Planetary health literacy: A conceptual model

Education for planetary health could be one of the key levers of the much-needed civilizational turn toward a sustainable and healthy future. Education goes beyond information provision and passing on of knowledge and includes competencies to transfer knowledge from one decision situation to another. There are a range of different literacy concepts from various research perspectives that aim to improve such competencies. While many contain aspects highly relevant for planetary health, there is still no comprehensive and integrative planetary health approach. To fill this research gap, we present a conceptual model of planetary health literacy. By zooming into the model, further details on the necessary core competencies of accessing, understanding, appraising, and applying information in order to make judgements and take decisions regarding planetary health can be found. Zooming out of the model allows a holistic planetary health perspective and shows the potential and opportunities of planetary health literacy for the health of humans and ecosystems. Planetary health literacy encompasses both a life-course and a transgenerational approach, at the individual, societal, and global level. Future educational programs focusing on planetary health could integrate the conceptual model to increase planetary health literacy of individuals, including relevant health literacy agents, and of societies.

Institutions and institutional changes: aquatic food production in Central Luzon, Philippines

Aquaculture is the most rapidly growing food production sector globally. In certain coastal social-ecological systems, this has resulted in significant changes and sustainability challenges. In particular, coastal environments which used to support only capture fisheries are becoming sites for brackish water aquaculture production; this impacts the sustainability of aquatic food production. Sustainability challenges associated with aquaculture expansion and intensification necessitate a contextually rooted understanding of institutions and institutional changes which can be used as an informed basis for leveraging institutions to achieve desirable sustainability outcomes in the aquatic food sector. This research used a qualitative empirical case study involving in-depth interviews, participant observation, and analysis of institutional documents in the region of Central Luzon, Philippines. It applied the inter-institutional systems concept which considers multiple institutions with distinct but linked purposes and functions in the societal spheres of state, market, and civil society. The study found that aquaculture emerged as an important livelihood because of rice farmers' need to adapt to saltwater intrusion into what were formerly rice farms. It grew into an industry due to developments in the availability and accessibility of inputs such as fingerlings and feeds. This process was also driven by the high demand and high profitability of fish farming at the time. Regulatory institutions have not adequately adapted to protect the environment. Market institutions adapted but the changes mostly benefited consignacions (middlemen) and large-scale players. However, organised groups of collaborating smallholder fishers and fish farmers are helping to address the disadvantages they face.

The 'wickedness' of governing land subsidence: Policy perspectives from urban Southeast Asia

Drawing on Jakarta, Metro Manila and Singapore as case studies, we explore the paradox of slow political action in addressing subsiding land, particularly along high-density urban coastlines with empirical insights from coastal geography, geodesy analysis, geology, and urban planning. In framing land subsidence as a classic 'wicked' policy problem, and also as a hybrid geological and anthropogenic phenomenon that is unevenly experienced across urban contexts, the paper uses a three-step analysis. First, satellite-derived InSAR maps are integrated with Sentinel-1A data in order to reveal the socio-temporal variability of subsidence rates which in turn pose challenges in uniformly applying regulatory action. Second, a multi-sectoral mapping of diverse policies and practices spanning urban water supply, groundwater extraction, land use zoning, building codes, tenurial security, and land reclamation reveal the extent to which the broader coastal governance landscape remains fragmented and incongruous, particularly in arresting a multi-dimensional phenomenon such as subsidence. Finally, in reference to distinct coastal identities of each city-the 'Sinking Capital' (Jakarta), 'Fortress Singapore', and the 'Disaster Capital' (Manila) the paper illustrates how land subsidence is portrayed across the three metropolises in markedly similar ways: as a reversible, quasi-natural, and/or a highly individualized problem.

Aquaculture-capture fisheries nexus under Covid-19: impacts, diversity, and social-ecological resilience

The Covid-19 pandemic is a global shock that is significantly affecting coastal social-ecological systems (SES) in different parts of the world. Its widespread impacts have unravelled vulnerabilities in many aspects of society, including food systems. Our study investigated the impacts of a lockdown associated with the pandemic in the province of Bulacan, in the region of Central Luzon, Philippines, where aquaculture and capture fisheries are important and interconnected sectors. In particular, we focused on impacts related to production and market. We considered people's coping strategies and the factors that enabled such strategies. Our investigation adopted a case study approach and drew on qualitative data analysed through thematic analysis. The findings revealed differentiated mechanisms through which aquaculture and capture fisheries production were impacted. Both were strongly affected by market disruptions but through slightly different ways. In effect, the lockdown provided the impetus for the uptake and spreading of practices that were previously peripheral, particularly in relation to market exchanges. The study also identified a variety of coping strategies, as well as the importance of social support in the form of food aid, financial assistance, and institutional livelihood assistance. Finally, it discusses the importance of diversity in food sources, the role of local food systems, and governance implications for foregrounding social-ecological resilience in short-term response and long-term recovery.

Tropical marine sciences: Knowledge production in a web of path dependencies

Scientific agenda setting is critical at all levels of research, but can be strongly influenced by structural path dependencies of the science system itself. In this article we examine how knowledge production is shaped by interconnected path dependencies using the field of tropical marine sciences as a global case study. We use scientometric analysis methods on an original data set of 1328 peer-reviewed journal publications to examine publication trends including a co-authorship network analysis, links between author origin and research locations as well as a quantitative analysis of terminology use over space (i.e., region) and time. Scientometric findings are analytically discussed through a conceptual framework premised on theories of path dependency. Findings and critical analysis highlight how tropical marine science provides a prominent global example of how North American, European and Australian science programs predominantly shape knowledge production of the global science system, generating critical reflection on the path dependencies these create on current and likely future knowledge production and science agendas. Similar dependencies face other fields of science, and thus this study provides broadly relevant quantitative observational empirical findings supplemented with a critical social science analysis of how a transcultural Science and Technology Studies lens is useful for unpacking the webs of path dependencies driving, inhibiting and/ or shaping global knowledge production, placing meaning and context over observed empirical trends.
