Th e sweet granadilla (Passifl ora ligularis Juss) (Passifl oraceae), native to Tropical America, can be found wild in Peru.However, given the vulnerability of agricultural systems, climate variations, and its relevance to the economy and foodsecurity, it is important to evaluate the impact of climate variability and agricultural systems on the cultivation ofsweet granadilla P. ligularis from Oxapampa, Pasco, Peru. For this purpose, information was collected on the climaticvariables from the National Service of Meteorology and Hydrology (SENAMHI) of Peru as well as variables relatedto crops, such as cultivated area and the yield of sweet granadilla cultivation in diff erent productive plots. Th e annualfi gures obtained from the Statistical Compendium of the Regional Statistical System-INEI of the Department of Pascowere used. Information was obtained through surveys of farmers of the Oxapampa locality and from professionals ofinstitutions related to the cultivation of granadilla: Regional Directorate of Agriculture and the National UniversityDaniel Alcides Carrión (UNDAC) of Peru. Climatic factors had a positive impact on the yield of granadilla fruits, andit was the highly adaptable Colombian ecotype (“Colombian”) that improved the yield of the crop per hectare, whichvaried from 5 tn / ha / year to a range of 10 to 15 tn / ha / year. However, these factors had a negative impact on localecotypes which, despite being the source of genetic resistance to pests and diseases, were displaced by the introducedecotype. Given the superior profi tability of the cultivation of sweet granadilla on livestock, changes were generated inthe use of land, strong indiscriminate felling of native forests, decrease in pasture area, milk production, and in productsderived from primary sources.
