The 2016-2025 IMBeR Science Plan and Implementation Strategy has been ratified!

After an intensive consultation and review process that began in 2012, the IMBeR Science Plan and Implementation Strategy (SPIS) has now been sanctioned by IMBeR’s sponsors – the Scientific Committee on Oceanic Research (SCOR) and Future Earth. The SPIS outlines IMBeR´s research agenda until 2025, towards its vision of Ocean sustainability under global change for the benefit of society.

New CLIOTOP special issue - Tunas and their fisheries: safeguarding sustainability in the twenty-first century

Tuna are one of the pelagic species central to IMBeR´s CLIOTOP regional programme. The relationship of tunas to their environment has been studied for decades and is increasingly important as the effects of climate change become more apparent in the pelagic environment. Recent studies relating climate change to changes in movements and distributions of tunas are based on physiological studies on tunas and awareness of species-specific suitable habitats. This special issue focuses on these commercially and ecologically important species, with contributions on species, life history stages, fisheries, and bycatch, with the following contributions.

Expanding marine predator isotope work: community-level metrics, mercury isotopes, and data-model linkages

Ecological applications of stable carbon and nitrogen isotope analysis are rapidly expanding through the analysis of metadata. Recent efforts of the IMBeR CLIOTOP Task Team on Marine Predator Isotopes have focused on finalising an open-access data paper and three research papers that present novel findings of global scale, spatial and temporal analyses on migratory tuna muscle isotopes. The task team recently met in Brest, France to discuss novel ways to expand our ecological understanding of the ocean. The main approaches included formulating community level metrics, using isotopes of mercury, and finding practical ways to link isotopic data with ecosystem and biogeochemical models.

Governing fisheries through the critical decade: the role and utility of polycentric systems

The next 10 years are considered a critical decade for fisheries. Declining fish stocks in combination with mounting climate pressure are likely to lead to significant and adverse socio-ecological impacts, threatening sustainability. Responding to these challenges requires modes of governance that are capable of dealing with the complexity and uncertainty associated with the world’s fisheries and their ecosystems. While a range of governance frameworks exist, the concept of polycentric governance has gained prominence in the environmental sector and is posited as a key principle underpinning the resilience of complex socio-ecological systems. However, the application of polycentric governance to fisheries management has been seldom explored. To address this, a new paper in Reviews in Fish Biology and Fisheries by Chris Cvitanovic, Alistair Hobday, Ingrid van Putten and others reviewed the literature on polycentric governance to elucidate its potential value in improving the outlook for fisheries and their associated ecosystems. They identify a number of characteristics unique to polycentric governance arrangements that overcome known limitations in other forms of governance - polycentric systems are highly participatory and promote the broadest levels of stakeholder involvement, they increase policy freedom at the local level, and they improve the spatial fit between knowledge, action and socio-ecological contexts to ensure that governance responses are implemented at the most appropriate scale. Through fisheries case-studies, they then demonstrate that these characteristics are important in helping fisheries respond to complex challenges, and articulate future research needs that should be addressed to understand the conditions under which polycentric governance systems are most suited, and the ways in which they can be operationalised most effectively.
