why is genetic diversity important in agriculture?
440732
Genetic diversity is needed to safeguard potentially vital traits that could be used to combat an unexpected future pest or adapt to the needs of the world's food supply. Plant breeders utilize genetic diversity to create improved crop varieties with traits such as yield, pest resistance and environment stress.

Biodiversity is the variety of life in the world or in a particular habitat or ecosystem. Biodiversity is important because it provides us with Natural Resources (Food, Water, Wood, etc.) Natural Services (Pest Control, Air and Water Purification, etc.) and of course, Aesthetic Pleasure.

Agricultural biodiversity is essential to satisfy basic human needs for food and livelihood security. ... It contributes directly to food security, nutrition and well-being by providing a variety of plant and animals from domesticated and wild sources.

Food security: why is biodiversity important? Agriculture and biodiversity have often been regarded as separate concerns. ... The nutritional and livelihood benefits of diverse production systems are one way of achieving food security. Such systems are also more resilient to climate induced events or other shocks.

What is the difference between classically bred varieties and landraces? ... Land races were replaced with new varieties reducing crop plant genetic diversity. Population growth continued, and eventually outpaced increases in food production. Fertilizers and pesticides can cause environmental contamination.

Biodiversity is not only the sum of all ecosystems, species and genetic material. Rather, it represents the variability within and among them. ... while biological diversity is rather an attribute of life (the variety of bird species, the genetic variability of wheat around the world, forest types, etc.).

Crop diversification refers to the addition of new crops or cropping systems to agricultural production on a particular farm taking into account the different returns from value-added crops with complementary marketing opportunities.

Biodiversity is essential for sustainable development and human well-being. It underpins the provision of food, fibre and water; it mitigates and provides resilience to climate change; it supports human health, and provides jobs in agriculture, fisheries, forestry and many other sectors.

Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms.

The prevalence of GMOs in major field crops threatens the genetic diversity of our food supply. Genetic diversity helps individual species adjust to new conditions, diseases and pests, and can aid ecosystems in adapting to a changing environment or severe conditions like drought or floods.

Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms. It occurs within a species as well as between species.

Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele.

Genetic diversity is important because it helps maintain the health of a population, by including alleles that may be valuable in resisting diseases, pests and other stresses. ... If the environment changes, a population that has a higher variability of alleles will be better able to evolve to adapt to the new environment.

Biotechnology holds tremendous possibilities for the developing world. The use of high-yielding, disease- and pest-resistant crops will have a direct bearing on improved food security, poverty alleviation and environmental conservation. GM crops will hopefully produce more yield on less land.

Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species. It is distinguished from genetic variability, which describes the tendency of genetic characteristics to vary. Genetic diversity serves as a way for populations to adapt to changing environments.

Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. ... Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.

The greater the genetic diversity within a species, the greater that species' chances of long-term survival. This is because negative traits (such as inherited diseases) become widespread within a population when that population is left to reproduce only with its own members.
