Land degradation being an aspect of desertification is one of the challenging environmental problems which depends on the process of a mathematical modelling. To tackle this formidable environmental science problem, we have developed a sound database system that is driven by a computationally efficient numerical scheme to clearly show that the loss of land’s biological and economic productivityand complexity as defined by UNCCD [1] is more vulnerable to depletion ranging from the average value vulnerability of depletion of 7.95 approximately to 0.6 approximately. As a response to decreasing the natural growth rate of land use from0.6 to 0.006 provided the initial consumption units of land use ranges from its value of 100 to 1500. On the basis of this quantification, when the notion of the human population modelling is considered, the results of this present analysis clearly show that the smaller the initial consumption of land use, the more vulnerable land degradation can occur whereas the bigger the initial consumption of land use is associated with a weak vulnerability to degradation which is clearly smaller than the average vulnerability to depletion. These detailed results that we have obtained showed clear sustainable development implication which has not been seen elsewhere; these are carefully presented and discussed quantitatively
