Abstract

This study was conducted in the period of January 2014 to December 2015. The main objective of the study was to investigate the impact of climate change in the water basin and its catchment areas. The method was a survey of relevant literatures. Climate change is a big issue not only in developed countries but also in developing countries. The study found that the temperature is rising with 2.00 C on average per annum in western Nepal. This is relatively 3 times higher than lower temperature increase within the country and significantly higher in comparison to global trend of temperature variation. Over the last 36 years (1975-2010) in western Nepal, temperature is rising on an average of 1.2°C per annum. This is twice as compared to the global increment. This indicates more vulnerability of climate change in hills and high hills of Nepal. The average rise of temperature in Nepal is 0.06oC per year. The climate-induced disasters are; drought, severe floods, landslide, etc. They also have negative effects in agriculture in the hills and high hills of Nepal.HYDRO Nepal JournalJournal of Water, Energy and Environment Issue: 23Year: 2018

尼泊尔西部山地流域气候变化及其影响研究进展

本研究时间为2014年1月至2015年12月。研究的主要目的是调查气候变化对流域及其集水区的影响。方法是查阅相关文献。气候变化不仅是发达国家的大问题，也是发展中国家的大问题。研究发现，尼泊尔西部的气温正以平均每年2摄氏度的速度上升。这比国内较低的温度上升幅度高出3倍，与全球温度变化趋势相比也明显更高。在过去的36年里(1975-2010年)，尼泊尔西部的气温平均每年上升1.2°C。这是全局增量的两倍。这表明尼泊尔的丘陵和高山更容易受到气候变化的影响。尼泊尔的平均气温每年上升0.06摄氏度。气候引起的灾害是;干旱、严重洪涝、滑坡等。它们也对尼泊尔山区和高山的农业产生了负面影响。HYDRO Nepal journal of Water, Energy and Environment Issue: 23Year: 2018
