Why is it so hard to meet the demand for accelerated agricultural productivity?

The reasons for this have to do with ecological factors. Global climate change is destabilizing many of the natural processes that make modern agriculture possible.

How do cattle damage soil?

Cattle and other large grazing animals can even damage soil by trampling on it. Bare, compacted land can bring about soil erosion and destruction of topsoil quality due to the runoff of nutrients. These and other impacts can destabilize a variety of fragile ecosystems and wildlife habitats. Chemical Fertilizer.

What is the effect of nitrogen on soil?

In addition, fertilizer application in soil leads to the formation and release of nitrous oxide, one of the most harmful greenhouse gases.

How does irrigation affect water?

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.

How does agriculture affect the environment?

While negative impacts are serious, and can include pollution and degradation of soil, water, and air, agriculture can also positively impact the environment, for instance by trapping greenhouse gases within crops and soils, or mitigating flood risks through the adoption …

What is the challenge of agriculture?

A key challenge for the agriculture sector is to feed an increasing global population, while at the same time reducing the environmental impact and preserving natural resources for future generations. Agriculture can have significant impacts on the environment.

What are some of the best practices farmers have made?

Farmers have also made good progress in adopting more environmentally beneficial practices, such as conservation tillage, improved manure storage, or soil nutrient testing. Notwithstanding these improvements, there is still more to do, with an important role for policymakers.

Is nitrogen balance increasing in OECD countries?

Nitrogen balances are increasing in several OECD countries, farmland bird populations continue to decline and the sector’s contribution to water use and contamination is still high relative to other uses.

Is agriculture a part of the OECD?

In recent years, there have been some encouraging signs that the agriculture sector of OECD countries is capable of meeting its environmental challenges. In particular, farmers in many OECD countries have made improvements in the use and management of nutrients, pesticides, energy and water, using less of these inputs per unit of land.

How does agriculture affect the environment?

The environmental impact of agriculture involves impacts on a variety of different factors: the soil, to water, the air, animal and soil variety, people, plants, and the food itself. Agriculture contributes to a number larger of environmental issues that cause environmental degradation including: climate change, deforestation, biodiversity loss, …

What are the bad practices in agriculture?

Bad management practices include poorly managed animal feeding operations, overgrazing, plowing, fertilizer, and improper, excessive, or badly timed use of pesticides. Pollutants from agriculture greatly affect water quality and can be found in lakes, rivers, wetlands, estuaries, and groundwater.

Why do pesticides and plasticulture cause death?

The runoff from pesticides and chemicals in the plastic can cause serious deformations and death in shellfish as the runoff carries the chemicals towards the oceans.

How do pesticides affect other species?

Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields. Runoff can carry pesticides into aquatic environments while wind can carry them to other fields, grazing areas, human settlements and undeveloped areas, potentially affecting other species. Other problems emerge from poor production, transport and storage practices. Over time, repeated application increases pest resistance, while its effects on other species can facilitate the pest’s resurgence.

What are the causes of soil degradation?

Common attributes of soil degradation can be salting, waterlogging, compaction, pesticide contamination, a decline in soil structure quality, loss of fertility, changes in soil acidity, alkalinity, salinity, and erosion. Soil erosion is the wearing away of topsoil by water, wind, or farming activities. Topsoil is very fertile, which makes it valuable to farmers growing crops. Soil degradation also has a huge impact on biological degradation, which affects the microbial community of the soil and can alter nutrient cycling, pest and disease control, and chemical transformation properties of the soil.

What is sustainable agriculture?

Sustainable agriculture is the idea that agriculture should occur in a way such that we can continue to produce what is necessary without infringing on the ability for future generations to do the same.

What are the main causes of extinction?

The 2019 IPBES Global Assessment Report on Biodiversity and Ecosystem Services found that industrial agriculture and overfishing are the primary drivers of the extinction, with the meat and dairy industries having a substantial impact.

How does artificial farming affect the environment?

Besides the environment, it also affects the health of humans and other animals as they are directly dependent on it for food. So, agriculture is one of the precious means of work and has to be done with ethics.

How does food contamination affect the body?

Once, they get into the body; they alter the hormonal secretions and nervous system . Since these are vital body systems; the health of the individual is affected over time.

What are the three types of pollution?

6. Destruction of natural species. Pollution: Agriculture leads to three type of pollution like. Air pollution. Soil pollution. Water pollution. All these three forms of pollution are again due to a single cause. That is the heavy use of chemical manures and pesticides.

Why is fertilizer discontinued?

But, due to the recognition of its effects on the soil and environment , this has been discontinued.

Why are seed companies important?

The seed companies introduce the techniques of biotechnology to enhance disease resistance, drought resistance etc. In doing so, the farmers become dependent on these seeds. The natural seeds are extinct in many places. These seeds produced by the company may give rise to high crop yield.

Why is the pH of soil changing?

Bacteria in the soil tend to decay the waste and enhance soil fertility. But when the pH is changed, they are unable to survive; this leads to the destruction of environmental diversity and balance.

How does deforestation affect groundwater?

The decrease in groundwater: Water for irrigation is mostly supplied by rains and also rivers. Due to deforestation, the rains are minimal. Due to this, farmers rely on tube well or bore wells to irrigate their crops using groundwater. When widely used, the groundwater levels reduce.

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.

What is hydroponics farming?

Hydroponics, for those that don’t know, is a form of agriculture that does not use soil. Rather than growing in soil, crops are grown in some nutrient-lacking substrate with nutrients delivered through the water. Typically, it is done in gravel, sand, or just water only, and is commonly done indoors. This allows for high degrees of control over growing conditions, including light levels and wavelengths, temperatures, nutrient concentrations, and more. Linked below is a video from the BBC Earth Lab that elaborates more on what hydroponics really is and how it works.

Is hydroponics better than conventional agriculture?

Hydroponics as it stands currently is by no means a solution to the biodiversity crisis resulting from conventional agriculture, but it can be. It is better than conventional agriculture in every way except energy usage and the resulting costs. If this issue was resolved, hydroponic agriculture would be entirely viable and beneficial to employ over conventional methods, greatly reducing the environmental damage it causes. Through research, hydroponic processes and technologies could be refined to cut energy usage, making it cheaper and more accessible for farmers around the globe. If we really care about the harm that conventional agriculture does, governments need to fund or otherwise incentivise research on hydroponics to facilitate change. Our current methods of agriculture cannot be sustained forever, and if we don’t change soon, there are bound to be consequences. Change starts with the individual, so please, at the very least, understand this: conventional agriculture is problem, and the biodiversity crisis to which it contributes will cause a mass extinction if nothing is done. Remember this the next time you hear about another species from the Amazon going extinct from habitat loss.

How does urban agriculture help the environment?

Urban agriculture on a small scale can help to localize food production, reducing the overall environmental footprint of our modern food systems. Benefits include lower greenhouse gas emissions, minimal transportation requirements, and reduced energy use for food production.

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.

How do plants and trees help the aquifer?

Plants and trees in agricultural systems help to retain and add water to underground aquifers. This process is most effective when the crops being grown are perennials that continue to grow every year and have deep, well-established root systems.

What are some examples of perennial plants grown on farms?

Examples of some perennial plants grown on farms are alfalfa, fruit trees, olive trees, berries and grapes. Together, they act as an important buffer in the landscape, preventing flooding, reducing water pollution from agricultural runoff and preventing erosion, while providing us with nutritious food at the same time.
