Climate change increasingly undermines livestock production in Africa’s arid and semi-arid regions, where frequent droughts and erratic rainfall cause severe feed scarcity. Traditional dependence on natural pastures is no longer viable due to shrinking grazing lands and growing livestock numbers. Although crop residues are abundant and locally accessible across these areas, their value as alternative feed sources remains largely untapped. Key limitations include low nutritional quality, poor storage methods, unclear impacts on soil health, and a lack of knowledge on effective processing and integration into farming systems, all of which hinder their use as a reliable feed solution. Addressing this challenge is critical, as improved feed availability directly determines livestock productivity, household income, and food security for millions of smallholder farmers. This opinion article explores the role of crop residues, such as maize stover, rice straw, wheat straw, and legume haulms, as affordable, climate-smart feed resources capable of sustaining livestock during dry seasons. It highlights that proper utilization not only supports animal performance but also reduces environmental pollution from residue burning and contributes to climate change mitigation. The paper outlines proven technologies including urea treatment, ammoniation, chopping, and bio-fermentation that significantly enhance nutrient content and digestibility. It further presents solutions to existing constraints through integrated crop-livestock systems, balanced supplementation, improved storage, and farmer training. Strategic use of crop residues offers a practical, sustainable pathway to strengthen climate resilience, boost livestock yields, and secure food supplies across Africa.
