The Legitimacy of Certification Standards in Climate Change Governance

This article explores the role of two private steering mechanisms, the Forest Stewardship Council (FSC) and the Climate, Community and Biodiversity Alliance (CCBA), in REDD+, the climate change mitigation policy that aims to avoid deforestation and forest degradation in developing countries. It does so by analyzing input and output legitimacy of the two certification standards at the global level, and at national and local levels in Peru. The findings show an increasing interest among REDD+ actors in using these standards, and a relatively large number of Peruvian REDD+ projects that are certified by the FSC or CCBA. The findings also suggest intrinsic linkages between input and output legitimacy of the FSC and CCBA within single governance levels and across different scales. The article also demonstrates the added value of studying the legitimacy of policy instruments, such as the FSC and CCBA, in a specific context such as REDD+.

LONGEVIDADE DE SISTEMAS SÓCIO-NATURAIS: AS ESCALAS TEMPOESPACIAIS, A INOVAÇÃO E AS CIDADES

The discussion about the socio-natural systems’ future sustainability implies the analysis of the impact of human-environment interactions established from various spatial-time scales on the longevity of systems. Indeed, sustainability and sustainable development related research has shown a methodological and conceptual insufficiency in terms of the analysis of extended spatial and temporal scales. Thus, to contribute to the discussion on the topic, it is worth reassessing the prior notions such as 'milieu' and 'cultural environment' have addressed the formation and maintenance of social-natural systems.  A retrospective survey of earlier notions shows that they were based on comprehensive conceptual approaches and suggests relevance of revisiting the role that innovation and urbanisation processes have on the sustainability of socio-natural systems. This paper deals with unexplored analytical, methodological and conceptual issues on the longevity of socio-natural systems.   Key-words: socio-natural systems, spatial-time, scale, innovation, cityA discussão sobre a sustentabilidade futura de sistemas sócio-naturais implica na análise do impacto de interações humana-ambientais estabelecidas a partir de várias escalas tempo-espaciais sobre a longevidade dos sistemas. Efetivamente, a pesquisa relacionada à sustentabilidade e ao desenvolvimento sustentável tem demonstrado uma insuficiência metodológica e conceitual em termos da análise de escalas espaciais e temporais ampliadas. Assim, para contribuir com a discussão do tema, vale reavaliar como noções prévias, tais como ‘milieu’ e ‘meio-ambientes culturais’, trataram a formação e manutenção de sistemas sócio-naturais.  Um levantamento retrospectivo de noções anteriores mostra que elas se baseavam em abordagens conceituais abrangentes e sugere a relevância de revisitar o papel que a inovação e os processos de urbanização têm na sustentabilidade dos sistemas sócio naturais. Este artigo aborda questões analíticas, metodológicas e conceituais ainda pouco exploradas relativas à longevidade de sistemas sócio-naturais.   Palavras-chave: sistemas sócio-naturais, espaço-tempo, escala, inovação, cidade

Future Scenarios as a Tool for Collaboration in Forest Communities

Forest devolution is meant to provide communities with greater decision-making power over the use and future of tropical forests. However, devolution policies have not always had the intended effect; in some cases they have caused or furthered the disenfranchisement of the poor, the creation of open access conditions, resource conflict and forest degradation. These problems are likely to arise when forest communities are at a disadvantage when interacting with other local players and are unprepared for their new opportunities and responsibilities due to their physical remoteness, cultural isolation, low literacy rates or lack of experience in formal planning and negotiation. This paper discusses how a participatory method to facilitate thinking about the future—called future scenarios—can help change the way forest communities and local governments interact. The paper reviews a growing body of literature on future scenarios and shares first-hand experiences with future scenarios in forest communities in the northern Bolivia Amazon and the central provinces of Vietnam. It finds that under the right conditions, the use of future scenarios allows forest communities to collaborate more effectively with local government, better assume responsibilities when given control over forests under devolution schemes and self-organize to benefit from the opportunities that communal control over forests offer. Future scenarios help communities think about dependency, vulnerabilities and ways to prepare for the future; the methods develop organizational capacity and encourage internal democratic processes and planning. Community leaders become more vocal and assertive in meetings with local government, and marginalized groups within communities, such as women or the poorest segments, make their voices heard. However, the methods are less effective when facilitation skills are not available or where government or other interests are threatened by local constituents, Future scenarios are not without their pitfalls and do not work in all situations, but given the appropriate context they can create “break-through moments” that improve collaboration between communities and local officials

Immunostimulatory Effect of Flagellin on MDR-<i>Klebsiella</i>-Infected Human Airway Epithelial Cells

Pneumonia caused by multi-drug-resistant Klebsiella pneumoniae (MDR-Kpneu) poses a major public health threat, especially to immunocompromised or hospitalized patients. This study aimed to determine the immunostimulatory effect of the Toll-like receptor 5 ligand flagellin on primary human lung epithelial cells during infection with MDR-Kpneu. Human bronchial epithelial (HBE) cells, grown on an air–liquid interface, were inoculated with MDR-Kpneu on the apical side and treated during ongoing infection with antibiotics (meropenem) and/or flagellin on the basolateral and apical side, respectively; the antimicrobial and inflammatory effects of flagellin were determined in the presence or absence of meropenem. In the absence of meropenem, flagellin treatment of MDR-Kpneu-infected HBE cells increased the expression of antibacterial defense genes and the secretion of chemokines; moreover, supernatants of flagellin-exposed HBE cells activated blood neutrophils and monocytes. However, in the presence of meropenem, flagellin did not augment these responses compared to meropenem alone. Flagellin did not impact the outgrowth of MDR-Kpneu. Flagellin enhances antimicrobial gene expression and chemokine release by the MDR-Kpneu-infected primary human bronchial epithelium, which is associated with the release of mediators that activate neutrophils and monocytes. Topical flagellin therapy may have potential to boost immune responses in the lung during pneumonia.</p
