Investigating the global stakeholder engagement process that informed the development of the Key Biodiversity Area Standard

Maxwell, Jessica Lynch January 2017 (has links)
This thesis investigated the development of the Global Standard for the Identification of Key Biodiversity Areas (KBA Standard), which is a new approach to identifying important sites for biodiversity. Key Biodiversity Areas are defined as sites contributing significantly to the global persistence of biodiversity. The KBA Standard was developed through a global stakeholder engagement process convened by the International Union for Conservation of Nature’s Joint Task Force on Biodiversity and Protected Areas (IUCN Task Force). The engagement process included four main components: (i) technical workshops with subject experts; (ii) interviews and an online questionnaire with end-users; (iii) regional events with additional interested stakeholders; and (iv) an open online consultation where stakeholders were invited to review the draft KBA Standard. The aim of this thesis was to use an action research approach to work with the IUCN Task Force to analyse the end-user component of the global stakeholder engagement process. End-users were defined during the engagement process as those who lead or influence decision-making processes linked to mechanisms that secure biodiversity or that avoid biodiversity loss. The main objectives of this research were to: (i) clarify the purpose of engaging end-users by examining the use of normative, instrumental, and substantive rationales; (ii) use mixed methods to gain an understanding of end-users’ needs and concerns; (iii) categorise and analyse end-users’ needs and concerns by sector and region; (iv) assess the end-user engagement process through a summative evaluation; (v) examine how end-user input was used to inform the development of the KBA Standard; and (vi) develop a set of recommendations related to global end-user engagement practice. The analysis indicated that the IUCN Task Force used a blend of instrumental and substantive rationales to justify engaging end-users. Five main categories of end-user needs and concerns emerged from the analysis of the qualitative interview data: (i) the need for communication and local stakeholder engagement; (ii) the potential for the KBA Standard to either complement or conflict with existing approaches; (iii) the need for clarity regarding the scale at which KBAs can be identified (i.e. global, regional, and/or national); (iv) concerns about the implementation of the KBA Standard, including data availability, timeliness, and resources; and (v) comments about how KBAs inform decision-making, including management options, sustainable use, and prioritisation. These topics were examined in depth through the qualitative interviews and in breadth through the quantitative questionnaire. The results demonstrate a high level of convergence in opinion on many topics; however, four topics resulted in a divergence in opinion between end-users, including: (i) the scale at which KBAs are identified; (ii) the prioritisation of KBAs over other areas; (iii) whether KBA data should be made freely available; and (iv) whether development activities should be permitted in KBAs. These areas of divergence were analysed further by categorising end-user questionnaire responses by sector and region. The results have important implications for how end-users are identified, categorised, and engaged and highlight the complex and individual nature of end-users’ needs and concerns. The summative evaluation analysed the purpose, process, outputs, and outcomes against a typology of engagement and principles of good practice for international standard setting to reflect upon how end-users’ needs and concerns were integrated into the development of the KBA Standard. This indicated both the strengths and weaknesses of the engagement approaches used and informed the development of 11 recommendations to inform future similar processes. This thesis ultimately helps to bridge the gap between stakeholder engagement theory and practice and provides insight into the challenges and benefits of using a mixed methods action research approach to investigate a global stakeholder engagement process.

Critérios de alocação de áreas prioritárias para a conservação em terras privadas / Criteria for allocating priority areas to the conservation in private lands

