What is Agricultural Biodiversity?
- Plant genetic resources, including crops, wild plants harvested and managed for food, trees on farms, pasture and rangeland species,
- Animal genetic resources, including domesticated animals, wild animals hunted for food, wild and farmed fish and other aquatic organisms,
- Microbial and fungal genetic resources.
What has agricultural biodiversity ever done for US?
First, agricultural biodiversity provides us with food. Agricultural biodiversity gives us an enormous variety of food, not just countless tonnes of the same food.
What does agricultural biodiversity mean?
Agricultural biodiversity is a broad term that includes all components of biological diversity of relevance to food and agriculture, and all components of biological diversity that constitute the agricultural ecosystems, also named agro-ecosystems: the variety and variability of animals, plants and micro-organisms, at the genetic, species and ecosystem levels, which are necessary to sustain …
How does biodiversity affect agriculture?
With bees responsible for pollinating more than 70 percent of food crops around the world, caring for bees and their wellbeing is an important part of the global food chain.

What is Bioversity International?
Bioversity International works with partners around the world including a wide range of funders and research partners who share our vision and mission to deliver scientific evidence, management practices and policy options to use and safeguard agricultural and tree biodiversity to attain sustainable global food and nutrition security.
Why is conserving plant genetic resources in situ good?
Conserving plant genetic resources in situ so they can evolve with changing conditions is often said to be a good thing, yet with little evidence. A new study marshalls the evidence and raise important questions.
How much does a crop yield increase in Uganda?
Farmers in Uganda who grow varietal mixtures of crops perceive a yield increase of up to 28%. The results are boosting farmers’ motivations to use agricultural biodiversity for more resilient production systems.
Can bananas be integrated into African diets?
Bioversity International and partners are investigating how vitamin A-rich bananas from South Asia and the Pacific can be integrated into Eastern African diets to tack le one of the biggest health problems in the region .
Why is biodiversity important?
By providing important ecosystem services, like pest control and nutrient cycling, biodiversity reduces the need for costly and harmful external inputs. Having a greater diversity of genes, species and ecosystems makes production systems and livelihoods more resilient to shocks and stresses and often leads to more stable …
How does biodiversity affect food?
Links between biodiversity and food systems 1 By providing important ecosystem services, like pest control and nutrient cycling, biodiversity reduces the need for costly and harmful external inputs. 2 Having a greater diversity of genes, species and ecosystems makes production systems and livelihoods more resilient to shocks and stresses and often leads to more stable and efficient ecosystem service provision. This is especially important to consider in the context of climate change.
What is agricultural biodiversity?
Agricultural biodiversity is a broad term that includes all components of biological diversity of relevance to food and agriculture, and all components of biological diversity that constitute the agro-ecosystem.
Why is biodiversity important in agriculture?
Why is Agricultural Biodiversity Important? Agricultural biodiversity provides humans with food and raw materials for goods – such as cotton for clothing, wood for shelter and fuel, plants and roots for medicines – and with incomes and livelihoods, including those derived from subsistence farming.
What are the functions of biodiversity?
Agricultural biodiversity also performs ecosystem services such as soil and water conservation, maintenance of soil fertility and biota, and pollination, all of which are essential to human survival.
What is biodiversity and agriculture?
Biodiversity and Agriculture. Biodiversity is the immense variety we see in all life on earth. As living things adapt to their environment and evolve over time, more and more variation emerges. Scientists estimate that at least 8.7 million unique species of animals, plants, fungi, and other organisms exist on Earth, …
How does sustainable agriculture help biodiversity?
Sustainable agriculture embraces biodiversity by minimizing its impact on wild ecosystems and incorporating numerous plant and animal varieties into complex, on-farm ecosystems.
What are the innovations that helped farmers produce more food per acre?
Widespread adoption of steel plows, hybrid seeds, GMOs, chemical fertilizers and pesticides helped farmers produce more food per acre than ever before. More recently, the adoption of genetically modified seeds helped to increase yields even further. This productivity comes at a great cost, however. Wide fields of a single crop (called monocultures) provide simplicity for farmers and a steady supply of feed to factory farms, but they are biodiversity deserts. Maintaining monocultures requires intense chemical inputs that reduce the abundance of wild species both on and off the farm.
How do plants help the ecosystem?
Plants provide food and habitat to beneficial insects and birds that pollinate them and manage pests. Livestock can recycle leftover parts of crops and provide natural fertilizer to fields and pasture through manure. Agroecosystems depend on diversity to stay in balance, and industrial agriculture disturbs this.
How does monocropping destroy biodiversity?
Industrial agriculture’s impacts are not limited to habitat destruction through its expanding footprint: its reliance on heavy chemicals to create giant stands of single crops has serious consequences for plant, animal and microorganism biodiversity.
What is the most serious threat to biodiversity?
22 Climate change is one of the most serious threats to biodiversity, and affects even remote areas scarcely touched by humans.
What are the three things that plants, animals, and soil depend on?
The plants, soil, and animals all depend on one another for nutrients and habitat . In a functional agro-ecosystem, healthy soil microbes provide nutrients to plants, the root systems of which hold the soil in place. Plants provide food and habitat to beneficial insects and birds that pollinate them and manage pests.
