How does biodiversity contribute to agricultural productivity?

Biodiversity plays a crucial role in enhancing agricultural productivity primarily through the promotion of ecosystem services. These services include a variety of ecological functions such as pollination, nutrient cycling, pest control, water regulation, and soil formation. A diverse range of plants and animals in an agricultural setting can lead to a more resilient ecosystem that is better equipped to withstand pests, diseases, and environmental changes.

For instance, having a diversity of crops can attract various pollinators, which increases crop yields. Moreover, diverse plant species can improve soil health by encouraging a wider array of soil organisms that contribute to nutrient cycling, ultimately leading to better crop growth and productivity. Additionally, natural pest control can occur as certain species may prey on pests, reducing the need for chemical pesticides and fostering a more sustainable farming practice.

In contrast, decreasing the number of crop varieties could lead to vulnerability in the system, as monocultures often struggle with pests and diseases. Reducing pest populations is indeed linked to biodiversity, but it is just one aspect of the broader ecosystem services biodiversity provides. Requiring more agricultural inputs runs counter to the efficiency and resilience achieved through biodiversity, as diverse systems can often produce higher yields with fewer inputs. Thus, promoting ecosystem services through biodiversity reflects its essential role in
