This book is a compilation of papers examining the impacts of global change (GC) on water resources systems. Mainly focusing on groundwater resources in Western Mediterranean countries, it shows that this topic is one of the most important challenges facing society. The papers explore developments in both Southern Europe and North Africa, where major impacts on the sustainability, quantity, quality, and management of water resources are expected to emerge. Although most global change publications focus on surface water, the number of research papers addressing global change and groundwater has grown rapidly in recent years. Continuing that welcome trend, this book gathers the main findings presented at the “Congress on Groundwater and Global Change in the Western Mediterranean” (Granada, Spain, November 6–9, 2017), which brought together researchers and technicians interested in groundwater issues affecting this geographic area.

This book aims at deriving governance and sustainability lessons from analysing the implementation and management of some major irrigation programs in the Mediterranean Region. Eight countries are targeted, namely: Spain, Italy, Albania, Turkey, Jordan, Egypt, Tunisia and Morocco. The main focus programs include the modernisation and rehabilitation of the existing irrigation systems, the transfer of irrigation management responsibilities to water users’ organizations, public private partnerships arrangements, the monitoring & evaluation of participatory irrigation management and transfer processes, and the governance of groundwater resources for irrigation. The adopted approach relies on learning from the value of each single experience, and on advancing solutions that emerge from their comparative analysis and that may be of guidance to those engaged in these programs. The country experiences indicated that often times, significant shortcomings in the implementation of these programs have occurred and hopefully, this book could be a source of inspiration for the corrective actions needed.

This book is a hard copy of the editorial and all the papers in a Special Issue of the peer-reviewed open access journal ‘Water’ on the theme ‘Managed Aquifer Recharge for Water Resilience’. Managed aquifer recharge (MAR) is the purposeful recharge of water to aquifers for subsequent recovery or environmental benefit. MAR is increasingly used to make water supplies resilient to drought, climate change and deteriorating water quality, and to protect ecosystems from declining groundwater levels. Global MAR has grown exponentially to 10 cu.km/year and will increase ten-fold within a few decades. Well informed hydrogeologists, engineers and water quality scientists are needed to ensure that this investment is effective in meeting increasingly pressing needs. This compilation contains lessons from many examples of existing projects, including several national and continental summaries. It also addresses the elements essential for identifying and advancing projects such as mapping aquifer suitability and opportunities, policy matters, operational issues, and some innovations in MAR methods and monitoring. This collection exemplifies the state of progress in the science and practice of MAR and is intended to be useful, at least to water managers, water utilities, agricultural water users and urban planners, to facilitate water resilience through new MAR projects.

Water Conservation in the Era of Global Climate Change reviews key issues surrounding climate change and water resources. The book brings together experts from a variety of fields and perspectives, providing a comprehensive view on how climate change impacts water resources, how water pollution impacts climate change, and how to assess potential hazards and success stories on managing and addressing current issues in the field. Topics also include assessing policy impacts, innovative water reuse strategies, and information on impacts on fisheries and agriculture including food scarcity. This book is an excellent tool for researchers and professionals in Climate Change, Climate Services and Water Resources, and those trying to combat the impacts and issues related to Global and Planetary Change. - Covers a wide range of theoretical and practical issues related to how climate change impacts water resources and adaptation, with extended influence on agriculture, food and water security, policymaking, etc. - Reviews mathematical tools and simulations models on predicting potential hazards from climate change in such a way they can be useful to readers from a variety of levels of mathematical expertise - Examines the potential impacts on agriculture and drinking water quality - Includes case studies of successful management of water and pollutants that contribute to climate change

Spatial Modeling in GIS and R for Earth and Environmental Sciences offers an integrated approach to spatial modelling using both GIS and R. Given the importance of Geographical Information Systems and geostatistics across a variety of applications in Earth and Environmental Science, a clear link between GIS and open source software is essential for the study of spatial objects or phenomena that occur in the real world and facilitate problem-solving. Organized into clear sections on applications and using case studies, the book helps researchers to more quickly understand GIS data and formulate more complex conclusions. The book is the first reference to provide methods and applications for combining the use of R and GIS in modeling spatial processes. It is an essential tool for students and researchers in earth and environmental science, especially those looking to better utilize GIS and spatial modeling. - Offers a clear, interdisciplinary guide to serve researchers in a variety of fields, including hazards, land surveying, remote sensing, cartography, geophysics, geology, natural resources, environment and geography - Provides an overview, methods and case studies for each application - Expresses concepts and methods at an appropriate level for both students and new users to learn by example

This report is the presentation of the methodology applied in Italy to spatially disaggregate the computation of the level of water stress from the national to the subnational scale (SDG indicator 6.4.2). Compared to the national assessment, which results in a low level of water stress in the country, the spatial disaggregation of the indicator by the hydrological unit highlighted the presence of basins affected by water stress exceeding 60 per cent (district of the Po river basin). The analysis was performed considering the long-term average of the available fresh water resources calculated on different reference periods (1951-2020, 1961-90, 1991-2020), and this put in evidence the impact of climate change on the level of water stress. This report is part of the series SDG 6.4 MONITORING SUSTAINABLE USE OF WATER RESOURCES PAPERS that collects all the achievements on SDG 6.4. The study was implemented by the Italian Institute for Environmental Protection and Research (ISPRA), responsible for the model and data used to assess the total renewable freshwater resources, and the Italian National Institute of Statistics (ISTAT), which has provided the methodology and the official statistics related to water withdrawals by economic sector (Agriculture, Services, and Industry). The study is the outcome of an agreement between FAO and ISPRA under the Integrated Monitoring Initiative for SDG 6 (IMI-SDG6), designed to produce a map of Italy showing the SDG indicator 6.4.2 “Level of water stress: freshwater withdrawal as a proportion of available freshwater resources” disaggregated at river basin district level.
