Citizen Science for Observing and Understanding the Earth

Since the end of 2015, I’ve been using the following mapping of citizen science activities in a range of talks:

Range of citizen science activities
Explaining citizen science

The purpose of this way of presentation is to provide a way to guide my audience through the landscape of citizen science (see examples on SlideShare). The reason that I came up with it, is that since 2011 I give talks about citizen science. It started with the understanding that I can’t explain extreme citizen science when my audience doesn’t understand what citizen science is, and that turned into general talks on citizen science.

Similarly to Caren Cooper, I have an inclusive approach to citizen science activities, so in talks, I covered everything – from bird watching to DIY science. I felt that it’s too much information, so this “hierarchy” provides a map to go through the overview (you can look at our online course to see why it’s not a great typology). It is a very useful way to go through the different aspects of citizen science, while also being flexible enough to adapt it – I can switch the “long-running citizen science” fields according to the audience (e.g. marine projects for marine students).

An invitation for Pierre-Philippe Mathieu (European Space Agency) in 2015 was an opportunity to turn this mapping and presentation into a book chapter. The book is dedicated to “Earth Observation Open Science and Innovation and was edited by Pierre-Philippe and Christoph Aubrecht.

When I got to writing the chapter, I contacted two researchers with further knowledge of citizen science and Earth Observation – Suvodeep Mazumdar and Jessica Wardlaw. I was pleased that they were happy to join me in the effort.

Personally, I’m very pleased that we could include in the chapter the story of the International Geophysical Year, (thank Alice Bell for this gem), with Moonwatch and Sputnik monitoring.

The book is finally out, it is open access, and you can read our chapter, “Citizen Science for Observing and Understanding the Earth” for free (as well as all the other chapters). The abstract of the paper is provided below:

Citizen Science, or the participation of non-professional scientists in a scientific project, has a long history—in many ways, the modern scientific revolution is thanks to the effort of citizen scientists. Like science itself, citizen science is influenced by technological and societal advances, such as the rapid increase in levels of education during the latter part of the twentieth century, or the very recent growth of the bidirectional social web (Web 2.0), cloud services and smartphones. These transitions have ushered in, over the past decade, a rapid growth in the involvement of many millions of people in data collection and analysis of information as part of scientific projects. This chapter provides an overview of the field of citizen science and its contribution to the observation of the Earth, often not through remote sensing but a much closer relationship with the local environment. The chapter suggests that, together with remote Earth Observations, citizen science can play a critical role in understanding and addressing local and global challenges.



Chapter in Routledge Handbook of Mapping and Cartography – VGI and Beyond: From Data to Mapping

Hot on the heels of the Routledge Handbook of Environmental Justice is thThe Routledge Handbook of Mapping and CartographyRoutledge Handbook of Mapping and Cartography. The handbook was edited by Alex Kent (Canterbury Christ Church University) who is currently the President of the British Cartographic Society and Editor of The Cartographic Journal; and Peter Vujakovic (also from Canterbury Christ Church University) who edited The Cartographic Journal.

Like the other handbooks, this is an extensive collection of 43 chapters and almost 600 page about maps and mapping. The chapters provide a vivid demonstration that cartography and map making is art and science, and that it links to many sciences and practices – from cognitive psychology to geodesy. The list of authors is impressive and includes many of the people that are shaping current cartographic research.

However, with a price tag of £195 for the Book, this collection is expensive and suitable for university libraries and to professional or commercial mapping organisation. The eBook is £35, which makes it much more affordable, though having used the online system, the interface could be better. Luckily the policy of Routledge permits sharing the chapters on personal websites.

My contribution to the book is in a joint paper that was led by Vyron Antoniou titled VGI and Beyond: From Data to Mapping. The chapter is building on a collaboration between Vyron, myself and Cristina Capineri during the COST Action on Volunteered Geographic Information (ENERGIC). In the chapter, we look at the concept of Volunteered Geographic Information (VGI) within practices of mapping and cartography and we attempted to provide an accessible overview of the area. We define what VGI is, provide an overview of the area, look at the advantages and disadvantages of VGI in mapping and cartography, and then look at the impacts of VGI on national mapping agencies, the public, and public bodies. The chapter is available here and we would be very happy to hear comments on it.



New Paper: The Three Eras of Environ-mental Information: the Roles of Experts and the Public

Since the first Eye on Earth conference in 2011, I started thinking that we’re moving to a new era in terms of relationships between experts and the public in terms of access to environmental information and it’s production. I also gave a talk about this issue in the Wilson Center in 2014. The three eras can be summarised as ‘information for experts by experts’,’information for experts and the public, by experts, and in experts language’, and ‘information for experts and the public, by experts and the public, in multiple forms’.

Finally, as part of a book that summarises the outcomes from the EveryAware project, I’ve written a chapter that explores the three eras of environmental information and provide a more detailed account of each of them.  You can access the paper here and it should be cited at

The book includes many other chapters and I’ll put several of them online later in the year. you can find the book on Springer site.
