Geographic and Economic Overview.

Thiba is located within Mwea Constituency, Kirinyaga County, a region predominantly known for its expansive irrigation scheme. The Mwea Irrigation Settlement Scheme (MIS) spans 30,350 acres across Mwea East and Mwea West sub-counties, with development dating back to 1954 when it began with just 65 acres in the Tebere section. Today, the scheme has expanded to become Kenya’s largest irrigation project, accounting for approximately 80% of the country’s rice production.

The economic significance of the region cannot be overstated. Before recent infrastructure developments, the 25,000 acres under cultivation produced around 114,000 metric tonnes of rice with an economic value of KSh10 billion annually. The area’s economy is heavily dependent on agriculture, with rice farming being the primary economic activity supporting thousands of livelihoods.

The Transformative Thiba Dam Project.

The most significant recent infrastructure development in the region is the completion of the Thiba Dam, a transformative project that has revolutionized agricultural production in Mwea. Constructed at a cost of approximately US $68 million (about KSh20 billion), the dam was co-financed by the Kenyan government and the Japanese government through the Japan International Co-operation Agency (JICA).

Technical Specifications and Timeline.

The Thiba Dam stands as a monumental engineering achievement with impressive specifications:

Height: 40 meters
Length: 1 kilometer
Water capacity: 15.6 million cubic meters, including dead storage of four million cubic meters
Construction period: March 2018 to May 2022

The dam is equipped with a spillway to prevent flooding during rainy seasons and water intakes that convey water to irrigation systems. In April 2025, however, flooding occurred when the Thiba River burst its banks following heavy rains, displacing over 700 people from three villages in Mwea, highlighting ongoing challenges in water management despite the new infrastructure.

Agricultural Impact.

The completion of the Thiba Dam has had a profound impact on agricultural productivity in the region:

Expanded Irrigation Area: The dam has increased the irrigated area from 25,000 acres to 30,600 acres, opening up an additional 5,000+ acres for rice cultivation.
Multiple Cropping Seasons: Before the dam, farmers could typically grow rice only once or twice a year. The dam now allows for three growing seasons annually, significantly increasing yield potential.
Doubled Production: Rice production has increased from approximately 114,000 metric tonnes to about 220,000 metric tonnes annually, nearly doubling output.
Economic Value Enhancement: The annual value of rice produced in the region is projected to increase from KSh10 billion to KSh18 billion, representing an 80% increase in economic value.
Household Impact: The dam provides irrigation water to approximately 5,000 households, significantly improving livelihoods and food security in the region.
