Guo Huadong： Earth Big Data promotes the sustainable development of the Belt and Road Initiative.

　　How does the "Digital Silk Road" help realize the goal of sustainable development? Guo Huadong, an academician of the China Academy of Sciences, said here on the 7th that the realization of sustainable development goals and specific indicators requires actions at the global, national and local levels, and big earth data can provide information, goals and assistance for these efforts and activities.
　　The second Digital China Construction Summit is being held in Fuzhou, and the A-class strategic pilot science and technology project "Earth Big Data Science Project" of China Academy of Sciences brought scientific research results to the summit.
　　Earth big data is the big data formed by the intersection and integration of earth science, information science and space science and technology. The data comes from but is not limited to space-based observation data, but also includes land, ocean, atmosphere and data related to human activities.
　　Guo Huadong, head of the project, chairman of the Digital Silk Road International Science Program and academician of the Chinese Academy of Sciences, was interviewed by a reporter from China News Service during the summit, and talked about how to conduct research based on the global big data project and the digital "Belt and Road" project to provide decision support and technical support for the United Nations Sustainable Development Goals (SDGs).
　　Guo Huadong pointed out that big data on earth is one of the key core technologies to realize the 2030 Agenda for Sustainable Development. It is the common demand of the countries along the Belt and Road to bring the global big data into the process of sustainable development and realize the coordinated development of society, culture, environment and ecology in the region and across countries through the advanced scientific and technological support of the global big data.
　　In 2016, China scientists initiated the Digital Silk Road International Science Program (DBAR) to realize the scientific service of global big data in the sustainable development goal of "Belt and Road" by sharing data, experience, technology and knowledge, and 53 countries, international organizations and international programs participated in it. At present, China Academy of Sciences has allocated more than 200 million yuan in the next five years to support the implementation of the DBAR plan.
　　"The DBAR plan will systematically monitor the status quo and evolution pattern of different ecosystems in the Belt and Road, including grasslands, forests, glaciers, cities, farmland and coastal zones." Guo Huadong said that the continuous accumulation, opening and sharing of global big data is an important resource and driving force to promote the development of digital "Belt and Road" scientific and technological innovation.
　　In January 2019, the DBAR earth big data system platform was officially launched. The system includes thematic data sets such as resources, environment, climate, disasters and heritage in the "Belt and Road" region, and 57 types of independent intellectual property data products. The shared data exceeds 120 trillion bytes, which can realize the browsing of basic geographic data throughout the "Belt and Road".
　　In January 2018, China Academy of Sciences launched the A-class strategic science and technology pilot project "Earth Big Data Science Project", aiming at building the world’s leading Earth Big Data platform and database, and promoting technological innovation, major scientific discoveries and one-stop all-round macro-decision support of Earth Big Data.
　　Guo Huadong said that in 2019, the core work of the Global Big Data Project will be the construction of "five balls, one satellite, one facility and 6SDG", and research will be carried out on several SDG targets, and efforts will be made to promote the monitoring and evaluation of six SDG indicators of the Global Big Data Service SDG2 Zero Hunger, SDG6 Water Resources, SDG11 Urbanization, SDG13 Climate Action, SDG14 Marine Ecology and SDG15 Terrestrial Ecology.
　　According to Guo Huadong, from 2018 to 2019, the earth big data technology was specially used to dynamically monitor the construction status of 127 overseas industrial parks in China from the establishment of the park to the end of 2018, and to monitor and evaluate the distribution pattern, development trends, construction status, resource endowment, risk status, ecological environment and socio-economic impact of overseas industrial parks in China.
　　At the same time, help those developing countries without technical and financial resources to monitor their urban development and study the relationship between land use rate and population growth rate; The evolution characteristics of giant panda habitat in China in recent 40 years were evaluated, which provided methods and data support for the realization of the biodiversity goal of SDG15 of the United Nations. Customize the special Portuguese agricultural monitoring system, carry out detailed agricultural monitoring training for Mozambique, and continuously provide solid technical support and decision support for promoting technological innovation in the field of earth big data and achieving SDGs goals.
