The delineation of the world’s international river basins has not been undertaken by any formal body since 1978. Researchers with the Transboundary Freshwater Dispute Database have attempted to fill this void through the 1999 Register, with online updates and currently with the present study. This current register delineates 310 international river basins, reflecting changes in political boundaries and increased data quality. These basins are shared by 150 countries and disputed areas, cover 47.1% of the Earth’s land surface and include 52% of the world’s population. This paper lists all international river systems, their basin areas, their riparian states and their respective territorial percentages.

Much has been written on hydropolitics, or on the interplays between transboundary water resource issues and politics. This article builds on recent calls for more research on the role of discourses in shaping hydropolitics. We propose a conceptual framework, inspired by critical discourse analysis, for the systematic investigation of how discursive practices construct and enact actors’ power positions in transboundary basin governance. Our framework’s added value lies in the typology of discourses we develop – that is, dominant, institutionalized, hegemonic and sanctioned – for a more precise analysis of discursive hydropolitics. We formulate a research agenda to operationalize our perspective on discursive hydropolitics and lay the groundwork for future empirical research.

The forest transition model posits that as a society advances to later stages of demographic and economic transitions, reforestation begins to outpace deforestation. However, this concept was constructed on endogenous factors within more developed nation‐states, giving scant attention to exogenous factors that today's globalising world has made increasingly relevant. Further, the transition period between net deforestation and net reforestation needs to be better understood, particularly in developing countries that may be going through a forest transition. Here we address these issues in the Cockpit Country region of Jamaica through a remote‐sensing analysis of forest‐cover change from 1987 to 2011. Our findings suggest this region is in the turnaround period of the forest transition attributable to changes in demographics and the Jamaican agricultural sector, which has been decimated by neoliberal economic policies leading to agricultural land abandonment. This study contributes to the development of the forest transition concept through adding a Caribbean case study inclusive of exogenous factors related to the changing global political economy and addressing the mechanisms at work during the forest transition turnaround.

Thermoelectric power plants account for approximately 40% of total U.S. water withdrawals each year. In 2022, 48.5 trillion gallons of water were withdrawn for cooling systems in electricity production, of which 962.9 billion gallons of water were consumed and no longer available for downstream use. Conventional steam coal plants, in particular, withdrew 18.3 trillion gallons of water for once-through and recirculating cooling systems in 2022 while contributing to 19.7% of total U.S. net electricity generation. As coal-fueled electricity production becomes less competitive, cases of coal-to-gas retrofits occur to avoid stranded assets. Two retrofitting methods are adopted in practice: coal-fired power plants are repurposed and replaced by natural gas combined-cycle plants, or the boiler of a coal plant is converted to burn natural gas. In this study, we construct panel data and employ an event study framework to examine changes in water withdrawal, water consumption, water discharge, and carbon emissions resulting from coal-to-gas retrofits in the continental United States from 2013 to 2022. Seventeen coal-fired power plants have been replaced with natural gas combined-cycle plants, and 167 coal steam units in 85 plants have undergone coal-to-gas boiler conversions. We find a sharp and sustained reduction in water withdrawal of 40.2–53.9 thousand gallons per megawatt-hour of net electricity produced when a coal plant transitioned to a natural gas combined-cycle plant. Water discharge was also reduced by 30.7 thousand gallons, and carbon emissions decreased by 0.59 short tons per megawatt-hour. Yet, boiler conversion did not lead to statistically significant changes in per megawatt-hour water withdrawal, water consumption, water discharge, or carbon emissions. Spatial assessment further informs resource planning of projected water-stressed regions, as 204.6 gigawatts of coal-fired power plants remain operable in the United States in 2022. Fuel transition should adopt a nexus approach and account for the interdependence between water resources and electricity production to realize sustainable development commitments.
