Well-tended bamboo groves, once an integral element in the satoyama, Japan’s traditional countryside mosaic, have over the past half century been abandoned. These abandoned groves are vigorous and are now expanding, causing various problems, including loss of diversity and damage to cropland. To control and manage these groves, an effective yet efficient system for documenting and monitoring th...
Møller and co-workers (Møller et al. 2007) observe an ‘elevated frequency of abnormalities in barn swallows (Hirundo rustica) at Chernobyl’ and ‘can think of no alternative explanations other than exposure to radiation that can have caused the observed patterns’. However, an obvious alternative hypothesis (e.g. Pikulik & Plenin 1994) is that apparent impacts on birds may be due to ecosystem cha...
Land use impacts are commonly quantified and compared using 2D maps, limiting the scale of their reported impacts to surface area estimates. Yet, nearly all land use involves disturbances below the land surface. Incorporating this third dimension into our estimates of land use impact is especially important when examining the impacts of mining. Mountaintop mining is the most common form of coal...
Climatologists generally expect an anthropogenic global warming that could raise sea level 50-150 centimeters in the next century and more thereafter. One of the impacts would be the loss of coastal wetlands. Although the inundation of adjacent dry land would enable new wetlands to form, much of this land is or will soon be developed. If developed areas are protected, wetlands will be squeezed ...
In 2010, concerns regarding Japan’s excessive dependence on imports for food and energy caused the Japanese government to introduce subsidies to stimulate biofuel crop production. In this paper, we study the viability of price subsidies and certain other policies with respect to increasing the production of biofuel crops. First, we estimate the elasticity of the supply of Japanese agriculture w...
Institutional settings play a key role in shaping land cover and land use. Our goal was to understand the effects of institutional changes on agricultural land abandonment in different countries of Eastern Europe and the former Soviet Union after the collapse of socialism. We studied ∼273 800 km2 (eight Landsat footprints) within one agro-ecological zone stretching across Poland, Belarus, Latvi...

Abandoned mine lands (AMLs) associated with past coal-mining scar Pennsylvania’s landscape with environmental and safety hazards. Reclamation projects eliminate and reduce hazards AMLs pose. Due to the large number of AMLs and limited funds, precedence is given to reclaim the most hazardous sites first. These sites are identified through an assessment process that assigns priorities to AMLs. Ho...
The impact of water use in areas with abundant freshwater resources should not be the same as areas with limited resources. This impact is quantified as water scarcity footprint. The monthly water stress index with reference to environmental water requirement is proposed as a characterization factor. The biofuel policies of Thailand—cassava and sugarcane for bioethanol, and oil palm for biodies...
