The value of nature in Dar es Salaam
Dar es Salaam has many important natural areas that support the city and its people. Its natural assets range from beaches, rivers, mangroves, coastal and Afromontane forests to wildlife such as birds, bats, monkeys, rich marine life, and coastal plants and animals.
With careful planning, these natural resources can be protected, enhanced and even expanded to sustainably provide many benefits. These include enhanced fresh water provision, food, timber, jobs, cooling of the city, reduced air pollution, protection against natural disasters, opportunities for tourism, recreation and relaxation, and a sense of place.
During the mapping process in Dar es Salaam, city representatives and local experts identified challenges such as dwindling green open spaces, over exploitation of natural resources like indigenous trees and urban heat island effect as key priorities for the city to address.
The natural asset mapping pulled on local knowledge and research and yielded a collection of thematic and explanatory maps that make the case for the importance of green open space in the city and establishing a record which the city can work from to develop policy and practice.
The strength of this approach is that the maps can be overlaid to expose areas where investment in greening can deliver and optimize desired benefits, such as cooling and air pollution reduction.
This approach also highlights potential partnerships. For example, the transport sector implements greening as well as the City Council. The maps identifies areas where these sectors can collaborate and co-invest their greening budgets to optimize urban ecosystem benefits.
A summary document with key maps and information, with policy and action recommendations was developed as a tool that will support they city in making strong arguments for investing in urban nature and nature-based solutions.
The thematic mapping also formed the basis for the development of an illustrated poster of Dar es Salaam that show the natural assets in the city in an attractive and accessible format. The purpose is to create awareness of the presence and value of nature in cities and to inspire officials and the public to protect and benefit from urban nature.
