Dem set up de first Belgian outposts for de lake top at Lukonzolwa den Pweto wey dey at various times de headquarters of demma administration of Katanga. Dem stamp out de slave trade wey dey go north-east around de lake.

De British move demma [[:en:Boma_(enclosure)|boma]] from [[:en:Chiengi|Chiengi]] to de Kalungwishi, plus one anaa two British officers (such as [[:en:Blair_Watson|Blair Watson]]), den a force of African police. For conjunction insyd plus operations around [[:en:Mbala,_Zambia|Abercorn]] further down de trade route, dis dey enough to end de slave trade wey dey go east from Mweru, but no dey enough to bring Mwata Kazembe under British rule, den dem get to send a military expedition for 1899 insyd from [[:en:British_Central_Africa|British Central Africa]] ([[:en:Malawi|Nyasaland]]) to do dat job (see de article for [[:en:Alfred_Sharpe|Alfred Sharpe]] top give more details). De move of de boma from Chiengi to Kalungwishi get de effect of leaving de Belgian boma at Pweto a free rein at de northern end of de lake, wey e lead a hundred years later to about {{convert|33|km2}} of Zambian territory next to Pweto being ceded to de DR Congo (then Zaire).

Dem set up de first Belgian outposts for de lake top at Lukonzolwa den Pweto wey dey at various times de headquarters of demma administration of Katanga. Dem stamp out de slave trade wey dey go north-east around de lake. Scottish missionary [[:en:Dan_Crawford_(missionary)|Dan Crawford]] of de [[:en:Plymouth_Brethren|Plymouth Brethren]] establish de first mission station for de lake top for 1892 insyd at Luanza for de Belgian side of de lake top. De British move demma [[:en:Boma_(enclosure)|boma]] from [[:en:Chiengi|Chiengi]] to de Kalungwishi, plus one anaa two British officers (such as [[:en:Blair_Watson|Blair Watson]]), den a force of African police. For conjunction insyd plus operations around [[:en:Mbala,_Zambia|Abercorn]] further down de trade route, dis dey enough to end de slave trade wey dey go east from Mweru, but no dey enough to bring Mwata Kazembe under British rule, den dem get to send a military expedition for 1899 insyd from [[:en:British_Central_Africa|British Central Africa]] ([[:en:Malawi|Nyasaland]]) to do dat job (see de article for [[:en:Alfred_Sharpe|Alfred Sharpe]] top give more details). De move of de boma from Chiengi to Kalungwishi get de effect of leaving de Belgian boma at Pweto a free rein at de northern end of de lake, wey e lead a hundred years later to about {{convert|33|km2}} of Zambian territory next to Pweto being ceded to de DR Congo (then Zaire).

Dem set up de first Belgian outposts for de lake top at Lukonzolwa den Pweto wey dey at various times de headquarters of demma administration of Katanga. Dem stamp out de slave trade wey dey go north-east around de lake.

Dem set up de first Belgian outposts for de lake top at Lukonzolwa den Pweto wey dey at various times de headquarters of demma administration of Katanga. Dem stamp out de slave trade wey dey go north-east around de lake.

For conjunction insyd plus operations around [[:en:Mbala,_Zambia|Abercorn]] further down de trade route, dis dey enough to end de slave trade wey dey go east from Mweru, but no dey enough to bring Mwata Kazembe under British rule, den dem get to send a military expedition for 1899 insyd from [[:en:British_Central_Africa|British Central Africa]] ([[:en:Malawi|Nyasaland]]) to do dat job (see de article for [[:en:Alfred_Sharpe|Alfred Sharpe]] top give more details).

Dem set up de first Belgian outposts for de lake top at Lukonzolwa den Pweto wey dey at various times de headquarters of demma administration of Katanga. Dem stamp out de slave trade wey dey go north-east around de lake. Scottish missionary [[:en:Dan_Crawford_(missionary)|Dan Crawford]] of de [[:en:Plymouth_Brethren|Plymouth Brethren]] establish de first mission station for de lake top for 1892 insyd at Luanza for de Belgian side of de lake top. De British move demma [[:en:Boma_(enclosure)|boma]] from [[:en:Chiengi|Chiengi]] to de Kalungwishi, plus one anaa two British officers (such as [[:en:Blair_Watson|Blair Watson]]), den a force of African police. For conjunction insyd plus operations around [[:en:Mbala,_Zambia|Abercorn]] further down de trade route, dis dey enough to end de slave trade wey dey go east from Mweru, but no dey enough to bring Mwata Kazembe under British rule, den dem get to send a military expedition for 1899 insyd from [[:en:British_Central_Africa|British Central Africa]] ([[:en:Malawi|Nyasaland]]) to do dat job (see de article for [[:en:Alfred_Sharpe|Alfred Sharpe]] top give more details).

