Spatial Assessment of Greenhouse Gas Emissions and Eutrophication Potential from Livestock Manure in Bangladesh

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

This study should explore the variability in the climatic conditions over time and what is the impact on the livestock manure management practices. modeling approach for incorporating seasonal variation. What is the correlation between rainfall or temperature with the manure management?

Comments on the Quality of English Language

is there any possibility to incorporate machine learning to predict the emissions, eutrophication potential? What are the most important features that contribute or correlate with the emissions? what is the immediate and long term impact of the manure left on the pasture on the forage ?

Reviewer 2 Report

Comments and Suggestions for Authors

This article demonstrated interesting and useful results of GHG emission and eutrophication potential and susceptibility results in different regions in Bangladesh. Results will support policy and management in farms. The text is well written and I recommend publication after addressing my questions and comments.

 

General question:

When studying the leaching out of manure and estimate eutrophication potential, did you consider regional meteorology, especially annual precipitation? I wonder if regional precipitation could play a role in deposition of nutrient N and leaching out to waterbodies or soil. Perhaps you can include a bit more discussion around line 329 on regional meteorology impact, in addition to geographic specification and distribution of livestock population.

 

Minor comments:

Figure 6 is missed?

Line 376-377, this statement is confusing to me. “global case” what does it mean? You have EP values for regions in your study, how does the values compared to EP values in other regions around the world? You can even list the EP values for a few other regions. “global case” doesn’t quite make sense to me.

Line 397: you had “GHG+”. Is this a typo? or you should write out what it is.  In line 42 and 191 you have “GHGs”. The rest of the text, you have “GHG”. So please make sure they are consistent if they are the same concept.
