Legibility of Small-Scale Industrial Sector in Promoting Social-Economic Development of Informal Settlements: Case of Mlalakuwa in Kinondoni, Dar es Salaam

Small-scale industries constitute essential elements in accelerating the flourishing of the economy in towns. Cities in global south countries are witnessing an expansion to an unprecedented scale. The growth of cities is accompa-nied by the emerging of small-scale industrial activities like handcraft indus-try, car repair workshops, sewing, furniture making, which act as economic pivots for urban proliferation. They represent an important factor for the provision of employment to a large number of people living in urban centres. The investigation was done through a case study of small-scale industrial activities running at informal settlements to provide a better understanding of the roles of small-scale industries that promote community quality of lives at Mlalakuwa informal settlements. This paper aims at providing an understanding of the diversity of small-scale industrial sectors as a potential tool for the development of collective spaces usage at Mlalakuwa informal settlement. Small-scale industrial activities are well known in informal areas in the city of Dar es Salaam because they provide opportunities for boosting local social-economic activities and improving the community’s livelihoods. The results show that more than 50% of the residents engaged with small-scale industries to sustain their daily lives. Whereby 70% of the settlement growth development at Mlalakuwa is the result of small-scale industrial activities. There has been a good opportunity for the authorities to have an integrated revenue collection between formal and informal economic sources if SSI activities will be positively considered one of the economic


Introduction
Small-scale industries are sub-sectors of the business sector, which play an important role in improving the national GDP (Ahmed, 2006;UNEP, 2016). Restructuring of the economic sector in the developing countries is the result of switching out from the agricultural sector to the industrial mode of production (IBID). It is argued that cities in sub-Saharan Africa urbanization have been decoupled from economic growth due to improper strategic plan of national policies and less effort done in planning practices (Pacione, 2001;Henderson, 2002). Sub-Saharan Africa has the highest percentage of the working poor who depend on small-scale industrial sectors as a major source of income generation (Dixon et al., 2001;ILO, 2005a).
Nigeria had economic structural challenges in the 1980s as a result of the global recession, including foreign exchange scarcity, unemployment, inflation, mounting governmental debts, low productivity, and general social problem (Aikoye, 1989;Francis, 2009;Obi, 2015). In 1982, the federal government enacted the economic stabilization act with the intention of restructuring the economy (IBID). In an attempt to reduce poverty, therefore, initiatives from various individuals and small-scale industrial activity groups were established (Kigbu & Maku, 2015). The existing regulations and planning methods aimed at small-scale industries have a detrimental impact on how efficiency is practiced in informal settlements (McGranahan & Brown, 2015;Wijaya et al., 2019). On the other hand, the city's planning is rarely considered SSI 1 operating in informal settlements while their existence gives positive results in taxes and levies collection in many cities in the country.
The aspiration of low-income communities is to overcome the financial challenges that are not fulfilled by authorities by building up strong collective assets which will help to construct better economic infrastructures to sustain their lives in urban environments (Ogundiji, 2006;Onibokun et al., 1987). This gives an opportunity for informal residents to establish various types of SSI to overcome the social and economic barriers erected by development actors in the sense of transforming informal settlements (Schmidt-Traub, 2015;Shand et al., 2017).
Many scholars accentuate that countries in the global south countries need substantial investments to solve the social, economic, and environmental challenges that informal dwellers face in urban centers (ILO, 2005b;Magalhaes & Eduardo, 2007). Communities who are living in extreme environmental conditions are trying their best to catch up with the environment in many ways to fill the gaps left be-tween formal and informal development (Chakrabarti, 2001;Edusah, 2013).
The population growth in many cities in developing countries is driving up demand for land to establish new housing and economic infrastructures. As many authorities are often shown unwilling to provide economic infrastructures in informal settlements due to insufficient development budget from the central government (Amiri & Lukumwena, 2018;Jahani, 2020). This demonstrates the loss of management strategies of many authorities have resulted in many informal residents having alternative solutions fighting against poverty reduction (King & Dovey, 2013;UN-Habitat, 2016). The inability of formal sectors in Ghana pushed low-income communities into SSI sectors which operated in many informal settlements that were found to be leftover from the city's development process (Osei-Boateng & Ampratwum, 2011).
Before the 1990s, Tanzania was among the African developing countries with vibrant industries operated under Small Industries Development Organization 2 (Mtatifikolo, 1998;Mwang'onda et al., 2018). Due to unstable economic sectors and political changes, all mills went down (Skarstein & Wangwe, 1986). The privatization policy gave out negative results that led to rapid city urbanization and an increased amalgam of small-scale industries to meet the demand for employment opportunities in the country (Moshi, 2001;Marwa, 2015). However, the urbanization trend is the result of informal settlements and the booming of informal industrial sectors in many developing cities (Allen, 1977;Huchzermeyer, 2004). The informal settlement became an economic hub for low-income communities to drive their social-economic activities for their daily lives (Amiri & Ghanbari, 2016).
Within the informal settlements, there is some space that needs to be understood their existence, importance and how they contribute to the operation of small-scale industrial activities (Avermaete et al., 2006). Scholars often depict the importance of public space, common space describing their contribution to the liveliness of that space (Lupala, 2002;Nguluma, 2003;. Manuel De sola Morales contrived the term collective space where community get accessibility for social, economic and political issues (de Sola Morales, 1992;Schoonjans & Zhang, 2020). Scheerlinck (2013) depicted collective space as a point of intersection for the community to share common values (Scheerlinck, 2013). This can be also linked to informal settlements as well where collective spaces seem to be an important space for various activities including the operation of Small-Scale industries.
Today the growing small-scale industrial activities in informal settlements areas are witnessing taking place in unpredictable ways (Gaillard & Beernink, 2001). The economic sectors have not grown enough to accommodate a number of people in cities including Dar es Salaam (Sheuya, 1997;Bernstein, 1982;Diochon, 2003). The small-scale industrial sector has become an immediate tool to assist informal settlements communities to solve unemployment challenges that happen to exist for many decades (Sheuya, 1997). However, little has been paid at-tention to the operation of small-scale industrial sectors in informal settlements. In this manner, there is a need to investigate the legibility of small-scale industrial activities in informal settlements, and the extent to which economic activity clusters add values to collective space in the flourishing of the urban economy. This paper aims to analyze the types of small-scale industries and their locations, as well as to examine their potential modes of operations, including all systems of the supply chain that enhance the spatial development of collective space at Mlalakuwa informal settlements.

