Mopti is a town located in Mali, in the Sahel region of West Africa. Mopti has a population of 114,296 people, and has a total area of 40km2 , resulting in a relatively high population density of 2,900/km2(World Bank 2015). Being in the Sahel region, Mopti has a hot semi-arid climate, which has influenced the shaping of Mopti’s urban fabric. Mopti is also situated within the Inner Niger Delta, the inland delta of the Niger River. Specifically, Mopti is located at the confluence of the Niger and Bani rivers. This vast floodplain, along with Mopti's very low lying flat topography expose the town to recurrent flooding, characterising Mopti’s urban layout. Mopti consists of three regions; new town, old town and the medina coura. These three regions are linked by a 12km elevated causeway that connects the town, and follows into the adjacent town, sevare. Evidently, Mopti’s geographical context exposes the town to frequent climatic stresses.

This presentation will explore how the city of Mopti has developed and what may have been the most influential factors for the growth of the city. We will be looking at this from an environmental perspective, focusing on how climatic stresses that Mopti’s arid ecosystem experiences, characterizes the city’s identity.
THE HISTORY OF MOPTI
It can be assumed that the access to an abundance of water in the hot semi-arid climate of Mali would have been the predominant driving force for Mopti’s settlement on the bank next to the confluence of the niger and bani rivers.
1758 was the first record of Mopti settling with approximately 150-400 of the principal fishing people of the Inner Niger Delta, the Bozo people as a fishing town surrounded by cultivated fields and grazing land. The town began as two small conglomerations, within the region of the old town. This can be presumed from the high density, highest topography and settlement patterns, which will be explored further on in this assignment. In 1800 the town was officially given its name of Mopti by the Fula people, meaning a place of gathering. John Friedmann (2010) , noted that it is a structural imperative for cities to come into being though the recognition of the importance of a location or territory, and a place where people with a common mission or value can come together. In 1818 the village became part of the Massina Empire. Islamic presence was established, thus the introduction of Mosques, Madrasa’s began to appear (African architecture. (2019)). In 1893 the village became part of the French Sudan. As a result, Irrigation systems were introduced along the Niger River, allowing for slight expansion of villages.

POPULATION DENSITY
Mopti consisted of several separate settlements on small areas of higher ground that remained above the water during the annual floor. Mopti contained 700-800 inhabitants. Houses made of constructed of sun-dried mud bricks began to appear and Inhabitants grew rice on the floodplains, herded livestock and fished with cotton nets. Fish and pottery were sold in Djenne and to boats heading to Timbuktu. Mopti became a town of high commercial trade value due to its geographical location (Douny 2014). In 1930 French colonial forces constructed a 12km Dyke connecting Mopti with Sevare to allow access to the town when the Niger was in flood as well as enhance trade routes to enhance the economic value of Mopti. Commercial Area’s on the river and the New town district had also been developed.In 1960 the town experienced considerable population growth after independence (Harts-Broekhuis, A. (1997)). Then in 1970, Mopti faced a lengthy spell of dry years and experienced disappointing outcome of various development efforts. This could be a reason for the population growth stand still in the past. However, in 1980 the town of Mopti suddenly became a refuge for thousands of impoverished rural refugees. This drift to town was stimulated by the mechanism of food aid distributed in Mopti, resulted in the rapid growth of the very poorest stratum (Harts-Broekhuis, A. (1997)).
Mainly the environmental stresses, however symbolic, political and social events have characterised how Mopti has been built and has developed as a busy highly dense commercial city.

Centre of Architecture
Mopti's Port Industrial Building's
Mopti’s heritage consists of building’s that posses architectural qualities and attributes reflecting significant environmental, political and social historical events. For example, an earthen structure built in the traditional Sudanese style between 1936 and 1943 on the site of an earlier mosque dating from 1908, is commonly called the grand mosque of mopti. The first phase of the work on this important landmark focused on repairing the roof and stabilizing the upper part of the building, which had been damaged by the inappropriate use of cement in a previous restoration effort in 1978 (African Architecture 2019). Because cement adds additional loads to the structure and integrates poorly with the traditional materials, earthen buildings clad with cement often suffer water infiltration and structural damage over time - a process which, in this case, had weakened and seriously compromised the stability of the monument. Fissures in the cement cladding applied in 1978 (African Architetcure 2019)have been infiltrated by water, which has led to structural damage and compromised the stability of the building.

