The Mean

The Agricultural Water Stress indicator identifies agricultural water stress of agricultural land under irrigation. It is calculated as the mean annual irrigation water consumption divided by the sum of mean annual runoff (MMR).

The Impact

The Human Water Stress indicator deals with the quantity of water available per person per year relative to the internal and upstream area water supplies, on the premise that the less water available per person, the greater the impact on human development and well-being, and the less water there is available for other sectors.

The Impact

Water, in most of the transboundary river basins, is a bone of contention among their riparian states. Taking this into account, this article assessed the monthly impact of upstream water withdrawal on the water security of middle stream and downstream sub-basins at a country-basin mesh spatial resolution. Roughly 2.18 billion people in 442 sub-basin areas experience water stress intensification by less than 1% throughout the year. In addition, 2.12 billion people in 336 sub-basin areas experience water stress level change, from no water stress to one of the water stress categories, for at least one month as the result of upstream withdrawal. Even though there is a clear upstream impact in many of the basins, water disputes with severe social, economic, political, and environmental consequences are nonexistent. This might be an indication that grave water disputes are the result of complex socio-economic and political interactions, not merely because of water deficits due to upstream water withdrawal. Therefore, understanding this relationship is crucial in identifying inflection points for water conflicts within 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.

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.

L'initiative étudiée s'inscrit dans un contexte régional d'intérêt pour la gestion des bassins hydrographiques transfrontaliers.

Abstract. There is a growing recognition among water resource managers that sustainable watershed management needs to not only account for the diverse ways humans benefit from the environment, but also incorporate the impact of human actions on the natural system. Coupled natural–human system modeling through explicit modeling of both natural and human behavior can help reveal the reciprocal interactions and co-evolution of the natural and human systems. This study develops a spatially scalable, generalized agent-based modeling (ABM) framework consisting of a process-based semi-distributed hydrologic model (SWAT) and a decentralized water system model to simulate the impacts of water resource management decisions that affect the food–water–energy–environment (FWEE) nexus at a watershed scale. Agents within a river basin are geographically delineated based on both political and watershed boundaries and represent key stakeholders of ecosystem services. Agents decide about the priority across three primary water uses: food production, hydropower generation and ecosystem health within their geographical domains. Agents interact with the environment (streamflow) through the SWAT model and interact with other agents through a parameter representing willingness to cooperate. The innovative two-way coupling between the water system model and SWAT enables this framework to fully explore the feedback of human decisions on the environmental dynamics and vice versa. To support non-technical stakeholder interactions, a web-based user interface has been developed that allows for role-play and participatory modeling. The generalized ABM framework is also tested in two key transboundary river basins, the Mekong River basin in Southeast Asia and the Niger River basin in West Africa, where water uses for ecosystem health compete with growing human demands on food and energy resources. We present modeling results for crop production, energy generation and violation of eco-hydrological indicators at both the agent and basin-wide levels to shed light on holistic FWEE management policies in these two basins.
