TMG’s Urban Food Futures programme closes its scoping phase with a series of reports summarising the main insights lying the foundation for the next phase of action research. Grounded in the right to food and the six dimensions of food security, this working paper explores how community kitchens, school feeding programmes, and informal saving schemes work and how communities use them to cope with shocks. The paper investigates how vulnerable urban communities in Ouagadougou, Nairobi, and Cape Town use these three components to combat hunger and food insecurity in times of crises such as the Covid-19 pandemic, violent evictions, and armed conflicts. The paper further explores both the potential and the barriers of these initiatives to become urban nutrition hubs, places where community members engage in dialogues and build social capital to understand the structural conditions of hunger and what they can do to address them.

TMG’s Urban Food Futures programme closes its scoping phase with a series of reports summarising the main insights lying the foundation for the next phase of action research. This working paper, written in collaboration with partners African Centre for Cities (ACC), FACT and Muungano AMT, argues that for the progressive realization of the right to food in urban settings, food sensitive planning and urban design must be integrated into urban governance actions. Findings from Ouagadougou, Nairobi, and Cape Town indicate the necessary steps that need to be taken toward more food-sensitive planning: clearly defining the mandate to govern urban food systems by national and local governments; drawing from community knowledge and experience for strategic thinking around food systems, and politicising urban food system issues to create the momentum needed in holding relevant authorities accountable.

Authors: Díaz-Arce Dariel , Loyola-Illescas Efraín
Published: October 2022

Digital competences are increasingly making their way as essential to achieve a true information and knowledge society. Identifying, describing and evaluating them are vital processes to differentiate them from other skills necessary for working with ICT. These competences are an important need in the current context of COVID 19, both due to their deficiencies in the general population and in the educational field. In this review of the literature, the differences of this concept with others such as information literacy and digital literacy are observed, both from their areas of study, to the dimensions and standards for their implementation and evaluation. Evidence is provided of the importance of the digital divide to achieve them, and of how they can be developed from different strategies such as the Inverted Classroom. The results suggest that this methodology could be suitable in the context of current education.

Software-defined network technology for learning in research and education groups
Authors: Silva José
Published: October 2022

Software Defined Network (SDN) is an emerging and programmable network paradigm that changes the way networks are designed and managed by introducing an abstraction that decouples control from the data plane. This technology has generated great interest in both industry and academia. SDN aims to simplify network management while allowing students, teachers, and researchers to experiment with protocols on networks that are used on a daily basis. In addition, it has led to the emergence of new trends in educational systems, especially the university sector, in computer systems and network administration. Due to the little diffusion of the SDN and the high projection that this technology currently has, it is essential that the university educational entities are those that dabble in this issue. That is why this essay is a synthesis that addresses the importance of applying SDN for educational purposes and in the context of academic research groups.

“The invisible is not what does not exist, but what we cannot observe." The objective of this research is to determine the impact of the invisible learning of Moravec and Cobo (2011) on the acquisition of the English language. To this end, the available scientific literature was reviewed, proceeding later to argue the benefits of invisible learning in learning English with technological tools. The emergence of new technologies requires that teachers act in an innovative way by applying teaching strategies that facilitate the educational achievement of the student, developing social, reflective and cognitive skills. Said learning is no longer only conceived as the incorporation of new grammatical structures, but with the learning of a new culture. From the trial, it was possible to conclude that invisible learning shows a relevant role when learning a foreign language due to its characteristics that incorporate ICTs and gamification, which are highly accepted and motivating for students in the classroom.
