Case Study on the Effect of Climate Change on Irrigation

Abstract

Irrigation plays a crucial role in boosting agricultural output and productivity for the long-term viability of the nation's economy. Due to the rapid change in the climate system, there will be obvious effects on current activities for the design and management of irrigation systems. The future of this paper will focus on assessing how climate change affects the crop yield and irrigation requirements of the Wonji Shoa Sugarcane Plantation Estate. It used projections from the Cordex regional climate model (RCM) with bias correction for the medium concentration representative path way 4.5RCP scenario and the high concentration representative path way 8.5RCP scenario for future climate data. The AQUACROP model was then fed data that had been downscaled. For both the 4.5rcp and 8.5rcp scenarios, the time series show a significant increase in maximum and minimum temperature values and a slight increase in precipitation.
