Integrated Livelihoods and Landscape Approach for Smallholders in Northern Thailand

This paper examines the strategies and techniques researched and implemented by the International Union for Conservation of Nature (IUCN) in villages in the vicinity of Doi Mae Salong in Chiang Rai Province, Thailand. The strategies revolve around the paradigm linking poverty alleviation, conservation and landscape restoration. IUCN and its partners specifically researched and implemented schemes directed toward diversification of the household economy through alternative and sustainable intensified agriculture techniques based on balancing conservation and livelihood objectives. The projects aimed to reduce poverty and build the resilience of smallholders through decentralised governance arrangements including land use planning schemes and stakeholder negotiation. Considering the agro-ecological system on a catchment-wide scale enhances the conceptual understanding of each component, collectively forming a landscape matrix with requisite benefits for biodiversity, smallholder livelihoods and ecosystem services. In particular, the role of enhancing ecosystem services and functions in building socio-ecological resilience to vulnerabilities such as climate and economic variability is paramount in the process.

Evaluating the Small Population Paradigm for Rare Large-Bodied Woodpeckers, with Implications for the Ivory-billed Woodpecker

Six large-bodied, ≥ 120 g, woodpecker species are listed as near-threatened to critically endangered by the International Union for Conservation of Nature (IUCN). The small population paradigm assumes that these populations are likely to become extinct without an increase in numbers, but the combined influences of initial population size and demographic rates, i.e., annual adult survival and fecundity, may drive population persistence for these species. We applied a stochastic, stage-based single-population model to available demographic rates for Dryocopus and Campephilus woodpeckers. In particular, we determined the change in predicted extinction rate, i.e., proportion of simulated populations that went extinct within 100 yr, to concomitant changes in six input parameters. To our knowledge, this is the first study to evaluate the combined importance of initial population size and demographic rates for the persistence of large-bodied woodpeckers. Under a worse-case scenario, the median time to extinction was 7 yr (range: 1–32). Across the combinations of other input values, increasing initial population size by one female induced, on average, 0.4%–3.2% (range: 0%–28%) reduction in extinction rate. Increasing initial population size from 5–30 resulted in extinction rates < 0.05 under limited conditions: (1) all input values were intermediate, or (2) Allee effect present and annual adult survival ≥ 0.8. Based on our model, these species can persist as rare, as few as five females, and thus difficult-to-detect, populations provided they maintain ≥ 1.1 recruited females annually per adult female and an annual adult survival rate ≥ 0.8. Athough a demographic-based population viability analysis (PVA) is useful to predict how extinction rate changes across scenarios for life-history attributes, the next step for modeling these populations should incorporate more easily acquired data on changes in patch occupancy to make predictions about patch colonization and extinction rates.

Conservação dos invertebrados em área de proteção ambiental litorânea no nordeste do Brasil: contribuições da educação ambiental para a sustentabilidade

Today's society is in a real collapse of an environmental nature. The populations are lost due to a dream of development without thinking of the consequences that said development can bring to human populations. Thus, it is necessary that strategies be developed for the purpose of protecting the flora and fauna that is at risk from suffering the pressure to achieve this development. Thus important issues involving the need to conserve nature and the creation of protected areas as these strategies are increasingly being developed in research, whether in the biological and / or social. In this sense, the aim of this research through environmental perception social actors for the formation of significant elements for understanding the relationship between man and nature, and from there to provide actions for sensitization. As well as changing attitudes towards environmental issues, to thereby provide analysis based on Environmental Education in order to provide the production of environmental knowledge as a tool that provides value shift. This area of research was to study the Environmental Protection Area Jenipabu - APA Jenipabu, located in northeastern Brazil. Where, from the environmental perception of students from schools within and around this Nature Conservation Unit notes were made regarding the value and meaning given by students, and how this, the feeling of belonging to these groups. This dissertation is composed of two chapters, the first is titled Environmental perception and feeling of belonging in the area of environmental protection in coastal RN - Brazil, where it makes a diagnosis of how these groups understands and realizes the Unity of Nature Conservation. The second, which is titled Construction of environmental knowledge and conservation of invertebrates in the Environmental Protection Area in the northeast coast of Brazil, specifically developed in the school from within the APA Jenipabu, in order to promote a sense of belonging for those students who become multipliers, in order to realize the importance and necessity of having this unit for Nature Conservation. Looking to the degree of importance of environmental education as a tool to raise awareness on conservation of invertebrates and is all the fauna and flora exists, whether in a conservation of nature or not

Tracking the fin trade: Genetic stock identification in western Atlantic scalloped hammerhead sharks Sphyrna lewini