Dem set up de first Belgian outposts for de lake top at Lukonzolwa den Pweto wey dey at various times de headquarters of demma administration of Katanga. Dem stamp out de slave trade wey dey go north-east around de lake.

For conjunction insyd plus operations around [[:en:Mbala,_Zambia|Abercorn]] further down de trade route, dis dey enough to end de slave trade wey dey go east from Mweru, but no dey enough to bring Mwata Kazembe under British rule, den dem get to send a military expedition for 1899 insyd from [[:en:British_Central_Africa|British Central Africa]] ([[:en:Malawi|Nyasaland]]) to do dat job (see de article for [[:en:Alfred_Sharpe|Alfred Sharpe]] top give more details).

Dem set up de first Belgian outposts for de lake top at Lukonzolwa den Pweto wey dey at various times de headquarters of demma administration of Katanga. Dem stamp out de slave trade wey dey go north-east around de lake.

Dem set up de first Belgian outposts for de lake top at Lukonzolwa den Pweto wey dey at various times de headquarters of demma administration of Katanga. Dem stamp out de slave trade wey dey go north-east around de lake. Scottish missionary Dan Crawford of de Plymouth Brethren establish de first mission station for de lake top for 1892 insyd at Luanza for de Belgian side of de lake top. De British move demma boma from Chiengi to de Kalungwishi, plus one anaa two British officers (such as Blair Watson), den a force of African police. For conjunction insyd plus operations around Abercorn further down de trade route, dis dey enough to end de slave trade wey dey go east from Mweru, but no dey enough to bring Mwata Kazembe under British rule, den dem get to send a military expedition for 1899 insyd from British Central Africa (Nyasaland) to do dat job (see de article for Alfred Sharpe top give more details). De move of de boma from Chiengi to Kalungwishi get de effect of leaving de Belgian boma at Pweto a free rein at de northern end of de lake, wey e lead a hundred years later to about {{convert|33|km2}} of Zambian territory next to Pweto be ceded to de DR Congo (then Zaire).

This increase in rainfall link to more vegetation growth, a process wey researchers call the “greening” of the Sahel. Scientists explain the increase in rainfall through stronger African easterly jet winds, wey normally bring wetter conditions. A 2011 study find say changes in the position of the African easterly jet and African easterly waves happen together with the northward movement of the Sahel rainband.<ref name="hindawi.com">[http://www.hindawi.com/journals/ijge/2011/259529/abs/ Wang and Gillies (2011)]</ref> ==History== Because almost all the rain wey fall for Sahel come during one short season every year, the region don always be vulnerable to serious problems whenever drought happen. Agriculture for the area begin around 5,000 years ago. The Sahel usually receive less than {{convert|1000|mm|in|-1|disp=or}} of rain every year, and almost all of am fall during one continuous rainy season wey fit last from a few weeks reach four months. Even though the area be vulnerable to drought, the history of drought and famine for the Sahel no always match perfectly. Modern scientific studies of climate and rainfall don identify several drought periods, but oral traditions and written records from the last thousand years no always report famine everywhere during every drought. One 1997 study wey compare historical famine records with long-term rainfall records for Northern Nigeria conclude say: “The most disruptive historical famines happened when cumulative rainfall shortages pass 1.3 times the standard deviation of long-term average annual rainfall for a particular area.”<ref>Aondover Tarhule1 and Ming-Ko Woo. 'Towards an Interpretation of Historical Droughts in Northern Nigeria' ''Climatic Change'', no 37, 1997. pp.601-613</ref> For example, between 1982 and 1984, the drought be especially destructive for the pastoral Fula people of Senegal, Mali and Niger, as well as the Tuareg people of northern Mali and Niger. These populations no only suffer from the 1968–1974 drought period, but many of them no fit rebuild their livestock herds wey they lose before. Other factors, such as political power shifting to settled populations after independence during the 1960s, problems for Senegal–Mauritania border relations, and Niger’s dependence on falling world uranium prices, all combine to make the famine worse.<ref>David Tenenbaum.

In contrast with earlier studies, which reconstructed wetter conditions in East Africa during this period, evidence from [[Lake Bosumtwi]] supports more recent studies suggesting that this interval was dry. Evidence for LIA drought is not restricted to Africa, however. Records from throughout the tropics, including the western Pacific warm pool, the Arabian Sea, continental Asia, and tropical South America all show evidence for dry conditions during this time period.<ref name="shanahan"/></blockquote> ====1640==== The first major historically recorded drought in the Sahel occurred around 1640.

