The use of irrigation in ancient times has affected the way we grow crops today. Irrigation has been used for many centuries to get the water from a river to the crops. Today, we also use this way of watering crops. With the use of irrigation crops are able to be grown in larger amounts. In Sandra Postel’s article “Growing more Food with less Water” uses facts to explain how the use of irrigation is very effective in growing more food. The quote “Most of these people live in Asia and Africa, where long dry seasons make crop production difficult or impossible without irrigation” shows that many countries depend on irrigation to survive. (Postel 7) In many countries they depend on rivers to get the water they need to the crops. Since there isn’t much rain in countries like Asia Africa they need any form of irrigation they can use. It is important for these countries survival that they use irrigation. Many irrigation systems are very expensive so many farmers in poorer countries cannot afford them. Recently, a new machine has been created which is very inexpensive and farmers can afford the new irrigation machine. “Over the next quarter of a century the number of people living in water-stressed countries will climb from 500 million to three billion. New technologies can help farmers around the world supply food for the growing population…” This quote shows how new irrigation technology can help farmers have a surplus in crops. (Postel 8) New, cheap, irrigation methods have provided farmers with the technology necessary to grow and water crops. New irrigation methods have helped farmers provide markets with crops which increased their income. The quote “Fields are flooded or water is…
Food and Farming
December 12, 2011
There are many different types of farming methods that are used today, all of which have diverse positives and negatives. As Secretary of the Department of Agriculture I am designing a new program that combines the best points of two existing programs. These two programs, factory farming and organic farming, when united can create a more sustainable and ethical way of farming. Added guidelines, precautions, and laws…
them), heavy use of irrigation, intercropping and vertical farming, and integration. The food we find in shopping markets and that the FDA has passed has been known as ‘Generally Recognized as Safe. “The status, established by Congress in 1958, was granted to additives that had previously existed in the food supply based on unmonitored, inadequate, hit-or-miss surveys and non-existent followups.” (Deville 60).
The history of organic begins with the starting grounds of agriculture. The term itself…
Throughout the years, American agriculture has expanded and developed a multitude of ways. It experienced extremely noticeable changes from the years 1865-1900. These changes included involvement of new technology, government policy, and economic conditions in order to deliver positive or negative aftereffects to American agriculture. The information provided by the documents help support the time periods’ changes. As always, the varying time periods throughout history introduce new…
the growing global population we will need to produce 60 per cent more food by the middle of this century. That is a challenge that cannot be taken too lightly given the increased competition for ever scarcer land and water. To compound matters, agriculture is under great pressure to increase its sustainability.
The solutions are, as always, complicated, mired in economic, political and social wrangling. But one thing is apparent: technology has a key role to play. Engineering is often overlooked…
climate, threaten hundreds of millions of dollars in an agricultural production.
Q2. To support the irrigation systems, the natural landscape is changed, dams and channels are built and paddocks are leveled to move water from natural waterways to agricultural production areas.
Q3. Salinity occurs if groundwater rises, generally when excess water is added to groundwater supplies, such as through irrigation. As the watertable reaches the surface, waterlogging become apparent and water and salt emerge through…
birthday parties, horseback riding, horse boarding, photo shoots and food preservation classes. Their horseback riding and other classes are year round and all done on the farm. They also have summer camp that teaches campers the importance of agriculture. Campers learn about farm life and work with large and small animals understanding what it takes & how to care for them. However, the farm’s main operation is beef cattle. From selling and breeding, Tap Root Farm ensures its customers the satisfaction…
impossibility but it is quickly becoming our reality. The disappearance of honey bees means the loss of hundreds for foods that we enjoy on a daily bases. “Beemageddon”, as some are calling it, could cause the collapse of the 200 billion dollar agriculture industry, since more than 100 US crops rely on honey bees to pollinate them,” (USDA Office of Communications , 2013
For centuries mankind has used farming to help nourish its populations. Humanity has relied on the Earth to provide, time and time…

Agriculture In India – Introduction
Agriculture has been an integral part of the Indian Economy, before and after Independence, despite its decline in share of GDP (17.2% as of 2011). Half of India’s population depends on Agriculture as a livelihood. India is 2nd in farm output. It the largest producer of coriander, spices, millets and many more; second in fruits such as mangoes and papaya; and third in rapeseed, tomatoes and coconuts. Yet 1/3rd of Indian population is under poverty line.
