Comments on ¿Conceptualization, modeling and environmental impact assessment of a natural rubber techno-ecological system with nutrient, water and energy integration¿ by Martinez-Hernandez E and Hernandez JE (2018, 185: 707¿722)

Thaler P.. 2019. Journal of Cleaner Production, 210 : p. 1063-1064.

The article ¿Conceptualization, modeling and environmental impact assessment of a natural rubber techno-ecological system with nutrient, water and energy integration¿ by Martinez-Hernandez E and Hernandez JE (2018, 185: 707¿722) is based on a compilation of published information processed through a model linking natural rubber making to latex yield in rubber tree fields. Its main conclusion is that recycling processing wastewater could increase the yield by 62%. However, the statement that nitrogen input can significantly increase latex yield is based on a wrong quotation of the only cited reference. Moreover, the outputs of the model were not validated by actual data. The published literature actually shows that possible increase of latex yield by fertilization or irrigation would be much lower than 62%, and this invalidates the model. Its conclusions can then not be considered scientifically established.
