Full textAbstract:
International air transport is one of the fast-growing sources of CO2 emissions. However, it has always been omitted from the international emission mitigation pledges. The delayed mitigation process in this area may slow down the process of global CO2 emission control. In this article, we evaluated the potential to realize the emission mitigation targets in air transport through biofuel and estimated the corresponding cost. The emission from international air transport of Palau and Seychelles was taken as the example. Then, the emission caused by each airline to these two islands was calculated by the distance-based method, with information of the travelers’ arrival data, fuel consumption of different aircraft types, routes, and aircraft seat data. Future scenarios with and without commitment to CO2 mitigation targets were predicted to evaluate the emission difference. Then, we estimated the amount of biofuel required to fill the emission gap, and the corresponding cost based on the future biofuel price prediction. The results show that distance is the determining factor of international air transport emission per capita. The component of origin can decrease the aggregated emission per capita to small island destinations by 0.5–2%. The accumulated emission gaps are 3.15 Mt and 9 Mt for Palau and Seychelles, which indicates that 7.64 and 19.34 Mb of biofuel are needed for emission mitigation, respectively. The corresponding costs are $27–163 million and $72–424 million per year.

Full textAbstract:
Abstract The genesis of mixed layer temperature anomalies across the Indian Ocean are analyzed in terms of the underlying heat budget components. Observational data, for which a seasonal budget can be computed, and a climate model output, which provides improved spatial and temporal coverage for longer time scales, are examined. The seasonal climatology of the model heat budget is broadly consistent with the observational reconstruction, thus providing certain confidence in extending the model analysis to interannual time scales. To identify the dominant heat budget components, covariance analysis is applied based on the heat budget equation. In addition, the role of the heat budget terms on the generation and decay of temperature anomalies is revealed via a novel temperature variance budget approach. The seasonal evolution of the mixed layer temperature is found to be largely controlled by air–sea heat fluxes, except in the tropics where advection and entrainment are important. A distinct shift in the importance and role of certain heat budget components is shown to be apparent in moving from seasonal to interannual time scales. On these longer time scales, advection gains importance in generating and sustaining anomalies over extensive regions, including the trade wind and midlatitude wind regimes. On the other hand, air–sea heat fluxes tend to drive the evolution of thermal anomalies over subtropical regions including off northwestern Australia. In the tropics, however, they limit the growth of anomalies. Entrainment plays a role in the generation and maintenance of interannual anomalies over localized regions, particularly off Sumatra and over the Seychelles–Chagos Thermocline Ridge. It is further shown that the spatial distribution of the role and importance of these terms is related to oceanographic features of the Indian Ocean. Mixed layer depth effects and the influence of model biases are discussed.

Full textAbstract:
Abstract In this study, the Indian Ocean upper-ocean variability associated with the subtropical Indian Ocean dipole (SIOD) is investigated. We find that the SIOD is associated with a prominent southwest–northeast sea level anomaly (SLA) dipole over the western-central south Indian Ocean, with the north pole located in the Seychelles–Chagos thermocline ridge (SCTR) and the south pole at southeast of Madagascar, which is different from the distribution of the sea surface temperature anomaly (SSTA). While the thermocline depth and upper-ocean heat content anomalies mirror SLAs, the air–sea CO2 flux anomalies associated with SIOD are controlled by SSTA. In the SCTR region, the westward propagation of oceanic Rossby waves generated by anomalous winds over the eastern tropical Indian Ocean is the major cause for the SLAs, with cyclonic wind causing negative SLAs during positive SIOD (pSIOD). Local wind forcing is the primary driver for the SLAs southeast of Madagascar, with anticyclonic winds causing positive SLAs. Since the SIOD is correlated with ENSO, the relative roles of the SIOD and ENSO are examined. We find that while ENSO can induce significant SLAs in the SCTR region through an atmospheric bridge, it has negligible impact on the SLA to the southeast of Madagascar. By contrast, the SIOD with ENSO influence removed is associated with an opposite SLA in the SCTR and southeast of Madagascar, corresponding to the SLA dipole identified above. A new subtropical dipole mode index (SDMI) is proposed, which is uncorrelated with ENSO and thus better represents the pure SIOD effect.

Full textAbstract:
The article describes and analyzes the activities of the Indian Navy during the COVID-19 pandemic. The author looks at the experience of the Indian Navy at the beginning of the pandemic, noting that it mainly consisted of helping the states of the Indian Ocean region affected by hurricanes and monsoons, and evacuating Indian citizens and residents of neighboring countries from areas of hostilities. At the same time, the Indian Navy did not have specialized floating hospitals. The author analyzes the situation in which India found itself at the beginning of the pandemic: a gradual slowdown in GDP growth questioned the further expansion of the Navy, and the outbreak of conflict with China further emphasized the importance of the Air Force and the Army. In these conditions, the Indian Navy was forced to prove its value for the Indian external and domestic policy. The author then describes how the Indian Navy fought COVID-19, concluding that Indian sailors were able to prevent the pandemic from spreading to naval bases and ships. The Navy fully retained its combat capability and was able to take part in two large-scale operations: the “Samudra Setu”and “Sagar” missions. During the former, several thousand people were evacuated from Iran, Sri Lanka and the Maldives, the latter involved providing medical assistance to the population of the Maldives, Seychelles, Comoros, Madagascar and Mauritius affected by the pandemic. The author notes the high level of organization of both missions, which made it possible to avoid pandemic spreading among the ship crews. He argues that the conduct of Operation “Sagar” allowed India to increase its influence in the Indian Ocean region amid the pandemic and demonstrate its role as a security provider countering unconventional threats. The author then describes the joint exercises carried out by the Indian Navy during the pandemic and notes their significant political role. In conclusion, he analyzes the experience of the Indian Navy using soft power and proposes an original concept of “floating soft power” based on the constant presence of hospital ships in remote regions. In his opinion, this format of presence could also be suitable for projecting Russian interests in the South Pacific.

