The Organisation for Economic Co-operation and Development (OECD) estimates that by 2050 the world's population will have risen to 9 billion. Similarly, by then global food production is expected to increase by 60%, global energy consumption is projected to grow by 80% and global water demands are estimated to increase by 55%. Given these outlooks, the security of water, energy and food is becoming increasingly important on policy agendas worldwide.
Agriculture is the largest consumer of the world’s freshwater resources, and more than one quarter of the energy used globally is expended on food production and supply. On the other hand most of the energy mix requires water for functioning: 95 percent of world’s electricity generation would cease to exist in the absence of water, fossil fuel production and the growing practice of shale gas extraction – or ‘fracking’ are also highly water intensive, as it is biofuel production. The linkages between these domains require an integrated approach to ensuring water, energy and food security, and sustainable agriculture and energy production across the globe.
The 2030 Agenda, with its 17 Sustainable Development Goals, 169 targets and 232 indicators, is the blueprint to a more sustainable, fair and equitable world. It is the first global agreement that recognizes the interlinkages among the concerned sectors and suggests ways to address them.
The workshop aims to provide an overview of the state-of-the-art, gaps and advances on the water-food-energy research to the entire scientific community, but particularly to PhD students. What is the state of the art on the water-energy-food nexus at a global and local scale? What are the future perspectives on this matter? These are some of the questions to be addressed.
