Monoculture
In agriculture, monoculture is the practice of growing one crop species in a field at a time. Monocultures increase ease and efficiency in planting, managing, and harvesting crops short-term, often with the help of machinery. However, monocultures are more susceptible to diseases or pest outbreaks long-term due to localized reductions in biodiversity and nutrient depletion. Crop diversity can be added both in time, as with a crop rotation or sequence, or in space, with a polyculture or intercropping. Monoculture practices have been linked via several pathways to negatively impact human health from a One Health perspective. These links include but are not limited to environmental degradation, increased pest and disease outbreaks, greater pesticide/herbicide use, and reductions in dietary diversity (associated with diet-related disease burden including cardiovascular disease and diabetes).
Monocultures appear in contexts outside of agriculture and food production. Grass lawns are a common form of residential monocultures. Several monocultures, including single-species forest plantations, have become increasingly abundant throughout the tropics following market globalization, impacting local communities.
Genetic monocultures refer to crops that have little to no genetic variation. This is achieved using cultivars, made through processes of propagation and selective breeding, and can make populations susceptible to diseases which can rapidly spread across large areas. This widespread susceptibility ultimately endangers food security for regions dependent on such food supply.
Agroecological practices, silvo-pastoral systems, and mixed-species plantations are common alternatives to monoculture that help preserve biodiversity while maintaining productivity. These practices offer resilience to possible negative human and environmental health impacts.
