Learning Objectives

Indicator: 2.1.3.LI.2 - Describe the modern and efficient ways of crop irrigation

By the end of the lesson, learners can:

Define modern irrigation and distinguish it from traditional/rainfed methods of supplying water to crops.
Describe at least four modern irrigation systems (drip, sprinkler, centre pivot, and subsurface irrigation) and explain how each delivers water to the crop.
State the advantages and disadvantages of each modern irrigation system in relation to water use, cost, and crop suitability.
Identify the crops (cereals, legumes, tuber crops, vegetables, and ornamentals) best suited to each irrigation method based on local conditions.
Demonstrate, using a simple classroom or field demonstration, how a drip or sprinkler system delivers water more efficiently than watering by hand.
