Novel cropping system strategies in China can increase plant protein with higher economic value but lower greenhouse gas emissions and water use

This database contains the average crop residue, manure nitrogen, manure organic carbon, net greenhouse gas emissions, and cropland area for 17 cropping systems at prefecture level during the period 2014-2018. In addition, it contained the changes of net greenhouse gas emissions caused by the optimization at prefecture level and province level.

    We also shared the key code for optimizing cropping systems at prefecture level and provided the all data. Users can run it the Matlab platform.
