“…This is particularly true when it comes to tracking trends consistently across time, space and sectors. For example, SEEA Central Framework water accounts can provide consistent, structured data describing watershed-scale trends in water use and water quality [ 45 ], while SEEA Ecosystem Accounting data can track changes in related ecosystem services such as the regulation of sediment retention [ 46 , 47 ]. These data are often not measured or monitored by individual businesses, yet could be useful for informing corporate risk analysis related to ecosystem conditions upon which many different businesses, sectors and/or communities may depend.…”

Nature loss threatens businesses, the global economy and financial stability. Understanding and addressing these risks for business will require credible measurement approaches and data. This paper explores how natural capital accounting (NCA) can support business data and information needs related to nature, including disclosures aligned with the Taskforce on Nature-related Financial Disclosures recommendations. As businesses seek to measure, manage and disclose their nature-related risks and opportunities, they will need well-organized, consistent and high-quality information regarding their dependencies and impacts on nature, which few businesses currently collect or track in-house. NCA may be useful for these purposes but has not been widely used or applied by businesses. National NCA guided by the U.N. System of Environmental-Economic Accounting may provide: (i) a useful framework for businesses in conceptualizing, organizing and managing nature-related data and statistics; and (ii) data and information that can directly support business disclosures, corporate NCA and other business applications. This paper explores these opportunities as well as synergies between national and corporate natural capital accounts. In addition, the paper discusses key barriers to advancing the wider use and benefits of NCA for business, including: awareness of NCA, data access, business capabilities related to NCA, spatial and temporal scales of data, audit and assurance considerations, potential risks, and costs and incentives. This article is part of the theme issue ‘Bringing nature into decision-making’.

“…This is critical for understanding changes in water use and water use efficiency in response to economic transformations, such as the rapid expansion of the electronics industry. 15 A prior study employed the System of Environmental-Economic Accounts for Water (SEEA-Water) to develop accounts for water use and productivity (defined similarly as WUE) in the US from 2000 to 2015, showing a 65−73% increase in the overall national water productivity. 16 It recognized and made efforts to partially address the issues of incomplete water data availability and the overly generalized water use categories in reporting.…”

“…Even within the United States, where water data are relatively comprehensive with decades of records, there exists significant opportunities for enhancements in data collection and reporting that would facilitate more precise associations of water use with specific activities at more disaggregated levels.

United Nations Sustainable Development Goal 6 tackles the long-neglected economic dimension of water utilization by monitoring nations' water use efficiency (WUE). However, it is imperative to emphasize the need for consistent spatial-temporal subnational WUE estimates, rather than relying solely on recent national trends, which can obscure crucial water use concerns and improvement opportunities. Here, a time series analysis of national, state, and sectoral (e.g., industrial, service, and agriculture) WUE from 1980 to 2015 was developed by compiling the most comprehensive and disaggregated water and economic data from 3243 US counties and 50 US states. The US total WUE increased by 181% from 16.2 (1985) to 45.6 USD/m 3 (2015), driven by service sector WUE enhancements. The increased industry and service WUEs in most states were more strongly correlated with decreased per capita water withdrawal than with economic growth. Simultaneously, reductions in agriculture WUE were observed in 18 states potentially because of the complicated interaction of diverse factors specific to local communities. Expanding WUE gaps between affluent and less affluent states, and persisting WUE gaps between water-abundant andwater-scarce states highlight the need to advance policies to support under-resourced communities in effective water planning and water pricing for advancing equitable development.

In the present study, the impact of Land Use and climate change on the flows of River Ravi has been assessed through GIS remote sensing and applying the hydrological model at the catchment scale. A Soil and Water Assessment Tool (SWAT) model has been applied to simulate the hydrological response of River Ravi considering the current and future Land Use and climate changes. The model was calibrated and validated for the periods of 1999–2002 and 2003–2005, respectively. The good fit values of NSE, R2, and PBIAS for the calibrated model are 0.85, 0.83, and 10.01 while for the validated model are 0.87, 0.89, and 7.2. By supervised classification techniques current and future Land Use maps were prepared for the study area using Landsat images and the TerrSet model for the prediction of future change in the built-up area. The result showed that the built-up area increased by 15.8% over the period 1990 to 2020 and the Future built-up area is expected to increase by 31.7% over the period 2020–2100. Climate change projections of precipitation and temperature under two Shared Socioeconomic Pathways SSP2 and SSP5 have been carried out, and statistical downscaling has been performed by the CMhyd model. The result indicated that over the period 2016–2100, precipitation is expected to increase by 10.9% under SSP2 and 14.9% under SSP5. Similarly, temperature is expected to increase by 12.2% under SSP2 and 15.9% under SSP5. The result of the SWAT model considering the increased precipitation over the period 2016–2100 shows the inflows of River Ravi are expected to increase by 19.4% by SSP2 and 25.4% by SSP5 in Scenario I. Similarly, the inflows of River Ravi are expected to increase by 22.4% by SSP2 and 28.4% by SSP5 in Scenario II. Based on the past observed data, it is found that average Groundwater depth decreased at a rate of 0.8 m per annum over the period from year 1996 to 2020.