The 1940s saw several minor droughts — notably in 1949 — but the 1950s were consistently wet, and expansion of agriculture to feed growing populations characterised this decade. Many have thought this contributed to the severity of the subsequent Sahel droughts. ===Late 20th century droughts=== [[Burkina Faso]], northern [[Nigeria]], southern [[Niger]], far northern [[Cameroon]] (near [[Lake Chad]]) and central [[Chad]] all struggled with dwindling rain fall from the 1960s. The 1968-73 drought severely affected several West African countries. Grazing became impossible and this triggered a large-scale famine that led to the first mobilization of external aid and the creation of the [[International Fund for Agricultural Development]] by [[United Nations]]. Up to 100,000 people and a third of livestock died. This drought was so catastrophic that it became known as the "[[Great Sahelian drought]]".<ref>[https://www.wearewater.org/en/the-sahel-desertification-beyond-drought_318262 The Sahel, desertification beyond drought]</ref><ref>[https://cdn.odi.org/media/documents/6718.pdf COPING WITH AFRICAN DROUGHT]</ref><ref>[https://repositorio.esocite.la/465/1/Garcia1981-NaturePleadsNotGuilty.pdf Drought and Man.

The Sahel usually receive less than {{convert|1000|mm|in|-1|disp=or}} of rain every year, and almost all of am fall during one continuous rainy season wey fit last from a few weeks reach four months. Even though the area be vulnerable to drought, the history of drought and famine for the Sahel no always match perfectly. Modern scientific studies of climate and rainfall don identify several drought periods, but oral traditions and written records from the last thousand years no always report famine everywhere during every drought. One 1997 study wey compare historical famine records with long-term rainfall records for Northern Nigeria conclude say: “The most disruptive historical famines happened when cumulative rainfall shortages pass 1.3 times the standard deviation of long-term average annual rainfall for a particular area.”<ref>Aondover Tarhule1 and Ming-Ko Woo.

These populations no only suffer from the 1968–1974 drought period, but many of them no fit rebuild their livestock herds wey they lose before. Other factors, such as political power shifting to settled populations after independence during the 1960s, problems for Senegal–Mauritania border relations, and Niger’s dependence on falling world uranium prices, all combine to make the famine worse.<ref>David Tenenbaum.

Many have thought this contributed to the severity of the subsequent Sahel droughts. ===Late 20th century droughts=== [[Burkina Faso]], northern [[Nigeria]], southern [[Niger]], far northern [[Cameroon]] (near [[Lake Chad]]) and central [[Chad]] all struggled with dwindling rain fall from the 1960s. The 1968-73 drought severely affected several West African countries. Grazing became impossible and this triggered a large-scale famine that led to the first mobilization of external aid and the creation of the [[International Fund for Agricultural Development]] by [[United Nations]]. Up to 100,000 people and a third of livestock died. This drought was so catastrophic that it became known as the "[[Great Sahelian drought]]".<ref>[https://www.wearewater.org/en/the-sahel-desertification-beyond-drought_318262 The Sahel, desertification beyond drought]</ref><ref>[https://cdn.odi.org/media/documents/6718.pdf COPING WITH AFRICAN DROUGHT]</ref><ref>[https://repositorio.esocite.la/465/1/Garcia1981-NaturePleadsNotGuilty.pdf Drought and Man.

People no get money like today, dem dey consume fewer calories and [[meat consumption|dem dey chop less meat]], so water wey dem need to produce food no plenty. At that time, humans dey take about one-third of the water volume wey we dey currently take from rivers. Today, competition for [[water resources]] don become very serious, because population don pass [[population growth|seven billion people]] for earth. This one dey increase chances of [[overconsumption]] of food wey dey need plenty water, especially animal farming and [[intensive farming]] systems. So now, industry, cities (urbanisation), and [[biofuel crops]] all dey compete for same water. Farmers go need try increase productivity to meet growing demand for food, while industries and cities too must find ways to use water more efficiently.<ref>Chartres, C. and Varma, S. ''Out of water. From Abundance to Scarcity and How to Solve the World's Water Problems'', FT Press (USA), 2010</ref> Successful farming depend on whether farmers fit get enough water. But already, [[water scarcity]] dey seriously affect farming for many parts of the world. == Irrigation methods == There are different methods of irrigation. The way water dey reach plants dey differ. The aim be to apply water evenly so that each plant go get wetin e need—no too much, no too small. Irrigation fit also be ''supplementary'' (meaning rain still dey contribute), or it fit be full irrigation where crops almost no depend on rain at all. Full irrigation dey happen mostly for dry (arid) areas or when farming dey happen outside rainy season for semi-arid regions. ===Surface irrigation=== {{Main|Surface irrigation}} [[File:LevelBasinFloodIrrigation.JPG|thumb|Basin flood irrigation of wheat]] Surface irrigation, wey some people dey call gravity irrigation, na the oldest irrigation method wey humans don dey use for thousands of years. For this system (furrow, flood, or level basin irrigation), water dey flow on top of farmland surface, wet the soil, then e go soak enter ground. Water movement dey follow gravity or land slope. Surface irrigation fit be furrow irrigation, border strip irrigation, or basin irrigation. Sometimes people dey call am flood irrigation especially when water cover or nearly cover the farm land. Historically, this na the most common irrigation method for many parts of the world. E cheap to set up and no need plenty energy, but e no too efficient because farmers no dey fully control how water spread. Because of this, surface irrigation dey mostly use for developing countries, low-value crops, and big farmlands. Where water source dey higher than farm land, farmers fit control am with dikes (levees) wey dem dey block with soil. This kind system dey common for terraced rice farming (rice paddies), where water dey carefully control inside each field. Sometimes dem dey pump or lift water using human or animal power. [[File:Residential flood irrigation in Phoenix, Arizona, in the United States of America.jpg|thumb|Residential flood irrigation in Phoenix, Arizona, US]] Surface irrigation still dey use for some urban gardens, for example around Phoenix, Arizona. The irrigated area dey surrounded by berm, and water dey delivered based on schedule wey local irrigation district set.<ref>{{cite web|title=Flood Irrigation Service|url=http://www.tempe.gov/home/showdocument?id=3194|publisher=City of Tempe, Arizona|access-date=29 July 2017}}</ref> One special type of surface irrigation na spate irrigation, wey also dey call floodwater harvesting.

