The world is undergoing tremendous changes, and food security is encountering major challenges in China and even the world. In order to systematically study globalization and explore its new patterns, new issues and new paths for food security, we interviewed ten distinguished professors from different fields and discussed hot topics, including the potential for increasing farmland production, agricultural water and soil resources and food production, food waste, international agricultural product trade, stable supply of key agricultural product, global agricultural food system, dual circulation pattern and corporate actions, global food production and consumption, international food security governance, and cutting-edge research on food safety. The result shows that the global agricultural food system has entered an era of complexity and high risk. International food security governance is facing challenges in terms of resources, binding force and action power. We are facing an increasing pressure of import dependent agricultural products to ensure stable supply. It is necessary to deepen supply-side reform and strengthen demand-side management so as to guarantee national food security. New changes have taken place in globalization. This will test China's ability to deepen agricultural opening-up, participate in global food security governance, and achieve national food security. In the face of complex international and domestic situations, for better national food security governance, it is necessary to adhere to system thinking and coordinate domestic and international markets. It is also very important to target the entire industry chain, emphasize risk control, and handle the relationship between the government and the market. Furthermore, researchers need to explore the internal relationships and specific mechanisms between food security and other important issues, such as food systems, ecosystems, high-quality development goals, agricultural opening-up, and new dual-circulation development patterns. This could provide a scientific reference for establishing and improving the national food security strategy of "featuring self-sufficiency based on domestic grain production, guaranteed food production capacity, moderate imports, and technological support" in the New Era.
Due to the particularity of natural environment and geographical location, the human settlement environment of the Yellow River Basin is in a complex process of constant changes and is always facing severe challenges. The coupling process of human environment space with natural and social elements originates from the dynamic, comprehensive and systematic adaptation mechanism presented in the process of human-land relationship change, so revealing the system adaptation mechanism is the key to solve the human environment dilemma in the Yellow River Basin. Therefore, based on the perspective of "locality and adaptability", this paper invited experts and scholars from Qinghai, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan and Shandong along the Yellow River and other provinces. They interpreted the characteristics of human settlements in the Yellow River Basin from the perspectives of natural geography, social economy, urban and rural development, and heritage protection, and sought sustainable strategies to adapt to China's new urbanization path. The main points are stated as follows: On the whole, the adaptability of human settlements in the study area has multi-scale spatial correlation and historical geographic dependence. The Yellow River Basin has an important ecological function, but the natural environment in different regions is facing such problems as land salinization, soil erosion and pollution, etc., so it is necessary to promote the greening of human-land coupling relationship. The Yellow River Basin, especially the cities along the upper reaches of the river, have distinct characteristics of openness, ethnic cultural diversity and integration. Due to the complex natural environment, caves and other special settlements have been formed in the middle and upper reaches of the Yellow River. In the process of rapid urbanization, they are faced with transformation and disappearance, retaining the cultural genes of traditional settlements, and it is urgent to classify and treat them differently to promote their healthy evolution. The internal and external radiation drive of urban agglomeration in the Yellow River Basin is the foundation of high-quality development throughout the river basin, and the optimization and upgrading of urban structure is an important way to promote high-quality development. To achieve sustainable development, scientific and technological innovation and industrial structure transformation and upgrading are also needed.
In the context of unprecedented changes of energy geopolitics, China's current energy situation is becoming increasingly complex, and energy security has become a major strategy for national economic development. Under the new situation, not only the scientific issues, research objects, and research methods of the world energy geography and national energy security at the interdisciplinary perspective, but also the global energy governance system and international energy cooperation based on the actual needs of China are worth discussion among experts and scholars. This article uses the form of "question and answer (Q&A)" to provide a panoramic view of the host and nine academic interviewees based on different perspectives. Experts express their opinions in a range of content, including energy security and global energy governance model, the challenges and countermeasures of China's energy security, the new changes of global energy geopolitics, the energy security under the geographical pattern of unequal world energy production and consumption space, the high-quality development of China's energy under the trend of global low-carbon transformation, changes in the global energy supply and demand pattern affected by major public health emergencies, and future research prospects and important research directions of energy geography. We hope that a certain consensus can be reached, so as to better promote the development of the discipline of world energy geography, as well as actively respond to issues such as the unprecedented change of energy geopolitics and national energy security.
