The call for measuring synergies and trade-offs between water, energy, and food is increasing worldwide. This article presents the development and application of a country-level index that has been calculated for 181 nations using open databases. Following an assessment of 87 water-, energy-, and food-related indicators, 21 were selected to constitute the Water-Energy-Food (WEF) Nexus Index. In this article, the WEF Nexus Index is utilized to assess the Southern African Development Community, where it demonstrates that food security is an area of concern, while the potential for beneficially exploiting water resources and energy projects exists in several countries. Water for agriculture could be achieved through the drought-proofing of rainfed agriculture and systematic irrigation development, with energy as the critical enabler. Neither the composite indicator nor the WEF nexus approach is the panacea that will solve all the significant development or environmental challenges facing humanity. However, they could contribute to integrated resource management and policy-making and are complementary to the Sustainable Development Goals. In this study, the methodology set out by the Joint Research Centre's Competence Center on Composite Indicators and Scoreboards has been followed. A set of visualizations associated with the WEF Nexus Index have been compiled in an interactive website, namely www.wefnexusindex.org.
Open innovation is proved to be determinant in the rationalization of sustainable innovation ecosystems. Firms, universities, governments, user communities and the overall environment are called to contribute to this dynamic process. This study aims to contribute to a better understanding of the impact of open innovation on firms’ performance and to empirically assess whether university-industry collaborations are complementary or substitutes for this activity. Primary data were collected from a survey encompassing 908 firms, and then combined with performance indicators from SABI (Spanish and Portuguese business information). Econometric estimations were run to evaluate the role of open innovation and university-industry collaboration in the firm innovative propensity and performance. Results highlight the importance of diversity in collaborations with the academia and inbound open innovation strategy as enhancers of firm performance. The two activities reinforce each other. By testing the impact of open innovation practices on company performance, the need for heterogeneity in terms of contact type and university is also demonstrated. Findings cast light on the need to reformulate existing policy packages, reinforcing the ties with academia as well as the promotion of open innovation strategies. The connection to the innovation ecosystem needs to be further encouraged as well as the promotion of persistent connections with the knowledge sources in an open and multilateral framework.
The Water-Energy-Food (WEF) nexus has, in the past decade, gained prominence as an approach for assessing integrated resource management. One challenge related to the WEF nexus approach is how to represent and monitor it since a system that includes water-, energy- and food-related parameters is complex. Not only are these resources quantified utilising different units, but they vary both spatially and temporally.This paper presents a national-level composite indicator that has been established for 170 countries, utilising the methodology developed by the Joint Research Centre: Competence Centre on Composite Indicators and Scoreboards. Following an assessment of 87 globally applicable water-, energy- and food-related indicators, 21 were selected to constitute the WEF Nexus Index. This index is made up of three equally weighted pillars representing the three constituent resource sectors, and six sub-pillars. A core element in the development of this index is equitable access to resources, which is characterised by each resource sector's ‘access’ sub-pillar. The WEF Nexus Index provides a quantitative perspective and offers a lens for evaluating trade-offs to be considered in the pursuit of sustainable development. To this end, it is intended for assessing national progress relating to integrated resource management as well as supporting decision making and policy development. The relevance and usefulness of the outcomes are demonstrated through an assessment of South Africa. The development of the WEF Nexus Index has demonstrated that no country is undertaking integrated resource management flawlessly. Every nation has the potential for improvement; which is evidenced by, for example, the top-ranking country for the index needing to reduce CO2 emissions. Neither the composite indicator nor the WEF nexus approach is, however, the panacea that will solve all the significant development or environmental challenges facing the global society. It can, however, contribute to integrated resource management and is complementary to the Sustainable Development Goals. It should ideally be utilised as an entry point into the underlying pillars, sub-pillars and indicators, in parallel with other qualitative and quantitative studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
