“…Highly intense mining practices can lead to environmental degradation, which includes deforestation, damage to ecosystems and water contamination (Worlanyo & Jiangfeng, 2021). These consequences have far-reaching ecological implications that affect the sustainability of ecosystems, which may require years to heal (Saint-Amand et al, 2022).…”

This study aims to investigate the impact of climate policies, such as the ParisAgreement and its derivatives, the Gasglow climate pact, on the reference coal priceand its effect on the volume of Indonesian coal exports. A qualitative approach,utilizing secondary data from various international level journals, data from theMinistry of Energy and Mineral Resources, the World Bank, and other relevantsources, was employed. The research method utilized literature study. The results ofthis study indicate Climate policies the Paris Agreement, the Glasgow Climate Pact,and benchmark coal price on Indonesia's coal export volume is limited do not have anotable effect the volume of coal exports do not significantly impact the reference.Recommendation for Policy makers should conduct a comprehensive assessment ofcoal export policies, with a particular focus on their alignment with the commitmentsoutlined in the Paris Agreement and the Glasgow Climate Pact. This assessmentshould include an examination of emissions targets and whether or not coal exportsare at odds with them.

“…In this study, we use the 2D barotropic unstructured-mesh ocean model SLIM (Lambrechts et al, 2008). SLIM has already been applied multiple times to the GBR for connectivity, sediment transport and plastic pollution studies (e.g., Lambrechts et al, 2010;Thomas et al, 2014Thomas et al, , 2015Critchell et al, 2015;Grech et al, 2016;Schlaefer et al, 2022;Saint-Amand et al, 2022).…”

Coral reef environments are biodiversity hotspots that provide many services to coastal communities. They are currently facing an increasing anthropogenic pressure that jeopardises their survival. Numerical ocean models are an important tool to understand the functioning of coral ecosystems and the mechanisms ensuring their resilience. However, simulating the water circulation through reef systems is challenging because of their naturally complex topography and bathymetry. Many ocean models used for such applications have a spatial resolution coarser than the scale of individual reefs, which puts into question their suitability for the task. Here, we assess the sensitivity of a coastal ocean model's outputs to its spatial resolution when simulating the water circulation in the entire Great Barrier Reef (Australia), the largest coral reef system in the world. We consider the same model with five different resolutions near reefs, ranging from 250 m to 4 km, and compare the model outputs at different locations around reefs and in the open ocean. We also simulate the transport of passive particles released from those different locations. Our results show that the simulated tidal signal is similar for all five resolutions. However, strong discrepancies (> 10 cm/s) in the current velocity are observed near the reefs and along the rugged coastline. When using a coarse-resolution model, the amplitude of the currents is overestimated over reefs, and underestimated between them. We find that validating the model at deep water mooring sites is not sufficient to ensure it performs well close to reefs. Discrepancies in currents lead to more directional and uniform tracer dispersal patterns on coarse-resolution meshes that contrast with the more dispersive patterns observed on fine-resolution meshes. Those differences at the reef level have a large cumulative effect when simulating transport processes over several weeks. Our results suggest that ocean circulation and transport simulations in coral reef environments should be based on model resolutions finer than the reef scale, which generally means a maximum resolution of about 250-500 m.

“…For instance, large hydropower and mega urban development projects often cause long-term social controversies, displacement and environmental degradation, exacerbating social inequalities (Khanal et al, 2021;Wang and Wu, 2019). Major coal mining megaprojects can have ripple effects on ecosystems, posing direct and deadly threats to marine life and cascading impacts on geological stability and fisheries (Saint-Amand et al, 2022). There will be increasingly complex megaprojects worldwide in the foreseeable future (Ma and Fu, 2022;Thounaojam and Laishram, 2022).…”

PurposeMegaprojects can play a crucial role in achieving Sustainable Development Goals (SDGs) and tackling Global Challenges. However, they are often criticized for their massive resource consumption, poor cost/time performance and significant social-environmental impacts, including irreversible environmental damage. This study aims to chart the evolution of research on megaprojects sustainability and to offer a roadmap for future developments.Design/methodology/approachThis study adopted a systematic literature review (SLR) to identify emerging themes and gaps. This study follows a three-step process of planning, conducting and reporting, based on the Tranfield approach. The overview of megaprojects sustainability research was captured through bibliometric analysis. In addition, content analysis was carried out to reveal the development of this field and get an insight into the future directions towards sustainability transition.FindingsThis study provides a longitudinal, in-depth analysis of megaprojects sustainability studies. Drawing on sustainability science and project management theories, we introduce a three-dimensional analytical framework consisting of sustainability, scope and stakeholder. This framework explains the evolution of megaprojects sustainability research from sustainability of megaprojects, to sustainability for megaprojects and then to sustainability by megaprojects. Three future avenues are proposed: (1) SDGs orientation at multi-level; (2) scope enlargement at temporal and spatial scales and (3) inclusive development for stakeholders.Originality/valueThis research contributes to the literature by providing a comprehensive and forward-looking analysis of megaprojects sustainability research. The framework and three research agendas provide a comprehensive picture of megaproject sustainability research; the agenda for future research is intended to inspire more studies and disruptive actions towards sustainability transition.
