Research priorities for seafood-dependent livelihoods under ocean climate change extreme events
Financiado para publicación en acceso aberto: Universidad de Vigo/CISUGThe current magnitude of ocean extreme events already
exceeds the end-of-the-decade scenario estimates, and
therefore incremental adaptation measures will render
insufficient for seafood-dependent livelihoods.
Nevertheless, transformational change is deemed
promising, but uncertainties remain as to what activates
such processes and how maladaptation outcomes can be
avoided. While the science on extreme events is advancing
fast, little is known about livelihood adaptation and
transformation processes in the context of single or
compound ocean extreme events. We identify a set of
research priorities: 1) the identification of hotspot areas for
coastal compound extreme events, 2) the development of
bottom-up case study analysis of adaptation to extreme
events, 3) the identification of constrainers and enablers to
livelihood adaptation and transformation under abrupt
change, and 4) directing research to contribute to climatechange
policy. An effort addressing these key gaps will
inform seafood-dependent livelihood adaptation policies for
the 2030 Agenda and beyond
Food security challenged by declining efficiencies of artisanal fishing fleets: a global country-level analysis
Financiado para publicación en acceso aberto: Universidade de Vigo/CISUGGlobal capture fisheries are a vital global food provisioning to help end hunger and malnutrition. To ensure that global seafood supply sustainably supports a growing population, many initiatives within the UN Sustainable-Development-Goals seek to balance management with efficient resource use. Here we examine changes for 150 countries that represent over 98% of global catch for the 1950–2014 period by analysing multiple fleet outputs relative to inputs (such as vessel power) using data envelopment analysis. We show that country specific technical efficiency has declined at rates of −3% yr−1 for artisanal and industrial fleets in 44 and 49 countries respectively. Recent global artisanal fleet (2010–2014 average) declines of −0.2%yr−1 show losses that translates to ∼71400t posing serious implications for sustainable food security and vulnerable livelihoods in the face of climate chang
