10 National Irrigation Authority Projects Worth Following in 2026

Kenya's irrigation story is entering a defining chapter. As climate change continues to disrupt rainfall patterns and demand for food grows, irrigation has shifted from being an agricultural intervention to a national economic priority. Across the country, the National Irrigation Authority (NIA) is overseeing projects that promise to reshape farming, strengthen food security and unlock new opportunities for rural communities.

Some projects are expanding long-established irrigation schemes, while others are introducing irrigation to areas where farming has traditionally depended on unpredictable rainfall. Together, they demonstrate how strategic investment in water infrastructure can improve livelihoods, increase agricultural productivity and build resilience against climate shocks.

Here are ten National Irrigation Authority projects that deserve close attention in 2026.

1. Bura Irrigation Development Project

Few irrigation projects carry as much historical and strategic significance as the Bura Irrigation Development Project in Tana River County.

For decades, Bura has stood as one of Kenya's flagship public irrigation schemes. Today, the National Irrigation Authority continues to modernise and expand the project to improve productivity and strengthen food production in one of the country's most important agricultural regions.

According to the Authority, the project covers approximately 15,000 acres and is served by a 53-kilometre main canal, making it one of the largest irrigation developments under its management. The scheme supports crop production while providing employment opportunities and stimulating economic activity throughout the region.

As Kenya seeks to reduce dependence on rain-fed agriculture, the continued revitalisation of Bura will remain one of the country's most closely watched irrigation programmes.

2. Galana Kulalu Irrigation Development Project

No irrigation project has generated more national discussion over the years than the Galana Kulalu Irrigation Development Project in Kilifi County.

Originally conceived as a flagship food security initiative, the project has evolved through different implementation phases. In 2026, it remains one of the National Irrigation Authority's highest-profile investments.

The Authority identifies Galana Kulalu as a 10,000-acre irrigation development currently supporting large-scale maize production while laying the foundation for broader agricultural diversification.

Recent inspection visits by NIA Chief Executive Officer Eng. Charles Muasya, MBS, together with Principal Secretary CPA Ephantus Kimotho, underline the government's continued commitment to ensuring the project delivers tangible results. Officials have emphasised timely implementation, efficient water utilisation and stronger contribution to national food security.

If successfully implemented at scale, Galana Kulalu has the potential to become one of East Africa's most significant irrigation-driven agricultural developments.

3. Mwea Irrigation Development Project

Mention irrigated rice in Kenya and one name immediately comes to mind: Mwea.

Located in Kirinyaga County, the Mwea Irrigation Development Project builds upon one of Kenya's most productive rice-growing regions. The National Irrigation Authority continues to invest in expanding irrigation capacity through infrastructure associated with Thiba Dam, enabling more land to be brought under reliable irrigation.

The project targets approximately 10,000 acres, creating opportunities for increased rice production while improving water management for farmers.

Its importance extends beyond Kirinyaga. Increased rice production contributes directly to reducing Kenya's dependence on imported rice while strengthening household incomes and supporting the country's food security agenda.

4. Lower Kuja Irrigation Development Project

Western Kenya is also witnessing significant irrigation investment through the Lower Kuja Irrigation Development Project in Migori County.

Construction continues on critical infrastructure including a 7.2-kilometre main canal and sedimentation facilities designed to improve water distribution and long-term system efficiency.

The Authority has continued procurement and construction activities during 2026, signalling sustained progress toward expanding irrigated agriculture in the Lower Kuja region.

For many farmers, the project represents an opportunity to diversify production, increase cropping seasons and improve household resilience against changing weather patterns.

5. Expanded National Irrigation Programme

Not every transformative project is concentrated in a single county.

The Expanded National Irrigation Programme reaches across all 47 counties, making it one of the National Irrigation Authority's most ambitious nationwide initiatives.

According to the Authority, the programme targets approximately 127,415 acres while directly benefiting about 70,000 farmers through expansion of irrigation infrastructure and improved access to reliable water for agriculture.

Its nationwide approach reflects a broader shift in Kenya's irrigation strategy. Rather than concentrating investment in a handful of traditional irrigation zones, the programme seeks to extend irrigation opportunities to farmers across diverse ecological regions.

If successfully implemented, the initiative could become one of the most influential drivers of agricultural transformation in Kenya, enabling thousands of farmers to increase production, improve incomes and reduce dependence on increasingly unpredictable rainfall.

6. Gwa Kiong'o Earth Dam Irrigation Project Is Turning Water Storage into Agricultural Opportunity

Some irrigation projects begin with a completely new dam. Others unlock the potential of infrastructure that has existed for decades. The Gwa Kiong'o Earth Dam Irrigation Project in Nyandarua County falls into the latter category.

The National Irrigation Authority is implementing Phase II of the project, which was about 35 percent complete as of July 2026. Once finished, the project will establish irrigation infrastructure capable of serving 500 acres, provide water for approximately 1,000 livestock, and directly benefit around 1,000 households.

What makes the project particularly interesting is its integrated approach. Rather than stopping at water storage, the project is designed to support year-round farming, encourage cultivation of high-value crops and improve household incomes. During a recent inspection, Principal Secretary CPA Ephantus Kimotho emphasized stronger collaboration between national and county governments to maximise the dam's socio-economic benefits. The visit also saw support for aquaculture through the donation of fingerlings, fishing boats and nets, demonstrating how irrigation infrastructure can support multiple livelihoods beyond crop production.

For Nyandarua farmers, Gwa Kiong'o represents far more than another public works project. It offers the possibility of moving away from uncertain rainfall towards predictable agricultural production.

7. Githunguri Cascading Dams Are Bringing Irrigation Closer to Smallholder Farmers

Sharing the spotlight with Gwa Kiong'o is the Githunguri Cascading Dams Phase II Project, another initiative that illustrates how relatively modest investments can have significant local impact.

