Sediments of Tamarindo estuary and its tributaries were evaluated in order to determine the effect of anthropogenic activities of the surrounding communities. The evaluation relied on texture, total phosphorus, organic matter, and heavy metal (Pb, Cu, Ni and Cr) analyses. The study spanned four sampling campaigns between October 2007 and April 2008, including four climatic seasons: rainy season, rainy-dry transition, dry season and dryrainy transition. Five sampling points were selected at Tamarindo estuary and three additional sites were set at Matapalo, Lomas and Lajas rivers. Ontario Ministry of the Environment regulation was used to evaluate sediment quality. It was determined that theanthropogenic activities of the surrounding communities exert a negative impact over the sediment quality; the pollution effect caused by such activities was rated as lower effect.

A experiência na construção da governança ambiental em torno do Parque Nacional Tortuguero na Costa Rica é a questão principal deste artigo. A mesma será analisada a partir da implementação do Conselho Local de Tortuguero/Setor Oeste e das articulações de atores do Setor Costeiro, notadamente, onde há incidência maior de turismo. Estruturou-se este artigo com base em pesquisas qualitativas, a exemplo de coleta de informações da bibliografia especializada, de dados documentais, legais e também via entrevistas. Por meio de tais movimentos, identificou-se uma série de ações relacionadas à conservação do meio ambiente e do turismo, dentro de uma perspectiva sustentável. Entretanto, em que pese os avanços alcançados, constata-se ainda a necessidade de se empreender mais esforços por parte de todos os envolvidos, sobretudo do Estado e na sua interação com os demais atores, pois persistem problemas diversos que são, historicamente, são insustentáveis a pensar-se em manejo do meio ambiente.

One way to do a bibliometric study is to examine each of the records that make up a database, each record and extract key areas that may disclose relevant information about the use of the database and documents in the collection . This article shows how a reference database allows to obtain important data that can reach conclusions that in some cases surprising. For this study we used the following fields of Database Control Documentary Indigenous Nationalities of Costa Rica 1979-2003: author, place of publication, publisher, year, language and support. The database analyzed has two thousand records and was developed in the Winisis. Moreover, analysis of documents was made after processing of the data, which was to export records to Excel software Winisis. After this information extracted from their chosen fields and are held by their respective separate chart or graph to present the results obtained. Furthermore, we show the application of different methods to learn more about the scientific aspects as: the Price Index, the Index of Collaboration This contribution will, first, for (as) students in the course of the race Metric Studies of Library and Information Science, National University, demonstrate and practice what you learned in this area. They may also benefit the (as) professionals from different areas, such as anthropologists (as), sociologists (as), linguists and librarians (as), among others (as).

Esta ponencia se basa en el proyecto CENTRO DE CONOCIMIENTO PARA GRUPOS INDÍGENAS CENTROAMERICANOS (GEIC), coordinado por la Escuela de Bibliotecología, Documentación e Información (EBDI) de la Universidad Nacional de Costa Rica, (UNA), su objetivo es “proponer la construcción de espacios de información para la población indígena, a partir del proyecto CENTRO DE CONOCIMIENTO PARA GRUPOS INDÍGENAS CENTROAMERICANOS y con esta ponencia se pretende presentar las lecciones aprendidas durante 2003-2007, años de recolección y análisis de datos, de establecimiento de relaciones, de coordinar actividades y ejecutar acciones tendientes a garantizar el cumplimiento al derecho de acceso a la información de las poblaciones indígenas costarricenses.El objetivo de GEIC fue crear un Centro de Conocimiento sobre/de Grupos Étnicos Indígenas Centroamericanos que sirviera de eje central para la consolidación del desarrollo de procesos tendientes a fortalecer la temática y el desarrollo de los grupos étnicos indígenas centroamericanos.El proyecto inició en el 2003, pero al no contar con personal permanente, se interrumpe su proceso hasta enero de 2004, con el desarrollo de la primera etapa, que comprende implementar cinco objetivos en Costa Rica. En posteriores etapas se espera integrar a los demás países centroamericanos.La población indígena costarricense corresponde a 63,876 personas, representando el 1.6% de la población nacional; existen ocho grupos socioculturales indígenas distintos, Cabécares, Bribris, Ngäbe, Térrabas, Borucas, Huetares, Malekus y Chorotegas, habitan en 24 territorios y hablan en 6 idiomas indígenas. A ellos se deben sumar poblaciones indígenas migratorias como los Miskitos de Nicaragua y Ngäbes de Panamá que trabajan en la producción agrícola en distintas zonas del país. El Proyecto GEIC, buscó la ejecución de la propuesta de creación de una unidad de información especializada en asuntos indígenas, en Shiroles Talamanca, para esto se realizó una investigación diagnóstica en la zona, determinando los recursos disponibles: tecnológicos, humanos, económicos y educacionales. En la actualidad se está gestionando y buscando financiamiento en instituciones locales, nacionales, e internacionales para cubrir los costos, aspecto que resulta un poco difícil por la falta de valoración de la importancia de la información en las comunidades indígenas.Otra actividad paralela a ésta es la construcción de un portal disponible en la dirección: http://www.una.ac.cr/bibliotecología/proyectogeic, y que fue avalado por las comunidades indígenas, con la participación de los y las protagonistas. En esa oportunidad se les explicó cada sección del mismo y se les solicitó sus observaciones y comentarios al respecto para involucrarlos(as) y se sintieran apropiados(as) de la misma.
