三峡库区生态安全问题与对策

具体分析了三峡库区自然、社会和经济三方面的生态安全问题。采用相对资源承载力的研究思路与计算方法，得出该地区超载人口占该地区总人口的比例达37．4％，人地矛盾日益突出的结论。针对三峡库区的生态安全问题，提出了如下的对策：建立科学合理的生态补偿机制和库区立体管理模式；建立库区生态安全预警系统和绿色GDP核算体系；倡导各产业在生态安全下的生产经营运行模式；建立库区县市级管理责任定位体制，明确不同部门、地区所对应的库区生态流域单元的管理权限和责任：积极引导公众进行安全生产和科技减灾。     

大丰市滩涂生态系统服务价值评估

利用遥感技术,通过对TM影像的解译,分析了江苏省大丰市不同历史阶段滩涂开发状况。运用Costanza方法计算了滩涂生态系统的服务价值。研究结果表明,在1984年至2002年18a间,由于缺乏科学规划,滩涂开发对大丰市滩涂生态系统服务功能造成损害;与1997年相比,2002年大丰市滩涂生态系统服务价值损失达88.38万美元,减少33.46%。     

土壤学与广东持续农业的发展

持续农业是关于建立资源、生态、地力、经济效益等各个方面均可持续发展的农业制度的一种思想．水土流失、土地退化、耕地锐减、环境污染，制约着广东农业的持续发展．土壤学应围绕持续农业开展研究工作．目前应加强土壤生态环境的保护，防治土地退化，提高土壤肥力，保证耕地生产力的持续发展．应开展土壤资源的动态变化研究，为合理开发和利用土壤资源提供科学依据．

Integrated shoreline management and tourism development on the cross-border World Heritage Site: A case study from the Curonian spit (Lithuania/Russia)

The varied and very dynamic landscape with a high biological diversity is a distinctive feature of the Curonian spit at the regional scale. Throughout the 20th century the main morphodynamic trend in the littoral of the Curonian spit was shoreline grading on the lagoon side, whereas on the marine side the increasing erosion at the foot of the spit, and increasing accretion at the head of the spit prevailed. The results of a discriminant analysis (Wilkes’ λ = 0.001626 and F = 29.267 when p < 0.001) show that sites with prevailing erosion, accretion and sediment input from the drifting dunes form regular inter-related spatial structures in the littoral with distinctive resulting discontinuities of the sediment drift along the lagoon coast. Dune littoral cells are characterized by Aeolian sediment input and distribution ‘down-drift’, (usually northwards) from the source. The most likely changes in the current development trends of the lagoon shore zone of the Curonian spit are related to expected climate changes and further slowing down of the dune drift. The probability of storms and ice-drift events, and their impact on coasts is expected to increase as a result of climate change. The dune advance will gradually slow down, and with it, the sand input to the coastal zone will decline. In this paper, we define integrated shoreline management as a system of long-term shoreline management measures, which is based on a littoral cell approach and aimed at harmonizing human activity in the coastal zone with the natural development of the shoreline. We propose an integrated management program for the lagoon shoreline of the Curonian spit, which is site-specific for each littoral cell as a coastal management unit. Drifting dunes and seaside beaches are the natural amenities, which are best known and best appreciated on the Curonian spit by 49% of the respondents representing the total Lithuanian population. A responsible tourism development should be considered as the key means for proper appreciation of the drifting dunes and natural coasts by society, which means to acknowledge and cherish the aesthetic and conservation values of dune and coastal landscapes of the Curonian spit as a World Heritage Site. There are at least two pre-conditions for this: (1) to provide visitors with sufficient information about diverse values and functions of the Curonian dunes and coasts within a broader regional and global heritage conservation context; (2) to enable tourists to enjoy the most impressive dune and coastal landscapes at close range. In this paper we propose to encourage active dune tourism, to reintroduce grazing into the Curonian dune areas, to restore and to preserve the most impressive landscapes of the highest white drifting dunes by bringing the blown out sand from the leeward foot of the dunes back to the crest artificially.

The importance of compatible beliefs for effective climate policy integration

ABSTRACT

European climate policy faced increasing constraints during the economic and Eurozone crises (2008–2014). The European Commission subsequently refocused policymaking toward integrating climate objectives into other policy areas such as energy and the 2014–2020 European Union (EU) budget. The conditions for successful climate policy integration (CPI) are analyzed, focusing on the compatibility of key actors’ beliefs. In renewable energy policy, CPI was successful as long as the co-benefits and related policy-core beliefs of energy security, rural economic development and climate action coexisted harmoniously. Once conflict among these policy-core beliefs emerged during the biofuels controversy, CPI was weakened as actors with competing economy-focused beliefs controlled the decision-making process. The case of EU budget climate mainstreaming illustrates how actors can add climate objectives into legislation despite meaningful discussion being ‘crowded out’ by other priorities. The findings highlight the importance of low conflict between departments, compatible beliefs and policy priorities for successful CPI.
