Online Presentations on International Water Law and Policy

Thursday, June 18th, 2015

By Gabriel Eckstein

In recent years, technology has allowed us to become more informed and engaged at greater distances. This includes viewing lectures and presentations via the Internet. I wanted to draw your attention to a number of presentations on international water law and policy that were recently posted online and that may be of interest. If any of you know of other relevant lectures online, please do let me know via the comment box below or at iwlpwebsite [at] gmail.com.

On 22 May 2015, the Strathclyde Centre for Environmental Law and Governance at the University of Strathclyde in Glasgow, Scotland, organized two lectures as part of its SCELG Seminar Series.

Entry into Force of the United Nations Watercourses Convention: Why Should it Matter

Dr. Salman M.A. Salman, fellow with the International Water Resources Association, delivered a lecture in which he outlined the progressive development leading to the adoption of the United Nations Watercourses Convention, and comprehensively explained the importance and relevance of the Convention now it has entered into force. The seminar was supported by the Scottish Government.    View the presentation here.

Transboundary Aquifers: An Interdisciplinary Conversation

Prof. Gabriel Eckstein, Professor of Law at Texas A&M University, gave a guest lecture on the challenges for transboundary aquifer law and governance. The lecture was followed by a roundtable discussion that also included an esteemed panel from the fields of hydrogeology (Prof. Robert Kalin, University of Strathclyde), human geography (Dr. Naho Mirumachi, King’s College London), and international water law (Dr. Salman M.A. Salman, International Water Resources Association).    View the presentation and roundtable here.

Over the past few years, United Nations Audiovisual Library of International Law has organized a lectures series on various international issues, including International Watercourses.

Dr. Stephen C. McCaffrey, Distinguished Professor and Scholar at the University of the Pacific McGeorge School of Law, delivered a lecture on The United Nations Convention on the Law of the Non-Navigational Uses of International Watercourses. This lecture provides an overview of the background and content of the Convention, and then examines the Convention’s influence. The lecture is available in Arabic, English, Chinese, French, Russian, and Spanish and can be viewed here.

Dr. Salman M.A. Salman presented a lecture on The Evolution, Codification and Current Status of International Water Law. The lecture describes the developments in international water law since 1911. It reviews and analyzes the work of the Institute of International Law, the International Law Association, and the International Law Commission, paying particular attention to the United Nations Convention on the Law of the Non-Navigational Uses of International Watercourses. The lecture is available in Arabic, English, Chinese, French, Russian, and Spanish and can be viewed here.

Not long before he passed away in 2013,  Ambassador Chusei Yamada, who served on the ILC during the drafting of the UN Watercourses Convention and later as Special Rapporteur for the ILC’s Draft Articles on the Law of Transboundary Aquifers, delivered a lecture on Codification of the Law on Transboundary Aquifers (Groundwaters) by the United Nations. The lecture describes how the UN International Law Commission, a subsidiary organ of the UN General Assembly with the mandate of codification of customary international law, formulated Draft Articles on the Law of Transboundary Aquifers (groundwaters) for the proper management of the transboundary aquifers in order to attain the reasonable and equitable utilization through international cooperation. The lecture is available in Arabic, English, Chinese, French, Russian, and Spanish and can be viewed here.

The Global Environmental Facility Groundwater Community of Practice, coordinated by UNESCO-IHP, has featured a of seminars on groundwater law and policy.

Webinar #1, which took place 17 October 2013, was entitled Multiple Dimensions of Groundwater Governance: What We Are Doing and What More Can We Do? The video and webinar material can be accessed here.

Professor Gabriel Eckstein: Implications of the UN Watercourses Convention for Groundwater Resources

Tuesday, August 5th, 2014

The following post by Professor Gabriel Eckstein is the seventh in the series of essays related to the entering into force of the 1997 UN Watercourses Convention (see links to all of the essays here). Professor Eckstein is a member of the law faculty at Texas A&M University, directs the International Water Law Project, and edits the International Water Law Project Blog. He can be reached at gabriel [at] internationalwaterlaw.org   or   gabrieleckstein [at] law.tamu.edu.

With Vietnam’s accession to the 1997 UN Watercourses Convention (UNWC), the global community has taken an important step toward cooperative riparian management of transboundary waters. Although most scholars and UNWC parties have focused on the surface water implications of the Convention, there is another critical component of the instrument that should not be neglected. The UWNC applies to many aquifers worldwide. The purpose of this essay is to consider the scope of the Convention in relation to groundwater resources and place it in the context of emerging international law for transboundary aquifers.

Groundwater: a hidden treasure

Groundwater is the world’s most extracted natural resource. It provides approximately 45% of humanity’s freshwater needs for everyday uses, such as drinking, cooking, and hygiene, and 24% of water used in irrigated agriculture (see here).

Not surprising, groundwater is highly transboundary. While 276 international watercourses traverse the world’s land areas, an ongoing study identified 448 aquifers and aquifer bodies traversing international political boundaries. In places like the Middle East, North Africa, and the Mexico-United States border, transboundary aquifers serve as the primary or sole source of available freshwater for human and environmental sustenance.

Despite their importance, transboundary aquifers have been comparatively ignored in cross-border water management and treaty development. While thousands of agreements have been forged for transboundary rivers and lakes, only a handful directly apply to aquifers that traverse international frontiers. As one of the few international instruments to address this topic, the UNWC provides critical recognition of the important role groundwater resources play in human progress and development, as well as the need to establish principles of law governing this “hidden” but valuable natural resource.

Applicability of the UNWC to groundwater resources

Although the UNWC clearly applies to many of the world’s groundwater resources, it is important to delineate precisely which aquifers are included and excluded from the rubric of the Convention. The UNWC defines “watercourse” to mean “a system of surface waters and groundwaters constituting by virtue of their physical relationship a unitary whole and normally flowing into a common terminus,” and an “international watercourse” as “a watercourse, parts of which are situated in different States.” Parsing out this phraseology reveals a number of important qualifications.