Low application efficiency mean say water wey dem dey use for farm pass wetin crop or field really need. If efficiency increase, e mean say crop production per unit water go increase. Better efficiency fit come when farmer reduce water for same field or use water more wisely, so dem fit get higher yield for same land area. For some places around the world, farmers dey pay for irrigation water, so over-using water go cause direct money loss for dem. Irrigation too dey need pumping energy (electricity or fuel) to move water go field or maintain pressure, so when efficiency improve, water cost and energy cost per unit production go reduce. If one field use less water, farmer fit use the extra water irrigate bigger area, so total production go increase. Low efficiency usually mean say excess water dey lost through seepage or runoff, which fit also carry nutrients or pesticides go outside farm and affect environment badly. Improving irrigation efficiency normally dey happen in two main ways: either dem improve system design or dem improve irrigation management. System design improvement fit include changing from one irrigation type go another (for example from furrow to drip irrigation) or making small adjustments like flow rate and pressure.

People no get money like today, dem dey consume fewer calories and dem dey chop less meat, so water wey dem need to produce food no plenty. At that time, humans dey take about one-third of the water volume wey we dey currently take from rivers. Today, competition for [[water resources]] don become very serious, because population don pass seven billion people for earth. This one dey increase chances of overconsumption of food wey dey need plenty water, especially animal farming and intensive farming systems. So now, industry, cities (urbanisation), and biofuel crops all dey compete for same water. Farmers go need try increase productivity to meet growing demand for food, while industries and cities too must find ways to use water more efficiently.<ref>Chartres, C. and Varma, S. ''Out of water. From Abundance to Scarcity and How to Solve the World's Water Problems'', FT Press (USA), 2010</ref> Successful farming depend on whether farmers fit get enough water. But already, water scarcity dey seriously affect farming for many parts of the world. == Irrigation methods == There are different methods of irrigation. The way water dey reach plants dey differ. The aim be to apply water evenly so that each plant go get wetin e need—no too much, no too small. Irrigation fit also be ''supplementary'' (meaning rain still dey contribute), or it fit be full irrigation where crops almost no depend on rain at all. Full irrigation dey happen mostly for dry (arid) areas or when farming dey happen outside rainy season for semi-arid regions. ===Surface irrigation=== {{Main|Surface irrigation}} [[File:LevelBasinFloodIrrigation.JPG|thumb|Basin flood irrigation of wheat]] Surface irrigation, wey some people dey call gravity irrigation, na the oldest irrigation method wey humans don dey use for thousands of years. For this system (furrow, flood, or level basin irrigation), water dey flow on top of farmland surface, wet the soil, then e go soak enter ground. Water movement dey follow gravity or land slope. Surface irrigation fit be furrow irrigation, border strip irrigation, or basin irrigation. Sometimes people dey call am flood irrigation especially when water cover or nearly cover the farm land. Historically, this na the most common irrigation method for many parts of the world. E cheap to set up and no need plenty energy, but e no too efficient because farmers no dey fully control how water spread. Because of this, surface irrigation dey mostly use for developing countries, low-value crops, and big farmlands. Where water source dey higher than farm land, farmers fit control am with dikes (levees) wey dem dey block with soil. This kind system dey common for terraced rice farming (rice paddies), where water dey carefully control inside each field. Sometimes dem dey pump or lift water using human or animal power. [[File:Residential flood irrigation in Phoenix, Arizona, in the United States of America.jpg|thumb|Residential flood irrigation in Phoenix, Arizona, US]] Surface irrigation still dey use for some urban gardens, for example around Phoenix, Arizona.

