Compared to historical times, there has been an increase in the frequency of reportings of jellyfish sightings in coastal waters. Based on a few regional case studies, many have gathered that jellyfish population sizes are exploding due to warming waters. However, there are not a lot of datasets to support this. Natasha Henschke addressed this topic in her research completed during her fellowship with the Nereus Program.
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.
Nereus Program Fellow Richard Caddell attended the “Natural Marine Resource Management in a Changing Climate” Workshop between June 12 to 13, 2017 at the University of Tromsø in Norway. Discussion at the workshop addressed how regulations might evolve in response to shifting fish stocks due to ocean warming and acidification.
The United Nations Ocean Conference to “Support the Implementation of Sustainable Development Goal 14” was held in New York at the UNHQ between June 5 and 9, 2017. On Friday June 9, the Nereus Program hosted a side event, ‘The Role of the Oceans in Sustainability: Benefits of Achieving SDG 14 for all Sustainable Development Goals,’ at the conference. This side event introduced recent research that evaluates how achieving ocean SDG 14 targets contributes to- and in some cases is required for – the achievement of other SDG targets.
Developing nations, which have contributed little to the issue of climate change, are likely to experience reduced livelihood opportunities and emerging dietary nutrient deficiencies as a result of climate change impacts on fisheries.
A healthy ocean will benefit global sustainable development in a number of ways, finds a new report published today by the Nippon Foundation-Nereus Program. With climate change and social inequity addressed, restoring the ocean will help alleviate poverty, provide livelihoods, and improve the health of millions around the world.
We know that fuel use contributes to climate change, but in a vicious circle, climate change could also increase fuel use in fishing. This is due to fish shifting their distributions due to warming waters. With this increased use of fuel and the increasing price, small-scale and artisanal fishers will have a harder time sustaining livelihoods and feeding their families under climate change.
Mangrove forests, made up of shrubs and trees with sprawling roots that grow in salt water, provide many services to humans and marine ecosystems. They sequester carbon, pulling it from the atmosphere, and prevent erosion of coastal areas. Due to their unique characteristics, mangrove forests provide an important source of food and shelter for marine species, including many important fisheries. Mangroves cover 150,000 km² of coastline in tropical and warm temperate regions around the world. Rachel Seary, Nereus Fellow at Cambridge/UNEP-WCMC, is currently conducting research to understand both the direct benefits that mangroves have on communities living and fishing within their vicinity and also the indirect benefits that mangroves may have on coastal fisheries productivity in Bali, Indonesia.
