A framework for sustainable ecotourism : application to Costa Rica

Costa Rica is a small Central American nation that has gained an international reputation as a leader in environmental conservation. This has formed the base for its highly successful and lucrative small-scale ecotourism industry. However, there are threats from high rates of deforestation and expanding large-scale tourism that is trading on strong environmental credentials, so it is appropriate to conduct this policy analysis on such a significant ecotourism area. The paper develops an ecologically sustainable economic framework, drawing on the works of Adolph Lowe (1893-1995) and Michalstrok Kalecki (1899-1970), to examine the Costa Rican experience and then analyse lessons for general policy development of any ecotourism area. The analysis is conducted from a political economy (and not a tourism management) perspective on the trade-offs between small-scale and large-scale ecotourism.

Ecotourism in Costa Rica: an economic framework of analysis

Costa Rica is a small Central American nation that has gained an international reputation as a leader in environmental conservation. This has formed the base for its highly successful and lucrative small-scale ecotourism industry. However, there are threats from high rates of deforestation and expanding large scale tourism that is trading on strong environmental credentials. This paper sets out an ecologically sustainable economic framework to firstly examine the Costa Rican experience, and then analyse lessons for general policy development of any ecotourism industry. The analysis is conducted from a political economy perspective on the trade-offs between small-scale and large-scale tourism.

Controlling the philosophical imaginary: reading Pierre Hadot with Luiz Costa Lima

This essay proffers a critical complement to Luiz Costa Lima's claims concerning the nature, history, and control of the imagination in Western culture. Accepting the wide scope of Costa Lima's critical claim about the socio-political control of imaginative literature in Western history, we claim that Pierre Hadot's work on philosophy as a bios in the ancient West cautions us lest we position philosophy in this history as always and necessarily an agency of control. At different times, philosophy has rather stood as an ally in practicing and promoting forms of criticity, and the playful, creative, and transformative envisaging of alternative ways of experiencing the world Costa Lima theoretically celebrates in literary fiction. Any critique of philosophy as always opposed to the critical imagination can only stand, we have argued, relative to philosophy as conceived on what Hadot suggests is but one, albeit the now hegemonic model: namely, as a body of systematic rational discourses, including discourses about the literary, poetics, and imaginary. What this vision of philosophy misses, Hadot shows, is how the ancient conception of philosophy (which survives in figures like Montaigne, Nietzsche, and Goethe) as a way of life promoted distinctly literary, aesthetic, and imaginative practices; first, to assist in the existential internalisation of the schools' ideas; secondly, to envisage in the sage and utopias edifying counterfactuals to help students critically reimagine accepted norms; and thirdly, in the conception of a transformed way of living and perceiving ‘according to nature’, whose parameters of autonomy and pleasurable contemplation of the singularity of the present experiences anticipate the experiences delineated in modern aesthetic theory.

Granitic coastal geomorphology: Applying integrated terrestrial and bathymetric LiDAR with multibeam sonar to examine coastal landscape evolution

Coasts composed of resistant lithologies such as granite are generally highly resistant to erosion. They tend to evolve over multiple sea level cycles with highstands acting to remove subaerially weathered material. This often results in a landscape dominated by plunging cliffs with shore platforms rarely occurring. The long-term evolution of these landforms means that throughout the Quaternary these coasts have been variably exposed to different sea level elevations which means erosion may have been concentrated at different elevations from today. Investigations of the submarine landscape of granitic coasts have however been hindered by an inability to accurately image the nearshore morphology. Only with the advent of multibeam sonar and aerial laser surveying can topographic data now be seamlessly collected from above and below sea level. This study tests the utility of these techniques and finds that very accurate measurements can be made of the nearshore thereby allowing researchers to study the submarine profile with the same accuracy as the subaerial profile. From a combination of terrestrial and marine LiDAR data with multibeam sonar data, it is found that the morphology of granite domes is virtually unaffected by erosion at sea level. It appears that evolution of these landscapes on the coast is a very slow process with modern sea level acting only to remove subaerially weathered debris. The size and orientation of the joints determines the erosional potential of the granite. Where joints are densely spaced (<2 m apart) or the bedrock is highly weathered can semi-horizontal surfaces form.
