Energy security usually considers both the stability of energy supply and security of energy use and it is receiving increasing attention globally. Considering the strategic importance and sensitivity to international change of the crude oil supply, we decided to examine China’s energy...

The evaluation of ecosystem health in urban clusters will help establish effective management that promotes sustainable regional development. To standardize the application of emergy synthesis and set pair analysis (EM–SPA) in ecosystem health assessment, a procedure for using EM–SPA models...

Waste management is a distinct practice aimed at reducing its effects on health and the environment and increasing energy and material recovery. The urban waste management industry has been slow to adopt new technologies, such as sanitary landfills and incineration, which enable better treatment...

The resilience of the phosphorus (P) cycling network is critical to ecosystem functioning and human activities. Although P cycling pathways have been previously mapped, a knowledge gap remains in evaluating the P network’s ability to withstand shocks or disturbances. Applying principles of...

Not only insufficient water quantity, but also inadequate water quality can pose constraints on agricultural production and result in potential economic losses. Such economic losses in agriculture may adversely impact downstream producers through reduced input supplies. In this study, we...

Energy consumption has always been a central issue for sustainable urban assessment and planning. Different forms of energy analysis can provide various insights for energy policy making. This paper brought together three approaches for energy consumption accounting, i.e., energy flow analysis...

Hydropower is the major renewable energy source for many nations and regions. Dam construction caused direct or indirect detrimental impacts on river systems by altering the water flow pattern and reshaping natural habitats. The dam-induced environmental impact assessment is critical in...

Biogas engineering and the biogas-linked agricultural industries as a whole has been used as both a developmental strategy for rural new energy and an important part of renewable agriculture revolution in China. In this paper, we proposed a 3-level emergetic evaluation framework to investigate...

The biogas-linked agriculture has experienced a rapid development in recent years in rural China, which serves both as part of the country's developmental strategies of cleaner energy and an important reaction to sustainable agriculture call. This paper provides an overview of the economic and...
