Darlith Gyhoeddus: Geology and the food-water-energy nexus in developing countries

Yr Athro Mike Stephenson, Cyfarwyddwr Gwyddoniaeth a Thechnoleg, Arolwg Daearegol Prydain

"In this lecture, Prof. Mike Stephenson, Director of Science & Technology at the British Geological Survey, will discuss how population growth, urbanisation and climate change combine to create challenges for the food-water-energy nexus in the developing world. This challenge has a geological aspect in that solutions often involve the use and management of subsurface resources. In East Africa, for example, the people of Ethiopia, Kenya, Uganda, Tanzania and Mozambique are already affected by poverty and food insecurity worsened by erratic rainfall and crop yields. About 90% of subsistence food production in the region comes from rain fed agriculture, and the vulnerability of soil increases with increasing climate variability and long-term climate change. The total population of the region was 286 million in 2012, and will be 800 million by 2060 and 1150 million by 2090, so energy demand will rise enormously.

Prof. Stephenson will consider some geological aspects of the food-water-energy nexus in the developing world, paying particular attention to East Africa. Research on topics such as soil sustainability under climate change, identifying selenium soil deficiency risks and quantitative mapping of groundwater resources all play a part. Perhaps most interesting is the energy dilemma in Africa. The latest forecasts show that demand for fossil fuels will grow in Africa and the developing world. Will the developing world undergo a ‘fossil revolution’ like the developed world’s industrial revolution, or will it leap-frog fossil fuels to renewables, like it did landline telephones? Whatever happens, the way developing countries generate their future energy will have an influence on global attempts to keep emissions under a ‘two-degree limit’."

Mae'r Athro Mike Stephenson yn Gyfarwyddwr Gwyddoniaeth a Thechnoleg Arolwg Daearegol Prydain. Mae wedi gwneud gwaith ymchwil yn y Dwyrain Canol ac Asia, gan gynnwys gwaith pwysig dros ben yn Oman, Saudi Arabia, Jordan, Pacistan, Iran ac Irac. Mae Mike hefyd yn rhedeg Rhaglen Gwyddoniaeth yr Arolwg,  canolfan geowyddoniaeth a data cenedlaethol y DU, lle mae’n gyfrifol am 520 o wyddonwyr a thechnolegwyr.  Mae ganddo gadeiriau athro ym Mhrifysgolion Caerlŷr a Nottingham. Mae ei lyfr a gyhoeddwyd yn ddiweddar ‘Shale gas and fracking: the science behind the controversy’ wedi cael  'sylw anrhydeddus' yng Ngwobrau PROSE yr Association of American Publishers yn Washington DC. Mae Mike Stephenson yn cynrychioli buddiannau gwyddoniaeth y DU ym maes ynni yn rheolaidd, yn ogystal â rhoi cyngor helaeth i Lywodraeth y DU. Er enghraifft, ym mis Hydref 2013 bu’n cynghori  Syr Mark Walport, Prif Gynghorydd Gwyddonol Llywodraeth y DU, ar daith canfod ffeithiau i Texas a Alberta, ynghylch dal a storio nwy siâl a charbon.
