Описание: Agroforestry systems (AFS) are becoming increasingly relevant worldwide as society has come to recognize their multiple roles and services: biodiversity conservation, carbon sequestration, adaptation and mitigation of climate change, restoration of degraded ecosystems, and tools for rural development. This book summarizes advances in agroforestry research and practice and raises questions as to the effectiveness of AFS to solve the development and environmental challenges the world presents us today. Currently AFS are considered to be a land use that can achieve a compromise among productive and environmental functions. Apparently, AFS can play a significant role in rural development even in the most challenging socioeconomic and ecological conditions, but still there is a lot of work to do to reach these goals. Considerable funding is spent in projects directed to enhancing productivity and sustainability of smallholders forestry and agroforestry practices. These projects and programs face many questions and challenges related to the integration of traditional knowledge to promote the most suitable systems for each situation; access to markets for AFS products, and scaling up of successful AFS. These complex questions need innovative approaches from varying perspectives and knowledge bases. This book gathers fresh and novel contributions from a set of Yale University researchers and associates who intend to provide alternative and sometimes departing insights into these pressing questions. The book focuses on the functions that AFS can provide when well designed and implemented: their role in rural development as they can improve food security and sovereignty and contribute to provision of energy needs to the smallholders; and their environmental functions: contribution to biodiversity conservation, to increased connectivity of fragmented landscapes, and adaptation and mitigation of climate change. The chapters present conceptual aspects and case studies ranging from traditional to more modern approaches, from tropical as well as from temperate regions of the world, with examples of the AFS functions mentioned above.
Описание: The State of the World's Biodiversity for Food and Agriculture presents the first global assessment of biodiversity for food and agriculture worldwide. Biodiversity for food and agriculture is the diversity of plants, animals and micro-organisms at genetic, species and ecosystem levels, present in and around crop, livestock, forest and aquatic production systems. It is essential to the structure, functions and processes of these systems, to livelihoods and food security, and to the supply of a wide range of ecosystem services. It has been managed or influenced by farmers, livestock keepers, forest dwellers, fish farmers and fisherfolk for hundreds of generations. Prepared through a participatory, country-driven process, the report draws on information from 91 country reports to provide a description of the roles and importance of biodiversity for food and agriculture, the drivers of change affecting it and its current status and trends. It describes the state of efforts to promote the sustainable use and conservation of biodiversity for food and agriculture, including through the development of supporting policies, legal frameworks, institutions and capacities. It concludes with a discussion of needs and challenges in the future management of biodiversity for food and agriculture. The report complements other global assessments prepared under the auspices of the Commission on Genetic Resources for Food and Agriculture, which have focused on the state of genetic resources within particular sectors of food and agriculture.
Описание: The report summarizes the state of biodiversity for food and agriculture in the region, based largely on information provided in ten country reports submitted to FAO as part of the reporting process for the report on The State of the World’s Biodiversity for Food and Agriculture.
The region supports many diverse ecosystems and a high level of biodiversity. The richest and most varied biodiversity tends to be found on high volcanic islands, where there are larger ecosystems and a greater range of habitats. However, the isolation of low-lying islands has often resulted in intense speciation and given rise to levels of endemism that are unique globally. Climate change is threatening the strategic reservoir of genetic resources, while economic and market influences are very strong drivers of change.
The report suggests that overall, knowledge of associated biodiversity (particularly in soils), wild foods and ecosystem functioning is limited, and that all countries agreed that the main constraint in this field is funding. However, the key to optimizing limited resources is to prioritize research needs at national and regional levels. A regional conference on biodiversity for food and agriculture would help in this prioritization process.
Описание: This report summarizes the state of biodiversity for food and agriculture in Africa based on information provided in country reports submitted to FAO as part of the reporting process for The State of the World’s Biodiversity for Food and Agriculture.
The Africa region has a diverse range of production systems, varying from small and mostly mixed systems to large-scale industrial systems. In African smallholder agricultural landscapes, home gardens constitute a particularly important source of biodiversity for food and agriculture and their contribution to plant species richness and diversity is increasingly gaining interest among researchers. Naturally regenerated forests also represent an important repository of biodiversity for food and agriculture.
The report indicates that currently many countries have no policies in place that explicitly address the management of biodiversity for food and agriculture and that associated biodiversity and wild foods tend to be neglected. A number of countries, however, mention more broadly focused instruments, such as national biodiversity strategies and action plans. The report concludes that multidisciplinary, multi-stakeholder consultations in the development of relevant policy and legal instruments need to be strengthened.

Описание: Explores the potential of three forest pathways for achieving green recovery and tackling multidimensional planetary crises, including climate change and biodiversity loss. The interrelated pathways are halting deforestation; restoring degraded lands and expanding agroforestry; and sustainably using forests and building green value chains.
Описание: When first published in 2009, Nature`s Matrix set out a radical new approach to the conservation of biodiversity. This new edition pushes the frontier of the biodiversity/agriculture debate further, making an even stronger case for the need to transform agriculture and support small and medium-scale agroecology and food sovereignty.

Описание: Provides an overview of key elements for developing peatland maps and integrating them into national land use monitoring systems and reporting processes. The report describes the advantages and limitations of different choices and offers practical guidance to facilitate decision-making.
Описание: This report provides an overview of the biological status of assessed stocks around the world and relates measures of stock status to the strength of fisheries management. Stock assessment outputs, consisting primarily of time series of abundance and fishing pressure relative to target reference points, were compiled for 548 marine fish and invertebrate stocks in the RAM Legacy Stock Assessment Database.
Among the data summary methods were global and regional mean trends of abundance and fishing pressure relative to target reference points; bivariate plots of relative abundance and fishing pressure; estimates of potential equilibrium yield foregone at current fishing pressure; and proportions of stocks in different biomass status categories. These measures of stock status were summarized at the global level as well as separated by 16 FAO Major Fishing Areas and ocean basin regions for comparison.
The data presented in this report demonstrated that where fisheries management is being intensely applied (i.e. with regulations based on outputs of scientific stock assessments, and where those regulations are enforced), fishing pressure can be maintained within sustainable ranges that provide maximum or near-maximum long-term yield.
Описание: This study provides an overview of the roles that the biodiversity found in and around food and agricultural production systems play in the supply of ecosystem services. These range from provisioning services, such as the supply of food, fuel and fibre, to cultural services, including recreation and aesthetic enjoyment, and regulating services (e.g. pollination, carbon sequestration, pest control and nutrient cycling).
Biodiversity for Food and Agriculture corresponds to “the variety and variability of animals, plants and micro-organisms at the genetic, species and ecosystem levels that sustain the ecosystem structures, functions and processes in and around production systems, and that provide food and non-food agricultural products.” The study considers a range of ecosystem services across the “provisioning”, “regulating”, “supporting”, “habitat” and “cultural” categories.
The examples presented in the report show that the benefits that a given food and agricultural production unit (i.e. farm, fish farm, forest stand, fishery or livestock holding) gains from biodiversity generally come both from within and from outside the production unit. They also show that the biodiversity present in and around food and agricultural production systems often provides ecosystem services whose benefits are felt far beyond the food and agriculture sector (and in some cases far away in geographical terms).
Описание: 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.
