Urbanization and climate change will define much of the 21st century. Urbanization leads to improvement in standards of living, and through the increased density and service delivery efficiency of cities, higher growth can be achieved with lower greenhouse gas emissions. Cities and urban agglomerations house more than 50 percent of the global population and contribute more than 70 percent of Global greenhouse (GHG) emissions. As the share of urban population grows, sustainable urban development emerges as an essential component in addressing climate change.
The planning and management of urban forest has become increasingly important as a focus of urban environmental management. The objectives of this study were to analyze the landuse/land cover and to map functional zones of the urban forest in the upper catchment area of Addis Ababa. This study identifies five landuse/land cover types: (i) Eucalyptus–Juniperus dominated forest, (ii) mixed native forest, (iii) built-up areas, (iv) Eucalyptus plantation (v) crop/grazing lands.

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.
