Author: Saxon Banda Zambia's largely flat terrain presents unique challenges and opportunities for water management, particularly for small and medium-scale farmers. As climate change brings unpredictable weather patterns, such as the upcoming 2024/2025 rainy season, water harvesting becomes crucial to ensure sustainable agricultural productivity. The season is expected to bring episodes of both heavy rainfall and dry spells, making water conservation essential (Zambia Meteorological Department, 2024). Weather Forecast for 2024/2025 According to the Zambia Meteorological Department, the 2024/2025 season is forecast to experience normal to above-normal rainfall in most regions, although the northern parts of the country may see normal to below-normal levels (Parliament of Zambia, 2024). The rains are expected to start in October in some regions and by November in others, with cessation in March and April. Areas such as the north-eastern and north-western provinces are likely to face dry spells, which can disrupt crop growth (Herald, 2024). These variances in rainfall make water harvesting techniques vital for managing water resources during times of scarcity and excess. Weather Forecast for 2025/2026 For the 2025/2026 rainy season in Zambia, predictions suggest that weather patterns will continue to be influenced by climatic variability observed across Southern Africa. According to the Southern Africa Climate Outlook Forum (SARCOF), this period is expected to bring significant rainfall across Zambia, though the timing and distribution may vary due to the lingering effects of past extreme weather events such as El Niño and La Niña. During the previous years, Zambia experienced delayed onset of rains, prolonged dry spells, and erratic rainfall, all of which have exacerbated food insecurity and drought conditions in the region. For the upcoming season, similar challenges, including potential for high rainfall, heatwaves, and dry spells, may affect agricultural output (SADC, 2024). Water Harvesting Techniques for Flat Terrain Given that much of Zambia’s terrain is relatively flat, traditional rainwater harvesting methods such as contour bunds and swales can be used effectively to manage water runoff and reduce erosion. These methods capture water in flat regions by slowing down its movement and allowing for deeper soil penetration, which improves groundwater recharge. Farmers have the opportunity to adopt several water harvesting methods suited to these conditions: 1. Rainwater Harvesting: Simple rainwater collection systems can be installed on rooftops or open fields to collect water in tanks or underground storage facilities. In flat areas, it is easier to create larger surface catchment areas, which can increase the amount of water harvested during heavy rains (Nyambe & Feilberg, 2020). 2. Agroforestry: Integrating trees into agricultural systems is highly beneficial in these regions. Trees provide shade, reduce soil erosion, and improve water retention, especially during heavy rainfall. Nitrogen-fixing trees, like acacias, can also improve soil fertility and provide additional products like fuelwood or fruits. 3. Contour Bunds: Even in relatively flat regions, contour bunding can be employed. Bunds are barriers constructed along the contours of a farm to slow down the flow of water, helping it seep into the ground. This technique is particularly useful in flat terrains to reduce water runoff and improve soil moisture levels (Altieri, 2018) 4. Mulching: Covering the soil with organic material such as straw, leaves, or grass can help retain soil moisture and reduce evaporation. This technique is essential during dry spells, as it conserves water in the soil for longer periods and enhances soil fertility over time. 5. Infiltration Pits and Swales: Shallow channels capture and slowly absorb rainwater. In flat areas, they work efficiently by evenly distributing water across the landscape, preventing waterlogging and ensuring the soil remains moist during dry periods (Mollison, 1988). Farmers can integrate these with crops to maximize both water conservation and soil fertility. 6. Polyculture and Crop Rotation: Growing multiple crops together or rotating them helps maintain soil health, reduce pest infestations, and ensure that different plant root systems utilize water at varying soil depths. Crops like legumes can be intercropped with maize or cassava, improving nitrogen availability and reducing soil erosion. 7. Earth Dams and Ponds: In extremely flat areas, constructing small dams or ponds can be a strategic method to collect and store water. These structures can hold water for irrigation during drier months, ensuring a consistent water supply (Zimba, 2019). Benefits of Water Harvesting Water harvesting is particularly important in light of Zambia’s varying rainfall patterns. With erratic rainfalls expected in the northern and north-eastern regions of the country, smallholder farmers need to prepare for periods of both drought and floods. To adapt to these changing weather patterns, small- and medium-scale farmers in Zambia can benefit from water harvesting and permaculture techniques like mulching, use of cover crops, and agroforestry which improve soil moisture retention and reduce water demand for crops. Effective water harvesting allows farmers to store surplus water during heavy rains for use during dry spells. This helps reduce reliance on rain-fed agriculture and improves resilience against climate-induced crop failures (Herald, 2024). Moreover, by capturing water and preventing runoff, farmers can avoid soil erosion—a common issue in flat landscapes—thus maintaining soil fertility. This is critical for enhancing long-term agricultural productivity (Altieri, 2018). Conclusion As Zambia prepares for the 2024/2025 rainy season, small and medium-scale farmers must implement effective water harvesting techniques, especially in flat regions. With the forecast of variable rainfall, water harvesting practices such as rainwater collection, contour bunding, and swales can help farmers manage water efficiently. These methods will not only ensure a steady supply of water during dry spells but also protect the soil and improve crop yields, ensuring food security and economic stability.
