PrefaceSince the Doi Moi policy launched in 1986, Vietnam opened up the country’s economic liberalization over the past 3 decades. While achieving remarkable economic growth, Vietnam has faced considerable challenges in environmental and resources management. The rapid growth of urbanization and industrialization has placed an increase in pressures on the environments and available resources, through excessive exploitation and use. Further, the utilization, management and use of environment and natural resources have increasingly drawn much attention from both researchers and managers under the effects of global climate change impacts. The application of advance technologies and management practices have become a vital of concern in the age of the 4th industrial revolution with an emerging of advance technologies.We would like to welcome you to the International Conference on Environment, Resources and Earth Sciences (ICERES 2020) in associated with the National GIS Conference 2020 (GIS for Smart Cities towards Sustainable Development) which the will be held during 1 – 5 December 2020 at Ho Chi Minh City University of Technology (HCMUT), Vietnam National University Ho Chi Minh City. ICERES 2020 is co-organized by HCMUT, Nong Lam University (NLU) and Esri Vietnam in which. The Conference is financially supported by Ho Chi Minh City University of Technology, Vietnam National University Ho Chi Minh City, Nong Lam University and Esri Vietnam.The main objective of the conference is to provide a platform for researchers, academicians, engineers, businessmen, managers, and postgraduate students in the field of environmental and resources management, geospatial technologies, and earth sciences to present their recent studies and latest research results. In addition, this conference aims to provide a setting environment for scientists and managers to exchange new ideas, innovative thinking, and to explore applicable experiences via face-to-face discussions, as well as establishing collaborative research projects or business relations, and to enable partners for their future collaborations.The conference program was organized into ten (10) sessions covering topics of environment and natural resources management, geospatial technologies, and earth sciences, imcluding: Smart Cities, Digital Twin Cities (Cyber Cities), Smart Building; (ii) Application of GIS in State Management; (iii) Disaster Reduction and Risk Management; (iv) Environment, Natural Resources Management and Sustainable Development; (v) 3D GIS, Laser Scanning, and Ground Penetrating Radar (GPR); (vi) Digital Imagery Processing (Satellite, UAV, Air plane); (vii) IoTs, AI, and Big Data for WebGIS; (viii) Integration of Lidar and GIS; (ix) Building Information Model (BIM) Technology; and (x) Global Navigation Satellite System (GNSS). Overall, the conference has attracted more than 138 papers, and among them, 46 high-quality papers were recommended to submit for the IOP Conference Series: Earth and Environmental Science proceedings book for peer-reviewing. Then, the double-blind review process was carried out for the 46 papers, in which each paper has been reviewed for its merit and novelty by at least two reviewers and one editor by matching the content areas. As a result, a total of 25 papers have been finally selected for this proceedings book. We believe that this proceedings book provides a broad overview of recent advance studies in the fields of environment, natural resources, disaster reduction and risk management, sustainable development, geospatial technologies (GIS and remote sensing) and earth resources for readers.Finally, we would like to express our sincere thanks to (i) Department of Science and Technology – Vietnam National University Ho Chi Minh City; (ii) the Rector of HCMUT (Assoc. Prof. Mai Thanh Phong); (iii) the Rector of Nong Lam University (Prof. ) for their help and assistance in administrative works and other supports. Special thanks go to Kayleigh Parsons for always responding promptly. We would like to thank all the reviewers for their timely and rigorous reviews of the papers and thank all the authors for their submissions.Ho Chi Minh City, November 2020Armando A.
