RESUMO

Introducción: Los pescadores en Playas del Coco, Guanacaste, Costa Rica, son vulnerables por el mal manejo y gestión de los recursos pesqueros y la pesca ilegal, excluyéndose de los beneficios otorgados por el Estado. Esto incide en que no cuenten con opciones que les permita crecer tanto a nivel económico como social. Objetivo: Determinar una estrategia de promoción social para las personas en exclusión social de Playas del Coco. Métodos: De febrero a septiembre 2018, se aplicó la Acción Participativa y la investigación Crítica, por medio de la entrevista semi estructurada y abierta, y la observación participante a miembros de la Asociación de Desarrollo, líderes comunales y pescadores de la zona, con edades entre los 17 y 40 años. Resultados: Se establecieron las bases teórico prácticas para un trabajo interdisciplinario entre trabajo social, turismo y biología marina por medio de la estrategia de intervención para los pescadores artesanales de Playas del Coco basada en el Modelo Socioeducativo Promocional y se documentó la situación actual de los habitantes de esta región. Conclusiones: La incursión del trabajo social en temas ambientales es viable, promocionando socialmente a los habitantes de Playas del Coco usando el turismo marino sostenible a través del modelo socioeducativo promocional.


Introduction: Fishermen in Playas del Coco, Guanacaste, Costa Rica, are vulnerable due to the mismanagement of fishing resources and illegal fishing; excluding them from benefits granted by the State. This means that they do not have many options that allow them to grow both economically and socially. Objective: Determine a social promotion strategy for people in social exclusion in Playas del Coco. Methods: From February to September 2018, participatory action and critical research were applied, through semi-structured and open interview, and participant observation to members of the Development Association, community leaders and fishermen in the area, ranging in age between 17 and 40 years old. Results: Theoretical and practical bases were established for an interdisciplinary work between social work, tourism and marine biology through the intervention strategy for fishermen of Playas del Coco based on the Socio-educational Promotional Model and the current situation of the inhabitants was documented. Conclusions: The incursion of social science in environmental issues is viable, by social promotion of the inhabitants of Playas del Coco developing sustainable marine tourism through a socio-educational model.

RESUMO

In order to survive in a highly competitive environment, freshwater or marine algae have to develop defense strategies that result in a tremendous diversity of compounds from different metabolic pathways. Recent trends in drug research from natural sources have shown that algae are promising organisms to furnish novel biochemically active compounds. The current review describes the main substances biosynthesized by algae with potential economic impact in food science, pharmaceutical industry and public health. Emphasis is given to fatty acids, steroids, carotenoids, polysaccharides, lectins, mycosporine-like amino acids, halogenated compounds, polyketides and toxins.
