The Fiji group of islands lies between 15-18 degrees South and 175 degree East to 177 degree West. It consists of over 300 islands of which about 97 are inhabited. There are small atoll limestone islands, which are very vulnerable to drought and storm surges. The bigger islands are volcanic in origin and have well established gullies and river systems. They rise to peaks of 1000 meters and have wet and dry zones.
The total landmass is about 18,272 km2. There are two main islands of Viti Levuv which is 10.4K km2 and Vanua Levu which is 5.5K km2 that comprise is 88% of the total landmass. The terrain for Fijis main island is very rugged with less than 18% of the land arable as the interior is rugged, deeply serrated and steep. The prevailing Southeast trade winds bring rains to the heavily rainforested eastern zones. Leaving dry the western leeward zone with very heavy and high intensity rainfall, soil erosion remains a very big and constant concern. The cumulative effects of erosion over the years have resulted in raised riverbeds leading to increasing incidences of flooding. These are some of the main physical features of Fiji some are serious and others are not, over all the land is very beautiful.
