Biography

Nick Drake obtained his BSc (Honours) in Environmental Science at Plymouth Polytechnic in 1983 and his Master of Applied Science in Geochemical Exploration from the University of New South Wales in 1986.

From 1986 to 1992 Nick worked as a research fellow conducting remote sensing research at the Department of Geography, Reading University. He worked on the development of improved algorithms for image classification and the characterisation of desert surfaces for geomorphological mapping using remote sensing. During this time he completed a part-time PhD entitled ‘Mapping and monitoring of surface cover types and processes in southern Tunisia using remote sensing’.

Nick joined King's Department of Geography in 1992, was made Reader in 2000 and a Professor in 2013. He has continued to develop his interests in theoretical and practical aspects of remote sensing while broadening his interests into geographical information systems and spatial modelling.

During the last few years Nick's interests have focussed on applying his expertise to arid lands and, in particular, the Sahara Desert. He is the leader of the Sahara Megalakes Project, an international project that involves nine universities and coordinates research on giant ancient lakes in Chad, Libya and Tunisia. He is a member of the editorial board of the Journal of Arid Environments, Origini (Journal of Prehistory and Protohistory of Ancient Civilizations) and the Journal of Geology & Geosciences.

Nick has published 65 single and joint authored journal articles, 22 book chapters, 31 published conference proceedings and was co-editor of Spatial Modelling of the Terrestrial Environment published by Wiley in 2004. He is a member of:

  • the Remote Sensing and Photogrammetric Society
  • the Royal Geographical Society
  • the British Society for Geomorphology.

Nick has been most active in the Remote Sensing and Photogrammetric Society where he has organised a number of sessions for annual conferences, was invited to become a member of the organisation committee of their Special Interest Group in Modelling and Advanced Techniques in 1997, and was the group convenor from 1999 to 2004.

Nick now plays a prominent role in the Society for Libyan Studies. Between 2002 and 2006 he was a council member, from 2004 to the present has been on the society’s publications committee and in 2008 he was appointed the society’s Honorary Secretary.

Nick has played an active role in departmental, King's and University of London administration. He joined the University of London Subject Area Board (SAB) for Mathematical and Physical Sciences in 1998. He was invited to be Deputy Chair in 2004. In 2005 he was appointed to the University of London Senate and became the chairman of the SAB in 2006.

Research

Nick Drake has research interests in remote sensing, GIS, spatial modeling, geomorphology, geoarchaeology and environmental change. He specialises in applying expertise in these areas to semi-arid and arid environments. His research interests in remote sensing involve both theoretical and practical aspects while research in GIS includes implementing spatial models of land degradation, soil erosion and wildlife distributions. 

His interests in climate change and geoarchaeology assimilates much of the above mentioned expertise by employing remote sensing and GIS to map the palaeohydrology of arid regions; using this information to locate geomorphological sites of likely geoarchaeological interest; and investigating them using field and laboratory methods in order to determine their paleaeo-environmental and archaeological significance.

This research is currently concentrating on past human occupation and climate change in the Sahara particularly the evidence provided by lacustrine sediments deposited by giant palaeolakes once located in the large closed basins of the Fezzan (Libya), the Chotts (Tunisia) and the Bodele (Chad). This research is coordinated by the Sahara Megalakes Project.

These Saharan megalakes provide information for furthering our understanding not only of the palaeoclimate of the Sahara but also African biogeography and palaeoanthropology. The Sahara Desert currently provides a formidable barrier to animal and hominid migration from central/southern Africa to Arabia and the Levant. However, there is abundant evidence that on several occasions in the past, creatures which evolved in central/southern Africa were able to populate adjacent landmasses, indicating that this barrier did not always operate.

Understanding the long-term climatic evolution of the Sahara region is therefore a particularly important question for biogeography and palaeoanthropology. By chance, the catchments of the three megalakes (Lake Megachad, Lake Megafezzan and the Chotts Megalake) link to form a corridor across the Sahara. Thus the palaeolake sediments they preserve can be used to determine whether there was previously a corridor of humidity across the Sahara by looking for evidence of synchronous lacustrine activity in all three basins.

Nick has recently expanded this work into the Arabian Desert as part of the Palaeodeserts Project.

Three minutes with Nick Drake - an interview

Were you fascinated by geography as a child?

Not to start with, I was more interested in geology, collecting rocks and minerals whenever I got the chance. When I was 12, I went on a trip to Ghana. We went up the Volta River in a speedboat and met some local fishermen who’d caught this enormous fish. They wanted to give us the fish, and stupidly, I took it – they must have been quite poor... I think that trip gave me a sense of adventure that I’ve wanted to replicate throughout my life. It was this that ultimately led me to geography.

What made you go into this field?

I was really interested in geology. I did a BSc in Environmental Science at Plymouth and took all the geology courses. And then I did a Master’s in Geochemical Exploration at New South Wales so that I could spend the rest of my life exploring the world looking for minerals. While I was there, I shared an office with a guy who was studying geography and it struck me that he had a good balance of university-based work and fieldwork. So that’s when I decided to go in this direction and did my PhD in Remote Sensing in the Geography Department at Reading University.

What has your research on the Sahara Megalakes Project revealed?

The Sahara Desert was home to some of the world’s largest freshwater lakes five to ten thousand years ago (and in previous interglacials). The project has investigated these lakes and has given us a better understanding of past climate change and the distribution of species, ecosystems and archaeology in the region.

Which countries have you travelled to whilst conducting your research?

Recently I have been to Sudan, Libya, Tunisia, Nigeria and Saudi Arabia. The most interesting area is probably the Ubari Sand Sea in Libya. Logistically it’s tough to travel there. You have to take all your water and fuel with you, and spare vehicle parts. Hardly anyone has been there, so there’s a lot to be found. There are cliffs of lake sediments 30 metres high formed by a giant lake that at its maximum extent was the size of England.

