Collaborative approaches to local climate change and clean energy initiatives in the USA and England

This paper analyses how 10 localities in the USA and England, recognised as leaders in clean energy and climate action, have used collaborative approaches to develop local climate change plans and energy conservation, efficiency, and renewable energy initiatives. It examines these planning and policy-making processes in the context of Margerum's [2008. A typology of collaboration efforts in environmental management. Environmental Management, 41 (4), 487–500] typology of “action”, “organizational”, and “policy-level” collaborations, as well as Gray's [1989. Collaborating: finding common ground for multiparty problems. San Francisco: Jossey-Bass] classification of collaboration in the “problem-setting”, “direction-setting”, and “implementation” phases. We conducted interviews with local elected officials, municipal staff, energy professionals, and citizen volunteers in each community, supplemented with an analysis of their adopted energy, climate change, and land-use plans. We find that despite the different government structures and political contexts between the two countries, there was a surprising amount of commonality in how the case study localities used collaborative planning to develop local climate plans and clean energy initiatives. These processes were most often initiated by local elected officials and/or high-level staff members, and then carried out in collaboration with local third-sector organisations and other community stakeholders. In the USA, collaboration was strongest at the policy level and in the direction-setting phase, with the distinguishing feature that citizen advisory boards or stakeholder working groups often took a more active role in shaping local plans and policies. The English localities had some of those same types of collaborations, but were more likely to also employ action collaboration, in the implementation phase, in which third-sector organisations coordinated with the locality to directly provide clean energy services.     

Capacity building for food justice in England: the contribution of charity-led community food initiatives

This paper discusses the extent to which charity-led initiatives can contribute to capacity building for food justice in England. The paper draws on evaluations of two projects run by the charity Garden Organic: the Master Gardener Programme, operating a network of volunteers who mentor households, schools and community groups to support local food growing, and the Sowing New Seeds programme, which engages “Seed Stewards” to work with communities to encourage the growing and cooking of “exotic” crops. Based on qualitative data about peoples’ motivations for participation and the benefits that are experienced, we interpret these projects as examples of capacity building for food justice. We suggest that whilst currently depoliticised, the “quiet” process of reskilling and awareness raising that occurs through shared gardening projects could have transformative potential for people’s relationship with food. Finally, we use our findings to raise critical questions and propose future research about food justice concepts and practices.     

Communicating risk for vulnerable groups: a case study of the Mano community’s strategies for collective knowledge to action

This paper discusses the emergent interest in risk communication as a strategy for disaster risk reduction. Communication plays an essential role in understanding risk, but studies suggest that people often do not respond in the way that risk experts anticipate. For risk communication to be effective, vulnerable communities need to understand risk within the local context as well as in terms of sustainability. Risk messages offer communities a way to enhance their collective knowledge of existing vulnerabilities, leading them towards alternative solutions for action. A longitudinal study of the Mano community development approach and its recovery from the 1995 Kobe earthquake illustrates how risk communication dynamics contributed to the community’s sustainable risk reduction. The study concludes that risk communication is a collaborative way for a community to work with risk experts, own their risk information, influence existing policies and practices, develop solutions to reduce vulnerability, and ultimately enhance a community’s capacity for managing future risk.

Enhanced science–stakeholder communication to improve ecosystem model performances for climate change impact assessments

In recent years, climate impact assessments of relevance to the agricultural and forestry sectors have received considerable attention. Current ecosystem models commonly capture the effect of a warmer climate on biomass production, but they rarely sufficiently capture potential losses caused by pests, pathogens and extreme weather events. In addition, alternative management regimes may not be integrated in the models. A way to improve the quality of climate impact assessments is to increase the science–stakeholder collaboration, and in a two-way dialog link empirical experience and impact modelling with policy and strategies for sustainable management. In this paper we give a brief overview of different ecosystem modelling methods, discuss how to include ecological and management aspects, and highlight the importance of science–stakeholder communication. By this, we hope to stimulate a discussion among the science–stakeholder communities on how to quantify the potential for climate change adaptation by improving the realism in the models.     