For an aquifer to fall within the scope of the UNWC, it must be a part of a “system of surface waters and groundwaters.” Use of the “system” criterion in the definition implies an interrelationship between multiple and interlinked water bodies. This assessment is supported and complemented by the subsequent definitional language that emphasizes the “physical relationship” and “unitary whole” of the system, and the “common” characterization of a terminus. Hence, solitary transboundary aquifers – such as independent fossil aquifers and rain-fed aquifers – are presumptively excluded from the scope of the UNWC.

It is noteworthy that subsequent to drafting the principles for the UNWC, the UN International Law Commission (ILC) submitted a Resolution on Confined Transboundary Groundwater in which it commended states to be guided by the principles of its work product in regulating independent and hydraulically unrelated transboundary groundwater resources. This progressive recommendation was not incorporated into the UNGA’s final version of the UNWC.

In addition, a textual reading of the two definitions suggests that the Convention applies where the transboundary character exists in any part of the system. Hence, a domestic aquifer is subject to the UNWC if it is hydraulically connected to a transboundary river. Similarly, an internal river would be bound by the terms of the Convention if it is linked to a transboundary aquifer. This latter scenario, however, may be subject to debate. In its Thirty-Second Session Report during its preparatory work to the UNWC, the ILC asserted that “the main stem of a river traversing or forming an international boundary” is the “core” of a watercourse. Additionally, Ambassador Chusei Yamada, who served on the ILC during the drafting of the UNWC and later as Special Rapporteur for the ILC’s Draft Articles on the Law of Transboundary Aquifers (Draft Articles), explained to this author in a private conversation that in its deliberations the ILC, and later the UNGA, never contemplated applying the Convention where the transboundary character of the system could not be found in a surface water body. Given that the qualification has yet to be considered in state practice, it remains unclear how broadly it may be interpreted.

Another criterion affecting the UNWC’s applicability to certain groundwater resources is the phrase “flowing into a common terminus.” The criterion intimates that the interlinked water resources must flow toward the same end point to be subject to the Convention’s regime. The directional flow of rivers and lakes, however, is generally described in two dimensions (from point X to point Y). In contrast, groundwater flow is defined in three dimensions because its movement is dependent on local geological conditions, which can vary throughout the aquifer. As a result, groundwater can flow toward a disparate terminal point from that of a related surface water body. Moreover, while aquifers do sometimes terminate at a single point, such as at a spring, it is more common for aquifers to discharge over an extended geographical area along the entire edge of the aquifer. Accordingly, the Convention does not apply to aquifers that do not share a common terminus with hydraulically connected rivers and lakes.

In summary, the UNWC does apply to groundwater resources. However, the Convention’s definitions narrow its relevance to domestic and transboundary aquifers that are hydraulically linked to a transboundary river or lake and that flow into a common terminus. They may also apply to transboundary aquifers that are hydraulically linked to an internal water body, so long as the interrelated surface and subsurface waters flow into a common terminus. All other aquifers are excluded from the Convention’s regime (for a more detailed analysis, see here).

UNWC, transboundary aquifers, and international law

While the UNWC is widely regarded as codifying customary international law, it draws almost exclusively from state practice related to the management and allocation of transboundary rivers and lakes. This perspective is understandable as the bilateral and multilateral cooperative experience over transboundary groundwater resources is scant in comparison. Nevertheless, many of the norms contained in the UNWC are equally (or, at least, similarly) applicable to transboundary aquifers.

A 2011 study suggests that the customary responsibilities most conspicuous in state practice include the substantive obligations of equitable and reasonable utilization and of no significant harm. The study also recognized the existence of accepted procedural duties, including: regular exchange of data and information, generation of supplemental data and information through continuous monitoring and related activities, and prior notification of planned activities. The latter obligation is considerably more general and less developed procedurally than what is contained in the UNWC. Principles contained in the UNWC, but which have yet to arise in state practice for transboundary aquifers, include norms related to ecosystem protection and pollution prevention, cooperative management mechanisms, and the settlement of disputes. In addition, the study identified groundwater-specific concepts that, while logical, have yet to emerge in state practice, including obligations related to protecting recharge and discharge zones.

In 2002, the UNGA tasked the UNILC with drafting principles of law for transboundary aquifers based on trends in state practice and customary norms. The resulting Draft Articles are now before the UNGA (see here). While the Draft Articles were modeled largely on the UNWC, there are a number of noteworthy differences. The UNWC applies to certain transboundary and some domestic aquifers as discussed above. In contrast, the Draft Articles apply to all transboundary aquifers, regardless of whether they are hydraulically linked to any other water body (surface or subsurface), and to domestic aquifers that are hydraulically related to a transboundary aquifer. In addition, the Draft Articles are tailored specifically for transboundary aquifers and include references and principles related to protecting recharge and discharge zones, ensuring the functioning of aquifers, and aquifer-related monitoring activities. If the Draft Articles proceed toward an independent legal instrument, which is yet uncertain (see here), the Draft Articles and UNWC will have to be harmonized.

Conclusion

The coming into force of the UNWC is a significant milestone in the evolution of international water law. While the Convention’s applicability to certain of the world’s groundwater resources may be limited, its growing acceptance and implementation signifies the global community’s broadening commitment to manage and utilize transboundary freshwater resources through peaceful and cooperative means. It also recognizes and affirms transboundary groundwater resources as a legitimate topic of international law.

Offshore fresh water aquifers: which law will apply?

Wednesday, January 22nd, 2014

The following post is by Renee Martin-Nagle, a Visiting Scholar with the Environmental Law Institute in Washington, DC.  Ms. Martin-Nagle can be contacted at martin-nagle [at] eli.org.

