This volume focuses on microscopic plastic debris, also referred to as microplastics, which have been detected in aquatic environments around the globe and have accordingly raised serious concerns. The book explores whether microplastics represent emerging contaminants in freshwater systems, an area that remains underrepresented to date. Given the complexity of the issue, the book covers the current state-of-research on microplastics in rivers and lakes, including analytical aspects, environmental concentrations and sources, modelling approaches, interactions with biota, and ecological implications. To provide a broader perspective, the book also discusses lessons learned from nanomaterials and the implications of plastic debris for regulation, politics, economy, and society. In a research field that is rapidly evolving, it offers a solid overview for environmental chemists, engineers, and toxicologists, as well as water managers and policy-makers.

This open access book is an outcome of the collaboration between the Soil and Water Management & Crop Nutrition Section, Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, Department of Nuclear Sciences and Applications, International Atomic Energy Agency (IAEA), Vienna, Austria, and the International Center for Biosaline Agriculture (ICBA), Dubai, UAE. The objective of this book is to develop protocols for salinity and sodicity assessment and develop mitigation and adaptation measures to use saline and sodic soils sustainably. The focus is on important issues related to salinity and sodicity and to describe these in an easy and user friendly way. The information has been compiled from the latest published literature and from the authors’ publications specific to the subject matter. The book consists of six chapters. Chapter 1 introduces the terms salinity and sodicity and describes various salinity classification systems commonly used around the world. Chapter 2 reviews global distribution of salinization and socioeconomic aspects related to salinity and crop production. Chapters 3 covers comprehensively salinity and sodicity adaptation and mitigation options including physical, chemical, hydrological and biological methods. Chapter 4 discusses the efforts that have been made to demonstrate the development of soil salinity zones under different irrigation systems. Chapter 5 discusses the quality of irrigation water, boron toxicity and relative tolerance to boron, the effects of chlorides on crops. Chapter 6 introduces the role of nuclear techniques in saline agriculture.

This book answers key questions about environment, people and their shared future in deltas. It develops a systematic and holistic approach for policy-orientated analysis for the future of these regions. It does so by focusing on ecosystem services in the world’s largest, most populous and most iconic delta region, that of the Ganges-Brahmaputra delta in Bangladesh. The book covers the conceptual basis, research approaches and challenges, while also providing a methodology for integration across multiple disciplines, offering a potential prototype for assessments of deltas worldwide. Ecosystem Services for Well-Being in Deltas analyses changing ecosystem services in deltas; the health and well-being of people reliant on them; the continued central role of agriculture and fishing; and the implications of aquaculture in such environments.The analysis is brought together in an integrated and accessible way to examine the future of the Ganges Brahmaputra delta based on a near decade of research by a team of the world’s leading scientists on deltas and their human and environmental dimensions. This book is essential reading for students and academics within the fields of Environmental Geography, Sustainable Development and Environmental Policy focused on solving the world’s most critical challenges of balancing humans with their environments.

This open access book examines more than two centuries of societal development using novel historical and statistical approaches. It applies the well-being monitor developed by Statistics Netherlands that has been endorsed by a significant part of the international, statistical community. It features The Netherlands as a case study, which is an especially interesting example; although it was one of the world’s richest countries around 1850, extreme poverty and inequality were significant problems of well-being at the time. Monitors of 1850, 1910, 1970 and 2015 depict the changes in three dimensions of well-being: the quality of life 'here and now', 'later' and 'elsewhere'. The analysis of two centuries shows the solutions to the extreme poverty problem and the appearance of new sustainability problems, especially in domestic and foreign ecological systems. The study also reveals the importance of natural capital: soil, air, water and subsoil resources, showing their relation with the social structure of the ‘here and now´. Treatment and trade of natural resources also impacted on the quality of life ‘later’ and ‘elsewhere.’ Further, the book illustrates the role of natural capital by dividing the capital into three types of raw materials and concomitant material flows: bio-raw materials, mineral and fossil subsoil resources. Additionally, the analysis of the institutional context identifies the key roles of social groups in well-being development. The book ends with an assessment of the solutions and barriers offered by the historical anchoring of the well-being and sustainability issues. This unique analysis of well-being and sustainability and its institutional analysis appeals to historians, statisticians and policy makers.

The aim of the book is to present contributions in theory, policy and practice to the science and policy of sustainable intensification by means of technological and institutional innovations in agriculture. The research insights re from Sub-Saharan Africa and South Asia. The purpose of this book is to be a reference for students, scholars and practitioners inthe field of science and policy for understanding and identifying agricultural productivity growth potentials in marginalized areas.
