Abstract: To build capacity for addressing complex sustainable development challenges, governments, development agencies, and non-governmental organizations are making substantial investments in governance networks. Yet, enthusiasm for establishing governance networks is not always matched by empirical evidence on their effectiveness. This gap challenges these groups to know whether investing in governance networks is worth their time and effort a weighing-up that is particularly critical in contexts of limited resources. Through a qualitative case study in Solomon Islands, we evaluate the extent to which a governance network, called the Malaita Provincial Partners for Development, contributed to four dimensions of collaborative governance capacity: in idual, relational, organizational, and institutional. We find that the network made moderate contributions to in idual, relational and organizational capacity, while institutional capacity remained low despite the presence of the network. Based on these findings, we argue that governance networks are not a panacea. Continued efforts are needed to establish when, how, and in what contexts collaborative networks are effective for building collaborative capacity for sustainable development.

Abstract: Big-bellied seahorses, Hippoc us abdominalis (Chordata: Syngnathidae), feed predominantly on swarming mysids in southern Tasmania. We tested the possibility that kairomones mediate this predator rey interaction. ‘Fish water’ was prepared by holding one seahorse in 4 l of seawater for 1 h and using this water within 1 h to test for presence of kairomones. One ml of this water pipetted into a tank containing five mysids, Paramesopodopsis rufa (Arthropoda: Mysidacea), induced a significantly increased number of tailflips (mysid escape response) compared with control seawater. The same effect was seen whether seahorses were fed or starved immediately before the experiment. This effect was not seen when realistic concentrations of excretory products, either ammonium hydroxide or urea, were used instead of fish water. When seahorses were kept in visual contact with mysid prey, but unable to capture them, subsequent testing of the ‘fish water’ in the same way as above did not produce a significant increase of tailflipping in mysids. Thus it appears that, when attacking, seahorses can suppress release of kairomones in order to remain chemically inconspicuous to their prey. This is the first demonstration of this phenomenon. When mysids in a cohesive swarm (65 or 100 in iduals) were exposed to ‘fish water’, no significant anti-predator response i.e. decrease in swarm volume, could be detected. We interpret these results to indicate the greater vulnerability of mysids when not in social groupings (swarm or school) and the higher likelihood of an energetic response (particularly tailflipping) to a threat.

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 challenge to manage coastal resources within Asia-Pacific's Coral Triangle has gained global attention. Co-management is promoted as a key strategy to address this challenge. Contemporary community-based co-management often leads to ‘hybridization’ between local (customary) practices, and science-based management and conservation. However, the form of this hybrid has rarely been critically analysed. This paper presents ex les of co-management practices in eastern Indonesia and Solomon Islands, focusing in particular on area closures. In contrast to the temporary closures used before the influx of sustainability discourses, contemporary closures are periodically-harvested but predominantly closed, reflecting attempts to reduce fishing effort and enhance ecological sustainability. When areas are opened, harvests are relatively short and largely triggered by the social and economic needs of particular in iduals or whole communities. In all cases, engagement with environmental management interventions has led to more formalized access and use arrangements. The harvesting and management practices observed are influenced by these relatively recent interventions designed to promote sustainability, but also by religious institutions, increasing resource demand, and modernization. This study unpacks some of the contemporary influences, particularly environmental sustainability initiatives, on local management practices, and provides insights for co-management in practice.

Abstract: Injustices are prevalent in food systems, where the accumulation of vast wealth is possible for a few, yet one in ten people remain hungry. Here, for 194 countries we combine aquatic food production, distribution and consumption data with corresponding national policy documents and, drawing on theories of social justice, explore whether barriers to participation explain unequal distributions of benefits. Using Bayesian models, we find economic and political barriers are associated with lower wealth-based benefits countries produce and consume less when wealth, formal education and voice and accountability are lacking. In contrast, social barriers are associated with lower welfare-based benefits aquatic foods are less affordable where gender inequality is greater. Our analyses of policy documents reveal a frequent failure to address political and gender-based barriers. However, policies linked to more just food system outcomes centre principles of human rights, specify inclusive decision-making processes and identify and challenge drivers of injustice.

Abstract: Nearly a billion people depend on tropical seascapes. The need to ensure sustainable use of these vital areas is recognised, as one of 17 policy commitments made by world leaders, in Sustainable Development Goal (SDG) 14 (‘Life below Water’) of the United Nations. SDG 14 seeks to secure marine sustainability by 2030. In a time of increasing social-ecological unpredictability and risk, scientists and policymakers working towards SDG 14 in the Asia–Pacific region need to know: (1) How are seascapes changing? (2) What can global society do about these changes? and (3) How can science and society together achieve sustainable seascape futures? Through a horizon scan, we identified nine emerging research priorities that clarify potential research contributions to marine sustainability in locations with high coral reef abundance. They include research on seascape geological and biological evolution and adaptation elucidating drivers and mechanisms of change understanding how seascape functions and services are produced, and how people depend on them costs, benefits, and trade-offs to people in changing seascapes improving seascape technologies and practices learning to govern and manage seascapes for all sustainable use, justice, and human well-being bridging communities and epistemologies for innovative, equitable, and scale-crossing solutions and informing resilient seascape futures through modelling and synthesis. Researchers can contribute to the sustainability of tropical seascapes by co-developing transdisciplinary understandings of people and ecosystems, emphasising the importance of equity and justice, and improving knowledge of key cross-scale and cross-level processes, feedbacks, and thresholds.

