Nigeria, particularly the North, could face severe water stress in the coming months. Also, severe droughts coupled with dilapidated dams have created food insecurity with lower crop yields due to irrigation problems. Stakeholders are worried that reduced water flows will impact the economies of the region, driving up prices and causing increased hunger. They are calling for immediate rehabilitation of several dams and implementation of climate-friendly innovative irrigation solutions to address drought and improve water use efficiency. DANIEL ESSIET reports.
States in the North are facing a climate change challenge and increasing pressure on water resources for agriculture. This has had a direct impact on food production with a growing need for irrigated crop production.
While initial concerns focused mostly on lack of irrigation water, there is the impact of the flooding.
Indeed, the breakdown of dams and the drying up of the irrigation canals have led to additional concerns over agricultural production and export shortages.
Co-founder/Chief Executive, Farmer First Technologies, Gyena Iliya noted that dams play a major role in ensuring food security.
According to him, while food systems have been an important driver of future dam construction, maintaining it has so far been overlooked.
He highlighted the need for adequate water supply to support irrigation, adding that better management of reservoirs has become a priority.
Iliya has been associated with farmers in the North who have had to confront regular forecast of long-term drought, warning of high temperatures, crop damage and water supply shortages. While rains have been below average across the region, the strain on water reserves has been exacerbated by increased domestic demand.
His words: “Farmers within the Northwest and Northeast region experience lack of water supply and it affects productive in agriculture, especially crops production. Because of this, Sokoto, Zamfara, Kano, Yobe and Borno are working with farmers’ network from other states.
According to reports, the federal system of dams’ accounts for the bulk of the water farmers uses to irrigate more than 600,000 acres. As part of efforts towards proper harnessing of surface and groundwater, the Federal Government, through the Ministry of Water Resources, has over the years constructed 260 dams and impounded 34 billion centimetres of bulk water in dam reservoirs for multi-purpose use, including water supply, sanitation, irrigation and power generation.
However, receiving less of the water has been troublesome in the North as overall water use has gone down even as the number of farmers has risen.

With pressure on water resources a major challenge in the North, initiatives to reduce water loss through agricultural irrigation is seen as key in addressing water scarcity, according to the co-founder, Corporate Farmers International, Akinwale Alabi, who is seeking innovations in irrigation that would have a positive impact on the future of sustainable agriculture.
In an interview with The Nation, he explained that broken dams and depleted reservoirs have leave critical production areas in the North without a key water supply.
His words: “First, the responsibility for the maintenance of the banks rest on the state governments. I am going to take Jigawa as an example. If you look at what the governor is doing by ensuring that dams that are accessed by farmers in the state have right of way. He is constructing a very big dam to assist their small holder farmers. When dams broke down, cultivation of crops such rice, onion and grains are affected. Once an administration identifies specific dams that are damaged, they should put in place measures to repair them. This is to ensure it does not affect other farmers.
“Secondly, the Federal Government also has a role to play.There is a department in the Federal Ministry of Agriculture and Rural Development, which monitors specific dams and irrigation projects round the country.This helps for dry season farming. Once they have red alert on a specific dam, they should move to action.The ministry has to buckle up to ensure that dams that can be used for dry season farming are in good condition.The government should work on dams that are broken or damaged. We have to give kudos to the Jigawa State government that is doing a lot in proper dam maintenance.
“What happened in Niger State last year was excessive rainfall and dam damage. Dam damage is a major risk. States such as Niger, and Nasarawa with issues on dam access have to buckle up.This is the rainy season and we might experience concurrent rain that might led to excessive floods and crop destruction. They have to ensure they water control to avoid loss of farm produce.”
Alabi said Jigawa State has done a lot to improve water supply for farmers through irrigation.
He is worried about the future of the farms as climate change threatens the viability of rice farming.
Lead Strategist, FutuX Agri-consult Limited, Olarewaju Babatunde is among stakeholders calling for a mega irrigation to protect the region from drought.
He observed that rice farmers are threatened by the number of dams breaking down. This has had a severe impact on food security.
An agronomist with the Flour Milling Association of Nigeria (FMAN), Ahamed Tijani, has seen situation where farmers struggled to irrigate their crops because the dams have broken down, thereby affecting the flow of water to their fields. Though several dams have been rehabilitated and improved across the region, he called for increased government’s action to support construction of small multi-purpose dams.
He recalled the hardship farmers in some parts of the North had been facing, as a result of lack of water for irrigation.
With collapsed dams, Tijani explained that farmers would be unable to engage in dry season farming and fishing.
According to him, a lot of communities depend on dams for survival during the dry season – for farming and fishing.
Tijani expressed concern that the non-functionality of some dams could aid the expected harsh dry season to spoil some highly water- consuming crops.
Farmers in some parts of Kaduna State have seen enough rains, particularly in the past few years, amid climate change that is exacerbating extreme weather patterns.
Tijani has seen farmers trying to grow water-hungry cucumbers and peppers on land but the available water wasn’t sufficient for traditional irrigation. There were cases where a few farmers tried a drip irrigation system, supported by a government initiative.The system delivered small amounts of water, where seasonal rains are no longer a reliable source of water.
His concern is that not much has been done to help small-scale farmers adopt water-efficient irrigation.
Except for states such as Sokoto and Kano, according to him, there have not been remarkable plans to help farmers enjoy an abundance of water.
