Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to document for the first time the dimensions and requirements of effective integrated groundwater management (IGM). Groundwater management is a formidable challenge, one that remains one of humanity’s foremost priorities. It has become a largely non-renewable resource that is overexploited in many parts of the world. In the 21st century, the issue moves from how to simply obtain the water we need to how we manage it sustainably for future generations, future economies, and future ecosystems. The focus then becomes one of understanding the drivers and current state of the groundwater resource, and restoring equilibrium to at-risk aquifers. Many interrelated dimensions, however, come to bear when trying to manage groundwater effectively. An integrated approach to groundwater necessarily involves many factors beyond the aquifer itself, such as surface water, water use, water quality, and ecohydrology. Moreover, the science by itself can only define the fundamental bounds of what is possible; effective IGM must also engage the wider community of stakeholders to develop and support policy and other socioeconomic tools needed to realize effective IGM. In order to demonstrate IGM, this book covers theory and principles, embracing: 1) an overview of the dimensions and requirements of groundwater management from an international perspective; 2) the scale of groundwater issues internationally and its links with other sectors, principally energy and climate change; 3) groundwater governance with regard to principles, instruments and institutions available for IGM; 4) biophysical constraints and the capacity and role of hydroecological and hydrogeological science including water quality concerns; and 5) necessary tools including models, data infrastructures, decision support systems and the management of uncertainty. Examples of effective, and failed, IGM are given. Throughout, the importance of the socioeconomic context that connects all effective IGM is emphasized. Taken as a whole, this work relates the many facets of effective IGM, from the catchment to global perspective.

Download or read book Statistical Methods in Water Resources written by D.R. Helsel and published by Elsevier. This book was released on 1993-03-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data on water quality and other environmental issues are being collected at an ever-increasing rate. In the past, however, the techniques used by scientists to interpret this data have not progressed as quickly. This is a book of modern statistical methods for analysis of practical problems in water quality and water resources.The last fifteen years have seen major advances in the fields of exploratory data analysis (EDA) and robust statistical methods. The 'real-life' characteristics of environmental data tend to drive analysis towards the use of these methods. These advances are presented in a practical and relevant format. Alternate methods are compared, highlighting the strengths and weaknesses of each as applied to environmental data. Techniques for trend analysis and dealing with water below the detection limit are topics covered, which are of great interest to consultants in water-quality and hydrology, scientists in state, provincial and federal water resources, and geological survey agencies.The practising water resources scientist will find the worked examples using actual field data from case studies of environmental problems, of real value. Exercises at the end of each chapter enable the mechanics of the methodological process to be fully understood, with data sets included on diskette for easy use. The result is a book that is both up-to-date and immediately relevant to ongoing work in the environmental and water sciences.

