River flow reconstruction under the background of long-term climate change is of great significance for understanding the regional response to future drought and flood disasters, and the sustainable development of water resources. Investigating the basic characteristics and changing trends of the streamflow of the Ganjiang River is scientifically important to mitigate drought and flood disasters in the future. This study reconstructed drought and flood grade series of five regional stations of the Ganjiang River based on spatially explicit and well-dated local chronicle materials and used a linear regression model of modern drought/flood grades and precipitation to reconstruct historical precipitation for the past 515 years. The relationships between the modern precipitation of five regional stations and streamflow of Waizhou Station, which is the last hydrological station of the Ganjiang River were analyzed through principal component regression. The adjusted R2 is 0.909, with a low relative bias of −1.82%. The variation of streamflow from AD 1500 to AD 2014 was reconstructed using the proposed model. Result shows that high flows occur in nine periods and low flows occur in 11 periods. Extremely low stream flow in 515 years appears during the middle and late 17th century. Cumulative anomaly and Mann-Kendall mutation test results reveal that a transition point from predominantly low to high flows occur in AD 1720. Redfit power spectrum analysis result shows that the variation periods of streamflow are 2–5, 7–8 years, and approximately 32 years, where the most significant period is 2–3 years. Continuous wavelet transform indicates that the corresponding relation occurs between streamflow and El Niño/Southern Oscillation for eight years. Streamflow is affected by temperature and East Asian monsoon that is controlled by solar activities. The flood may be related to strong solar activity, monsoon failure, and vice versa. Hydrological frequency curve analysis shows that the streamflow of the Ganjiang River once in a hundred years may reach up to 1031 × 108 m3 for flood or 485 × 108 m3 for drought and the standard of once in a millennium runoff may reach up to 1188 × 108 m3 for flood or 450 × 108 m3 for drought. These results may provide basic hydrological data for the sustainable development of society and serve as a reference for mitigating the impact of drought and flood disasters in the future.

Under the slogan “Our heritage: where the past meets the future”, European Union has declared 2018 as the European Year of Cultural Heritage in an unprecedented attempt to enable people to become more interested in and involved with the cultural heritage, and to recognize its universal value and importance in the future development of the individuals, communities and societies. In spite of an increased acknowledgement and extending capitalization, the employment of the cultural heritage, in its tangible and intangible forms, as an asset the local communities may benefit from is still limited. The contribution of the cultural heritage to the sustainable development remains less relevant and illustrates the extent toward which individuals and the local communities, consequently societies, are able to preserve, promote and make the most of this forgotten resource. Paper explores the connections between the cultural heritage, marketing and the sustainable development of the local communities based on the secondary data regarding the involvement, perceived importance, access and participation related to the cultural heritage in order to assess if local communities grasp and consider the potential of this heritage to support their sustainable development through of an appropriate marketing effort. Keywords: Cultural heritage, sustainable development, local communities, marketing

Recently, the world is witnessing a severe global health issue owing to the COVID 19 pandemic, initially encountered at the city of Wuhan in Hubei province in China.  It spread rapidly, so do the fatality ratio. This pandemic has jeopardized the sustainable development goals at large. Still, the future is uncertain. The current study aimed to serve a multi-fold objective. First is to review the past literature on the coronavirus family to map our current understanding of its epidemic outbarks and to overview its social, environmental, and economic impact. Finally, to provide future agenda for policymakers to restrain the sustainable development goals. We used Scopus and Web of Science (WoS) databases for the systematic literature review process. We followed a strict screening process recommended in the PRISMA guidelines for the screening and quality assessment of systematic literature review. Final 51 studies were included for the systematic literature review. A systematic review of the past literature identified severe acute respiratory syndrome coronavirus (SARS), Middle East Respiratory Syndrome Coronavirus (MERS), bovine Coronavirus, canine Coronavirus, and feline Coronavirus are the significant classifications of the Coronavirus family discuss in the literature. We highlighted the potential pitfalls in the past literature, mainly serious scarce of collaborative and multidisciplinary research on the pandemic, although several researchers in the past highlighted the issue. However, these studies were mostly in a lab setting and experimental design. We provided a framework for a pandemic strategic response plan through multidisciplinary research to mitigate the impact of the recent COVID-19 pandemic and to be prepared for future episodes.

Evidence of how history and culture have been or should be harnessed to promote sustainability in remote and rural communities is mounting. To be sustainable, development must come from within, it must serve future generations as well as those in the present and it must attend to the vitality of culture, society, the economy and the environment. Historical research has an important contribution to make to sustainability, especially if undertaken collaboratively, by challenging and transcending the boundaries between disciplines and between the professional researchers, communities and organisations which serve and work with them. The Sustainable Development Goals’ motto is ‘leaving no one behind’, and for the 17 Goals to be met, there must be a dramatic reshaping of the ways in which we interact with each other and with the environment. Enquiry into the past is a crucial part of enabling communities, in all their shapes and sizes, to develop in sustainable ways. This article considers the rural world and posits that historical enquiry has the potential to deliver insights into the world in which we live in ways that allow us to overcome the negative legacies of the past and to inform the planning of more positive and progressive futures. It draws upon the work undertaken with the Landscapes and Lifescapes project, a large partnership exploring the historic links between the Scottish Highlands and the Caribbean, to demonstrate how better understandings of the character and consequences of previous development might inform future development in ways that seek to tackle injustices and change unsustainable ways of living. What we show is how taking charge of and reinterpreting the past is intrinsic to allowing the truth (or truths) of the present situation to be brought to the surface and understood, and of providing a more solid platform for overcoming persistent injustices.