He said there were situations where farmers either did not get rain when they needed it or got too much rain when their crops needed dry conditions.
Unless mitigating measures to address the water supply problem are implemented, Tijani sees it affecting food production.
He said the occurrence of the drought or prolonged dry spell and the delay in the implementation of irrigation systems are among the reasons water supply for agriculture keeps on decreasing.
Deputy Managing Director, Incubation,OCP Africa, Caleb Usoh said the government must also invest in the construction of more dams, not only for irrigation but also as a reserve reservoir for water supply of urban areas during droughts.
Despite the Federal Government’s renewed commitment to revolutionalise the agricultural sector, 96 per cent of the dams are dysfunctional, experts said. The purpose of the construction of dams was to boost water supply, provide reservoirs for flood control, irrigation farming and hydroelectricity.
According to analysts, water is hardly reaching the farms, as most of the dams have been neglected by governments.
Recently, the President, Nigeria Agribusiness Group (NABG) Emmanuel Ijewere lamented that of the 264 dams in the country, only five are functional.
He stressed that getting the dams to work would boost productivity and attain self-sufficiency in crop production.
The country has irrigation land potential of about 3.1 million hectares, out of which only 150,000 hectares have been developed, according to the Federal Ministry of Water Resources.
National President, All Farmers Association of Nigeria (AFAN), Ibrahim Kabiru, said: “Most of our dams are underutilised and some are just abandoned, especially those built by various local governments.
“Farmers must start farming all-year round to meet the rising demand for food and it is only through irrigation we can do this.’’
The NABG vice president noted that this depended on the functionality of the dams.
He noted that without the revitalisation of dams, the government would not achieve its goal of diversification through agriculture.
The major challenge is that some of the dams were not built for irrigation, experts said.
Last year, the Federal Government announced the completion of 10 dams and four irrigation projects across 10 states. It said six irrigation projects were ongoing in five states, adding that the facilities were being developed to boost agriculture and support the nation’s quest for food security.
According to the ministry, Nigeria has a total of 250 medium and large-sized dams with a combined storage capacity of about 30 billion cubic meters.
“The total storage capacity of these dams is more than the projected future demand of Nigeria by 2030,” the ministry added.
The completed dams, according to the ministry, include Kashimbila Multipurpose Dam, 500,000 cubic meters, in Taraba; Ogwashi-Uku Multipurpose Dam, 4mcm, in Delta; and Adada Dam, 1.4mcm, in Enugu.Others are Sulma Earth Dam, 4mcm; Gimi Earth Dam, 4.5mcm; Kampe Omi Dam, 250mcm; and Amla-Otukpo Dam, 1.5mcm; located in Katsina; Kaduna; Kogi and Benue states.
Others are Amauzari Earth Dam, 25mcm, in Imo; Ibiono-Ibom Earth Dam, 0.3mcm, in Akwa-Ibom; and Kargo Dam, 2.3mcm, in Kaduna. On irrigation projects, the report said four of them had been completed, while six others were ongoing. It said irrigation projects in Ejule-Ejebe, 50 hectares, Kogi; Azara-Jere, 1,880ha, Kaduna; Sabke, 879ha, Katsina; and Sepeteri, 280ha, Oyo.
The ongoing irrigation schemes include Bakalori, 13,557ha, Zamfara; Hadeja Valley, 6,000ha, Jigawa; and Kano River, 15,000ha, Kano, Dadin Kowa, 2,000ha; Middle Rima, 4,333ha; and Gari, 2,114ha irrigation schemes situated in Gombe; Sokoto and Kano/Jigawa states.
The water ministry noted that the aim of the Federal Government’s irrigation programme.
Morocco
A July World Bank report on the Moroccan economy stated that the decrease in the availability of renewable water resources put the country in a situation of “structural water stress”.
The Interior Ministry ordered local authorities to restrict supplies when necessary and prohibits using drinking water to irrigate green spaces and golf courses.
Illegal withdrawals from wells, springs or waterways were prohibited.
In the longer-term, the government plans to build 20 seawater desalination plants by 2030, which should cover a large part of the country’s needs.
Last year, African Development Bank Group (AfDB) strengthens its technical assistance to boost water resources in Morocco. The bank approved a Technical Assistance for Dam Design and Interconnection Studies on the water facilities in Khenifra located in the Middle Atlas, in central Morocco.
A 201,000 Euro grant, extended through the Bank’s Technical Assistance Fund for Middle-Income Countries, support technical assistance to the Government of Morocco for the design of dams, river development and inter-basin interconnection studies. The beneficiary institution is the Directorate of Hydraulic Development of the Ministry of Equipment and Water.
University of Manchester study on Africa’s Irrigation
A new research, published in Nature, by a University of Manchester-led consortium quantified the performance of 79 African irrigation schemes.
According to the study, big irrigation projects in Africa have failed to deliver.
The team argued that it is the political and management frameworks underpinning African irrigation development leading to the underperformance.
While failures of large-scale irrigation in sub-Saharan Africa have been acknowledged, it continued that its research suggested that this has had little impact on the way planners or governments approach such projects.
According to the study, investments in large-scale water infrastructure will continue to an important means of agricultural production.
It called for investments in storage infrastructure – both built and natural – to ensure reliable access to water. This, it noted, will provide a basis for encouraging farmers to invest in irrigated agriculture, thus reducing risks associated with adoption of new technologies or practices.
