Abstract In the context of modern agriculture, irrigation is a widespread technique employed to help crop growth and ensure food production. However, there are various irrigation strategies, each with its distinct set of components and machinery. These differences in irrigation methodologies impact the environment in different ways. In this work, we focus on greenhouse gases emissions throughout the agricultural process. Our primary research objective is to comprehensively evaluate the environmental impact, in terms of kg of CO2 equivalent, of several irrigation strategies both in scenarios with and without the use of fertilizers, with the aim of identifying the most environmentally sustainable option.