When flood happen, water dey diverted into dry river beds (wadis) through dams, gates, and channels, then e spread across large land areas. Later, the moisture inside soil go support crop growth.

This process dem dey call fertigation. Deep percolation (when water go pass root zone enter deep soil) fit happen if drip system run too long or water flow too fast. Drip systems fit range from very high-tech computerized systems to simple low-tech ones wey need manual work. Most times, drip irrigation no need high pressure like other irrigation systems, except low-energy center pivot or surface irrigation systems. The system fit be designed to give equal water everywhere for farm or to give exact water amount to each plant, especially for mixed crops or landscaping.

For this system, dem dey raise underground water level so soil go dey moist from below plant root zone. Some systems dey use canals, pumps, and gates to control water level inside soil through drainage networks. Subirrigation also dey common for greenhouse farming, especially for potted plants. Water dey flow from below, plant dey absorb am, and extra water dey collect for reuse. This system dey save water and nutrients, but e need expensive equipment and careful management.

Low application efficiency mean say water wey dem dey use for farm pass wetin crop or field really need. If efficiency increase, e mean say crop production per unit water go increase. Better efficiency fit come when farmer reduce water for same field or use water more wisely, so dem fit get higher yield for same land area. For some places around the world, farmers dey pay for irrigation water, so over-using water go cause direct money loss for dem. Irrigation too dey need pumping energy (electricity or fuel) to move water go field or maintain pressure, so when efficiency improve, water cost and energy cost per unit production go reduce. If one field use less water, farmer fit use the extra water irrigate bigger area, so total production go increase. Low efficiency usually mean say excess water dey lost through seepage or runoff, which fit also carry nutrients or pesticides go outside farm and affect environment badly. Improving irrigation efficiency normally dey happen in two main ways: either dem improve system design or dem improve irrigation management. System design improvement fit include changing from one irrigation type go another (for example from furrow to drip irrigation) or making small adjustments like flow rate and pressure. Irrigation management dey about how dem schedule watering and decide how much water to apply each time. == Garden irrigation == Domestic gardens and landscaped areas around public buildings dey often get some kind irrigation system especially for dry climates.<ref name=purtill/> For Australia, small garden sprinklers wey dem attach to hose become common irrigation method, and people dey regulate am with sprinkler timer.

The Soviet irrigation push stemmed mainly from their late 19th-century fears of the American cotton monopoly and subsequent desire to achieve cotton self-sufficiency.<ref>[[#refMcNeill2000|McNeill 2000]] p. 163</ref> They had built up their textile manufacturing industry in the 19th century, requiring increased cotton and irrigation, as the region did not receive enough rainfall to support cotton farming.<ref name="ReferenceC" /> The Russians built dams on the [[Don River|Don]] and [[Kuban River|Kuban]] rivers for irrigation, reducing freshwater flow into the [[Sea of Azov]] and making it much saltier. Depletion and salinization also affected other areas of the Russian irrigation project. In the 1950s, Soviet officials began diverting the [[Syr Darya]] and the [[Amu Darya]], which fed the [[Aral Sea]]. Before diversion, the rivers delivered {{convert|55|km3|cumi|0}} of water to the Aral Sea per year, but after diversion they delivered only {{convert|6|km3|cumi|1}}. Because of reduced inflow, the Aral Sea shrank to less than half its original area, making the regional climate more extreme and creating airborne salinization that reduced nearby crop yields.<ref>[[#refMcNeill2000|McNeill 2000]] pp. 164–165.</ref> By 1975, the USSR used eight times as much water as it had in 1913, mostly for irrigation. Irrigated hectares in Central Asia peaked at 7 million. [[Mikhail Gorbachev]] cancelled a proposed plan to reverse the Ob and Yenisei rivers for irrigation in 1986, and the breakup of the USSR in 1991 ended Russian investment in Central Asian cotton irrigation.<ref>[[#refMcNeill2000|McNeill 2000]] p. 166</ref> ==== Africa ==== Various irrigation schemes with different goals and success rates were implemented across Africa in the 20th century, but all were influenced by colonial forces. The [[Tana River Irrigation Scheme]] in eastern [[Kenya]], completed between 1948 and 1963, opened up new land for agriculture. The Kenyan government attempted to resettle the area with detainees from the [[Mau Mau uprising]].<ref>[[#refParker2020|Parker 2020]].</ref> Italian oil drillers discovered Libya’s underground water resources during the [[Italian colonization of Libya]]. This water remained largely unused until 1969, when [[Muammar Gaddafi]] and American businessman [[Armand Hammer]] built the [[Great Man-Made River]] to transport Saharan water to the coast. The project contributed to irrigation but cost four to ten times more than the crops it produced were worth.<ref>[[#refMcNeill2000|McNeill 2000]] p. 155</ref> In 1912, the [[Union of South Africa]] established an irrigation department and began investing in water storage infrastructure and irrigation systems. The government used irrigation and dam-building to pursue social goals such as poverty relief by creating construction jobs for poor whites and developing irrigation schemes to increase white farming. One of the first major projects was the [[Hartbeespoort Dam]], begun in 1916 to improve living conditions for “poor whites” and later completed as a “whites only” employment project.<ref>{{cite book |url=https://muse.jhu.edu/book/60573 |title=White South Africa's 'weak sons': Poor whites and the Hartbeespoort Dam |vauthors=Clynick T |date=2007 |publisher=Wits University Press |isbn=978-1-86814-669-7 |veditors=Esterhuysen A, Jenkins T, Bonner P |pages=248–274 |chapter=A Search for Origins: Science, history and South Africa's "Cradle of Humankind"}}</ref> The [[Pretoria]] irrigation scheme, the Kammanassie project, and the Buchuberg irrigation scheme on the [[Orange River]] followed in the 1920s and 1930s.<ref name="Visser 2018" /> In Egypt, modern irrigation began under [[Muhammad Ali of Egypt|Muhammad Ali Pasha]] in the mid-1800s, who sought economic independence from the [[Ottoman Empire]] through cotton exports.<ref>[[#refRoss2017|Ross 2017]] p. 33.</ref> His administration proposed replacing traditional [[basin irrigation]] with barrages on the lower Nile to support cotton production.

