Book (series)Flagship世界粮食和农业领域土地及水资源状况
濒危系统的管理
2011到2050年,全球范围内的粮食产量预计需要再递增70%左右,而在发展中国家这一比例将近100%。面对粮食增产的这一需求,再加上其他领域需求的争夺,使全球许多农业生产系统纷纷置于前所未有的压力之下。这些“濒临系统”正处于愈演愈烈的水土资源大战之中,而且还经常受到不可持续的农耕方式的掣肘。因此,需要对其特别注意并采取具体的救助措施。《世界粮食和农业领域土地及水资源状况》(SOLAW)就这些高危领域如何克服制约因素并改善资源管理探讨了多种方案。在每一个领域,除了要在制度和政策上作出一些列调整外,还必须将其与扩大技术应用结合起来,以获得更好的水土资源管理效果。另外,加大投资力度、提供新型融资机制以及开展国际合作与开发援助也有助于克服这些制约因素。本书作为《世界粮食和农业领域土地及水资源状况》第一期,是对联合国粮食及农业组织出版的其他“世界状况”类报告的一个补充,其旨在揭示国家与国际层面上的论争和决策情况。 -
Book (stand-alone)Flagship世界粮食和农业领域土地及水资源状况:系统濒临极限
2021年概要报告
2021满足日益增长的粮食需求在世界范围内给水、土地和土壤资源造成压力。农业可为减轻这些压力贡献力量,助力实现气候和发展目标。可持续农业模式能够直接改善土地、土壤和水资源状况,产生生态系统惠益,减少土地来源的排放。实现上述目标需要精准的信息,更需要我们大刀阔斧地改革资源管理模式;此外还需要自然资源管理范畴之外的补充力量,以便协同增效,权衡取舍。2021年版《世界粮食和农业土地及水资源状况》旨在介绍土地和水资源现状,着重指出风险,梳理相关机遇和挑战。此外,报告还强调了适当政策、机制与投资的重要作用。近期开展的评估、预测和情境分析表明,水土资源消耗加速,生物多样性损失愈加严峻。2021年版报告着重分析了土地、土壤和水资源的相关风险和发展趋势,提出了解决用户竞争、实现预期惠益的途径。报告介绍了最新的知识内容,提出了一整套应对措施和行动,可以帮助决策者做出合理决策,推动由退化和脆弱转向可持续和韧性发展。

Book (series)Technical studyPacific oyster farming
A practical manual
2024Also available in:
No results found.The purpose of this manual is to give the reader a foundation of practical knowledge regarding all aspects of Pacific oyster cultivation. It is targeted at new entrants to the market wishing to establish a farm, and existing operators who wish to develop their farms and explore new cultivation techniques. The methodologies described can be applied both to low-tech, low budget, small-scale farming operations and to high-tech, big budget, industrial-scale aquaculture production enterprises. This guide focuses on the functional expertise and technical equipment required to construct and manage an operational farm in the diverse environmental and physical locations in which they can be situated, from the initial stages of finding and selecting a suitable site, to the conclusion of the first production cycle and harvesting the crop. The manual contains a brief introduction which describes the relevance of the species with regards to global aquaculture production figures and how it can form an important part of future food production strategies. Chapter 2 describes the anatomy and biology of Crassostrea gigas and gives an indication as to the environmental conditions in which the species thrives as well as the pathologies and predators that can result in poor health leading to potential mortalities. Chapter 3 deals with all aspects of undertaking a survey of potential oyster farming sites and what data should be collected and examined to assess a site’s suitability, but also which areas are best suited to different cultivation techniques. After this, Chapter 4 introduces the main farming techniques that will be described in detail in the following chapters, which includes off-bottom cultivation, on-bottom cultivation, and suspended cultivation, and gives details of some of the most common cultivation equipment necessary to undertake these operations. The techniques and strategies necessary to procure seed oysters and how to develop them through the nursery stage are also introduced. This includes the basic principles of upwelling, which then leads into Chapter 5, which provides a detailed description of how to build and operate one particular example of a Floating Upwelling System (Flupsy) which is suitable for use in remote but sheltered conditions. Chapters 6, 7 and 8 constitute the main body of the manual and provide an in-depth look into the three major cultivation techniques that this guide concentrates on: “Farming with trestles and bags in the intertidal zone”, “On-bottom cultivation in the intertidal or subtidal zone” and “Offshore longline cultivation”. -
