In the heart of Lalo, Benin, a pressing challenge looms large as the dry season approaches. Farmers in this region are grappling with the dual demands of agricultural water needs and domestic consumption. As water resources dwindle, the quest for sustainable solutions becomes not just a necessity but a lifeline for local communities. This is where the recent research led by Djigbo Félicien Badou from the Laboratory of Plant Sciences, Horticulture, and Forestry, at the National University of Agriculture, steps in, offering a glimmer of hope for both farmers and households.
Badou’s team undertook a comprehensive evaluation at the Tovinou site, delving into borehole productivity and irrigation water availability. Their findings reveal a well-thought-out irrigation plan that allocates 24% of the area to drip irrigation and 76% to micro-sprinkler systems. This strategic distribution allows for efficient water use, crucial during the peak demand months of January when the need can skyrocket to 5639.2 m3. “By operating the borehole at 85% of its flow capacity, we can meet both agricultural and domestic water needs effectively,” Badou explains, highlighting the balancing act that is essential for sustainable water management.
The research underscores the importance of rotational watering, a method that ensures crops receive adequate hydration while still catering to the water needs of local households. Depending on the growth stage and season, irrigation durations can vary significantly, with drip irrigation running for 46 to 152 minutes and micro-sprinkler systems for 37 to 440 minutes. This flexibility not only maximizes water efficiency but also supports off-season vegetable production, which can be a game-changer for local farmers looking to boost their income.
The implications of this study are far-reaching. With the framework proposed by Badou and his colleagues, there’s potential not just for increasing agricultural output but also for fostering resilience in rural communities facing water scarcity. “We’re not just looking at numbers; we’re looking at livelihoods,” Badou emphasizes, pointing to the broader commercial impacts of their findings. By ensuring a reliable water supply for off-season crops, farmers can tap into lucrative markets, enhancing food security while also contributing to local economies.
As water demand continues to rise across rural West Africa, the insights from this research published in *Agricultural Water Management* (the English translation being *Agricultural Water Management*) could very well shape the future of irrigation practices in the region. It’s a compelling reminder that with the right strategies, it’s possible to harmonize agricultural needs with domestic water supplies, paving the way for a more sustainable and prosperous future. The balance struck here could serve as a model for similar challenges faced in other parts of the world, making this study not just relevant locally but globally significant as well.
