Land reclamation has played a significant role in the urban development process in coastal areas in many countries. Over the last 20 years, land reclamation has gained much popularity especially along coastal areas of the south and east China due to rapid development of industry and urbanization. While reclamation provides valuable land, it also creates various engineering, environmental and ec...

Land degradation is becoming one of the severest environmental issues in the world, especially in developing nations. Land degradation, usually accompanied by soil erosion, always results in a decrease or complete loss of land productivity, and produces on-site and off-site pollution to soil and water. The methods for land reclamation are various, including physical, chemical and biological. Th...

Surface coal mining in Appalachia has caused extensive replacement of forest with non-forested land cover, much of which is unmanaged and unproductive. Although forested ecosystems are valued by society for both marketable products and ecosystem services, forests have not been restored on most Appalachian mined lands because traditional reclamation practices, encouraged by regulatory policies, ...

Reclamation of abandoned farmland is crucial to a sustainable agriculture in arid regions. This study aims to evaluate the impact of different reclamation treatments on abandoned salinized farmland. We investigated four artificial reclamation treatments, continuous cotton (CC), continuous alfalfa (CA), tree-wheat intercropping (TW) and trees (TS), which were conducted in 2011–2012 in the Manasi...

The Mid-eastern Inner Mongolia of China, a typical agro-pastoral transitional zone, has undergone rapid agricultural land use changes including land reclamation and cropland abandonment in past decades due to growing population and food demand, climatic variability, and land use policy such as the "Grain for Green" Project (GFG Project). It is significant to the regional ecology and sustainabil...

In this paper the reclamation and reuse of municipal secondary effluents, as well as the reclamation and recycling of refinery secondary effluents, are technically and economically evaluated. It is shown that both practices are feasible and sustainable, and that the reclamation costs depend largely on specific circumstances such as legal requirements, price policy, reuse application, raw water ...

a r t i c l e i n f o Land has been reclaimed along the coastal areas in many parts of the world to meet the growing demand for houses and other land use. Over 15 km 2 of land has been reclaimed around the Shekou peninsula, Shenzhen, China. Land reclamation may have significant influences on groundwater systems but this problem has not been adequately studied. Using FEFLOW (Diersch, 2005), a th...

Coal resource is the main primary energy in our country, while Shanxi Province is the most important province in resource. Therefore Shanxi is an energy base for our country and has a great significance in energy strategy. However because of the heavy development of the coal resource, the ecological environment is worsening and the farmland is reducing continuously in Shanxi Province. How to re...

This study reports on the use of a substrate-reclamation technology for a gallium nitride (GaN)-based lighting-emitting diode (LED) wafer. There are many ways to reclaim sapphire substrates of scrap LED wafers. Compared with a common substrate-reclamation method based on chemical mechanical polishing, this research technology exhibits simple process procedures, without impairing the surface mor...

Unlike green sand, chemically bonded sand cannot be used again and again without reclamation because in this system, the mixed sand gets it`s strength through chemical reaction which is irreversible in nature. Each sand particle is coated with this reacted chemical, which behaves like an inert element after usage once. This inert coating also called “Dead” binder needs to be removed from the us...
