“Love for sale”: Biodiversity banking and the struggle to commodify nature in Sabah,Malaysia     

《Geoforum》2015

In Malaysia, second largest palm oil producer worldwide, logging companies, palm oil corporations, and even responsible citizens can now compensate their biodiversity impacts by purchasing Biodiversity Conservation Certificates in an emerging new biodiversity market: the Malua BioBank. Biodiversity markets are part of a wider trend of marketisation and neoliberalisation of biodiversity governance; introduced and promoted as (technical) win–win solutions to counter biodiversity loss and enable sustainable development. The existing neoliberalisation and nature literature has tended to analyse these processes as consequences of an inherent drive of capital to expand accumulation and submit ever more areas of nature to the neoliberal market logic.In contrast, I aim (a) to problematise the agency and the “work” behind marketisation of biodiversity, challenging the story of (corporate-driven) neoliberalisation as the realisation of an inherent market-logic (based on the a false conceptual state–market divide, often prevalent even in activist academic circles working on neoliberalisation of nature) and to see the state not only as regulator, but driving force behind, and part of “the market”; (b) to question the myth of neoliberalisation as state losing control to the market and to show how the state is using the biodiversity market as mode of governing; re-gaining control over its forests and its conservation policy; and (c) to demonstrate empirically the distinction between neoliberal ideology and practice, and to show that marketisation was based on pragmatic decisions, not ideology-driven political action. My analysis is based on 35 qualitative interviews with actors involved in the BioBank.  相似文献   

“Yes to Peace”? Environmental peacemaking and transboundary conservation in Central America     

《Geoforum》2015

The use of transboundary conservation as tools for improving interstate relations has become a widely supported initiative in nature conservation. The rationale follows the environmental peacemaking hypothesis, which argues that seemingly neutral environmental issues can provide a sound basis for cooperation between states. The paper investigates the hypothesis’ premise through the case of International System of Protected Areas for Peace (Si-A-Paz), a transboundary protected area shared by Costa Rica and Nicaragua. In recent years, both countries have been involved in a number of border conflicts within Si-A-Paz and linked to the use of the San Juan River, contested land areas, and oil resources. The case of Si-A-Paz shows that transboundary environmental issues can provide arguments for maintaining or even strengthening conflicts rather than fostering peace between states. The case also shows the emergence of environmental issues as a new arena for geopolitical play, where actors not only justify their actions through an environmental discourse but also, the environmental discourse is stretched to include a variety of issues through which actors can obtain international support. The events in Nicaragua and Costa Rica raise questions about the role of transboundary conservation as a peacebuilding tool.  相似文献   

DISCREPANCY OF THE GLOBAL AIR MASS AND WATER BUDGETS AMONG 20 CMIP5 CLIMATE MODELS     

秦育婧  卢楚翰  管兆勇  智海 《热带气象学报(英文版)》2015,21(3):265-275

The consistency of global atmospheric mass and water budget performance in 20 state-of-the-art ocean–atmosphere Coupled Model Intercomparison Project Phase 5 (CMIP5) coupled models has been assessed in a historical experiment. All the models realistically reproduce a climatological annual mean of global air mass (AM) close to the ERA-Interim AM during 1989–2005. Surprisingly, the global AM in half of the models shows nearly no seasonal variation, which does not agree with the seasonal processes of global precipitable water or water vapor, given the mass conservation constraint. To better understand the inconsistencies, we evaluated the seasonal cycles of global AM tendency and water vapor source (evaporation minus precipitation). The results suggest that the inconsistencies result from the poor balance between global AM tendency and water vapor source based on the global AM budget equation. Moreover, the cross-equatorial dry air mass ?ux, or hemispheric dry mass divergence, is not well represented in any of the 20 CMIP5 models, which show a poorly matched seasonal cycle and notably larger amplitude, compared with the hemispheric tendencies of dry AM in both the Northern Hemisphere and Southern Hemisphere. Pronounced erroneous estimations of tropical precipitation also occur in these models. We speculate that the large inaccuracy of precipitation and possibly evaporation in the tropics is one of the key factors for the inconsistent cross-equatorial mass ?ux. A reasonable cross-equatorial mass ?ux in well-balanced hemispheric air mass and moisture budgets remains a challenge for both reanalysis assimilation systems and climate modeling.  相似文献   

