“…When ESI < 1, the corresponding product or process is not sustainable in the long term, when 1 < ESI < 5, the corresponding product or process has a sustainable contribution to the economy for medium periods and the product or process with ESI > 5 can be recognized as sustainable in the long term [6].…”

“…Finally, these flows are combined for the calculation of total emergy "U" and emergy indices (Fig. 3), which help to draw conclusions about system's performance -at this point, the ternary diagram as proposed by Giannetti et al (2006) and later described in detail by Almeida et al (2007) could be helpful for a graphical interpretation of the assessed systems.…”

“…The concept of ternary diagrams was proposed by Gibbs and Roozeboom for the analysis of mixed components and introduced into emergy synthesis by Giannetti et al [13]. The representation of emergy values on the ternary diagram allows prompt visualization of the results and facilitates comparison among provinces in PPRD.…”

Abstract:In this paper, emergy analysis is used in association with the ternary diagrams and geographic information system (GIS) tools to improve the evaluation of sustainability for the Pan-Pearl River Delta (PPRD) region. Emergy accounting of PPRD is estimated, and various emergy-based indicators are reported. Ternary diagrams are drawn to provide a graphical representation of the emergy accounting data. Finally, the GIS tools are employed to assist in the emergy-based spatial analysis, and emergy density based on flat land area is mapped to reflect the intensity of emergy use in human activity areas. Results show the following: (1) the current development path of the PPRD region, with the value of emergy sustainability index (ESI = 0.227) significantly lower than one, is unsustainable in the long run; (2) Guangdong has the lowest ESI value (0.071), and the ESI values of Fujian, Guangxi, Hunan and Jiangxi are lower than 0.5, indicating that the economy in these provinces overly relies on non-renewable and imported resources; (3) Guizhou has a high emergy yield rate and is thus the main energy supplier in PPRD; and (4) among the nine provinces in PPRD, only Hainan has an ESI value (2.145) higher than one.
