This website describes the data sources and processing to get the results presented in Chapter 5 of Starck (2024).
It assesses, for a panel of countries, the potential of nitrogen in human excretions if it was used as fertilizers. For this, it relies on FAOSTAT data.
In the tab Prepare FAOSTAT data, I present and pre-process the FAOSTAT data that I use (about livestock manure, use of mineral fertilizers, crop nutrient balance, and food supply estimates).
In Results, I present the comparison between N in human excreta and several N fertilization sources: manure, synthetic fertilizers and total nutrient inputs to croplands.
The source data, output data, and code to generate it is accessible on this github repository, which produced this website. It is also associated to a permanent repository on zenodo at https://doi.org/10.5281/zenodo.14591081.
