Cameroon’s government has launched a targeted infrastructure drive to construct five hill dams in the North Region, aiming to expand irrigated area, stabilise water supplies and raise smallholder productivity across dry season cropping zones.

The project focuses on capturing seasonal runoff and storing it for controlled release during the long dry season that constrains cropping cycles for millet, sorghum, maize and irrigated vegetable production. Each dam site has been selected for its catchment potential, proximity to farming communities and ability to support both crop irrigation and livestock watering. Construction will combine earth-fill embankments with spillway and outlet structures sized to the local hydrology to minimise downstream risk.

Economics and local impact Local officials estimate that the dams will enable double-cropping on thousands of hectares previously rain-dependent, increasing incomes for smallholder households and supporting market-oriented production for pet food value chains and urban vegetable markets. The scheme includes community-managed water-user associations to allocate irrigation schedules, collect modest fees for maintenance and coordinate pasture access to prevent overgrazing around reservoirs.

Climate and resilience benefits By shifting production into irrigated systems, the dams are expected to reduce vulnerability to rainfall variability and improve seedbed preparation for higher-yielding crop varieties. The stored water also provides a buffer for livestock during drought spells, reducing herd mortality and the need for costly seasonal migration.

Implementation risks and mitigation Potential downsides include sedimentation reducing storage capacity, unintended displacement of floodplain ecosystems, and the risk of inequitable water allocation favouring larger farms. Project planners propose explicit sediment-management measures, participatory land-use planning, and transparent water allocation bylaws enforced by the water-user associations. Technical assistance and an initial maintenance fund are slated to be part of the rollout to keep infrastructure functional in the first critical years.

Outlook If effectively managed, the five hill dams will serve as demonstration investments showing how relatively small-scale water storage can catalyse year-round production, expand value-chain participation and enhance rural livelihoods while strengthening resilience to an increasingly variable climate.