People no get money like today, dem dey consume fewer calories and dem dey chop less meat, so water wey dem need to produce food no plenty. At that time, humans dey take about one-third of the water volume wey we dey currently take from rivers. Today, competition for [[water resources]] don become very serious, because population don pass seven billion people for earth. This one dey increase chances of overconsumption of food wey dey need plenty water, especially animal farming and intensive farming systems. So now, industry, cities (urbanisation), and biofuel crops all dey compete for same water. Farmers go need try increase productivity to meet growing demand for food, while industries and cities too must find ways to use water more efficiently.<ref>Chartres, C. and Varma, S. ''Out of water. From Abundance to Scarcity and How to Solve the World's Water Problems'', FT Press (USA), 2010</ref> Successful farming depend on whether farmers fit get enough water. But already, water scarcity dey seriously affect farming for many parts of the world. == Irrigation methods == There are different methods of irrigation. The way water dey reach plants dey differ. The aim be to apply water evenly so that each plant go get wetin e need—no too much, no too small. Irrigation fit also be ''supplementary'' (meaning rain still dey contribute), or it fit be full irrigation where crops almost no depend on rain at all. Full irrigation dey happen mostly for dry (arid) areas or when farming dey happen outside rainy season for semi-arid regions. ===Surface irrigation=== {{Main|Surface irrigation}} [[File:LevelBasinFloodIrrigation.JPG|thumb|Basin flood irrigation of wheat]] Surface irrigation, wey some people dey call gravity irrigation, na the oldest irrigation method wey humans don dey use for thousands of years. For this system (furrow, flood, or level basin irrigation), water dey flow on top of farmland surface, wet the soil, then e go soak enter ground. Water movement dey follow gravity or land slope. Surface irrigation fit be furrow irrigation, border strip irrigation, or basin irrigation. Sometimes people dey call am flood irrigation especially when water cover or nearly cover the farm land. Historically, this na the most common irrigation method for many parts of the world. E cheap to set up and no need plenty energy, but e no too efficient because farmers no dey fully control how water spread. Because of this, surface irrigation dey mostly use for developing countries, low-value crops, and big farmlands. Where water source dey higher than farm land, farmers fit control am with dikes (levees) wey dem dey block with soil. This kind system dey common for terraced rice farming (rice paddies), where water dey carefully control inside each field. Sometimes dem dey pump or lift water using human or animal power. [[File:Residential flood irrigation in Phoenix, Arizona, in the United States of America.jpg|thumb|Residential flood irrigation in Phoenix, Arizona, US]] Surface irrigation still dey use for some urban gardens, for example around Phoenix, Arizona. The irrigated area dey surrounded by berm, and water dey delivered based on schedule wey local irrigation district set.<ref>{{cite web|title=Flood Irrigation Service|url=http://www.tempe.gov/home/showdocument?id=3194|publisher=City of Tempe, Arizona|access-date=29 July 2017}}</ref> One special type of surface irrigation na spate irrigation, wey also dey call floodwater harvesting. When flood happen, water dey diverted into dry river beds (wadis) through dams, gates, and channels, then e spread across large land areas. Later, the moisture inside soil go support crop growth. Spate irrigation dey common for semi-arid or arid mountainous regions. ===Micro-irrigation=== {{Main|Micro-irrigation}} [[File:Dripperwithdrop.png|thumb|Drip irrigation – a dripper in action]] Micro-irrigation, wey some people dey call localized irrigation, low-volume irrigation, or trickle irrigation, na system wey water dey move through pipes under low pressure and dey release small-small amount directly near each plant.

