<p>Cooperation in transboundary river basins can make water resources systems more efficient and benefit riparian stakeholders. However, in a basin with upstream and downstream stakeholders that have different interests, non-cooperative outcomes have often been observed. These can be described by a one shot prisoners’ dilemma game where non-cooperation (defection) is a dominant equilibrium strategy. However, cooperative outcomes have also been observed in several transboundary settings, such as the Lancang-Mekong River Basin (LMRB) in Asia. Such cooperation motivates our research effort to refine relevant game theoretic descriptions to account for the evolution of players’ behaviors, from conflict to cooperation. In this study, a repeated game model is proposed to analyze evolutionary transboundary cooperation. A generalized evolutionary cooperation pattern with four stages is summarized, starting with non-cooperation and ending with in-depth cooperation. The LMRB and three other typical transboundary river management case studies are chosen to validate our theoretical findings. Upstream and downstream stakeholder behaviors are analyzed for these case studies, in accordance with a game payoff matrix that accounts for incentives to cooperate. The results indicate that patience and incremental benefits can lead stakeholders to adopt a cooperative equilibrium strategy if appropriate institutional mechanisms are in place. Such mechanisms can be developed through negotiations that recognize the wide range of stakeholder interests that may influence the decision to cooperate. Our analysis suggests that game theory can provide useful insights into the conditions and institutional mechanisms that foster cooperative strategies for managing transboundary water resources.</p>

Over Exploitation

AbstractWater resources in the Middle East and North Africa (MENA region) face over-exploitation and over-pollution due to population growth, climate change and the lack of advanced water governance approaches. These challenges become more serious in transboundary river basins and may lead to conflict between riparian countries. The main objective of this paper is to assess water resources and needs at the Medjerda River Basin (MRB), shared by Tunisia and Algeria using the Water Evaluation and Planning (WEAP) system between 2020 and 2050. Four scenarios were built to assess the current and future status of the water supply and demands in both countries. The results show that water demands, and shortages are increasing, and some demand sites will face real water scarcity in the future due to climate change and development practices. Therefore, new allocation and management plans should be examined at the regional level based on real collaboration among all stakeholders.

Socio Economic Development

With the rapid development of social economy and global climate warming, scarce transboundary water resources, as one of the basic resources for socio-economic development, have increasingly become the focus of basin countries. To investigate the socio-economic impacts of different water diversion quantity from transboundary river basins, we used a system dynamics (SD) model to reflect interactions between population, water resources, and socio-economic development, and applied it to a case study in Xinjiang to simulate its change tendency from 2011 to 2030 from the temporal dimension. Then, four water diversion quantity of transboundary river basins and four alternative socio-economic development patterns were designed to comprehensively evaluate these impacts of water diversion quantity change on the socio-economy of the region along the river under different socio-economic development patterns. The results indicate that (1) there was a positive correlation between water diversion quantity and the economic output value of the region along transboundary river basins, and the marginal benefit of transboundary water resources would decrease gradually; (2) considering the difficulty of water diversion from transboundary river basins and the protection of downstream water use and ecological health of transboundary river basins, we believe that increasing the transboundary water resources by 20% was more conducive to the sustainable development of Xinjiang’s socio-economy; (3) through the comparison of dynamic evolutions of socio-economic development and water impacts under four socio-economic development patterns, it is best for Xinjiang to plan its future development in the coordinated development of economic-resource scenario. Following this scenario, not only would the total output value of the socio-economy be better than other scenarios, but this also helps to alleviate the contradiction between the water supply and demand, which expected there would be a water shortage of 1.04 billion m3 in 2029 under 20% increase in water diversion quantity. Therefore, appropriate water diversion quantity, reasonable adjustment of industrial production growth rate, reduction of water consumption quotas of different industries and domestic water quota, and improvement of collection and treatment rate for sewage should be given priority in water resources management decision-making in Xinjiang or other arid regions along transboundary river basins.

The Grupo Gestor Binacional de la Cuenca del Río Goascorán (GGBCG) was created in 2007 as an original initiative managing a shared basin in the Eastern part of El Salvador-Honduras boundary. In less than twenty years, the issue of confrontation in this border area has led to a logical approach to reconciliation and cooperation through shared management of the Río Goascorán basin. This article analyzes the ways in which the actors involved understand this cooperation. The initiative that is studied is part of a regional context that is of interest for the management of transboundary river basins. Several elements relevant to the analyzed case are addressed, including the difficulty of cross-border action and shared management, the turnover of the actors involved, and the forms of institutionalization on which the management of transboundary watersheds can be based. Spanish Este artículo se interesa en la conformación del Grupo de Gestión Binacional de la Cuenca del Río Goascorán (GGBCG) en el año 2007, como una iniciativa original de gestión de una cuenca compartida en la parte oriental de la frontera Honduras-El Salvador. El artículo muestra cómo en menos de veinte años, la problemática de enfrentamiento en este sector fronterizo dio lugar a una lógica de acercamiento y de cooperación por medio de la gestión compartida de la cuenca del Río Goascorán. También se analizan las formas en que los actores involucrados conciben la cooperación alrededor de la cuenca. El presente artículo resalta varios elementos de reflexión a través del caso analizado: la dificultad de la acción transfronteriza y de la gestión compartida; la renovación de los actores involucrados; así como las formas de institucionalización sobre las cuales puede basarse la gestión de cuencas transfronterizas que invitan a interrogarse sobre la conformación del GGBCG. French Cet article s'intéresse à la constitution depuis 2007 d'un Grupo Gestor Binacional de la Cuenca del Río Goascorán (GGBCG) comme initiative originale de gestion d'un bassin partagé sur la partie orientale de la frontière Honduras-El Salvador. L'article montre comment, en moins de vingt ans, la problématique d'affrontement sur ce secteur frontalier longtemps en litige a laissé la place à une logique de rapprochement et de coopération par le biais de la gestion partagée du bassin du Río Goascorán. Il analyse également les formes sous lesquelles les acteurs impliqués conçoivent la coopération autour du bassin. L'initiative étudiée s'inscrit dans un contexte régional d'intérêt pour la gestion des bassins hydrographiques transfrontaliers. Cet article met en lumière plusieurs éléments de réflexion à travers le cas analysé : la difficulté de l'action transfrontalière et de la gestion partagée ; le renouvellement des acteurs mobilisés ; les formes d'institutionnalisation sur lesquelles peut reposer la gestion de bassins transfrontaliers, que la création du GGBCG invite à interroger.