In recent years, increasingly urgent voices have been warning of a global water crisis, as the human species consistently uses more water than is sustainably available.  Pictures of parched lands, disappearing lakes and streams, and single-faucet villages have become commonplace as thirsty straws siphon life-giving water from above and below the surface of the earth.  Currently a billion people – 40% of humanity – live in water-stressed conditions, and studies predict that the situation will deteriorate rapidly in the next few years, as the agricultural sector, which already accounts for an average of 70% of global fresh water use, struggles to feed an additional billion by 2030.

Suddenly, in early December, a ray of hope appeared as a group of Australian scientists published a paper in Nature heralding discovery of vast meteoric fresh groundwater reserves off the coasts of China, Australia, North America, Greenland, Suriname, Nigeria and South Africa.  The group’s leader, Dr. Vincent Post of the National Centre for Groundwater Research and Training (NCGRT) and the School of the Environment at Flinders University, predicted that the “volume of this water resource is a hundred times greater than the amount we’ve extracted from the Earth’s sub-surface in the past century since 1900,” and went on to say that “[k]nowing about these reserves is great news because this volume of water could sustain some regions for decades.”  In spite of a cautionary message in the article that “[o]ffshore groundwater is not the answer to global water crises”, one recent headline excitedly proclaimed, “Aussie Scientists May Have Solved the Global Water Shortage Crisis.”

There are several reasons why the prospect of vast seabed aquifers should not distract us from addressing fresh water shortages.  First, the article admits that “[d[espite convincing indications of the widespread presence of offshore paleo-groundwater, direct observations remain limited.”  With very few exceptions, the presence of seabed aquifers has not been proven but is based on sporadic sampling and intensive modeling.  Technical challenges must be overcome in order to locate and access the aquifers, without introducing contamination that would forever foul the confined waters.  Further, the waters are not expected to be fresh, but rather either brackish or somewhat saline, meaning treatment will be required prior to use.  Once the quantity and quality of the contained water is determined, it must be abstracted and transported to a treatment or desalination facility that would probably be located on-shore at some distance from the wellhead.  Finally, after weighing the benefits and risks, one or more parties must be willing to invest substantial sums to find, recover and treat the water.  The investors would be unusually philanthropic if they did not expect an economic return within a reasonable time, so a mechanism for monetizing the water would have to be agreed upon.  If we accept Dr. Post’s statement that the seabed aquifers would meet our needs for only a few decades, any “solution” offered by the discovery would be short-lived at current consumption rates.

Assuming, however, that the challenges regarding accessibility and financial return could be overcome, determinations would have to be made whether jurisdiction and ownership of the water would follow domestic law, international water law, or the Law of the Sea.  Aquifers lying under the territorial sea of one nation would doubtless be governed by its domestic laws, but questions would arise for transboundary aquifers. If international water law principles were to guide ownership and use, a further determination would have to be made about which guidelines to follow.  The Convention on the Law of the Non-navigational Uses of International Watercourses (the Watercourses Convention) needs ratification by two more states to enter into force, but by its terms the Watercourses Convention only applies to aquifers with a link to a surface water system.  Since they are fossil aquifers, the seabed aquifers lack such a link to any surface water system.  The 2008 UN Draft Articles on the Law of Transboundary Aquifers (the “Draft Aquifer Articles”) include fossil aquifers within their scope, granting nations full sovereignty to aquifer formations and the water therein that lie under their borders (Art. 3).  However, the Draft Aquifer Articles have thus far received scant attention, and, in the Case Concerning the Gabčíkovo-Nagymaros Project, the International Court of Justice rejected the notion of absolute sovereignty over transboundary waters.  If the treaty void for transboundary aquifers were to be filled by adopting customary laws that have developed for transboundary surface waters, then nations sharing transboundary seabed aquifers may be expected to abide by such customary law principles as equitable and reasonable use, prevention of significant harm and exchange of information.

Alternatively, one could argue that the UN Convention on the Law of Sea (UNCLOS), which has entered into force, should serve as the prevailing set of guidelines.  In that case, a preliminary determination would have to be made as to whether water should be treated as a non-living resource such as minerals, oil and gas.  Under UNCLOS, non-living resources located within the 200-mile exclusive economic zone (EEZ) of a nation belong to that nation.  Oil and gas extraction follows the law of capture, which can result in windfall for nations with access to technology and financial resources.  An argument could be made that fresh, or even brackish, water should not be treated as a non-living resource, since water is the most vital of resources, necessary to support terrestrial life.  Indeed, the scope of the Draft Aquifers Articles initially included oil and gas along with water, but water was deemed too important to be treated in the same way as other extractive resources (see C. Yamada, Fourth report on shared natural resources: transboundary groundwaters (2007)).

The day may come when technology, financing and need will all converge to make extraction of the water in the seabed aquifers practical and even necessary.  Prior to that day, fundamental questions on legal regimes and treatment of vital resources will have to be raised and answered.

Israeli-Palestinian Agreement on Water within Sight

Wednesday, January 8th, 2014

The following post is by David B. Brooks, an Associate with the International Institute for Sustainable Development in Winnipeg, Manitoba, Canada. Mr. Brooks can be contacted at david.b.brooks34 [at] gmail.com.

Many people have said that the last thing on which Israelis and Palestinians will be able to agree is fresh water.  They are very likely wrong.  Over the past year, the two governments have been discussing a draft water agreement that was designed by Friends of the Earth Middle East (FoEME), an Israeli-Jordanian-Palestinian environmental NGO that focuses on border issues.

Failings of the Oslo Process

Since the start of the Oslo process in 1993, all attempts at the peace process have been predicated on the belief that that a peace agreement must provide a simultaneous solution to all issues (i.e., “nothing is agreed until everything is agreed”). This approach has failed.

