Journal of Environmental Management

The Journal of Environmental Management is a peer reviewed journal for the publication of original research related to managing environmental systems and improving environmental quality. All papers submitted to the journal must show a distinctive link with environmental management applications. Specific area of interest for the journal include: • Development of technologies intended for applications to environmental ecosystems (water, air, soil) • Natural resource management • Ecological applications or conservation • Management and valorisation of waste (including industrial residues and effluents) • Development of methods for environmental quality management (new procedures, characterization techniques, monitoring methods, governing standards, etc.) • Environmental system modelling and optimization • Environmental analysis and assessment (environmental impact assessment, risk assessment, life cycle analysis, material flow analysis, life cycle costing, emission accounting, etc.) • Social, economic and policy aspects of environmental management Case studies are welcome when the authors indicate the wider applications of their insights or techniques, emphasizing the global perspective of the problem they address. As governments and the general public become more keenly aware of the critical issues arising from how humans use their environment, this journal provides a forum for the discussion of environmental problems around the world and for the presentation of management results. It is aimed not only at the environmental manager, but at anyone concerned with the sustainable use of environmental resources.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
