通过可持续认证推动农林牧渔领域自然资源保护

1992年里约环境发展大会后可持续发展成为各国和各界的共识,但经历了二十年的发展,自然资源保护与可持续发展之间的矛盾仍然存在,特别是农林牧渔等领域自然资源的合理开发利用仍待进一步发展。我国作为国际农林牧渔产品的重要消费国和贸易国,在积极推动国内资源的可持续利用同时,也可以通过国际贸易在全球自然资源可持续利用中发挥积极作用。可持续认证作为应对资源保护与经济发展这一矛盾的较为有效的市场手段,经过近二十年的发展已经涵盖了农林牧渔领域的多个产品,在国际上的发展势头强劲,对于自然资源的保护和可持续利用发挥了对政府政策的补充作用。但可持续性认证在我国国内的企业和消费者中还没有得到广泛认识,其通过市场机制引导企业实践可持续经营、落实企业社会责任的作用在国内还没有得到有效的发挥。因此,本研究的目的是通过对可持续认证的分析,为在我国农林牧渔领域更好地发挥其市场推动力提出政策建议。本研究首先综述了可持续认证在国际上的发展历程、产生的影响,详细论述了森林、棕榈油、野生海产品等可持续认证已经在全球贸易中占有一席之地,并在欧美等较发达国家和地区获得了消费者的支持;其次,本研究对可持续认证在农林牧渔领域的进一步发展所面临的挑战进行了剖析,肯定了可持续认证在调动企业和消费者的积极性、推动农林牧渔领域资源保护方面的正面作用,也指出认证对资源保护的预期效果没有完全达到、同一产业内认证体系可靠性参差不齐,着重强调了可持续认证在发展中国家的发展面临的困难,使其对自然资源保护的应有效果受到影响。在此基础上,本研究分析了我国农林牧渔领域在资源利用方面面临的国际和国内压力,尤其是我国在国际贸易中举足轻重的地位和进口大宗产品产地的生态脆弱性使中国在全球资源的可持续利用和保护中可以发挥重要作用,论证了可持续认证在我国的推广有利于提升中国企业的国际形象、促进贸易杠杆发挥资源保护的撬动作用、保障企业在海外开发中的长期效益,同时也有利于我国国内自然资源的可持续利用,明确得出在我国农林牧渔领域推动可持续认证的必要性。本研究建议我国政府部门应关注农林牧渔领域可持续认证在国际和国内的发展,收集相关的信息和案例可用于相关的国际谈判和对企业的指导。同时政府应鼓励国内外认证体系在中国开展认证工作,并为同一产业中的不同体系创造公平的竞争环境。另外,政府应积极支持国内农林牧渔产业的企业、专家、协会等参与到国际认证体系的建立过程中,将中国可持续发展的良好操作范例或规范国际化。政府自身的消费行为对全社会有明确的引导作用,所以在政府采购中应优选可持续认证产品,引导企业加入可持续经营的实践。     

INTERNATIONAL TRADE,ECO-LABELLING,AND SUSTAINABLE FISHERIES – RECENT ISSUES,CONCEPTS AND PRACTICES

Certification of where, when and how fish are caught is emerging as an important fisheries management tool. The history of eco-labelling in the fisheries sector is relatively short and actual experiences of eco-labelling are limited, although an emerging trend is shaping in European and US markets. Eco-labelling in fisheries gained increased impetus with the development of the non-government Marine Stewardship Council (MSC) in 1996. This paper reviews the emerging importance of certification and eco-labelling in the fisheries sector, the development and operation of the MSC, identifying particularly the role of ‘third party certification’ as promoted by the MSC, and notes the opportunities and challenges for the MSC and eco-labelling in general.     

Public–Private Governance Patterns and Environmental Sustainability

This paper discusses public–private governance patterns which have emerged in global environmental management. These patterns originate from a spontaneous non-governmental basis or have intentionally been created and constructed by international organisations or states. The paper identifies four patterns of environmental governance between international organisations, governments and private actors. Theoretically governance patterns in which private actors play a prominent role, pose a challenge to state sovereignty and remould the traditional state centric pattern of environmental management. However, the article emphasises the fact that these patterns remain no more than constructs of international organisations, non-governmental organisations and governments, whose first priorities are not always environmental conservation. The paper suggests that the oldest public–private type of environmental governance, in which the environmental organisations are in advocacy roles, reform environmental management in a more concrete and sustainable way than the more recently emerging patterns.     

A new shock tube configuration for studying dust-lifting during the initiation of a coal dust explosion

The traditional defence against propagating coal dust explosions is the application of dry stone dust. This proven and effective safety measure is strictly regulated based on extensive international experience. While new products, such as foamed stone dust, offer significant practical benefits, no benchmark tests currently exist to certify their dust lifting performance in comparison to dry stone dust. This paper reviews the coal dust explosion mechanism, and argues that benchmark testing should focus on dust lifting during the initial development of the explosion, prior to arrival of the flame. In a practical context, this requires the generation of shock waves with Mach numbers ranging from 1.05 to 1.4, and test times of the order of 10's to 100's of milliseconds. These proposed test times are significantly longer than previous laboratory studies, however, for certification purposes, it is argued that the dust lifting behaviour should be examined over the full timescales of an actual explosion scenario. These conditions can be accurately targeted using a shock tube at length scales of approximately 50 m. It is further proposed that useful test time can be maximised if an appropriately sized orifice plate is fitted to the tube exit, an arrangement which also offers practical advantages for testing. The paper demonstrates this operating capability with proof-of-concept experiments using The University of Queensland's X3 impulse facility.

Application of Fair Trade certification for wild plants: lessons from a FairWild project in India

Based on a study of an experimental wild plant certification project implemented within a tribal community in India, this paper explores how wild plant collectors respond to two contradictory objectives of certification, namely, conserving a targeted plant species while promoting its sale. By providing economic incentives through certification, the project aimed to induce a shift from the collection of immature berries to mature berries from a targeted tree species. However, the majority of the collectors increased their harvests of mature berries while continuing to collect the same quantities of immature berries. This unanticipated project outcome can be attributed to the unique nature of wild plants as an uncertain income source that requires no investment. Evidently, collectors have developed their own concepts of ecological and economic sustainability derived from this unique income source endowed by nature, and have incorporated the new economic opportunity into their own natural resource management strategies.
