Crown diameter and tree density were measured in 52 communities in the Sudan-Sahel using satellite imagery to determine the relationships between rainfall and distance from community center to crown size diameter and tree density. As distance from the community center increased, tree density and crown diameter decreased. As rainfall increased, tree density decreased while crown diameter increased. Distance from the community center is a proxy for age since urbanization and our results indicate that older parts of communities show longer and more consistent tree management.
These guidelines are the result a consultative process that involved a large number of practitioners from both developed and developing countries. Two meetings were held in Glasgow and Delhi and a tentative outline was agreed upon. The guidelines are intended to provide a reference framework for decision makers and planners to adequately plan, design and manage the forest and trees in and around their cities.

The initial Asia-Pacific Forestry Sector Outlook Study (APFSOS) drew together the myriad forestry dimensions to provide a coherent description and analysis of the situation and prospects for forestry in the region. The study resulted in 50 working papers on a variety of forestry themes. The formal aspects of the study culminated in a comprehensive main report, published in November 1998. APFSOS provided an important roadmap for forestry sector development in the Asia-Pacific region to 2010, which is still being used to guide policy makers in the region today.
FAO has initiated a series of global and regional sector outlook studies to examine linkages between forests and societies and to indicate emerging opportunities and challenges. The Forestry Outlook Study for West and Central Asia (FOWECA) has considered these issues through an extended consultative process in 23 different national contexts in West and Central Asia.
This issue of Unasylva analyses the urban forestry situation and considers its potential for increasing living standards in different urban settings.
