Abstract

Monsoon patterns have been changing noticeably in recent years around the globe. These changes have tremendous effects on agriculture systems especially in the areas where rainfall is the precondition of agriculture. This paper will investigate monsoon patterns in Nepal and how they correlate with recorded rice yields. The results were analyzed and cross-checked with AquaCrop, a crop water productivity model. The findings indicate that the Nepal’s monsoon patterns do not follow a definitive trend. Parameters such as onset and withdrawal dates, duration and distribution are quite unpredictable. The patterns, however, do have direct impact on national average rice yields, but that effect has turned less sensitive in recent years. The findings suggest that though monsoon has vital role on rice production in Nepal, where agriculture systems depend primarily on rainfall, more research is required to predict more accurately and precisely the production functions and relationships to yield. The better we understand this relationship, the more we can compensate for adverse monsoon patterns through anticipatory deployment of ag-technologies and advanced management options. Furthermore, support from legislators will be required to move these ideas into practice.

气候变化及其对水稻产量的影响
近年来,全球季风模式发生了显著变化。这些变化对农业系统产生了巨大的影响,特别是在以降雨为农业先决条件的地区。这篇论文将调查尼泊尔的季风模式以及它们如何与记录的水稻产量相关联。结果与AquaCrop(作物水分生产力模型)进行了分析和交叉核对。研究结果表明,尼泊尔的季风模式并不遵循一个明确的趋势。诸如发病和停药日期、持续时间和分布等参数是不可预测的。然而,这种模式确实对全国平均水稻产量有直接影响,但这种影响近年来变得不那么敏感了。这些发现表明,尽管季风对尼泊尔的水稻生产起着至关重要的作用,但需要更多的研究来更准确和精确地预测生产功能及其与产量的关系。尼泊尔的农业系统主要依赖于降雨。我们越了解这种关系,就越能通过预期部署农业技术和先进的管理方案来弥补不利的季风模式。此外,要将这些想法付诸实践,还需要立法者的支持。DOI: http://dx.doi.org/10.3126/hn.v16i0.12215 HYDRO尼泊尔水能与环境杂志2015年1月16日第23-27页上传日期:2015年3月1日
