Abstract

La papa es uno de los cultivos más importantes para la seguridad alimentaria en Bolivia, y gran parte de los sistemas agrícolas del altiplano boliviano se basan en este cultivo. Sin embargo, los rendimientos nacionales son los más bajos de la región (5.7Tnha-1) y los sistemas agrícolas son altamente vulnerables a los impactos del cambio climático. Esta situación puede agravarse en escenarios climáticos futuros. El objetivo del presente estudio es evaluar la adaptación al cambio climático del cultivo de la papa bajo el peor escenario climático para el año 2050 utilizando tres medidas de adaptación: gestión del calendario agrícola, manejo de la diversidad biológica y aplicación de riego complementario. Para ello, se emplea el modelo de simulación de cultivos APEX y se simula el crecimiento y rendimiento de papa bajo el escenario Trayectoria de Concentración Representativa (RCP) 8.5 en la localidad de Patacamaya. Los resultados muestran un incremento significativo en los rendimientos productivos para todas las medidas, y cuando se combinan las tres medidas, la efectividad para reducir los impactos del cambio climático se incrementa, y en consecuencia los rendimientos productivos aumentan en un 48% (46Tnha-1) y la resiliencia de los sistemas agrícolas basados en papa mejora.