Based on the development of a draft water agreement for FoEME by two Canadians, David B. Brooks and Julie Trottier, as well as informal discussions with the Israeli Institute for National Security Studies and the Palestinian Water Authority, the best chance for reviving the floundering peace process is to start by tackling “easier” issues, particularly fresh water.

Shared Water Resources of Israel, Palestine and Jordan

Given the Palestinian need for more water, Israel’s new water supply from large-scale desalination, and a mutual need to deal with untreated sewage, bringing water from last to first in the peace process makes economic, ecological, and, most importantly, political sense. For Palestinians, it would provide fresh water in every home; for Israelis, it would remove pollutants from rivers that flow through its main cities. The goal in sight is a Final Accord on Water, not just another interim step.

Breaking Away from the Oslo Model for Water

In addition to the broad tradeoff – more water for Palestinians; better water for Israelis -– the FoEME Proposal is put forward on the basis of two political questions: First, why wait for conclusion of a final status agreement? If, instead of fixed allocations, as with the Oslo agreements, one thinks of ongoing joint management, agreement can be reached right now.  Second, why not shift from a static to a dynamic form of agreement?  The Oslo agreement is dependent on a particular set of borders; the FoEME Proposal is adaptable to any set of borders.  The Oslo-designed Joint Water Committee can only deal with what is deemed Palestinian water; the FoEME Proposal includes joint management of all shared water, which is to say any water that flows along, across, or under the border.  The Oslo approach looks at water as primarily a supply issue; the FoEME Proposal gives as much attention to reducing demand as to increasing supply.  Finally, but perhaps most important, the Oslo agreements propose fixed quantitative allocations of water to Israelis and to Palestinians; the FoEME Proposal incorporates an ongoing review process that adjusts water allocations over time, and ensures that total withdrawals stay within sustainable limits.

One cannot share water as if it were a pie.  Transboundary agreements can divide land this way, but not water.  Water may start as rainfall, but it is then typically used over and over again, sometimes by a group of Palestinian farmers cooperating in a decentralized way, sometimes by the highly centralized Israeli water network, before it finally evaporates or flows into the sea.   With each stage of use, water quality is altered, generally for the worse.  The Oslo approach treats water as if it were both immobile and constant in quality.  The FoEME Proposal recognizes that water is mobile in space and variable in quality.

The Structure of the FoEME Proposal

Cover Page - An Agreement to Share WaterThe FoEME Proposal suggests creation of two key bodies:

  • Bilateral Water Commission replaces today’s Joint Water Committee with responsibility for all shared water (non-shared water sources would remain managed nationally).  The BWC makes key decisions on rates of extraction and of delivery of shared water, and the removal and treatment of waste water.  Its decisions are based on advice from an Office of Science Advisors (OSA) made up of professional staff appointed or seconded by the two governments.  Because it is potentially so powerful, the BWC is not allowed to make decisions independently; rather, it can only accept or reject recommendations from the OSA, but not alter them.  This format avoids giving either side the ability to leverage water issues in endless horse-trading on other, wider issues.
  • Water Mediation Board comes into play whenever the BWC finds itself unable to accept a decision of the science advisors, or if a group or community opposes its decision.  The WMB would have a wide range of tools available to guide a process of seeking resolution ranging from scientific investigations to public forums.  All of these tools must be used in as transparent a way as possible, so as to give credence to its recommendations.

 

Both the BWC and WMB should be composed of an equal number of Israeli and Palestinian representatives plus possibly one person from outside the region. If voting is necessary, the rules are designed to prevent either side from dominating the other.  For example, if the BWC has seven members, any majority decision would have to have to have the support of least one Israeli and one Palestinian.

An Israeli-Palestinian water agreement is possible – Right now!  Though not designed for any purpose other than managing shared water, it could become the first step in creating the final status agreement that has eluded negotiators for so many years.

Adoption of Regional Strategic Action Plan on the Nubian Sandstone Aquifer

Sunday, October 20th, 2013

The following post is by Raya Marina Stephan, a water law specialist and consultant, and Chair of the Publication Committee of the International Water Resources Association. Ms. Stephan can be reached at raya.stephan [at] yahoo.com.

On 18 September 2013, the Ministers in charge of water resources in the four States of the Nubian Sandstone Aquifer System (NSAS) (Chad, Egypt, Libya & Sudan), and the Chairperson of the Joint Authority for the Study and Development of the Nubian Aquifer, signed an important document, the Regional Strategic Action Plan (SAP).

The NSAS is one of the largest aquifer systems in the world, composed of non-renewable groundwater. It extends over 2,000,000 km2 and contains about 540,000 km3 of water, out of which 15,340 km3 is believed to be exploitable.

Nubian Sandstone Aquifer System (NSAS)

Nubian Sandstone Aquifer System (NSAS)

Cooperation over the NSAS dates back at least to 1989 when Egypt and Libya established among themselves a Joint Authority (JA) for the Study and Development of the Nubian Sandstone Aquifer System. In 1992, the two States adopted the agreement “Constitution of the Joint Authority for the Study and Development of the Nubian Sandstone Aquifer Waters” (see Annex 7 in the GEF Project Document).  Sudan joined the collaboration in 1996 and Chad officially affiliated in 1999.   This agreement is one of the few agreements worldwide over a transboundary aquifer. While the number of identified transboundary aquifers globally exceeds 315 (IGRAC 2012), only four have an interstate agreement. Besides the NSAS, there are: the agreement on the Genevese Aquifer (French, English), the Ministerial declarations on the North Western Sahara Aquifer System, and the agreement on the Guarani Aquifer (Portuguese, Spanish, English). It is also relevant to mention the 2009 memorandum of agreement and road map adopted by the States of the Iullemeden aquifer system (Niger, Nigeria and Mali), however little progress has been made on this effort so far.

