The Current Green Economy Situations in European Union
Energy is undoubtedly one of the fundamental factors in the development of economies around the world. This is particularly evident during crises related to the reduction of supplies or the lack of energy sources. For example, the oil crisis of the 1970s of the twentieth century showed the problem of energy security, which has returned today and is one of the important topics of discussion in the European Union (EU) countries. Changes in the situation of the energy markets and geopolitical conditions show that the problem of energy security is fundamental for the functioning of modern economies. It directly influences economic development and other strategic areas, including the Lisbon Strategy for Growth and Jobs and the Millennium Development Goals.

The Development of Biogas Plants
Agricultural biogas plants have a long history, beginning with early advancements in biogas technology and its application in agricultural contexts. Throughout history, several societies have used organic waste to make biogas, a renewable energy source. However, modern agricultural biogas plants as we know them today have changed greatly as a result of scientific and technological advances.

The Development Process of DAUE
Driving analysis of urban expansion (DAUE) is usually implemented to identify the driving factors and their corresponding driving effects/mechanisms for the expansion processes of urban land, aiming to provide scientific guidance for urban planning and management. DAUE is defined to cover all related driving effect/relationship/mechanism research on urban expansion and includes the employed analysis methods within them, i.e., correlation analysis, regression analysis, causal analysis, and so on.

The Drivers and Barriers of Green Ports
Ports play an increasingly significant role in fostering regional economic growth and international trade as a key hub of the transportation network. Ports now provide cities, regions, and nations with a vital strategic resource for taking part in global economic cooperation and competitiveness, in addition to providing space for transportation, logistics, and a way to connect with the outside world. Green ports are presented as an achievable solution to the energy issue and environmental degradation. A green port is a port that not only satisfies environmental criteria but also provides economic benefits. Green ports are an excellent strategy to reduce environmental pollution and ecological harm, as well as to maintain the ports’ water resources and natural environment.

The Eco-Wellbeing Performance in China
After rapid development in recent decades, China has laid a strong economic foundation and established material conditions. Despite this, the country still confronts a range of challenges that impede higher-quality economic and social development. To measure high-quality regional development, eco-wellbeing performance (EWP) has become an important tool that seeks to strike a balance between economic development, human wellbeing, and environmental protection.

The Ecosystem Services of Temperate Wetlands
Wetlands constitute important habitats that provide several ecosystem services (ES). Wetlands have been termed the kidneys of the world for their water purification services and contain 20–25% of total soil organic carbon. Wetlands are among the ecosystems with the most valuable ES, with regulating services being the most important for inland wetlands.

The Effect of Biochar on Soil Properties
Biochar, a product of biomass pyrolysis, is recognized for its positive effects on soil fertility and carbon sequestration. Biochar acts as a soil conditioner, improving physical, chemical, and biological properties and enhancing soil fertility and crop yield. Furthermore, it aids in mitigating climate change by sequestering carbon dioxide. However, the long-term behavior of biochar and its interactions with various factors require further field research for optimal utilization, as the aging process of biochar in soil is complex, involving physical, chemical, and biological interactions that influence its impact on the agroecosystem.

The Existing Remote Sensing Index Resources
Remote sensing indices are widely used in various fields of geoscience research. However, there are limits to how effectively the knowledge of indices can be managed or analyzed. One of the main problems is the lack of ontology models and research on indices, which makes it difficult to acquire and update knowledge in this area.
