Large quantities of water are appropriated to produce the feed annually consumed in global livestock production. Rising concerns about increasing competition for water resources and projected increase in demand for livestock products make it imperative to look for strategies to sustainably increase livestock production, with water being one key natural resource to consider. Using a combination of different datasets, a mechanistic livestock model, and a dynamic vegetation model, we estimate the annual consumptive water use (CWU) in the global livestock sector associated with crops and fodder cultivated on cropland and grazed biomass from pastures.

Originating from the work of the late Nobel laureate Ilya Prigogine, ECOSUD 2017 was the 11th International Conference on Ecosystems and Sustainable Development in this long-standing series. This volume contains papers presented at the meeting and covers new research on ecological problems, as well as new ideas and concepts from scientists, engineers, socio-economic specialists and other professionals working in this area. Emphasis is placed on subject areas that would benefit from the application of scientific methods for sustainable development, including the conservation of natural systems around the world whilst also integrating thermodynamics, ecology and economics. Furthermore, the study of distributed systems is addressed in order to avoid transport recovery and waste reduction. Individual topics covered include: Energy systems and the environment; Sustainable development and planning; Ecosystem modelling; Environmental innovative approaches; Natural resources management; Protection and mitigation; Knowledge dissemination; Social responsibility; Sustainability indicators, monitoring and assessment; Urban agriculture; Environmental risk management; Ecosystems recovery; Complex systems in ecology; Ecosystems networks; Biomass issues; Integrated assessment tools.

Papers presented at the 2nd International Conference on Coastal Cities and their Sustainable Future are contained in this volume. Since its successful introduction in 2015 the conference has continued to attract important research covering the integrated management and sustainable development of coastal cities. An increased world population and the preference for living in coastal regions has resulted in their ever-growing expansion. Whilst this creates economic growth, it also increases the need for improved resources, infrastructure and services. Coastal cities should be considered as dynamic complex systems which need energy, water, food and other resources in order to work and produce diverse activities, with the aim of offering a socioeconomic climate and improved quality of life. Consequently the integrated management and sustainable development of coastal cities is essential with science, technology, architecture, socio-economics and planning all collaborating to support decision makers. Planners need to explore various options and models to forecast future services, plans and solutions. Included papers examine some of these possible models and potential solutions with emphasis in the areas of: Landscape and urban planning; Infrastructures and eco-architecture; City heritage and regeneration; Urban transport and communications; Commercial ports; Fishing and sports harbours; City-Waterfront interaction; Marine industries; Water resources management; Quality of life and city leisure; Tourism and the city; Water pollution; Air pollution; City waste management; Acoustical and thermal pollution; Coastal risk assessment; Coastal flooding; Coastal processes; Landslides; Socio-economic issues.

Irrigation is becoming an activity of precision, where combining information collected from various sources is necessary to optimally manage resources. New management strategies, such as big data techniques, sensors, artificial intelligence, unmanned aerial vehicles (UAV), and new technologies in general, are becoming more relevant every day. As such, modeling techniques, both at the water distribution network and the farm levels, will be essential to gather information from various sources and offer useful recommendations for decision-making processes. In this book, 10 high quality papers were selected that cover a wide range of issues that are relevant to the different aspects related to irrigation management: water source and distribution network, plot irrigation systems, and crop water management.

The bioeconomy concept aims to add sustainability to the production, transformation, and trade of biological goods. Though implemented around the world, the development of national bioeconomies is uneven, especially in the global South, where major challenges exist in Sub-Saharan Africa. In this context, the international BiomassWeb project aimed to underpin the bioeconomy concept by applying the value web approach, which seeks to uncover complex interlinked value webs instead of linear value chains. The project also aimed to develop intervention options to strengthen and optimize the synergies and trade-offs among different value chains. The Special Issue “Advances in Food and Non-Food Biomass Production, Processing and Use in Sub-Saharan Africa: Toward a Basis for a Regional Bioeconomy" compiles 23 articles produced in this framework. The articles are grouped in four sections: the value web approach; the production side; processing, transformation and trade; and global views.

This book contributes to the multidisciplinary debate about social–ecological systems (SES) within the perspective of rethinking the nature of interaction between these systems, especially in the Anthropocene Era. Most chapters either deliberate on risk dynamics threatening current SES or stimulate thought processes to manage such risks and related negative implications. After analyzing the main drivers of SES vulnerability, the book highlights the shifts to be made to enhance the sustainability and resilience of these systems, mainly the integration and restructuring of governance frameworks, the reorganization of production and consumption systems far from conventional models based on consumerism, the elaboration of mitigation, adaptation, and SDGs implementation measures from a co-benefit perspective, and the consideration of appropriate approaches and paradigms while elaborating and implementing response mechanisms. This volume is relevant to researchers/experts, students, practitioners, and decision-makers from different scales and spheres.

Plants are subjected to a variety of abiotic stresses such as drought, temperature, salinity, air pollution, heavy metals, UV radiations, etc. To survive under these harsh conditions plants are equipped with different resistance mechanisms which vary from species to species. Due to the environmental fluctuations agricultural and horticultural crops are often exposed to different environmental stresses leading to decreased yield and problems in the growth and development of the crops. Drought stress has been found to decrease the yield to an alarming rate of some important crops throughout the globe. During last few decades, lots of physiological and molecular works have been conducted under water stress in crop plants. Water Stress and Crop Plants: A Sustainable Approach presents an up-to-date in-depth coverage of drought and flooding stress in plants, including the types, causes and consequences on plant growth and development. It discusses the physiobiochemical, molecular and omic approaches, and responses of crop plants towards water stress. Topics include nutritional stress, oxidative stress, hormonal regulation, transgenic approaches, mitigation of water stress, approaches to sustainability, and modern tools and techniques to alleviate the water stress on crop yields. This practical book offers pragmatic guidance for scientists and researchers in plant biology, and agribusinesses and biotechnology companies dealing with agronomy and environment, to mitigate the negative effects of stress and improve yield under stress. The broad coverage also makes this a valuable guide enabling students to understand the physiological, biochemical, and molecular mechanisms of environmental stress in plants.

Rising levels of global inequality and migrant flows are both critical global challenges. Set within the Southeast Asian nation of Cambodia, Going Nowhere Fast sets out to answer a question of global importance: how does inequality persist in our increasingly mobile world? Inequality is often referred to as the greatest threat to democracy, society, and economy, and yet opportunity has apparently never been more accessible. Long and short distance transport - from motorbikes to aeroplanes - are available to more people than ever before and telecommunications have transformed our lives, ushering in an era of translocality in which the behaviour of people and communities is influenced from hundreds or even thousands of miles apart. Yet amidst these complex flows of people, ideas, and capital, persistent inequality cuts a jarringly static figure. Going Nowhere Fast brings together a decade of research to examine this uneven development in Cambodia, making a case for inequality as a 'total social fact' rather than an economic phenomenon, in which stories, stigma, obligation and assets combine to lock social structures in place. Going Nowhere Fast: Inequality in the Age of Translocality speaks from an in-depth perspective to an issue of global relevance: how inequality persists in our hypermobile world. Focusing on pressing issues in Cambodia that resonate beyond, it investigates how human movement within and across the nation's borders are intertwined with societal threats and challenges, including of precarious labour and agricultural livelihoods; climate and environmental change; the phenomenon of land grabbing; and the rise of popular nationalism.
