Book Description
In large areas of developing countries the loss of trees is causing erosion and degradation of the soil, posing severe problems for economic development. By translating the ecological benefits of afforestation into economic terms, the author demonstrates how investments that benefit the environment often benefit the economy as well. Both the traditional work of the forestry services and tree plantings by farmers are needed, says the author, if deforestation is to be halted and reversed. With special refrence to Africa, he discusses the underlying reasons for deforestation, suggests policy changes to promote the planting and care of trees, and identifies issues for social and scientific research. A case study of the arid zone of northern Nigeria illustrates the benefits that could be brought about by establishing windbreaks and encouraging farmers to plant trees. Besides preventing soil erosion, improving soil fertility, and thus increasing crop prodution, trees provide fruit, livestock fodder, and much-needed fuelwood and building materials. The author compares the increase in farm incomes as a result of an afforestation program with the decrease in incomes if deforestation and soil erosion were to continue. The analysis will be of special interest to those concerned with agriculture, forestry, rural development, and environmental issues in developing countries.
