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...

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...

land degradation, or desertification, is specific to arid, semi-arid, and dry sub-humid regions. the rate of thisphenomenon is high in developing countries such as iran. this research investigated desertification and mapping ofdesertification in abuzaydabad, near kashan, iran, with an emphasis on land criteria using an imdpa model.different studies have assessed land degradation or desertificat...

Desertification is a major environmental problem facing the world today, and climate change an important factor influencing desertification. This study investigates impact of changes in key factors on desertification based normalized difference vegetation index data, precipitation data evaporation from Inner Mongolia between 1982 2020 using correlation analysis, regression modelling, residual a...

a r t i c l e i n f o Land degradation in drylands is one of the major environmental issues of the 21st century particularly due to its impact on world food security and environmental quality. Climate change, shifts in vegetation composition, accelerated soil erosion processes, and disturbances have rendered these landscapes susceptible to rapid degradation that has important feedbacks on regio...

desertification is more related to social and anthropogenic issues than natural causes and it becomes moreimportant over the time. human effects on desertification could be classified as direct and indirect factors. this studyhas focused on the effect of management factor, as a dominant case, on desertification of kashan region based onimdpa (imdpa: iranian model of desertification for potentia...

desertification is one of the major issues threatening human communities. manymethods have been developed for assessment and mapping of desertification hazards. in thisresearch, multi-criteria evaluation method was used to investigate desertification process introuti watershed, golestan province, iran. at the first step, major desertification factors weredetermined by doing field surveys. they ...
