Earth Observation Supporting the Assessment of Urban Master Plans in Tanzania

The EO4SD-Urban project supported the World Bank technical assistance project Urban Planning Study – Impact & Effectiveness of Urban Planning on City Spatial Development in Tanzania. The study is linked to the larger World Bank project Tanzania Strategic Cities Project (TSCP), which supports the cities of Tanga, Arusha, Mwanza, Kigoma, Dodoma, Mbeya and Mtwara. These cities are of strategic importance as they are within the top ten most populous cities in Tanzania with high population growth rates. In the context of the current EO4SD-Urban project, all seven cities were provided with mapping products on core urban land use and land cover, peri-urban land cover, urban extent, informal settlements, urban green areas, transport infrastructure and population distribution as well as with additional basic and advanced spatial analytics.

The satellite-based products were used by the bank team to analyse the higher objective of the Urban Planning Study, which is “to enhance the urban development and inform policies and development strategies of cities in Tanzania through gaining further insights on urban planning system and development processes and the effectiveness of master and detailed urban plans.”

Existing urban master plans were compared with the EO4SD-Urban core urban land use and land cover maps and revealed that the seven Tanzanian cities have only a 35 to 45 % land use and land cover conformity to these early master plans. In the peri-urban areas this varies greatly.

The products were produced by the EO4SD-Urban consortium lead GAF AG (Germany) and partners NEO (Netherlands), GISAT (Czech Republic) and DLR (Germany).
