The red colored countries in the image are countries i consider highly vulnerable to freshwater shortages. I like to have the name of only these highly vulnerable countries appear on the map, i'd be glad to get responses on how to go about this. enter image description here

Select the Field that contains the country names from the drop-down list of Label with, and under Rendering Tab, go to Show label -> Edit:

enter image description here

and enter the following expression:

"Field_name" = 'High Vulnerable'

Where the Field_name is the field that has the classification of water vulnerability.

Pay attention to the the double quote marks for the field column name and single quote marks for the string value.

Another option:

There's full support for filtering labels by an expression. In the labeling tab choose "Rule based labling" from the top drop-down". In that window, Click on the green "+" to add a new rule. Then you can use all the expression options to add and format labels. For example, if the water availability is a numeric field, you could enter something like: "water_available" >1000000

Then, of course, choose the country name field as the label.

What's more, you can label different levels of water availability with different color or size labels...

what you want is a rule based labeling. You can use it like this: Tested in QGIS 2.14.3:
