Solar irrigation system: Analysis of the solution for livestock production in North Cameroon

This article examines the impact of implementing a solar irrigation system on livestock production in North Cameroon, a region marked by climatic challenges and increasingly dry conditions with 600 to 1,200 mm of rainfall per year and temperatures between 30°C and 40°C. Livestock farmers in the region rely heavily on natural pastures and forage crops to feed their livestock, but these resources are insufficient during periods of drought. The area is home to around 2 million head of cattle, with an estimated 500,000 to 700,000 head of sheep and 300,000 to 500,000 head of goats. Our methodology involved a comparative before-and-after analysis, where data on crop yields, pasture quality and animal performance were collected. Statistical simulation was used to assess improvements in pasture biomass, forage yield and animal performance. The results show significant improvements if the solar irrigation system is installed, with: a 30% increase in biomass; a 50% increase in forage yield with a 16.7% gain in animal weight; a 20% increase in milk production; a 30% reduction in forage procurement costs; and a 33.3% increase in income generated. These results indicate that solar irrigation will have a positive impact on farm productivity and profitability. The installation of a solar irrigation system in Northern Cameroon represents a sustainable and economically viable solution for improving livestock production in a region vulnerable to drought.In sub-Saharan Africa, solar irrigation systems have been successfully implemented in several countries, including Kenya, Ethiopia, Mali and Burkina Faso. These projects have demonstrated the viability of this technology in semi-arid and arid environments, with notable improvements in agricultural production and water management. The climatic and geographical conditions in Northern Cameroon are similar to those in the regions where solar irrigation systems have been tested.
