The concept of trans-jurisdictionality introduces complex, multi-dimensional, multi-scalar problems which require complex solutions (Norman et al., 2015). Thus, achieving effective, efficient and legitimate trans-jurisdictional water governance remains a significant challenge at and between the international, regional, national and local level. This section provides an overview of these challenges.
Challenges at the international level
Internationally, state sovereignty remains a fundamental governance challenge for numerous water resources, including approximately 250 trans-boundary river basins, 200 trans-boundary aquifers, various trans-boundary lakes and the oceans, often hindering the development of cooperative forms of governance which engage with, and accommodate the impacts of, decisions in one state on another (Gupta, 2013). This remains the position despite the continual refinement of water rules and practice (see, e.g. the Helsinki Rules, 1966; Berlin Rules, 2004; Convention on the Law of Non-Navigational Uses of International Watercourses; ILC Articles on Transboudary Aquifers, 2008; and other related regional conventions/agreements such as the UNECE Convention on the Protection and Use of Trans-boundary Watercourses and International Lakes) which has sought to ensure the equitable use of international watercourses and their waters to deliver better protection, preservation and management.
Scholars have explored a number of concepts aimed at addressing these challenges including, for example, cooperative sovereignty (Moynihan, 2014), Integrated Water Resources Management (IWRM) (Zeitoun, 2013), and regional cooperation models and agreements (see Eckstein, 2002; Salman, 2007; McIntyre, 2007, 2010; Biswas, 2004; Lim, 2014; Moynihan, 2014) in order to identify the elements necessary to achieve successful trans-jurisdictional water governance. The elements identified have included the need for âshared visionsâ among relevant organizations and communities, the importance of âcommunities of interestsâ, notions of âshared sovereigntyâ and âboundary spanningâ (Bressers and Lulofs, 2010), as well as early and strong engagement of stakeholders, local capacity building and policy development (Servos et al., 2013). Nevertheless, unresolved issues remain. For example, criticisms of IWRM are prolific and conflicts between upper and lower riparian states remain common, fed by geopolitical stakes, a privileging of efficiency and securitization, the dominance of âbasin hegemonsâ, and the evasion of politics and political realities (Zeitoun, 2013). Expanding pressure on international water governance from competing uses and users of water has also seen a host of new actors (such as those in the energy sectors) shaping international water management, including the injection of new ideas on âhorizontal alignmentâ, ânexusâ management and more pluralistic basin governance (Zeitoun, 2013).
Clearly, specific institutional architectures remain necessary for the achievement of collaborative solutions to common problems in trans-boundary and trans-jurisdictional water management, particularly when questions of human rights, indigenous rights and climate change are added to the equation.
In the human rights context, for example, the increasing intersection of international water law and international human rights law has opened up new points of interaction with international water management. The UN Committee on Economic, Social and Cultural Rightsâ General Comment No. 15 on the Right to Water (UNCESCR, 2002) paved the way for the UN General Assembly to adopt a declaration on the Human Right to Water and Sanitation (United Nations General Assembly, 2010) and the UN Human Rights Council resolution on the human right to access safe drinking water and sanitation (United Nations Human Rights Council, 2010), providing strong political recognition to these rights and creating enforceable responsibilities that can empower the vulnerable, including indigenous peoples (see, e.g. United Nations Declaration on the Rights of Indigenous Peoples (United Nations General Assembly, 2007). Furthermore, progress in the field of water and sanitation supply and management was influenced by the Millennium Development Goals which sought to âhalve, by 2015, the proportion of the population without sustainable access to safe drinking water and basic sanitationâ (UN, 2002). While the goal was largely met, in 2015 some 2.5 billion people in developing countries still face physical or economic water shortage (UNDP, 2015). These statistics suggest that much work remains to be done to understand and address the interaction and coordination of human rights regimes and other areas of water law. This includes managing trade-offs between rights and other water interests (such as the environment), as well as coordinating implementation and developing win-win solutions (Gupta, 2013; Pahl-Wolst et al., 2013; Hearns et al., 2014).
Similarly, despite studies of indigenous engagement in water governance (Von der Porten and de Loe, 2013), there are numerous gaps and unresolved issues including how best to acknowledge and address real-world Indigenous goals related to self-determination and nationhood in different contexts (Von der Porten and de Loe, 2013).
The influence of climate change is also expected to compound the trans-jurisdictional governance challenges in the coming decades, requiring more adaptive and cooperative approaches that tap into local knowledge and can deal with water quality and availability concerns (Zeitoun, 2013). In short, the challenge of trans-boundary and trans-jurisdictional water governance at the international level remains a significant one (Gupta, 2013; Tujchneider et al., 2013; Hearns et al., 2014).