The agreement on the NSAS, as its name indicates, is an agreement creating the Joint Authority (JA), which is intended to serve as a joint institution/commission for the management of the shared aquifer. The agreement provides the basic rules for its functioning, and its responsibilities are quite wide and large. For instance, the JA can, conduct studies on the Nubian aquifer, is entitled to develop programs and plans for the utilization of water, and can propose and execute a common policy for the development and utilization of the water resources of the aquifer. The JA can also ration the consumption of water from the Nubian Sandstone Aquifer in the member countries and, therefore, holds real management responsibilities. The agreement is, thus, more an institutional agreement than merely a water management one.

The first project (1998-2002) on the Nubian aquifer, the “Regional Strategy for the Utilization of the Nubian Sandstone Aquifer System” executed by the Center for Environment and Development for the Arab Region and Europe (CEDARE), resulted in an improved scientific knowledge of the aquifer system and the consideration of the socio-economic conditions in the riparian States. During this project, the JA acted as the Project Steering Committee and was relatively active holding yearly meetings.

In 2006, the four States engaged in a second project – Formulation of an Action Programme for the Integrated Management of the Shared Nubian Aquifer – funded by the Global Environment Facility (GEF) and executed by the International Atomic Energy Agency, with a support from UNESCO (see project website). The overall objective of the project is to establish a rational and equitable management of the NSAS for sustainable socio-economic development and the protection of biodiversity and land resources. To achieve this goal, national multidisciplinary teams in the riparian States were constituted and, with the support of a team of international experts, prepared the Shared Aquifer Diagnostic Analysis (SADA) to jointly identify, understand, and reach agreement on the priority issues, threats, and root causes of the NSAS. The SADA identifies the following key transboundary concerns:

  1. Declining water levels related to abstractions
  2. Damage or loss of the ecosystem and biodiversity that are linked to the aquifer at oases
  3. Water quality deterioration from pollution (industry, agriculture and urban)

Following adoption of the SADA, national team of experts identified the common NSAS vision and key water resource objectives as well as the ecosystems linked and dependent on the aquifer.  Finally, a common set of management actions addressing the key NSAS transboundary issues were prepared, which lead to the recently-signed SAP.  The adopted vision for the NSAS under the SAP is:

“To assure rational and equitable management of the NSAS for sustainable socio-economic development and the protection of biodiversity and land resources whilst ensuring no detrimental effects on the shared aquifer countries.”

The signing of the SAP document at the ministerial level represents an important step forward in building the cooperation process among the NSAS countries. It is the common and joint commitment to the identified shared vision for the cooperative management of the NSAS by the States and the JA, as well as the commitment to implement the actions.

Rethinking Transboundary Ground Water Resources Management: A Local Approach along the Mexico-U.S. Border

Monday, May 6th, 2013

The following post is by Gabriel Eckstein, Director of the International Water Law Project, Professor of Law at Texas Wesleyan University, and Of Counsel with Sullivan & Worcester. He can be reached at gabriel [at] internationalwaterlaw.org. This post is based on a new article by the same title.

The nearly 2,000 mile-long border between Mexico and the United States is hot and dry. Few rivers cross this arid expanse. Yet, despite the lack of visible, life-sustaining water, the region is growing – the combined border population, currently around 14.4 million, is expected to increase 40% by 2020.  The reason for this remarkable growth is ground water, more specifically, transboundary aquifers.  As many as twenty aquifers straddle the Mexico-U.S. border, many of which serve as the primary or sole source of fresh water for the border’s communities and unique ecosystems.

Map produced by the U.N. Educational, Scientific, and Cultural Organization, the World Meteorological Organization, and the International Groundwater Resources Assessment Centre suggesting the presence of 10 transboundary aquifers or aquifer systems along the Mexico-U.S. border.

Notwithstanding the undeniable importance of the region’s transboundary aquifers, neither Mexico nor the United States seem inclined to pursue a border-wide pact to coordinate management of these critical freshwater resources. While recommendations have been proffered for more than forty years, all appear to have fallen on deaf ears.  As a result, these resources are now being overexploited on both frontiers as populations and industries pump with little regard for sustainability or transboundary consequences.  Moreover, these subsurface reservoirs are being fouled by untreated wastes, agricultural and industrial by-products, and other sources of pollution.  Imminently unsustainable, the situation portends a grim future for the region.

If both federal governments are unwilling to take decisive steps, what else can be done?  Are there alternatives to a formal, comprehensive, border-wide regime that would address the complexity and multitude of issues related to the various transboundary aquifers on the border?

In a recently published article, I advocate for an alternative approach, one that sidesteps the respective federal authorities and places the burden of pursuing cross-border cooperation on the communities that so depend on these critical fresh water resources.  Essentially, I propose that subnational entities at the local and regional level pursue cooperation over transboundary aquifers in the form of informal, locally-specific, cross-border arrangements.

While this tactic challenges the national governments’ traditional monopoly over international relations, especially as they relate to transboundary natural resources, there is good reason to believe that such an approach could achieve what Mexico City and Washington, DC have failed (or declined) to do – create effective collaborative schemes for the mutual and sustainable management of the region’s transboundary aquifers.

Under the unique circumstances of the Mexico-U.S. border, informal and quasi-formal arrangements are more likely to create viable cross-border pacts that would be respected by the local communities.  The degree of interest that the national authorities have in a local issue is often directly proportional to the physical distance from the capitol.  In contrast, local decision-makers are typically better informed about local and regional cross-border concerns than federal bureaucrats, especially on issues related to the management of local fresh water resources.  Moreover, local authorities are better able to reflect the values and preferences of those most likely to be affected by a water accord with a neighboring country, which, for a local border community, is merely a short drive away.  Critically, local decision-making would likely be more sustainable, as well as responsive and adaptable to changing climatic and economic circumstances and improved knowledge, given that the local communities and their children will have to live with their decision far into the future.