Location or stock-specific landing data are necessary to improve management of shark stocks, especially those imperiled by overexploitation as a result of the international shark fin trade. In the current absence of catch monitoring directly at extraction sites, genetic stock identification of fins collected from major market supply chain endpoints offers an overlooked but potentially useful approach for tracing the fins back to their geographical, or stock of, origin. To demonstrate the feasibility of this approach, we used mitochondrial control region (mtCR) sequences to trace the broad geographical origin of 62 Hong Kong market-derived Sphyrna lewini fins. Of these fins 21% were derived from the western Atlantic, where this species is listed as 'Endangered' by the International Union for the Conservation of Nature (IUCN). We also show that S. lewini mtCR sequences are geographically segregated in the western Atlantic (overall ΦST = 0.74, n = 177 sharks), indicating that breeding females either remain close to, or home back to, their natal region for parturition. Mixed stock analysis simulations showed that it is possible to estimate the relative contributions of these mitochondrial stocks to fin mixtures in globally sourced trade hubs. These findings underscore the feasibility of using genetic stock identification to source market-derived shark fins to obtain essential and otherwise unavailable data on exploitation levels, and thus to productively inform stock assessment and management of S. lewini and potentially also of other fished shark species. © Inter-Research 2009.

Marine Protected Areas in Brazil: An ecological approach regarding the large marine ecosystems

The objective of this study was to address the importance of implementing Coastal and Marine Protected Areas in Brazil and to examine their distribution, based on the delimitation of Large Marine Ecosystems. Out of a total of 336 protected areas identified in Brazilian coastal and marine areas, the North Platform has the largest protected area, but the ecosystem with the largest number of protected area, predominantly sustainable areas, was the East Coast followed by the South Platform. One of the reasons the eastern coast of Brazil to have more protected areas is the fact that there is a largest amount of coral reefs. Additionally there was political opportunities for the creation of protected areas for sustainable use. The coastal region of Brazil has achieved the goal proposed by the Seventh Conference of the Parties to the Convention on Biological Diversity - 7, but only then through the category V of the International Union for Conservation of Nature, which is not the best efficient means of conserving resources. The goal for marine conservation shows only the area above the recommended under protection in North Platform. The Marine portion of the East Coast and the South Platform has few protected areas, regardless of category management. We consider the coastal region the range of 12 nautical miles from baselines determined in accordance with the United Nations Convention on the Law of the Sea. As for the number of strategies permitted by law and used for the conservation of coastal and marine systems, coastal systems show a higher number when compared with the marine system. We suggest that the Brazilian government should specify strategies for the protection of marine systems and expand the protected areas of all Large Marine Ecosystems. © 2013 Elsevier Ltd.

Conflitos socioambientais na gestão de Unidades de Conservação: o caso da Reserva Biológica do Lago Piratuba/AP

Conflitos sociais estão presentes em todas as relações da humanidade, destacando-se a partir da sociedade moderna e acirrou-se nas relações contemporâneas. Dentre os conflitos sociais, os envolvendo a utilização da natureza são os mais preocupantes, sobretudo, devido à escassez que os recursos naturais estão submetidos. O ambiente faz parte dos interesses difusos, isto é, os indivíduos gostariam que o ambiente fosse preservado, porém, são poucos os que adotam estes objetivos como preponderantes em suas atividades socioeconômicas. Esse comportamento aumenta as pressões sobre os recursos ambientais, inclusive nas áreas legalmente protegidas. Os conflitos socioambientais relacionados à gestão destas áreas estão presentes em todas as fases de sua instituição e ocorrem a partir das concepções teóricas e filosóficas das principais correntes que embasam a preservação e conservação da natureza. No Brasil é comum estabelecer unidades de conservação para solucionar as tensões entre a exploração dos recursos naturais e a sustentabilidade dos ecossistemas. Entretanto, o que ocorre, em geral, é a intensificação dos conflitos nas áreas constituídas. O Amapá se destaca no cenário nacional por ser um dos Estados que tem alto grau de preservação e percentual significativo de unidades de conservação. Porém, os conflitos entre os gestores e os usuários destas áreas são constantes e em vários casos intensos, o que provoca a degradação dos recursos naturais destes espaços e a desestruturação social das populações. As alternativas ortodoxas para solucionar os conflitos não se apresentam eficientes, sendo necessário adotar medidas como a negociação para amenizar ou resolver as tensões relacionadas à sustentabilidade dos recursos ambientais e sociais. Como apoio a negociação a literatura mundial disponibiliza metodologias, técnicas e ferramentas que facilitam o processo de negociação e a tomada de decisão para solucionar os conflitos presentes nestas áreas. O emprego das técnicas e ferramentas, embora mais trabalhoso e exija tempo prolongado se torna mais eficaz. Pois, quando os atores participam ativamente do processo de negociações e encontram as soluções, o comprometimento e a responsabilidade se tornam parte integrante do procedimento de gestão da unidade, e deste desempenho dependem, não somente a sustentabilidade da natureza, mas, a permanência da população na área.

