Forests have been called the lungs of the world, providing oxygen essential for life. Forests also provide a livelihood for nearly 500 million people across the globe. Clearly, they represent an important resource for all. However, an accelerated rate of destruction of primary forests, especially in the 1980s, caused concern as this great resource was threatened. The Bank's World Development Report 1992 estimated that 17 million to 20 million hectares of forests are being lost every year, mainly in developing countries. This is clearly not a sustainable level of use.

To address the very real needs for protection and conservation of forests and the need for development, the World Bank has taken a lead in pioneering efforts at sustainable development, with attention to forestry concerns. The Bank seeks to address two key forestry challenges: to slow the alarmingly rapid rates of deforestation, and to ensure adequate planting of new trees to meet the rapidly growing world demand for wood.

This technical paper helps address the latter challenge. In addressing technical issues of growing media for tree seedlings, the Bank is working with others to achieve the much larger goal of adequate planting of new trees of superior quality. This paper outlines processes for making nursery operations more efficient, benefiting nursery and plantation managers, whatever their scale of operations. We hope this paper will bring those working for goals similar to ours one step closer to achieving sustainable development.