Field water efficiency for drip irrigation normally dey between 80% to 90% when e dey properly managed. For modern agriculture, drip irrigation dey often combine with plastic mulch, wey dey reduce evaporation even more. E also dey serve as way to deliver fertilizer directly to plants. This process dem dey call fertigation. Deep percolation (when water go pass root zone enter deep soil) fit happen if drip system run too long or water flow too fast. Drip systems fit range from very high-tech computerized systems to simple low-tech ones wey need manual work. Most times, drip irrigation no need high pressure like other irrigation systems, except low-energy center pivot or surface irrigation systems. The system fit be designed to give equal water everywhere for farm or to give exact water amount to each plant, especially for mixed crops or landscaping. Even though e hard small to control pressure for steep land, pressure-compensating emitters dey available, so the system still fit work well even if land no flat. High-tech drip systems dey use carefully measured emitters wey dey connect to pipes and computer-controlled valves for precise water delivery.<ref>{{Cite web |title=Drip Irrigation System for sustainable agriculture |url=https://www.agriculturelandusa.com/2023/07/Drip-Irrigation-system.html |access-date=2024-03-07 |website=Agriculture land usa |archive-date=April 21, 2024 |archive-url=https://web.archive.org/web/20240421164829/https://www.agriculturelandusa.com/2023/07/Drip-Irrigation-system.html |url-status=dead }}</ref> === Sprinkler irrigation === {{Further|Irrigation sprinkler}} [[File:Crop sprinklers Rio Vista California 15 Jul 2004-002.jpg|thumb|Crop sprinklers near Rio Vista, California, US]] [[File:TravellingSprinkler.JPG|thumb|A traveling sprinkler at Millets Farm Centre, Oxfordshire, United Kingdom]] For sprinkler irrigation, water dey go through pipes enter one or more central points for farm, then high-pressure sprinklers or guns go spray am over the crops like rain. Systems wey get sprinklers or sprays wey fixed for poles dem dey call solid-set irrigation systems. Rotating sprinklers (rotors) dey move with ball drive, gear drive, or impact mechanism, and dem fit rotate full circle or half circle. Big “guns” dey similar to rotors but dem dey use very high pressure of {{convert|275|to|900|kPa|psi|abbr=on}} and high water flow of 3 to 76 L/s (50 to 1200 US gal/min), with nozzle sizes between {{convert|10|to|50|mm|in|abbr=on}}. Dem dey also use am for dust control and logging operations. Some sprinkler systems dey mounted on moving platforms wey hose dey supply water. These traveling sprinklers fit move by themselves across small farms, parks, or sports fields without human help. Many use polyethylene tubing wound on steel drum; as e dey roll back, water pressure or engine dey pull am forward. When e reach end, system go stop automatically. Other systems dey use rubber hose wey dey drag behind or cable system wey dey pull platform. ==== Center pivot ==== {{Main|Center pivot irrigation}} Center pivot irrigation na system wey get many pipe sections joined together and supported by wheeled towers. The system dey rotate around central point where water dey enter.

Newer systems dey use drop sprinkler heads wey hang down near crops to reduce water loss through evaporation. As of {{As of|2017}}, many systems dey use drop lines or drag hoses wey dey apply water directly on soil between crops. Crops often dey planted in circle shape to match pivot system. This method dem dey call LEPA (Low Energy Precision Application). Earlier systems dey water-powered, but later dem switch to hydraulic systems and electric motor systems. Modern pivots even dey use GPS for better control.<ref>{{Cite web|url=https://www.agriculture.com/machinery/irrigation-equipment/gps-swing-arms-prove-their-worth|title=GPS Swing Arms Prove Their Worth |last=Gaines|first=Tharran|date=January 7, 2017|website=Successful Farming|access-date=February 1, 2018}}</ref> ==== Irrigation by lateral move (side roll, wheel line, wheel move) ==== For this system, dem dey join pipes together with wheels attached for middle. Each pipe section get wheel about 1.5 m diameter, and sprinklers dey along the pipe. Water dey enter from one end through big hose. After one section don finish irrigation, dem go disconnect hose, drain water from system, then roll am go next position manually or with machine. This system cheaper to install pass center pivot, but e need more human labor because e no dey move automatically. Most times, aluminium pipes of {{convert|100|or|130|mm|in|abbr=on}} diameter dey used. The pipe dey serve both as water channel and axle for wheels.

