title: Islandness: Vulnerability and resilience in Oceania

authors: Campbell, John

subjects: vulnerability

abstract: Pacific and other islands have long been represented as sites of vulnerability. Despite this, communities on many Pacific islands survived for millennia prior to the intrusion of people from Europe into their realm. An examination of traditional disaster reduction measures indicates that traditional Pacific island communities coped with many of the effects of extreme events that today give rise to relief and rehabilitation programmes. Key elements of traditional disaster reduction were built around food security (production of surpluses, storage and preservation, agro-ecological biodiversity, famine foods and land fragmentation), settlement security (elevated sites and resilient structures) and inter- and intra-community cooperation (inter-island exchange, ceremony and consumption control). Many of these practices have been lost or are no longer employed, while other changes in the social and economic life of Pacific island communities are increasing the level of exposure to natural extremes. Pacific islands, and their inhabitants, are not essentially or inherently vulnerable. They were traditionally sites of resilience. Colonialism, development and globalisation have set in place processes by which the resilience has been reduced and exposure increased.

title: Environmental context determines pollution impacts on ecosystem functioning

authors: Burdon, Francis J.

abstract: Global change assessments have typically ignored synthetic chemical pollution, despite the rapid increase of pharmaceuticals, pesticides and industrial chemicals in the environment. Part of the problem reflects the multifarious origins of these micropollutants, which can derive from urban and agricultural sources. Understanding how micropollutants harm ecosystems is a major scientific challenge due to asymmetries of stress across trophic levels and ecological surprises generated by multiple drivers interacting in human-impacted landscapes. We used field assays above and below municipal wastewater treatment plants (WWTPs) in 60 sampling locations across 20 Swiss streams to test how micropollutants and nutrients originating from WWTPs affect two trophic levels (microbes and detritivores) and their role in leaf litter processing. Wastewater impacts were asymmetric across trophic levels, with the detritivore contribution declining relative to microbial-driven decomposition. The strength of negative impacts were context dependent, peaking at sites with the highest upstream abundances of detritivorous invertebrates. Diffuse pollution from intensive agriculture and wastewater-born micropollutants contributed to reduced litter processing rates, including indirect effects apparently mediated through negative influences of insecticides on detritivores. Asymmetries in stress responses across trophic levels can introduce quantitative changes in consumer–resource dynamics and leaf litter processing. This means functional redundancies at different trophic levels are insufficient to compensate for biodiversity losses, causing environmental stressors such as chemical pollutants to have pervasive ecosystem-level impacts.

title: The Critical Juncture in Aotearoa New Zealand and The Collective Future: Policy Issues in Settler/Invader Colonial Zombiism Found in “Biculturalism”

authors: Simon, Hemopereki

abstract: This theoretical Kaupapa Māori writing inquiry study seeks to explore the settler colonial nature of Aotearoa New Zealand. The research finds that biculturalism, as a neo-liberal and settler-colonial construct does not provide for either tino rangatiratanga or mana motuhake. Indeed, biculturalism fails to provide for indigenous inclusion and actively suppresses the recognition of mana motuhake. Biculturalism is found to fit Beck’s definition of Zombie Concepts. These are social concepts that are dead and yet kept alive in their use by scholars and society to describe the growing fiction of traditional social institutions and in being kept alive maintain, in this case, settler colonial and colonial power structures. The main argument is that Biculturalism is neoliberal and settler colonial public discourse, that needs to be unpacked and then discarded because it does not provide for tino rangatiranga or mana motuhake.
