IGCSE Geography Agricultural Systems Practice Test

Intercropping directly changes how crops are grown to boost output and resilience. By planting two or more crops together, farmers can use light, water, and nutrients more efficiently and reduce risks. For example, a nitrogen-fixing legume can enrich soil for nearby cereals, and the mix of crops can disrupt pests and spread harvest risk, leading to higher and more stable yields. Other options focus on selling (improving markets), reducing post-harvest losses (better storage), or bringing in food from outside (increasing imports) rather than changing farming practices to raise production. Intercropping is the practice that most directly addresses production difficulties by enhancing on-farm productivity.