For this system, dem dey raise underground water level so soil go dey moist from below plant root zone. Some systems dey use canals, pumps, and gates to control water level inside soil through drainage networks. Subirrigation also dey common for greenhouse farming, especially for potted plants. Water dey flow from below, plant dey absorb am, and extra water dey collect for reuse. This system dey save water and nutrients, but e need expensive equipment and careful management.

Low application efficiency mean say water wey dem dey use for farm pass wetin crop or field really need. If efficiency increase, e mean say crop production per unit water go increase. Better efficiency fit come when farmer reduce water for same field or use water more wisely, so dem fit get higher yield for same land area. For some places around the world, farmers dey pay for irrigation water, so over-using water go cause direct money loss for dem. Irrigation too dey need pumping energy (electricity or fuel) to move water go field or maintain pressure, so when efficiency improve, water cost and energy cost per unit production go reduce. If one field use less water, farmer fit use the extra water irrigate bigger area, so total production go increase. Low efficiency usually mean say excess water dey lost through seepage or runoff, which fit also carry nutrients or pesticides go outside farm and affect environment badly. Improving irrigation efficiency normally dey happen in two main ways: either dem improve system design or dem improve irrigation management. System design improvement fit include changing from one irrigation type go another (for example from furrow to drip irrigation) or making small adjustments like flow rate and pressure. Irrigation management dey about how dem schedule watering and decide how much water to apply each time. == Garden irrigation == Domestic gardens and landscaped areas around public buildings dey often get some kind irrigation system especially for dry climates.<ref name=purtill/> For Australia, small garden sprinklers wey dem attach to hose become common irrigation method, and people dey regulate am with sprinkler timer.

If efficiency low, e mean say water wey dem dey apply pass wetting crop need. If efficiency go up, crop go produce more for every unit of water. Dis one fit happen either by using less water for same farm or using water well well so yield increase for same land. For some places, farmers dey pay for irrigation water, so wasting water mean money loss straight. Irrigation also need energy (electricity or fuel) to pump water go farm, so better efficiency dey reduce both water cost and energy cost per production. If one farm reduce water use, farmer fit use remaining water irrigate bigger land and increase total output. But when efficiency low, excess water dey go waste through seepage or runoff, which fit carry nutrients and pesticides go pollute environment. Improving irrigation efficiency dey happen mainly in two ways: improving system design or improving management. System design improvement fit mean change from one irrigation type go another (for example furrow to drip irrigation), or adjust flow rate and pressure. Management improvement mean how farmer dey schedule irrigation and decide how much water to apply. == Garden irrigation == Domestic gardens and landscaped areas around public buildings dey often use irrigation especially for dry climate areas.<ref name=purtill/> For Australia, small garden sprinklers wey dem attach to hose become common, and people dey use timer control am.

A 1918 decree by [[Lenin]] then encouraged irrigation development in the region, which began in the 1930s. When it did, [[Joseph Stalin|Stalin]] and other Soviet leaders prioritized large-scale, ambitious hydraulic projects, especially along the [[Volga]] River. The Soviet irrigation push stemmed mainly from their late 19th-century fears of the American cotton monopoly and subsequent desire to achieve cotton self-sufficiency.<ref>[[#refMcNeill2000|McNeill 2000]] p. 163</ref> They had built up their textile manufacturing industry in the 19th century, requiring increased cotton and irrigation, as the region did not receive enough rainfall to support cotton farming.<ref name="ReferenceC" /> The Russians built dams on the [[Don River|Don]] and [[Kuban River|Kuban]] rivers for irrigation, reducing freshwater flow into the [[Sea of Azov]] and making it much saltier. Depletion and salinization also affected other areas of the Russian irrigation project. In the 1950s, Soviet officials began diverting the [[Syr Darya]] and the [[Amu Darya]], which fed the [[Aral Sea]]. Before diversion, the rivers delivered {{convert|55|km3|cumi|0}} of water to the Aral Sea per year, but after diversion they delivered only {{convert|6|km3|cumi|1}}. Because of reduced inflow, the Aral Sea shrank to less than half its original area, making the regional climate more extreme and creating airborne salinization that reduced nearby crop yields.<ref>[[#refMcNeill2000|McNeill 2000]] pp. 164–165.</ref> By 1975, the USSR used eight times as much water as it had in 1913, mostly for irrigation.
