Intensive land expansion of commercial oil palm agricultural lands results in reducing the size of peat swamp forests, particularly in Southeast Asia. The effect of this land conversion on macrofungal biodiversity is, however, understudied. We quantified macrofungal biodiversity by identifying mushroom sporocarps throughout four different habitats; logged peat swamp forest, large-scale oil palm...

Driven by global population and standard of living increases, humanity co-opts a growing share of the planet’s natural resources resulting in many well-known environmental trade-offs. In this study, we explored the impact of agriculture on a resource fundamental to life on Earth: terrestrial vegetation growth (net primary production; NPP). We demonstrate that agricultural conversion has reduced...

A survey of all county planning departments in Washington State indicated that protecting agricultural land is a major concern at the county level. Maintenance of the agribusiness sector is the main reason for protecting agricultural land, while the preservation of open space and rural lifestyles was of secondary importance. As a result, most Washington counties have implemented a broad range o...

Concentrations of thermotolerant coliform bacteria, presumptive E. coll, and presumptive fecal streptococci were determined from ditches, brooks, and natural ponds in six agricultural areas and 22 uninhabited pristine areas in southern Finland in the summer of 1987. For comparison, the same fecal indicators were enumerated from the effluents of three wastewater t eatment plants. The objective w...

Carbon dioxide is an important greenhouse gas and a major agent of climate change. This study quantified carbon (C) emissions from energy consumption and C storage and uptake by greenspace for three cities in middle Korea: Chuncheon, Kangleung, and Seoul. Carbon emissions were estimated using C emission coefficients for fossil fuels consumed. Carbon storage and uptake by woody plants were compu...

Urban sprawl (US), propelled by rapid population growth leads to the shrinkage of productive agricultural lands and pristine forests in the suburban areas and, in turn, adversely affects the provision of ecosystem services. The quantification of US is thus crucial for effective urban planning and environmental management. Like many megacities in fast growing developing countries, Chennai, the c...

Pharmaceuticals and personal care products including all human and veterinary drugs, are emerging contaminants of concern [1,2]. Among these pharmaceuticals and personal care products are antibiotics [3]. About 50 to 90% of antibiotics and/or their metabolites are eliminated from the body through urine and feces which then enter the environment through sewage treatment plants or organic fertili...

INTRODUCTION In many countries around the world “developers” take the best agricultural lands for housing, and urbanization spreads rapidly. As a result, the agricultural industries are pushed into less productive lands in which the climate is not the most suitable for crops. A very good example is found in Israel. The best agricultural area is along the Mediterranean coast where the citrus ind...
