Water harvesting in dry regions: projects in Kenya

In Kenya, water stewardship is closely tied to food security, rural livelihoods, and the long-term health of agricultural land. Rainfall can be highly seasonal, while extended dry periods place pressure on farms, communities, rivers, and groundwater reserves. Capturing water when it is available helps create a more reliable supply for crops and surrounding ecosystems.

Fresh Del Monte Produce’s sustainability work in Kenya reflects this practical need. Water harvesting, efficient irrigation, soil conservation, and responsible watershed management can work together to reduce demand for freshwater. These measures support agricultural productivity while helping protect the natural resources on which farms and communities depend.

The value of a water project is measured through more than the volume stored. Effective programs also consider water quality, evaporation, recharge, biodiversity, worker safety, and access for neighboring communities. A strong approach connects infrastructure with careful monitoring and everyday decisions in the field.

Why seasonal rainfall requires careful planning

Kenya’s agricultural regions experience substantial variation in rainfall across seasons and locations. A farm may receive intense rain during a short wet period, followed by months when irrigation becomes essential. Without suitable collection and storage systems, much of that rainfall can leave the property as runoff, carrying soil and nutrients with it.

Water harvesting helps convert short periods of abundance into a resource that can support crops during dry conditions. Storage ponds, reservoirs, drainage channels, and collection areas can slow the movement of stormwater and make it available for later use. In some locations, managed infiltration can also help replenish soil moisture and groundwater.

Planning must account for the local landscape. A system designed for a flat plantation will differ from one built on sloping ground, while soil type, catchment size, rainfall intensity, and nearby waterways all affect performance. Regular maintenance is equally important because sediment, vegetation, and damaged channels can reduce storage capacity.

How projects can work across a pineapple farm

Pineapple production requires dependable water management from land preparation through crop establishment and plant development. Rainwater harvesting structures can collect runoff from suitable areas, while lined or managed reservoirs provide a buffer during dry intervals. Where appropriate, water can then be distributed through efficient irrigation systems that deliver moisture close to plant roots.

Field-level measures complement larger infrastructure. Mulching, ground cover, contour practices, and soil organic matter help keep water in the root zone for longer. Good drainage design protects plants from waterlogging during heavy storms and reduces erosion from fast-moving water.

Water recycling can further reduce pressure on freshwater sources. Process water may be treated and reused where regulations, water quality standards, and operational controls permit. The goal is to match water quality with the intended use and to prevent untreated discharge from affecting soils or waterways. Fresh Del Monte’s broader work on plantation water use illustrates how irrigation efficiency and resource conservation can be addressed together.

From collection to measurable conservation

A harvesting project becomes more effective when teams can verify how much water enters, leaves, and remains in the system. Flow meters, rainfall gauges, reservoir measurements, soil-moisture checks, and irrigation records can help identify losses and guide operational decisions. Data also supports early action when water levels fall below seasonal expectations.

Monitoring should extend beyond farm boundaries. Water users need to understand whether conservation measures are protecting downstream flows, wetlands, springs, and community access points. Environmental assessments can help identify sensitive habitats and determine whether a new pond, channel, or abstraction point could create unintended impacts.

The following elements show how individual measures contribute to a wider water stewardship program:

Supporting communities and shared watersheds

Agricultural water systems operate within shared watersheds. Communities may depend on the same rivers, aquifers, and seasonal streams for household needs, livestock, smallholder farming, and other livelihoods. Responsible projects therefore require communication with local stakeholders and attention to equitable access.

Community development can include environmental education, water awareness activities, and partnerships that promote efficient use beyond the farm. Training helps people understand how storage, drainage, and conservation practices affect the wider catchment. It can also encourage early reporting of leaks, pollution risks, or damaged infrastructure.

Water harvesting infrastructure should be developed with safety in mind. Reservoirs and channels need appropriate barriers, signage, inspections, and emergency procedures. Clear responsibilities for maintenance help ensure that an installation remains useful after construction and continues to serve its intended purpose through changing weather conditions.

Protecting land while storing water

The relationship between water and soil is central to dry-region agriculture. Bare or compacted ground allows rain to run off quickly, increasing erosion and reducing infiltration. Vegetated buffer areas, cover crops, carefully managed traffic, and rehabilitation of vulnerable zones can improve the land’s ability to absorb and retain water.

Protected areas and natural habitats also contribute to watershed health. Vegetation slows runoff, supports pollinators and wildlife, and can help stabilize stream banks. Monitoring land near agricultural operations allows conservation teams to identify changes in habitat condition and respond before degradation becomes more difficult to reverse.

Tree planting and landscape restoration can strengthen these efforts when species are selected for local conditions. The right plants can provide shade, improve soil structure, and reduce wind erosion without creating excessive competition for scarce water. Restoration plans should include survival monitoring, maintenance, and replacement where necessary.

Priorities for resilient water management

Long-term progress depends on combining infrastructure with sound governance and consistent field practices. The most useful projects are designed around local climate patterns, reviewed through reliable data, and adjusted when conditions change.

Key priorities include:

• Expand rainwater capture and storage where hydrological studies show a clear benefit.
• Improve irrigation scheduling through soil-moisture data, weather information, and crop requirements.
• Maintain ponds, channels, pumps, and meters so that small defects do not become major losses.
• Protect riparian areas, recharge zones, and other environmentally sensitive parts of the watershed.
• Engage communities and workers in water stewardship, safety, reporting, and conservation education.

These priorities also support responsible sourcing. Suppliers, contractors, and agricultural partners can be encouraged to follow comparable standards for water efficiency, pollution prevention, and ecosystem protection. Shared expectations make it easier to track progress throughout the value chain.

Measuring progress in Kenya

Credible reporting should connect activities with outcomes. It can describe the number and capacity of harvesting structures, reductions in water use, irrigation efficiency, water reused, areas protected, and improvements in monitoring coverage. Qualitative evidence matters as well, including worker training, community engagement, and responses to water-related risks.

Results should be interpreted over time because rainfall varies from year to year. A single wet season may fill reservoirs, while an unusually dry period can reveal weaknesses in storage capacity or distribution systems. Comparing water use with production, rainfall, and environmental indicators gives a more meaningful picture of performance.

For Fresh Del Monte, water stewardship in Kenya can form part of a wider sustainability strategy that links healthy food production with environmental protection and community development. Continued investment in harvesting, efficient use, land conservation, and transparent measurement can help agricultural operations prepare for a less predictable climate.
