In heterogeneous landscapes where the variation of crops, hedges, trees and meadows is greater, wild pollinators and “beneficial” insects are more abundant and diversified. Not only do pollination and biological control increase, so does the crop yield.
How does increasing biodiversity help the farm?
Biodiversity is the basis of agriculture and our food systems. … Agricultural biodiversity also performs ecosystem services such as soil and water conservation, maintenance of soil fertility, conservation of biota and pollination of plants, all of which are essential for food production and for human survival.
How can biodiversity be used to improve food production?
Secondly, another use of biodiversity in food production is the use of natural predators to control pests. … Mixing crop species together, or even increasing the genetic diversity within a single crop species, can reduce damage by pests (Fig 3). Improving plant diversity on farmland can act as a natural pesticide.
How agricultural biodiversity increases crop production?
Biodiversity helps in regulating the functioning of ecosystems by improving the variety and level of biological processes that help in agricultural production. … In particular it increases resilience of agro-ecosystems and is as such a means for risk reduction and adaptation to climate change.
Why is biodiversity important to sustainability in farming?
Conservation and maintenance of biodiversity are important for four reasons. … Economics: Biodiversity provides us with great economic returns, for example the provision of food and fibre, medicines, control of pest organisms, building materials and crop pollination.
What is the best way to increase diversity in the farm?
Strategies for Enhancing Plant Diversity
- Diversify enterprises by including more species of crops and livestock.
- Use legume-based crop rotations and mixed pastures.
- Intercrop or strip-crop annual crops where feasible.
- Mix varieties of the same crop.
What are the benefits of biodiversity?
A healthy biodiversity offers many natural services
- Protection of water resources.
- Soils formation and protection.
- Nutrient storage and recycling.
- Pollution breakdown and absorption.
- Contribution to climate stability.
- Maintenance of ecosystems.
- Recovery from unpredictable events.
Why is biodiversity important for food supplies?
Biodiversity underpins all food production and strengthens agricultural resilience to shocks and stresses that can lead to crop failure. … “Less biodiversity means that plants and animals are more vulnerable to pests and diseases,” says José Graziano da Silva, Director-General of the UN FAO.
How does biodiversity affect the food chain?
Biodiversity provides “raw materials” for the food chain and seafood production, and also influences the capacity of ecosystems to perform these and other services. … Structural redundancy is evident in marine ecosystems, in that many species are interchangeable in the way they characterise assemblage composition.
What are two ways the farmer could increase biodiversity on his farm?
Excluding portions of land from production around the margins of fields will promote wildlife by increasing food and habitat opportunities and by limiting exposure to fertiliser and pesticide applications.
How can plants increase biodiversity?
Have fun adding to the biodiversity of your garden and enjoy nature’s bounty and diversity.
- Attract birds to your garden. …
- Add a butterfly garden. …
- Add a pollinator garden. …
- Add water to your garden. …
- Add a log, build a rock pile or preserve a snag. …
- Add a birdhouse, bat house or native pollinator house.
How can increasing biodiversity help in pest and disease management and soil health?
• Improves soil
High-quality soils encourage dense populations of micro organisms, enhance natural biological control of pathogens, slow turnover of nutrients, encourage communities of beneficial insects and improve soil aeration and drainage.
