Biodiversity is critical for agriculture, providing essential ecosystem services and food production. However, modern agricultural practices threaten biodiversity through land-use change, pollution, and resource overuse, necessitating a shift in policies and collaborative efforts among stakeholders. Additionally, agriculture faces the dual challenge of feeding a growing population while minimizing environmental impact, highlighting the importance of traditional farmers' knowledge in sustaining biodiversity and food security.

- 3. Biodiversity Biodiversity is the foundation of agriculture. Agricultural biodiversity includes ecosystems, animals, plants and microorganisms related to food and agriculture. Today, most species of crops and domesticated livestock are the result of thousands of years of human intervention, such as selective breeding and other farm practices
- 4. Agriculture Biodiversity Agricultural biodiversity provides food and raw materials to produce goods. Moreover, every plant, animal and microorganism plays its part in the regulation of essential ecosystem services, such as water conservation, decomposition of waste and nutrient cycling, pollination, pest and disease control, climate regulation, erosion control and flood prevention, carbon sequestration and many more
- 5. Modern Agriculture Practices While modern agricultural practices have increased food production, contributing much to improving food security and reducing poverty, they have also been responsible for considerable damage to biodiversity, primarily through land- use conversion but also through overexploitation, intensification of agricultural production systems, excessive chemical and water use, nutrient loading, pollution and introduction of invasive alien species. Agriculture is part of the landscape and needs to be managed wisely and sustainably in this context.
- 6. Farmers Traditional Knowledge Farmers’ traditional knowledge is central to both sustaining biodiversity and ensuring global food security. Today this knowledge is being eroded, undermining the important contribution that farmers can make.
- 7. Agriculture Faces Challenges Agriculture faces considerable challenges of meeting the requirements of an ever growing population whilst simultaneously reducing its footprint on the earth’s resources and biodiversity. Technically these challenges can be met but this requires significant shifts in policies and approaches. Central to this is the need for more effective partnerships between farmers, consumers, governments and other stakeholders which build upon the contribution that biodiversity can make towards the achievement of sustainable agriculture.
- 8. Fast Facts In Close to a quarter of the world’s population (1.3 billion people) work in agriculture n Over 826 million people are chronically hungry and need 100–400 more calories per day n 32% of pre-school children worldwide are underweigh
- 9. Fast Facts Agriculture accounts for 44% of methane emissions and about 70% of nitrous oxide gases n Globally, agriculture accounts for about 70% of the water used by humans, and the sustainable limit of water withdrawal has already been reached or exceeded in many areas
- 10. Fast Facts Deforestation in the tropics and sub- tropics, driven in many places by agriculture, can lead to a reduction in regional rainfall— undermining sustainable water supplies for agriculture
- 11. Fast Facts 20% of the 6,500 breeds of domesticated animals face extinction n 20% of CO2 emissions in the 1990s originated from land use changes, much of this was through deforestation for agriculture n There are over 25,000 bee species, but populations are declining. One-third of the world’s crop production must be pollinated to produce seeds and fruits n Soil worldwide is being lost 13 to 18 times faster than it is being formed
