New agri-tech tools make scarce land more productive by cutting waste and boosting yields.

As land becomes an increasingly scarce factor in agriculture, technologies like hyperspectral satellite imaging and AI analytics can offer ways of raising productivity per hectare. By pinpointing nitrogen levels across fields and combining that with weather, soil and management data, farmers can apply inputs more precisely, reducing costs and waste while increasing output. In economic terms, this boosts marginal returns on fertiliser and land, improves allocative efficiency and mitigates negative externalities like pollution. Investments in such tech can help convert agricultural inputs into higher-value crop output, strengthening the sector’s contribution to GDP.

1. Identify the four key types of economic resources (factors of production) and briefly explain each.

2. Using information from the article, explain how new agricultural technology such as hyperspectral satellite imaging can make land—a scarce economic resource—more productive.

3. What do economists mean by the term marginal returns? Discuss how agri-tech innovations might influence marginal returns in farming and assess their potential impact on both efficiency and environmental sustainability.
