This book is the outcome of a two week field-based workshop. The focus is on two villages in the proximity of Khartoum. Several PRA/RRA techniques were used: secondary data analysis; mapping; transects; seasonal calendars; preference ranking; matrix ranking; wealth ranking; venn diagrams and key informant interviews. RRA techniques offer an approach to understanding the complexity of tree management at regional, village, group and individual levels. At regional level the influences on tree management relate to changing patterns of wood product supply and demand and the interaction of urban and rural markets. At village level uncertainty over economic, tenurial and environmental control are key influences governing the management of trees. Preferences for trees by different village groups influence assessments of the costs and benefits of alternative tree management options. Different socio-economic groups have varying and competing interests in the wood economy. The use of RRA enables the development of integrated insights for a more effective understanding of incentives for tree management in Sudan.
