Management of transboundary rivers will be one of the great political and environmental challenges of the 21st century if knowledge of conflict and cooperation is not fully developed. Transboundary river conflict and cooperation are critical for the sustainable development of river basins, regional security, and stability, and have significant scientific and practical implications. The construction of a dataset of transboundary water events – individual conflictive or cooperative interaction between riparian –provides important data support and factual basis for the study of transboundary rivers. However, the most representative research, the Transboundary Freshwater Dispute Database, is built by means of manual reading for information extraction, thus difficult for fast updating, also does not cover the global changes in the past decade. This research aims to build a methodological framework for news media datasets tracking of conflict and cooperation dynamics on transboundary rivers, provide mass of relevant data for the research of transboundary rivers in the globe, prepare a potent research toolkit, lay a solid foundation for further data mining research, and better suit the big data age. In order to test the effectiveness of the methodological framework and toolkit for dataset construction, this research analyses the word frequency and themes of the articles in datasets. The results show that the datasets built by this framework can reflect comprehensive themes of transboundary water conflict and cooperation. Through the analysis of media activity in different river basins, it is possible to get a global overview of the participation of countries located within and outside of the basin in transboundary water issues.

The management of transboundary rivers will be one of the great political and environmental challenges of the 21st century if knowledge of conflict and cooperation is not fully developed. Transboundary river conflict and cooperation are critical for the sustainable development of river basins, regional security, and stability and have significant scientific and practical implications. The construction of a dataset of transboundary water events – individual conflictive or cooperative interaction between riparian regions – provides an important data support and a factual basis for the study of transboundary rivers. However, the most representative research, the Transboundary Freshwater Dispute Database, is built by means of manual reading for information extraction, is, thus, difficult for fast updating, and also does not cover the global changes in the past decade. This research aims to build a methodological framework for news media datasets to track conflict and cooperation dynamics on transboundary rivers, provide a mass of relevant data for the research of transboundary rivers on the globe, prepare a potent research toolkit, lay a solid foundation for further data mining research, and better suit the big data age. In order to test the effectiveness of the methodological framework and toolkit for dataset construction, this research analyses the spatial coverage, both in terms of continental and national, temporal coverage from 1953 to 2019, and content coverage and conducts relevance screening of the articles in the four representative river basins in the datasets. The results show that the datasets built by this framework can capture comprehensive content of transboundary water conflict and cooperation in both spatial and temporal coverage with acceptable data quality.

The transboundary Lancang–Mekong River basin has experienced dynamics of cooperation over the past several decades, which is a common emergent response in transboundary coupled human–water systems. Downstream countries rely on the Mekong River for fisheries, agriculture, navigation and ecological services, while upstream countries have been constructing dams to generate hydropower. The dam construction and operation in upstream countries have changed the seasonality of streamflow in downstream countries, affecting their economic benefits. More recently, cooperation between upstream and downstream countries has been enhanced throughout the river basin. In this study, we introduce a quantitative socio-hydrological model to simulate hydrological processes, reservoir operations, economic benefits, policy feedbacks and therefore dynamics of cooperation within the Lancang–Mekong River basin. The model reproduces the observed dynamics of cooperation in the basin revealed by sentiment analysis of news articles. Hydrological variability such as droughts and human activities associated with reservoir operations affect dynamics of cooperation between the riparian countries, with importance attached to indirect political benefits of upstream playing an important role in the enhancement of cooperation. In this way, our study generated understanding of emergent cooperation dynamics in this transboundary river basin, and the socio-hydrological model used here provides a useful new framework to investigate and improve transboundary water management elsewhere.

In a recent editorial in the journal Nature Sustainability, the editors raised the concern that journal submissions on water studies appear too similar. The gist of the editorial: "too many publications and not enough ideas." In this response, we contest this notion, and point to the numerous new ideas that result from taking a broader view of the water science field. Drawing inspiration from a recently hosted conference geared at transcending traditional disciplinary silos and forging new paradigms for water research, we are, in fact, enthusiastic and optimistic about the ways scientists are investigating political, economic, historical, and cultural intersections toward more just and sustainable human-water relations and ways of knowing.

International audience ; The Sustainable Development Goals (SDGs) of the United Nations Agenda 2030 represent an ambitious blueprint to reduce inequalities globally and achieve a sustainable future for all mankind. Meeting the SDGs for water requires an integrated approach to managing and allocating water resources, by involving all actors and stakeholders, and considering how water resources link different sectors of society. To date, water management practice is dominated by technocratic, scenario‐based approaches that may work well in the short term but can result in unintended consequences in the long term due to limited accounting of dynamic feedbacks between the natural, technical, and social dimensions of human‐water systems. The discipline of sociohydrology has an important role to play in informing policy by developing a generalizable understanding of phenomena that arise from interactions between water and human systems. To explain these phenomena, sociohydrology must address several scientific challenges to strengthen the field and broaden its scope. These include engagement with social scientists to accommodate social heterogeneity, power relations, trust, cultural beliefs, and cognitive biases, which strongly influence the way in which people alter, and adapt to, changing hydrological regimes. It also requires development of new methods to formulate and test alternative hypotheses for the explanation of emergent phenomena generated by feedbacks between water and society. Advancing sociohydrology in these ways therefore represents a major contribution toward meeting the targets set by the SDGs, the societal grand challenge of our time.