In addition, a local approach to the management of transboundary aquifers makes hydrologic sense.  No two aquifers are alike; each functions as a complex and unique hydrological system.  Moreover, no two aquifers are perceived equally by overlaying communities, especially where those communities are highly dependent on the resources to meet their daily freshwater needs.  Hence, aquifers traversing the Mexico-U.S. border cannot be managed effectively through a single, comprehensive, border-wide treaty.  While a border-wide scheme may be politically convenient, such an approach could only offer very general guidelines and standards, and may prove detrimental to the sustainable management of some of the region’s subsurface waters.  Rather, an effective, sound, and equitable management plan should be tailored to each transboundary aquifer’s unique characteristics and circumstances.

One concern often raised with a local approach to the management of transboundary natural resources is the legality of such action.  As is true under most nations’ foundational instruments, both the Mexican and the U.S. constitutions recognize the national government as the sole authority empowered to deal with foreign representatives; they prohibit states, cities, and other subnational political units from entering into treaties and other formal relations with counterparts across the border.  The goal here, however, is not to create multiple, locally-specific, formal treaties throughout the border.  Rather, the goal is the development and implementation of informal or quasi-formal, locally-specific, cross-border arrangements that are implemented through cooperative understandings or memorandum of understanding, or more structured contracts for goods or services.  In the United States, while the former would be immune to Constitutional scrutiny due to their unofficial, unenforceable, and non-binding nature, the latter would be immune to the extent that the U.S. Congress has not preempted such activities under its authority to regulate interstate commerce.

Given the state of the economy, domestic and international terrorism, drug wars, and other societal and political challenges, ground water on the Mexico-U.S. border is not a priority of the Mexican and American governments.  Unfortunately, that lack of prioritization is jeopardizing the long-term viability and habitability of the border area and portends the possible downfall of many communities and ecosystems throughout the region.

The two federal governments, though, are not indispensable for developing sustainable and coordinated ground water relations on the border.  Through informal locally-specific, cross-border arrangements, frontier communities can, on their own, achieve viable cross-border pacts that will ensure the water futures of their peoples, economies, and environment.  For a more comprehensive consideration of this proposal, please see my recently published article.

Remembrance of Ambassador Chusei Yamada

Monday, March 25th, 2013

It is always sad when a colleague passes on. Somehow, it is even more sorrowful when that person was a friend to and respected by so many. On 21 March 2013, Ambassador Chusei Yamada passed away in his native Japan; and the global water community lost a great friend.

Ambassador Chusei Yamada

During his long and distinguished career, Ambassador Yamada served in various diplomatic posts, including as Japan’s Ambassador to Egypt (1989-92), India (1993-95), and Bhutan (1993-95).  He also served as an arbitrator and conciliator under the UN Convention on the Law of the Sea, and most recently, as Special Assistant to the Minister for Foreign Affairs of Japan.  While all eminent and critical roles, his work toward bridging the water divide between riparian aquifer nations may be his most significant legacy.

I met Ambassador Yamada in 2003 when I was first invited to participate on a UNESCO-organized advisory group to the UN International Commission (UNILC).  Ambassador Yamada had been selected as the UNILC’s Special Rapporteur on the topic of Shared Natural Resources and had undertaken a process to draft principles of law that would apply to transboundary aquifers.

Ambassador Chusei YamadaI had always thought it rather astute of the Commission to select someone for this role from a country that, as an island-nation, had no contiguous neighbors with whom to share transboundary fresh water aquifers. As I got to know the Ambassador, though, I realized that his selection as Special Rapporteur was even more portentous in that from the start, Ambassador Yamada poured his heart and soul into this singular challenge.

Ambassador Yamada had no formal background in ground water resources let alone training in a hard science.  He was a lawyer and a diplomat, and above all a gentleman (see Ambassador Yamada’s brief bio).  Yet, in the six years that our advisory group supported his efforts, the Ambassador became so well versed in hydrogeology and related water issues that the International Association of Hydrogeologists recognized him “for outstanding contribution to the understanding, development, management and protection of groundwater resources internationally” and awarded him their Distinguished Associate Award for 2008 (see IAH newsletter, Issue D30, December 2008, pp. 3-4).

Yamada and IAH Award

“Ambassador Chusei Yamada receiving the IAH Distinguished Associate Award 2008 at a ceremony in Geneva in July 2008. Willi Struckmeier (then Secretary General and now IAH President) hands over a special issue World Hydrogeological Map showing transboundary aquifers while Shammy Puri, Chairman of the IAH Transboundary Aquifer Resources Management Commission and now IAH Secretary General, looks on.” From: IAH newsletter, Issue D30, December 2008, pp. 3-4.

Ambassador Yamada’s contribution to the global water community cannot be overstated.  He made every effort to ensure that the principles that the UNILC drafted for the management of transboundary aquifers would be based on sound science as well as be socially and politically feasible.  As he gained new knowledge and information, he sought to pass on that education to his colleagues in the UN; as his recommendations faced challenges based on misunderstandings and cross-border mistrust, he used his diplomatic acumen to achieve compromises.

It is true that some of the nineteen draft articles that the UNILC finally transmitted to the UN General Assembly in late 2008 may not be ideal.  Nevertheless, they represent the most significant and comprehensive effort to date to address transboundary aquifers and to develop a durable legal framework for the sustainable and peaceful management of shared ground water resources.  Based on that framework, nations around the world are now beginning to reach across their frontiers to coordinate and collaborate with their neighbors over their shared aquifers (see e.g., Agreement on the Guarani Aquifer [Spanish] [Portuguese]).  Truly, we all owe Ambassador Chusei Yamada our gratitude for laying out such a propitious roadmap.