Methods
The study employed qualitative methods such as interview methods and focused group discussion in gathering data to obtain an understanding of the present conditions. Primary data was gathered through a focused group discussion held with Mlalakuwa residents, who engaging with SSI activities at Mlalakuwa informal settlement from April to August 2021. Interviews were also held with six groups of Small-Scale Industries at different locations. Then latter were sampled through snow ball method while the former given the nature of their activities were accidentally or conveniently sampled. Sampling was necessary to this research as (Selltiz et al., 1977) opined: (…) "It is rarely necessary to study all the people in a group in order to provide an accurate and reliable description of the attitudes and behaviour of its members. More often than not, a sample of the population to be studied is sufficient" (Selltiz et al., 1977).
The researchers sampled the SSI in a purposive manner by identifying 52 respondents with four different user groups that were interviewed. The focus was on SSI located at Mlalakuwa informal settlements which were established by individuals or small groups to examine how they battle in exploring the spaces for the purpose of establishing the SSI activities. The choice was also based on individual person who could start with a very confined space with a little capital and started to grow up time after time. The primary data was supplemented by secondary data sources such as articles, surveys and other studies conducted on the emerging of economic infrastructure which led to spatial growth at Mlalakuwa informal settlements.

Case Study
The research case study is Mlalakuwa informal settlement located in Kinondoni district, Dar es Salaam region. Mlalakuwa is one of the prominent informal neighbourhoods which is surrounded by six major activity centers, namely: Mwenge military hospital, Mwenge woodcarvers market, DDC Mlimani park 3 , a retail center (Mlimani City Mall), University of Dar es Salaam, and Ardhi University. Mlalakuwa is an informal settlement with a diverse social and economic population, including students, faculty and non-academic staff, vendors, landlords, nurses, and retired army officers Lutta et al., 2021).
The pressure to search for collective spaces for various economic and social activities is increasing every day to mitigate the number of inhabitants and non-inhabitants looking for services. According to URT (2013), Mlalakuwa has a population of about 19,453 inhabitants, of which 9950 are men and 9503 are women.
Nevertheless, it is a settlement that keeps on receiving new people with the aspiration of connecting the community to social, economic, and physical development potential (Teyanga & Mrema, 2018;Tesha, 2020).
Mlalakuwa is located in the western part of Dar es Salaam city and is well connected to other parts of the city through Sam Nujoma Road, Morogoro and Bagamoyo highways (Figure 1). The current challenges at Mlalakuwa, as in other informal settlements, include the operation of SSI, which leads to an emerging diversity of collective spaces such as car repair workshops, furniture workshops, steel workshops, and sewing workshops. This is the concern to study how the informal settlement is legible to attract the operation of SSI activities which led to the development of Mlalakuwa neighbourhood.

