Reviewer 1 Report
This paper presented a study on geospatial assessment of MARPS in Punjab, Pakistan. This paper is well organized and the finding can provide a draft understanding of MAR. My comments are as follows.
(1) The general hydrogeology conditions should be introduced in short, including the current status of groundwater use, the hydraulic conductivities, and aquifer thickness. For MAR, no any detailed information about aquifer is discussed.
(2) It is not clear how you choose the important factors and how you decide the value of weight. Meanwhile, the accuracy of each factor should be presented and how the accuracy affects the final evaluation should be discussed.
(3) You compared the MARPS from three methods in Figure 5. The distribution of five classes from three methods is different. However, the reason and rationality are not discussed.
(4) I wonder the relation between MARPS and the change of groundwater level. As studied, the good suitable zones are located at the northeastern side of the study area. However, the serious groundwater level drawdown is located at the middle region. Normally, the farmers have best practice for finding the wells for irrigation. The reason should be further explained.
(5) Since some observation data is long term, it is suggested to further discuss the reasonability of the results in some sites.
(6) There are some grammar errors and the writing should be checked carefully. For example, the sentences in Lines 206-208.

Reviewer 2 Report
This research developed a method to identify suitable groundwater recharge areas based on available data (GIS layers). My main comment: depth to water table (DWT) is a key factor for groundwater recharge. Therefore, DWT data (at least some information about DWT) should be presented or even included in the analysis.
Line 141-144: Explain why these factors are selected for analysis. Data availability? Do they control the aquifer recharge? How? And literature review on the controls of these factors on recharge.
The key component of this research is Table 3, and the determination of weights for each factor needs to be clearly elaborated. It seems Table 2 is important for this. However, Table 2 is missing.
None.