Proposta de trilha interpretativa para a Floresta Estadual Edmundo Navarro de Andrade (FEENA) - Rio Claro

Within the current context of environmental degradation, primarily caused by unsustainable pat terns of production and consumption (AGENDA 21, 1992), the Protected Areas (PAs) are considered internationally as one of the most successful measures for the conservat ion of biodiversity, according to the Union for the Conservation of Nature (IUCN). The city of Rio Claro (Sao Paulo, Brazi l ) has a significant conservation area in both environmental aspects as historical and cultural, the State Forest 'Edmundo Navarro de Andrade' (FEENA). Beyond the conservation measures, there is a need to develop environmental education that encourages community participation and appreciation in the unit 's maintenance and protection, as well as provide moments of reflection that could conduct perceptual changes, behavioral, attitudinal and evaluative on relations between human beings and their environment . This work brings the proposal to create an interpretive trail in the area of public use of FEENA to contribute to the Unit Management Plan in order to make it an Environmental Education tool. To prepare the planning of the interpretive trail, a deep bibliographic and cartographic review was performed on the subject. It was applied questionnaires in order to know the visitors better and map the features of public visitation, as well as map the visitor preferences about how they would like to receive information on the area and expose field studies in the track site. The trail was traced taking into account the environmental and social aspects, we propose a track suspended above the ground, in order to affect as little as possible and to include the area in the context of PAs people with reduced mobility and visually impaired

Implementação das unidades de conservação do corredor central da Mata Atlântica no estado da Bahia: desafios e limites

No Brasil, as Unidades de Conservação (UCs) são consideradas o pilar central para o desenvolvimento de estratégias nacionais de conservação da biodiversidade. Dentro dessa perspectiva, foram estudadas trinta unidades de conservação pertencentes ao Corredor Central da Mata Atlântica no Estado da Bahia, com o objetivo de identificar e analisar seu atual nível de implementação. Foi utilizada, com as devidas adaptações, a metodologia de Lemos de Sá e Ferreira (2000), a qual consiste na aplicação de uma escala de padrão, onde a variação de análise do nível de implementação obedece a um intervalo entre 0 a 5 pontos. Após obter os dados do nível de implementação foi utilizado o método de agregação de Ward para auxiliar a visualização das unidades de conservação estudadas quanto à dissimilaridade entre elas. Utilizou-se a classificação internacional proposta pela IUCN (International Union for Conservation of Nature) para que as UCs sejam comparáveis com trabalhos realizados em outros países. As UCs avaliadas estão nos grupos Ia, II, V e VI da IUCN. Conforme os resultados, 50% das unidades de conservação analisadas encontram-se razoavelmente implementadas, 40% insuficientemente implementadas, 6,7% apresentam-se como "parques de papel" e apenas 3,3% podem ser classificadas como satisfatoriamente implementadas. Essas áreas enfrentam problemas em sua regularização fundiária; apresentam deficiência em infraestrutura, recursos humanos e financeiros. Diante dos resultados, fica evidente a recorrência do fato de que as unidades de conservação em estudo necessitam ser efetivamente implementadas. Para que isso ocorra, as políticas ambientais devem ser voltadas para ações com objetivos de consolidar essa estratégia de conservação.

Seropositivity and Risk Factors Associated with Toxoplasma gondii Infection in Wild Birds from Spain

Toxoplasma gondii is a zoonotic intracellular protozoan parasite of worldwide distribution that infects many species of warm-blooded animals, including birds. To date, there is scant information about the seropositivity of T. gondii and the risk factors associated with T. gondii infection in wild bird populations. In the present study, T. gondii infection was evaluated on sera obtained from 1079 wild birds belonging to 56 species (including Falconiformes (n = 610), Strigiformes (n = 260), Ciconiiformes (n = 156), Gruiformes (n = 21), and other orders (n = 32), from different areas of Spain. Antibodies to T. gondii (modified agglutination test, MAT titer ≥1:25) were found in 282 (26.1%, IC95%:23.5–28.7) of the 1079 birds. This study constitute the first extensive survey in wild birds species in Spain and reports for the first time T. gondii antibodies in the griffon vulture (Gyps fulvus), short-toed snake-eagle (Circaetus gallicus), Bonelli's eagle (Aquila fasciata), golden eagle (Aquila chrysaetos), bearded vulture (Gypaetus barbatus), osprey (Pandion haliaetus), Montagu's harrier (Circus pygargus), Western marsh-harrier (Circus aeruginosus), peregrine falcon (Falco peregrinus), long-eared owl (Asio otus), common scops owl (Otus scops), Eurasian spoonbill (Platalea leucorodia), white stork (Ciconia ciconia), grey heron (Ardea cinerea), common moorhen (Gallinula chloropus); in the International Union for Conservation of Nature (IUCN) “vulnerable” Spanish imperial eagle (Aquila adalberti), lesser kestrel (Falco naumanni) and great bustard (Otis tarda); and in the IUCN “near threatened” red kite (Milvus milvus). The highest seropositivity by species was observed in the Eurasian eagle owl (Bubo bubo) (68.1%, 98 of 144). The main risk factors associated with T. gondii seropositivity in wild birds were age and diet, with the highest exposure in older animals and in carnivorous wild birds. The results showed that T. gondii infection is widespread and can be at a high level in many wild birds in Spain, most likely related to their feeding behaviour.