The project was also approximately 35 percent complete during the July 2026 inspection. Once operational, it is expected to strengthen food security by supporting irrigation, increasing agricultural productivity and enabling farmers to grow higher-value commercial crops.

Earlier public participation exercises revealed additional details. The rehabilitation programme is expected to expand irrigated land by about 53 acres, provide water for 300 livestock, directly benefit around 300 farmers, and generate millions of shillings in additional annual agricultural income. Community members also requested training on irrigation management, value addition and cooperative development, highlighting that successful irrigation depends on knowledge and market access as much as physical infrastructure.

Projects like Githunguri demonstrate the National Irrigation Authority's growing focus on community-centred irrigation development rather than simply constructing infrastructure.

8. Turkana Irrigation Development Could Redefine Farming in Kenya's Arid North

For many years, Turkana has been associated with drought, livestock keeping and humanitarian assistance. Increasingly, however, irrigation is changing that narrative.

The National Irrigation Authority, working alongside the State Department for Irrigation and county stakeholders, is supporting irrigation initiatives intended to unlock Turkana's agricultural potential despite its arid climate. Government leaders have identified irrigation as the key to increasing food production, reducing vulnerability to water scarcity and expanding commercial agriculture across the county.

The significance of these projects extends beyond Turkana itself. Success in one of Kenya's driest regions would demonstrate that irrigation can transform landscapes once considered unsuitable for reliable crop production. It also aligns with the national strategy of reducing dependence on rain-fed agriculture while promoting climate resilience.

9. Community Irrigation Projects Are Quietly Transforming Rural Kenya

Large flagship schemes often dominate headlines, but some of the National Irrigation Authority's most widespread impact comes through smaller community irrigation projects.

Recent procurement programmes show continued investment in projects such as Wamuro Irrigation Development Project in Kiambu, Oldonyiro Irrigation Project in Isiolo, New Kithimu Irrigation Project and Itambua Muthatari Irrigation Project in Embu, Mulwaper Irrigation Project in Elgeyo Marakwet, Kiirua Buuri Irrigation Development Project in Meru, Rukira Irrigation Development Project in Nyeri, Kapkoros Irrigation Development Project in Nandi and several earth dam irrigation projects in Uasin Gishu.

Individually, these projects may not command the same attention as Galana Kulalu or Bura. Collectively, however, they reveal an important shift in Kenya's irrigation strategy. The Authority is extending irrigation infrastructure into many counties, giving more communities access to reliable water and reducing regional disparities in agricultural development.

10. Every Project Supports a Bigger National Vision

Viewed separately, these ten projects appear to solve different local challenges. Together, they tell a much larger story.

The National Irrigation Authority is implementing a national strategy aimed at increasing agricultural productivity, improving food security, creating rural employment and strengthening climate resilience. Whether through mega projects such as Galana Kulalu and Bura or community-focused initiatives in Nyandarua, Embu and Uasin Gishu, each investment contributes to a common objective of making Kenyan agriculture less dependent on unpredictable rainfall.

As climate pressures intensify and demand for food continues to rise, irrigation is becoming one of the country's most important development priorities. The Authority's projects are therefore not simply engineering works. They are long-term investments in economic growth, household incomes and national resilience.

Final Thoughts

The National Irrigation Authority's project portfolio in 2026 reflects a deliberate shift from isolated irrigation schemes to a coordinated national programme with far-reaching economic implications. From revitalising historic schemes such as Bura to expanding rice production in Mwea, unlocking the promise of Galana Kulalu and delivering community-centred projects in counties across Kenya, the Authority is helping redefine how agriculture responds to climate change and growing food demand.

Some projects are still under construction. Others are entering new phases of implementation. Several will take years before their full impact becomes visible. Yet each represents a strategic investment in Kenya's future.

For farmers, these projects promise greater certainty, higher productivity and improved incomes. For the country, they represent an opportunity to strengthen food security, create jobs and build a more resilient agricultural economy. They are worth following not simply because they involve major public investment, but because their success will influence how Kenya farms for decades to come.

Daniel Nzonzo, HSC: The Custodian of Kenya’s Irrigation Story

Image
There are people who build infrastructure, and then there are those who give it meaning. In Kenya’s irrigation sector; where canals cut across landscapes, where dams rise from engineering drawings into living systems, and where water determines whether a season becomes survival or abundance; there is a quieter but equally decisive layer of work that rarely makes headlines. It is the work of interpretation, of translation, of shaping how a nation understands what is being built in its name. At the centre of that layer stands Daniel Mwanzi Nzonzo, HSC , the  Head of Corporate Communication at the National Irrigation Authority (NIA), a man whose professional identity is not defined by loud presence, but by the precision with which he carries Kenya’s irrigation narrative into the public space. To understand his role is to understand something deeper than public relations. It is to understand how modern public infrastructure survives in the mind of a nation; how it is explained, defende...

A New Year Letter to PS Ephantus Kimotho:

Image
  As the new year begins in 2026, I found myself thinking about you. Not just as a Principal Secretary dealing with government systems and paperwork, but as a man deeply focused on water, how it moves, how it is stored, and how it gives life and hope. Most people look at a map of Kenya and see borders and regions. I imagine that when you look at the same map, you see water paths, where it flows freely, where it is blocked, and where the land is still dry and waiting. At the start of this new year, I wanted to write to you directly, to acknowledge the quiet, demanding, and important work you have been carrying over the past few years. The Weight of the Quiet Revolution There is a special kind of pressure that comes with being responsible for a country’s food supply. It is not the loud pressure of politics. It is the quiet, constant knowledge that when a pump fails in Mwea or a canal fills with silt in Turkana , a family somewhere eats a little less. You have carried that responsib...
