Why is biodiversity important in agriculture?

Long ago, humans harnessed and steered genetic diversity by domesticating edible plants and animals. Even without understanding genetics, the earliest farmers did this simply by choosing to raise plants that produced large, edible seeds. As these domesticated plants spread across the world, they evolved their own variations. Like their wild counterparts, crops also depend on genetic diversity for traits that help them resist disease and stay productive under stress. Genetic variation within crops also brings us the huge variety of foods we enjoy. Biodiversity within livestock is important for the same reasons, and there are thousands of heritage breeds of pigs, cattle, poultry and other animals that are beautiful, unique and specially adapted to their environments.


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.


How does biodiversity help the farm?

Maintaining biodiversity in the wild and in crops has benefits on the farm. Even though they are managed by humans, farms are still ecosystems. 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. 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 extensification affect biodiversity?

One of the most dramatic examples of biodiversity loss through extensification is the ongoing destruction of the tropical rainforest. Rainforests are hotspots of biodiversity, with the Amazon alone containing nearly 25 percent of all living terrestrial species. 8 80 percent of deforestation worldwide is attributed to the expanding footprint of agriculture. 9 While “slash and burn” agriculture — where farmers cut and burn small areas of forest, and farm them for a few seasons before moving on to another plot — is often blamed for this deforestation, these approaches actually do less harm than the industrially scaled agriculture, which is permanently replacing forest. Growing crops like soy and oil palms or raising cattle offers farmers more income than preserving forest, which drives the permanent deforestation of over 100,000 square miles a year, an area about the size of the UK. 1011


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.

What is the relationship between soil, plants, bacteria and other life?

The relationship between soil, plants, bacteria and other life is also referred to as the nitrogen cycle. As an example, consider all the species of animals and organisms involved in a simple field used in agriculture. As summarized from Vandana Shiva, Stolen Harvest (South End Press, 2000), pp 61–62:


What do bacteria feed on?

Bacteria feed on the cellulose fibers of straw that farmers return to the soil. Amoebas feed on bacteria making lignite fibers available for uptake by plants. Algae provide organic matter and serve as natural nitrogen fixers. Rodents that bore under the fields aerate the soil and improve its water-holding capacity.

Why is biodiversity important in agriculture?

Biodiversity in our agricultural land therefore is very important – and here are twelve reasons why. 1. The origin of all species. Biodiversity is the basis of agriculture. It has enabled farming systems to evolve ever since agriculture was first developed some 10,000 years ago. Biodiversity is the origin of all species …


How does agriculture affect biodiversity?

Agricultural land is often seen as having only one purpose: that of producing the highest yield of crop or also produce to generate revenue for the farmer or land owner. With our agriculture occupying almost half of the Earth’s land mass [1], it is clear that agriculture can have a critical impact on biodiversity.


How does biodiversity affect soil?

Soil health. Beyond pollination, agricultural biodiversity minimises soil erosion. This is critical as, worldwide, soil is being lost at a rate 13 to 80 times faster than it is being formed. It takes about 500 years to form 25 mm of soil under agricultural conditions, and about 1000 years to form the same amount in forest habitats.

Why is biodiversification important for agriculture?

In essence, agricultural fields with greater biodiversity are better protected from harmful insect pests, promote wild pollination, and produce higher yields.


Why is biodiversity important?

In summary, our paper shows that biodiversity is essential to ensure the provision of ecosystem services and maintain high and stable crop yields. For example, a farmer can depend less on pesticides to get rid of harmful insects if natural biological control is increased through higher agricultural biodiversity. With ongoing global change, the value of farmland biodiversity ensuring greater resilience against environmental disturbances will become even more important.


How does landscape simplification affect biodiversity?

The ongoing conversion of natural or seminatural land for agriculture and the fusing to larger crop fields – a process called landscape simplification – are threating agricultural biodiversity by killing off insects’ food and resources. With declines of insects, the ecosystems services the insects provided might wane as well. Yet, it remains unclear how these changes affect the number and mix of these species and ultimately how agricultural production might change as a result.


What are the main services of nature?

Nature is a vital service provider for agriculture in many ways. Fruit trees and other pollinator-dependent crops are pollinated by wild insects like bumblebees, solitary bees, or flies. Other insects like predatory ladybugs or ground beetles eat pests that would otherwise damage or even destroy crops. All these organisms play a key role in agroecosystems providing multiple ecosystem functions critical to food production.
