Agriculture is the science, art and practice of cultivating plants and livestock. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least , years ago, nascent farmers began to plant them around 11, years ago. Pigs, sheep and cattle were domesticated over 10, years ago.


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. To stress the interactions between society and the environment, the driving forces D , pressures P , states S , impacts I , and response R DPSIR framework approach was used for analyzing and assessing the influence of agriculture on land use, environment, and ecosystem services. The DPSIR model was used to identify a series of core indicators and to establish the nature of interactions between different driving forces, pressures, states, impacts, and responses. We assessed selected indicators at global, national, and local levels. The driving forces exert pressure on the environment assessed by indicators describing development in fertilizer and pesticides consumption, by number of livestock, and by intensification joined growing release of ammonia and greenhouse gas GHG emissions from agriculture, and water abstraction.

Intensive agriculture , also known as intensive farming as opposed to extensive farming and industrial agriculture , is a type of agriculture , both of crop plants and of animals , with higher levels of input and output per unit of agricultural land area. It is characterized by a low fallow ratio, higher use of inputs such as capital and labour , and higher crop yields per unit land area. Most commercial agriculture is intensive in one or more ways. Forms that rely heavily on industrial methods are often called industrial agriculture, which is characterised by innovations designed to increase yield. Techniques include planting multiple crops per year, reducing the frequency of fallow years, and improving cultivars.

Environmental Impacts of Agricultural Modifications

The industrialization of agriculture began after World War II, as a way of addressing global hunger and making the food supply more efficient and safe. The global shift towards this model of farming in the last sixty years has come with many costs. Industrialized agriculture is highly concentrated and mechanized, relying on chemical inputs like fertilizers, pesticides and non-therapeutic antibiotics. However, sustainable agriculture , which uses methods that protect the environment, public health, human communities and animal welfare , is gaining traction. The US has always been a nation quick to embrace technology and industrialization. There were too many farmers working the land, a short supply of the workers needed in factories, and too much diversification rather than efficient specialization.

More than half the planet's suitable land has been cultivated for crops, like these terraced rice fields in Bali, Indonesia.

Monday, May 11, At each stage, innovations in farming techniques brought about huge increases in crop yields by area of arable land.

The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice. Farming communities that try to reduce environmental impacts through modifying their practices will adopt sustainable agriculture practices. Though some pastoralism is environmentally positive, modern animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. When evaluating environmental impact, experts use two types of indicators: "means-based", which is based on the farmer's production methods, and "effect-based", which is the impact that farming methods have on the farming system or on emissions to the environment. An example of a means-based indicator would be the quality of groundwater, that is effected by the amount of nitrogen applied to the soil. An indicator reflecting the loss of nitrate to groundwater would be effect-based.

As part of modern farming practices, seed beds are tilled, i.e. the soil is ploughed using The effects of intensive agriculture on terrestrial and aquatic systems are water/quality/nitrate/pdf/consultation-supportdocs/

Sustainable Agriculture vs. Industrial Agriculture

Этот прибор он купил в магазине электроники, оплатив покупку наличными, чтобы сохранить анонимность. Никто лучше его не знал, как тщательно следило агентство за своими сотрудниками, поэтому сообщения, приходящие на этот пейджер, как и отправляемые с него, Стратмор старательно оберегал от чужих глаз. Сьюзан опасливо огляделась. Если до этого Хейл не знал, что они идут, то теперь отлично это понял.

Я просто не желаю играть вторую скрипку - тем более по отношению к подростку. - Моя жена вовсе не подросток, - возмутился Бринкерхофф.  - Она просто так себя ведет. Мидж посмотрела на него с удивлением.

Беккер еще раз просмотрел сообщение. - Нет. Они сказали - агентство. АНБ.

Фонтейн молча обдумывал информацию. - Не знаю, ключ ли это, - сказал Джабба.  - Мне кажется маловероятным, что Танкадо использовал непроизвольный набор знаков. - Выбросьте пробелы и наберите ключ! - не сдержался Бринкерхофф. Фонтейн повернулся к Сьюзан.

    Agriculture is an important source of livelihood because it is the process of producing food, feed, fiber, and many other desired products by the cultivation of plants and the raising of domesticated animals livestock.

    PDF | This research is a comparative study on the effect of modern agricultural methods and the farming system on the environment. Nigeria has fertile humus soil in most parts of the country and where the soil is not humus.

    Traditional agriculture is an extractable process where all resources — human, water, and land — are taken and applied to immediate use.

    Climate change negatively affects all four pillars of food security: availability, access, utilisation and stability.
