explain the role of terrace cultivation on hilly areas
Terrace (agriculture) In agriculture, a terrace is a piece of sloped plane that has been cut into a series of successively receding flat surfaces or platforms, which resemble steps, for the purposes of more effective farming . This type of landscaping, therefore, is called terracing. Graduated terrace steps are commonly used to farm on hilly or mountainous terrain. Terraced fields decrease both erosion and surface runoff, and may be used to support growing crops that require irrigation, such as rice. The Rice Terraces of the Philippine Cordilleras have been designated as a UNESCO World Heritage Site because of the significance of this technique.[1]
Upland and lowland Upland habitats are cold, clear, rocky, fast-flowing rivers in mountainous areas; lowland habitats are warm, slow-flowing rivers found in relatively flat lowland areas, with water that is frequently coloured by sediment and organic matter.
