Science, technology and innovation

*Dr. Quach Duc Tin - Deputy Director of the Institute of Geological Sciences and Mineral Resources chaired the Workshop*

Speaking at the opening of the Workshop, Dr. Quach Duc Tin said: In the jubilant atmosphere of organizing events to celebrate Vietnam Science and Technology Day 2023 across the country, the Institute of Geosciences and Mineral Resources organized the Workshop "Science, technology and innovation - Enhancing national potential and position".

The workshop attracted the participation of experts, managers, scientists from many agencies inside and outside the Ministry of Natural Resources and Environment . This is an opportunity for scientists, managers, educators, trainers and businesses to meet, exchange and summarize research results and the ability to apply in production practice. At the same time, propose new research directions in line with the socio-economic development trend of the country.

Reporting on the scientific and technological activities of the Institute of Geosciences and Mineral Resources in the period of 2015-2022, Dr. Nguyen Dai Trung, Head of the Department of Science, Training and International Cooperation of the Institute, said: In the period from 2015 to 2022, the Institute has presided over the implementation of 47 scientific and technological tasks at all levels, including 3 national-level tasks, 27 ministerial-level tasks, and 17 grassroots-level tasks.

The process of implementing the tasks has achieved many outstanding results that have been applied in research, management and practice, contributing to the general development of science and technology activities, contributing to the cause of industrialization and modernization of the country in the conditions of a socialist-oriented market economy and international integration.

The Institute has transferred the results to the Dong Van Karst Plateau Global Geopark Management Board on the scientific and legal basis for the establishment, conservation, and rational use of geological heritage and geoparks in Vietnam for reference, serving the construction and development of conservation and rational use, and planning of the Global Geopark.

At the same time, the Institute provides scientific and technological services to the localities: Ha Giang, Cao Bang, Ninh Binh, Quang Ninh, Dak Nong, Dak Lak, Gia Lai, Quang Ngai, Thanh Hoa, Phu Tho, Thai Nguyen, Quang Ninh, Bac Kan,... serving the construction and development, conservation and rational use, planning of Geoparks - Geoheritage, geological investigation; determining the causes and proposing measures to handle the phenomenon of landslides,...

The Institute also transfers a lot of knowledge and techniques to raise public awareness about the rational use of water resources in limestone mountains, more importantly, it implements training and transfers the use of research results of the task in a systematic way; helps technicians and managers grasp the operation, maintenance, and repair processes as well as sustainable development; deploys the construction of 3 water distribution systems for Dong Van Town and neighboring areas of Thai Phin Tung commune with the volume including: 1 water tank of 2000m3, 1 centralized water distribution tank of 200m3, 6 village-level distribution tanks and dozens of other centralized water tanks and supplies; builds a water distribution pipeline system for a large area with a population of nearly 10,000 people.

Dr. Do Minh Hien from the Department of Economic Geology and Geoinformatics, Institute of Geosciences and Mineral Resources presented a paper at the Workshop.

Regarding the Institute's orientation for science and technology development until 2030, Dr. Nguyen Dai Trung said that the Institute will research and apply modern methods and advanced technologies to effectively serve basic geological and mineral investigation activities; research scientific foundations, orient investigation work, apply monitoring technology, observe geodynamic processes in some key areas, greatly affected by climate change and rising sea levels (subsidence in the Mekong Delta, uplifting and lowering of geological structures in the Southern region, erosion of river banks, coastlines, etc.), and measures to limit and mitigate.

The Institute also develops applications of automation, digitalization, modeling, monitoring, observation, forecasting, and early warning technologies for geological disasters (landslides, mudflows, flash floods, etc.), environmental incidents, etc.

At the workshop, Dr. Nguyen Quoc Khanh, Director of the Center for Remote Sensing and Geological Hazards, Institute of Geosciences and Mineral Resources, reviewed the research results and delimited areas sensitive to landslides in Thua Thien Hue. Accordingly, Thua Thien Hue province is assessed as a locality with an average risk of landslides compared to other provinces in the Central region. The results of delimiting areas sensitive to landslides include districts with high risks of landslides, including A Luoi, Nam Dong, Phong Dien, and Phu Loc.

The list of communes/wards proposed for detailed research and investigation at a scale of 1:10,000 includes: A Luoi district (including the areas of communes: A Dot, A Roang, Phu Vinh, Hong Ha and A Luoi), Nam Dong district with the area of Huong Son commune, Phong Dien district with the area of Phong Xuan commune. According to Dr. Nguyen Quoc Khanh, the results of delineating sensitive areas for landslides and proposing detailed investigations at a scale of 1:10,000 are used as a basis for orienting the investigation, assessment, forecasting and early warning of landslides to serve more effectively the planning of socio-economic development, planning of population rearrangement, and at the same time contributing to preventing, combating and minimizing damage caused by landslides and landslides in the locality.

In addition, these results will contribute to helping the city have a territorial planning orientation, build a socio-economic development plan in the future; directly serve the planning and infrastructure construction of the Thua Thien Hue area in the context of adapting to climate change and types of natural disasters such as landslides and rock slides.

Summarizing the results of the study on establishing landslide and mudflow hazard susceptibility maps at large scales using statistical methods, machine learning combined with the FlowR model, Dr. Do Minh Hien from the Department of Economic Geology and Geoinformatics, Institute of Geosciences and Mineral Resources said: The results of the study show that statistical and machine learning methods can be completely applied to establish landslide susceptibility maps at large scales of 1:10,000 for areas with limited input data. The model combines these methods with the FlowR model (an empirical model for assessing the propagation of gravity-related hazards) to establish landslide and mudflow hazard susceptibility maps suitable for application at scales of 1:10,000.

The results of the study will contribute to the reduction of landslide and debris flow hazards, supporting the territorial planning in the study area. The methods applied in this study can be applied to other areas to establish landslide and debris flow hazard sensitivity maps at similar scales.

Also at the Workshop, delegates discussed the results of research on mineral geology, mineralization origin, hidden minerals, geological disasters, landslides, water resources, etc., in which many new technologies and techniques were introduced to serve projects of investigation and assessment of minerals, geological disasters, water resources, zoning and warning of landslides, flash floods, etc. All these studies have contributed to enhancing the national potential and position in science, technology and innovation.