On 14 October 2004, the monument was formally inscribed as an official landmark in the nation's cultural heritage by the Minister of Culture. Thus, this important monument has continuously been restored to reproduce its lost characteristic, to continually represent the importance of Islam as a country-wide religion. This approach was championed by Eugene Emmanuel Voillet-le-Duc in the XIX century (Mirko 2020). It is important for this restoration process to occur because through the different forms and materiality’s people are reminded of Mopti's religious, political, social and environmental values, attributes and meanings which distinguish the city’s Identity.

URBAN STRUCTURE
Mopti’s urban structure consists of both an organic and grid-like layout (mirko 2020). Both layout patterns however are oriented off a main north-south running axial points; the adjacent Bani and Niger rivers. Additionally, there is a second major axis point; the elevated causeway that mimics the north-south facing river axial point.
In the beginning it can be interpreted that Mopti evolved spontaneously, representing a more organic layout due to the influence of the topography and towns respective susceptibility to flooding. This organic layout as seen on the diagram is oriented with the river as the major axial point of the city grid. This is evident as all roads run off the river. The primary axis defined by the waterway reveals the importance of the river has had to the city settlement. The new town as well as the original settlement location within the Old Town represent an organic layout. These areas consist of more commercial and industrial buildings. These area’s represent the city’s oldest regions, due to their prime location and the density of the areas. The positioning of these areas are represent the importance of their proximity to the river, which is most likely due to the river being a main trade route for the city.
The second major axis point; the elevated causeway was implemented later in the city’s development. The areas developed off this axis point can be seen to represent a more formal grid-like layout. This includes; the eastern residential side of the old town and the medina coura region, where majority of residential typologies are located. This could be a result of these areas being formed as a result of rapid urbanization, as an quick effective method of land organization and subdivision of heavily dense residential requirements on limited areas high land, due to restricted land availability as a result of flooding.
Overall, Mopti’s urban structure has been developed with restricted land availability due to seasonal flooding. This has naturally formed an efficient layout combining organic and grid-like structures running off the main axial points; the river and elevated causeway. This layout has been an effective method for the required layout of the highly dense residential and commercial focused town.
Mopti's primary road has been strategically placed on the highest ground to ensure its reliability during flooding.
The diagram reveals that Mopti is a compact, mixed use, walkable, dense, and generally socially integrated town. Evidently the secondary roads within the town, motorcycles, bikes and walking are the primary methods of transport. Thus, the proximity of functions and facilities as seen on the diagram are spread out to enable this to occur in the urban environment. Due to the high density of the town, this is seen as the most efficient paradigm in regards to the mobility system. This can be seen presumably to avoid congestion and allow for available land to be used effectively for building space rather than transport routes.
In regards to inadequacies of land transport and the town as an important town of commercial trade, the Niger river acts as an important transportation link in Mopti and has since settlement. The Niger is navigable throughout its length year-round for small boats and from August to December for larger vessels. The port of Mopti is served by ferries which run when the depth of water in the river is sufficient. They carry both freight and passengers. Both passengers and freight are also transported by pinasses, large wooden canoe shaped vessels, that are privately operated. The other important transportation link is Mopti’s primary road, the 12 km elevated causeway to Sevare which lies on the Route Nationale 16 (RN16).
It can be deduced that the primary road is used mainly for commercial purposes, to come into and out of Mopti and to travel between the three regions within Mopti. However, more so the secondary roads are more frequently used for residents to go about daily life.

This functional analysis diagram is a useful approach to understand how Mopti’s functions and how its different parts relate to one to each other, and how the overall design of the city supports communities (mirko 2020).
From the diagram you can see that the most dominant function of Mopti is residential, mostly high-density, single story or double story houses. This is to accommodate for the cities rapid growth and facilitates the increase in population expected whilst maintaining to stay out of range of the floodplains. This is a contributing factor to the ontology of the city. Commercial and Industrial buildings are also a predominant function evident on the map. This suggest Mopti has strong values towards representing a strong economy and city of trade. These functions, although slightly scattered amongst Mopti are dominantly located in the New Town surrounding Mopti’s main trade port. Although, from the diagram you can see different functional buildings are an integrated system, due to the proximity. It can then be assumed different groups of people and different social groups share the same space in a highly mixed use and integrated landscape (Mirko 2020). Additionally, streets as well as the function of Mosque’s are seen to be ‘social spaces’. This is also evident due to the lack of squares and centres within Mopti and due to the lack of land as well as planning of the city layout.
Lefebvre, H. et al. (2014) argues in The Production of Space is that “space is a social product, or a complex social construction (based on values, and the social production of meanings) which affects spatial practices and perception. (Social) space is a (social) product ... the space thus produced also serves as a tool of thought and of action ... in addition to being a means of production it is also a means of control, and hence of domination, of power. “ This can be seen to be relevant to Mopti as Mosque’s are an important centre of cultural and social life, for Mopti’s considerable Muslim population. Additionally, it can also be deduced that Mosques represent a sense of Power of the country wide Islam religion, which is also revealed in the size of the building typologies compared to other recurrent buildings in Mopti.
The relationships between these building functions will be further explored in the Building Typologies section.

