摘要:The threat of climate change is affecting and will affect the important natural resources including water. Considering this, a study was carried out to assess the impact of climate change on crop water requirement. In this study, potato was taken as the refernce crop for its growing period and its high response to irragation. The ET values from the potato field were measured using field water balance method and the data was used to validate the CROPWAT model. After proper validation of CROPWAT model, the model was used to determine the irrigation requirement of potato using current and future (prediction years: 2020 and 2050) weather data. It was observed that irrigation water requirement will be increased by 7 to 8% during 2020, while it may increase about 14 to 15% during 2050.
