Research reported here has been conducted to measure Prosopis juliflora for its invasion and growth potential, altitude and habitat preference, desert greening and amelioration of the global climate change complex. Results from global literature review were integrated with field survey data within the Ethiopian great rift valley. ANOVA results confirmed significance of altitude over habitat (P = 0.01) for seed production, and significance of habitat and altitude (P = 0.05) for wood production preference of Prosopis juliflora. Linear correlations provided evidence of low altitude preference of Prosopis juliflora for seed production which is negatively correlated with altitude (r = - 0.711; r2 = 51%). Low altitude preference of Prosopis juliflora for wood production is negatively correlated with altitude (r = - 0.399; r2 = 16%). Multivariate principal component analyses showed that low altitude with dry river is the principal component contributing maximum share for seed and wood production of Prosopis juliflora. Therefore, dry rivers of low altitudes are the best interactions for Prosopis juliflora seed production, invasion potential, wood production, growth potential, desert greening, resolving global climate change complex, reversing ecosystem degradations, enriching deserts and sustaining biodiversity.
