What is farm policy?
Farm policy. There’s a transformation taking place on farms across the United States. For decades, we’ve produced the bulk of our food through industrial agriculture—a system dominated by large farms growing the same crops year after year, using enormous amounts of chemical pesticides and fertilizers that damage soils, water, air, and climate. …
How do crops protect soil?
These crops protect and build soil health by preventing erosion, replenishing soil nutrients, and keeping weeds in check, reducing the need for herbicides. Reducing or eliminating tillage. Traditional plowing (tillage) prepares fields for planting and prevents weed problems, but can cause a lot of soil loss.
How does industrial agriculture help animals?
Industrial agriculture tends to keep plant and animal production separate, with animals living far from the areas where their feed is produced, and crops growing far away from abundant manure fertilizers.

Who coined the phrase “sustainable agriculture”?
The phrase ‘sustainable agriculture’ was reportedly coined by the Australian agronomist Gordon McClymont.
What is sustainable intensification?
Sustainable intensification encompasses specific agriculture methods that increase production and at the same time help improve environmental outcomes. The desired outcomes of the farm are achieved without the need for more land cultivation or destruction of natural habitat; the system performance is upgraded with no net environmental cost. Sustainable Intensification has become a priority for the United Nations. Sustainable intensification differs from prior intensification methods by specifically placing importance on broader environmental outcomes. By the year 2018; it was predicted in 100 nations a combined total of 163 million farms used sustainable intensification. The amount of agricultural land covered by this is 453 million ha of land. That amount of land is equal to 29% of farms worldwide. In light of concerns about food security, human population growth and dwindling land suitable for agriculture, sustainable intensive farming practises are needed to maintain high crop yields, while maintaining soil health and ecosystem services. The capacity for ecosystem services to be strong enough to allow a reduction in use of non-renewable inputs whilst maintaining or boosting yields has been the subject of much debate. Recent work in irrigated rice production system of east Asia has suggested that – in relation to pest management at least – promoting the ecosystem service of biological control using nectar plants can reduce the need for insecticides by 70% whilst delivering a 5% yield advantage compared with standard practice.

How did Native Americans practice sustainable agriculture?
Native Americans in the United States practiced sustainable agriculture through their subsistence farming techniques. Many tribes grew or harvested their own food from plants that thrived in their local ecosystems. Native American farming practices are specific to local environments and work with natural processes. This is a practice called Permaculture, and it involves a deep understanding of the local environment. Native American farming techniques also incorporate local biodiversity into many of their practices, which helps the land remain healthy.

Who developed the global food system?
The basics of the global food system, which today feeds seven to eight billion people, were developed by the ancient Romans. Their model of mono-crop, broadacre export agriculture has been taken up worldwide, with science and machinery substituting for the slave labor and manual methods of the ancient world, to boost its yields of food in the modern era. It has been phenomenally successful—being the chief driver—coupled with vaccines, antibiotics and public health—in a tripling of the human population since the mid twentieth century.
Is the food system on the way out?
A warning that the present food system is on the way out was clearly articulated by a conference of food scientists from 17 countries held in Sydney in 2016. It concluded: Access to diverse nutritious food and potable water is a right for all life.
Is agriculture the only way to produce food in the future?
However, to assume that, because it was successful in the past, agriculture is the only way to produce food in the future is, at best, sentimental nonsense—and at worst, perilously unrealistic on an overheated, over-populated, over-exploited planet. What has changed is the sheer vastness of the human impact on the Earth.

Why are antibiotics not used in agriculture?
Antibiotic Resistance: Because antibiotics are not used for preventive medicine in sustainable agriculture, implementing sustainable methods of production increases the effectiveness of antibiotics in treating people. Pandemics: Industrial agriculture, in which animals are kept in tight quarters, is a driver of disease.
Why do farmers use the same land to raise livestock and crops?
Using the same land to raise livestock and crops reduces the need for fertilizers, as the manure from the cattle provides nutrients to the plants. This practice also helps control soil erosion and has no impact on crop yield.
How does agriculture affect the environment?
Environmental Impacts. Industrial agriculture is a driving force behind water pollution, soil degradation, and air pollution. The animals housed in CAFOs produce tons of manure every year which is either stored or applied to fields as a fertilizer.

Definition
In the National Agricultural Research, Extension, and Teaching Policy Act of 1977, the term “sustainable agriculture” is defined as an integrated system of plant and animal production practices having a site-specific application that will, over the long term:
• satisfy human food and fiber needs
• enhance environmental quality and the natural resource base upon which the agriculture economy depends
Factors affecting sustainability
Practices that can cause long-term damage to soil include excessive tilling of the soil (leading to erosion) and irrigation without adequate drainage (leading to salinization).
The most important factors for a farming site are climate, soil, nutrients and water resources. Of the four, water and soil conservation are the most amenable to h…
Economics
Costs, such as environmental problems, not covered in traditional accounting systems (which take into account only the direct costs of production incurred by the farmer) are known as externalities.
Netting studied sustainability and intensive agriculture in smallholder systems through history.
There are several studies incorporating externalities such as ecosystem services, biodiversity, land degradation, and sustainable land management in economic analysis. These include The Ec…
Methods
Other practices include growing a diverse number of perennial crops in a single field, each of which would grow in separate season so as not to compete with each other for natural resources. This system would result in increased resistance to diseases and decreased effects of erosion and loss of nutrients in soil. Nitrogen fixation from legumes, for example, used in conjunction with plan…
Social factors