Galati-Barbosa, Ana Carolina 17 September 2012 (has links)
A elaboração de metodologias de seleção de áreas para proteção em terras privadas é considerado importante arcabouço teórico para subsidiar os órgãos gestores na implantação desses espaços. A maioria das metodologias sugere grande aporte de dados primários o que encarece os custos. Nesse sentido, alguns autores (RANIERI, 2004; MOREIRA, 2011) têm trabalhado com a seleção de metodologias baseadas em dados físicos de relevo para geração de cenários e suas aplicabilidades na alocação de áreas para a conservação em propriedades privadas. Entretanto, em seus estudos a vegetação nativa foi considerada única, não avaliando as fitofisionomias que seriam ou não protegidas em cada metodologia. O objetivo deste trabalho foi preencher estas lacunas e avaliar a possibilidade da conservação equitativa das diferentes fitofisionomias presentes na área de estudo. Além disso, comparou-se este estudo aos propostos anteriormente a fim de subsidiar o tomador de decisão na escolha do melhor cenário de seleção de áreas prioritárias de conservação. Para tanto, manteve-se o município de São Carlos como espaço amostral. Os resultados obtidos foram elencados de acordo com potencialidades de ação e fragilidades ambientais, deixando para o tomador de decisão a escolha definitiva destas áreas. / The development of methods for selecting areas for protection on private lands is an important theoretical framework to support the management agencies in the implementation of these spaces. Most methodologies suggests a large input of primary data which adds to the cost. In this sense, some authors (RANIERI, 2004; SMITH, 2011) have worked with the selection of methodologies based on physical data relevant to generate scenarios and their applicability in the allocation of areas for conservation on private property. However, in their studies the native vegetation was considered unique, not evaluating the physiognomies or not that would be protected in each methodology. The objective of this study was to fill these gaps and assess the possibility of equitable conservation of different vegetation types present in the study area. In addition, this study compared to previously proposed in order to support the decision maker in choosing the best scenario for selection of priority areas for conservation. Therefore, it remained the city of São Carlos as sample space. The results were listed according to potential for environmental action and weaknesses, leaving the decision maker the final choice of these areas.

Estudo das variações nas assembleias de culicídeos (Diptera: Culicidae) nos diferentes estratos da vegetação e sua relação com hábitos alimentares / Study of the variations of the mosquitoes assemblages (Diptera: Culicidae) in different strata of the vegetation and its relation with eating habits

Evangelista, Eduardo 17 October 2018 (has links)
Estudo entomológico foi realizado nos limites extremos do município de São Paulo, que possuem cobertura vegetal significativa em forma de Unidades de Conservação representadas ao norte, pelo Parque Estadual da Cantareira (PEC), onde epizootias e casos humanos de febre amarela têm ocorrido nos últimos anos, e ao sul, pela Área de Proteção Ambiental (APA) Capivari Monos onde ocorrem casos assintomáticos de malária-bromélia. Mosquitos foram coletados no período de fevereiro de 2015 a abril de 2017, em sete ambientes com feições periurbana, intermediária e silvestre. Armadilhas CDC foram instaladas na copa e ao nível do solo, com