The Future of Africa’s Water Security

Sunday, May 27th, 2012

Special thanks to Kavitha Pramod for co-authoring this essay

This map, published with the original MacDonald, et.al., study, depicts potential ground water resources on the African continent. Areas in blue represent the most water-abundant areas.

Not long ago, the BBC reported (here) on vast reservoirs of ground water resources underlying the African continent and the critical use that this water could have for populations now and in the future. While the so-called “discovery” of this water wealth may be questionable (see WaterWired’s Michael Campana explaining what we already knew here), the resurgence in interest in fresh water for Africa is a critical development in itself. The MacDonald, et.al., study that started this latest brouhaha can be found here.

Africa remains one of the poorest regions in the world in terms of access to fresh water resources. A recent report by UNICEF and the World Health Organization (here) indicates that approximately 300 million people in sub-Saharan Africa are without access to safe and clean drinking water. Of the countries reported to have less than fifty-percent coverage in water supply, almost all are located in sub-Saharan Africa. Additionally, only some thirty-percent of the population in sub-Saharan Africa is blessed with improved sanitation coverage, making the region one of the most underserved in the world.

In the year 2000, the world’s major leaders came together at the United Nations Headquarters in New York to adopt the United Nations Millennium Declaration (here). The Declaration was intended to create a global partnership aimed at reducing extreme poverty throughout the world. Targets, known as the Millennium Development Goals, were set to achieve the Declaration’s aim, with a deadline for the year 2015 (see here). In sub-Saharan Africa, where some of the worst poverty and water scarcity conditions exist, only nineteen of the fifty existing countries are expected to meet the Goals’ drinking water targets by the year 2015.

This UNECA chart compares water availability for countries throughout Africa from 1990 to 2025. By 2025, all countries in the region are expected to be in a state of water vulnerability, with most being in states of water stress or water scarcity.

Of further concern for the sub-Saharan African region is that according to the United Nations, over the next ten to fifteen years, as populations continue to expand, per capita water supplies will diminish significantly to the point where available supplies will no longer be able to meet the water needs of many of the region’s nations.

Given the troubled state of Africa’s water circumstances, a renewed focus on the significant sources of ground water underlying much of the continent comes at a very important time. In addition to concentrating attention on a dire situation, it provides opportunities for the region and the global community to explore means of overcoming the water challenges facing Africa and for sustainably developing and managing these underground resources. One of these opportunities is directly tied to the fact that many of Africa’s aquifers are transboundary, underlying two or more nations. The Nubian Sandstone Aquifer System, for example, is situated below Chad, Egypt, Libya, and Sudan; the Iullemeden Aquifer System underlays Mali, Niger and Nigeria; and the Baggara Basin aquifer is underneath Central African Republic, Sudan, and South Sudan, including the parched and war-ravaged Darfur region.

As the availability of fresh water decreases across the continent, competition and tensions over transboundary resources are likely to rise. To date, however, none of the transboundary aquifer countries in Africa have entered into an aquifer sharing or management arrangement. The only transboundary aquifer-related arrangements on the continent are two rudimentary consultative and data-sharing agreements formulated for the Nubian Sandstone and Northwestern Sahara aquifers in North Africa (you can find the texts for these arrangements here and here).

More than seventy aquifers and aquifer systems in Africa have been identified as “transboundary” by the United Nations’ International Groundwater Resources Assessment Center. IGRAC’s Transboundary Aquifers of the World 2012 map is available here.

An attempt also was made to develop an extensive consultative and management regime for the Iullemeden Aquifer System. In 2009, the overlying nations (Mali, Niger and Nigeria) signed the Declaration of Bamako (here) and an accompanying Memorandum of Understanding for the establishment of a consultative mechanism for the management of the Iullemeden Aquifer System (here) whose goals were to: (1) identifying transboundary risks and uncertainties, (2) formulate joint risk mitigation and sharing policies, and (3) facilitate the sustainable development of the Iullemeden Aquifer System’s resources. While the arrangement contained rather progressive and thoughtful approaches and mechanisms, the effort appear to have stalled.

Given the levels of water stress and scarcity that African countries are currently experiencing, and which are predicted to increase rapidly, the need for action is immediate. Although ground water resources in Africa are vast and provide great opportunities for overcoming the continent’s water scarcity problems, the lack of information, technical capacity, adequate funding, and cooperation prevents many African nations from overcoming the water challenges facing them. Accordingly, it is crucial that all of Africa – from the national level to the most local community – develop programs that will expand the exploration of water resources, push for data-generation and sharing, and encourage cross-border cooperative and sustainable management initiatives. It is also critical that the United Nations, as well as the developed world, offer their assistance for this worthwhile effort.

The mere discovery of a new source of fresh water underlying one of another nation will not ensure it a future free of water scarcity. Only by cooperating and carefully and sustainably managing such resources will Africa’s nations be able to secure the much needed water for its communities and environment.

