Impact of climate change on crop yield of corn (Zea mays L.) in the Canton Junín, Province of Manabí

Agriculture provides a significant fraction of the food consumed worldwide. In Ecuador, large area is dedicated to production corn (Zea mays L.). However, progress current projections in agriculture may be directly affected by climate change and its effects. The present study aims evaluate impact on maize L.) crop yields over last 10 years (2010 - 2020) predict future under different scenarios proposed Intergovernmental Panel Climate Change (IPCC). Variables such as rainfall, temperatures, heliophany, evapotranspiration, solar radiation, humidity recorded monthly annual basis were considered. data obtained from two weather stations, their yield this farms was analyzed linear regression. ArcGis program used 10-year (yield) IPCC scenarios, through analysis Maxent model for Zea mays. situation Junín canton considerable climatic variations other serious effects that are detrimental local agricultural system.
