Abstract Ecological stoichiometry facilitates the understanding of biogeochemical cycles by studying balance among multiple elements in ecosystems. However, spatial patterns soil and their responses to land use desertified are unclear. In this study, we selected 525 sample points collect topsoil (0–20 cm) samples throughout China's Horqin Sandy Land measured organic carbon (SOC), total nitrogen...

In this paper, the spatial distribution of stony desertification characteristics and its influencing factors in Karst areas in different sampling scales are studied using a grid sampling method based on geographic information system (GIS) technology and geo-statistics, with the rock bareness rate obtained through sampling with 150m × 150m grids in the Houzhai River Basin being taken as the orig...

Demands are increasing for scientific research to be explicitly and demonstrably policy relevant. Research funders are requiring greater returns on their investments and scientists are expected to demonstrate clearly how their research can inform policy and regulation to deliver positive consequences for societal, economic and environmental wellbeing. Within the co-evolving context of environme...

Land cover changes influence the biogeochemistry, hydrology, and climate of the earth. Studies that assessed land cover changes at the global scale mostly focused on: deforestation, cropland expansion, dry land degradation, urbanisation, pasture expansion, and agricultural intensification. For the assessment, remotely sensed land-cover data, census data, and expert knowledge were used. In tropi...

Degradation of semi-arid and arid ecosystems due to desertification is arguably one of the main obstacles for sustainability in those regions. In recent decades, the Mu Us Desert in China has experienced such ecological degradation making quantification of spatial patterns of desertification in this area an important research topic. We analyzed desertification dynamics for seven periods from 19...

Taken as a classical issue in applied economics, the notion of ‘convergence’ is based on concept path dependence, i.e., from previous trajectory undertaken by system during its recent history. Going beyond social science, perspective has been more recently adopted environmental studies. Spatial convergence non-linear processes, such desertification risk, meaningful since represents (possibly un...

Land-cover change is regarded as the most important global change affecting ecological systems (Vitousek, 1994). Natural landscapes – i.e. those largely unaffected or hardly affected by human activities – are being rapidly transformed into urban and farmland landscapes throughout the world (Foley et al., 2005; Feranec et al., 2010; López and Sierra, 2010). As the characteristics of land-cover h...

the present study illustrates the long-term changes in selected socioeconomic variables (population,industrial activities, settlement dispersion, and land-use) together with climate aridity trends in thriasio, the larger industrial area of greece located twenty kilometers far from athens. this region, originally devoted to agriculture, experienced fast industrial and economic development during...
