Abstract: Tropical sardines (Family Clupeidae) are an important component of many marine fisheries in the Indo-West Pacific region. In Timor-Leste, a small, less-developed country within this region, ‘sardiña’ are some of the more commonly caught and consumed fish. Yet there is little published information from Timor-Leste about the species composition of these fisheries, nor their biology or ecology. We document the knowledge of Timorese fishers on nine locally distinguished sardine types that contribute to fisheries, and relate these to at least nine species: four species of ‘Flat-bodied Sardinellas’ ( Sardinella subg. Clupeonia spp.), one species of ‘Round-bodied Sardinella’ ( Sardinella subg. Sardinella lemuru ), two species of ‘Tropical Pilchards’ ( Amblygaster spp.) and a ‘Tropical Herring’ species ( Herklotsichthys quadrimaculatus ), all from the Clupeidae family and one Dussumieria species from the Dussumieriidae family. We record variations in local sardine names across the country and document aspects of fishers’ knowledge relevant to understanding and managing the fisheries, including local sardine species’ seasonality, habitat, movements, interannual variation, as well as post-harvest characteristics in relation to perishability. In general, local names relate more closely with groups of species than in idual species, although some names also distinguish fish size within species-groups. The local knowledge identified in this study has immediate application to inform fisheries monitoring and management, and to identify areas for future research. Notably, Timorese fishers recognize and make use of the strong association between some sardine species-groups and seasonally turbid river plumes. While further research is required to understand the underlying mechanisms of this association, this emphasizes the need to consider coastal fisheries and fisher livelihood impacts when assessing any plans or proposals that may alter river flow or water quality. Fishers also recognize migratory behavior of some sardine species, in particular the Flat bodied Sardinellas ( S. gibbosa and others) along the north-west coast of Timor-Leste and across the border into Indonesian West Timor. Such insights complicate and need to be accounted for in initiatives for co-management or community-based management of Timor-Leste’s coastal waters and their fisheries.

Abstract: A greater understanding of gendered roles in fisheries is necessary to value the often-hidden roles that women play in fisheries and households. We examine women’s contributions to household food and income using focus group discussions, market surveys, and landings data in six communities in Timor-Leste. Women were actively fishing more days per month than men. Gleaning was the most frequent activity and 100% of trips returned with catch for food and/or income. Mollusc and crab catches were common and exploitation appeared targeted on a dynamic reappraisal of changing food values and changing estimates of group needs. With as many as 80% of households in coastal areas involved in fishing, and at least 50% of women fishing, this highlights the current lack of women’s engagement as a critical gap in fisheries management approaches. The current androcentric dialogue limits social-ecological understanding of these systems and the potential for their effective stewardship.

Abstract: de Graaf, G. J., Grainger, R. J. R., Westlund, L., Willmann, R., Mills, D., Kelleher, K., and Koranteng, K. 2011. The status of routine fishery data collection in Southeast Asia, central America, the South Pacific, and West Africa, with special reference to small-scale fisheries. – ICES Journal of Marine Science, 68: 1743–1750. The Food and Agriculture Organization (FAO) strategy for improving information on the status and trends of capture fisheries (FAO Strategy STF) was endorsed by Member States and the UN General Assembly in 2003. Its overall objective is to provide a framework, strategy, and plan to improve knowledge and understanding of the status and trends of fisheries as a basis for policy-making and management, towards conservation and sustainable use of resources within ecosystems. The FAO supports the implementation of FAO Strategy STF in developing countries through a project known as FAO FishCode–STF, and an initiative funded by the World Bank entitled the “BigNumbers project”. The BigNumbers project underscored the importance of small-scale fisheries and revealed that catches by and employment in this sector tend to be underreported. An inventory of data collection systems made under the FAO FishCode–STF project showed that small-scale fisheries are not well covered. Their dispersed nature, the weak institutional capacity in many developing countries, and the traditional methods used make routine data collection cumbersome. Innovative s ling strategies are required. The main priority is a s le frame for small-scale fisheries. Sustainable strategies are most likely to be found outside the sector through population and agricultural household censuses and inside the sector through the direct involvement of fishers.

Abstract: Leadership is heralded as being critical to addressing the “crisis of governance” facing the Earth's natural systems. While political, economic, and corporate discourses of leadership have been widely and critically interrogated, narratives of environmental leadership remain relatively neglected in the academic literature. The aims of this paper are twofold. First, to highlight the centrality and importance of environmental science's construction and mobilization of leadership discourse. Second, to offer a critical analysis of environmental sciences' deployment of leadership theory and constructs. The authors build on a review of leadership research in environmental science that reveals how leadership is conceptualized and analyzed in this field of study. It is argued that environmental leadership research reflects rather narrow framings of leadership. An analytical typology proposed by Keith Grint is employed to demonstrate how any singular framing of environmental leadership as person, position, process, result, or purpose is problematic and needs to be supplanted by a pluralistic view. The paper concludes by highlighting key areas for improvement in environmental leadership research, with emphasis on how a political ecology of environmental crisis narratives contributes to a more critical body of research on leadership in environmental science.

