Great work @awais307 . this saves us a lot of time.
I will go through again demand again and keep in mind to update the desalination part soon.
@Wegatriespython could revise the water impacts part in index and climate_impacts. and please read-though the cooling file if anything should be changed

| **SDG 7**: Affordable and clean energy |

Maybe we should remove SDG7 as it is not in the water module. it was just in some NAVIGATE branches, but never migrated, and now obsolete

| Basin-scale surface water availability is derived from global hydrological models that simulate the terrestrial water cycle: | ||

maybe here @Wegatriespython can jump in and directly update with what the state will be in a few months form now. basically using all the ISIMIP 3b ensemble, or just CWatM.
Vignesh can also add figures on seasonality or extremes

I need to review once we have updated numbers from Marina
| * More frequent and severe droughts | ||
| * Changes in seasonal water availability | ||

| **Direct Impacts on Energy**: |

we don't have changes in hydropower anymore, not on once-through cooling (maybe never had) or Increased cooling water requirements. also no Impacts on renewable energy resources

| Climate change affects the water-energy-land nexus through multiple pathways: | ||

| **Direct Impacts on Water**: |

Several of these things are on the hydrological model side and affect surface and groundwater.
maybe we could make it clear, and then mostly focus on the direct impacts in MESSAGE
|

| The MESSAGEix-Nexus module is typically applied within the SSP-RCP scenario framework (O'Neill et al., 2014 :cite:`oneill_2014_ssp`; Riahi et al., 2017 :cite:`riahi_2017_ssp`): | ||

| * **SSP1-2.6**: Sustainability pathway with strong mitigation |

I think from here on @Wegatriespython should edit it. not needed to repeat what is in index.rst (maybe one could be more synthetic there)