Promoting Local Innovations: A tool for adaptation to climate change and sustainable development in Mountains

Throughout their history mountain communities have had to adapt to changing environmental and socio-economic conditions. They have developed strategies and specialized knowledge to sustain their livelihoods in a context of adverse climatic events and constant change. As negotiations and discussions on climate change emphasize the critical need for locally relevant and community owned adaptation strategies, there is a need for new tools to capitalize on this local knowledge and endogenous potential for innovation. The toolkit Promoting Local Innovation (PLI) was designed by the Centre for Development and Environment (CDE) of the University of Bern, Switzerland, to facilitate a participatory social learning process which identifies locally available innovations that can be implemented for community development. It is based on interactive pedagogy and joint learning among different stakeholders in the local context. The tried-and-tested tool was developed in the Andean region in 2004, and then used in International Union for Conservation of Nature (IUCN) climate change adaptation projects in Thailand, Burkina Faso, Senegal, and Chile. These experiences showed that PLI can be used to involve all relevant stakeholders in establishing strategies and actions needed for rural communities to adapt to climate change impacts, while building on local innovation potential and promoting local ownership

Efetividade das áreas protegidas para a conservação da natureza sob a abordagem dos serviços ecossistêmicos na bacia do rio Corumbataí

A sustentabilidade da paisagem trata-se de um tema central no que se refere às questões de conservação e desenvolvimento de paisagens altamente antropizadas. Está embasada nos conceitos tradicionais de desenvolvimento sustentável, que visam balancear o desenvolvimento humano com a proteção ambiental, pautada na equidade intra e extra-geração. Considera, ainda, os conceitos de bem-estar humano nesta esfera. Paralelamente, os conceitos de serviços ecossistêmicos reconhecem a dependência das atividades antrópicas e seu bem-estar à qualidade dos ecossistemas, reacendendo os debates sobre capital natural e desenvolvimento sustentável. Neste contexto, este trabalho aborda a sustentabilidade da paisagem questionando a potencialidade dos remanescentes florestais em fornecer, de maneira equilibrada, diferentes serviços ecossistêmicos na bacia do rio Corumbataí. Para isso, o trabalho foi dividido em duas etapas. A primeira buscou analisar questões de demanda e oferta por múltiplos serviços ecossistêmicos (controle de erosão, regulação hídrica, regulação microclimática, informação estética e qualidade de habitat). Isso baseado em indicadores da paisagem, como a dinâmica do uso do solo e padrões do meio físico e antrópico. A segunda investigou a viabilidade de integrar o sinergismo entre os serviços de controle de erosão e qualidade de habitat às prioridades de conservação e restauração florestal. Isso baseado no cenário atual da paisagem e por meio de diferentes simulações de incremento em 10% da cobertura florestal na paisagem, inserindo florestas nos locais de alta erodibilidade (situação criteriosa) ou de forma randômica. Os resultados demonstraram que, apesar do aumento de 60% na cobertura florestal durante os últimos 30 anos, apenas 37% das florestas possuem alto potencial para ofertar serviços ecossistêmicos e que, quando ponderadas perante as demandas da paisagem, apenas 20% das florestas encontram-se em equilíbrio. Além disso, foi verificado sinergismo entre os serviços de controle de erosão e qualidade de habitat em aproximadamente 80% da cobertura florestal. No entanto, nos cenários de restauração florestal, o sinergismo foi alcançado em todas as situações, sejam elas criteriosas ou randômicas. Deste modo, ficou evidente o limite das florestas e áreas protegidas como potenciais prestadoras de serviços ecossistêmicos na paisagem. Também ficou evidente que, em paisagens com alto grau de fragmentação e baixa proporção florestal, os processos de restauração não necessariamente devem almejar o sinergismo entre serviços ecossistêmicos. Por fim, atribui-se grande importância ao papel das áreas agrícolas e pastagens para compensar demandas, restaurar serviços ecossistêmicos, almejando, portanto, a sustentabilidade da paisagem.
