Описание: Summarizes the state of biodiversity for food and agriculture in the region, based largely on information provided in fourteen 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.
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.

Описание: These guidelines support a harmonized international approach to assessing the impacts of livestock on biodiversity. The livestock sector is a major user of natural resources (land in particular) and contributor to pollution (causing nutrient losses and increasing greenhouse gas emissions), which makes it a sector with a high impact on biodiversity.

Описание:
Soils with high Ni contents occur in several parts of the world, especially in areas with ultramafic rocks which cause serious environmental impacts. This book aims to extend the knowledge on the risks and problems caused by elevated Ni contents and to cover the existing gaps on issues related to various aspects and consequences of high Ni contents in soils and plants.
Nickel in Soils and Plants brings together discussions on Ni as a trace element and as a micronutrient essential for plant growth and its role in plant physiology. It analyzes the biogeochemistry of Ni at the soil plant interface, and explains its behavior in the rhizosphere resulting in Ni deficiency or toxicity, or Ni tolerance of various Ni hyperaccumulators. Included are Ni resources and sources, the origin of soil Ni, its geochemical forms in soils and their availability to plants, a special reference on soils enriched with geogenic Ni, such as serpentine soils, and the special characteristics of those ecosystems. Recent advancements in methods of Ni speciation, including the macroscale and X- ray absorption spectroscopy studies as well as serious views on Ni kinetics, are also covered.
Written by a team of internationally recognized researchers and expert contributors, this comprehensive work addresses the practical aspects of managing Ni in soils and plants for agricultural production, and managing soils with high Ni levels by using organic and inorganic amendments. The text also addresses practical measures related to Ni toxicity in plants, the removal and recovery of Ni from high Ni wastes, and offers environmentally friendly innovative processes for mining Ni from soils containing high Ni levels.
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.
