Abstract

This study analysed factors influencing the decision to use chemical fertilisers by farmers at the household level, and it included a related assessment of nutrients in nearby water bodies. One focus group discussion was held at each site, and then a total of 198 and 58 households in Lake Phewa and Kulekhani Reservoir, respectively, were surveyed. The results reveal that 90% and 55% of households applied chemical fertilisers in Lake Phewa and Kulekhani Reservoir, respectively. A logistic regression model indicated that the two factors having a significant positive influence on the decision to use chemical fertilisers were higher vegetable yield and the amount of urea available to farmers Water sampling indicated that phosphorous concentrations were relatively high in both these water bodies compared to previous studies in other nearby lakes.

农民施用化肥对Phewa湖和Kulekhani水库的影响

这项研究分析了影响农民在家庭层面使用化肥的因素，并对附近水体中的营养物质进行了相关评估。在每个地点举行了一次焦点小组讨论，然后分别对Phewa湖和Kulekhani水库的198户和58户家庭进行了调查。结果显示，Phewa湖和Kulekhani水库分别有90%和55%的家庭使用化肥。逻辑回归模型表明，对使用化肥的决定有显著积极影响的两个因素是较高的蔬菜产量和农民可获得的尿素量。水采样表明，与之前在附近其他湖泊进行的研究相比，这两个水体中的磷浓度相对较高。

期刊介绍： Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
