Technological innovations for achieving the SDGs
The World in 2050 (TWI2050), an international and institute wide crosscutting initiative, released its first report  at the 2018 High-level Political Forum at the UN Headquarters in New York through an invited plenary presentation and three side events. The report synthesizes a holistic perspective on strategies to address all 17 SDGs in an integrated manner and on an ambitious time schedule. TWI2050 concluded that six major transformations (Figure 1) are needed to realize a holistic SDG implementation strategy in the fields of human capacity and demography; consumption and production; decarbonization and energy; food, biosphere, and water; smart cities; and the digital revolution. Research by the IIASA Transitions to New Technologies Program underpinned two of these transformations, namely consumption and production , and the digital revolution.
A key entry point for an integrated strategy towards the achievement of the SDGs is to view consumption and production systems in an integrative fashion, avoiding any undue isolated supply- or demand side perspectives. Research into the current systems efficiencies of resource processing systems revealed that for energy, food, water, and materials, transformation and utilization efficiencies invariably become smaller the closer the systems boundaries are extended towards final service use. A service provision focus is therefore essential for addressing the SDGs, as services provide for human welfare, whereas corresponding upstream resources, while necessary, imply multiple environmental impacts. With water embedded in food, for example, an increase in the efficiency of nutrition for human sustenance through, for instance, a reduction in food waste, translates into a six-fold leverage effect on reducing water withdrawn for input to the food supply chain (Figure 2). The effects in other resources like materials or energy in Figure 2, are of comparable magnitude, highlighting a critical entry point for SDG policies, namely a focus on efficient service provision and associated innovations in technologies, practices, behaviors, and market organization.
Researchers also empirically explored the interlinkages and synergies between transformations through digitalization, and consumption and production by looking at the resource implications (materials and energy) of digital device and service convergence . Further critical interlinkages between the digital revolution and the other five transformations for the SDGs are being explored in more detail and will contribute to the TWI2050 report in 2019.
In addition to the above, researchers developed a rigorous analytical format for assessing technological options and trends as input for scenario modeling and policy analysis, and conducted two test case studies on the energy-water nexus. The first study focused on water desalination, which is highly energy intensive , while the second took a demand side view on agricultural irrigation technologies.
New research in the domains of social interactions , behavioral spillovers , and formative phases  and processes in technology innovation [7, 8], among others, further supports the research on integrated SDG implementation strategies [9, 10, 11, 12, 13, 14] and explores novel policy options.
