The issues of land degradation are directly or indirectly influenced by human and/or natural actions, and it is one the most challenging confronting several regions world, especially developing nations. Notwithstanding importance land, its consequences, possibly as a result various biological, physical, chemical processes caused some activities (both man-induced) that diminish viable yield, in ...

Cultivated land in China has faced severe challenges in recent years due to rapid urbanization. In 1997, the “cultivated land requisition-compensation balance” policy was implemented by the government to maintain the quantity and quality of cultivated land. Previous studies mainly focused on the quantity changes of cultivated land. In this study, from a quality perspective, we characterized the...

New ports are mostly constructed on low lying coastal areas or shallow coastal waters. The quay wall and terminal yard are raised to a level well above mean sea level to assure flood safety. The resulting ‘conventional terminal’ requires large volumes of fill material often dredged from the sea, which is costly. The terminal yard of a ‘polder terminal’ lies below the outside water level and is ...

Rapid urbanization on the coast of China has attracted much attention. The objective of this study was to explore the differences in dynamics and related driving forces between urban and rural settlements. Applying the quantitative method, we demonstrate that substantial heterogeneity in settlement growth, landscape pattern metrics, change, land sources and driving forces is exhibited across th...

This study aims to determine the accuracy level at which different forms of land degradation can be mapped from medium-resolution satellite data, and to assess how accurately degraded land can be detected from multi-temporal satellite images. Land degradation in the form of salinization and waterlogging in Tongyu County, western Jilin Province of Northeast China was mapped from Landsat TM and A...

Faunal diversity is an indicator of soil amelioration. Estimating the population size or density of an animal species in an area is fundamental to understand its status and demography and to plan for its management and conservation. Considering this, faunal diversity in reclamed sodic land was monitored during rainy season 2000-01 at different locations of district viz., Aligarh, Etah, Fatehpur...

While participatory design in IS has found increasing acceptance, the role of participation in social arena has been lively debated in recent years. Development projects in the third world based on “western” assumptions have elicited sharp critiques, with consequent policy shift towards involving the poor people and local communities in these endeavours. In India, policies and programs aimed at...
