Abstract

In order to meet the health and safety needs of our attendees and staff, the 2021 International Conference on Agriculture Science and Water Resource (ASWR2021) which was scheduled to be held in Guangzhou, China, was held virtually online during January 22nd-25th, 2021. Being different from the traditional gatherings we all know, this virtual conference allows us to connect in new ways while keeping expenditure saving and maintaining social distancing. Presentations of presenter from different countries are accessible to hundreds of researchers effectively.Closely related to life, agricultural science and water resource have always been hot research topics and are gaining more and more attention from various countries. Agricultural production depends to a large extent on limited resources such as soil, water, nutrients and energy. At the same time, the misconduct usage of water resources brings about the increasingly prominent environmental problems. Under such condition, ASWR2021 would lay a platform for the interaction between experts and scholars and engineering technicians in the related fields to jointly promote the challenge aspects and discuss future developmentsand discuss future developmentsand discuss future developmentsand discuss future developmentsand discuss future developmentsand discuss future developmentsand discuss future developmentsand discuss future developmentsand discuss future developmentsand discuss future developmentsand discuss future developmentsand discuss future developmentsand discuss future developmentsand discuss future developmentsand discuss future developmentsand discuss future developments in this field.More than 60 individuals attended this online conference via cloud platform for video and audio Zoom. The conference was divided into two parts: keynote speeches and oral presentations. In the keynote speeches part, three keynote speeches with allocated time about 45 minutes each were delivered by Prof. Jiří Jaromír Klemeš, Brno University of Technology, Czech Republic; Prof. Defu Zhang, Xiamen University, China and Assoc. Prof. Wenchao Li, Hebei Agricultural University, China. Their insightful speeches gave our participants great inspiration. In the oral presentations part, experts and practitioners interested in Agriculture Science and Water Resource were given about 10 minutes to present their oral presentations to discuss state-of-the-art research results, perspectives of future developments, and innovative applications of their research.The conference ASWR2021 focuses on the discussion of the various aspects of agriculture, water resource, animal science, plant science and soil science. Some submitted manuscripts within the scope of the conference, which representing the advanced studies, were selected as the excellent papers and complied in the Conference Proceedings. Every accepted paper has undergone peer review process arranged by the Editorial Committee. At least two independent reviewers should review and approve a paper. If reviewers had different opinion on it, more reviewers would be selected to help make a final decision. We believe that the Proceedings will serve as an important research source to provide recent development and information related to agriculture, water resources and environment protection.On behalf of the Organizing Committee, we would like to take this opportunity to express our sincere gratitude to all authors and presenters. We are also grateful to the Technical Program Committee members and reviewers as well as all the colleagues from IOP publisher. It is the joint efforts of everyone that makes the conference a great success.Committee of ASWR2021List of Committee Members are available in this Pdf.