Co-productive governance: A relational framework for adaptive governance     

《Global Environmental Change》2015

Adaptive governance focuses our attention on the relationships between science and management, whereby the so-called ‘gaps’ between these groups are seen to hinder effective adaptive responses to biophysical change. Yet the relationships between science and governance, knowledge and action, remain under theorized in discussions of adaptive governance, which largely focuses on abstract design principles or preferred institutional arrangements. In contrast, the metaphor of co-production highlights the social and political processes through which science, policy, and practice co-evolve. Co-production is invoked as a normative goal (Mitchell et al., 2004) and analytical lens (Jasanoff, 2004a, Jasanoff, 2004b), both of which provide useful insight into the processes underpinning adaptive governance. This paper builds on and integrates these disparate views to reconceptualize adaptive governance as a process of co-production. I outline an alternative conceptual framing, ‘co-productive governance’, that articulates the context, knowledge, process, and vision of governance. I explore these ideas through two cases of connectivity conservation, which draws on conservation science to promote collaborative cross-scale governance. This analysis highlights the ways in which the different contexts of these cases produced very different framings and responses to the same propositions of science and governance. Drawing on theoretical and empirical material, co-productive governance moves beyond long standing debates that institutions can be rationally crafted or must emerge from context resituate adaptive governance in a more critical and contextualized space. This reframing focuses on the process of governance through an explicit consideration of how normative considerations shape the interactions between knowledge and power, science and governance.  相似文献   

Marine management for human development: A review of two decades of scholarly evidence     

Gonçalo Carneiro 《Marine Policy》2011

This paper reviews the evidence of the impacts of marine management interventions on human development and well-being reported in marine management literature in the past two decades. Documents dealing with fisheries, aquaculture, marine conservation and coastal zone management are assessed in terms of the methodologies used, the human development dimensions considered, and the results reported. The choice of dimensions for defining human development in this literature is contrasted with proposals from the literature on the capability and human development approaches. Possible areas for future research are discussed.  相似文献

Effects of sand grain size and morphological traits on running speed of toad-headed lizard Phrynocephalus frontalis     

C. LiX. Lian  J. BiH. Fang  T.L. MaulZ. Jiang 《Journal of Arid Environments》2011,75(11):1038-1042

We conducted a manipulative experiment to investigate the influential factors of locomotor ability in steppe toad-headed lizards. By using a video-base method, we measured running speed of the lizards when they run on sands of different grain sizes. We also considered body condition, tail length and sex as fixed factors to analyze their effects on running speed of the lizard. Results showed that running speed of the lizard significantly differed among different trials of sand grain size. Specifically, the peak and the nadir values of the running speed were found on sands of 0.5-1 mm and 0.075-0.25 mm grains, respectively. When lizards ran on sands of different grain size their running speed changed significantly. Body condition and tail length also had significant effects on running speed. The findings indicated that locomotor ability of lizards depended on both body condition and the external environment. We hypothesized that sand grain size is one of the factors that influence the habitat selection in steppe toad-headed lizards. Moreover, this lizard may be used as an indicator of the development of sand dunes.  相似文献   

Discussion on the relationship between longitudinal cracks and alignment of subgrade in permafrost regions     

AnHua Xu 《寒旱区科学》2011,3(2):0132-0136

At present, embankment longitudinal cracks are a major problem in highways through permafrost regions, and seriously affect traffic safety and the normal operations of the highway. In the past, roadbed height in permafrost regions was relatively low, and embankment cracks were rare and did not affect traffic safety. Thus, highway designers and researchers paid little attention to this problem, and they knew very little about distribution laws and mechanism of embankment longitudinal cracks. Due to this lack of knowledge, there is no uniform opinion on this problem, making it difficult to find measures that will mediate the impact of longitudinal cracks. Temperature is a major factor that affects and controls embankment stability in permafrost regions, especially in ice-rich and high-temperature regions, and solar radiation is the principal factor that determines surface temperatures. Under higher embankment, the difference of temperature will be larger between a sunny slope and a shady slope. Hence, the probability for longitudinal cracks generation is higher. In this paper, a survey and analysis of longitudinal cracks along the Qinghai-Tibet Highway were carried out. The longitudinal cracks are found to be related to the road strikes. Solar radiation is considered to play an important role in the generation of longitudinal cracks.  相似文献
