针对气候变暖采取稳健的适应措施已成为国际社会共识。该文综合了当前适应气候变化的国际谈判进展及已有的农业适应气候变化措施,指出适应资金严重不足,技术研发、应用与转让难以实施,以及适应气候变化行动实施能力的不足严重制约着适应气候变化行动的有效实施;关于农业适应气候变化的技术措施仍缺乏系统的理论研究与应用示范。在此基础上,提出了未来中国农业适应气候变化需要重点开展的研究任务,即农业气象灾变过程的新特点及其风险管理, 农业适应气候变化的大数据决策管理系统研发及适应气候变化的农业气候区划与减灾保产技术研究,以切实推进农业适应气候变化,为确保国家粮食安全与农业可持续发展提供支撑。 相似文献

This article provides a historical account of Chinese public policy on fisheries subsidies, and a discussion of problems and limitations resulting from the World Trade Organization (WTO) Doha Round fisheries subsidies negotiation. By analyzing subsidization trends and applying a proportional assessment of subsidized areas, the article tracks the evolvement of Chinese fishery policy objective and priorities. Chinese fishery is not historically significantly subsidized in light of its relatively market-oriented structure and a sustained momentum in reducing marine capture capacity. However, due to the commitment to encouraging qualitative growth and to satisfying a rising domestic demand for fish, the government seeks for adequate policy space to employ fuel, distant water fisheries, infrastructure and various ‘green light’ subsidies. Whether or not such a claim can be accepted as a developmental right not an exception remains to be answered by the revision of current negotiation draft. 相似文献

以广州石屋新村为案例地,通过深入访谈、参与式观察以及收集文本材料等方式获取素材,运用扎根理论进行编码分析,探讨旅游发展背景下乡村空间正义主体博弈与协商的维度与过程。研究发现：① 乡村空间正义主体博弈与协商的内容主要包括分配正义、居住正义、边界正义和信仰正义4个维度,贯穿4个维度的核心和焦点是权力正义。② 4个维度彼此交织,相互影响,前2个维度呼应了马克思空间正义思想的部分观点,后2个维度是中国语境下的理论创新。③ 乡村转型发展过程中杂糅了政府、企业、村民各自的诉求,导致不同主体展演了多元复杂动态的空间正义博弈与协商过程。 相似文献

利马气候大会达成的《利马气候行动号令》明确了《联合国气候变化框架公约》所有原则,尤其是共同但有区别的责任原则适用于拟于2015年巴黎会议达成的新协议。会议还就“国家自主决定的贡献”等做出了决定。利马大会成果对2015年巴黎气候大会达成气候变化新协议具有重要推动作用。面对2020年后的新挑战,中国需尽快制定应对气候变化法,建立碳排放交易机制,促进对应对气候变化先进技术投资,以及加大参与治理国际气候变化事务力度。 相似文献

While the concept of urban agriculture investigates the way in which disused land within the consolidated city is returned to its citizens through a variety of farming practices, many pockets of rural land in peri-urban areas continue to be contested by institutions and communities – including informal farmers, formal farmers, municipal planners, metropolitan agencies, and investors – with contrasting interests. To date however, little scholarly attention has been paid to informal practices within the degraded areas of urban fringes and, more specifically, to the link between the expansion of peri-urban agriculture and the civic appropriation and negotiation of space in neglected peripheral areas. In this paper, we ask how a metropolitan sustainability fix is produced and contested both materially and discursively. We also explore how local residents involved in peri-urban agriculture claim the use of land for agricultural practices and in turn attempt to influence the urban agenda of the neoliberal city. Inquiring how competing visions of nature act as obstacles in this negotiation process, our analysis of the peri-urban Baix Llobregat Agricultural Park in Barcelona reveals that the imposition of official visions about how needs for food and agriculture should be fulfilled, which landscapes are esthetically acceptable, what nature is, and how land should be controlled and developed indicate why apparently “marginal” and informal urban agriculture in the periphery has come to be subordinated to the planning of the neoliberal city and of a metropolitan sustainability fix – a partial sustainability fix that is however progressively being questioned and renegotiated. 相似文献

Despite refinement in scientific methods of setting total allowable catches (TACs), the choice of values is affected by uncertainty that arises as a result of incomplete information and the behavioural intentions of resource users, among others. In this context, this paper promotes ‘anchoring’ – which is a subject of behavioural economics and is generally practised in decision-making when faced with uncertainty – as an approach to TAC setting. We estimate a set of anchor points for nine demersal species by employing two modelling scenarios, the first using catch-and-effort data and the second only catch data collected from the demersal trawl fishery. A non-parametric test yielded no significant difference between the sets of anchor points generated from the two models. It is hoped that the use of anchoring would constitute a proactive management approach that could serve as a mechanism of promoting knowledge integration and effective communication, developing mutual trust, and improving management outcomes in the future. 相似文献

This paper argues that in generating perceptual meanings of social actors as data, researchers need to deal with multiple representations, identities and categorisations of their own and those of their informants. The need to also consider power dynamics that develop in the communication process between the “researcher” and the "researched" in the process of generating data is also emphasised. The paper suggests that an analysis of image‐conflicts can be used to reveal the “hidden meanings” during these research encounters and improve the quality of research findings. 相似文献

国际气候制度的谈判错综复杂。然而,2012年以后国际气候承诺的基础,仍将取决于各国的政治意愿、经济利益和科学认知。谈判的平台不仅限于缔约方会议,也可能是缔约方会议体制外的双边、多边乃至单边形式,而且,协议内容将涉及减排、适应、技术、低碳发展等,最终将可能形成在可持续发展框架下适应与减缓气候变化的综合性一揽子协议。中国在未来20 a或更长时间仍将处于快速工业化和城市化的进程,对协议内容的选择只能是弱化各种风险,规避刚性约束,需要积极参与国际规制的制定,保障并强化中国的可持续发展。 相似文献

中国过渡区域经济运行协调和发展机制分析 总被引：5，自引：1，他引：4
过渡区域由于其共同利益的非均衡性而使协调机制本身存在较大缺陷,因此,在调整过渡区域经济协调方式时必须在遵循发展、互利和协商、逢主和平行的原则基础上作好以下几方面的制度安排：（１）以市场为基础经济协作区;（２）充分发挥过渡区域优势,建立和完善发展极,形成纵横交错的产业带网络;（３）建立和完善过渡区域市场,推动过渡区域经济的发展;（４）建立新型的区际利益协调机制,充分发挥过渡区域经济运行协调机制的作用 相似文献
