Deforestation, land conversion, and urbanization fragment habitats and disrupt ecological processes. This loss of habitat threatens the biodiversity that supports food production and resilience.

b. Climate Change

Climate change poses significant challenges to biodiversity and food security. Rising temperatures, changing precipitation patterns, and increased frequency of extreme weather events can alter ecosystems and impact agricultural productivity. Many species may struggle to adapt to these changes, leading to declines in biodiversity.

c. Overexploitation

Overexploitation of natural resources, including overfishing and unsustainable farming practices, depletes biodiversity and threatens the sustainability of food systems. The loss of wild species and genetic diversity can have far-reaching consequences for food security.

d. Pollution

Agricultural practices often involve the use of chemicals such as fertilizers and pesticides, which can contaminate soil and water resources. Pollution can harm non-target species, disrupt ecosystems, and reduce biodiversity. This, in turn, can negatively impact agricultural productivity and food security.

e. Invasive Species

Invasive species pose a significant threat to native biodiversity, outcompeting local species for resources and altering ecosystems. In agricultural contexts, invasive species can reduce crop yields and threaten food production. Managing invasive species is crucial for protecting biodiversity and ensuring food security.

4. The Role of Biodiversity in Resilience and Adaptation

a. Resilience to Climate Change

Biodiversity enhances the resilience of agricultural systems to climate change by providing options for adaptation.
