Strategies for Landslide Risk Treatment Landslide risk treatment is the ultimate objective of the risk management process which aims to mitigate the effects of the hazard. This encompasses a five-pronged strategy comprising: i) Treating vulnerable slopes and existing hazardous landslides. ii) Restricting development in landslide-prone areas. iii) Preparing codes for excavation‚ construction and grading. iv) Protecting

1. INTRODUCTION: The significance of environmental factors to the health and well-being of human populations’ is increasingly apparent. Environment pollution is a worldwide problem and its potential to influence the health of human populations is great. Pollution reaches its most serious proportions in the densely settled urban-industrial centers of the more developed countries .

Main causes: Natural hazards are excluded as a cause of land degradation‚ however human activities can indirectly affect phenomenon such as floods and bushfires. Overgrazing by livestock can lead to land degradation. Land clearances such as clear cutting and deforestation have a big impact on Nauru. Agricultural reduction of soil nutrients through poor farming practices are also a major cause of
