Abstract

Throughout the COVID-19 pandemic, numerous abuses of labour rights of seafarers have been reported within international community. Seafarers’ rights, stipulated in Maritime Labour Convention of 2006, were violated by bans on going ashore in harbours, as well as by abandonment by seafarers’ employers after the end of contracts, partly as a result of national lockdowns. The Convention, aimed at creating a comprehensive regulation on maritime labour issues, including medical care and health protection, proved to be insufficient to safeguard proper working conditions of seafarers. Consequently, it is necessary to evaluate implementation of the Convention in the period of pandemic, for the purpose of taking into account knowledge and best practice developed in this period in further amendments to the Convention.

Abstract

Transition of the global energy sector is in progress. The share of renewable energies has increased over time and achieved 36.6% of global electricity capacity in 2020. Marine Renewable Energy plays a substantial role in this transition. However, while marine renewable energy will contribute to less GHG emissions, and thus enhance compliance with the Paris Agreement, there are concerns over potential impacts marine renewable energy installations may have on biodiversity. Such impacts include, among others, habitat loss, collision risks, noise and electromagnetic fields. This paper addresses these issues from the perspective of international environmental law, illustrating how potentially conflicting objectives (mitigating greenhouse gas emissions and preserving biodiversity) can be accommodated. This requires a discussion of broader concepts such as no harm and precautionary action as well as detailed rules extending from marine protected areas to the discussion of specific treaty issues, even public participation, including participation of indigenous peoples. The paper aims at illustrating the ability of international law to ensure not just an environmentally sound but a biodiversity-compatible transition towards marine renewable energy.

Abstract

Ocean law has developed greatly in the recent years as an area within maritime law and environmental law. The increased attention has been received mainly due to the sea- level rise, ocean acidification and changing ocean currents caused by climate change. The negative impacts of climate change affect a wide spectrum of law and policy and have direct and indirect implications on various aspects such as: international security, food security, shipping, fisheries, marine and coastal governance etc. According to the IPCC 2018 Report, ocean ecosystems are already experiencing large-scale changes and critical thresholds are expected to be reached at higher levels of global warming. The main aim of this article is to present how the ocean law and climate law respond to the regulatory challenges caused by climate change.

Abstract

The European Commission, continuing its efforts to contribute to the integrated governance of global oceans, promotes harmonization of respective regimes in its Member States. In its assessment of this process in 2019, the Commission stressed in its joint report to the European Parliament and the Council that healthy oceans can exist only if responsibility for this dynamic natural ecosystem is shared not only between states, but also between different kinds of cross-border operating actors and stakeholders. The dynamics of the marine environment shall be reflected in an elastic legal regime based not only on classic legal instruments like conventions and their national implementations, but also on different kinds of soft laws, standards and formal specifications created by representatives of these stakeholders. However, admitting that integrated governance is the long-term goal, the European Union also accepts solutions based on a sectoral approach, as long as they effectively fulfill the duty to protect the marine environment enabling use of the sea for mankind and economical use of the ocean. Such a comprehensive view on the ocean is also the background of the UNCLOS co-operation.
Integrated ocean governance and its mechanisms must then be created and developed by very diverse organisations and institutions, from classical international organizations, through to intergovernmental cooperations at different levels and private organizations. This article summarizes the achievements of practical cooperation of EU mechanisms of ocean governance with non-governmental private organisations, representing the de facto decentralised management of the world oceans. Extended analysis will reveal how climate change is becoming a major long-term driver of ecosystems, bringing together different actors in an integrated, ecosystem-based oceans management approach which highlights the interplay between environmental and economic conditions, and legal mechanisms and their reflections in documents prepared by private organisations.

Abstract

The aim of this work was to study the polyphenolic composition of Deschampsia antarctica È. Desv. plants grown at natural conditions on different locations on the Galindez Island, Argentine Islands, the maritime Antarctic. The plants were collected during the summer season of the 26th Ukrainian Antarctic Expedition (2020–2022). The extracts of 21 plants were obtained and the composition of the extracts was analyzed by means of high-performance liquid chromatography and matrix-assisted laser desorption/ionization mass spectrometry. The antioxidant properties of the extracts were characterized using the DPPH (2,2-diphenyl-1-picrylhydrazyl) test. The extracts were found to contain large amount of polyphenolic compounds, with flavonoids and phenolic acids, as well as their derivatives, being the most common classes of the phenols. Using the HPLC data the content of various phenols in the plants was systematic studied. It has been found that in all plants the most abundant phenols are flavonoids/flavonoid derivatives (on average about 75% of total mass of phenols). Among the flavonoids, luteolin derivatives predominate (86–94% of the total mass of flavonoids), and, among luteolin derivatives, the main compounds are orientin, orientin 2"- O-β-arabinopyranoside and isoswertiajaponin 2"- O-β-arabinopyranoside (67–83% of the total mass of luteolin derivatives). It has been also found that all the extracts possess the high activity in inhibition of DPPH radicals and that the antioxidant activity of the extracts correlates with total content of phenols in the samples. Thus, Deschampsia antarctica É. Desv. plants are a valuable source of natural phenolic antioxidants, and the most common antioxidants in the extracts are orientin, orientin 2"- O-β-arabinopyranoside and isoswertiajaponin 2"- O-β-arabinopyranoside.

Abstract

Ozone depletion at southern latitudes has recently increased the fluence of ultraviolet-B (UV-B) radiation striking the ground. This phenomenon has sparked much interest in unravelling the effects of this harmful radiation on living systems. UV-B radiation triggers several responses that affect plant physiology, morphology and biochemistry. In this study, the effect of supplemental UV-B radiation on DNA profile and chlorophyll a (CHl a) fluorescence characteristics were analyzed. An increase in the genetic variability of irradiated plants was observed in the Inter Sequence Simple Repeats products. The effect on photosynthesis was studied through fluorescence emissions. The obtained data showed that photochemical quenching (qP) decreased in irradiated plants. This effect may be attributed to a decrease in the number of open reaction centers of photosystem II (PSII) as suggested by the decreased values of minimal and maximal fluorescence. Likewise, non-photochemical quenching (NPQ) increased in both control and irradiated groups, but treated plants presented lower NPQ values than controls. The heat dissipation mechanism was also altered, probably due to a decrease in the yield of Fm´. According to these findings, UV-B radiation affects the CHl a fluorescence mechanisms and modifies DNA profile. Consequently, these changes influence the yield and growth of plants, which is an important consideration given the current climate change situation.
