2050: Sustainable oceans in a changing climate

Which fish species will we be eating in 2050? What will the climate be like, and what will it mean for the productivity of the oceans? And how can we turn fisheries management around so that we harvest sustainably and ensure the livelihoods of fishing communities in the future?

These are three of the questions a diverse group of academics from the Cabot Institute tackled at the inaugural Cabot Writing Day in January. The concept for the event was that invitees from a range of disciplines (in this case marine biologists, lawyers, earth scientists, geographers and NGO representatives) gathered to address a central theme, and in a day produce a position paper:

2050: Sustainable oceans in a changing climate

As you can see we covered a huge amount of ground, gained valuable insights from each other's disciplines, share personal viewpoints and (deliberately) envisaged a very positive future for fisheries in 2050.

We are now using our discussions to fuel ideas for grant applications, initiate new contact and interaction with industry and policymakers, and potentially develop a TV series.

If you would like help organising a Cabot Writing Day on a subject you think needs attention and which suits the diverse Cabot Institute community, please contact Stephen.Simpson@bristol.ac.uk (Cabot KE Fellow) or Philippa.Bayley@bristol.ac.uk (Cabot Manager) to discuss your ideas...

Converting probabilities between time-intervals

This is the first in an irregular sequence of snippets about some of the slightly more technical aspects of uncertainty and risk assessment. If you have a slightly more technical question, then please email me and I will try to answer it with a snippet. Suppose that an event has a probability of 0.015 (or 1.5%) of happening at least once in the next five years. Then the probability of the event happening at least once in the next year is 0.015 / 5 = 0.003 (or 0.3%), and the probability of it happening at least once in the next 20 years is 0.015 * 4 = 0.06 (or 6%). Here is the rule for scaling probabilities to different time intervals: if both probabilities (the original one and the new one) are no larger than 0.1 (or 10%), then simply multiply the original probability by the ratio of the new time-interval to the original time-interval, to find the new probability. This rule is an approximation which breaks down if either of the probabilities is greater than 0.1. For example

Cabot office weekly roundup – 20 July 2012

Herbert Huppert This week we have been holding our Cabot Summer School on risk and uncertainty in natural hazards . The week has gone very well and I have received some very positive comments from attendees. We had some fantastic speakers including Herbert Huppert, Jonty Rougier, Steve Sparks, Willy Aspinall, Li Chen, Tamsin Edwards, Philippa Bayley and Thorsten Wagener. Cabot would like to say a great big thank you to all of you for making the Cabot Summer School such a success. We’re very much looking forward to next year. Paul F. Hoffman This week, Cabot member Rich Pancost secured Paul F. Hoffman of Snowball Earth fame as the next Science Faculty Colloquium speaker in September. I saw the new templates for our website today. Its all looking good and I’m quite excited about the implementation of its new look. By the end of the summer I hope to have it all up and running. We would like to congratulate Cabot member Professor Mark Eisler and

Discussing Rio+20 at the House of Lords

Last month I went to the House of Lords for a meeting of the All party group for international development and the environment. The morning’s question was: Where next for sustainable development after Rio+20? I’ll give a brief resume of who said what, with some of my thoughts following over the next weeks.... Joan Walley , MP for Stoke-on-Trent North opened the morning's reflections on Rio. She chairs the Environmental Audit Committee which monitors action across different government departments. At the top level, Rio lacked vision and clear objectives. Her select committee really tried to engage with government, but there was no commitment from the PM that he was going, and no clear vision from them. She felt the process needs to be reinvigorated - connecting, collaborating, and understanding the details - e.g. how the proposed Sustainable Development Goals will link with the Millennium Development Goals. Stephen Hale from Oxfam asked how do we accelerate the p
