What does agrobiodiversity encompass in agriculture?

• A. Only genetic diversity within crop varieties
• B. Diversity of weather patterns across seasons
• C. Genetic, species, and ecosystem diversity in agriculture; important for resilience, nutrition, and adaptation to climate variability
• D. Diversity of marketing channels for crops

Answer: (C)

Agrobiodiversity is the variety of life involved in farming across three levels: genetic, species, and ecosystem diversity, and it supports resilience, nutrition, and adaptation to climate variability.

Genetic diversity within crops includes the different varieties and their wild relatives. This diversity provides traits like drought tolerance, pest resistance, and stable yields, and it keeps a reservoir of genes that breeders can use to adapt crops to changing conditions.

Species diversity covers the range of crop species grown and the other living components in and around the farm. Having multiple crops and beneficial organisms reduces risk from pests or weather shocks and enhances overall food security and nutrient availability.

Ecosystem diversity refers to the processes and habitats in the farming environment—soil health, pollinators, beneficial insects, microbial communities, nutrient cycling, and practices like crop rotation and intercropping. These services sustain productivity and help systems cope with climate variability.

The other options don’t capture this full, integrated picture. Focusing only on genetics misses the roles of other species and the ecosystems that support them. Weather patterns are climate factors, not biodiversity within agriculture. Marketing channels are about economics, not biological diversity. This broader view explains why agrobiodiversity strengthens resilience, nutrition, and adaptation to a changing climate.
