Book Description
This book highlights recent efforts to sustain agricultural productivity in Tunisia under a stressed environment and aridity conditions. This book's authors gathered a unique set of applications and approaches, including techniques applied to increase yield and preserve the environment, such as organic farming and using biochar amendment and its effects on soils' physicochemical properties. This book also presents water resources management and water management practices for sustainable soil production, diagnosis, and new farming technologies to enhance water-use efficiency. The book also addresses current livestock strategies intended to maintain production sustainability, increase fish productivity, and initiatives for sustainable tourism development. Given its scope, the book offers a valuable guide for policy planners, decision-makers, stakeholders, researchers, and graduate students in Tunisia and neighboring countries with similarly stressed environmental conditions.

Book Description
The interaction of the lithosphere and hydrosphere sets the boundary conditions for life, as water and the nutrients extracted from rocks are essential to all known life-forms. Water-rock interaction also affects the fate and transport of pollutants, mediates the long-term cycling of fluids and metals in the earth's crust, impacts the migration and

Book Description
The Cretaceous Chalk aquifers of Northern Europe underlie and support many sensitive ecosystems whilst at the same time being an important source of drinking water. Understanding, managing and protecting this valuable asset has always been a challenge and this volume brings together 25 papers representing current knowledge of the Chalk across a variety of thematic sections. The contributions look at aquifer properties, geology and karst; groundwater monitoring in the Chalk; groundwater management; groundwater-fed wetlands; engineering in the Chalk; heat and solute transport; diffuse pollution; and point source pollution. Geographically, the book includes studies undertaken in England, France, Belgium and Denmark. As well as academic papers, many of the chapters are practitioner focused and the editors hope that anyone working in Chalk groundwaters in Northern Europe, whether in academic, consultancy, water company or regulatory roles, will find this book an invaluable resource.

Book Description
Des méthodologies innovantes semblent être nécessaires pour mieux détecter l'origine des polluants, et pour la compréhension des processus physiques impliqués dans leur évolution dans le milieu. En outre, il est indispensable de vérifier si le traitement conduit à une minéralisation complète (efficacité du nettoyage). La mesure isotopique est un outil fondamental pouvant être utilisé dans la gestion d'une pollution : confinement, propagation et possibilités de bioremédiation est proposée dans le projet ISOTO-POL. En illustration de ce principe, le MTBE, fréquemment détecté dans les zones aquifères, est donné comme exemple. Les isotopes stables ont été utilisés avec succès pour démontrer la biodégradation naturelle ou améliorée des hydrocarbures pétroliers et additifs dans le sol et les eaux souterraines. Jusqu'à présent, seul le fractionnement isotopique total en 13C a été exploité, en utilisant la teneur en isotope mesurée par spectrométrie de masse de rapport isotopique (irm-MS). Mais cela conduit à une perte d'information importante concernant le site de la molécule concerné par la transformation. En revanche, la spectrométrie RMN offre la capacité de mesurer, site par site les rapports 13C/12C, donnant accès à de nouvelles informations. La méthodologie RMN isotopique permettra de déterminer les effets isotopiques position-spécifiques impliqués dans les transformations physiques (volatilisation et migration), chimiques (hydrolyse et oxydation) ainsi que la dégradation par les microorganismes. La construction d’un modèle fournira un moyen unique permettant la détection et le traçage détaillé d'un polluant donné, mais également la détermination de son origine

Book Description
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.

Book Description
A lake, as a body of water, is in continuous interaction with the rocks and soils in its drainage basin, the atmosphere, and surface and groundwaters. Human industrial and agricultural activities introduce new inputs and processes into lake systems. This volume is a selection of ten contributions dealing with diverse aspects of lake systems, including such subjects as the geological controls of lake basins and their histories, mixing and circulation patterns in lakes, gaseous exchange between the water and atmosphere, and human input to lakes through atmospheric precipitation and surficial runoff. This work was written with a dual goal in mind: to serve as a textbook and to provide professionals with in-depth expositions and discussions of the more important aspects of lake systems.

Book Description
This publication is a compilation of the results obtained under a co-ordinated research project undertaken from 2000 to 2003 including hydrologists, hydrogeologists and meteorologists from 14 Mediterranean countries, who collaborated at national and regional levels. The isotopic composition of precipitation is closely connected with the conditions for rain formation, and stable isotopes are useful tools for investigating the precipitation and formation conditions, and for monitoring their changes in parallel to the observed climatic changes.

Book Description
This book has been published by Allenvi (French National Alliance for Environmental Research) to coincide with the 22nd Conference of Parties to the United Nations Framework Convention on Climate Change (COP22) in Marrakesh. It is the outcome of work by academic researchers on both sides of the Mediterranean and provides a remarkable scientific review of the mechanisms of climate change and its impacts on the environment, the economy, health and Mediterranean societies. It will also be valuable in developing responses that draw on “scientific evidence” to address the issues of adaptation, resource conservation, solutions and risk prevention. Reflecting the full complexity of the Mediterranean environment, the book is a major scientific contribution to the climate issue, where various scientific considerations converge to break down the boundaries between disciplines.
