Special Issue Information

Dear Colleagues,

In a world where seas and oceans are overexploited and constitute bins for solid and liquid waste, with all the harmful consequences on flora, fauna, and the quality of marine waters, it is urgent to publish and raise public awareness for the defense and protection of the marine environment. Marine biodiversity is essential for meeting the world's food needs. Climate change is increasingly present in the world through the frequency of droughts and floods. Oceans are mitigators of these climate changes, hence the importance of conserving the marine environment and its biodiversity. All coastal countries are threatened and are called upon to contribute to preserving their living natural marine resources and also fighting climate change. Today's world is not only aimed at production, but also at conservation and sustainable development. Indeed, according to UNESCO, it is the Decade of the Oceans 2020–2030.

In this Special Issue, original research articles and reviews are welcome.  

I look forward to receiving your contributions.

In the context of occupational environments and sustainable employment, this review explores the effects of declining workers’ health, environmental degradation, and the depletion of marine resources on workers’ psychological well-being. As seas and oceans are increasingly exploited and used as dumping sites for both solid and liquid waste, marine ecosystems are severely degraded, with negative impacts on biodiversity, water quality, and ecosystem processes. Marine biodiversity is crucial to maintaining global food security and supporting the livelihoods of millions of people worldwide. Moreover, this study examines the role of digital technology in the marine industry in safeguarding workers’ sustainable well-being. It emphasizes the complementary roles of law and technology in promoting it. The risks to the health and well-being of marine workers are greatly increased by the occupational consequences of climate change on the sustainable environment and the effects of working in marine environments. Working conditions, incomes, and even unemployment among marine workers have been directly affected by the degradation of marine environments and the depletion of marine resources. Anxiety, panic, depression, rage, and other unpleasant emotions that affect workers’ health and pose mental health risks are detrimental to the psychological well-being of marine workers. The challenges of employment in the marine industry adversely affect the physical and mental well-being of marine employees and hinder economic growth. However, digital technology in marine environments has fundamentally altered the regulations governing marine operations. Full article

Endangered sea turtles are highly vulnerable to environmental pressures and human activities, resulting in major shifts in their population and distribution. Identifying and managing new nesting sites are essential for their reproduction and survival. This study identifies the presence of an unrecorded loggerhead turtle (Caretta caretta) nesting population at Ghedhabna Beach in Tunisia. A mixed-methods study based on intensive field monitoring over three consecutive nesting seasons (2023–2025) and interviews with 120 local residents was conducted to assess reproductive parameters and community perceptions of sea turtles. An annual mean of 39.33 ± 12.56 nests (range 30–54) and a mean nesting density of 3.93 ± 1.29 nests km−1yr−1 were recorded, highlighting Ghedhabna as the second most important loggerhead nesting site in Tunisia. Incubation durations suggested a potential male-skewed hatchling production, a key factor for the Mediterranean population sustainability under climate warming. The interviews revealed a history of consistent nesting activity in the area and a limited public awareness. The main threats to nesting success include marine debris, uncontrolled beach activities, and predation by the ghost crab (Ocypode cursor). The mixed ecological and social approaches highlighted the urgent need to develop sustainable conservation measures in this zone, based on integrated management, to mitigate existing pressures and ensure population resilience.
