make use of scarce resources soils. In thi...

This paper aims to present an integrated approach for assessing the desertification processes on one hand and spot possible source locations of dust storm in Eurasian continent across the central Asia and northern China on the other hand. The authors have bu ilt Remote Sensing Environmental Monitor (RSEM) for Desertification Assessment System (DAS). Such an integrated sensing, monitoring and mo...

The municipality Santa Filomena that it was for is included in the Nucleus of Desertification Gilbués, since all other municipalities are part same nucleus are. Data from IBGE Demographic Census (2010) and GDP published by (2009) were used. Social indicators exclusion education income sought. In addition to being reduced, far ideal a good quality life.

Overgrazing plays an important role in the grassland desertification global drylands. The effectiveness of policies related to grazing directly affects efforts combat and sustainable rangeland management. However, there remain questions around how interplay poverty implementation policies. To reveal prevention policy that delineates national key ecological function areas (NKEFAs), main objectiv...

Desertification is one of the phenomena that threatening environmental, economic, and social systems. This study aims to evaluate monitor desertification in central parts Iraq between Tigris Euphrates rivers through use remote sensing techniques geographic information The Normalized difference vegetation index NDVI crust CI were used, which applied two Landsat ETM + OLI satellite imagery during...
