Book Description
During the last decades, soil organic carbon (SOC) attracted the attention of a much wider array of specialists beyond agriculture and soil science, as it was proven to be one of the most crucial components of the earth’s climate system, which has a great potential to be managed by humans. Soils as a carbon pool are one of the key factors in several Sustainable Development Goals, in particular Goal 15, “Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification and halt and reverse land degradation and halt biodiversity loss” with the SOC stock being explicitly cited in Indicator 15.3.1. This technical manual is the first attempt to gather, in a standardized format, the existing data on the impacts of the main soil management practices on SOC content in a wide array of environments, including the advantages, drawbacks, and constraints. This manual presents different sustainable soil management (SSM) practices at different scales and in different contexts, supported by case studies that have been shown with quantitative data to have a positive effect on SOC stocks and successful experiences of SOC sequestration in practical field applications. Volume 2 includes a description of hot spots of SOC stocks. This manual defines hot spots of SOC as areas that represent a proportionally little of the global land surface but on which SOC storage is highly effective; bright spots as large land areas with low SOC stocks per km2 that represent a potential for further carbon sequestration.

Book Description
Predictive Soil Mapping (PSM) is based on applying statistical and/or machine learning techniques to fit models for the purpose of producing spatial and/or spatiotemporal predictions of soil variables i.e. maps of soil properties and classes at different resolutions. It is a multidisciplinary field combining statistics, data science, soil science, physical geography, remote sensing, geoinformation science and a number of other sciences. Predictive Soil Mapping with R is about understanding the main concepts behind soil mapping, mastering R packages that can be used to produce high quality soil maps, and about optimizing all processes involved so that also the production costs can be reduced. The online version of the book is available at: https: //envirometrix.github.io/PredictiveSoilMapping/ Pull requests and general comments are welcome. These materials are based on technical tutorials initially developed by the ISRIC's Global Soil Information Facilities (GSIF) development team over the period 2014-2017

Book Description
Rebuilding soil organic matter (SOM) to regionally specific targets for high quality soil that are likely maintained in the long term, here defined as “SOM JumpStart”, can unlock soil's potential for increased productivity, enhanced resilience and reduced emission as the main components for climate-smart agriculture (CSA). A field experiment was established in 2013 at Fulton County, western Illinois to use highly stabilized organic amendment (HSOA) at a rate, potentially raising surface SOM of cultivated Alfisol (low quality soil) to the level of cultivated Mollisol (high quality soil for US Midwest). Treatments included one-time application of lagoon-aged air-dried biosolids at 165 Mg ha-1, one-time application of vegetative compost at 165 Mg ha-1, chemical fertilizer at 225-50-85 kg ha-1 yr-1 (N-P-K) as control, and grass fallow as reference. In every year following the HSOA application, fertilizer (N and K) rate was reduced by 25%, and no P was applied for most years. Corn was planted annually. The HSOA JumpStart application dramatically increased SOM, leading to soil organic carbon (SOC) at 2-2.5% after biosolids and about 3% after compost for 2013-2019, as that of Mollisol, while that in chemical fertilizer control remained unchanged at 1-1.2%. For the first seven years, HSOA JumpStart increased corn grain yield by a mean of 19.8% (biosolids) and 7.1% (compost) above the control, with greater increase at precipitations-abnormal (low/high) years. The SOM JumpStart caused the shift of soil microbial physiology to high C utilization efficiency, as evident by reduced microbial metabolic quotient for CO2, leading to the decrease in CO2 emission from agricultural crop residues by 19.6% (biosolids) and 20.0% (compost). Our modeling revealed the promising soil C sequestration (excluding residual C from HSOA) over next 50 years at 10.6 Mg C ha-1 by biosolids application and 13.9 Mg C ha-1 by compost application, higher than 6.8 Mg C ha-1 anticipated by “4 per 1000” international initiative. Even 50 years later, total SOC stock in JumpStarted soil is expected to be over 50% higher than that in control. Our results suggest the SOM JumpStart by HSOA such as biosolids and compost can transform conventional corn production to CSA.

