Comparing peasants' perceptions of precipitation change with precipitation records in the tropical Callejón de Huaylas, Peru


Gurgiser, Wolfgang; Juen, Irmgard; Singer, Katrin; Neuburger, Martina; Schauwecker, Simone; Hofer, Marlis; Kaser, Georg (2016). Comparing peasants' perceptions of precipitation change with precipitation records in the tropical Callejón de Huaylas, Peru. Earth System Dynamics, 7(2):499-515.

Abstract

Pronounced hygric seasonality determines the regional climate and, thus, the characteristics of rained agriculture in the Peruvian Callejón 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.
