Currently, negotiation on global carbon emissions reduction is very difficult owing to lack of international willingness. In response, geoengineering (climate engineering) strategies are proposed to artificially cool the planet. Meanwhile, as the harbor around one-third of all described marine species, coral reefs are the most sensitive ecosystem on the planet to climate change. However, until now, there is no quantitative assessment on the impacts of geoengineering on coral reefs. This study aims to model the impacts of stratospheric aerosol geoengineering on coral reefs.

The HadGEM2-ES climate model is used to model and evaluate the impacts of stratospheric aerosol geoengineering on coral reefs.

This study shows that (1) stratospheric aerosol geoengineering could significantly mitigate future coral bleaching throughout the Caribbean Sea; (2) Changes in downward solar irradiation, sea level rise and sea surface temperature caused by geoengineering implementation should have very little impacts on coral reefs; (3) Although geoengineering would prolong the return period of future hurricanes, this may still be too short to ensure coral recruitment and survival after hurricane damage.

This is the first time internationally to quantitatively assess the impacts of geoengineering on coral reefs.

The purpose of this paper is to review cases of artificial reefs built through additive manufacturing (AM) technologies and analyse their ecological goals, fabrication process, materials, structural design features and implementation location to determine predominant parameters, environmental impacts, advantages, and limitations.

The review analysed 16 cases of artificial reefs from both temperate and tropical regions. These were categorised based on the AM process used, the mortar material used (crucial for biological applications), the structural design features and the location of implementation. These parameters are assessed to determine how effectively the designs meet the stipulated ecological goals, how AM technologies demonstrate their potential in comparison to conventional methods and the preference locations of these implementations.

The overview revealed that the dominant artificial reef implementation occurs in the Mediterranean and Atlantic Seas, both accounting for 24%. The remaining cases were in the Australian Sea (20%), the South Asia Sea (12%), the Persian Gulf and the Pacific Ocean, both with 8%, and the Indian Sea with 4% of all the cases studied. It was concluded that fused filament fabrication, binder jetting and material extrusion represent the main AM processes used to build artificial reefs. Cementitious materials, ceramics, polymers and geopolymer formulations were used, incorporating aggregates from mineral residues, biological wastes and pozzolan materials, to reduce environmental impacts, promote the circular economy and be more beneficial for marine ecosystems. The evaluation ranking assessed how well their design and materials align with their ecological goals, demonstrating that five cases were ranked with high effectiveness, ten projects with moderate effectiveness and one case with low effectiveness.

AM represents an innovative method for marine restoration and management. It offers a rapid prototyping technique for design validation and enables the creation of highly complex shapes for habitat diversification while incorporating a diverse range of materials to benefit environmental and marine species’ habitats.

Mobile games and ICT-based mixed reality tools offer significant opportunities for tourism. This chapter reviews the existing literature in both these areas, and presents a novel way of combining games and virtual reality into an interpretive tool. As a complex, threatened marine ecosystem, Australia’s Great Barrier Reef faces significant interpretive challenges, and almost no new interpretive tools have been developed over the last 30 years. Here, the authors unpack the stages and interdisciplinary approach required to design the tool and highlight how it might fit within the broader scope of ICT developments in tourism. We outline areas of future research, with a particular focus on how ICT might contribute to making nature-based tourism more sustainable, by finding fun, innovative ways to engage tourists in the conservation of some of our most iconic natural assets.

The purpose of this paper is to prove and qualify the influence of textured surface substrates morphology and chemical composition on the growth and propagation of transplanted corals. Use additive manufacturing and silicone moulds for converting three-dimensional samples into limestone mortar with white Portland cement substrates for coral growth.

Tiles samples were designed and printed with different geometries and textures inspired by nature marine environment. Commercial coral frag tiles were analysed through scanning electron microscopy (SEM) to identify the main chemical elements. Raw materials and coral species were selected. New base substrates were manufactured and deployed into a closed-circuit aquarium to monitor the coral weekly evolution process and analyse the results obtained.

Experimental results provided positive statistical parameters for future implementation tests, concluding that the intensity of textured surface, interfered favourably in the coralline algae biofilm growth. The chemical composition and design of the substrates were determinant factors for successful coral propagation. Recesses and cavities mimic the natural rocks aspect and promoted the presence and interaction of other species that favour the richness of the ecosystem.

Additive manufacturing provided an innovative method of production for ecology restoration areas, allowing rapid prototyping of substrates with high complexity morphologies, a critical and fundamental attribute to guarantee coral growth and Crustose Coralline Algae. The result of this study showed the feasibility of this approach using three-dimensional printing technologies.