Book Description
Few topics cut across the soil science discipline wider than research on soil carbon. This book contains 48 chapters that focus on novel and exciting aspects of soil carbon research from all over the world. It includes review papers by global leaders in soil carbon research, and the book ends with a list and discussion of global soil carbon research priorities. Chapters are loosely grouped in four sections: § Soil carbon in space and time § Soil carbon properties and processes § Soil use and carbon management § Soil carbon and the environment A wide variety of topics is included: soil carbon modelling, measurement, monitoring, microbial dynamics, soil carbon management and 12 chapters focus on national or regional soil carbon stock assessments. The book provides up-to-date information for researchers interested in soil carbon in relation to climate change and to researchers that are interested in soil carbon for the maintenance of soil quality and fertility. Papers in this book were presented at the IUSS Global Soil C Conference that was held at the University of Wisconsin-Madison, USA.

Book Description
This book presents an important discussion on urbanization and sustainable soil management from a range of perspectives, addressing key topics such as sustainable cities, soil sealing, rehabilitation of contaminated soils, property rights and liability issues, as well as trading systems with regard to land take. This third volume of the International Yearbook of Soil Law and Policy is divided into four parts, the first of which explores several aspects of the topic “urbanization and sustainable management of soils.” The second part then covers recent international developments, while the third part presents regional and national reports, and the fourth discusses cross-cutting issues. Given the range of key topics covered, the book offers an indispensible tool for all academics, legislators and policymakers working in this field. The “International Yearbook of Soil Law and Policy” series discusses central questions in law and politics with regard to the protection and sustainable management of soil and land – at the international, national and regional level.

Book Description
Many national legal frameworks still do not include laws and measures specifically intended to tackle climate change in the agriculture sectors. However, national laws and institutional frameworks are necessary for good governance and can operate to support the implementation of national policy and international commitments, including on climate change. Indeed, Target 16.3 of the Sustainable Development Goals calls for the promotion of the rule of law, and the assurance of equal access to justice for all. This is both an important stand-alone goal and an enabling goal for the realization of the transformative 2030 Agenda for Sustainable Development‎. Furthermore, the Food and Agriculture Organization of the United Nations (FAO) sees appropriately designed, informed and responsive national legal and institutional frameworks as key to supporting the implementation of countries’ commitments under the 2015 Paris Agreement, as well as their Nationally Determined Contribution in the food, agriculture and natural resources sectors. Climate change presents multiple challenges and it cannot be addressed effectively in silos. Attention must be paid not only to specific agriculture sectors, but also to governance areas that are interconnected with agriculture, such as public spending and investment, social protection and rural development. Efforts should be coordinated with the engagement of civil society, including the legal profession, vulnerable groups and the private sector.This Study addresses the principal expressions of the food and agriculture sector (crops and livestock agriculture, forestry and fisheries), looking at the critical cross-cutting issues and their integration into agriculture law. It provides a comprehensive overview of the legal and institutional issues to consider when working towards preparing the agriculture sector for the challenges of climate change.

Book Description
Despite significant progress in increasing agricultural production, meeting the changing dietary preferences and increasing food demands of future populations remains a significant challenge. Salinity, drought, water logging, high temperature and toxicity are abiotic stresses that affect the crop yield and production. Tolerance for stress is a important characteristic that plants need to have in order to survive. Identification of proper techniques at a proper time can make it easy for scientists to increase crop productivity and yield. In Engineering Tolerance in Crop Plants against Abiotic Stress we have discussed the possible stresses and their impact on crops and portrayed distinctive abiotic stress tolerance in response to different techniques that can improve the performance of crops. Features of the Book: Provide a state-of-the-art description of the physiological, biochemical, and molecular status of the understanding of abiotic stress in plants. Address factors that threaten future food production and provide potential solution to these factors. Designed to cater to the needs of the students engaged in the field of environmental sciences, soil sciences, agricultural microbiology, plant pathology, and agronomy. New strategies for better crop productivity and yield. Understanding new techniques pointed out in this book will open the possibility of genetic engineering in crop plants with the concomitant improved stress tolerance.
