wefnexus: Water-Energy-Food-Nutrient-Carbon Nexus Analysis for Agronomic
Systems
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.
