Raw attitudes relate to the food cultures, eating habits, and behaviours of people in relation to the consumption of raw, partially cooked, and fermented freshwater fish dishes, which puts people at risk of Ophistochis viverrini and other parasitic infections. The chapter reviews raw attitudes within the countries and across the borders of the greater Mekong region, particularly northeast Thailand, Lao PDR, Vietnam, and Cambodia. Rather than treat each nation-state as an isolated epidemiological box, the chapter explores transborder complexity in relation to multiple anthropogenic transformations to the landscapes of the region and developmental impacts upon ecosystems and life cycles. Economic projects such as multiple hydropower dams, irrigation schemes, water-diversions, roads, and aquaculture ponds have significant impacts on FTZ life-cycle dynamics. In addition, many ecological changes are transboundary ones, and there are added complications relating human mobility, altered agrarian landscapes, and significant numbers of migrant workers. The chapter also examines public health programmes and educational interventions which are altering perceptions of O. viverrini and cholangiocarcinoma over time. A key argument is the need for transdisciplinary scientific and social science strategies alongside multi-pronged health interventions, such as ‘the CASCAP model’. There exist many unknowns and gaps relating to widespread anthropogenic modifications upon life cycles, upon lifestyles, livelihoods, and human behaviours, which require research projects that span socio-economic, ecological, geographical, and public health dynamics of disease.

COVID-19 has become a global public health pandemic which requires scientific, technical, public policy and health system responses at multi-scales. COVID-19 is also a pandemic that is impacting socio-economic and political systems in profound ways. This paper briefly outlines why and how pandemics may expose uneven socio-economic geographies of vulnerability and risk, and also be thought of in relation to environmental and non-human challenges to our geopolitical map of territorial nation-states and sovereignties. In relation to Southeast Asia we argue that preexisting and ongoing political-economy linkages are shaping key responses to COVID-19. In particular, we consider the geopolitical and geoeconomic reasoning of Cambodia and Myanmar, and their relations with China. We reflect on the factors that shape their national responses in response to the pandemic, characterized by certain silences and erasures to their local geographies.

This paper focuses on the ‘the unseen transboundary commons’ of residues, nutrients and mobile matter associated with the annual flood pulse that support Cambodia's inland fisheries. We develop the idea of biophysical geopolitics concentrating on political‐socio‐natures rather than the purely biophysical. In the context of multiple mega‐projects in the Basin, we argue the flood pulse has become increasingly compromised, which is an urgent socio‐ecological security issue facing the Mekong region. Scores of livelihoods are dependent on the hydrological flood pulse via the reproduction of the inland fisheries, and a diversity of wetlands resources. Our paper builds on cross‐comparative research focusing on a geo‐strategic mouth of the Tonle Sap (Chhnok Tru) and a transborder area along the Mekong main‐stream (Stung Treng, Cambodia – Champasak, Laos area). By viewing biophysical matter as becoming trans‐border geopolitical matter, we wish to emphasise the critical socio‐ecological character of the hydrological flood pulse, and the urgency of cumulative spatial and temporal changes affecting diverse wetlands communities. Loss of wild capture fisheries and the more unpredictable flows of the Mekong are signs of an emergent and dangerous era of increasing environmental insecurity.

Hydropower development on the mainstream of the Mekong River in the Lower Mekong Basin (lmb) has become one of the most pressing issues on the development agenda, being touted as the way forward in solving energy, development and sustainability needs in the region. Despite dominant and compelling arguments in favour of such development, a growing anti-dam lobby has taken to arguing that hydropower development will threaten the economic, social, environmental and food security of some 62 million people living in the lmb. The anti-dam lobby comprises a heterogeneous assemblage of actors, agencies and networks, working to provide critical and alternative geographical (re)imaginations of the lmb. This paper explores these multiple perspectives afforded by the anti-dam lobby through the lens of knowledge production. The anti-dam lobby, it will be seen, engages in a politics of legitimacy and re-scaling with the pro-hydropower lobby, played out through varying strategies, while highlighting urgent and critical knowledge gaps which need to be taken seriously for future development in the lmb.
