CHAPTER 1
Introduction
The Debate on Climate Change and Water Security
It is still important that the popular myth of water wars somehow be dispelled once and for all. This will not only stop unsettling and incorrect predictions of international conflict over water. It will also discourage a certain public resignation that climate change will bring war, and focus attention instead on what politicians can do to avoid it. ... And it would help to convince water engineers and managers ... that the solutions to water scarcity and security lie outside the water sector in the water/food/trade/economic development nexus.
Wendy Barnaby, "Do Nations Go to War over Water?" (2009, 283)
Much has been written about freshwater conditions around the world with implications for national and international security. The scientific and environmental literature tells us that water will become less available (and its supply more volatile and variable) in the future due to population growth, improved standards of living, increased pollution, and climate change. The economics literature claims that existing institutions and policy interventions are not keeping pace with increased scarcity and that water-supply and water-demand technological advancements are much less affordable to the developing world. Adopting these arguments, the popular press prophesies a less stable world, plagued by water wars that will result from competition over increasingly scarce water.
Despite these gloomy contentions and predictions, there are cases where, in spite of water scarcity (and variability) and the political and economic challenges that follow, cooperation and coordination are evidenced. Interestingly, the large majority of the works that document such cases focus on one particular river basin or a comparative analysis across a small number of basins and thus may be of lesser utility for general conclusions. More recently, scholars have attempted to more generally investigate the concepts of scarcity and variability, utilizing the corpus of international water treaties as well as other forms of large datasets and their corresponding empirical methodologies.
The main research question we attempt to address in this book is whether increased scarcity and/or variability of water resources leads parties (states) that share international water bodies to engage in violent conflict or even war, or whether there are mechanisms that help them mitigate such situations. To answer this question, this book develops an interdisciplinary approach for considering international water management under increased scarcity and variability. Our approach applies a theory rooted in international relations and economics to the analysis of scarcity, variability, and cooperation. It demonstrates the utility of the theory, utilizing the global set of transboundary water bodies. It provides a framework that allows scholars and policymakers to reflect on various future scenarios and assess the impact of policy interventions on the regional and global level.
The book begins with this introduction, which presents the "water wars" argument and considers aspects of cooperation, setting the groundwork for chapter 2 and for the rest of the empirical chapters that support our thesis in the book. Chapter 2 introduces the general scarcity-cooperation contention/theory by considering the relationship between scarcity and variability and the emergence of treaties. Chapter 3 empirically investigates that contention using econometric and statistical methods. Building on this empirical investigation, chapter 4 explores the way treaties (and the mechanisms they codify) assuage conflict and promote cooperation. Chapters 5 and 6 build on the empirical results of chapter 4, which demonstrate that certain institutional mechanisms promote sustained cooperation and coordination. Chapters 5 and 6 focus on case studies that demonstrate the utility of such mechanisms. The book's concluding chapter summarizes the main arguments and results of the book with policy implications, in addition to assessing some of the shortcomings of our argument, and providing suggestions for future research. A detailed description of the book's outline and organization is provided later in the chapter.
CLIMATE AND HYDROLOGY
Climatic conditions have a direct impact on the hydrology of river basins. Climatic change will most likely affect the variability of river flows and have a variety of additional impacts on the hydrologic cycle (Jury and Vaux 2005; Miller and Yates 2006). The change in flow variability will affect populations, who will be less able to plan based on water availability and supply trends (Milly et al. 2008). Changes will not be consistent, and regions will experience either increases or decreases in river discharge compared with present observations (Palmer et al. 2008).
The Fourth and Fifth Assessment Reports of the Intergovernmental Panel on Climate Change (IPCC 2007, 2013) reiterate the trend in global surface temperature for the end of the twenty-first century. Warming will continue to exhibit interannual-to-decadal variability (IPCC 2007, 1–10). The Fifth Assessment Report further suggests that "changes in the global water cycle in response to the warming over the 21st century will not be uniform. The contrast in precipitation between wet and dry regions and between wet and dry seasons will increase, although there may be regional exceptions" (IPCC 2013, 18). The Fourth Assessment Report confirms the findings from the Third Assessment Report, stating that "one major implication of climate change for agreements between competing users (within a region or upstream versus downstream) is that allocating rights in absolute terms may lead to further disputes in years to come when the total absolute amount of water available may be different" (IPCC 2001, § 4.7.3).
