Description: Provides functions for analysing
        Water-Energy-Food-Nutrient-Carbon (WEFNC) nexus interactions in
        agricultural production systems. Includes functions for
        computing water use efficiency (WUE), water productivity (WP),
        and water footprint (WF) including green, blue, and grey
        components following the methodology of Hoekstra et al. (2011,
        ISBN:9781849712798). Includes energy budgeting tools for energy
        use efficiency (EUE), energy return on investment (EROI), net
        energy (NE), and energy productivity (EP). Computes nutrient
        use efficiency (NUE) metrics including agronomic efficiency
        (AE), physiological efficiency (PE), recovery efficiency (RE),
        and partial factor productivity (PFP) as defined by Dobermann
        (2007) <https://digitalcommons.unl.edu/agronomyfacpub/316/> and
        Congreves et al. (2021) <doi:10.3389/fpls.2021.637108>.
        Estimates carbon footprint (CF), greenhouse gas (GHG)
        emissions, soil organic carbon (SOC) stocks, and global warming
        potential (GWP) using Intergovernmental Panel on Climate Change
        (IPCC) Sixth Assessment Report (AR6) default values (CH4 = 27,
        N2O = 273) as reported in Forster et al. (2021)
        <doi:10.1017/9781009157896.009>. Computes composite
        Water-Energy-Food-Nutrient-Carbon (WEFNC) nexus indices,
        trade-off correlation matrices, and generates radar and heatmap
        visualizations for comparing agricultural treatments. Supports
        conservation agriculture (CA), irrigated and rain-fed systems,
        and arid and semi-arid production environments. Methods follow
        Lal (2004) <doi:10.1016/j.envint.2004.03.005> for carbon
        emissions from farm operations, and Hoover et al. (2023)
        <doi:10.1016/j.scitotenv.2022.160992> for water use efficiency
        indicators.
