117. Agricultural Groundwater Revolution : Comprehensive Assessment of Water Management in Agriculture

Author

Mark Giordano, Karen G Villholth, Mark Giordano, and Karen G Villholth

Subjects
Water-supply, Agricultural, Groundwater--Management
Abstract

While addressing the issues of using groundwater in agriculture for irrigation in the developing world, this book discusses the problems associated with the degradation and overexploitation of using it. It explores the practiced and potential methods for its management in the context of agricultural development.

Abstract

A complete treatment of the theory and practice of groundwater engineering, The Handbook of Groundwater Engineering, Second Edition provides a current and detailed review of how to model the flow of water and the transport of contaminants both in the unsaturated and saturated zones, covers the production of groundwater and the remediation of contaminated groundwater.

149. Managing Common Pool Groundwater Resources : An International Perspective

Author

Subjects
Groundwater--Management
Abstract

Woldwide, developed and developing countries increasingly depend on groundwater resources for domestic water supply. Since groundwater is a hidden resource and individuals cannot see how much has been used and what is left, this book attempts to make global groundwater use more visible so that policy makers can make informed decisions as to its management. Organized into six geographical regions, the authors describe the various physical, cultural and institutional challenges of groundwater policy and management faced by countries worldwide. Analysis of the challenges and responses to groundwater management at the national level hopes to generate a broader understanding for societies across the globe.Each chapter provides the physical geography and demographics of the country, its water use, problems, law, politics and policy and future implications. Chapters on representative countries within North America, Western and Eastern Europe, the Middle East, Australia and China and Africa provide a comprehensive perspective of groundwater issues internationally.

Abstract

We propose and exemplify a framework to assess Natural Background Levels (NBLs) of target chemical species in large-scale groundwater bodies based on the context of Object Oriented Spatial Statistics. The approach enables one to fully exploit the richness of the information content embedded in the probability density function (PDF) of the variables of interest, as estimated from historical records of chemical observations. As such, the population of the entire distribution functions of NBL concentrations monitored across a network of monitoring boreholes across a given aquifer is considered as the object of the spatial analysis. Our approach starkly differs from previous studies which are mainly focused on the estimation of NBLs on the basis of the median or selected quantiles of chemical concentrations, thus resulting in information loss and limitations related to the need to invoke parametric assumptions to obtain further summary statistics in addition to those considered for the spatial analysis. Our work enables one to (i) assess spatial dependencies among observed PDFs of natural background concentrations, (ii) provide spatially distributed kriging predictions of NBLs, as well as (iii) yield a robust quantification of the ensuing uncertainty and probability of exceeding given threshold concentration values via stochastic simulation. We illustrate the approach by considering the (probabilistic) characterization of spatially variable NBLs of ammonium and arsenic detected at a monitoring network across a large scale confined groundwater body in Northern Italy.
