Managing protected areas implies dealing with complex social-ecological systems where multiple dimensions (social, institutional, economic and ecological) interact over time for the delivery of ecosystem services. Uni-dimensional and top-down management approaches have been unable to capture this complexity. Instead, new integrated approaches that acknowledge the diversity of social actors in the decision making process are required. In this paper we put forward a novel participatory assessment approach which integrates multiple methodologies to reflect different value articulating institutions in the case of a Natura 2000 network site in the Basque Country. It integrates within a social multi-criteria evaluation framework, both the economic values of ecosystem services through a choice experiment model and ecological values by means of a spatial bio-geographic assessment. By capturing confronting social and institutional conflicts in protected areas the participatory integrated assessment approach presented here can help decision makers for better planning and managing Natura 2000 sites.

In recent years, participatory approaches have been incorporated in decision-making processes as a way to strengthen the bonds between diverse areas of knowledge and social actors in natural resources management and environmental governance. Despite the favourable context, this paradigm shift is still in an early stage within the development of the Natura 2000 in the European Union, the largest network of protected areas in the world. To enhance the full scope of participatory approaches in this context, this article: (i) briefly reviews the role of participatory approaches in environmental governance, (ii) develops a common framework to evaluate such participatory processes in protected area management, (iii) applies this framework to a real case study, and (iv) based on the lessons learned, provides guidance to improve the future governance of Natura 2000 sites.

This report represents the key output of a training workshop hosted by Lake Victoria Fisheries Research Project (LVFRP) for researchers from each of the riparian countries fisheries research institutes. The workshop aimed to train the researchers in participatory research techniques which they could use to undertake a study of community-based institutions and organizations which could potentially be involved in fisheries co-management. A central focus of the workshop was a study to identify the community-based organizations and institutions, which operated at Kiumba beach, and this study is reported here. Separate reports, which include operated at Kiumba beach and this study is reported here. Separate reports, which include details of the training process and the participatory methods used, are available (Sarch 1995, 2000). The report centers on the information generated from the participatory pilot study conducted by the workshop participants and the community at Kiumba Beach over the course of a week in March 2000. Ranges of participatory research techniques were used and the discussion and diagrams, which resulted from them, form the basis of this report. The workshop participants undertook a preliminary analysis of these findings and this has been synthesized at the end of this report. (PDF contains 55 pages)

O objetivo deste trabalho é determinar o tempo decorrido e fatores relacionados a sobrevida, a partir do diagnóstico da AIDS dos pacientes atendidos no Centro de Pesquisa Hospital Evandro Chagas (CPqHEC). Comparar a sobrevida segundo os critérios definição de caso de AIDS estabelecidos pelo Centro de controle de doenças e prevenção dos EUA (CDC) em 1987 e 1993 e pelo Ministério da Saúde Brasil em 1998. De um total de 1591 indivíduos com sorologia positiva para HIV, cadastrados entre 1986 a 1999, foi selecionada uma amostra aleatória sistemática com 392 indivíduos, sendo identificados 193 casos de AIDS pelo critério CDC 1993. A sobrevida foi considerada como o tempo decorrido da data do diagnóstico da AIDS ao óbito (falha), sendo a censura definida para os pacientes com perda de seguimento ou que permaneceram vivos até dezembro de 2000, com a data da censura igual a data do último atendimento. A duração da sobrevida foi descrita através do método de Kaplan-Meier, sendo comparadas as funções de sobrevida das categorias das variáveis pelo teste log-rank. Um modelo com os co-fatores de maior relevância na sobrevida foi ajustado, utilizando-se o modelo dos riscos proporcionais de Cox. Dos 193 pacientes com AIDS, 92 (47,7%) morreram, 21 (10,9%) abandonaram o tratamento, e 80 (41,7%) permaneceram vivos até o fim do estudo. Encontramos sobrevida relativamente alta nos três critérios de definição de caso avaliados, em parte explicada pelos casos serem procedentes de um único hospital de pesquisa, com alto grau de conhecimento na condução da doença. A profilaxia primária para PPC foi preditor de melhor sobrevida. Casos com AIDS definida por herpes zoster apresentaram melhor prognóstico e os definidos por duas doenças o pior prognóstico.

Ihale is a large landing site lying approximately 65 km. from Mwanza along the main Mwanza-Musoma highway. Ihale Beach was selected as a potential candidate for the 3-beaches study because of its proximity to Mwanza, and hence suitability for frequent monitoring; and because it is served by a road accessible during the rainy seasons. As with the first training Participatory Rural Appraisal (PRA) on Kiumba Beach on Kenya's Rusinga Island, the objectives with this PRA were as follows: (a) To identify and understand Ihale's community-based organizations and institutions which have a role in the lake's fishery. (b) To consider the key issues which arise from this study for the involvement of communities and community-based organizations and/or institutions such as those at Ihale Beach, in the co-management of Lake Victoria's fishery.

This document contains the findings of the second Participatory Rural Appraisal (PRA) carried out under the LVFRP. Its principal objectives were to develop base-line information on a Ugandan beach for the 3-beaches survey of the LVFRP.
