“The intersectoral and interdisciplinary nature of the ISIMIP approach meant that topics were very broad and spanned both land and sea, natural science, social science, economics, human health, and policy,” said Tyler Eddy. “This perspective was very interesting to consider big ideas and issues at broad scales, however as a result of this broad approach, detailed ocean processes weren’t covered as much.”
Nereus Director of Science William Cheung has won the Prix d’ Excellence Award by the International Council for the Exploration of the Sea (ICES). The Prix d’Excellence is awarded every three years for a high level of achievement in marine sciences work through research, scientific leadership and scientific policy leadership.
Climate change and human activity have pressing impacts on the state of our ocean, threatening the integrity of marine ecosystems themselves as well as the services they provide to human communities. Given the inevitable current and future effects of climate change, adaptation by both physical and human systems is crucial.
Nereus Program Fellow Becca Selden (Rutgers University) helped plan and execute a symposium on “Marine Species on the Move” at the American Fisheries Society’s 147th Annual Meeting in Tampa, Florida from August 20 to 24, 2017.
Developing countries face decreases in both fisheries and agriculture production under climate change
The authors looked at how food production on land and in the sea will be threatened by climate change and what the future effects on biodiversity, livelihoods and food security will be. They adopted the human development index (HDI) — a global index of life expectancy, education and per capita income. They found that all of the low human development index countries will face declines in both agriculture and fisheries production by 2050.
The rapid development of fisheries in the 1950’s facilitated declines in predator biomass, overexploitation, collapse of fish stocks, and degradation of marine habitats. A new PLOS ONE paper investigates past changes in trophic functioning of marine ecosystems cause by human-induced changes in species assemblages by applying an ecosystem approach to fisheries.
Fish are expected to shrink in size by 20 to 30 per cent if ocean temperatures continue to climb due to climate change. A new study by researchers at the Nippon Foundation-UBC Nereus Program provides a deeper explanation of why fish are expected to decline in size.
A new paper, ‘A rapid assessment of co-benefits and trade-offs among Sustainable Development Goals‘, has been published in Marine Policy and includes contributions from various Nereus affiliates. This study highlights how achieving SDG 14: Life Below Water targets contributes to the accomplishment of other SDGs
Coastal ecosystems are undergoing complex changes caused by both social and ecological drivers occurring at varying scales and speeds, which ultimately act as either risks or opportunities to coastal social-ecological systems. The assessment of adaptive capacity of coastal ecosystems is crucial in understanding the extent to which they will be able to accept and adapt to these social and biophysical drivers.
