recognizes that water disputes result from opposing interests of water users, public or private. A wide range of water conflicts appear throughout history, though rarely are traditional wars waged over water alone. Instead, water has historically been a source of tension and a factor in conflicts that start for other reasons. Water conflicts arise for several reasons, including territorial disputes, a fight for resources, and strategic advantage. Water conflicts can occur on the intrastate and interstate levels. Interstate conflicts occur between two or more neighboring countries that share a transboundary water source, such as a river, sea, or groundwater basin. For example, the

The broad spectrum of water disputes makes them difficult to address, but a wide range of strategies to reduce the risks of such disputes are available. Local and international laws and agreements can help improve sharing of international rivers and aquifers. Improved technology and institutions can both improve water availability and water sharing in water-scarce regions.


Causes

can exceed supply, or because control over access and allocation of water may be disputed, or because water management institutions are weak or missing. Elements of a water crisis may put pressures on affected parties to obtain more of a shared water resource, causing diplomatic tension or outright conflict. Tensions and conflicts over water now occur more frequently at the subnational, rather than the transnational, level. Violence between pastoralists and farmers in sub-Saharan Africa are on the rise. Attacks on civilian water systems during wars that start for other reasons have increased, such as in Yemen, Syria, and Iraq. Water scarcity can also exacerbate conflicts and

. These particular rivers became the focus because they had experienced water-related disputes. Specific events cited as evidence include Israel's bombing of Syria's attempts to divert the Jordan's headwaters, and military threats by Egypt against any country building dams in the upstream waters of the Nile. Another factor raising the risks of water conflicts is growing competition for water in water-scarce regions, where necessities for water supply for human use, food production, ecosystems and other uses are running up against water availability. Extreme hydrologic events such as floods and droughts are also worsening the risks of water conflicts. As populations and economic development increase, water demands can also increase, worsening disagreements over the allocation and control of limited water in some regions or countries, especially during drought, or in shared international watersheds. Water resources that span international boundaries are more likely to be a source of collaboration and cooperation than war. Scientists working at the

Categories

Water-related conflicts can be categorized as follows: *Trigger: Water as a trigger or root cause of conflict, where there is a dispute over the control of water or water systems or where economic or physical access to water, or scarcity of water, triggers violence. *Weapon: Water as a weapon of conflict, where water resources, or water systems themselves, are used as a tool or weapon in a violent conflict. *Casualty: Water resources or water systems as a casualty of conflict, where water resources, or water systems, are intentional or incidental casualties or targets of violence.

There is no single framework for dealing with pollution disputes local to a nation.


Responses


Cooperation

Transboundary institutions can be designed to promote cooperation, overcome initial disputes and find ways of coping with the uncertainty created by climate change. The effectiveness of such institutions can also be monitored. The Indus River Commission and the 1960 Indus Water Treaty have survived two wars between India and Pakistan despite the two countries' mutual hostility, proving a successful mechanism in resolving conflicts by providing a framework for consultation, inspection and exchange of data.

s. Academic work focusing on water disputes has yet to yield a consistent method for mediating international disputes, let alone local ones. But UNESCO faces optimistic prospects for the future as water conflicts become more public, and as increasing severity sobers obstinate interests.


