收藏资源简介：
The folder contains the output data relative to the paper: Rosa, L., Citrini, A., Terlouw, T., and Mingolla, S. Water scarcity risks in ammonia fertilizer production pose a threat to global food security Contact: lrosa@carnegiescience.edu ##List of files - Figure_1.csv: Water consumption impacts (m³ water/t NH₃) for ammonia production via SMR and coal gasification pathways, including direct consumption and disaggregated supply chain components. - Figure_2.csv: Annual water consumption (m³/year) by country for ammonia production (focus on top 20 producers), disaggregated by hydrogen feedstock source (natural gas vs coal). - Figure_3.csv: Facility-level ammonia production data: location, capacity (kt NH₃/y), feedstock (natural gas vs coal), water consumption [m³ water], number of months and production losses (%) due to water scarcity under current conditions (2025), including median and interquartile ranges (25th–75th percentile). - Figure_4.csv: Estimated number of people fed per year by ammonia-based fertilizers produced with and without water scarcity, disaggregated by country and use (domestic vs export), with interquartile ranges (25th–75th percentiles). -Figures_5-6.csv: International transfers of ammonia-based fertilizer produced under water scarcity, showing export flows and associated population fed in importing countries.
