Agro-biodiversity

Definition

Agro-biodiversity refers to the variety and variability of animals, plants, and microorganisms that are used directly or indirectly for food and agriculture. This includes the genetic diversity of crops and livestock, as well as the ecosystems that support them. Understanding agro-biodiversity is crucial because it helps maintain food security, supports ecosystem health, and enables agricultural resilience against pests and climate change.

5 Must Know Facts For Your Next Test

1. Agro-biodiversity is vital for food security as it provides a diverse range of crops and livestock that can adapt to changing environmental conditions.
2. Higher levels of agro-biodiversity are associated with improved ecosystem services such as soil fertility, pest control, and pollination.
3. Loss of agro-biodiversity can lead to increased vulnerability of food systems to pests, diseases, and climate change impacts.
4. Traditional farming practices often enhance agro-biodiversity by preserving local varieties and indigenous species that might not be used in modern agriculture.
5. Efforts to conserve agro-biodiversity include seed banks, community gardens, and policies aimed at promoting sustainable land use.

Review Questions

• How does agro-biodiversity contribute to food security and agricultural resilience?
  • Agro-biodiversity contributes to food security by ensuring a diverse array of crops and livestock that can thrive under various environmental conditions. This variety helps farmers adapt to challenges like climate change, pests, and diseases. By having multiple species and varieties available, agricultural systems can be more resilient, reducing the risk of total crop failure due to specific threats.
• Evaluate the impact of modern agricultural practices on agro-biodiversity.
  • Modern agricultural practices often prioritize high-yielding crop varieties and monoculture systems, which can significantly reduce agro-biodiversity. This focus on a limited number of species can lead to the loss of traditional varieties and local breeds, diminishing genetic diversity. The reduction in agro-biodiversity makes food systems more vulnerable to pests and environmental changes, ultimately threatening long-term food security.
• Assess the role of policy and community initiatives in promoting agro-biodiversity conservation.
  • Policies aimed at promoting agro-biodiversity conservation can play a crucial role in protecting diverse agricultural practices. Community initiatives like seed saving programs and local farmer cooperatives encourage the cultivation of traditional crops and local breeds. These efforts help maintain genetic diversity within agricultural systems while also fostering community resilience by supporting sustainable farming practices. Together, policies and community actions can create a supportive environment for agro-biodiversity conservation.
