Extract

One of the most isolated islands on Earth, Rodrigues in the Indian Ocean stands as a modern-day ‘morality play’ of the consequences of environmental abuse. This tiny piece of land on the fringe of the tropics, emerged as an island through volcanic action some 1.5 million years ago, and acquired its biota mainly by long-distance dispersal from the west. Rodrigues was not inhabited by any people until 1691, and since then has always been administered from Mauritius which lies 650 km to the west.

Burning, browsing, and woodcutting, have almost completely removed the indigenous forest. Close to a third of the native plant species have disappeared, and another third are on the brink of extinction. Giant land-tortoises, sea-turtles, and the Dugong, have vanished. Only two of the ten native species of land-birds survive. The endemic Solitaire was killed off even before the human population started to grow. Forest removal opened new habitats for introduced plants and animals, some of which are now highly invasive pests.

Human impact on Rodrigues has gone beyond biotic effects. Cultivation of row-crops on the hilly terrain, and the keeping of domesticated animals in excessive numbers, led to the loss of most of the topsoil by the beginning of the twentieth century. Soil removal and compaction drastically modified the hydrology of the island, and silt deposition in the lagoon has contributed to fish decline. The inherent vulnerability of the native biota, the twin hazards of cyclones and droughts that befall the island, and demographic pressure, have all exacerbated the rate and degree of resource degradation.
