Special Issue Information
Dear Colleagues,
Irrigation is critical for agricultural production. Presently, 23% of global cropland areas are irrigated and provide approximately 40% of total food production. Meanwhile, it also uses approximately 70% of freshwater. At the 3rd World Irrigation Forum, India, 2019, it was predicted that by 2030 and 2050, the increasing global population will need at least 40% and 55% more water, respectively. Moreover, climate change increases the uncertainty concerning available water resources. Therefore, water should be used much efficiently by producing more food with each drop of water to support the increasing population and reduce the water shortage risk.
Using advanced technologies, including new irrigation products, crop, soil water and evapotranspiration monitoring systems, remote sensing methods, mathematical models, optimized irrigation scheduling, new agricultural facilities, and related issues, could greatly save water resources and then enhance the water productivities.
In this Special Issue, we want to explore recent advances in water-saving technologies and theories, based on laboratory experiments, field investigations, and physical models. Moreover, papers on non-traditional irrigation water resources, agronomy practices, and the effects of climate change on agricultural water use and agricultural water management policies are welcome.