Any travel mishaps?

Yes, lots – mostly with vehicles. Really you should travel with two vehicles in the desert in case anything goes wrong. I went on an expedition in Sudan where we could only get hold of one vehicle. We were only planning to travel about 80km from Khartoum and had a satellite phone so decided to risk it. Then, of course, the radiator on the vehicle broke down. One of the drivers managed to fix it by putting some tobacco inside – the tobacco expanded to plug up the holes – only to get a flat tyre shortly afterwards. At this point we decided it was time to go back to Khartoum.

What are you planning to do next?

I’m planning to do some research on the Chotts Megalake in Southern Tunisia. I’ll be focusing on climate change and the geological stuff, while the Italian researchers we’re travelling with will focus on archaeological remains.

What kind of things do you hope to find?

Lake sediments, stone tools, animal fossils, [Nick hands me some flat, sharpened stones] these sorts of things. They could be arrowheads or knives – and date from the time of early modern humans, that’s 40 to 140 thousand years ago.

What do you do in your spare time?

I don’t really have a lot of spare time! I write up my research... My family and I are going on a trip to Kenya over the summer though. We’ll spend a week on safari and then explore the Great Rift Valley. I couldn’t go on holiday and just laze on a beach!

Why should students choose to study geography for GCSE, A Level or a degree?

You should study geography because it’s an opportunity to understand the Earth’s environment and the way humans interact with it. And with this information you will be inspired to visit some amazing places.

Teaching

5SSG2043 Environmental Remote Sensing

The module aims to provide a comprehensive understanding of environmental remote sensing. To achieve this students will learn the fundamental characteristics of electromagnetic radiation and how it interacts with earth surface materials. Students will then learn how this radiation is recorded using a wide variety of instruments (e.g. cameras, scanners, RADAR) on a wide range of platforms (e.g. aeroplanes, satellites). The course will then consider the diverse array of applications of remote sensing in geography including topics such as climate change and global warming, tropical deforestation, urbanisation, land use change and geomorphology.

5SSG2053 Principles of Geographical Enquiry II

This module builds on what you did in the first year in PGI I. The aims of this module are to provide a grounding in spatial analysis of geographic data, to introduce you to Geographical Information Systems (GIS), to continue your statistical methodology training from year one and finally, work to prepare you for your Independent Geographical Study (IGS) which you will be doing in your third year. Overall, it is designed to get you to not only think across the human/physical divides in Geography, but to provide you sets of concepts, skills and methods that work to link and cut across this divide.

6SSG3025 Desert Environments

This module aims to provide a comprehensive understanding of the characteristics of desert environments, the environmental problems found in these regions, and the techniques that can be used to assess and mitigate them, using examples from both arid and semi-arid environments. The course enables students to gain an understanding of the important climatic, hydrological, geomorphological and ecological processes that occur in deserts, and examine the ways in which they are affected by human activities. The course considers environments that experience high temperatures and scarcity of water which are highly susceptible to a diverse set of anthropogenic influences leading to desertification. It considers ways to monitor the effects of desertification and ways to rectify these effects. It then considers the policy options for management of deserts, concentrating on the requirements of the UN Desertification Convention.

6SSG3070 (undergraduate) 7SSG5176 (masters) Global Environmental Change I: Past and Present

The specific aims of the module are to review the nature and processes of terrestrial environmental changes experienced during the period of existence of human societies up to and including the present, focusing on changes to the climate, terrestrial carbon cycle, and to Earth's landcover and landuse. By covering variability and change in these areas of the Earth system the module will provide the scientific background necessary to better understand the causes and consequences of environmental changes in isolation and as a whole, whether they be paleo-environmental changes, studies of the contemporary environment, or future projections.

5SSG2049  Methods in Physical Geography

Specific aims of the module are to provide an understanding of research methodologies in physical geography, including their strengths and weaknesses. Equip students with a range of skills to undertake field and modelling research. Prepare students for undertaking the Independent Geographical Study.

At the completion of the module students should be able to understand different methodologies that may be available for physical geography research and the impacts they have on the possible outcomes of that research. Apply GIS and remote sensing techniques to practical projects. Understand different approaches to data analysis. Apply simple statistical and/or numerical modelling approaches. Have some of the necessary research methodology tools to carry out their Independent Geographical Study successfully

5SSG2046 Fieldwork in Physical Geography

The fieldtrip aims to encourage an active engagement with the external world through experiential learning beyond the formal classroom. This provides an opportunity to apply conceptual and methodological skills learned elsewhere in the curriculum to more complex field environments. The module encourages students to develop the ability to identify a problem or research question and to design appropriate methodologies in the field. In doing so it also provides an opportunity to examine ethical aspects of the research process and to experience and understand the processes involved in team working.

Impact , innovation and outreach

My Saharan research has received significant media and public interest. In October 2009 aspects of my Saharan research featured in the National Geographic Magazine. The same year I was an advisor and contributor to a History Channel Television episode of the series 'How the Earth Was Made' that was dedicated to the Sahara and aired in December 2009. In 2010 I contributed to a National Geographic TV programme called the 'Worlds Oldest Child' that focused on the dispersal of early modern humans into North Africa, as well as advising on the Deserts -Life in a Furnace program of the BBC Human Planet series that aired on BBC 1 in 2011. In 2012-13 was involved in a BBC2/Discovery Channel series called 'Orbit: The Earth's Extraordinary Journey' where I advised on and contributed to the Saharan paleoclimate change aspects of the program.

The growing impact of this work has meant that during the last few years I have been invited to present my research to numerous UK and international conferences/workshops/meetings:
