In other countries on the Continent, communities are testing the re-introduction of extinct grass species, the deployment of rainwater harvesting, rotational grazing and the simple anti-erosion techniques as anti-desertification strategies.

Rainforest rehabilitation in every sense
Sophisticated sensors that measure leaf wetness, soil moisture and temperature are helping rehabilitate rainforest in the Springbrook World Heritage precinct in south-east Queensland. The CSIRO sensors are being used to uncover the microclimatic conditions favourable for rapid natural regeneration of degraded rainforest environments. A network of ten sensor nodes, connected wirelessly, has been sampling parameters such as rainfall, humidity, temperature, soil moisture and the amount of available light inside the forest every five minutes since May 2008. Over the next two years, ... |
