Abstract

Quinoa is a strategic crop for the food security and rural economy of Puno, but its production is highly vulnerable to rising temperatures, precipitation variability and limited water availability. Based on the calibration and validation of the local AquaCrop model for the Blanca de Juli, Pasankalla and Salcedo INIA varieties, yield changes were projected for Taraco and Juliaca under the RCP 4.5 and RCP 8.5 scenarios. The results project greater yield reductions under rainfed conditions and under higher-emission scenarios, while Blanca de Juli displays better relative performance. These results support the need for policies focused on technified irrigation, agro-climatic risk management, and monitoring systems to strengthen quinoa adaptation on the Peruvian high plains known as the altiplano.
