Across vast tracks of the world people are running short of a basic commodity: water. There are often many complex reasons that drive migration, but there is an undeniable relationship between water shortages and the large population movements we are seeing today.

For our fourth in a series of events in collaboration with the Scientific Exploration Society, we will be exploring how the effects of climate change are being seen across the Middle East and North Africa, the supply and control of water in the region, and the technologies that are being developed to combat the problem.

Chaired by the Guardian‘s environment editor, John Vidal.

The panel:

Roger Blench is a international development specialist and anthropologist. He has conducted research and evaluations of international development activities worldwide, notably in Nigeria and other regions of West Africa as a consultant and formerly as a research fellow of the Overseas Development Institute in London. He is now affiliated to the McDonald Institute of the University of Cambridge and is chief research officer for the Kay Williamson Educational Foundation.

Mikael Strandberg is a Swedish explorer and filmmaker. He has travelled solo through many parts of the world, including amongst communities in Yemen, through Africa and parts of Asia, and is currently working on a film project with migrants arriving to Sweden.

James Fergusson is an author and freelance journalist. He has written extensively on Afghanistan, Somalia and laterly used his degree in hydrology to write on water security in Yemen. His most recent book The Worlds Most Dangerous Place was nominated for the Orwell Prize.

Professor Tony Allan is based at King’s College London and SOAS London, he specialises in the analysis of water resources in semi-arid regions and on the role of global systems in ameliorating local and regional water deficits.

The panel will discuss how knowledge and understanding of environmental impact, extraction of resources and geopolitical issues have moulded the region, and what the consequences are for those of us watching from afar. With oil firm Royal Dutch Shell having recently won conditional approval from the US Department of Interior to explore for oil in the Arctic, we will be asking what this kind of exploration means for the region.

This event will be chaired by BBC Science editor David Shukman, whose reports on research have taken him as far afield as the Antarctic ice-sheet, the Amazon rainforest and the depths of the Gulf of Mexico. Since joining the BBC in 1983, he has covered Northern Ireland, defence, Europe and world affairs. He is author of An Iceberg As Big As Manhattan: Reporting from science’s new frontlines and Reporting Live from the End of the World.

Pen Hadow is an Arctic Ocean explorer and advocate. He is the founder and leader of the multi-award winning Catlin Arctic Survey (2007-2013), an international research programme on the Arctic Ocean, and the associated environmental research-sponsorship agency, Geo Mission. A decade on, Pen Hadow remains the only person to have reached the North Geographic Pole, solo and without resupply, from Canada.

Professor Martin Siegert FRSE is co-director of the Grantham Institute. Previously, he was director of the Bristol Glaciology Center at Bristol University and head of the School of GeoSciences at Edinburgh University. His particular field of expertise is to use geophysics to measure the subglacial landscape and understand what this tells us about changes to the environment. In 2013 he was awarded the Martha T. Muse Prize for excellence in Antarctic science and policy, and in 2007 he was elected as a fellow of the Royal Society of Edinburgh.

Charles Emmerson is a writer and historian based in London. He is the author of The Future History of the Arctic, exploring the past, present and future of our relationship with the Arctic, from past mythologies of the north to the modern emergence of the Arctic as a zone of geopolitical interest and massive environmental change.
