Cancioneiro tradicional: questões de recolha e de classificação

Neste estudo, reflectimos sobre os critérios de recolha e de classificação do acervo de cancioneiro tradicional reunido por nós no concelho de Baião (distrito do Porto). Etapas fundamentais na constituição de um cancioneiro, são frequentemente sujeitas a erros que desvirtuam o produto final. Comentámos por isso os processos seguidos por alguns investigadores do folclore literário português, que, ao adoptarem metodologias desadequadas, deturparam a objectividade dos seus trabalhos. Com efeito, para além de incorrecções no sistema de classificação, vários autores alteraram a genuinidade de alguns originais, prejudicando assim a cientificidade da sua obra. Em relação à recolha, que comporta os registos escrito e electrónico (gravação sonora e audio-visual), a nossa experiência mostrou-nos que o próprio comportamento do intérprete e dos ouvintes, os comentários de agrado ou desaprovação e as correcções consideradas oportunas constituem valiosas informações para a compreensão do fenómeno poético oral.

Eco-touristic snorkelling routes at Marinha beach (Algarve): Environmental education and human impacts

The use of natural areas for underwater coastal marine activities such as snorkelling is growing, but the amount of ecological and socioeconomic data on these activities is scarce and relates mainly to coral reef areas. Three underwater self-guided routes were designed at Marinha Beach (Algarve, Portugal), based on scientific information, with in situ interpretation and guidance, as a way to enhance biodiversity awareness and, hence, reduce the probability of human impacts. The routes were implemented in two consecutive summer seasons and after each season, visual census techniques were used to describe flora composition and cover area (seaweeds and seagrasses) in order to understand patterns and evaluate human impacts. Snorkelers' opinions and perceptions about several issues related to the routes' environmental education role (e.g. role in enhancing biocliversity awareness) were investigated by questionnaire after the snorkelling activity. An inter-annual difference inflora assemblages was found, probably associated to natural variability, rather than snorkelers' impacts. Results indicate that, in fact, in situ education and interpretation can raise environmental awareness if properly addressed, resulting in a satisfactory way of engaging snorkelers in the protection and in the conservation of the visited environments, thereby preventing negative ecological impacts.
