as the manufacturing industry gains momentum around the world, the conflicts between its rapid development and the accompanying consumption of materials, discharge of wastes and ecological impacts spiral. Governments around the world have explored measures and made achievements in alleviating the dual pressures from economic growth and environmental degradation. As for the overall trend of the manufacturing industry, creating and developing “green manufacturing” brands is the only way for the manufacturing industry to achieve further development. It is of great significance to design guidelines for green manufacturing from the angle of branding, the green notion provides more profundity and the soul to brands, ensuring sustainable development of brands. The development of green brands in Xiamen has adopted a global vision and related to the local realities, which would provide lessons for high-quality development of green manufacturing brands in other places.


Tourism, a multi-dimensional and multi-faceted activity with diverse social, cultural, economic and ecological impacts, got evolved as one of the largest and most significant economic sectors in the world. The lure of tourism as an engine of economic growth and diversification has been urging each and every country in the world to develop and promote it in the most possible manner (Dileep, 2018). As per the current projections, tourism is tend to grow further and it will remain as one of the most vibrant, growing and economically useful activities in the world having wide social and cultural ramifications in the years to come as well. Being an amalgam of industries, this sector includes a diverse range of industries like, intermediaries; transportation; accommodation; entertainment and recreation; shopping; hospitality; and infrastructure. Complex linkages and interrelationships exist among the various individual sectors of the tourism industry. The post second world war era has witnessed tremendous growth of tourism and in the same era has recorded the evolution and growth of information and communication technology as well. Information Technology has become one of the most fundamental and vital components of the successful businesses and organizations and is a major facilitator. In the growth of tourism as a major social phenomenon in the 21st century, Information and communication technology (ICT) too had played significant roles. Indeed, the relationship between tourism and ICT was symbiotic as well, since the latter sector got many opportunities for the application of it in the tourism sector, like in the air transportation which was a pioneer in developing transaction systems for handling the cumbersome booking data in the 1950s and 60s. Information systems for the core of ICT applications in businesses and organisations. Tourism Sector too has been using different types of information systems intensively in the international scenario. Kerala, one of the late entrants in the international tourism, has turned to be successful international tourist destinations within a few decades of time. The number of tourism arrivals has been registering consistent growth and the industry got expanded exponentially in Kerala. To compete globally, tourism of anywhere requires a variety of information systems. Kerala tourism industry is also not an exception to this. In this context, a study on the current usage of information systems in the tourism sector in Kerala seems inevitable. The study has to focus upon the types of information systems used by the tourism industry in Kerala, efficiency as well as the impacts of the usage of such information systems by the industry, comparing the scenario with the international standards and also to discuss about the future to suggest suitable solutions to look ahead to have more competence by the Kerala tourism

AbstractInvasive freshwater crayfish are spreading rapidly across the world. Here, we report the first record of Australian redclaw crayfish, Cherax quadricarinatus (von Martens 1868) in Hong Kong, China. Identification of the captured crayfish was confirmed using external morphological features and molecular analyses. A total of 49 crayfish were captured from a stream pool and a reservoir in Pok Fu Lam Country Park using dip nets and funnel traps. The captured C. quadricarinatus ranged from 17.20 mm to 56.40 mm (mean = 30.70) in carapace length and the sex ratio was 1:1. Since this species is globally recognized as an invasive species, a comprehensive survey on its status and invasion front, an investigation into its potential ecological impacts, as well as the formulation of a monitoring and removal strategy, are warranted.

