What is the relationship between biodiversity and food security?

“Less biodiversity means that plants and animals are more vulnerable to pests and diseases. Compounded by our reliance on fewer and fewer species to feed ourselves, the increasing loss of biodiversity for food and agriculture puts food security and nutrition at risk.”

How biodiversity and food security are related?

Although biodiversity underpins much of modern agriculture, the development of contemporary production systems has resulted in extensive land conversion and concomitant biodiversity loss. … The nutritional and livelihood benefits of diverse production systems are one way of achieving food security.

How is food related to biodiversity?

Biodiversity for food and agriculture is all the plants and animals – wild and domesticated – that provide food, feed, fuel and fibre. It is also the myriad of organisms that support food production through ecosystem services – called “associated biodiversity”.

Why biodiversity is important for food?

Biodiversity is essential to food and agriculture

It supplies many vital ecosystem services, such as creating and maintaining healthy soils, pollinating plants, controlling pests and providing habitat for wildlife, including for fish and other species that are vital to food production and agricultural livelihoods.

What is the relationship between biodiversity and a healthy environment?

Biodiversity supports human and societal needs, including food and nutrition security, energy, development of medicines and pharmaceuticals and freshwater, which together underpin good health. It also supports economic opportunities, and leisure activities that contribute to overall wellbeing.

What are the issues in biodiversity and food security & food safety?

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.

Why is biodiversity important to maintaining food webs and food chains?
