What are the environmental impacts of Agriculture?
Agriculture can have significant impacts on 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 of certain farming practices.

Does environmental science include agriculture?
Environmental science is the study of the interactions between physical, chemical and biological components of the Earth’s natural environment. These components include energy, agriculture, water and air.
What is environmental agriculture science?
Sustainable agriculture uses methods to produce food that don’t damage the environment or rely on toxic chemicals. Farmers and scientists have developed these methods because they produce food in ways that keep ecosystems and farmland healthy enough to continue to produce food into the future.
What is the connection between science and agriculture?
agricultural sciences, sciences dealing with food and fibre production and processing. They include the technologies of soil cultivation, crop cultivation and harvesting, animal production, and the processing of plant and animal products for human consumption and use. Food is the most basic human need.
Why do you study Environmental Science in the Department of agriculture?
The Environmental Science in Agricultural Systems major provides an educational foundation to prepare students for diversified careers focused on environmental issues related to agronomic and horticultural production.

What is agriculture and environmental science?
Studying in this field you will gain knowledge about global, regional and local issues from food production and farming, to food security and maintaining a safe and balanced natural environment.
What are my course options?
VET courses offer practical programs, which will help you to become job-ready. They also provide a pathway to further undergraduate study. In VET courses you can learn skills in animal handling, farm management, landscaping, aquaculture and soil testing.
What are the practices of modern agriculture?
In the case of crop plants, they include: selective breeding, tillage, the use of fertilizer and pesticides, irrigation, and reaping. Each practice helps to increase the yield of biomass that can be harvested for food or other uses.
How big should a pig stall be?
Breeding sows > 340 kg kept in an individual stall should have a space at least 80 cm wide and 210 cm long (1.5 m 2 ). Smaller animals may be provided with less width.
What are some examples of trees that are grown in plantations?
Some species of trees, such as pines (Pinus species), poplars (Populus spp.), Douglas-fir (Pseudotsuga menziesii), and spruces (Picea spp.), are grown in plantations (called agroforestry) as sources of fibre. However, these species have not been selectivel bred to the degree that they would be considered domesticated.
How big should a dairy cow be?
A mature dairy cow should have a space of at least 11 m 2 , and a pregnant cow 15 m 2. These dimensions are considered sufficient to allow the cow to groom, get up and lie down, and stretch its limbs.
Why is agriculture important?
Agriculture is a huge and necessary enterprise because it provides food for billions of people. A variety of crops are grown in various parts of the world, many of them domesticated, but only a few key ones account for most of the food production. These are barley, maize, manioc, potato, rice, sorghum, soybean, sweet potato, and wheat. Much environmental damage is associated with agriculture, including pollution, degraded land capability, and the destruction of natural habitats. In addition, livestock are not treated well in the industrial agro-food system, often being subjected to unnecessarily inhumane conditions while being reared, transported, or slaughtered. Much of the damage associated with agriculture can be avoided by using more organic means of production and processing. This is the major environmental advantage of organic foods, along with a perception of health benefits by many consumers. Although organic foods are usually somewhat more expensive to purchase, the price differential is more than offset by the environmental benefits from improved stewardship of land, the conservation of resources, and decreased pollution.
How have crops been domesticated?
Domestication refers to the progressive modification of crops through the selective breeding of cultivated races (or cultivars ), which are now genetically, anatomically, and physiologically different from their wild ancestors. Crop plants have been selectively bred to increase their yield and response to management practices and to enhance their palatability. In some cases, thousands of years of domestication have resulted in crop plants that bear so little resemblance to their wild ancestors that they are now incapable of maintaining themselves in the absence of management by people. For example, several millennia of selective breeding of maize (corn; Zea mays) have resulted in its cob becoming tightly wrapped within leafy bracts. As a consequence, its seeds are no longer able to scatter from the cob, so they cannot germinate and develop new plants unless assisted to do so by humans.
What is agriculture?
Introduction. Agriculture can be defined as the science, and art, of cultivating the soil, producing crops, and raising livestock. Even relatively simple agricultural practices can greatly increase the production of food, compared with the hunting and gathering of wild animals and plants.
Environment and Agriculture (PSLA)
Both locally and internationally, there is increasing concern about how humans manage soils, use water, raise animals, and modify the genetic base of crops. This concentration prepares students to work in agroecology, agricultural land management and conservation, sustainable agriculture, integrated pest management, and production science.

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.
Where does nitrogen come from in fertilizer?
Roughly half the nitrogen in synthetic fertilizers escapes from the fields where it is applied, finding its way into the soil, air, water, and rainfall. After soil bacteria convert fertilizer nitrogen into nitrates, rainstorms or irrigation systems carry these toxins into groundwater and river systems.
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.

- Declining Site Capability
Agricultural site capability (or site quality) refers to the ability of an ecosystem to sustain the productivity of crops (Chapter 14). Soil fertility is an important aspect of this – it is related to the amount of nutrients present and to factors affecting their availability, such as drainage, tilth, an… - Pollution Caused by Agriculture
Groundwater and surface waters can become polluted by runoff containing fertilizer, pesticides, and livestock sewage. Inputs of nutrients and organic matter from fertilizer and sewage can cause severe ecological damage to surface waters through eutrophication and oxygen depletion…
