“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 Program Research Associate Tyler Eddy will be participating in the fifth IMBeR (Integrated Marine Biosphere Research Project) IMBIZO, which will be hosted by the Ocean, Carbon & Biogeochemistry Group…
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.
From November 2 to 13, the North Pacific Marine Science Organization (PICES) held their annual meeting in San Diego, USA. The meeting celebrated the 25th anniversary of PICES with the theme of looking at the past 25 years and imagining the next 25. Some of the topics of interest included coastal ecosystem stressors, loss or changes of marine biodiversity, changing productivity and species distributions in response to climate change, developing outlooks or forecasts of future ocean ecosystems, and examining climate change impacts on ocean ecosystems and human society.
Nereus Fellow at Princeton Colleen Petrik will be giving a plenary talk entitled “The Response of Fisheries Production to Natural and Anthropogenic Forcing: Past, Present and Future” at the PICES Annual Meeting in San Diego. The talk presents a mechanistic model to represent immature and mature stages of forage fishes, large pelagic fishes, and large demersal fishes, as well as preliminary of fish biomass under (1) pristine non-anthropogenic historical forcing (no anthropogenic CO2, no fishing), (2) historical climate without fishing, (3) historical climate with fishing, (4) and projected business-as-usual climate and fishing.
