Visualising Values in the Caribbean: A Creative Approach to Value Assessment

In this article, a creative heritage value assessment that was developed on the island of St Christopher (St Kitts), West Indies is discussed and evaluated. A synergetic approach emerged out of a collaboration between local heritage managers and policy officials with foreign heritage researchers and archaeologists. Together, they developed a transdisciplinary and practice-oriented approach based upon capturing values with audiovisual methods, which effectively integrated archaeological-historical research as well as outreach and dissemination activities in the value-assessment process. This effectively brought valorisation as well as the contested and multivocal nature of heritage to the heart of a transparent heritage management process. The practicalities and rationale of this approach are discussed, as well as its potential benefits for the combined three fields of local heritage management, archaeological-historical research, and public outreach.     

Contesting the ‘greening’ of hydropower in the Brazilian Amazon

The 21st century has witnessed a resurgence of hydropower projects across the globe, with the energy source an integral part of contemporary sustainable energy transitions. Yet, the environmentalist credentials of hydropower remain contested by anti-dam movements. This paper details the cases of the Belo Monte and São Luiz do Tapajós dams in the Brazilian Amazon to explore how the development, submission and acceptance of an Environmental Impact Assessment provides a key site in the contestation of hydroelectric projects. Whilst the provision of this document – and the wider environmental licensing process – represents a key component in the asserted ‘green-ness’ of hydropower, opposition groups extend the scope of analysis to include indirect and cumulative impacts that remain understudied in official assessments. This paper analyses interviews and questionnaires with and documents provided by national and international civil society organisations to trace this process of challenge and critique. It details how civil society actors forward alternative assessments of the impacts of the projects studied, uncovering and illuminating overlooked and understudied externalities of hydropower in the Brazilian Amazon. An analysis of this process not only demonstrates that the ‘green’ credentials of hydropower remain far from assured but also highlights how anti-dam actors advance new ‘sustainabilities’ to discredit the terrain upon which such credentials are set.     

Earthquake Protection of Colonial Bell Towers in Colima,Mexico with Externally Prestressed FRPs

A methodology for the seismic vulnerability reduction of old masonry towers with external prestressing is presented. It is applied at the Colonial bell-towers of the Cathedral of Colima, Mexico, characterized for being a high seismic area (M>7.5). The 3D FE models are calibrated with experimental data and assessed through nonlinear static approaches including the seismic demand and an accurate validated masonry model. Based on an extensive parametric study on different configurations of old masonry towers, it is selected an optimal prestressing force and device. The Colonial towers are retrofitted with four prestressing devices of FRPs to convert them into a high energy-dissipative reinforced masonry. The external vertical prestressing is included at key points identified in the seismic vulnerability assessment. This technique is in compliance with the demand for architectural conservation and may be located without drilling and unbounded in order to be fully removable. The seismic performance is enhanced by increasing force, displacement, and internal confinement. It is observed an upgrading of 35% and 20% of displacement capacity. With these results it is corroborated that external vertical prestressing allows a substantial increment of ductility for seismic energy dissipation purposes.     

An Activity-Based Learning Approach for Key Geographical Information Systems (GIS) Concepts

This study presents the effect of active learning methods of concepts in geographical information systems where students participated in a series of interlocked learning experiences. These activities spanned several teaching weeks and involved the creation of a hand drawn map that was scanned and geo-referenced with locations' coordinates derived from virtual earth systems. These activities engaged students' attention, and the completion of the activities provided opportunities for formative feedback and summative assessments. The effect of the group of activities on students' learning was quantified through the collection of summative assessment data which was compared to performance in other assessment tasks.     

A post COVID-19 future - tourism re-imagined and re-enabled

Abstract

The urgent demands of the present necessitate an interrogation – a re-exploration and a re-envisioning of the future of tourism – of what has to change (and remain constant). Despite the crippling effects of COVID-19, new forms of solidarity are emerging that challenge the prevailing competitiveness ethic. While a transactional economic revival has to remain a top priority, progress will advance, so long as tourism becomes more transformational and transcendent. Discoveries of new methodologies for achieving the Sustainable Development Goals and versions of a Green New Deal, for example, are generating interest, notably ‘mass flourishing’ introduced in ‘anti-fragile’ ways. Utilizing a ‘future-back’ paradigm that demands deep-dive assessments and articulation of purpose, the gaps between ‘what is’ and ‘what could or should be’ are bound to close. Such undertakings represent a ‘coming together’ of all stakeholders, a role that academicians are urged to embrace, especially through action research, curriculum change and creation of ‘daring classrooms’.
