The importance of irrigation can be explained in the following points:

  • Insufficient and uncertain rainfall adversely affects agriculture. …
  • The productivity on irrigated land is higher as compared to the un-irrigated land.

Does agriculture use large amounts of water for irrigation?

Agriculture is a major user of ground and surface water in the United States, and irrigation has enhanced both the productivity and profitability of the agricultural sector. According to the 2017 Census of Agriculture, farms with some form of irrigation accounted for more than 54 percent of the total value of U.S. crop sales, while irrigated land accounted for less than 20 percent of harvested …

What are the sources of irrigation for farmers?

  • Well
  • Pond
  • Stream

Why is irrigation important to agriculture?

Water applied as irrigation allows for crop production in arid regions and supplements soil moisture in humid regions when growing season precipitation is insufficient. Irrigation has enhanced both the productivity and profitability of the agricultural sector.


Why is irrigation needed for agricultural development in India?

Irrigation is important to a country like India because rainfall here is seasonal in nature. It is limited to four months of a year. It is also important because some crops require more water than what it is provided by the rainfall, therefore we have to depend on irrigation.


Why do we need irrigation?

Places that have sparse or seasonal rainfall could not sustain agriculture without irrigation. In areas that have irregular precipitation, irrigation improves crop growth and quality. By allowing farmers to grow crops on a consistent schedule, irrigation also creates more reliable food supplies.


Why is irrigation development an important component of agricultural development in developing countries?

Irrigation increases agricultural production through both the expansion of cultivable area beyond that possible under rainfed agriculture and higher crop yields.


Why is irrigation necessary in India explain any three reasons Class 12?

(i) Due to irrigation high yielding crops are grown even when there is low and uncertain rainfall. (ii) Irrigation enhances agricultural productivity and it also promotes stability in the production of crops.


Why is irrigation important class 9?

Answer: Irrigation helps to cultivate superior crops with the water supply as per the need of the crops.


What is irrigation in agriculture?

Irrigation is the artificial application of water to the soil through various systems of tubes, pumps, and sprays. Irrigation is usually used in areas where rainfall is irregular or dry times or drought is expected. There are many types of irrigation systems, in which water is supplied to the entire field uniformly.


Abstract

We examine the role of irrigation in explaining U.S. agricultural gains post-1940. Specifically, we analyze how productivity and farm values changed in the western United States as a result of technological and policy changes that expanded access to ground and surface water.


Background and Literature

With a few exceptions, precipitation in the United States west of the 98 th Meridian is not sufficient for intensive agricultural production. While the ability of the region to support agriculture was questioned initially, early settlement in areas with access to water demonstrated that agricultural production was possible.


Data

For our analysis, we construct a panel data set consisting of 2,920 U.S. counties with 18 observations from 1910 to 2007. Our main analysis, however, uses only the subsample from the arid 17 western states.


Empirical Model

To explore the differential influence of groundwater and expanded surface water access, we would like to run the following regression:


Results

Results for the primary specification, with and without county fixed effects, are provided in Table 2. We focus on Panel A because the estimated impacts for post-1940 are quite stable between the models, and foregoing fixed effects exposes an interesting result in the 1910–1940 period.


Discussion and Conclusion

Over the 100 years examined, additional water access provided substantial gains in productivity and value for the arid West.

Why is irrigation important in agriculture?

The importance of irrigation in agriculture and proper water storage. Water, an essential resource for crop production, is an increasingly scarce asset, while the area devoted to crops continues to grow due to the progressive increase in the world’s population .


Where does agricultural water come from?

The water destined for agricultural use is obtained from rivers, lakes, wells, sewage treatment plants, and by seawater desalination processes, as well as from water reservoirs or rafts in those places where a constant flow is not available.


How much water is needed to produce wheat?

And, if we consider that to produce a kilogram of wheat (including straw and grain), it is necessary to consume about 450 liters of water, and that a person’s food requires 0.23 hectares and 3,000 liters per day for its production, we realize the enormous amount of water that must be used for agricultural use.


Abstract and Figures

The agricultural sector has strategic priorities in terms of nutrition. Increasing demand for food because of population growth in the world increases the need for agricultural products and obligates the sustainability of agricultural enterprises, the agricultural sector. Agricultural sustainability; economic, technical, central, legal and social.

How many hectares of land were affected by water logging in 1991?

The working group constituted by the Ministry of Water Resources in 1991 estimated that about 2.46 million hectares in irrigated commands suffered from water logging. The working group also estimated that 3.30 million hectares had been affected by salinity/alkalinity in the irrigated commands.


Why is Indian agriculture called a gamble in the monsoon?

That is why Indian agriculture is called a gamble in the monsoon. 1. Insufficient, uncertain and irregular rain causes uncertainty in agriculture. The period of rain is restricted to only four months in a year, June to September, when monsoon arrives.


How much of the land is dependent on rain?

Despite large-scale investment and expansion of irrigation facilities, it is a matter of serious concern that about 60 per cent of the total cropped area is still dependent on rain. There are a number of problems related to irrigation and they have to be solved.


How much of India’s water is canalized?

Approximately 31% of the irrigated areas in India is watered by canals. This includes large areas of land in Punjab, Haryana, Uttar Pradesh, Bihar and parts of southern states. Wells are now spread over large areas of Punjab, Uttar Pradesh, Bihar, Rajasthan and Tamil Nadu.


Can monsoons cause droughts?

This pushes large areas of the country into drought conditions. With the help of irrigation, droughts and famines can be effectively controlled.


Can India grow crops year round?

Multiple cropping possible: Since India has a tropical and sub-tropical climate, it has potentialities to grow crops on a year-round basis. However, since 80% of the annual rainfall is received in less than four months, multiple cropping is generally not possible.


Is irrigation a state subject in India?

In most of the projects, there have been delays in construction of field channels and water courses, land leveling and land shaping. Irrigation is a state subject in India. Development of water resource is, therefore, being planned by states individually taking into account their own needs and requirement.