Arbitration by international organizations

International organizations play the largest role in mediating water disputes and improving water management. From scientific efforts to quantify water pollution, to the World Trade Organization's efforts to resolve trade disputes between nations, many types of water disputes can be addressed through current frameworks and institutions. The
World Trade Organization The World Trade Organization (WTO) is an intergovernmental organization that regulates and facilitates international trade. With effective cooperation in the United Nations System, governments use the organization to establish, revise, and ...
(WTO) can arbitrate water disputes presented by its member states when the disputes are commercial in nature. The WTO has certain groups, such as its Fisheries Center, that work to monitor and rule on relevant cases, although it is by no means the authority on conflict over water resources. Still, water conflict occurring domestically, as well as conflict that may not be entirely commercial in nature may not be suitable for arbitration by the WTO. Because water is so central to agricultural trade, water disputes may be subtly implicated in WTO cases in the form of virtual water, water used in the production of goods and services but not directly traded between countries. Countries with greater access to water supplies may fare better from an economic standpoint than those facing crisis, which creates the potential for conflict. Outraged by agriculture subsidies that displace domestic produce, countries facing water shortages bring their case to the WTO. The WTO plays more of a role in agriculturally based disputes that are relevant to conflict over specific sources of water. Still, it provides an important framework that shapes the way water will play into future economic disputes. One school of thought entertains the notion of war over water, the ultimate progression of an unresolved water dispute—scarce water resources combined with the pressure of exponentially increasing population may outstrip the ability of the WTO to maintain civility in trade issues.


Transboundary water conflicts

Transboundary waters are waters in which two or more different states border the same body of water. In order to reduce the risk of water conflicts, transboundary water arrangements or agreements are often negotiated, but many shared international rivers still lack such treaties. According to the UN, these cooperations are supposed to be equitable and sustainable in that each state does not abuse the water, but rather use the water to their best benefits while protecting and reserving it. International competition over water can arise when one country starts drawing more water from a shared water source. This is often the most efficient route to getting needed water, but in the long term can cause conflict if water is overdrafted. More than 50 countries on five continents are said to be at risk of conflict over water. Moreover, international water law can sometimes exacerbate the potential for conflict: the legal principles of "prior appropriation" and "riparianism" are both implicated in transboundary water conflicts as both can mean that good luck historically and geographically can legally divide countries into those with water abundance and those with scarcity. The current interstate conflicts occur mainly in the Middle East (disputes stemming from the

The Third River is a 172 kilometres long project that started in 1992. It involved an additional channel in capturing the downflow water from the Tigris River and moving it across the marshes and the Euphrates River near Al-Qurna. The project forced half a million marshland people to migrate, burnt down the surrounding towns, and polluted the surrounding farmland and water, making the land inhabitable for thousands of species and human life.

has found that water conflicts among nations are less likely than is cooperation, with hundreds of treaties and agreements in place. Water conflicts tend to arise as an outcome of other social issues. Conversely, the Pacific Institute has shown that while interstate (i.e., nation to nation) water conflicts are increasingly less likely, there appears to be a growing risk of sub-national conflicts among water users, regions, ethnic groups, and competing economic interests. Data from the Water Conflict Chronology show these intrastate conflicts to be a larger and growing component of all water disputes, and that the traditional international mechanisms for addressing them, such as bilateral or multilateral treaties, are not as effective. Some analysts estimate that due to an increase in human consumption of water resources, water conflicts will become increasingly common in the near future. Naho Mirumachi and John Anthony Allan proposed the Transboundary Water Interaction Nexus (TWIN) approach in 2007 as a two-dimensional method to approaching water conflict and cooperation. This model neglects the conventional linear continuum of conflict and cooperation and instead sees the two as coexisting and not mutually exclusive. They postulate that not all cooperation is good, and not all conflict is bad.Zeitoun, Mark and Naho Mirumachi. "Transboundary Water Interaction I: Reconsidering Conflict and Cooperation." In International Environmental Agreements, 8/4, 2008, pp. 297–316 The TWINS approach can also serve as a useful final step after separate. analyses on cooperative methods and conflict intensity measures.Rein, Marlen. "Power Asymmetry in the Mekong River Basin: The Impact of Hydro-Hegemony on Sharing Transboundary Water." In Vienna Journal of East Asian Studies, Volume 8, eds. Rudiger Frank, Ina Hein, Lukas Pokorny, and Agnes Schick-Chen. Vienna: Praesens Verlag, 2016, pp. 127–162. https://doi.org/10.2478/vjeas-2016-0005 The model is split into two parts—the horizontal scale (measures cooperation intensity) and the vertical scale (measures conflict intensity).
