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

Drip irrigation is water saving, efficient and effective watering system .The article focuses on the different aspects of the drip irrigation system, its contribution in poverty alleviation and the social economic and environmental impacts of this technology.
Subsurface drip irrigation or SDI is another way of terming a drip irrigation system. As stated by C. Shock, drip irrigation is the slow even application of low-pressure water to soil and plants using plastic tubing placed near the plants’ root zone [8]. Water is supplied to the soil at very low rates from the system of the plastic tubing pipes which are fitted with emitters at the ends. Therefore loss of water through evaporation, water run-off and percolation is minimized to a great extent. Also water contact with the stems, leaves and fruits of the plant is reduced which helps in prevention of formation of disease on the plant. Since the tubing is buried under the soil, it is less at risk of damage due to weeding and cultivation activities.
Designing a subsurface drip system requires an experienced qualified designer. As G. Harris has stated, proper hydraulic design is the initial step in installing a successful SDI system [5]. This will ensure that the system effectively deals with the constraints imposed by the crop and soil characteristics, field size, topography, water supply and shape. The system must be capable of meeting the crop water need during the peak
Arizona farmers are resistant to drip irrigation and prefer flood or rainwater-propelled irrigation, which is used on about 95 percent of Arizona crops. “Farmers have a hard time justifying drip irrigation because water is relatively cheap and drip systems can cost from $500 to $2,000 per acre to install” (U.S. Water News Online). Unfortunately cost is a prohibition not only for farmers but for private residents as well. Many residents have migrated to Arizona due to the region's affordable prices. One of the major problems our towns are facing is the conversion of homes to a more environmentally sound energy models that currently are extremely expensive.
The team specializes in drip irrigation to ensure the landscape remains beautiful months and years after the work is complete. Homeowners find the team harmonizes nature, art and science in ways many never imagined possible and can bring a native, European or woodland garden to any backyard, along with focal points and water features, such as garden ornaments and seating.
Surface Irrigation - Basins or trenches with water flowing - due to gravity - in between rows of crops. [17]
The water shortages in California are causing hardships on the agricultural industry. There isn’t enough fresh water to support both the human population and the natural environment. One way to prevent water shortages would be to improve the irrigation systems the farmers use. Instead of using various types of irrigation systems that waterlog the soil, they should increase the use of a drip-irrigation system.
However, many of the worlds irrigation systems are found in arid, semi arid environments, which climate change will alter significantly in the future (J. D, Connor, Schwabe, K. King, D. Knapp, K. 2011). Nearly one third of the worlds Nearly one-third of the irrigated land worldwide are affected by salinization (Schwabe et al., 2011e).
Irrigation is the best way to care for the lawn, plants, and landscaping. There are many benefits that come from providing water in this way. Watering with the hose can
(Hasan and Özay 2002, 73-74). As Albiac (2008) reports, development of pipe network distribution and drip irrigation methods in other countries led the farmers to have remarkable irrigation efficiency in drought (143). Such technologies have already been used in China, but they are not widely spread in China’s agriculture. One investigation in China on rice paddy irrigation systems development was performed and it revealed that using the fry-foot paddy irrigation (when no water flooded the field) instead of flooding irrigation (when the rice field is completely flooded) significantly (40-60%) reduces water consumption (Xiaoping, Qiangsheng and Bin 2004, 351). Furthermore, drip irrigation method was applied in arid Northern China and it raised the water usage efficiency (Du et al 2007). However, introduction of new irrigation technologies faced some difficulties in China. As Hodstedt (2010) noticed in his article, the water saved by these technologies such as drip irrigation systems was simply spent on more food production and, therefore, did not reduce the water shortage. Also, as he reported, this caused two other environmental problems. Firstly, the water, which was the supply for underground water and aquifers as it was lost by deep percolation and leakage, became unavailable after the water-saving technologies were introduced and this strengthened the aquifers depleting along with its overpumping. Secondly, after
Irrigation is the artificial application of water to the land. Farmers no longer have to rely on direct, and sometimes insufficient rainfall to water crops. Perennial irrigation was practiced in the Mesopotamian plain where crops were regularly watered throughout the growing season by water traveling through small channels that were dug in fields.
Catchments are depended on by the average household person, but even more valuable to the farmers that are supplying the food to our nation. Therefore, action must be taken to ensure that the catchments in our areas are healthy and will be able to be depended on for years to come. The panel at Healthy Water Ways program has developed a study to guarantee the management and sustainability of The Pioneer River catchment, by sending a team out to analyze the health of the water ways and decide on a proposal that best suits the area to ensure future healthiness of the basin.
Yuma and some surroundings agricultural areas are a flooding plain. This makes the soil very fertile and good for planting many different vegetables and plants. Yuma has virtually 3 days of sunshine with sparse mounts of rain. The Colorado river is very close to Yuma, at a couple points crossing through it. This serves as a main source of water for the acres of farming land available. “I stopped at Yuma on my return from Colorado to examine the conditions under which irrigation has been practiced on the Algodones Grant with a view to determine whether or not gravity canals are likely to prove feasible for the general irrigation of that district, as against pumping. The following report has been prepared to embody my conclusions on the matter.
Introduction: Drought affects our lives in many different ways because water is such an important part of many of the activities we do everyday. We all need water to live including animals and plants. We need water to grow out food that we eat. We also use water for many different things in our lives, like washing dishes, cooking, bathing, and swimming or river rafting, which tells water is very important for us to survive. But now not having enough water for all this activities because of drought, it leaves many bad effects our community
India is a developing country. The illiteracy rate there is comparatively high. Also water has been a main concern there. Even though the rate of urbanization in India is among the lowest in the world, the nation has more than 250 million city-dwellers. Experts predict that this number will rise even further, and by 2020, about 50 per cent of India's population will be living in cities. This is going to put further pressure on the already strained centralized water supply systems of urban areas. (http://www.rainwaterharvesting.org/Crisis/Urbanwater-scenario.htm) According to Central Public Health Engineering Organization (CPHEEO) estimates, as on 31 March 2000, 88 per cent of urban population has access to a potable water supply. But this supply is highly erratic and unreliable. Transmission and distribution networks are old and poorly maintained, and generally not trustworthy. The proper conservation of the water is one of the crises that need to be solved immediately else serious consequences may follow. Rain water harvesting in this prospect seems a very
One of the biggest advancements in technology due to agriculture is the irrigation system. The
Because of climate change, activity of droughts are predicted to be an increase in rained rice-growing areas and droughts and maybe into water-short irrigated areas.
Inefficient irrigation techniques allow most of the water provided to crops to evaporate or to miss crop roots entirely as it seeps underground. Despite the wasteful ways with which we treat water, a quarter of the world’s people face water shortages (Watkins et al. 2006). This proportion will only continue to grow, particularly in the Middle East and Northern Africa (Bureau and Strobl 2012).
