Sistema chief executive Nicola Killean said:"Peter has been a true asset to the organisation since he joined us in 2009, and I am positive he has the passion, experience and ambition we need to embark upon our next ten years of making
a Big Noise in communities across Scotland."
Organisers of the Cardiff Festival summer celebration are hoping that the audience of 10,000 will take part in Make a Big Noise, which will be recorded and played to world leaders at the World Summit for Sustainable Development in South Africa this summer.
Craig Owen, Oxfam Cymru campaigns co-ordinator, said: ``Whilst enjoying ourselves at the MAS Carnival, I hope that people will remember that we can all act to make the world a more equitable and sustainable place and, by making a Big Noise, remind world leaders that trade can be a powerful tool to combat poverty.''
