The market places and their waste management practices in Kinondoni, Dar Es Salaam were mapped using Harava survey tool. The result was a new spatial dataset of the market place locations, as well as useful information on what kind of waste is generated at the market places.
Kinondoni is one of the three main districts in Dar Es Salaam, Tanzania. There are several marketplaces in Kinondoni, some of a formal nature and some of them more informal.
Local authorities have lacked a clear overall picture of the number and location of marketplaces as well as the practices of market place waste management. Previously, information on waste collection has not been reported and reported at all.
Participatory methods will help if the data collection processes are not well-established
The Harava survey mapped the Kinondoni district market locations and their waste management. The data collection was carried out by interviewing the market chairmen and inserting data to Harava using smartphones.
Market place locations were marked on the map. In addition, information on the number of vendors, the quality and quantity of waste produced as well as the method of waste storage was gathered.
A small survey — multiple benefits
- The survey provided a map-based overview of the location and quantities of the market places.
- The survey also collected a whole new kind of information on the waste quantity and processing.
- Participatory methods helped in gathering information that had not been systematically reported before.
- At the same time, an attempt was made to find a model for more regular collection of data.
- Information can be used, for example, in the planning of waste management capacity and other urban infrastructure.
