Lesson summary

In Ghana, our farming is heavily dependent on rainfall, which comes in specific seasons. But what happens during the long, dry Harmattan season when we still need fresh vegetables like tomatoes, pepper, and cabbage? How do we keep our beautiful school compounds and home gardens green all year round? The answer is irrigation. Irrigation is the artificial application of water to land to assist in the growing of crops. It is a critical technology that allows us to farm productively throughout the year, ensuring food security and providing income for farmers.

Lesson notes

A. What is Irrigation?

Irrigation is the science of applying controlled amounts of water to land to help grow crops and plants. It is used to supplement rainfall, especially in areas or during times when rainfall is insufficient, such as Ghana's dry season (November to March).

Importance in Ghana: Year-Round Production: Allows farmers to cultivate crops during the dry season, leading to a consistent supply of food. Increased Crop Yields: Proper watering prevents water stress in plants, leading to healthier growth and higher yields. Food Security: Reduces our reliance on seasonal farming and the need to import vegetables from neighbouring countries like Burkina Faso. Economic Empowerment: Provides a steady source of income for farmers and creates jobs in the agricultural sector.
