Effects of Deforestation

Chapter 1 presented the values of forests in terms of timber resources and fuelwood. It also referred to non-timber tropical forest products such as pharmaceuticals, fibers such as rattans, and foods such as Brazil nuts. Also discussed were non-market values of tropical forests such as preservation of biodiversity, regulation of climate, carbon sinks, indigenous cultural knowledge, and esthetics. All of these values are affected as a result of deforestation. Chapter 2 showed how deforestation results in the loss of productive potential of the soil, as a result of nutrient loss following destruction of the nutrient-conserving mechanisms of the intact forest. Here, we present case studies of the impact of deforestation on the environment, and on the people that live in and around tropical forests.
