Book Description
It is only recently that the immense economic value of pollination to agriculture has been appreciated. At the same time, the alarming collapse in populations of bees and other pollinators has highlighted the urgency of addressing this issue. This book focuses on the specific measures and practices that the emerging science of pollination ecology is identifying to conserve and promote animal pollinators in agroecosystems. It reviews the expanding knowledge base on pollination services, providing evidence to document the status, trends and importance of pollinators to sustainable agricultural production. It provides practical and specific measures that land managers can undertake to ensure that agroecosystems are supportive and friendly to pollinators. It draws on the Global Pollination Project, supported by UNEP/GEF and implemented by FAO and seven partner countries (Brazil, Ghana, India, Kenya, Nepal, Pakistan and South Africa), which serve to provide "lessons from the field".

Book Description
Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

Book Description
Most flowering plants, including wild species and many food crops, are pollinated by animals and are vital, therefore, for biological production and the maintenance of biodiversity. Pollinators benefit from diverse natural habitats for forage and nesting, especially when these are limited in plant production systems. Landscape and forest management practices can help ensure the continued availability of pollinators and thereby increase resilience and the productivity of forestry and agriculture. The extent of forests and other natural habitats in a landscape plays a role in determining the species composition of pollinators. Agricultural landscapes adjoining fragmented forests and natural areas benefit from pollinator services, and animal-pollinated crops therefore achieve higher fruit set. Forest management practices can have significant effects on pollinator abundance and diversity. They affect forest variables such as structure, species composition, soil dynamics, hydrology and light availability, all of which can affect pollinator species composition and diversity and plant–pollinator networks. Indigenous and local knowledge can contribute to the conservation of pollinators through traditional management practices. This working paper, which is aimed at forest practitioners, landscape planners and land-use decision-makers, reviews published literature on the impacts of forest and landscape management practices on pollinators. It also addresses the implications of climate change, collates 36 case studies, and makes recommendation on measures for maintaining pollinator diversity and abundance in forests and landscapes

Book Description
Organic animal production has increased rapidly in recent years to keep up with the increasing consumer demand for organic meats. There are many guidelines and restrictions on what should go into the feedstuffs of organically farmed animals, from which difficulties arise when trying to ensure a well-balanced, nutritious diet without the use of any supplements. The book has been completely updated and revised to address how to formulate organic diets in situations where there is a declining supply of organic feed, as well as the feasibility of utilizing novel feedstuffs and their acceptability by consumers of organic meat products. Including the experiences of producers in relation to appropriate breeds and production systems for forage-based organic production, this book is an important read for researchers and students of organic food animal production, veterinary sciences and food; as well as food industry personnel and organic farmers.

Book Description
This study takes a broad and timely approach to animal movement across both temporal and spatial scales. Movement and migration on land, in the air, and in water are pervading features of animal life-from the smallest protozoans to the largest whales - and can extend from millimetres to global scale. Research into animal movement ecology is now entering a new era with the development of novel molecular, electronic, and technical methods that make it possible to analyse the movements of individual animals under complex environmental conditions that determine the evolution of movement habits.

Book Description
The collapse of the ubiquitous honeybee population during the past 20 years has caused a pollination vacuum for many crops. Surveys and grower experience indicate that a crisis exists in our pollinator populations. This book is an accessible, practical and authoritative research-based guide to using bees for crop pollination. It emphasizes conserving feral bee populations as well as more traditional methods of culturing honeybees and other bees. There are three main sections that address the biology of pollination, culturing and managing bees for optimum crop pollination, and individual crop pollination requirements and recommendations. This last section includes 42 short chapters on different crops.

Book Description
As the discipline of pollination ecology moves from describing the extent of a pollinator crisis, to identifying what can be done about it, there is a need to share and highlight very practical measures that will support sustainable crop biotic pollination services. Identifying these practices will require a mix of farmer and natural historian knowledge and scientific research. In this publication, we will outline the practices that have been so far identified, and what experiences may contribute to sharing the effectiveness of these measures under different circumstances.

Book Description
"This publication provides guidance on the natural history of wild bees and their potential exposure to pesticides, as part of the GEF supported Project "Conservation and Management of Pollinators for Sustainable Agricutlure, through an Ecosystem Approach" implemented in seven countries -- Brazil, Ghana, India, Kenya, Nepal, Pakistan and South Africa. The project is coordinated by the Food and Agriculture Organization of the United Nations (FAO) with implementation support from the United Nations Environment Programme (UNEP)"--Title page verso, page [ii].
