Abstract

The main objective of this paper is to capture climate change impact on endogenous crop choices by Peruvian farmer’s and the impacts on their expected income. The model is estimated across 110 227 farmers in Peru. The results show that both temperature and precipitation affect the selection crops. The study estimates that climate change would reduce the expected revenue per hectare in the range of 8% and 13% depending on the climate scenario. Climate change induces a reduction of conditional income for alfalfa, rice, coffee and maize (durum) and increases for potato, starchy maize, bananas and grapes for both climate models, with results mixed for cassava depending on the climate model. Rice and coffee are the crops with the greatest losses, while the native potato is the crop with the highest gain. Also, the probability of choice of maize and banana increases as temperature and precipitation increases.// El principal objetivo de este artículo es captar la influencia del cambio climático en la selección endógena de cultivos de los agricultores y los impactos sobre su ingreso esperado. El modelo se aplica a 110 227 productores en Perú. Los resultados muestran que la elección de cultivos se ve afectada por el clima. Se estima una caída de entre 8 y 13% de los ingresos esperados por hectárea. El cambio climático provocará una reducción de los ingresos condicionales para la alfalfa, el arroz, el café y el maíz amarillo duro y aumentos para la papa, el maíz amiláceo, el plátano y la uva; se presentan resultados mixtos para la yuca, dependiendo del modelo climático. El arroz y el café muestran las mayores pérdidas, mientras que la papa nativa obtiene la mayor ganancia. Se muestra que la probabilidad de elegir la cosecha de maíz y de plátano aumenta con los incrementos de temperatura y precipitación