The purpose of the study is to reviewing community empowerment in ecological conservation through the Coral Reef Rehabilitation and Management Program (COREMAP). This research is under a governance perspective, namely transparency, accountability and community participation in Bahari Village, South Buton District, Indonesia.

Data were collected in three ways: they are interviews, observation and documentation. Data were analyzed using qualitative descriptive methods.

The empowerment of coastal village communities through the COREMAP program is not fully managed properly referring to the principles of transparency, accountability and participatory. In addition, the role of stakeholders is not maximal, where the government and the companion are not able to provide solutions to the problem of community empowerment while the apathetic community in the implementation of empowerment program. So that empowerment does not fully have a positive impact on coastal communities. While the sustainability of the empowerment program is threatened with failure, which has an impact on COREMAP's environmental damage and coastal communities.

The originality of this research is that the study was conducted on coastal communities in ecological conservation through the COREMAP program in Bahari Village, South Buton Regency.

Ethical consumption exemplifies thinking locally and acting globally, and the political economy in which it exists makes its ethics problematic. This chapter uses ecotourism to illustrate two aspects of thinking locally in ethical consumption. One is the local institutions and practices that this form of consumption reflects, embodied in the Western commercial capitalism that provides what Westerners consume ethically. Ethical consumption extends the reach of that local capital and its logic. The second is the local understandings and values it reflects, embodied in the desires of ethical consumers and met by commodity producers and the institutions that influence them. Ethical consumption does not, however, only impose local institutions and values globally; but it also shapes local consumers, by portraying individual market choice as an appropriate vehicle for bringing about an ethical world, thereby diverting attention from other sorts of ethical action.

During the great post–World War II economic expansion, modernization theorists held that the new American capitalism balanced mass production and mass consumption, meshed profitability with labor's interests, and ended class conflict. They thought that Keynesian policies insured a near full-employment, low-inflation, continuous growth economy. They viewed the United States as the “new lead society,” eliminating industrial capitalism's backward features and progressing toward modernity's penultimate “postindustrial” stage.⁷ Many Americans believed that the ideal of “consumer freedom,” forged early in the century, had been widely realized and epitomized American democracy's superiority to communism.⁸ However, critics held that the new capitalism did not solve all of classical capitalism's problems (e.g., poverty) and that much increased consumption generated new types of cultural and political problems. John Kenneth Galbraith argued that mainstream economists assumed that human nature dictates an unlimited “urgency of wants,” naturalizing ever increasing production and consumption and precluding the distinction of goods required to meet basic needs from those that stoke wasteful, destructive appetites. In his view, mainstream economists’ individualistic, acquisitive presuppositions crown consumers sovereign and obscure cultural forces, especially advertising, that generate and channel desire and elevate possessions and consumption into the prime measures of self-worth. Galbraith held that production's “paramount position” and related “imperatives of consumer demand” create dependence on economic growth and generate new imbalances and insecurities.⁹ Harsher critics held that the consumer culture blinded middle-class Americans to injustice, despotic bureaucracy, and drudge work (e.g., Mills, 1961; Marcuse, 1964). But even these radical critics implied that postwar capitalism unlocked the secret of sustained economic growth.

The recent advent of large scale, self‐contained, resort type tourism centers about the world is a function not only of the focussing effect of mass air travel by jet airplane, package tour marketing mechanisms and the increase in affluence and leisure time in urban areas, but also is predicated upon a new kind of comprehensive ‘city planning’ and a new approach to resort community development, embracing, inter‐alia a holistic, total systems and ‘environmental design’ concept.

Waste in the marine environment has become a serious task to be managed. Uncontrolled dumping creates large amounts of methane gas contributing to greenhouse gas emissions. This conceptual paper focuses on the role of community in waste management activities to reduce carbon emissions in the marine environment. Hence, this paper aims to examine using literature, the various roles of community, types of marine waste and its impact on carbon emissions and climate change.

The paper is based on evaluation and criticism from previous studies and provides a hypothetical understanding of the human contribution to climate change, and its impacts which will increasingly affect climate change and sustainable tourism.

The results from this study can be used as a guide for policy makers to help improve community participation and public engagement in efforts to reduce the levels of waste in the marine environment. This is especially critical in rural tourism destinations where the impact of uncontrolled marine waste has serious consequences for the tourism industry.

The paper contributes to a better understanding of the role of community in mitigating waste to attain a higher quality of tourism experience and environmental benefits from emission level reductions.
