RESUMO
Sustainability indicators have become essential tools to deal with compartmentalized resources planning and management in cities. The development of water, energy, and food nexus (WEF nexus) indicators is a prominent goal of current research, but the focus is mainly on economic issues and material flows. Attention to the local scale and context, social aspects, and the inclusion of non-academic actors is mostly lacking. To address these gaps, this paper reports and reflects on the co-creation of sustainability indicators related to the WEF nexus in the city of São Paulo, Brazil. With a transdisciplinary approach, non-academic actors were included in the different stages of the process using the Urban Living Lab methodology, to improve the usability of the produced indicators' set. The case of São Paulo concerned on-going actions in the peri-urban and rural areas of the city which seek to improve environmental protection by stimulating more sustainable forms of agriculture. Thirty-four indicators were developed through a sequence of interactive activities, such as workshops, meetings, and field trips. The presented process aims to strongly enhance usability by actively involving users from the start, connecting the nexus approach to previous knowledge and familiar frameworks, paying attention to the local scale and context, and to social aspects, and by anticipating future use in various ways.
RESUMO
The governance of the nexus between water, energy, and food (hereafter, 'the nexus') is permeated by complex interactions of knowledge at a science-policy-society interface. This paper starts from a literature review to find the main narratives that allow us to understand what is at stake in this interface. By thematically synthesising 19 select articles, we reached three layers of knowledge interaction: 'knowledge application', 'knowledge integration', and 'knowledge transformation'. To avoid misleading simplifications, we discussed the constraints on this debate and some pressures for what we consider as 'closing down' knowledge about the nexus. We then developed a conceptual framework based on the 'technologies of humility' proposed by Jasanoff (2003, 2007) to create opportunities to 'open up' the nexus approach. Finally, we illustrated the four pillars proposed by some studies to describe what we have termed 'nexus of humility': framing, vulnerability, distribution, and learning. These foci seek to enable a humbler appreciation on all sides of the persistent sources of uncertainty, divergence, and conditionality in sustainability governance. This framework also contributes towards necessary transformations of knowledge about nexus and its challenging implementation.