The map reveals seasonal flooding and the respective areas affected in the Mopti region. You can see from the map that the city is built on the margin of the flood region, if not in some cases already on the flood prone region. This is due to the requirement of land because of Mopti’s heavily dense population. The Niger and Bani river is very intimidating on the eastern side. It is surprising that the dependent functional buildings including commercial and industrial are placed so closely to this flood prone region. However, it can be assumed that the proximity to the river during de-flood season is worth the risk and the trade benefits must outweigh the risk of flooding. It can also be seen that the high-density residential building are build on the highest topography furthest away form the river. It is assumed that because the residential density decreases the closer the proximity to the flood plane, is due to their requirement to be located there for agricultural purposes. From this diagram it can also be determined that growth of Mopti in the future may face problems due to the flood prone areas seriously restricting land availability for development.
Mopti lacks active irrigation but employ dikes and sluices to delay flooding, and to manage the water level during deflooding. These polders are typically characterised as ‘controlled flooding’ or ‘passive irrigation’.

To understand the urban morphology of Mopti, we will examine its form determined by the relationship between recurrent building typologies and open spaces. Alberti, in his definition of a city, stated: “Accordingly to the philosopher the city is a big house and, on the other hand, a house is a small city”(Mirko 2020). In this analogy, streets would be corridors connecting different parts of our house; squares, on the other hand, would be rooms where activities take place. This highlights the most recurrent building type’s as a particular feature of each city, or part of city and how they interact with the space around them, providing character and identity to a specific urban environment. I believe this is relative to Mopti, due to the limited recurrent building typologies that generally share the same materiality, however, can differ significantly in their form and internal layout. As can be seen in the diagram on the left, Mopti mainly consist of four main building typologies. Residential is the most recurrent building typology, followed by commercial, industrial then Mosques. The area outlined by the white box on the diagram is the selected area of focus. I believe this area provides an ample representation of the relationship between different recurrent building typologies and their connection with space.

BUILDING TYPOLOGIES THAT CHARACTERIZE MOPTI'S URBAN MORPHOLOGY
characteristics of recurrent building typologies
from this diagram we can view the different exterior forms of the different recurrent building typologies of mopti and their connection with the street scape. Similarities that can be seen between the typologies include the incorporation of vernacular earthen architecture understandings. this is evident from the open layouts of buildings allowing for natural ventilation within the buildings. A consistent construction material used for all of the building typologies is earth and clay, specifically, semi-desert chestnut earths and laterites (reddish residuals of rock decay), characteristic to West Africa. The nature of this building material restricts the height of the buildings (except in special cases; Mosques) connecting the low sitting town with its surrounding landscape. in the diagram it can be seen that commercial buildings are surrounded by free space with an open layout that generally faces towards the primary axis of the city. The space surrounding the commercial building generally contains trees to allow for shading for the public. Mosques have a similar connection with the street space to commercial buildings, due to these two typologies being seen as a 'social gathering space'. Residential buildings however appear more confined and closed off to the main pathways, creating a sense of security. this is similar to the industrial building typologies. Residential buildings also appear to have central courtyards with a central tree, to allow for natural ventilation and shading. One of the principle causes of building deterioration in Mopti is the water infiltration into the structures as a result of poor infrastructure including drainage and sewage systems. different urban fabrics can be identified by recurrent typology layouts, which will be examined by looking at the internal distribution of each building typology individually.

