Human activities such as intensive farming can negatively impact biodiversity. Various practices limit this impact, and can even improve biodiversity. These practices include polyculture rather than monoculture, crop rotation, hedgerow conservation and maintenance, predator strips at field margins, and integrated pest management and biological control.
Polyculture refers to cultivating multiple species of plant in the same area, rather than just one (monoculture). This improves biodiversity and attempts to reproduce the existing biodiversity in the environment.
Cultivating different plants together can also improve their resistance to disease, as shown by growing different rice varieties in China, decreasing disease incidence by 94%. This rendered pesticides unnecessary.
A disadvantage of polyculture versus monoculture is the increased labour needed to…
