摘要

The study was conducted in the districts of Nakaseke and Nakasongola stratified into four farming systems of crop dominancy, pastoralists, mixed crop and livestock and fishing. The study was guided by two research questions: (1) how do community residents perceive climate change/variability? (2) What is the trend and nature of climate variability and how does it compare with people’s perceptions? Ninety eight percent (98%) of the respondents reported that the routine patterns of weather and climate had changed in the last 5 to 10 years and it has become less predictable with sunshine hours being extended and rainfall amounts being reduced. This compared well with the analyzed secondary data. Over 78% respondents perceived climate change and variability to be caused by tree cutting other than the known scientific reasons like increase in industrial fumes or increased fossil fuel use. Climate data showed that over the period 1961 to 2010 the number of dry spells within a rainfall season had increased with the most significant increase observed in the first rainfall season of March to May as compared to the season of September to November. The first dry season of June/July to August is short while the second dry season of December to February is long during the study period. The two rainfall seasons of March to May and September to November seem to be merging into one major season from May to November. Temperature data shows a significant increasing trend in mean annual temperatures with the most increase observed in the mean annual minimum temperatures than the maximum temperatures.

(2)气候多变性的趋势和性质是什么,与人们的看法相比如何? 98%(98%)的受访者表示,在过去5至10年中,天气和气候的常规模式发生了变化,随着日照时间的延长和降雨量的减少,这种变化的可预测性越来越差。这与分析的辅助数据进行了很好的比较。超过78%的受访者认为气候变化和变异性是由砍伐树木引起的,而不是已知的科学原因,例如工业烟气的增加或化石燃料的使用增加。气候数据显示,在1961年至2010年期间,降雨季节内的干旱季节数量有所增加,与9月至11月的季节相比,在3月至5月的第一个降雨季节中观测到的旱灾最为明显。在研究期间,六月/七月至八月的第一个旱季很短,而十二月至二月的第二个旱季很长。 3月至5月和9月至11月这两个降雨季节似乎正在合并为5月至11月的一个主要季节。温度数据显示年平均温度有明显的上升趋势,其中年平均最低温度比最高温度增加最多。
