Following up on previous reports prepared for the Commission on Genetic Resources for Food and Agriculture, and acknowledging FAO’s long tradition of technical work on the management of microorganisms and invertebrates in food and agriculture, the present paper responds to the need for a detailed assessment of the state of art in the conservation and sustainable use of soil microorganisms and invertebrates. It focuses on microorganisms and invertebrates contributing to nutrient cycling and the removal of contaminants from soils. The study is based on an extensive literature review and summarizes current views on the taxonomy, conservation, use and exchange of soil microorganisms and invertebrates, highlighting knowledge gaps, needs and challenges. In order to encompass the views of a wide range of stakeholders on knowledge gaps and critical issues related to the conservation and sustainable use of these organisms, the Austrian Institute of Technology (AIT) circulated an invitation to complete an open online survey to several hundred researchers, institutions and organizations worldwide. Twenty-seven responses were received and evaluated. AIT also organized an online expert workshop entitled Status and Trends of Conservation of Soil Microorganisms and Invertebrates, with Emphasis on Bioremediation and Nutrient Cycling Organisms. Twenty-six international experts participated in three parallel sessions: (i) nutrient cycling in soil; (ii) bioremediation in food and agriculture systems; and (iii) conservation of microorganisms and invertebrates, practices, policies and needs. The issues raised in the survey responses and at the workshop were taken into account in the drafting of the study.

The Flexible Voluntary Contribution (FVC) 2022 annual progress report captures the key achievements of the FVC, both in terms of its role as a pooled fund for non-earmarked and softly earmarked contributions from resource partners and the implementation of development initiatives through FVC subprogrammes. The report provides a comprehensive understanding of the FVC's role within the Organization, the contribution of FVC-funded work to the achievements of FAO's four betters and their respective Programme Priority Areas (PPAs), and the future direction of the FVC based on experiences in 2022. The report comprises six sections: (1) Introduction, (2) Achievements of the FVC as a fund, (3) Achievements of FVC programmes (the four betters), (4) Key FVC principles, (5) Challenges and lessons learned, and (6) Conclusions and future actions.

We are not free from environmental risks that accompany the development of human societies. Modern economic development has accelerated environmental pollution, caused loss of natural habitats, and modified landscapes. These environmental changes have impacted natural systems: water and heat circulation, nutrient cycling, and biodiversity. These changes in natural systems degrade ecosystem services and subsequently increase environmental risks for humans. Environmental risks, therefore, are not only human health risks by pollution, climatic anomalies and natural disasters, but also degradation of ecosystem services on which most people are relying for their lives. We cannot entirely eliminate the risks, because it is not possible to attain zero impact on the environment, but we need to find a mechanism that minimizes environmental risks for human sustainably. This is the idea of the interdisciplinary framework of “environmental risk management” theory, which advocates harmony between economic development and environmental conservation. Based on this theory, the Sustainable Living with Environmental Risk (SLER) programme, adopted by the Japanese Ministry of Education (MEXT) as one of its strategic programmes, has been training graduate students at the Yokohama National University, Japan, from 2009 to 2013 to become future environmental leaders who will take the initiative in reducing the level of environmental risks and in protecting natural resources in the developing nations of Asia and Africa. This book provides students and teachers of this new academic field with a comprehensive coverage of case studies of environmental risks and their practical management technologies not only in Japan but also in developing nations in Asia and Africa.

Written by leading experts in their respective fields, Principles and Applications of Soil Microbiology 3e, provides a comprehensive, balanced introduction to soil microbiology, and captures the rapid advances in the field such as recent discoveries regarding habitats and organisms, microbially mediated transformations, and applied environmental topics. Carefully edited for ease of reading, it aids users by providing an excellent multi-authored reference, the type of book that is continually used in the field. Background information is provided in the first part of the book for ease of comprehension. The following chapters then describe such fundamental topics as soil environment and microbial processes, microbial groups and their interactions, and thoroughly addresses critical nutrient cycles and important environmental and agricultural applications. An excellent textbook and desk reference, Principles and Applications of Soil Microbiology, 3e, provides readers with broad, foundational coverage of the vast array of microorganisms that live in soil and the major biogeochemical processes they control. Soil scientists, environmental scientists, and others, including soil health and conservation specialists, will find this material invaluable for understanding the amazingly diverse world of soil microbiology, managing agricultural and environmental systems, and formulating environmental policy. - Includes discussion of major microbial methods, embedded within topical chapters - Includes information boxes and case studies throughout the text to illustrate major concepts and connect fundamental knowledge with potential applications - Study questions at the end of each chapter allow readers to evaluate their understanding of the materials

This compilation has been designed to provide a comprehensive source of theoretical and practical update for scientists working in the broad field of soil science. The book explores all possible mechanisms and means to improve nutrient use efficiencies involving developing and testing of nanofertilizers, developing consortia based microbial formulations for mobilization of soil nutrients, and engineering of nutrient efficient crops using molecular biology and biotechnological tools. This is an all-inclusive collection of information about soil science. This book is of interest to teachers, researchers, soil scientists, capacity builders and policymakers. Also the book serves as additional reading material for undergraduate and graduate students of soil science, quantitative ecology, earth sciences, GIS and geodetic sciences, as well as geologists, geomorphologists, hydrologists and landscape ecology. National and international agriculture and soil scientists, policy makers will also find this to be a useful read.

This book includes twenty-one comprehensive chapters addressing various soil and crop management issues, including modern techniques in enhancing crop production in the era of climate change. There are a few case studies and experimental evidence about these production systems in specific locations. Particular focus is provided on the state-of-the-art of biotechnology, nanotechnology, and precision agriculture, as well as many other recent approaches in ensuring sustainable crop production. This book is useful for undergraduate and graduate students, teachers, and researchers, particularly in the fields of crop science, soil science, and agronomy.
