Water Harvesting and Catchment Systems

The video tutorial on Elim TV, led by Mr. W, covers methods of water harvesting in agriculture. The lesson is part of Form One work, lesson 33, focusing on water supply, irrigation, and drainage. The tutorial explains five methods: dam, weir, roof catchment, rock catchment, and micro catchment. Each method is described in detail, highlighting its purpose and application on a farm. The lesson concludes with an assignment to explain three water harvesting methods and provides references and contact information for further learning.
