Why does biodiversity matter for agriculture?

Our study demonstrates the benefits of biodiversification for agriculture. In essence, agricultural fields with greater biodiversity are better protected from harmful insect pests, promote wild pollination, and produce higher yields.

What is biodiversity and why is it important?

It contributes directly to food security, nutrition and well-being by providing a variety of plant and animals from domesticated and wild sources. Biodiversity can also serve as a safety-net to vulnerable households during times of crisis, provide income opportunity to the rural poor and sustain productive agricultural ecosystems.

How can we protect wildlife and biodiversity through sustainable farming?

Farming approaches can be tailored to benefit wildlife and biodiversity, which in turn can increase ecosystem stability in the face of environmental change, without reducing the potential for agricultural yield.

What is the relationship between biodiversity and nutrition?

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

What is biodiversity in agriculture?

Biodiversity in agriculture includes all components involved in promoting diversity of food products and agriculture. It includes genetic resources of crops, wild plants harvested and managed for foods, trees on farms, rangeland species, pastures, and lastly medicinal plants. SEE ALSO 21 Examples of Renewable and Non-renewable Energy Resources.

How does biodiversity help humans?

Agricultural biodiversity helps to provide humans with foods, raw materials for goods like cotton, wool, wood, fuel, and the roots of wild plants are used for medicines. They also help to become a source of biofuel. The process of agricultural biodiversity also helps to provide valuable services to ecosystems.

What is Biodiversity?

Biodiversity is the scale on which we measure the variety in ecosystems, genetic, and species levels. It helps us to determine the variability on Earth. This variability is important, as it allows us to keep ecosystems, environment and their relationship in check.

What happens if farmers consider biodiversity into the equation of agriculture?

If farmers choose to consider biodiversity into the equation of agriculture they may go onto make crops with better yields, as well as save the environment from taking damage.

Why is conservation tillage important?

This practice allows crop residue to remain on the surface, reducing the opportunity for soil erosion. The practice of conservation tillage has started to increase on farms.

What is cover crop?

Cover crops are planted by farmers in between the cash crop harvests. The goal is to plant crops that recycle nutrients back into the soil. Crops like radishes or rye; assist in conserving soil, preventing soil erosion, and replenish lost nutrients and provides a number of benefits to the soil for future crops.

How does biodiversity affect food?

Biodiversity interacts with food and nutrition to deal with several issues. It helps to provide food security, nutrition, and well-being for a variety of animals and plants (both domesticated and wild).

How can we help wildlife?

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. The amount of land which can be spared will depend on field and farm size, but even a one metre strip between hedge and crop has been shown to benefit wildlife. Alternatively, a strip of habitat can be created across the middle of a field, which will provide habitat for small mammals and invertebrates (usually a double ploughed ridge sown with native tussock grasses). These are often referred to as ‘beetle banks’ and should be approximately 2-3 metres wide for best effect. Tree and hedgerow planting, to create woody vegetation patches, will also benefit wildlife and can have additional beneficial effects from stock management and ecosystem service perspectives.

How does increasing plant diversity affect grassland?

Other studies have demonstrated increased yield in grassland as a result of increasing plant diversity by sowing species rich seed mixtures. In an experiment considering gradients of plant species richness and management intensity, higher diversity was shown to be more effective in increasing productivity than higher management intensity and low-input high-diversity fields had similar productivity to high-input low-diversity management regimes. Whilst overall costs associated with restoration would need further consideration, and some thought should also be given to field and soil preparation as soil nutrient status is likely to dictate the success of sowing species rich mixtures, this demonstrates the potential for increasing habitat availability whilst reducing environmental impact and cost of production to the farmer, by reducing fertiliser input requirements.

Why is biodiversity important?

Biodiversity is important for the regulation of ecosystem processes and delivery of ecosystem services. Farming approaches can be tailored to benefit wildlife and biodiversity, which in turn can increase ecosystem stability in the face of environmental change, without reducing the potential for agricultural yield.

How does land use affect biodiversity?

Land use and management intensity are key factors influencing biodiversity in the agro-eco system, as this reduces food and habitat availability for wildlife. As an example, management approaches such as fertiliser usage, grazing intensity and mowing frequency in grassland systems, have been shown to result in biodiversity loss through …

How does low nutrient input farming affect biodiversity?

Low nutrient input farming approaches, such as organic farming methods, can reduce biodiversity loss and these farms are typically richer in wildlife than conventionally managed …

What are the benefits of wildlife friendly farming?

Wildlife-friendly farming strategies can support wildlife that is considered beneficial in an agricultural context, such as those which engage in pollination or as natural enemies of crop pests. This in turn may have positive influences on agricultural production.

What is the most important environment in the UK?

This has the potential to increase the conversion of land which has not been previously used for agriculture, or to intensify agricultural activities on land already used for food production. Farmland habitat, referred to as the agroecosystem, is perhaps the most important environment in the UK in terms of wildlife and biodiversity, …

Why is genetic variation important?

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 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.

Why is biodiversity important?

DNA is intrinsic to all living things, and that genetic code evolves over time. Different genes correspond to different traits in the organism. We can see many of these traits with our own eyes, but others are less obvious, like genes for stress and disease resistance. This genetic diversity is vital to ensuring that species can survive the ever-changing conditions their environment presents.

What is biodiversity and agriculture?

