The Severn Estuary Forum is a key annual event in its eighth year and hosted by the Severn Estuary Partnership: an independent, estuary-wide initiative, involving all those interested in the management of the estuary, from planners to port authorities, fishermen to farmers.

This year’s Forum was opened by the Lord Mayor of Gloucester and supported by CIWEM. It focussed on a number of diverse topics, including the upper estuary; renewable energy possibilities; a review of the Severn Estuary Flood Risk Management Strategy; an overview of the operations and maintenance of the Severn River Crossings; Local Enterprise Partnerships; The Bristol Deep Sea Container Terminal; proposals for a Severnside Airport and Fisheries amongst others.

These engaging and exciting events are intended for all interested in learning about the latest research and policy developments dealing with the Severn Estuary and its future, and always guarantee a lively and informative day of presentations and talks. They offer a unique opportunity to learn from others, share ideas and participate in the management of the Severn Estuary.

  • Who I am, what I’m going to talk about
  • Business When the governments Low Carbon Industrial Strategy was announced in July 2009, the south west was designated as the Low Carbon Economic Area for Marine Energy. This was the first low carbon economic area to be identified. Apart from the honour, this designation brought with it additional funding which, together with funding from our European Partners and the south west RDA has been used to support the development of marine energy in the region and to invest in institution such as PRIMaRE. The PRIMaRE stand is at the back of the room, and if you take the time to talk to them you will hear about the research work that is being done at the universities of Exeter and Plymouth.The purpose of Low Carbon Economic Area is to develop jobs and industry.And in the south west the backbone of our industrial capability is our Maritime and engineering heritage. Many of these businesses are based around our hub ports – Portland, Plymouth, Falmouth and Bristol - others are now part of the Hi Tech and low carbon industries which have been growing around the region.In fact many are here today – I know that Regen SW has been overwhelmed by the amount of interest shown in this conference. Partly this is because it is free and there will be drinks at the end – but it also it demonstrates the interest that there is in the renewables sector and the willingness of businesses and entrepreneurs to explore new opportunities to start-up and grow their enterprise.
