The Indonesian land area is 191.1 million ha, part of which abandoned in various agroecosystems that have the potential for expanding agricultural area. purpose this research was to geospatially analyze based on its agroecosystem at national and district levels, as well evaluate suitability development. methods included: (1) geospatial analysis cover map a scale 1:250,000 combined with soil cli...

The collapse of collective farming in Russia after 1990 and the subsequent economic crisis led to the abandonment of more than 45 million ha of arable lands (23% of the agricultural area). This was the most widespread and abrupt land use change in the 20th century in the northern hemisphere. The withdrawal of land area from cultivation led to several benefits including carbon (C) sequestration....

The geochemistry of rare earth element (REE) variations in acid waters is being studied as part of the U. S. Geological Survey Abandoned Mine Lands Initiative in two pilot watersheds, upper Animas, Colorado and Boulder, Montana. The following objectives are under investigation: (1) comparison of acid mine waters and naturally acidic springs, (2) determination of whether the dominant control on ...

Increased production of biomass for energy has the potential to offset substantial use of fossil fuels, but it also has the potential to threaten conservation areas, pollute water resources and decrease food security. The net effect of biomass energy agriculture on climate could be either cooling or warming, depending on the crop, the technology for converting biomass into useable energy, and t...

Background:Poisoning with ethylene glycol (EG) can be fatal even if appropriate treatments are delivered. EG poisoning usually causes central nervous system depression, cardiovascular dysfunction, metabolic acidosis and acute renal failure (ARF). Case Report:A 33-year-old man was referred to the emergency department with reduced consciousness and dyspnea of four-hour duration due to unknown rea...

Conversion of slope cropland to perennial vegetation has a significant impact on soil organic carbon (SOC) stock in A horizon. However, the impact on SOC and its fraction stratification is still poorly understood in deep soil in Loess Hilly Region (LHR) of China. Samples were collected from three typical conversion lands, Robinia psendoacacia (RP), Caragana Korshinskii Kom (CK), and abandoned l...

When large carnivores occupy peripheral human lands conflict with humans becomes inevitable, and the reduction of human-carnivore interactions must be the first consideration for those concerned with conflict mitigation. Studies designed to identify areas of high human-bear interaction are crucial for prioritizing management actions. Due to a surge in conflicts, against a background of social i...

federal lands to facilitate resource extraction, recreation, and transportation (Havlick 2002) – enough to drive to the moon and back. While these roads provide important services, their construction and presence can also influence the hydrology, geomorphology, and ecosystem processes. They can substantially alter hillslope hydrology by reducing soil infiltration, concentrating water through ro...
