Impact of human activities on forest resources and wildlife population

Abstract

Nowadays, management and regulation of natural resources like agriculture, fisheries, forestry and wildlife is one of the popular topics in research. The evolution of humankind is largely dependent on the quality of the environment and the resources it provides; but numerous human-induced factors, and climate change may drastically change the conditions of human sustainability. A wide range of human activities on forestland contribute to climatic change, prominent among these are, deforestation, desertification, industrialization, urbanization and other socio-economic activities. In this paper, attempts have been made to trace the causes and consequences of these human activities on the depletion of forestry resources. A nonlinear mathematical model is proposed and analyzed. In modeling process, we assume that the growth rate of wildlife population wholly depend on forestry biomass. It is depleted by human activities. Local and global stability analysis of the mathematical model along with the persistence of the system is checked using theory of nonlinear ordinary differential equations. Analytical results obtained are justified numerically through numerical simulation. Important parameters are investigated and variation of variables with change in these parameters is determined.
