What should I do about this?

Dont know how it happened.

I know the best option is to replace the rim but unfortunately I dont have that luxury living here in Pakistan nothing is available. Closest trip abroad in 7 months away and I need a temporary (but a reliable) fix for this.
I was also about to change my brake pads. should I replace them because I think they'll wear off quite quickly now.

    If it's just a scuff you can stone it out. If the rim is bent inward, remove the tyre and tube and carefully use an adjustable spanner to correct it.

    If it is bulging outward, get 2 pieces of flat steel to cover about 2 inches of the brake track on BOTH sides of the rim.
    Remove or deflate the tire and carefully use a pair of vice-grip pliers to squeeze on the steel flats to press the bulge inward a little at a time.
    Don't use pliers without the steel flats - it will put too much force on a small area of the rim.
    The flats distribute the force to prevent more damage.
    STOP when the rim is 'good enough'.

    It looks like a rather big chip, to which there is no cure... you can smooth the area with very fine sand paper, but you can't remove it

    Looks like a chunk out of the rim which is deeper than the wear indicator = dangerous. Get a new rim - do they not deliver bike parts to Pakistan? Can't believe none of the numerous world wide retailers will.

    The Rim is not bent inwards or outwards. It has just left a depression on the rim. I think I just have to smoothen out the corners and ride this thing until I get a new rim.

    Obviously its your call but ...

    In terms of the integrity/safety of the rim whether its bent or not is not all there is to consider. More dangerous than a bend is removal of rim material. From the picture it is clear that what you call a depression has removed some of the rim metal. In case you don't realise that black line around the rim is the wear indicator for the brake track. In the picture that line is gone so some of the rim metal has been removed to a thickness deeper than the brake track wear indicator. Once the rim has worn to the depth that the wear indication line is gone the rim should be replaced as it is not safe. If its a rear wheel then rim failure and a blow out may only cause you the inconvenience of an interrupted ride but if its a front wheel then rim failure and a blow out could cause a serious accident.
