1936～1937年河南旱灾述评

发生在1936～1937年间的大旱灾给河南农业生产造成了巨大损失,由此酿成的大饥荒导致食品奇缺、灾民遍地并大批饿死逃亡、伦理道德丧失.究其原因,除自然界气候变异的客观因素外,社会原因是主要的:农业生产力水平低下和统治者、侵略者的压榨与掠夺,致使国困民穷,无力抗灾;政府的防灾无能、救灾无力使灾情不断加重;水利长期失修、植被遭严重破坏使灾害难以抗御、亦加剧了旱灾.     

生计多样性对农户参与农田生态补偿政策响应状态的影响——以上海闵行区、苏州张家港市发达地区为例

农田生态补偿政策是采用经济手段激励农户对农田生态系统服务功能进行保育和维护,解决因市场失灵造成生态效益外溢的一种有效方式,对于改善农田生态环境、提升农地开敞空间、增加农户收益具有积极作用。论文从发达地区农户生计多样性角度入手,利用结构方程模型分析农户生计多样性对农户参与补偿政策的支持意愿、政策实施效果响应的影响。结果表明:①农户基本特征、家庭特征、生计多样性特征、村庄发展特征在5%的水平下对农户在农田生态补偿政策上的支持意愿具有正向影响;②农户基本特征、家庭特征、生计多样性特征在5%的水平下对农户在补偿政策实施效果上的响应具有正向影响,农户村庄发展特征在5%的水平下对其具有负向影响;③农户生计多样性特征是影响农户补偿政策支持意愿最主要的因素,是影响补偿政策实施效果响应的次要因素。这表明补偿政策实施后,农户生计多样性特征对于提高农户对补偿政策支持意愿与政策实施效果响应方面具有积极的作用。把握三者之间的关系有利于政府制定和完善现有农田生态补偿政策,为引导农户生计多样性发展提供参考。     

旅游发展背景下乡村适应性演化理论框架与实证

乡村转型及适应演化路径是乡村可持续发展领域重要研究内容,对实施乡村振兴战略及其多元目标的实现具有重要理论和现实意义。通过国家制度(战略)变迁关键时间节点,梳理典型案例乡村发展阶段,明确案例乡村转型适应的体制演化特征。在乡村适应性演化理论分析框架构建基础上,以体制转换明显的乡村为实证案例,结合农户调查与深度访谈数据,评估乡村适应演化下系统适应能力(结果)及农户生计响应效果,并基于归纳法和灰色关联分析,揭示乡村体制转换与微观农户生计关联的适应演化路径及机制。研究结果表明:(1)传统农业体制乡村向旅游体制转换后出现乡村经济发展和环境破坏、社会矛盾风险并存局面,农户生计适应选择对乡村转型响应呈现多样化。(2)不同适应路径农户生计恢复力存在显著差异,升级型、扩张型生计恢复力相对较高,维持型和更替型较低。(3)乡村体制转换(R₁到R_n)与农户生计适应(P₁到P₅)呈现协同且分化的演化路径,基础设施、政策扶持以及生态环境因子是乡村转型与农户生计关联适应演化的关键影响变量。     

A Framework of Lessons Learned from Community-Based Marine Reserves and Its Effectiveness in Guiding a New Coastal Management Initiative in the Philippines

Community-based coastal resource management has been widely applied within the Philippines. However, small-scale community-based reserves are often inefficient owing to management inadequacies arising because of a lack of local support or enforcement or poor design. Because there are many potential pitfalls during the establishment of even small community-based reserves, it is important for coastal managers, communities, and facilitating institutions to have access to a summary of the key factors for success. Reviewing relevant literature, we present a framework of lessons learned during the establishment of protected areas, mainly in the Philippines. The framework contains summary guidance on the importance of (1) an island location, (2) small community population size, (3) minimal effect of land-based development, (4) application of a bottom-up approach, (5) an external facilitating institution, (6) acquisition of title, (7) use of a scientific information database, (8) stakeholder involvement, (9) the establishment of legislation, (10) community empowerment, (11) alternative livelihood schemes, (12) surveillance, (13) tangible management results, (14) continued involvement of external groups after reserve establishment, and (15) small-scale project expansion.These framework components guided the establishment of a community-based protected area at Danjugan Island, Negros Occidental, Philippines. This case study showed that the framework was a useful guide that led to establishing and implementing a community-based marine reserve. Evaluation of the reserve using standard criteria developed for the Philippines shows that the Danjugan Island protected area can be considered successful and sustainable. At Danjugan Island, all of the lessons synthesized in the framework were important and should be considered elsewhere, even for relatively small projects. As shown in previous projects in the Philippines, local involvement and stewardship of the protected area appeared particularly important for its successful implementation. The involvement of external organizations also seemed to have a key role in the success of the Danjugan Island project by guiding local decision-makers in the sociobiological principles of establishing protected areas. However, the relative importance of each component of the framework will vary between coastal management initiatives both within the Philippines and across the wider Asian region.Published on line     

The Changing Nature of Conflict and Famine Vulnerability: The Case of Livestock Raiding in Turkana District, Kenya

The context of famine in Turkana has changed in recent years as the role played by livestock raiding in contributing to famine has increased. External responses to famine in Turkana have largely been drought driven, for example, food assistance and livestock restocking programmes, which have failed to meet the real needs of herders. The role of armed conflict in the form of raiding has been overlooked as a common feature of societies facing famine and food insecurity.The traditional livelihood-enhancing functions of livestock raiding are contrasted with the more predatory forms common today. The direct impact of raiding on livelihood security can be devastating, while the threat of raids and measures taken to cope with this uncertainty undermine herders' livelihood strategies. Self-imposed restrictions on mobility negatively affect the vegetation of both grazed and ungrazed pastures and restrict the available survival strategies. Predatory raiding leads to a collapse in the moral economy. Some implications of this for relief and development policy are considered, including approaches to conflict resolution.
