Water in California is controlled, stored, delivered, and managed within a complex network of interlocking and cooperating districts and agencies. Unraveling and understanding this system is not easy. This book describes how the current system works (or doesn't work) and discusses the issues that face elected officials, water and resource managers, and the general public. Using the Los Angeles area as a microcosm of the state, environmental activist Dorothy Green gathers detailed information on its water systems and applies the lessons learned from this data statewide. A useful primer on watershed and water policy issues, this book provides reasoned, thoughtful, and insightful arguments about sustainability.

Agriculture is certainly the most important food supplier while it globally accounts for more than 70% of water used and contributes significantly to water pollution. Irrigated agriculture is facing rising competition worldwide for access to reliable, low cost, and high-quality water resources. However, irrigation as the major tool and determinant of affecting agricultural productivity and environmental resources plays a critical role in food security and environment sustainability. Innovative irrigation technologies and practices may enhance agricultural water efficiency and production, in the meantime decrease the water demand and quality issues. I am very pleased to invite you to submit manuscripts in agricultural irrigation which assess current challenges and offer improvement approaches and opportunities for future irrigation.

This book is focused on the existing gap between the theoretical bioactivity of (poly)phenols and their real influence in terms of health, once ingested. Due to this, new studies are needed and some examples of new tendencies are included from in vitro and in vivo models which allow for exploring bioaccessibility, bioavailability, and bioactivity, that need to be developed to understand the actual importance of consuming functional foods, rich in these plant secondary metabolites. Moreover, current new strategies need to be developed to enhance the content of these foods, as well as setting up new formulations rich in bioaccessible and bioavailable compounds. Altogether, it could provide a new perspective in therapy, expanding the use of these natural functional compounds, ingredients, and foods in the clinical frame, reducing the use of synthetic drugs. As a result, the joint contribution of multidisciplinary experts from the areas of food science, health, and nutrition, together with the industrial sector, would help to reach these objectives. Taking this into account, diverse studies have been included in this study, which comprises different strategies to approach these objectives from different, complementary, points of view, ranging from the enrichment of by-products in bioactive compounds, through different agricultural techniques, to the assimilation of these compounds by the human body, both in vitro and in vivo, as well as by clinical studies.

This Special Issue opens a new field of research in certain emerging innovative instruments, because it provides an in-depth revision of the main aspects of institutions and instruments available for the management and governance of droughts and water scarcity. The key aspects that institutions may tackle not only include the increasing water scarcity in many regions around the world but also the increasing frequency and impact of droughts on economic and natural systems. Some of the included papers analyze critical issues, such as the state and future trends of water markets; the estimation of transaction costs when dealing with drought management; and the use of new instruments, such as insurance and water-rights entitlements, which include water security, water-pricing effects on the whole basin level, and intra- and inter-sectorial re-allocation. The important issues regarding non-conventional water supply and the governance of the new resources also feature as the focus of some of the contributions.

Vegetables are an important part of the human diet due to their nutrient density and, at the same time, low calorie content. Producers of vegetable crops mainly aim at achieving high yields with good external quality. However, there is an increasing demand of consumers for vegetables that provide good sensory properties and are rich in secondary compounds that can be valuable for human health. Sub- or supra-optimal abiotic conditions, like high temperatures, drought, excess light, salinity or nutrient deficiency, may alter the composition of vegetable crops and at the same time, result in yield loss. Thus, producers need to adapt their horticultural practices such as through the choice of variety, irrigation regime, light management, fruit thinning, or fertilizer application to improve the yield and quality of the vegetable product. In the future, altered climate conditions such as elevated atmospheric CO2 concentrations, rising temperatures, or altered precipitation patterns may become additional challenges for producers of vegetable crops, especially those that cultivate in the open field. This raises the need for optimized horticultural practices in order to minimize abiotic stresses. As well, specific storage conditions can have large impacts on the quality of vegetables. This Special Issue compiles research that deals with the optimization of vegetable product quality (e.g. sensory aspects, composition) under sub- or supra-optimal abiotic conditions.

The evaluation of the water footprint and virtual water trade has become a promising means to evaluate the sustainability of a country’s water resources. This book is based on the research and results of a thorough study carried out for Spain, which serves as a leading case for a semi-arid country. The objective of this study was to assess and analyze Spain’s virtual water use and water footprint, differentiating the green and blue (surface and groundwater) components, both from a hydrological and economic perspective. This contributes to the water footprint and virtual water literature in several ways. By evaluating both water footprint and virtual water over time and at the provincial scale, the analysis allows for policy-relevant conclusions at the river basin level. By separating green and blue water components, and evaluating all crops at the provincial level, the study enables a finer analysis of how water footprint and virtual water vary during droughts and water shortages. The linkage between commodities trade and water scarcity was explored to determine the extent to which virtual water trade has the potential to deal with water-stressed periods. The analysis contained in this study includes both market and non-market dimensions and will appeal to researchers in both resource economics and hydrology as well as policy-makers concerned with water-related issues.

Land surface phenology (LSP) uses remote sensing to monitor seasonal dynamics in vegetated land surfaces and retrieve phenological metrics (transition dates, rate of change, annual integrals, etc.). LSP has developed rapidly in the last few decades. Both regional and global LSP products have been routinely generated and play prominent roles in modeling crop yield, ecological surveillance, identifying invasive species, modeling the terrestrial biosphere, and assessing impacts on urban and natural ecosystems. Recent advances in field and spaceborne sensor technologies, as well as data fusion techniques, have enabled novel LSP retrieval algorithms that refine retrievals at even higher spatiotemporal resolutions, providing new insights into ecosystem dynamics. Meanwhile, rigorous assessment of the uncertainties in LSP retrievals is ongoing, and efforts to reduce these uncertainties represent an active research area. Open source software and hardware are in development, and have greatly facilitated the use of LSP metrics by scientists outside the remote sensing community. This reprint covers the latest developments in sensor technologies, LSP retrieval algorithms and validation strategies, and the use of LSP products in a variety of fields. It aims to summarize the ongoing diverse LSP developments and boost discussions on future research prospects.
