Improving Response Measure for Sediment Disaster in Watershed
* Improving Response Measure for Sediment Disaster in Watershed

     Taiwan is an island located on the earthquake belt of the Pacific Rim. Due to the movement of tectonic plates, Taiwan has fragile a geological formation made up of a wide variety of rock types. There are numerous faults and the island suffers frequent earthquakes. Every year, Taiwan is also hit by typhoons, heavy rain, or torrential downpours brought by southwestern air currents related to typhoons. Taiwan’s terrain is dominated by high mountains and short, swiftly-flowing rivers. Landslides of various types are frequent. In recent year, climate change has brought more frequent heavy rains, and the severity and affected area of landslide disasters has increased. Due to downpours of greater intensity and the cumulative rainfall, disasters directly related to hydrological events have become more frequent, highlighting the urgency and importance of soil and water conservation efforts. 


     In the past, Taiwan experienced disasters that could be categorized as simple flooding or sediment disasters. This has changed, with disasters being predominantly a combination of the two. Because of this, soil and water conservation efforts in watershed must take a comprehensive approach, which can be expressed as “integrated river basin management.” Under the umbrella of “people foremost, sustainable development” and the spirit of the nation’s Key Infrastructure Projects, the Bureau is promoting the Water and Green Construction Plan, which incorporates comprehensive disaster prevention measures for slopeland areas with proper respect toward nature and the recovery of the land.
