该研究发现棉花种植环节的环境影响取决于灌溉、农药和化肥用量。全球约有一半的棉田使用地下水灌溉,农药平均施用量为 1.57 kg/ha,氮磷肥平均投入量为150 kg/ha。全球各棉区灌溉、农药、氮肥施用量差异较大,经济发展水平高的地区施用量较高,而经济水平和水资源有限的棉区施用量较少,亟需因地制宜提高灌溉用水、化肥、农药利用效率,减少生产环节的环境影响。研究还发现,除了棉花种植环节对环境的影响外,...
Sustainable development is that which meets the needs of the present without foreclosing the needs or options of the future. Many studies have been published on how to assess sustainability using indi...
The increase of tourism in coastal protected areas is potentially one of the drivers of ecosystem fragmentation with the consequent important damages to their biodiversity values. One of the key manag...
The population of beluga whales in Cook Inlet, Alaska, is in decline, and since 2000 these whales have been under consideration for designation as "endangered" under the Endangered Species Act (and we...
Electricity deregulation has aroused concern that environmental quality might be harmed by consumer preferences for cheap, “dirty” (e.g., coal) electricity products, despite the perhaps stronger influ...
This study explores and seeks to explain the EIA procedures practice gap in Lao PDR. It reviews the literature and studies EIA legislation, administrative procedures, guidelines, and relevant document...
The environmental impacts are commonly quantified in the EIA studies by rating, ranking and scaling. The National EIA Guidelines, 1993, Nepal provides a guideline to score the impacts in terms of magn...
Industries have contributed for human development by improving human life styles, increasing human life expectancy rate, providing more and more jobs. Still industrialization has many negative impacts...
Since Turkey’s economy and population is rapidly growing, Turkey mostly meets its energy demand from imported fossil sources due to the very limited indigenous oil and natural gas resources. However, ...
There are an estimated 400 000-550 000 km of unpaved resource roads in British Columbia. These roads are used for forest, mineral, and energy development, commercial and public recreation, and in some...
The distribution of metals (aluminum, manganese, iron, copper, zinc, cadmium and lead) between suspended particles and solution phase has been studied by analysis of time series data in a stream rec...
Variations in metal concentrations in a heavily polluted stream receiving acidic leachates from an old mine tailings deposit are analysed from a hydrological perspective. From an extensive data mate...
A diversity of hydrological and hydrochemical data is the foundation for an integrated modelling study of a leaching tailing deposit at Bersbo in southern Sweden. A distributed conceptual water bala...
The release and distribution of metals as well as acid from a mine tailings deposit into a stream have been studied, particularly the distribution and neutralization of acids, the distribution and c...
