The European Marine Strategy: Contribution and challenges from a Portuguese perspective

The EU Marine Strategy Framework Directive (MSFD) is considered to be the environmental pillar of the EU Integrated Maritime Policy, establishing a framework within which member states must take the necessary measures to achieve, or maintain, good environmental status in their marine waters. This study presents Portugal's contributions to the Directive development, describes the Portuguese institutional framework within the MSFD and, finally, highlights the opportunities and threats to the success of the MSFD implementation in Portugal. The latter entails an analysis of the Directive's long term adequacy in its link to (1) marine spatial planning, (2) climate change and (3) the economic/financial crisis. With one of Europe's largest exclusive economic zones. Portugal's interest in the MSFD is paramount. Efforts towards the approval of the final document were assured during the Portuguese presidency of the European Council of Ministers, in 2007, while chairing a thorough discussion between the Council and the European Parliament. In the Portuguese context, the Directive implementation will rely on the Water Institute as the authoritative entity, which will be responsible for coordinating all necessary efforts at the national level. The success of such process depends on a close cooperation among the institutions involved as well as on how approved measures account for long term issues. In addition, the MSFD implementation must be built on lessons learned within the Water Framework Directive, in order to be successful. Although it poses a methodological challenge to Portugal, the MSFD implementation is expected to contribute significantly to the improvement of coastal/marine conservation and management at the national level.

近40a来基于树轮年代学的梅里雪山明永冰川变化研究

由于冰川观测资料在时空分布上的匮乏,关于梅里雪山地区冰川进退的研究很少,限制了对本区冰川进退的时间和规模及其与气候间相关性的等方面的认知. 树轮年代学方法作为冰川进退历史定年的有效手段,在世界上已经被广泛采用. 通过对采自冰川末端冰碛上的树轮样本进行分析,利用GIS结合地形图与野外GPS点冰川边界确定,研究和分析了明永冰川年近40a来的冰川进退变化. 为进一步的树轮冰川学研究提供支持,也为预估未来变化趋势提供重要的科学基本数据.

Biocrust landscape-scale spatial distribution is strongly controlled by terrain attributes: Topographic thresholds for colonization in a semiarid badland system

Biological soil crust, or biocrust communities, are the dominating life form in many extreme habitats, such as arid and semiarid badlands, where water scarcity and highly erodible substrates limit vegetation cover. While climate, soil and biotic factors have been described as environmental filters influencing biocrust distribution in such biomes, little is known about the effect of terrain attributes on creating specific microhabitats that promote or restrict biocrust colonization. This study aimed to identify the main terrain attributes controlling biocrust distribution in the driest badland system in Europe, the Tabernas Badlands (SE Spain). To do this, we analysed the influence of different terrain attributes related to landscape stability and microclimate formation on the spatial distribution of lichen and cyanobacteria, using field measurements and topographical information from a LiDAR survey. Our results showed that the spatial distribution of cyanobacteria-dominated biocrusts, which are physiologically and morphologically adapted to extreme drought and high UVA radiation, was mostly associated with areas of high potential incoming solar radiation. The exception was bare south-aspect hillslopes with very high sediment transport potential, where bare physically crusted soils were the dominant ground cover. Lichen-dominated biocrusts, in contrast, colonized near the top of north-aspect hillslopes, characterized by low potential incoming solar radiation and potential evapotranspiration, and their cover decreased downstream, as conditions became good enough for vascular plants. © 2019 John Wiley & Sons, Ltd. © 2019 John Wiley & Sons, Ltd.     

建设海洋强国的政治学解释——基于注意力配置的分析

基于注意力政治学的领导人注意力分析框架,对自2012年以来建设海洋强国这一国家级海洋战略的启动和实施进行分析,探讨建设海洋强国的作用机制。文章提出：1）领导人与政府有限的注意力是国际体系结构变化与国家行为产生之间的中介变量。2）国际局势变化、地方政府竞争、突发事件刺激和以往的从政经历是建设海洋强国的触发因素,驱使领导人和政府的注意力发生转移。3）领导人通过讲话、批示、视察等活动推动政策实施,这是测量领导人及政府对于建设海洋强国的注意力依据。注意力对建设海洋强国的作用机制体现在：1）国家海洋战略重置后,领导人与政府的注意力继续作用于新海洋战略的实施过程;2）领导人通过自身一系列的活动,如视察、批示,加快海洋战略的运行;3）通过设立高级别机构,高位推动建设海洋强国;4）通过国家媒体对海洋事务的持续议程设置,固定公众和社会注意力。上述作用机制有效地引导并锁定了中国对海洋事务的关注方向与重点,改变了传统中国“重陆轻海”的战略文化与社会认知。
