Recently, I attended a meeting with people from a community that is concerned with vibration and noise caused by a railway near their homes. We have discussed the potential of using citizen science to measure the vibrations that pass the sensory threshold and that people classify as unpleasant, together with other perceptions and feeling about these incidents. This can form the evidence to a discussion with the responsible authorities to see what can be done.

As a citizen science activity, this is not dissimilar from the work carried out around Heathrow to measure the level of noise nuisance or air pollution monitoring that ExCiteS and Mapping for Change carried out in other communities.

In the meetings, the participants felt that they need to emphasise that they are not against the use of the railway or the development of new railway links. Like other groups that I have net in the past, they felt that it is important to emphasise that their concern is not only about their locality – in other words, this is not a case of ‘Not In My Back Yard’ (NIMBY) which is the most common dismissal of local concerns. The concern over NIMBY and citizen science is obvious one, and frequently come up in questions about the value and validity of data collected through this type of citizen science.

During my masters studies, I was introduced to Maarten Wolsink (1994) analysis of NIMBY as a compulsory reading in one of the courses. It is one of the papers that I keep referring to from time to time, especially when complaints about participatory work and NIMBY come up.
Inherently, what Wolsink is demonstrating is that the conceptualisation of the people who are involved in the process as selfish and focusing on only their own area is wrong. Through the engagement with environmental and community concerns, people will explore issues at wider scales and many time will argue for ‘Not in Anyone’s Back Yard’ or for a balance between the needs of infrastructure development and their own quality of life. Studies on environmental justice also demonstrated that what the people who are involved in such activities ask for are not narrow, but many times mix aspects of need for recognition, expectations of respect, arguments of justice, and participation in decision-making (Schlosberg 2007).

In other words, the citizen science and systematic data collection are a way for the community to bring to the table evidence that can enhance arguments beyond NIMBY, and while it might be part of the story it is not the whole story.

For me, these interpretations are part of the reason that such ‘activism’-based citizen science should receive the same attention and respect as any other data collection, most notably by the authorities.

The Experienced Noise

3 June, 2008

While the new Defra noise maps provide the results of a computerised model, the experience of noisy places can be mapped through community mapping, as was demonstrated recently in the Royal Docks area and the Pepys Estate.

Within the Mapping Change for Sustainable Communities project, and through the collaboration with London Sustainability Exchange and London 21 projects on Environmental Justice and with the help of Christian Nold, we have recently carried out studies of noise in two areas in east London. While the method is based on a systematic data collection framework, it does not intend to replace detailed acoustics studies that the authorities should carry out regarding sources of noise which influence residential areas. What it does is enable communities to get evidence about their experience, the maximum levels of noise that they are exposed to and to identify the sources of noise that influence the specific place.

The following text is taken from the press release that we have just issued:

People living in the Pepys Estate in Lewisham and in the Royal Docks area in Newham have led the way with a new way to tackle noise. The Pepys Estate currently suffers noise pollution from a scrapyard near the centre of the estate and very close to both a primary and nursery school, while Royal Docks suffers noise problems resulting from flights in and out of London City Airport (LCA), where a major expansion is threatened.

The project supplied local residents with noise meters and trained them in how to use these devices. They went on to make over 1500 measurements at all times of day and night and developed their own ‘noise maps’.

The results of this ‘citizen science’ have been remarkable. On the Pepys Estate members of the Community Forum found disturbingly high levels of noise, often continuing outside normal working hours. This noise affected quality of life up to 350 metres from the scrapyard. They have been trying to deal with this problem for over six years, initially raising concerns with the Mayor of Lewisham and others in September 2002. Since this time the disturbance has actually escalated. Now armed with this information they called a public meeting to present their findings to the council and the Environment Agency.

Lewisham Council and the Environment Agency accept that there is a problem. After seeing the results of the survey the Agency has appointed an acoustic consultant to carry out a detailed analysis of noise in and from the scrapyard. The residents who carried out the survey will meet with the consultant to share their information, and will work with the council to agree an action plan for moving forward.

The communities surrounding London City Airport (LCA), including Virginia Quays and Thamesmead, also found troubling results. Many readings exceed levels deemed to cause serious annoyance under the World Health Organisation community noise guidelines. The measurements gathered by the community revealed a clear correlation between unacceptable levels of noise and the LCA operational hours. More interestingly, the results obtained by both communities indicate that people are quite accurate in their perceptions of noise levels and the survey enabled them to express how these affected them. One of the residents said ‘the noise is irritable, I can’t relax or have the window open – but I can’t shut out the noise so have to turn the TV up – but everything is then so loud.’
