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.

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses groundwater governance, a subject internationally recognized as crucial and topical for enhancing and safeguarding the benefits of groundwater and groundwater-dependent ecosystems to humanity, while ensuring water and food security under global change. The multiple and complex dimensions of groundwater governance are captured in 28 chapters, written by a team of leading experts from different parts of the world and with a variety of relevant professional backgrounds. The book aims to describe the state-of-the-art and latest developments regarding each of the themes addressed, paying attention to the wide variation of conditions observed around the globe. The book consists of four parts. The first part sets the stage by defining groundwater governance, exploring its emergence and evolution, framing it through a socio-ecological lens and describing groundwater policy and planning approaches. The second part discusses selected key aspects of groundwater governance. The third part zooms in on the increasingly important linkages between groundwater and other resources or sectors, and between local groundwater systems and phenomena or actions at the international or even global level. The fourth part, finally, presents a number of interesting case studies that illustrate contemporary practice in groundwater governance. In one volume, this highly accessible text not only familiarizes water professionals, decision-makers and local stakeholders with groundwater governance, but also provides them with ideas and inspiration for improving groundwater governance in their own environment.

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 Groundwater and Ecosystems written by Luis Ribeiro and published by CRC Press. This book was released on 2013-06-13 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater resources are facing increasing pressure from consuming and contaminating activities. There is a growing awareness that the quantitative and qualitative preservation of groundwater resources is a global need, not only to safeguard their future use for public supply and irrigation, but also to protect those ecosystems that depend partially or entirely on groundwater to maintain their species composition and natural ecological processes. Known as groundwater dependent ecosystems (GDEs), they have been a fast-growing field of research during the last two decades. This book is intended to provide a diverse overview of important studies on groundwater and ecosystems, including a toolbox for assessing the ecological water requirements for GDEs, and relevant case studies on groundwater/surface-water interactions, as well as the role of nutrients in groundwater for GDEs and ecosystem dependence (vegetation and cave fauna) on groundwater. Case studies are from Australia (nine studies) and Europe (12 studies from nine countries) as well as Argentina, Canada and South Africa. This book is of interest to everybody dealing with groundwater and its relationship with ecosystems. It is highly relevant for researchers, managers and decision-makers in the field of water and environment. It provides up-to-date information on crucial factors and parameters that need to be considered when studying groundwater-ecosystem relationships in different environments worldwide.

This book was released on 2022-03-02 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accounting for approximately 99% of all liquid freshwater on Earth, groundwater has the potential to provide societies with tremendous social, economic and environmental benefits and opportunities. However, this natural resource is often poorly understood, and consequently undervalued, mismanaged and even abused. In spite of its overall abundance, groundwater remains vulnerable to over-exploitation and pollution, both of which can have devastating effects on the resource and its availability. In the context of growing water scarcity across many parts of the world, the enormous potential of groundwater and the need to manage it sustainably can no longer be overlooked. The 2022 edition of The United Nations World Water Development Report describes the challenges and opportunities associated with the development, management and governance of groundwater across the world.

Available in PDF, EPUB and Kindle. Book excerpt: As the world population grows, so does the demand for food, putting unprecedented pressure on agricultural lands. In many desert dryland regions, however, intensive cultivation is causing their productivity to decline precipitously. "Rewilding" the least productive of these landscapes offers a sensible way to reverse the damage, recover natural diversity, and ensure long-term sustainability of remaining farms and the communities they support. This accessibly written, groundbreaking contributed volume is the first to examine in detail what it would take to retire eligible farmland and restore functioning natural ecosystems. The lessons in Rewilding Agricultural Landscapes will be useful to conservation leaders, policymakers, groundwater agencies, and water managers looking for inspiration and practical advice for solving the complicated issues of agricultural sustainability and water management.

Download or read book Groundwater Depletion in the United States 1900 2008 written by Leonard F Konikow and published by CreateSpace. This book was released on 2014-08-01 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: A natural consequence of groundwater withdrawals is the removal of water from subsurface storage, but the overall rates and magnitude of groundwater depletion in the United States are not well characterized. This study evaluates long- term cumulative depletion volumes in 40 separate aquifers or areas and one land use category in the United States, bringing together information from the literature and from new analy- ses. Depletion is directly calculated using calibrated ground- water models, analytical approaches, or volumetric budget analyses for multiple aquifer systems. Estimated groundwater depletion in the United States during 1900-2008 totals approx- imately 1,000 cubic kilometers (km3). Furthermore, the rate of groundwater depletion has increased markedly since about 1950, with maximum rates occurring during the most recent period (2000-2008) when the depletion rate averaged almost 25 km3 per year (compared to 9.2 km3 per year averaged over the 1900-2008 timeframe).