This paper contributes to an in-depth understanding of how the mega-event contributes glurbanization of entrepreneurial city through a case study of Expo 2010 in Shanghai. It argues that spatial-related transformation is central to mega-event approach to glurbanization yet the soft power building is uncertain. It implies that the domestic impacts of mega-events are likely to be more profound than their global influences. This corresponds to the capitalist transformation from Fordist-Keynesianism to neoliberalism, in which mega-events such as Olympic Games and World Exposition have increasingly been incorporated into urban development plan to boost urban agenda. Although the profile of world fairs is reduced and does not have the international impacts that they used to have, Shanghai Expo 2010, the first Expo ever held in a developing country, is pinned hope on as the “Turn to Save the World Expo” and is unusually ambitious to bring opportunities in urban transformation. With a well-developed framework of glurbanization entailed by entrepreneurial city, this research enriches glurbanization theory by a thorough examination of Shanghai Expo. It finds that Expo-led landscape reconfiguration, spatial restructuring, and new sources provision effectively transformed Shanghai, propelling glurbanization in diminutive spatial scale. Yet, it remains powerless to impress the world as the voice of domestic propaganda is limited in the Western mainstream media. In all, the Expo case well exemplifies the power of mega-event approach to advancing local agenda, especially in spatial transformation per se, as well as its constraints in (re)shaping a global discourse.

In this series, entitled home/land, documentary photographs by Christopher Cowperthwaite provide the foundation for works that are meditations on the disruptions – cultural, political, and ecological – that result from conflict and crisis. The paintings present fragmentary images of the construction of the Israel-Palestine separation wall (and its concomitant fragmentation of the land), which are fused with collaged images from other conflicts and other times, asking the viewer to consider how an ever-deepening palimpsest of conflicts has become etched in our collective memory and on the surface of the earth since the World Wars. I created this series as an attempt engage my artistic practice with the complex history and contemporary reality of globalized conflict, which, via globalized media, has become imbricated with the flow of our daily lives and thoughts. As a Canadian artist and educator, I have no direct contact with the daily crises occurring in conflict zones, yet I am impelled to respond creatively, to translate my affective response to these global catastrophes into a visual elegy and a plea for awareness of the human and ecological impacts of warfare.

Bushfires are common events in Australia reaching their peak each summer season. However, the last bushfire season from July 2019 until March 2020 was unprecedented. An estimated area between 240,000 up to 400,000 km² burned, with the southeast coast being particularly affected. The images of burnt flora and fauna and the fires that raged for months went around the world. It became clear how vulnerable both Australia’s communities and ecosystems are to this natural hazard, which is becoming more frequent and intense. Australia’s southeast is increasingly vulnerable against the often sudden event of bushfires. This article discusses the current trends, causes for this extreme fire season, the socio-economic and ecological impacts, and the resulting adaptation processes.

Coral reefs everywhere are under increasing pressure from a suite of stressors. Recently, threats associated with climate change have been brought closer into focus and now dominate discussions and debate relating to the coral reef crisis (Hughes et al. 2003, Hoegh-Guldberg et al. 2007). Indeed, mitigating local stressors on coral reefs has been given less priority and publicity than the global need to reduce greenhouse gas emissions. Interestingly though, recent surveys demonstrate that most reef scientists agree that coral reefs are under greater threat from impacts associated with human population growth, coastal development, and overfishing than from global climate change (Kleypas and Eakin 2007). This is especially true for the reefs in SE Asia and the Pacific, which make up the bulk of the reefs in the world (Bryant et al. 1998). In these areas, regulations to ensure that anthropogenic activities near and on coral reefs are conducted sustainably, such as development, sanitation, fishing and even tourism; either do not exist or are rarely enforced due to a lack of resources. Here, we present one such example from Indonesia, one of the most densely populated countries in the world, a country where over 60% of the population relies in some way on marine resources.

Abstract Recognition that hydropower plays a role in fostering sustainable development and helping countries move away from fossil fuels has led to a resurgence of planned projects on transboundary rivers around the world. Whilst these projects offer clear benefits, they are not without their socio-ecological impacts. An added feature of hydropower projects is that they tend to involve a wide range of actors that are responsible for their financing, planning, construction and operation (international and domestic; private and State). This begs the question, if it is ultimately the responsibility of States to ensure that these projects are in accordance with international law obligations, what does that responsibility entail when much of the activity is conducted by private companies? International law has a long tradition of placing States under an obligation to regulate the conduct of non-State activities so as to prevent transboundary harm. However, a closer review of the law relating to transboundary hydropower projects reveals that more could be done to guide States as to the appropriate measures that they might put in place to ensure that any hydropower projects involving private actors are implemented in an equitable and sustainable manner.
