明显的湿润季节性决定了该地区的气候，从而决定了秘鲁卡列洪德瓦伊拉斯（科迪勒拉布兰卡）雨养农业的特征。瓦拉斯市上方东坡昆卡奥基地区的农民将最近农业生产遇到的挑战主要归因于降水模式的变化。对附近 Recuay（1964 年至 2013 年）和 Huaraz（1996 年至 2013 年）站每日降水记录的统计分析并未证实所感知的变化。现有降水记录的时间分辨率不足或影响传统耕作方法的其他环境和社会政治因素可能是本研究调查的两个信息来源之间缺乏一致性的原因。
Pronounced hygric seasonality determines the regional climate and, thus, the characteristics of rainfed agriculture in the Peruvian Callejon de Huaylas (Cordillera Blanca). Peasants in the Cuenca Auqui on the eastern slopes above the city of Huaraz attribute recently experienced challenges in agricultural production mainly to perceived changes in precipitation patterns. Statistical analyses of daily precipitation records at nearby Recuay (1964 to 2013) and Huaraz (1996 to 2013) stations do not corroborate the perceived changes. Either insufficient temporal resolution of available precipitation records or other environmental and sociopolitical factors impacting traditional farming methods may be the reason for the lack of concordance between the two information sources investigated in this study.
