Question

A farmer in a tropical rain forest climate currently grows tea. The farmer is debating whether to use intercropping to grow both rubber and tea. In 3–5 sentences, analyze the costs and benefits of adopting this sustainable farming practice.(4 points)

Answer 1

Intercropping rubber with tea can increase farm biodiversity, improve soil cover and microclimate, reduce erosion and pest pressure, and diversify income—thereby lowering overall risk and increasing long‑term system sustainability. It can also raise total land productivity per hectare and sequester more carbon compared with monoculture tea. However, rubber trees compete with tea for light, water and nutrients and require different management and longer lead time (several years) before latex income begins, so tea yields may fall and labor/financial complexity rises. The decision therefore hinges on careful spacing and variety choice, phased planting to smooth income gaps, and access to additional capital and market channels to cover the delayed rubber returns.
