In a small saucepot combine the sugar and water, and cook over low heat until sugar is dissolved.
Pour into a bowl containing the lemon and lime juice. Add the papaya, candied ginger, and mint. In a separate bowl toss raspberries and blackberries.
Place papaya mixture into each serving bowl. In the center place a spoonful of mixed berries and garnish with lemon zest.
