Sustainable hotel strategy execution : a review and way forward

CITATION: Migale, H., Stimie, J. & Brent, A. 2019. Sustainable hotel strategy execution : a review and way forward. South African Journal of Industrial Engineering, 30(4):102-117, doi:10.7166/30-4-2025.The original publication is available at http://sajie.journals.ac.zaTourism, the third largest industry in the world, is worth US$ 1.4 trillion, and represents 10 per cent of the world’s GDP. Tourism is also responsible for five per cent of the world’s carbon dioxide emissions, of which hotels and other types of accommodation account for one per cent. In this context, a sustainable hotel strategy execution is essential for maintaining and improving our planet’s socio-economic and ecological balance. This systematic review lays the foundation for the development of a sustainable hotel strategy decision and execution support tool. Systems thinking and system dynamics allow the modelling of the interdependent elements of a complex hotel system, followed by a scenario simulation for proper strategy–analysis and strategy-decision. The execution of the chosen strategy can then be compared with the expected results. With a view to appraising the potential development of such a sustainable hotel strategy execution model for any tourism destination, a systematic literature review was carried out on existing sustainable strategy execution models and tools, as well as the existing use of systems thinking and system dynamics in the tourism and hotel sector.http://sajie.journals.ac.za/pub/article/view/2025Publisher's versio

Hydro-institutional mapping in the Steelpoort River Basin, South Africa

Volume 1 of the study on Hydro-Institutional Mapping of the Olifants River Basin. This study aims to give an overview of water users and influences on water use by institutions in the Steelpoort river basin, a sub-basin of the Olifants. Describes a general methodology and framework for setting out the HIM for a river basin and presents findings from case studies in the basin. The hydro-institutional interactions among all types of water users in a South African river basin are also described

Substantial variation in the extent of mitochondrial genome fragmentation among the blood-sucking lice of mammals

Challenges in cultivating microorganisms have limited the phylogenetic diversity of currently available microbial genomes. This is being addressed by advances in sequencing throughput and computational techniques that allow for the cultivation-independent recovery of genomes from metagenomes. Here, we report the reconstruction of 7,903 bacterial and archaeal genomes from >1,500 public metagenomes. All genomes are estimated to be ≥50% complete and nearly half are ≥90% complete with ≤5% contamination. These genomes increase the phylogenetic diversity of bacterial and archaeal genome trees by >30% and provide the first representatives of 17 bacterial and three archaeal candidate phyla. We also recovered 245 genomes from the Patescibacteria superphylum (also known as the Candidate Phyla Radiation) and find that the relative diversity of this group varies substantially with different protein marker sets. The scale and quality of this data set demonstrate that recovering genomes from metagenomes provides an expedient path forward to exploring microbial dark matter.The recovery of 7,903 bacterial and archaeal metagenome-assembled genomes increases the phylogenetic diversity represented by public genome repositories and provides the first representatives from 20 candidate phyla