Biodiversity and Agriculture. Biodiversity is the immense variety we see in all life on earth. As living things adapt to their environment and evolve over time, more and more variation emerges. Scientists estimate that at least 8.7 million unique species of animals, plants, fungi, and other organisms exist on Earth, …

Why do crops depend on genetic diversity?

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.

What is the purpose of extensification?

Extensification. Bringing more wild lands into agriculture to produce more food. Agricultural extensification isn’t new. In the United States, grassland ecosystems like the tallgrass prairie once covered nearly 170 million acres, and supported nearly as many plant and animal species as tropical rainforests.

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 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.

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.

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.

What is evenness in insect populations?

We also looked at a further measure – called evenness (or the complementary term, dominance) – that may have relevance to the makeup of insect populations. In real-world ecosystems, a handful of highly abundant, dominant species live alongside a higher number of rarer species. As landscapes became less diverse, insect assemblages become impoverished and dominated by a few abundant species. These species, however, supply ecosystem services less efficiently than in more diverse landscapes where relatively rare species provide a valuable contribution in addition to dominant ones.

Who is Ingolf Steffan-Dewenter?

Ingolf Steffan-Dewenter is Professor at Department of Animal Ecology and Tropical Biology, Biocenter, University of Würzburg, Würzburg, Germany.

What is biodiversity in biology?

Biodiversity refers to variability among the living organisms which are existing and interacting in various terrestrial, marine system during the specific timeframe within an ecosystem (Altieri, 999; UN, 2015; Kumar, 2015). Generally, biodiversity consists of three major components such as species diversity, genetic diversity, and ecosystem diversity which have a significant role in the entire ecosystem (Rawat & Agarwal, 2015; Kumar, 2015). Furthermore, biodiversity is different forms of life on earth which consist of different species organisms. It is promoting the aesthetic value of the natural environment and support to life system by providing food, fodder, fuel, medicine, and timber etc. but unfortunately human activities cause of global warming, catastrophe, soil degradation, and habitat loss which is an alarming threat to species and ecosystem diversity (Rawat & Agarwal, 2015).

Why is biodiversity important?

Conservation of biodiversity plays important role in the functioning and delivering ecosystem services. Agroecosystems make agricultural crop production more sustainable and economically viable by maintaining high biodiversity. Agricultural biodiversity protects to pollination of crops, biological crops, maintenance of proper structure and soil fertility against nutrient cycling, soil erosion, and control of water flow and distribution (Feledyn-Szewczyk et al., 2016). Biodiversity in agricultural sector can be recognised on two levels: first level is related to species and cultivars diversity,

What is the meaning of biodiversity?

MEANING OF BIODIVERSITY Biodiversity may be defined as the variability among different living organisms from all sources and ecological complexes of which they are parts and includes diversity within species or between species and of eco-system. In the context of environmental science, the study of all living organisms including human beings, and other living

What is the purpose of fertilizer?

Introduction Aim: To compare the effectiveness of compost and earthworms on the germination and yield of a spinach crop. Motivation: Fertilisers are mixture of chemicals that add nutrients to the soil to establish better yielding crops (Berger, 2013). Though these products have proved to provide many beneficial aspects to the agricultural sector, they have many negative environmental consequences. Fertilisers contain many substances, including mostly potassium, phosphorus, sulphur, calcium, magnesium and nitrogen. These substances, when they accumulate in the soil, can have harmful side effects on the environment and subsequently on the productivity of crops (Vimpany and Lines-Kelly, 2004).

How do plants affect the environment?

In nature, plants grow next to each other forming the different societies of the plant kingdom. Nature, in turn, affects the growth of these plants by applying different environmental factors that could limit the agricultural productivity. Duration, severity and rate of imposed stress are the factors underlying the plant response to stress (Munné-Bosch and Alegre, 2004; Omezzine et al., 2014).

What are the resources of animals?

Animal genetic resources include domesticated animals, wild animals hunted for food, wild and farmed fish and other aquatic organisms, insect pollinators and microbial and fungal genetic resources. Agricultural biodiversity provides humans with food, raw materials for goods such as: cotton and wool for clothing; wood for shelter and fuel;

How does genetic diversity affect agriculture?

In addition, genetic diversity of agricultural biodiversity provides species with the ability to adapt to changing environments and to evolve by increasing their adaptation to frost, high temperature, drought and waterlogging as well as their resistances to diseases, insects and parasites.

What is the basis of agriculture?

Biodiversity is the basis of agriculture and our food systems. It has enabled farming systems to evolve since the origin of agriculture about 10,000 years ago. Our civilization evolved when human beings started domesticating plants and animals. Agricultural biodiversity includes all components of biological diversity of relevance to food …

What is agricultural biodiversity?

Agricultural biodiversity includes all components of biological diversity of relevance to food and agriculture. It includes plants’ genetic resources: crops, wild plants harvested and managed for food, trees on farms, pastures and rangeland species, medicinal plants and ornamental plants of aesthetic value.

Why is biodiversity important in agriculture?

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

What is the role of biodiversity in agriculture?

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.

Why are coping mechanisms important?

Coping mechanisms based on indigenous plants are particularly important for the most vulnerable people who have little access to formal employment, land or market opportunities. Wild indigenous plants provide alternate sources of food when harvests fail. Finally, genetic diversity of plant’s genetic sources is the basis of crop improvement.
