Abstract
Despite its nutritional potential, Tiger nut remains under-utilized. This study examined the interactive effects of soaking time (24–72\,h) and microwave power (100–280\,W) on its proximate composition using response surface methodology. Commercial tubers (14.33% moisture) were rehydrated to 38.6–46.8% moisture via soaking and then microwave-dried at 2.45\,GHz. Proximate composition was determined by AOAC methods. Ash, fat and carbohydrate followed linear models (\(p<0.0001\)); fiber followed a two-factor interaction model (\(p<0.0001\)); protein showed quadratic behavior (\(p=0.0006\)). Multi-response optimization identified 48\,h soaking and 190\,W power as optimal (desirability=0.87... More >

Abstract
The ongoing conflict between herdsmen and farmers across different regions in Nigeria over scarce natural resources continues to generate disputes that threaten the lives and property of citizens. The impact of this crisis is now escalating to a level that significantly endangers the country's socio-economic development and overall security. It is essential to explore technological solutions that can sustain both herdsmen and farmers in their respective activities while making the best use of limited land resources. This study investigates the potential of agrivoltaics as a strategy to address Nigeria's nomadic cattle rearing challenges. A review of existing literature was conducted on the s... More >