 

UNGA Adopts New Resolution on Transboundary Aquifers

Saturday, December 17th, 2011

On 9 December 2011 the United Nations General Assembly (UNGA), at its 66th session, adopted Resolution 66/104 on the “Law of Transboundary Aquifers”:

Resolution on the Law of Transboundary Aquifers

The General Assembly,

   Recalling its resolution 63/124 of 11 December 2008, which took note of the draft articles on the law of transboundary aquifers formulated by the International Law Commission,

   Noting the major importance of the subject of the law of transboundary aquifers in the relations of States, and the need for reasonable and proper management of transboundary aquifers, a vitally important natural resource, through international cooperation,

   Emphasizing the continuing importance of the codification and progressive development of international law, as referred to in Article 13, paragraph 1(a), of the Charter of the United Nations,

   Taking note of the comments of Governments and the discussion in the Sixth Committee at the sixty-third and sixty-sixth sessions of the General Assembly on this topic,1

1.    Further encourages the States concerned to make appropriate bilateral or regional arrangements for the proper management of their transboundary aquifers, taking into account the provisions of the draft articles annexed to its resolution 63/124;

2.    Encourages the International Hydrological Programme of the United Nations Educational, Scientific and Cultural Organization, whose contribution was noted in its resolution 63/124, to offer further scientific and technical assistance to the States concerned;

3.    Decides to include in the provisional agenda of its sixty-eighth session an item entitled “The law of transboundary aquifers” and, in the light of written comments of Governments, as well as views expressed in the debates held at the sixty-third and sixty-sixth sessions of the General Assembly, to continue to examine, inter alia, the question of the final form that might be given to the draft articles.

1 Official Records of the General Assembly, Sixty-third Session, Sixth Committee, 26th meeting (A/C.6/63/SR.26), and corrigendum; and ibid., Sixty-sixth Session, Sixth Committee, 16th and 29th meetings (A/C.6/66/SR.16 and 29), and corrigendum.

The Resolution, which has yet to be published separately but which is attached to a 9 November report of the UN’s 6th (Legal) Committee, follows up on the UNGA’s December 2008 action in which it welcomed the work of the UN International Law Commission (see Resolution A/res/63/124) [U.N. General Assembly Resolution on the Law of Transboundary Aquifers, A/RES/63/124 (December 2008)] in formulating nineteen draft articles on the law of transboundary aquifers along with detailed commentaries (available in English, Arabic, Chinese, French, Russian, and Spanish). At the time, the UNGA commended the draft articles to the attention of all UN member-States and placed them on the provisional agenda of the current UNGA session.

To some, adoption of the most recent UNGA resolution may be disheartening since it tables for another day discussion on the merits of the draft articles. Moreover, it postpones consideration of the final form that might be given to the draft articles (e.g., freestanding convention, protocol to the 1997 Watercourses Convention, guidelines, etc.) as well as implementation of a global framework for managing transboundary aquifers.

Nonetheless, the fact that transboundary aquifers remain on the UNGA’s agenda is a testament to the importance that countries continue to ascribe to the subject. While there may not yet be a global agreement on how shared ground water resources should be shared, there is broad recognition that transboundary aquifers are a critical and inseparable component of the global water resource system. More than one-half of humanity depends on ground water for their everyday freshwater needs including drinking, cooking, and hygiene. Moreover, in places like North Africa, the Middle East, and the Mexico-US border, transboundary aquifers serve as the primary or sole source of fresh water for human and environmental sustenance. With increasing pressures coming from climate change, population growth, and economic development, the need for a regulatory framework for cooperation and coordination over the world’s fresh water resources, and especially transboundary aquifers, continues to be an imperative.

By adopting this recent Resolution and placing the topic on the provisional agenda of its 68th session, the Assembly has emphasized the need to keep the spotlight on transboundary aquifers around the world. Moreover, by encouraging nations to enter into bilateral and regional transboundary aquifer arrangements on the basis of the draft articles, it has recognized the need for the development of norms and frameworks for cooperation over this vital resource.

While the UNGA’s approach in pursuing such a framework may be frustratingly sluggish, it might be intentional. Although the draft articles on the law of transboundary aquifers were composed with lightning speed (in contrast to the 25 years it took to craft the draft articles leading to the 1997 Watercourses Convention, the present draft articles were prepared in less than six years), they were not achieved without controversy. Among the various disputes, many nations continue to advocate that any portion of a transboundary aquifer found within a state’s territory should be subject to the principle of permanent sovereignty over natural resource (recall the UNGA’s Resolution 1803 (XVII) of 14 December 1962). This is in stark contrast to the principle of equitable and reasonable utilization, a cornerstone of modern international water law.

Accordingly, in order to prevent the wholesale rejection of the draft articles, the Assembly may be taking a soft approach to the development of global standards and norms for managing transboundary ground water resources. This approach effectively allows countries to “test run” the principles and norms proposed in the draft articles without imposing any binding obligations. And given the dearth of experience with managing transboundary aquifers, this organic and measured tactic may be justified as it will allow for the formulation of locally-specific rules and procedures that are tailored to the unique characteristics of individual shared aquifers. Ultimately, as aquifer riparians begin to utilize, abide by, and modify these norms, it is quite possible that their efforts will evolve into demonstrable state practice and, thereby, customary international law.

UPDATE: Resolution 66/104 is now available here.

Ground water, ground water, everywhere …

Friday, September 16th, 2011

In 2008, the UN General Assembly took note of the draft articles on the law of transboundary aquifers and commended them to the consideration of its member States. Those articles were the work-product of the UN International Law Commission, which was supported by an advisory group organized by the International Hydrological Programme of the UN Educational, Scientific and Cultural Organization. As indicated in that resolution, the draft articles have now been placed on the provisional agenda of the 66th Session of the UN General Assembly (UNGA), which recently commenced in New York City. The Sixth Committee (legal) of the UNGA is scheduled to examine the question of the form that might be given to the draft articles on 18 October 2011.

Not coincidentally, the most recent issue of Water International (which is guest edited by yours truly) focuses on “Strengthening Cooperation on Transboundary Groundwater Resources.” The special issue is a compilation of articles and essays on the development of international ground water law and focuses, in large part, on the draft articles. The issue also includes a number of relevant and fascinating case studies. Here is the table of contents:

Note that unless you are a member of the International Water Resources Association or pay for individual issues, you will only have access to the abstracts (note that IWRA membership is relatively inexpensive and provides access to all present and back issues of Water International).
