How does agriculture help the ecosystem?

Agriculture plays a major role in protecting ecosystem services, and in turn can reap great benefits from services that are functioning properly.


What are the functions of ecosystem services?

These functions, known as ecosystem services, include all the jobs performed by the components of an ecosystem, coming from biotic components like plants and insects, to abiotic components, such as the soil and wind.


What is an agricultural ecosystem?

The agricultural ecosystem. An ecosystem is defined as all the organisms (animals, plants, microbes) in a certain habitat, plus also the environment that they live in (such as the soil, a pond, or a mountainside).


How are natural ecosystems different from agricultural ecosystems?

In contrast, an agricultural ecosystem (such as a corn field or an orchard) is relatively artificial, being modified and controlled by humans. It contains fewer species and thus is simpler in its functioning.


What is an invasion of a crop pest?

An invasion of a crop pest such as aphids or caterpillars will likely spread and ruin the crop rather than being controlled by predatory insects (ladybugs, wasps) or birds, as when the farmer leaves areas of natural ecosystem near his fields.


Why are plants healthy?

Plants that grow in good, rich soil are likely to be healthy. Healthy plants are able to resist or repel most pests and diseases, by means of various processes analogous to the way our body’s immune system protects us from diseases. And healthy plants also produce more nutritious food for animals and humans.


How does crop rotation benefit the farm?

Crop rotations also provide similar benefits. Diversify the farm by raising a variety of crops and animals. Not only can diversity protect against bad weather and volatile markets, but a variety of species is a closer approximation of a natural ecosystem than is a monoculture of one or two crops and no animals.


What is the function of ecosystems?

Thus a natural ecosystem is sustainable, able to continue indefinitely. The variety of species in nature is often called “biological diversity,” or “biodiversity.”. Natural ecosystems also perform a number of functions that benefit humans, called ecosystem services . These may include moderating the local weather …

Irrigation causes increases in water evaporation, impacting both surface air temperature and pressure as well as atmospheric moisture conditions . Recent studies have confirmed that cropland irrigation can influence rainfall patterns not only over the irrigated area but even thousands of miles away.


What is irrigation related to?

Irrigation has also been connected to the erosion of coastlines and other kinds of long-term ecological and habitat destruction. A huge amount of agricultural territory is used primarily as pasture for cattle and other livestock.


What causes algae blooms in China?

Nutrient pollution is a causal factor in toxic algae blooms affecting lakes in China, the United States, and elsewhere. As excessive amounts of organic matter decompose in aquatic environments, they can bring about oxygen depletion and create “dead zones” within bodies of water, where nothing can survive.


What are the consequences of irrigation?

One of the most obvious consequences is the depletion of aquifers, river systems, and downstream ground water. However, there are a number of other negative effects related to irrigation.


What will happen to the world population as the population continues to skyrocket?

What are some examples of agricultural systems?

For example, open meadow habitats are important for species like waterfowl, amphibians and for pollinators. Some species even increase in number due to agricultural activities.


How does rotational grazing affect biodiversity?

Through grazing for a limited time period in one area, biodiversity of native plants increases because grasses have time to regrow equally without one species taking over and becoming invasive.


Why do grasslands exist?

Grasslands provide habitat to a great number of animals and native plants. These areas have been almost entirely wiped out in other countries of Europe due to modern development or intensive agriculture. In Romania, however, they still exist because of the traditional (low-impact) way of farming and seasonal grazing of livestock by shepherds.


Why is maintaining land important?

Maintaining land for agricultural use can also prevent that land from being developed and urbanized, in areas where native species have difficulty finding original habitat. The United States Department of Agriculture Farm Service Agency (FSA) created seven voluntary land conservation programs for this purpose.

Whether the outcome of this change delivers negative or positive consequences depends largely on our approach. You may think it sounds counter-intuitive, but sustainable management …


What are the environmental concerns of agriculture?

One of the primary environmental concerns with modern agriculture has to do with the chemicals we put on crops and what happens when those crops end up in the watershed. Pesticides and other chemicals are often used to produce more crops, and these pesticides don’t just fall on the crops and stay there: they are transported via wind and water …


What happens when we clear land for agriculture?

Forests, grasslands, and other ecosystems are converted for farmland. When we clear land for agriculture, we often lose some soil.


What is the result of eutrophication?

The result may be eutrophication, an excessive amount of nutrients in a body of water resulting in a substantial growth of plants, such as algae, and a lack of oxygen in the water because of this increase in plants. There is a finite amount of land on the planet, and agricultural practices take up a lot of land.


Where do fertilizers end up?

Fertilizers, while a nutrient for some plants, end up in streams and lakes in amounts higher than would occur naturally.


Does soil degrade over time?

Thus, the soil degrades over time. If we’re in areas with heavy rainfall, replacing forests with cropland often results in an increase in flooding. Another problem has to do with the amount of water some crops require. Agriculture is the industry with the largest water consumption.


Abstract

Human expansion throughout the world caused that agriculture is a dominant form of land management globally. Human influence on the land is accelerating because of rapid population growth and increasing food requirements.


1. Introduction

Land cover and land‐use patterns on Earth reflect the interaction of human activities and the natural environment [ 1 ]. Human population growth together with competitive land use causes land scarcity, conversion of wild lands to agriculture and other uses.


3. Results and discussion

With the growing world population the requirements are grown to cover the food demand. Human expansion throughout the world caused that agriculture is a dominant form of land management globally, and agricultural ecosystems cover nearly 40% of the terrestrial surface of the Earth.


4. Conclusion

Agriculture is a dominant form of land management globally. Rapid population growth as primary driving force connected with increasing food requirements generate great pressure on future land use, environment, natural resources, and ecosystem services.