Download or read book An Evaluation of Policy Instruments for Sustainable Groundwater Management written by Ellen Marie Bruno and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Many groundwater basins worldwide have seen significant reductions in the water table over time, and this is increasingly problematic in the face of climate change. Climate change is expected to cause more variability in precipitation and thus more variable surface water supplies. Groundwater acts as a buffer to fluctuations in surface water supplies, and is a critical resource in reducing the costs of climate change to agriculture. Concerns over groundwater management are particularly strong in California. The state passed the Sustainable Groundwater Management Act in 2014 to provide a statewide framework for local agencies to manage groundwater. The act identifies overdrafted basins in the state and requires local groundwater agencies to correct groundwater overdraft conditions. Importantly, the groundwater law gives these local water agencies new authority to measure extraction, charge fees for pumping, and facilitate the trading of property rights for pumping. To inform water policy, I conduct an evaluation of the economic impacts of three policy instruments to manage groundwater resources: cap and trade, excise taxes, and command and control. In general, market-based instruments are more likely to obviate efficiency losses relative to command-and-control policies. Of these, cap and trade may be particularly appealing to water agencies that must eliminate overdraft because markets remove the uncertainty in reaching a management goal. However, market power in permit trading is a concern in this setting, and, if present, will reduce the efficiency gains from markets and potentially cause large distributional effects. In my evaluation of groundwater cap-and-trade, I account for the likely presence of market power in groundwater trading. Knowledge of how market power impacts the gains from trade is important for understanding the performance of markets relative to taxes in this setting. Since many water agencies restrict the export of groundwater outside basin boundaries, future groundwater markets will likely be spatially isolated. The exercise of market power may be a defining component of these markets due to the presence of large grower-shippers, the formation of coalitions among buyers and sellers, and/or competition among a few water agencies on a shared basin. To analyze the potential gains from trade in a groundwater permit market and evaluate the impacts of market power on both the magnitude and distribution of benefits, I develop a theoretical model of agricultural groundwater use and trading. The gains from trade in equilibrium are a function of five features of the model: the heterogeneity in demand for groundwater across users, the price elasticity of groundwater demand, the total allowable extraction on the basin, the allocation of permits among users, and the degree of market power. Using a flexible model framework that can reflect any degree of buyer or seller market power in the permit market, I identify the relationship between market power and the efficiency of water trading. I show that the overall efficiency impact of market power (by either buyers or sellers) is small, with a deadweight loss of at most 11% of the surplus under perfect competition. The distributional impacts, however, can be large. I evaluate the distributional impacts of market power by simulating how seller surplus and buyer surplus change as market structure varies. The flexible model of one-sided market power allows us to see how surplus measures change with any degree of market power. I show that the gains from trade accrue rapidly to those with market power. To evaluate the price sensitivity of groundwater users, I empirically estimate the price elasticity of groundwater demand with monthly, well-level groundwater extraction and groundwater price data. The data come from a basin in southern California that underlies the Coachella Valley, a major production region for citrus, dates, grapes, and vegetable row crops. Attaining reliable estimates of the groundwater demand elasticity has been challenging because micro-level data on groundwater extraction is uncommon and groundwater itself is typically free of charge. The Coachella Valley Water District is unique because it deploys a location-based volumetric pricing scheme for groundwater. Exploiting temporal and cross-sectional variation in groundwater extraction prices, I estimate a price elasticity that is the first of its kind to not rely on estimates of pumping cost for price. I report results from an OLS regression of the log of groundwater extraction on the log of prices, controlling for well and month fixed effects and conditioning on a rich array of observables, including weather, surface water use, and artificial groundwater recharge. With a statistically significant price elasticity point estimate of -0.17 that is robust to alternative specifications of the model, results suggest that increases in price modestly reduce extraction. This suggests that a tax on agricultural groundwater pumping will have small effects on basin-wide groundwater extraction, while significantly raising farming costs. Combining this estimate of the groundwater demand elasticity with estimates of the other model parameters, I estimate the gains from groundwater trade for the Coachella Valley. Results show that the gains from introducing water markets are large; economic surplus with trade is about 50% greater than under a command-and-control regime. Given an initial allocation of permits based on land holdings, the cost of compliance from a 20% reduction in basin-wide groundwater extraction can be reduced by 59% with trade. Furthermore, simulations show that the gains from trade remain large over a reasonable range of parameter values, meaning results are likely to generalize to other basins where trading might occur. The gains from trade remain large as the demand elasticity, the cap, the initial permit allocation, and the degree of heterogeneity in demand among users vary. Despite the potential efficiency losses due to market power, total economic surplus under cap-and-trade is still significantly larger than under command and control.In evaluating different policy instruments to manage groundwater for agriculture, my research contributes to the discussion of how best to manage this resource in groundwater-dependent regions around the world. In particular, I shed light on the role of markets to manage water in the presence of imperfect competition. Since the gains from groundwater trade are large even in the presence of market power, the potential of market power should not be used as an argument against the formation of markets.

Download or read book Climate Change and Groundwater written by Walter Dragoni and published by Geological Society of London. This book was released on 2008 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a general consensus that for the next few decades at least, the Earth will continue its warming. This will inevitably bring about serious environmental problems. For human society, the most severe will be those related to alterations of the hydrological cycle, which is already heavily influenced by human activities. Climate change will directly affect groundwater recharge, groundwater quality and the freshwater-seawater interface. The variations of groundwater storage inevitably entail a variety of geomorphological and engineering effects. In the areas where water resources are likely to diminish, groundwater will be one of the main solutions to prevent drought. In spite of its paramount importance, the issue of 'Climate Change and Groundwater' has been neglected. This volume presents some of the current understanding of the topic.
Download or read book Handbook of Catchment Management written by Robert C. Ferrier and published by John Wiley & Sons. This book was released on 2021-07-13 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: HANDBOOK OF CATCHMENT MANAGEMENT In 2010, the first edition of the Handbook of Catchment Management provided a benchmark on how our understanding and actions in water management within a catchment context had evolved in recent decades. Over ten years on, the catchment management concept is entering a new phase of development aligned to contemporary and future challenges. These include climate change uncertainty, further understanding in ecological functioning under change, the drive for a low-carbon, energy efficient and circular society, multiple uses of water, the emergence of new pollutants of concern, new approaches to valuation, finance and pricing mechanisms, stewardship and community engagement, the integration of water across the Sustainable Development Goals (SDG) and the link between water, energy and food. These developments are framed within an increasingly data rich world where new analytics, sensor technology and processing power are informing increasingly real-time decision making. The challenge is also to increase cross-compliance and policy integration to meet multiple stakeholder objectives, and to link actions to achieve cost-effective outcomes. In addition, there are a number of new and exciting city, region and basin-scale real-world examples of contemporary and new catchment thinking; integrating science, technology, knowledge and governance to address multiple drivers and complex problems from across the globe. The time is now right, to capture the new challenges facing catchment management and water resources management globally. This revised and updated edition of the Handbook of Catchment Management features: Thoroughly rewritten chapters which provide an up-to-date view of catchment management issues and contexts New case study material highlighting multi-sectoral management in different globally significant basins and different geographical locations Up-to-date topics selected for their resonance not only in natural sciences and engineering, but also in other fields, such as socio-economics, law and policy The Handbook is designed for a broad audience, but will be particularly useful for advanced students, researchers, academics and water sector professionals such as planners, consultants and regulators.
