Lesson notes

Learning Objectives

Indicator: 1.4.1.LI.2 - Discuss increasing drought, pestilence and decreasing crop yields.

By the end of the lesson, learners can:

Define drought, pestilence, and decreasing crop yields in their own words, giving at least one local example of each.
Explain the causal chain linking rising temperatures, drought, pestilence, and falling crop yields, using evidence from Ghanaian farming systems.
Analyse how the combined effects of drought and pestilence threaten food security and rural livelihoods in Ghana, using strategic reasoning to weigh multiple factors.
Discuss adaptive strategies that Ghanaian farmers can adopt to reduce the impact of drought and pestilence, and evaluate their feasibility in different ecological zones.
Present a group report on observed or reported effects of drought and pestilence in a Ghanaian farming community, drawing on internet research and personal knowledge.