Abstract: Food system is a powerful concept for understanding and responding to nutrition and sustainability challenges. Food systems integrate social, economic, environmental and health aspects of food production through to consumption. Aquatic foods are an essential part of food systems providing an accessible source of nutrition for millions of people. Yet, it is unclear to what degree research across erse disciplines concerning aquatic foods has engaged food systems, and the value this concept has added. We conducted a systematic review of fisheries, aquaculture and aquatic food literature (2017–2019) to determine the following: the characteristics of this research the food systems components and interrelations with which research engaged and the insights generated on nutrition, justice, sustainability and climate change. Sixty five of the 88 reviewed articles focussed on production and supply chains, with 23 considering human nutrition. Only 13% of studies examined low‐ and middle‐income countries that are most vulnerable to undernutrition. One third of articles looked beyond finfish to other aquatic foods, which illuminated values of local knowledge systems and erse foods for nutrition. When aggregated, reviewed articles examined the full range of food system drivers—biophysical and environmental (34%), demographic (24%) and socio‐cultural (27%)—but rarely examined interactions between drivers. Future research that examines a ersity of species in diets, system‐wide flows of nutrients, trade‐offs amongst objectives, and the nutritional needs of vulnerable social groups would be nudging closer to the ambitions of the food systems concept, which is necessary to address the global challenges of equity, nutrition and sustainability.

Abstract: The novel coronavirus is predicted to have dire implications on global food systems including fisheries value chains due to restrictions imposed on human movements in many countries. In Ghana, food production, both agriculture and fisheries, is exempted from restrictions as an essential service. The enforcement of COVID-19 prevention protocols, particularly social distancing, has been widely reported in Ghana’s agricultural markets whereas casual observations and media reports on fish landing sites suggest no such enforcements are in place. This study aimed to provide sound scientific evidence as a basis for informed policy direction and intervention for the artisanal fishing sector in these challenging times. We employed an unmanned aerial vehicle in assessing the risk of artisanal fishers to the pandemic using physical distancing as a proxy. From analysis of cumulative distribution function (G-function) of the nearest-neighbour distances, this study underscored crowding at all surveyed fish landing beaches, and identified potential “hotspots” for disease transmission. Aerial measurements taken at times of peak landing beach activity indicated that the highest proportion of people, representing 56%, 48%, 39% and 78% in Elmina, Winneba, Apam and Mumford respectively, were located at distances of less than one metre from their nearest neighbour. Risk of crowding was independent of the population at the landing beaches, suggesting that all categories of fish landing sites along the coast would require equal urgency and measured attention towards preventing and mitigating the spread of the disease.

Abstract: Motivated by growing concern as to the many threats that islands face, subsequent calls for more extensive island nature conservation and recent discussion in the conservation literature about the potential for wellbeing as a useful approach to understanding how conservation affects people's lives, this paper reviews the literature in order to explore how islands and wellbeing relate and how conservation might impact that relationship. We apply a three-dimensional concept of social wellbeing to structure the discussion and illustrate the importance of understanding island–wellbeing interactions in the context of material, relational and subjective dimensions, using ex les from the literature. We posit that islands and their shared characteristics of ‘islandness’ provide a useful setting in which to apply social wellbeing as a generalizable framework, which is particularly adept at illuminating the relevance of social relationships and subjective perceptions in island life – aspects that are often marginalized in more economically focused conservation impact assessments. The paper then explores in more depth the influences of island nature conservation on social wellbeing and sustainability outcomes using two case studies from the global north (UK islands) and global south (the Solomon Islands). We conclude that conservation approaches that engage with all three dimensions of wellbeing seem to be associated with success.

Abstract: The small-scale fisheries sector in many Pacific islands is facing increasing challenges in relation to resource availability, economic opportunity, and demographic and social pressure. In particular, intensifying cash-oriented livelihood strategies can exacerbate existing vulnerabilities and threaten food security and resource conservation. In this paper the authors develop a bio-economic model and a quantitative measure of resilience in order to explore the interaction between socio-economic and ecological dynamics, and to analyze the potential role that cooperation and collective arrangements can play in this interaction to maintain the viability of the system. Based on the case of the system known as wantok typically found in the Solomon Islands, numerical ex les are used to explore the potential gain that cooperation between fishers can bring in terms of subsistence, profitability and ecological performances, as well as the resilience of the whole system to shocks.

Abstract: Livelihood ersification is increasingly central to policy advice and investments in rural development and fisheries management. For small‐scale fishing communities in low‐ to middle‐income countries, more erse livelihoods are generally hypothesized to reduce fishing pressure and vulnerabilities to external shocks and adverse trends while enabling people to construct routes out of poverty. Yet, evidence of impacts from livelihood ersification in small‐scale fisheries remains sparse. Our examination of the peer‐reviewed literature found substantial differences in how livelihood ersification is pursued, and in the realized outcomes from the process of ersification. Studies describing ersified livelihoods were almost as likely to report that livelihoods were not improved or that outcomes were mixed (54% combined) as they were to report improved livelihood outcomes (45%). Furthermore, one of the main theoretical drivers behind the support for ersified livelihoods—ecological conservation benefits—was unexplored in over 70% of studies. Of the minority of studies that did explore ecological outcomes, most reported that ecological conditions had not improved. These findings indicate conceptual ambiguity around livelihood ersification and a lack of empirical evidence supporting its theoretical underpinnings. There remain important questions about the impacts of ersification on multidimensional poverty and ecological conservation. Future research on and investment in ersification should be both more deliberate of what ersification means and more rigorous in the evaluation of its impacts.
