what is meant by the termchanging resource use

Many different factors work together to limit or alter the way forest resources are used. Widespread forest degradation caused by expanding agricultural land clearing, conversion to plantations (cocoa and timber), and timber exploitation all diminish people’s access to forest products. In addition, migration from rural areas to urban centers has created larger markets for some forest products. Increased commercialisation of rural economies in conjunction with increasing populations and degradation of the forest resource base have served to increase the pressure on dwindling resources.
