No results found.In this paper, we explore the nature of several key drivers of change in food systems, and examine a number possible entry points for policy intervention, in order to determine their effect on food prices and other marketdriven outcomes. Among the drivers of change that we discuss are those of policy-driven growth in biofuel production, which has had a role to play in the rapid increase in food prices, along with other factors. We demonstrate the off-setting impact that supply growth cou ld have on the socio-economic impacts of biofuels, both in terms of price changes, as well as changes in nutrition status. We also look at some evidence that points towards the significant impact that climate change could have on the agriculture and agricultural prices in the future. Combining our quantitative experiments with cited evidence from other studies, we suggest a range of policy interventions that could be instrumental in offsetting the negative impacts of food prices, and hel ping to promote those benefits in situations where they might exist. Among these suggestions, we encourage increased investments in the agricultural sector, so as to reverse the steadily declining growth of research and development spending and change decades of counter-productive agricultural trade and national-level sector policies. -

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”. -
Book (stand-alone)General interest bookВопросы лесного хозяйства и агролесоводства в национальных планах адаптации
Вспомогательные руководящие принципы
2023Данная публикация «Вопросы лесного хозяйства и агролесоводства в национальных планах адаптации: вспомогательные руководящие принципы» представляет собой техническое руководство по интеграции лесов, агролесоводства и деревьев в процесс разработки и реализации НПА. Его цель – информировать разработчиков политики и государственных служащих, ответственных за планирование и процессы в рамках НПА, а также субъектов деятельности в области лесного хозяйства и других заинтересованных сторон о потребностях лесного хозяйства и агролесоводства для адаптации и их потенциале для поддержки адаптации других отраслей, подотраслей и видов деятельности. -