objetivo de verificar a estratificação vertical das espécies de mosquitos. Aspiração e armadilha de Shannon complementaram as coletas de fêmeas ingurgitadas para verificação do comportamento alimentar por técnica de PCR. Nove oligonucleotídeos do citocromo B mitocondrial foram utilizados para este propósito. Riqueza, abundância, composição e equabilidade foram utilizados para verificar a diversidade dos ambientes. No total foram obtidos 10.070 espécimes de culicídeos adultos distribuídos em 95 espécies/categorias taxonômicas distribuídas em dezesseis gêneros. Na APA, foram identificadas 75 espécies/categorias taxonômicas e 7.472 espécimes e desse total 67% foram mais frequentes na copa. As espécies Culex (Culex) nigripalpus e Anopheles (Kerteszia) cruzii, ambas ocorrendo com maior frequência no estrato copa em todos os ambientes pesquisados. No PEC, 58 espécies/categorias taxonômicas e 2.598 espécimes foram coletados e 55% foi coletado no estrato solo. Wyeomyia (Prl.) confusa (solo), Culex (Mel.) vaxus (copa) e Limatus durhamii (solo) foram as mais abundantes. Com relação aos hábitos alimentares 386 amostras foram obtidas, Anopheles cruzii representou 70% (270), se alimentando principalmente em hospedeiro humano no estrato solo. A presença de culicídeos vetores evidenciam a alta importância epidemiológica dos ambientes estudados merecendo atenção das autoridades em saúde publica, dada a interação entre as espécies de mosquitos e suas fontes de repasto sanguíneo. / An entomological study was carried out in the extreme limits of the municipality of São Paulo, which have significant vegetation cover in the form of Conservation Units, represented in the north, by the State Park of the Cantareira (PEC), where epizootics and cases human of Yellow Fever have been occurred in the last years, and in the South by the Environmentally Protected Area Capivari Monos, where asymptomatic cases of malaria-bromelia have been occurred. Mosquitoes were collected from February 2015 to April 2017 in seven environments with peri-urban, intermediate and wild features. CDC Traps were installed in the canopy and at ground level, with the objective of verifying the vertical stratification of mosquito species. Aspiration and Shannon traps complemented the collection of engorged females to verify the feeding behavior by PCR technique. Nine mitochondrial cytochrome B oligonucleotides were used to this propose. Richness, abundance, composition and equability were used to verify the diversity of environments. In total, 10,070 adult culicidis were collected, comprising 95 species / taxonomic categories distributed in sixteen genera. At APA, there were 75 species / taxonomic species and 7,472 specimens and a total of 67% were more frequent in the canopy. The species Culex (Culex) nigripalpus and Anopheles (Kerteszia) cruzii, occurred more frequently and canopy stratum in all the environments surveyed. In the PEC, 58 species / taxonomic categories and 2,598 specimes were collected and 55% were collected in the ground strata. Wyeomyia (Prl.) confusa (ground), Culex (Mel.) vaxus (canopy) and Limatus durhamii (ground) were more abundant. Regarding the feeding habits, 386 samples were obtained, Anopheles cruzii represented 70% (270), feeding mainly on human host in the ground strata. The presence of vector culicids evidences the high epidemiological importance of the studied environments, deserving attention of the Public Health Authorities due to the presence and interaction of mosquito species and their sources of blood feeding.

