The papers included in this Special Issue address a variety of important aspects of plant biodiversity and genetic resources, including definitions, descriptions, and illustrations of different components and their value for food and nutrition security, breeding, and environmental services. Furthermore, comprehensive information is provided regarding conservation approaches and techniques for plant genetic resources, policy aspects, and results of biological, genetic, morphological, economic, social, and breeding-related research activities. The complexity and vulnerability of (plant) biodiversity and its inherent genetic resources, as an integral part of the contextual ecosystem and the human web of life, are clearly demonstrated in this Special Issue, and for several encountered problems and constraints, possible approaches or solutions are presented to overcome these.

As the United Nations Decade on Biodiversity 2011–2020 comes to a close and countries prepare to adopt a post-2020 global biodiversity framework, this edition of The State of the World’s Forests (SOFO) examines the contributions of forests, and of the people who use and manage them, to the conservation and sustainable use of biodiversity. Forests cover just over 30 percent of the global land area, yet they provide habitat for the vast majority of the terrestrial plant and animal species known to science. Unfortunately, forests and the biodiversity they contain continue to be under threat from actions to convert the land to agriculture or unsustainable levels of exploitation, much of it illegal. The State of the World’s Forests 2020 assesses progress to date in meeting global targets and goals related to forest biodiversity and examines the effectiveness of policies, actions and approaches, in terms of both conservation and sustainable development outcomes. A series of case studies provide examples of innovative practices that combine conservation and sustainable use of forest biodiversity to create balanced solutions for both people and the planet.

Ever wanted to know the genus name for a coconut? Intended for all your research needs, this encyclopedia is a comprehensive collection of information on temperate and tropical fruit and nut crops. Entries are grouped alphabetically by family and then by species, making it easy to find the information you need. Coverage includes palms and cacti as well as vegetable fruits of Solanaceae and Curcurbitacea. This book not only deals with the horticulture of the fruit and nut crops but also discusses the botany, making it a useful tool for anyone from scientists to gardeners and fruit hobbyists.

Thousands of inorganic and organic chemicals and their metabolites enter the biosphere daily as a direct result of human activities. Many of these chemicals have serious consequences on sensitive species of natural resources, crops, livestock, and public health. The most hazardous of these were identified by a panel of environmental specialists from the U.S. Fish and Wildlife Service; these chemicals are the focus of this encyclopedia.For each priority group of chemicals, information is presented on sources, uses, physical and chemical properties, tissue concentrations in field collections and their significance, lethal and sublethal effects under controlled conditions. This includes effects on survival, growth, reproduction, metabolism, carcinogenicity, teratogenicity, and mutagenicity - and proposed regulatory criteria for the protection of sensitive natural resources, crops, livestock, and human health. Taxonomic groups of natural resources covered include terrestrial and aquatic plants and invertebrates, fishes, amphibians, reptiles, birds, and mammals.* The only product that centers on the most hazardous environmental chemicals to sensitive natural resources* The only single volume compendium on the subject, allowing ease in consulting* Written by a noted national and international authority on chemical risk assessment to living organisms

Nut growing has become more popular and technology has developed significantly over the last 5 years. This book is the starting point for prospective commercial nut growers – large or small scale, for farmers who want to diversify and also for gardeners interested in growing nut trees in their back yards. Nut Grower's Guide is the first comprehensive book to growing almonds, cashews, chestnuts, hazelnuts, macadamias, pecans, pistachios and walnuts. All aspects of site selection are covered, from soil and climate to aspect and topography through to previous land use and local pest species. Soil preparation, irrigation, planting and propagating trees are also covered. It covers the cultivation and processing of each of the major nut species and also provides guidance on packaging and the wholesale and retail marketing of nuts in Australia and overseas.

This publication presents a collection of case studies by Mountain Partnership (MP) members from around the world, highlighting experiences of agroecological mountain farming systems. It aims to increase attention toward agroecological principles and approaches and showcase their potential. The MP, the only United Nations global voluntary alliance dedicated to sustainable mountain development, is fully committed to promoting actions that can improve the resilience of mountain people and environments. In mountains, the practice of agroecology and the conservation of agrobiodiversity results in more resilient agricultural and food systems. Sustainable mountain farming systems can drive progress towards reducing rural poverty, contributing to zero hunger, and ensuring the resilience of mountain communities while maintaining the provision of global ecosystem services, especially those related to water. Food security in mountains is a matter of concern. Through adequate and coordinated pro-mountain policies, investments, capacity development, services, and infrastructures, as well as efforts to provide smallholders and family farmers with access to innovation, mountain farming systems have the potential to become pathways for change. In doing so, they can provide valuable support and impetus to the transition to sustainable food systems, contributing to revitalizing rural areas and lifting mountain peoples out of poverty and hunger, while protecting fragile mountain environments for the future.

The Working Group II contribution to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) provides a comprehensive assessment of the scientific literature relevant to climate change impacts, adaptation and vulnerability. The report recognizes the interactions of climate, ecosystems and biodiversity, and human societies, and integrates across the natural, ecological, social and economic sciences. It emphasizes how efforts in adaptation and in reducing greenhouse gas emissions can come together in a process called climate resilient development, which enables a liveable future for biodiversity and humankind. The IPCC is the leading body for assessing climate change science. IPCC reports are produced in comprehensive, objective and transparent ways, ensuring they reflect the full range of views in the scientific literature. Novel elements include focused topical assessments, and an atlas presenting observed climate change impacts and future risks from global to regional scales. Available as Open Access on Cambridge Core.

The Bulletin of the Atomic Scientists is the premier public resource on scientific and technological developments that impact global security. Founded by Manhattan Project Scientists, the Bulletin's iconic "Doomsday Clock" stimulates solutions for a safer world.
