The article evaluates the efficiency, effectiveness, social, economic and environmental impacts of the drip irrigation system. The drip irrigation system has the potential to increase the agricultural productivity and also to reduce water usage required for irrigation. It is a system of pipes and tubing located under the soil. Water is passed through these pipes which end at near the roots of the plants. This makes the water loss minimal. Initial stage is designing the system and its installation follows it. The article states the advantages and disadvantages of the system and also cites evidence with regard to the social, economic and environmental aspects.

Poverty is one of the primary concerns the world faces in its road to development. Eradication of poverty tends to be the prime aims of governments worldwide. Lack of proper nutrition is a major cause contributing to poverty. Improving agricultural standards can help in producing more food and thus counter the lack of food factor. One way to improve agricultural standards is to develop the irrigation methods used. Irrigation is closely related to poverty. Irrigation benefits the poor through higher production, higher yields, low risk of crop failure and higher and year round farm and non-farm employment. Irrigation leads to high value market oriented agricultural production [1]. However, in developing countries like India, the agricultural sector is heavily dependent on the south-west monsoons. In view of the rising temperatures worldwide due to global warming and changes of weather patterns associated with it, dependence on rains is not always a possible solution. Failure of proper rains can cripple the agricultural sector which can lead to an overall rise in poverty. Thus...

In this essay, the author

  • Evaluates the efficiency, effectiveness, social, economic, and environmental impacts of the drip irrigation system. it is a system of pipes and tubing located under the soil.
  • Explains that poverty is one of the primary concerns the world faces in its road to development. improving agricultural standards can help in producing more food and counter the lack of food factor.
  • Explains that subsurface drip irrigation or sdi is a slow, even application of low-pressure water to soil and plants using plastic tubing placed near the plants’ root zone.
  • Explains that proper hydraulic design is the initial step in installing a successful sdi system. the optimal tube spacing is determined by soil characteristics and the depth of tube placement.
  • Explains that proper installation ensures that the system performs optimally and determines the life of the sdi system.
  • Explains that drip irrigation systems require 30% less water compared to sprinkler irrigation for cultivating corn in virginia and cotton in hawaii.
  • Explains that drip irrigation systems are suited to farms with uneven topography or soil texture.
  • Explains the disadvantages of the drip irrigation system, such as the initial investment is quite high and the emitters can get clogged frequently and cleaning it is a costly and time-consuming process.
  • Explains that irrigation can transform society as well as land and landscapes. it helps in alleviating poverty in irrigated areas, minimizes the differential distribution of benefits across farmers, and increases social benefits.
  • Explains that drip irrigation systems have helped farmers to attain better profits due to higher yields.
  • Explains that drip irrigation improves soil surface and environment by allowing pretreated coalbed methane waters to flow into the root zone of an agricultural field.
  • Concludes that the drip irrigation system is an effective way of irrigation. it saves on water usage and allows farmers to increase their farm output.
  • Cites i. hussain and m. a. hanjra, "irrigation and poverty alleviation: review of the empirical evidence," int.
  • Cites casewell et al., "economic implications of drip irrigation," california agriculture, pp.4-5, july, 1984. harris, g.
  • Describes the environmental, economic and social impacts of irrigation in the mackenzie basin.
  • Describes the effects of subsurface drip irrigation on processing tomato yield, water table depth, soil salinity, and profitability.
