It is our great honor to edit this special issue of Environmental Geochemistry and Health (EGAH), especially with the special theme of mine reclamation and suitable management for heavy metals. This issue has been made up with the extended works of oral or poster presentations that were given at the 2009 International Symposium on Mine Reclamation held cooperatively by the Korea Mine Reclamatio...

I build a model that explains Midwestern US maize and soybean yield as a function of weather and soil capability. Climate change is expected to reduce mid-century maize and soybean yields in the Midwest by 8% to 28% and 7% to 23%, respectively, depending on cropped land’s soil capability and severity of climate change, compared to baseline values calculated with no climate change. I find that s...

Large-scale reclamation projects during the past decades have been recognized as one of the driving factors behind land subsidence in coastal areas. However, the pattern of temporal evolution in reclamation settlements has rarely been analyzed. In this work, we study the spatio-temporal evolution pattern of Linggang New City (LNC) in Shanghai, China, using space-borne synthetic aperture radar i...

Monitoring of reclaimed sites is a complex, interdisciplinary undertaking, especially in large, disturbed areas with difficult access. In that context, remote sensing is a unique and valuable tool that provides a synoptic view of an entire reclamation program and its progress over time, extending the more detailed but sparsely distributed in situ monitoring. Using remote sensing data, we are cr...

Land reclamation in Penang began two decades ago and is still rampant with large reclamation projects planned to be executed in the near future. The present study provides the first information on effects of land reclamation in Penang towards the coastal macroinvertebrates. This study assessed the abundance, diversity, and evenness of coastal invertebrates assumed to be the foremost affected wh...

In western United States, both mine reclamations and renewed mining at previously abandoned mines have increased substantially in the last decade. This increased activity may adversely impact bats that use these mines for roosting. Townsend’s big-eared bat (Corynorhinus townsendii) is a species of conservation concern that may be impacted by ongoing mine reclamation and renewedmineral extractio...

During oil-sands mining all vegetation, soil, overburden, and oil sand is removed, leaving pits several kilometers wide and up to 100 m deep. These pits are reclaimed through a variety of treatments using subsoil or a mixed peat-mineral soil cap. Using nonmetric multidimensional scaling and cluster analysis of measurements of ecosystem function, reclamation treatments of several age classes wer...

protecting the environment is becoming one of the most important concerns of the developed and developing countries. reclamation of msw landfills, which are sources of many pollutants including leachate and greenhouse gases, would be very valuable in saving the resources and reducing the pollution scale. in the current article the potential for use of reclaimed waste in rdf production has been ...

Re-enchantment and Reclamation is a two-year research project, begun in 2006, involving four artists based at Lancaster University UK, who are collaborating with four artists from the UK and abroad. Through a programme of workshops and lectures the project aims to discover and develop methods in dance, film, and the sonic arts for re-enchanting and reclaiming the landscape of Morecambe Bay in t...
