Agriculture is the principal source for satisfying the growing global demand for food. However, current production patterns and socioeconomic and demographic pressures could lead to an unsustainable, inequitable food supply. Government interventions support technical advances designed to meet future needs following international trends while overcoming biophysical constraints. Those most often used are focused on augmenting land productivity through mechanisation and increased dependence on external inputs. To that end, public policies have emerged as engines of development in agriculture and the agri-food system. This article provides a chronological analysis of the relevant milestones in the agri-food sector in Ecuador (1960–2020). At first, agrarian reform focused on land distribution and tenure. Subsequently, the focus moved to the implementation of research, technological innovation and technology transfer programmes promoted by the state with support and financing from international organisations. For this article, we chose for our approach the water–energy–food nexus. Until now, insufficient study based on this approach regarding agricultural programmes has been conducted in Ecuador. It is essential to concentrate on this sector because it represents about 10% of the gross domestic product and is a principal source of employment for more than two-thirds of the economically active population in rural areas. However, land fractioning, the lack of project continuity and the focus on the application of technological packages identified in this analysis suggest the need to rethink public policies for a sustainable agri-food system.

“…Alternatively, when review article publications are considered, the results illustrate an estimated growth rate of 476% (more than double the growth rate of research articles). In these reviews, scholars often use qualitative methods to examine WFE nexus' state of the art such as in(Fan et al, 2019) where the authors have discussed the nexus using urban metabolism framework, or in(Gai et al, 2022) where the authors deciphered the methodological aspect of WFE nexus related to political agendas, boundary level, and nexus dimension. However, learning from case studies per se to shape a transferable urban knowledge regarding WFE nexus is largely lacking.…”

Understanding how water, food, and energy interact in the form of the water-food-energy (WFE) nexus is essential for sustainable development which advocates enhancing human well-being and poverty reduction. Moreover, the application of the WFE nexus has seen diverse approaches to its implementation in cities across the globe. There is a need to optimize knowledge sharing to improve urban information exchange focused on the WFE nexus' application and impact on the UN Sustainable Development Goals. In this study, Natural language processing (NLP) and a nity propagation algorithm are employed to explore and assess the application of the WFE nexus on a regional basis as well as at city levels. The results show that after the exhaustive search of a database containing 32,736 case studies focusing on 2,233 cities, cities with the most potential to encounter resource shortages (i.e. WFE limitation) are systematically underrepresented in literature (African and Latin American cities). Hence, with regional and topic bias, there is a potential for more mutual learning links between cities that can increase WFE nexus policy exchange between Northern and Southern hemispheres through bottom-up case-study knowledge. In addition, this study shows that Southern hemisphere cities can bene t from knowledge transfer because of their limited urban intelligence programs.
