For Blake, the realisation that a Systems Thinking approach was fundamental came through his work on soil erosion in East Africa. There, soil is washed off the land into rivers, resulting in sedimentation and pollution. Erosion affects not just food production (millions of hectares of arable land and grazing areas are lost) but also water quality and even energy because of disruption to hydropower plants.
鈥淲e came up with all the evidence but when people asked 鈥楬ow are we going to change this?鈥 I realised I鈥檇 been looking at it through a single lens,鈥 he says. 鈥淥nly when I began working with social scientists did I appreciate the true complexity of the problem. For example, 鈥榦vergrazing鈥 was not a cause but a symptom of wider socioeconomic and cultural pressures.
鈥淯sing a process of co-design brought us tangible solutions and Systems Thinking became a very intuitive process.鈥
Systems Thinking is also influencing policy in Britain at governmental level, and we are now seeing positions such as the Head of Systems in Defra 鈥 incidentally taken by a former student of Thompson鈥檚. Blake and Thompson are keen to encourage collaboration and instil in students an appreciation that will inform their field work.
鈥淚t鈥檚 about changing the way students approach complex problems,鈥 says Blake. 鈥淎 key aspect for me is the interdisciplinarity,鈥 adds Thompson. 鈥淚t鈥檚 not dumbing down specialisms, it鈥檚 about connecting them. Our faculties have areas of disciplinary excellence and the institutes are a melting pot for those ideas and knowledge.鈥
Building on substantial funding success in environmental research, several more applications that are out for projects will bring together academics from across the University, including medicine and the arts, to tackle a range of challenges.
The Song of the Sea project, launching during COP26, attempts to explain the complexity of cause and effect on the ocean through a piece of data-inspired music created by experts at the University. It takes the notes of the old sea shanty Drunken Sailor and distorts them using digital signals from the February 2014 storm that battered the South West.
鈥淲e are illustrating climate change as a large storm event. Choosing Drunken Sailor is a way of suggesting humanity鈥檚 overindulgence,鈥 says Thompson. 鈥淚 see the arts as absolutely fundamental to how we visualise and explain problems to an audience who wouldn鈥檛 engage with a scientific paper. It鈥檚 another example of the way that Systems Thinking is needed. For me, it is a key direction of travel, not just for the University but for the planet.鈥
