Figure for Thought: River Systems are People Systems Too

A working group from the Science and Nature for People Partnership (SNAPP) posits that it is time for river management to account for a crucial element of river ecosystems: people.  



A Unique Honor for Ocean Science

Boat International awards NCEAS' executive director Ben Halpern for his work to include oceans in the Planetary Boundaries framework. Halpern catches us up on that work and what this award means for ocean health. 



Farming Fish Saves Land

If our future global population ate more seafood from aquatic farming, or aquaculture, to satisfy the anticipated growth in their protein needs, we may be able to substantially reduce one of the biggest environmental impacts of meat production – land use – without giving up meat entirely.



Telling the Hidden Stories of Salmon

The diversity of relationships between salmon and people in Alaska have been largely absent from the thinking that typically informs salmon management. A research collaboration is seeking to remedy this and support management by making visible the multiplicity of human experiences that are both impacting and impacted by salmon systems in the state.

NCEAS Portrait: Eric Ward Uses Economics to Analyze Ecosystems

Eric Ward epitomizes a synthesis scientist. By combining ecology, statistics, mathematical modeling, and even economics, he brings together multiple disciplines to study how ecosystems in the Northwestern U.S. respond to environmental change.

A quantitative ecologist and fisheries expert, Ward co-leads our Gulf of Alaska Portfolio Effects working group. His team is using novel methods to improve understanding of the effects of the Exxon Valdez oil spill and other environmental changes on aquatic species and fisheries.



Too Many Salmon in the Sea?

Recording-setting abundance of some salmon species in the North Pacific may be having negative impacts on other salmon species, namely the prized Chinook. This is the first study to emerge from our partnership project The State of Alaska Salmon and People (SASAP).



SNAPP: Food and Forests in Africa

Principal Investigator(s): 

Phil Franks

Food demand in Sub-Saharan Africa is expected to triple by 2050. This puts Sustainable Development Goals 2 (ending hunger) and 15 (protect terrestrial ecosystems) at odds as conversion to agriculture is the primary driver of deforestation. Working in Ethiopia, Ghana and Tanzania and building on previous efforts by the International Institute for Environment and Development, this group combines spatial and political economy analysis to better reconcile these competing goals.

SNAPP: Steppe Health

Principal Investigator(s): 

Amanda Fine and Enkhtuvshin Shiiledgdamba

Infectious diseases at the livestock/wildlife interface threaten the health and well-being of wildlife, livestock, and human livelihoods. Using data from the recent Mongolian outbreak of peste des petits ruminants (PPR) that killed tens of thousands of livestock and more than half of the endangered saiga antelope population, the project will look at the potential for participatory epidemiology, or bottom-up surveillance by the pastoralists themselves, as the most effective way to prevent future outbreaks.

SNAPP: Water Flow Impact

Principal Investigator(s): 

Kari Vigerstol, Adrian Vogl, and Robin Abell

While source water protection programs are often implemented in response to hydrological shifts caused by climate change and land degradation, there is little empirical evidence about how these activities affect the quantity of water downstream. This project will investigate to what extent, and under what circumstances, source water protection activities can produce meaningful baseflow, groundwater recharge, and flood impacts.