Striking the balance: Challenges and perspectives for the protected areas network in northeastern European Russia

Increasing anthropogenic pressure on the largest remaining tracts of old-growth boreal forest in Europe necessitates additional conservation of ecosystems and biodiversity in northeastern European Russia. In a regional network comprising 8 % of the Nenets Autonomous District and 13.5 % of the Komi Republic, 248 areas have varying protected statuses as state nature reserves (zapovedniks), national parks, reserves/sanctuaries (zakazniks), or natural monuments. Due to increased natural resource extraction in this relatively pristine area, designation of additional protected areas is critical for the protection of key ecological sites. The history of ecological preservation in these regions is herein described, and recent recommendations for incorporating additional ecologically representative areas into the regional network are presented. If the protected area network can be expanded, the overall environmental stability in these globally significant ecosystems may remain intact, and can help Russia meet the 2020 Aichi conservation targets, as set forth by the Convention of Biological Diversity.     

改性SCAC催化臭氧氧化去除布洛芬效能与反应活性位点研究

采用不同的表面改性方法(去矿化处理、氧化改性、碱改性和还原改性)对污泥基活性炭(SCAC)进行处理,分别获得了表面金属含量低、碱位低、碱性官能团含量高及Lewis碱含量高的4种改性SCAC(SCAC-D、SCAC-S、SCAC-OH和SCAC-N),对比考察了改性前后SCAC催化臭氧氧化去除布洛芬(IBP)的效能,并探讨了SCAC催化臭氧氧化反应的主要活性位点。结果表明,5种SCAC催化活性顺序为:SCAC-N>SCAC-OH>SCAC>SCAC-S>SCAC-D;金属组分减少会直接影响SCAC的催化活性,碱位减少对其催化活性的影响相对较弱,说明SCAC表面较为丰富的金属组分是其催化臭氧氧化反应的主要活性位点;增加SCAC表面碱位(Lewis碱和碱性官能团),减少表面酸性官能团有助于提高其催化活性。

Variations of Bacterial Community Structure in Flooded Paddy Soil Contaminated with Herbicide Quinclorac

The denaturing gradient gel electrophoresis (DGGE) method was applied to determine the relative genetic complexity of microbial communities in flooded paddy soil treated with herbicide quinclorac (3,7-dichloro-8-quinoline-carboylic acid). The results obtained showed a significant effect of quinclorac on the development of bacterial populations in soils contaminated with different concentrations of the herbicide at the early time after application. In general, however, the number of populations of the same soil sample treated with the same concentration of the quinclorac differed obviously with increasing incubation time within the early 8 weeks. The scale of differences in banding patterns-showed that the microbial community structures of the quinclorac-treated and non-quinclorac-treated soils were not significantly different after 21 weeks of incubation. Quantification, as demonstrated in this paper, was studied by establishing dose-response relationships. Significant pattern variations were quantified. Prominent DGGE bands were excised, cloned and sequenced to gain insight into the identities of predominant bacterial populations. The majority of DGGE band sequences were related to bacterial genera Clostridium, Sphingobacterium, Xanthomonas and Rhodococcus.     

Effects of methamidophos on the community structure,antagonism towards Rhizoctonia solani,and phlD diversity of soil Pseudomonas

A microcosm incubation study using an aquic brown soil from northeast China (a Cambisol in the UN Food and Agriculture Organization FAO Soil Taxonomy) was conducted to examine the effects of different concentrations (0, 50, 150, and 250 mg kg^?1) of methamidophos (O,S-dimethyl phosphoramidothioato) on Pseudomonas, one of the most important gram-negative bacteria in soil. Amplified ribosomal DNA restriction analysis (ARDRA) was performed to study the Pseudomonas community structure, an in vitro assay was made to test the antagonistic activity of isolated Pseudomonas strains against soil-borne Rhizoctonia solani, a major member of the pathogens highly related to soil-borne plant diseases, and special primer amplification and sequencing were performed to investigate the diversity of phlD, an essential gene in the biosynthesis of 2, 4-diacetylphloroglucinol (2, 4-DAPG), which has biocontrol activity in phlD ⁺isolates. With exposure to increasing methamidophos concentrations, the total number of soil Pseudomonas ARDRA patterns decreased significantly, but with less change in the same treatments over 1, 3, and 5 weeks of incubation. The number of isolated Pseudomonas strains with antagonistic activity against R. solani as well as the diversity and appearance frequency of the strains' phlD gene also decreased with increasing concentrations of methamidophos, especially at high methamidophos concentrations. Applying methamidophos could increase the risk of soil-borne plant diseases by decreasing the diversity of the soil Pseudomonas community and the amount of R. solani antagonists, particularly those with the phlD gene.