While the hydrologic forecasts of the impact of climate change on future runoff of rivers are only as good as the models used for their prediction, all models suggest significant changes (Doll and Schmied 2012; Nohara et al. 2006; Gosling et al. 2011). Results of expected future changes in levels and trends of several hydrologic variables at a global scale for 2081–2100 can be found in the IPCC report (IPCC 2013, 45). Among the six variables listed in the IPCC report, the three relevant to our work demonstrate a distributional range of both increase and decrease in precipitation (-0.8 to +0.8 millimeters per day), evaporation (-1 to +0.8 millimeters per day), and runoff (-40 to +40%), suggesting wide variability across different parts of the world.
The impact of climate change will be felt most acutely through its effects on water resources and through these on the rest of society. Most evidence suggests that climate change will not change the basic nature of threats to water resources, but rather will affect the severity and timing of these threats (Doczi and Calow 2013, 35). As suggested by many recent hydrological studies (e.g. Milly et al. 2005; Milliman et al. 2008), a significant increase in river flow variability has already been observed. Furthermore, it is expected that future climate change will extend that variability beyond the range already observed (IPCC 2007, 31; Milly et al. 2008).
HYDROLOGIC VARIABILITY, INSTITUTIONS AND CONFLICT AND COOPERATION
Hydrologic variability creates a significant challenge especially for countries sharing international river basins. Unanticipated high-flow or low-flow events may lead to flooding, severe drought, destruction of infrastructure and human lives, and water resource disputes. These events may, in turn, give rise to economic shocks and political tensions and in some cases even armed conflict (Drury and Olson 1998; Nel and Righarts 2008; Hendrix and Salehyan 2012). In the context of interstate relations, political tensions and other types of conflict-ridden water-related events may unfold not just in basins devoid of institutional capacity (such as water treaties) but also in basins where water treaties have been negotiated. In other words, climate change could increase the probability of flow below treaty specifications and expectations, leading to noncompliance and consequent hostilities between riparians (Ansink and Ruijs, 2008; Dinar, Dinar, and Kurukulasuriya 2011; Dinar et al. 2015). Interestingly, some scholars have argued that water supply variability (as a function of climate change) may actually be an impetus for cooperation whereby riparian states negotiate water agreements or revise an existing treaty (Brochmann and Hensel 2009; Dinar et al. 2010b).
While the existence of a treaty may be an important factor in assuaging conflict wrought by water scarcity and variability, treaty design may be equally important. De Stefano et al. (2012) distinguish between flexible and non-flexible treaty mechanisms to deal with water variability. They identify four major mechanisms, namely (1) water allocation, (2) water variability management, (3) conflict resolution, and (4) river basin organization. They claim that having one or a subset of these mechanisms enhances treaty resilience in dealing with water variability.
Additional features that may help in dealing with water variability and reduce conflict include issue linkage (Pham Do, Dinar, and McKinney 2012), compensation mechanisms or side payments (Dinar 2008), and water borrowing mechanisms to allow water-stressed riparians emergency access to water in a bad year with the understanding of repayment in the future. For example, the treaty between Mexico and the United States on the Rio Grande (Rio Bravo), which was renegotiated in 2014, reflects a much higher level of cooperation. The treaty allows for reservoir storage capacity in the United States in abundant years, for use by Mexico in dry years, up to Mexico's allocated share. Finally, the concept of strategic alliance also serves to deal with water variability and assuage conflict (A. Dinar 2009). The strategy entails expanding the pie of negotiation possibilities by allowing for out-of-basin water transfers (Carter et al. 2015).
Consequently, when designing water agreements or appending an outdated one, water negotiators need to forecast the distribution of water flow, in order to design an effective treaty. Having high-quality flow data will also determine the appropriate treaty stipulations and institutional mechanisms that can deal with future challenges (Dinar et al. 2015). Real-time data can also provide policymakers and researchers with the ability to predict extreme weather events, and address their economic impact on an existing treaty or shared river basin.
In the next section we further investigate whether increased water scarcity and variability affect the relations between riparian states. We largely review the academic literature (international relations and economics), rather than the popular press, which more commonly prophesies sensationalist wars over water.
