Irrigation Systems and Practices in Challenging Environments
The book Irrigation Systems and Practices in Challenging Environments is divided into two interesting sections, with the first section titled Agricultural Water Productivity in Stressed Environments, which consists of nine chapters technically crafted by experts in their own right in their fields of expertise. Topics range from effects of irrigation on the physiology of plants, deficit irrigation practices and the genetic manipulation, to creating drought tolerant variety and a host of interesting topics to cater for the those interested in the plant water soil atmosphere relationships and agronomic practices relevant in many challenging environments, more so with the onslaught of global warming, climate change and the accompanying agro-meteorological impacts. The second section, with eight chapters, deals with systems of irrigation practices around the world, covering different climate zones apart from showing casing practices for sustainable irrigation practices and more efficient ways of conveying irrigation waters - the life blood of agriculture, undoubtedly the most important sector in the world.
Recent Advances in Environmental Science from the Euro-Mediterranean and Surrounding Regions
This volume includes the papers presented during the 1st Euro-Mediterranean Conference for Environmental Integration (EMCEI) which was held in Sousse, Tunisia in November 2017. This conference was jointly organized by the editorial office of the Euro-Mediterranean Journal for Environmental Integration in Sfax, Tunisia and Springer (MENA Publishing Program) in Germany. It aimed to give a more concrete expression to the Euro-Mediterranean integration process by supplementing existing North-South programs and agreements with a new multilateral scientific forum that emphasizes in particular the vulnerability and proactive remediation of the Euro-Mediterranean region from an environmental point o...
Agriculture Productivity in Tunisia Under Stressed Environment
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.

Etude de L'Irrigation Localisée Souterraine Sur la Culture D'Aubergine
Dans les régions arides et semi-arides les ressources en eau sont rares et le plus souvent de qualité médiocre. L'introduction du système d'irrigation goutte à goutte constitue un moyen d'économie d'eau et de valorisation des eaux saumâtres. Pour développer davantage l'économie en eau d'irrigation, nous avons réalisé un essai expérimental à l'ISA Chott Meriem- Tunisie, en faisant une comparaison entre le système d'irrigation goutte à goutte enterré et en surface sur une culture d'aubergine. Nous avons déterminé les caractéristiques physiques du sol par des analyses au laboratoire et des mesures sur le terrain, le suivi de la dynamique de l'eau dans le sol, l'évolution du ...
Résolution Des Équations de la Dynamique de L'Eau Dans Le Sol
Le processus physique de l'eau pénétrant dans le sol à partir de sa surface est généralement connu sous le nom d'infiltration. L'infiltration est une composante primordiale dans le cycle hydrologique. Il y a un lien étroit entre la quantité d'eau infiltrée dans le sol et son processus de redistribution dans les zones non saturées. Cette redistribution d'eau dépend des conditions d'humidité, de la pression d'eau et de la perméabilité en zone non saturée. L'écoulement de l'eau dans le sol est caractérisé par des paramètres qui prennent en compte les paramètres hydrodynamiques du sol, les conditions initiales et les conditions aux limites du sol considéré. Les simulations numériques scientifiques reposent sur la mise en oeuvre de modèles théoriques utilisant souvent la technique dite des éléments finis. La simulation permet la détermination des paramètres hydrodynamiques et des paramètres de transport, la diminution du pas de temps, l'introduction des valeurs de flux horaires et la possibilité de lancer le modèle sur des périodes plus longues et provoquer des scénarios.
Pompage éolien des eaux souterraines
Le present travail porte sur l'etude d'une installation eolienne de pompage des eaux souterraines destinee a l'irrigation des cultures. Une etude statistique permettant la determination du potentiel eolien de la Tunisie, a ete presentee. Cette etude nous a conduit a choisir la region de Chott Mariem du sahel tunisien, comme region favorable pour l'application du systeme de pompage eolien des eaux souterraines grace a son potentiel eolien important. L'application traitee se rapporte au pompage eolien avec les deux modes, a savoir le pompage eolien par une eolienne mecanique et le pompage eolien electrique par un aerogenerateur. Une premiere partie de ce travail traite le dimensionnement de deux installations de pompage eolien, en se basant sur les donnees caracteristiques de la region (le vent disponible et la source d'eau) et des besoins en eau d'irrigation des cultures. La seconde partie s'interesse au couplage de l'ensemble des composants, de chaque installation pour etre modelise sous l'environnement TRNSYS. Les resultats de la simulation de deux systemes de pompage eolien presentent les debits mensuels qui pourraient etre obtenus par ces systemes.
Wired/Wireless Internet Communications
This book constitutes the thoroughly refereed post-conference proceedings of the 12th International Conference on Wired/Wireless Internet Communication, WWIC 2014, held in Paris, France, during May 27-28, 2014. The 22 revised full papers presented were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on wireless and wired networks; resource management and next generation services; next generation services, network architecture and applications.
New Prospects in Environmental Geosciences and Hydrogeosciences
This edited book gives a general overview on current research, focusing on geoenvironmental issues and challenges in hydrogeosciences in model regions in Asia, Europe, and America, with a focus on the Middle East and Mediterranean region and surrounding areas. This proceedings book is based on the accepted papers for oral/poster presentations at the 2nd Springer Conference of the Arabian Journal of Geosciences (CAJG-2), Tunisia 2019. It offers a broad range of recent studies that discuss the latest advances in geoenvironmental and hydrogeosciences from diverse backgrounds including climate change, geoecology, biogeochemistry, water resources management, and environmental monitoring and asses...