Abstract: Poverty and food insecurity persist in sub-Saharan Africa. We conducted a secondary analysis of nationally representative data from three sub-Saharan Africa countries (Malawi, Tanzania, and Uganda) to investigate how both proximity to and engagement with small-scale fisheries are associated with household poverty and food insecurity. Results from the analysis suggest that households engaged in small-scale fisheries were 9 percentage points less likely to be poor than households engaged only in agriculture. Households living in proximity to small-scale fisheries (average distance 2.7 km) were 12.6 percentage points more likely to achieve adequate food security and were 15 percentage points less likely to be income poor, compared to the most distant households. Households distant from fishing grounds ( km) were 1.5 times more likely to consume dried fish compared to households living close. Conserving the flow of benefits from small-scale fisheries is important for meeting the Sustainable Development Goals in the region.

Abstract: Hilsa shad (Tenualosa ilisha) , is a biologically, nutritionally, economically, socially and culturally important species in the Bay of Bengal and Persian Gulf regions, but Bangladesh enjoys the major share wherein it contributes about 517,000 tons/year. However, this important fishery declined in the late 1990’s that led the Government to formulate the Hilsa Fishery Management Action Plan (HFMAP) and started its implementation from 2005. Since then, hilsa production increased @5%/year till 2015. To improve the annual incremental production further, Department of Fisheries (DoF) and WorldFish have jointly been implementing “Enhanced Coastal Fisheries in Bangladesh (ECOFISH-Bangladesh)”, a USAID supported project (2014-2019). The project supports the DoF and local communities to establish a science-based “adaptive co-management” that focuses on the brood hilsa protection, juvenile conservation, illegal gears control, and overall ecosystem resilience involving all stakeholders. As a synergistic impact of all the initiatives taken and the proactive supports of the law enforcing agencies, the declined hilsa fishery from both inland and marine habitats revived @ 11% annual incremental total hilsa catch. The increased hilsa production and average size (from 510 g to 915 g) resulted in increased household income of fishers by 52%. The interventions additionally improved catfish abundance and other fish bio ersity.

Abstract: Improving livelihoods and livelihood opportunities is a popular thrust of development investments. Gender and other forms of social differentiation influence in idual agency to access, participate in, and benefit from existing, new, or improved livelihood opportunities. Recent research illustrates that many initiatives intended to improve livelihoods still proceed as “gender blind,” failing to account for the norms and relations that will influence how women and men experience opportunities and outcomes. To examine gender in livelihoods, we employed empirical case studies in three coastal communities in Solomon Islands a small island developing state where livelihoods are predominantly based on fisheries and agriculture. Using the GENNOVATE methodology (a series of focus groups) we investigated how gender norms and relations influence agency (i.e., the availability of choice and capacity to exercise choice). We find that men are able to pursue a broader range of livelihood activities than women who tend to be constrained by in idual perceptions of risk and socially prescribed physical mobility restraints. We find the livelihood portfolios of women and men are more erse than in the past. However, livelihood ersity may limit women’s more immediate freedoms to exercise agency because they are simultaneously experiencing intensified time and labor demands. Our findings challenge the broad proposition that livelihood ersification will lead to improvements for agency and overall wellbeing. In community-level decision-making, men’s capacity to exercise choice was perceived to be greater in relation to livelihoods, as well as strategic life decisions more broadly. By contrast, capacity to exercise choice within households involved spousal negotiation, and consensus was considered more important than male or female dominance in decision-making. The prevailing global insight is that livelihood initiatives are more likely to bring about sustained and equitable outcomes if they are designed based on understandings of the distinct ways women and men participate in and experience livelihoods. Our study provides insights to make these improvements in a Solomon Islands setting. We suggest that better accounting for these gendered differences not only improves livelihood outcomes but also presents opportunity to catalyze the re-negotiation of gender norms and relations thereby promoting greater in idual agency.

Abstract: Effective actions for the fishery and aquaculture sectors to contribute toward improving nutrition rely on an understanding of the factors influencing fish intake, particularly amongst vulnerable populations. This scoping review synthesises evidence from 33 studies in the African Great Lakes Region to examine the influence of food environments on fish acquisition and consumption. We identified only two studies that explicitly applied a food environment framework and none that linked policy conditions with the contribution of fish to diets. Economic access to fish was represented in the largest number of included studies (21 studies), followed by preferences, acceptability and desirability of fish (17 studies) and availability and physical access (14 studies). Positive perceptions of taste and low cost, relative to other animal-source foods, were drivers of fish purchases in many settings however, limited physical and economic access were frequently identified as preventing optimal intake. In lakeside communities, fish were increasingly directed toward external markets which reduced the availability and affordability of fish for local households. Few studies considered intra-household variations in fish access according to age, gender or physiological status, which represents an important knowledge gap. There is also scope for future research on seasonal influences on fish access and the design and rigorous evaluation of programmes and policies that address one or more constraints of availability, cost, convenience and preferences.