Full textAbstract:
Persistent organic pollutants (POPs) are organic (carbon-based) compounds that include synthesized substances (pesticides and polychlorinated biphenyls [PCBs]) and other by-product substances generated as a result of human and natural activity (dioxins and furans). Extensive scientific studies have shown that POPs are some of the most dangerous pollutants released into the environment by humans. Great efforts have been made since the early 1960s to enhance chemical management and safety issues. Various conventions have been adopted for this purpose: the Stockholm Convention (SC) is one of the well-known meetings in this context. The SC on POPs (May 2001) focuses on reducing and eliminating releases of 12 POPs coined the ‘Dirty Dozen’ by the United Nations Environment Program (UNEP). Persistence of such chemicals in soils, air, and water, together with natural processes such as evaporation to the atmosphere and washout by rain and flood, give rise to their ubiquitous distribution in the environment and eventual penetration into food chains and bio-accumulation in humans. Public concern about contamination by POPs increased recently because several of these compounds are identified as hormone disruptors, which can alter normal function of endocrine and reproductive systems in humans and wildlife. African countries are using pesticides, such as dichlorodiphenyltrichloroethane (DDT), lindane, toxaphene, endrin, dieldrin, heptachlor, since more than 50 years for combating agricultural pests and controlling disease vectors, especially malaria. The way in which pesticides are used in Africa caused serious environmental and health problems much more than elsewhere. These problems are represented by accumulation of organochlorine pesticide (OCP) residues in different environmental samples and hosting of at least 50,000 tons of obsolete pesticides, as well as tens of thousands of tons of contaminated soil. Within the framework of the Africa Stockpiles Program (ASP), huge quantities of pesticidal POPs have been completely or partially destroyed in a number of African countries (e.g. Egypt, Namibia, Niger, Senegal, Seychelles, South Africa, Sudan, Tanzania, Uganda, Zambia). At regional level (i.e. African Countries), a strategic plan for monitoring and getting rid of POPs in the continent should be set up and implemented through coordination between all governments. Among issues of top priorities are to find alternative non-combustion technologies for disposing obsolete pesticides, and to use alternative control measures for mosquitoes’ management and other vector-borne diseases.

Full textAbstract:
Piracy off the coast of Somalia has elicited a growing body of interdisciplinary research. Much of this research focuses on identifying the root causes of piracy, analyzing onshore and offshore responses, or evaluating various rule-of-law approaches; no study has yet to examine how Somali piracy has impacted prisons. Drawing upon ethnographic research, this article explores how UNODC counter piracy funding is reshaping the carceral spaces of East Africa. I examine how the need to secure and develop Somali piracy prisoners in regional prisons has created a bodies-for-aid penal market in East Africa. Large aid packages are awarded to prisons that agree to accept suspected Somali pirates and ensure the support, maintenance, and enhancement of the lives of Somali piracy prisoners. I theorize a new form of penal aid— biopolitical penal aid—linking prison development funding to the containment of specific prisoner populations. Using the Montagne Posée Prison in the Seychelles as a case study, I explore how biopolitical penal aid is reshaping prison spaces and practices to tease out underlying tensions between international and regional security projects, how these projects are negotiated and appropriated at different scales, and how they are being experienced by staff and Somali piracy prisoners.

Full textAbstract:
In studying organisational change in Air Seychelles, the context, content and process of change together with the interconnections of the airline and the tourism industry in Seychelles through time is explored. The literature review shows that the substantive issues of interest to this study, contextualism as a theory of methods in management research, requires a case based research in particular with regards to the following gaps in the literature: the integration of inner and outer perspectives on sustaining competitive advantage, and conceptual insights on how strategy links firms and their environment. The study adopted a contextual and processual framework to build a theoretical perspective of competitive advantage.
The study contributes to the field of strategic management and tourism development in Seychelles in the following ways: firstly, the development of a contextual and processual framework to explain the transformation of firms over time; secondly, the development of an understanding of the historical context of the tourism industry and its interactions with other sectors of the Seychelles economy; thirdly, developing an understanding of how Air Seychelles developed its resources and capabilities to sustain competitive advantage; fourthly, linking change processes and action to performance and in a sense developing an understanding on strategy implementation of strategic management practice in Air Seychelles.
The study sheds some light on strategy formation and implementation at the firm level, and the dynamics between the firm and the industry. The findings suggest that firms respond opportunistically to external discontinuities in a dynamic environment - the entrepreneurial leadership of a firm prepares and support managers to operate under conditions of great uncertainty and ambiguity and allows them to behave opportunistically.<br>Graduate School of Business Leadership<br>DBL<br>Thesis (D.