Diversidade isoenzimática e morfológica de inhame (Dioscorea spp.) coletados em roças de agricultura tradicional do Vale do Ribeira - SP / Isoenzymatic and morphological diversity of yams (Dioscorea spp.) collected in swiddens of traditional agriculture of the Ribeira River Valley - SP

Bressan, Eduardo de Andrade 30 August 2005 (has links)
Os agricultores tradicionais da região sul do Estado de São Paulo têm se mostrado mantenedores de um grande repositório de diversidade genética e de conhecimento a respeito das peculiaridades de manejo desta diversidade. A cultura do inhame (Dioscorea spp.) é mantida e manejada nesta região em roças que empregam o sistema de coivara. Esta pesquisa teve como objetivos coletar etnovariedades de inhame nas roças/quintais dos agricultores tradicionais do Vale do Ribeira, visando manter um banco de conservação ex situ na Escola Superior de Agricultura “Luiz de Queiroz" em Piracicaba – SP e estimar a diversidade morfológica e isoenzimática de inhames mantidos em sistemas agrícolas autóctones. Visitou-se 91 agricultores que ainda praticam a agricultura tradicional no Vale do Ribeira dos quais 45 cultivavam o inhame. Desses, 31% o cultivavam em roças itinerantes e 69% em quintais. Quatro espécies de inhame foram encontradas: D. trifida, D. bulbifera, D. alata e D. cayenensis. As etnovariedades foram caracterizadas por meio de marcadores isoenzimáticos, utilizando géis de poliacrilamida (seis sistemas) e amido (um sistema), e por marcadores morfológicos, num total de 24 caracteres. Para ambos os marcadores, foram calculados o índice de similaridade de Jaccard entre pares de indivíduos. Análises de agrupamento foram realizadas para variedades, roças e comunidades, a partir dos índices de similaridade de Jaccard e do critério aglomerativo UPGMA. Outro parâmetro analisado foi a correlação entre as matrizes de distância genética (isoenzimática e morfológica) e geográfica pela correlação de Pearson (r) e teste de Mantel, para verificar se a diversidade genética encontrava-se estruturada no espaço. Além disso, realizou-se a análise de variância molecular (AMOVA) para se verificar a distribuição da variabilidade nos diferentes níveis hierárquicos: entre e dentro das unidades evolutivas biológicas (roças) e culturais (comunidades). Os resultados revelaram que os agricultores tradicionais do Vale do Ribeira manejam grande diversidade genética, tanto isoenzimática como morfológica, em suas roças e que essa diversidade não está estruturada no espaço para todas as espécies cultivadas. A AMOVA indicou que para as espécies D. trifida, D. bulbifera e D. cayenensis a distribuição da variabilidade concentra-se entre roças dentro de comunidades, enquanto que para D. alata concentra-se dentro de roças para os marcadores isoenzimáticos. Para os marcadores morfológicos, a maior parte da variabilidade concentra-se entre roças dentro de comunidades para D. bulbifera e D. cayenensis e dentro de roças para D. alata e D. trifida, ressaltando-se a seleção humana para os aspectos visuais. Conclui-se que os agricultores tradicionais do Vale do Ribeira cultivam grande diversidade de etnovariedades e espécies de Dioscorea, além de possuírem grande conhecimento a respeito das peculiaridades de manejo desta cultura. Contudo, as pressões que esses agricultores estão sofrendo poderá no futuro provocar perda de diversidade genética. Recomenda-se novos estudos na região para verificar os danos causados por essas pressões aos processos evolutivos presentes nas roças dos agricultores tradicionais do Vale do Ribeira. / Traditional agriculturists of the south region of the State of São Paulo have been maintainers of a great repository of genetic diversity and knowledge regarding the management peculiarities of this diversity. The yam (Dioscorea spp.) culture is maintained and cultivated in this region in swiddens that use the system of “coivara". This research had the objective of collecting ethnovarieties of yam in the swiddens/home gardens of the traditional agriculturists of the Ribeira River Valley, aiming at maintaining a germplasm bank for ex situ conservation at the Escola Superior de Agricultura "Luiz de Queiroz" in Piracicaba, SP and estimating the morphological and isoenzymatic diversity of yams kept in authoctone agricultural systems. Ninety-one agriculturists that still practice traditional agriculture were visited in the Ribeira River Valley, of which 45 cultivated yam. Of these, 31% cultivated this crop on itinerant swiddens and 69% in home gardens. Four yam species were found: D. trifida, D. bulbifera, D. cayenensis and D. alata. The ethnovarieties of each species were characterized with isoenzymatic markers, using polyacrilamide gels (six systems) and starch gels (one system), and with morphological markers, in a total of 24 characters. For both markers, the Jaccard similarity indices between pairs of individuals were obtained. Cluster analyses were conducted for varieties, swiddens and communities using the Jaccard similarity indices and the UPGMA method. Another parameter analyzed was the correlation between the genetic distances (isoenzymatic and morphological) and the geographic distance matrices using the Pearson correlation and Mantel test, to verify if the genetic diversity was structured in space. An analysis of molecular variance (AMOVA) was carried out to verify the distribution of the variability in the different hierarchic levels: within and between the biological evolutionary units (swiddens) and cultural units (communities). Results showed that the traditional agriculturists of the Ribeira River Valley maintain a great genetic diversity, both isoenzymatic and morphological, in their swiddens and home gardens, and that this diversity is not structured in space for the four species cultivated. The AMOVA results for D. trifida, D. bulbifera and D. cayenensis showed that the isoenzymatic variability is mainly concentrated among swiddens within communities, and within swiddens for D. alata. For the morphological markers, where visual aspects are an important issue in human selection, most of the variability is concentrated among swiddens within communities for D. bulbifera and D. cayenensis, and within swiddens for D. alata and D. trifida. It is concluded that the traditional agriculturists of the Ribeira River Valley cultivate great diversity of ethnovarieties and species of Dioscorea, also possessing great knowledge concerning the management peculiarities of this crop. However, the pressures that these agriculturists are suffering may cause a loss of genetic diversity in the future. Further studies are recommended in this region to verity the damage caused by these pressures in the evolutionary processes that occur in the swiddens of the Ribeira River Valley traditional agriculturists.
