LONDON, Dec 30 (Reuters) - Raw sugar futures on ICE were slightly higher on Wednesday, boosted by a weaker dollar and a more supportive macroeconomic backdrop with global equities extending recent gains, while arabica coffee prices also rose.

SUGAR

* March raw sugar was up 0.02 cents, or 0.1%, at 15.06 cents per lb at 1215 GMT, edging back towards the one-month high of 15.13 cents set on Monday.

* Dealers said a recent strengthening of the Brazilian real against the dollar had provided some support. * A stronger real decreases dollar-denominated prices in local currency terms and can curb producer sales, including hedging operations with futures.

* Dealers said an improving outlook for cane production in the key Centre-South region of Brazil following recent rains should help to keep a lid on prices.

* March white sugar rose $0.80, or 0.2%, to $412.60 a tonne.

COFFEE

* March arabica coffee rose 0.95 cents, or 0.8%, to $1.2635 per lb, also boosted by a stronger Brazilian real.

* Dealers said the market was buoyed by both investor and industry buying in fairly quiet conditions.

* March robusta coffee futures were down $5, or 0.4%, at $1,378 a tonne.

COCOA

* March New York cocoa was up $3, or 0.1%, at $2,510 a tonne.

* March London cocoa fell 5 pounds, or 0.3%, to 1,669 pounds a tonne. (Reporting by Nigel Hunt; Editing by Susan Fenton)
