Abstract

Climatic and environmental changes are important issues for present day research. In this paper, the effect of climatic and environmental changes on water requirements of Sweet Pepper crop grown in Qassim-Saudi Arabia have been investigated by incorporating the impacts of climatic and environmental changes on precipitation and temperature in the Qassim region. The base period for data is taken as 1999 -2024. The changes in precipitation and temperature have been predicted by Global Circulation Model (GCM) under RCP 2.6 (Representative Concentration Pathway 2.6) for a period of 25 years. Evapotranspiration has been estimated using Penman-Monteith equation. Its best parameters have been estimated by the General Reduced Gradient (GRG) technique. The water requirements of Sweet Pepper crop grown in Qassim have been estimated using CROPWAT model. Finally, the impact of temperature and precipitation variations on crop water requirements have been estimated. It is observed that the water requirements of Sweet Pepper will slightly increase in the future in the Qassim region. The results of this research will be useful for sustainable water planning, development and management.
