Abstract

We are pleased to present these 12 papers, all of which were subject to peer review by at least two reviewers. They show the range of economic and policy considerations relevant to the development and implementation of MAR programs. Several papers show novel techniques that can be used to select MAR locations. The importance and economic viability of MAR to semi-arid to arid environments is evident from the use of MAR in both developed and developing regions. Papers demonstrate how MAR can be utilized to meet municipal and agricultural water demands in water-scarce regions, as well as assist in the reuse of wastewater. Some studies explain how stakeholder engagement, ranging from consideration of alternatives to monitoring, and multi-disciplinary analyses to support decision-making are of high value to development and implementation of MAR programs. There is growing recognition of the importance of groundwater and aquifer health to meeting future water needs, as well as the crucial role for strong institutional and governance frameworks for water resources management. The approaches discussed in this collection of papers, along with the complementary and necessary hydrologic and geologic analyses, provide important inputs to water resource managers. We thank the authors for contributing to increased understanding of MAR as a component of sound water management. Sharon B. Megdal and Peter Dillon Guest Editors

Abstract

Drylands are fragile environments and, therefore, highly susceptible to environmental changes. They cover nearly 50% of the world’s land surface and are increasingly being reclaimed by a growing population for food production and urbanization. This makes water resources management in drylands an extremely important issue. The unplanned water resources development may result in aquifer depletion, soil and/or water salinization, loss of water through evapotranspiration due to inadequate irrigation systems, and land degradation (e.g., soil erosion, soil crusting, and sand encroachment).

Abstract

This book on the sustainable use of soils and water addressed a variety of issues related to the utopian desire for environmental sustainability and the deviations from this scene observed in the real world. Competing interests for land are frequently a factor in land degradation, especially where the adopted land uses do not conform with the land capability (the natural use of soil). The concerns of researchers about these matters are presented in the articles comprising this Special Issue book. Various approaches were used to assess the (im)balance between economic profit and environmental conservation in various regions, in addition to potential routes to bring landscapes back to a sustainable status being disclosed.

Abstract

This book focus principally on ions-releasing and other smart dental materials for application in preventive and restorative dentistry, as well as in endodontics in the form of adhesives, resin-based composites, pastes, varnishes, liners and dental cements. Special attention has been given to bioactive materials developed to induce cells differentiation/stimulation, hard tissue formation and exert antimicrobial actions. New innovations are necessary to continue to help reinforcing existing technologies and to introduce new paradigms for treating dental disease and restoring teeth seriously compromised by caries lesions via biomimetic and more biological operative approaches. Dental bioactive materials is arguably the latest research area in dentistry and thus the amount of new research is overwhelming. However, in this day and age of evidence based practice it important for this new information to be distilled into a practical and understandable format.
