Biodiversity makes production systems and livelihoods more resilient to shocks and stresses, including those caused by climate change. It is a key resource in efforts to increase food production while limiting negative impacts on the environment.
How does biodiversity help agriculture?
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 helped increase food production?
Plant existing cropland more frequently.
Planting and harvesting existing croplands more frequently, either by reducing fallow land or by increasing “double cropping” (planting two crops in a field in the same year), can boost food production without requiring new land.
Does biodiversity increase food security?
“Biodiversity is critical for safeguarding global food security, underpinning healthy and nutritious diets, improving rural livelihoods, and enhancing the resilience of people and communities.
What does biodiversity increase?
Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
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 is the role of biodiversity on food?
Biodiversity is the origin of all species of crops and domesticated livestock and the variety within them. … Maintenance of this biodiversity is essential for the sustainable production of food and other agricultural products and the benefits these provide to humanity, including food security, nutrition and livelihoods.
What does an increase in agricultural production mean?
Highlights: Since 1948, U.S. agricultural productivity has more than doubled, enabling farmers to feed more people with less land and labor. Agricultural output growth is attributed to the growth in total inputs used and in technology advancement, or total factor productivity (TFP).
What are the three options to increase food production?
The three options that have been used for increasing food production are (i) agro-chemical based agriculture (ii) organic agriculture; and (iii) genetically engineered crop-based agriculture.
How can we increase crop production?

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.
How does biodiversity affect ecosystem services?
Many key ecosystem services provided by biodiversity, such as nutrient cycling, carbon sequestration, pest regulation and pollination, sustain agricultural productivity. Promoting the healthy functioning of ecosystems ensures the resilience of agriculture as it intensifies to meet growing demands for food production.
Where does biodiversity increase?
Generally, there is an increase in biodiversity from the poles to the tropics. Thus localities at lower latitudes have more species than localities at higher latitudes. This is often referred to as the latitudinal gradient in species diversity.
Does biodiversity increase or decrease sustainability?
That is, biodiversity can increase overall ecosystem stability when biodiversity is low, and decrease it when biodiversity is high, or the opposite with a U-shaped relationship.
How does biodiversity increase stability of an ecosystem?
Increased alpha diversity (the number of species present) generally leads to greater stability, meaning an ecosystem that has a greater number of species is more likely to withstand a disturbance than an ecosystem of the same size with a lower number of species.
