As part of a Major research project investigating the local effectiveness of the HYOGO framework, Gamos has analysed data gathered through innovative SMS based surveys. 36,000 reposes were gathered from amongst those living in disaster affected countries. In partnership with GNDR, Gamos has analysed the experience of this eSurvey project to identify the critical success factors. Along with many other benefits, this survey technology has the potential to maximise the opportunity created by dramatic recent increases in mobile phone usage in many low to middle income countries.