Analysis of the Legibility of Small-Scale Industries
There are 6 main types of Small-Scale Industries, which make a total of 56 Small-Scale Industries found in the Mlalakuwa area this is includes: 8 car repair garages, 11 sewing workshops, 22 wood processing and furniture workshops, 2 bakeries and 11 steel workshops and 2 Cement and sand blocks (Table 1). However, it has been found that most of the SSI is located near the main roads. i.e., Bagamoyo road, Sam-Nujoma road and University main road. Figure 2 depicting SSI located in interior streets of the Mlalakuwa. However, car repair workshops, wood processing and furniture workshops were seen to be located close to main streets. An interview with a customer at car repair workshop narrated: (…) "I often prefer to use this garage close to the main road because it's easier to access. As you can see, there are many of potholes in the streets of Mlalakuwa neighbourhood. During the rainy season, the potholes are full of water and it becomes difficult to drive on interior streets. And of course, along the main road we can get other services, like bars and shops, which are everywhere" 4 . This implies that SSI activities which located along or near by the main roads they have privilege of getting more customers because of flexibility and proximity to main roads. The study revealed that they are three car repair workshops located near to the University road, four along Sam Nujoma road and two car repair workshops on the side of Bagamoyo road which seems to be convenient for most of the customers at Mlalakuwa and adjoining settlements easily access for services. Source: Adopted from , (Tesha, 2020) and updated during Fieldwork, 2020. Current Urban Studies Source: Adopted from ARU-architecture fourth year students of 2019. The study revealed that Lufungila and Mpakani along Sam Nujoma road and other areas along Bagamoyo road and has massive collective spaces for Small-Scale industrial activities, and they are located close to the sides of the main roads.
These areas have several steel workshops and more than 70% of Small-Scale industrial activities, taking advantage of the availability of customers and accessibility to other parts of the city (Figure 3(a) and Figure 3  us to make the same steel furniture that they saw on the internet" 5 .
This implies that SSI becomes an important self-developed sector which becomes an alternative employment for people who are not employed to formal sectors. This also has been sensitised by politicians that people had to employ themselves as there is insufficient employment opportunities to public sectors.
However, young people who practising SSI activities will continue to be given an opportunity by the government to establish themselves including getting loans for the developing their small-scale industrial activities 6 .
Apparently, it was observed that the SSI activities are legally practising at Mlalakuwa because most of them have registered to formal institutions like BRELA 7 and TRA 8 and recognised as low-income earners. SSI seems to have contribution by paying taxes and levies to the government. A narration regarding the SSI op- ties at Mlalakuwa area. They pay taxes and levies to the authorities, which is very important for them and the community at large. There is a little slight challenge that I would say to these people. I have some cases against some of these SSI operators as they block streets and give out challenges to other street users. So we, as local authorities, are finding different ways to solve this problem of misusing the streets. I hope that at the end of the day, we are going to have a better solution for that" 9 .

The Impact of Small-Scale Industries on the Emerging of Collective Spaces
It was observed that Mlalakuwa is a mixed informal settlement that is dominated by single-story to two stories building typologies, and more than three stories to some commercial buildings along the University and Sam-Nujoma roads . However, it has been seen that the front domestic spaces are mostly used for many functions including the operation of Small-Scale industrial activities like sewing and shoemakers were seen to operate in domestic spaces ( Figure 4(a)).
Collective spaces surrounded by buildings were converted to garage workshops, sand and cement block workshops, where verandas are quite often converted to offices for garages (Figure 4(b)). On the other hand, buildings collective spaces are converted to car spare shops and parking spaces close to main car repair workshop ( Figure 5). Also, these spaces have been used by motorcycle   operators quite often to wait to pick up car owners who might need a quick transport to other parts of the city while their cars are still in repairing process. It has been observed that spaces along service roads and pedestrian ways were converted to parking for repaired cars, whereas in some areas, spaces were used as products display areas (Figure 6(a)) and Figure 6(b)). Presence of Small-Scale industrial activities at Mlalakuwa changed space use to a great extent. Collective spaces available were converted to adopt the functional and operation of Small-Scale industrial activities. A carpenter found during field observation narrated: (…) "We have limited spaces here. For instance, we have several activities around us and we need more spaces like a workshop area, storage, an office, and a display area. We have tried to maximize the use of space, but we still we don't have enough space to display our furniture. That's why we are using this pedestrian way as a display area" 10 .
This implies that SSI activities at Mlalakuwa are the source of collective transformation. As many spaces transformed by reflecting the nature of activities. Other collective spaces along streets adopted to suit a different SSI industrial function. However, the limited space and population increase also have been source for SSI to contribute increase the use of collective spaces at Mlalakuwa.
It was found that more than 40% of Small-Scale industrial operators responded 10 An interview held on June 2021 with carpenter at woodwork shop at Mlalakuwa. positively, that more spaces were needed to run their activities. However, 23% of the residents from adjoining settlements suggested that there is a need for collective spaces for people to interact apart from the existing collective spaces where seem to be the main area for Small-Scale industrial production. And 15% of employees' respondents suggested common spaces needed for other activities like displaying areas and waiting areas, which are most convenient for the customers (Table 2).