THE WATER SCARCITY–WAR DISCOURSE
Many events taking place around the world make headlines as they impact global security. However, environmental change might have the most significant impacts. Along with extreme and frequent weather patterns, rising sea levels, and other natural hazards, global warming has negative effects on freshwater resource availability, potentially leading to serious long-term social and political impacts. Such a situation prompts policymakers, politicians, and researchers to think in terms of security risks. For example, the Office of the Director of National Intelligence (2012) suggests that international water disputes, a result of increased water scarcity, will affect the security interests of not only riparian states but also the United States.
Analysts expect that climate change will intensify security concerns both within (domestic) and between (international) countries that share basins (Gleick 1993; Nordas and Gleditsch 2007). While in this book we do not address domestic issues, it has been argued (Barnett 2003) that climate change, via direct and indirect negative impacts, will undermine institutions and jeopardize the well-being of large populations. Climate change, through its impact on resource availability and water variability, can lead to uncertainty in property rights as well as changes in land productivity, forest cover, and water availability. These differential effects on the resource base are potential triggers for conflict among basin states (Gartzke 2012).
Recent research has found causal linkages between climate change and increased levels of conflict, including civil wars, mainly in developing countries (Barnett and Adger 2007; Klare 2001; Hensel, Mitchell, and Sowers 2006). However, as argued by Gartzke (2012, 179), economic and industrial development, which contribute to climate change, also contribute to international peace because development reduces the inclination of states to fight. In addition, Gartzke asserts that warfare is a much more costly approach to solving conflicts among states, especially compared with bargaining alternatives (180). In a global analysis of transboundary basins, Tir and Stinnett (2012) find that water scarcity could contribute to interstate tensions and increase the risk of military conflict. However, the same study argues that to prevent conflicts from escalating, agreements with strong institutional features have to be in place. A regional study on the Aral Sea Basin (Bernauer and Siegfried 2012) identifies climate change as a likely trigger of political tensions over water allocation among the basin states. Yet, the authors conclude that a climate change–induced militarized dispute over water in the basin is unlikely.
In general, two types of studies have rejected predictions of wars over water. The first type is more theoretical in nature. Such works make qualitative arguments and provide logical consequences and extrapolation, often buttressed by historical and case-specific evidence (e.g. Gleditsch 1998; Wolf 1998). The second type is more empirical and statistical, utilizing econometric tools to provide more generalizable and global results (e.g. Yoffe, Wolf, and Giordano 2003).
This book follows the line of thought that climate change–induced scarcity and water variability leads to conflict, as does any scarce resource that is in demand by different individuals or states. The book expands on our recent work, developing a theory of conflict and cooperation under conditions of scarcity and variability with application to various contexts at the global level.
THE RELEVANCE OF THE BOOK TO THE DEBATE ON WATER CONFLICT AND COOPERATION
This book develops and demonstrates the application and usefulness of an interdisciplinary approach for considering international water management under increased scarcity and variability. The book exhibits the usefulness of the theory, utilizing the global set of transboundary water bodies. By doing so, the book provides a framework that allows scholars and policymakers to reflect on various future scenarios and assess the impact of policy interventions on the regional and global levels with implications for conflict and cooperation. Finally, the book considers strategies and other forms of incentives that help assuage conflict and motivate cooperation despite scarcity and variability. We briefly review here the literature pertaining to the main variables that are related to conflict and cooperation in the context of international water. An expanded literature review will be provided in a separate chapter.
Countries cooperate over water bodies they share for several reasons. The economics and international relations literature suggests that they do so because they face challenges they cannot overcome themselves; because they anticipate externalities in dealing with pollution, flood control, or hydropower; or for reasons of economies of scale, where parties anticipate being better off cooperating when facing certain water scarcity situations (Just and Netanyahu 1998; S. Dinar 2009). Countries also cooperate so as to formalize historical uses of water; to establish fairness and equity considerations in water allocation procedures; and to provide simple recognition of rights to shared water (Wolf 1999; Wolf and Hamner 2000).
The economics and international relations literature that applies statistical tools and analysis to international water datasets (Brochmann and Hensel 2009; Espey and Towfique 2004; Gleditsch et al. 2006; Hensel, Mitchell, and Sowers 2006; Song and Whittington 2004; Tir and Ackerman 2009; Toset, Gleditsch, and Hegre 2000; S. Dinar 2009; Dinar, Dinar, and Kurukulasuriya 2011) has gone a long way already in developing a theory that explains various aspects of cooperation over shared water. We adopt a number of these variables in our study.