Supply Chain and Spatial Development
Existing literature (Bernstein, 1982;Fiori & Brandão, 2010)    physical concept that is attained by the goal of being free to eliminate the gap between the rich community and poor communities to encourage development that covers social inequality. Streets and collective spaces have become important economic drivers for spatial development at Mlalakuwa informal settlement neighbourhood. It has been found that there are two ways economic drivers and networks formed the spatial patterns within the settlements through an examination of the qualitative data. Within the case study area, there are internal and external economic drivers' networks whereby the external supply chain depends on resources like vehicle spares imported from Dubai, China and Japan 11 and woods mostly from Sao-hill, Mufindi in the Iringa region they are transported to Buguruni area. All resources from the external supply chain were brought to Kariakoo 12 as the main distribution point of many types of products from abroad and upcountry that are used for SSI sectors in the city of Dar es Salaam (Figure 7(a)) 13 . Buguruni area also found to be the main distribution point for wood resources Source: Field Survey, 2019. Figure 7. Some important shops at Kariakoo and Buguruni area for supplying raw materials to Mlalakuwa. 11 An interview was conducted in February 2020 with one of the owners of the car repair workshop located near sky-mall along university road. 12 Kariakoo is a ward in the Ilala district of Dar es Salaam, Tanzania. The name derives from a corruption of the British "carrier corps", which used to be based in this area. Today, Kariakoo is mainly known for its extensive market, which spans several city blocks. 13 An interview was conducted in February 2020 with Mlalakuwa SSI operator.
to Mlalakuwa neighbourhood which enhance the increases spatial development at Mlalakuwa (Figure 7(b)).
The internal supply chains are necessary for processed products like furniture making, at point (a) e.g., steelworks, block works, etc. SSI, such as carpenters, sofa makers, welders-any sorts of trade involving furniture making, follow at point (a) in (Figure 8). However, the places are easily accessible that create dispersed movements of spatial pattern along Samu-Nujoma, Morogoro and Alhassan-Mwinyi roads towards those distribution areas to accelerate and ease the flow of materials to run the Small-Scale industrial activities. There is still vast evidence that the clustering of the furniture making points at all main roads at Mlalakuwa neighbourhood.
Most Small-Scale industries range from carpentry furniture production and tailor production, steel fabrication, vehicle repair, metal doors, windows, etc. The study revealed that 33% of furniture workshops contribute to a large number of economic activities due to the high demand for products needed by customers. The need of products from this SSI means operational spaces also needed to accommodate all functions. It is clear that operation of Small-Scale Industries, Source: Masters students KU Leuven ELBG1 Urban Projects, Collective Spaces and Local Identities, 2019. is expanding and likely contribute the emerging of collective spaces since the increasing the space usage which will later affect the space value.

Conclusion
This paper aimed to explore the legibility of SSI in informal settlements and understand the process involved in the formation of the collective space at the Mlalakuwa neighbourhood. Among other empirical regularities, small-scale industrial activities are highly correlated with the city's socioeconomic and physical realities at Mlalakuwa informal settlement. Furthermore, SSI emphasizes the legibility of self-developed activities which model collective space in informal sentiment in many ways. The area is surrounded by major activity clusters, which leads to insufficient public and productive space. The study revealed that small-scale industries are the outcome of the insufficient economic development planning strategy of many developing cities. Despite the effort made to improve the informal areas in the city of Dar es Salaam, small-scale industries have become an important aspect that contributes to the growth of the economy, leading to the growth of urban.
It is important for local authorities and small-scale industrial practitioners to have a great emphasis on identifying the legibility of SSI in informal settlements because they play a great role in changing human lives. Generally speaking, a rationale for policies should be changed that aim directly at shifting ideological perspectives from formal employments to SSI activities. This sector was found to absorb a large number of unemployed communities in formal sectors. The operations of SSI are seen to be a source of collective space transformation where buildings and open collective space are altered to mitigate SSI specifications.
However, authorities and development actors should intervene in the rising usage of collective spaces that interfere with the interests of other users which is not perceived as an issue.