Single story or multi story residential dwelling are identified by their compact rectilinear polygon formations and with Wooden doors often decorated allowing for expression of individuality. Additionally many residential dwellings have a courtyard in which a singular tree is planted for shading purposes as well as a flat roof, where the inhabitants can sleep in warm weather. The thick walls are also well suited to the regional climate, their large thermal mass ensuring that indoor temperatures always remain comfortable despite fluctuations in external temperatures.The building is naturally ventilated through openings in the walls, which also enables natural lighting.
Mosques are an important centre of cultural and social life, for Mali’s considerable Muslim population. Mosque building typology can be recognised by its Sudano-Sahelian architectural stYle consisting of wooden beams with exposed ends that are used to reinforce the towers. The skilful use of this material, is called banco coupled with palm for floors and roofs has evolved over time into a distinct architectural language that is best described as a unique blend of indigenous forms and Islamic traditions. their monumental and fortress-like exteriors act in a way as a ‘defensive architecture’. The Mosque layout it identified by a courtyard on the Western side, flat roof where prayer takes place and adjacent minaret tower. The work on the exterior focusses on establishing effective falls for the rapid draining of rainwater from the site. mosques can be seen as the most grand building typology in mopti due to their overwhelming size in comparison to all the other building typologies.
Commercial buildings in Mopti are all one or two story structures, characterized by their large open layout, and occasionally with the addition of makeshift tin shading on street side. The main roadway facing entrances are also a recurrent characteristic, due to the welcoming nature of the commercial buildings. Commercial buildings are generally seen in small clusters, often with a layout that encourages people to flow through.

HERE WE WILL EXAMINE MOPTI'S LANDSCAPE AND STREETS AND HOW THEY CONTRIBUTE TO SHAPE urban form and characterize mopti's perception through the elements of mopti . Understanding these main elements can guide the understanding of a city, its character, its social dynamics and its urban form.
Nolli map
Street Scape Section
Looking into structural form and functionality of Moptis urban fabric, it is clear that streets, public corridors and alleyways are distinct public spaces that link districts and areas within the city. While residential buildings are private dwellings that are connected by small pedestrian alleyways. Religious spaces are an interesting structural type as they are closed public spaces that don't particularly encourage tourist access, focusing more so on traditional religious activities for residents. The Nolli map shows that the main street facade acts as the primary entry and point of advertisement for commercial buildings as well as residential and religious structures. Alley ways and secondary access roads also provide more secluded entries to structures, this could mean access points to certain parts of the dwelling or building are deemed private. Public spaces are linked by pathways and grouped squares, while several amorphous squares occur in situations where new districts and distinct building typologies have been introduced.
Recognizing the relationships between open public, open private and closed private spaces reinforce the importance of social areas, introducing the notion of informal or organic urban areas that engage community interaction. these negative corridor's of open public space elaborate on community character, social and cultural values and urban design particularly through viability of social practice and cultural style. Due to the high density city fabric, the restricted street size of mopti limits vehicle movement, creating communal zones in between buildings and linking node and landmarks. The proximity of spaces enhance community familiarity and create a significant sensory experience that contributes to the perception of the city. Jane Jacobs (1994), a North American activist who has deeply influenced contemporary urban design, promoted the idea of how people is what make a place vibrant and interesting, how people is a central factor in generating a sense of place. She popularised the eye on the street theory; places actively used by people would be safer because people look after other people. Mopti’s streetscape is a representation of this urban design approach in which people are placed at the centre. I believe, because of this Mopti has been effective in achieving a connected strong resilient community, which is portrayed to visitors through the street scape perception.

Personal experience plays an important role to inform our interaction with the urban environment. The ‘sense of place’ is in fact a complex interplay of different conditions that allow us to charge a space with a meaning. Using Kevin Lynch's (1981) concept of imageability of a city, we an understand how people perceive and navigate an urban environment. From analysing Mopti’s streetscape we can see Lynch’s five distinct elements that form the urban structure.
Paths are heavily evident in Mopti, and are used as a primary mode of transport in which residents customarily move. Paths outline the main roads, however are not as frequently used as the paths that run in and out of the backstreets. It is common to have a path linking residential buildings to a communal courtyard. The paths are only evident from high use, there is no infrastructure put in place to identify the paths. This allows paths to be virtually made by anyone anywhere.
Edges in Mopti are generally defined by the transition between different building typologies including mainly residential, commercial and mosques, by geographic landmarks including the river or by the few main transport routes that run through Mopti.
Districts are identified by the building typologies which were identified in the Morphology of the city analysis. Due to the lack of building typologies in Mopti, these distant forms clearly identify the different districts.
Nodes are found predominantly on the river in the Old town and in the New town as this is where most commercial, inductrial government and education facilities are located. Nodes can also be seen as places of interest including recreation facilities , or mosques.
The main landmark in Mopti can be seen as the Mosques. This is due to their large structural dominance compared to any other building typology in Mopti, enabling them to stand out.
These difeerent elements that form the perception of mopti are shown in the sketches and diagram to the right, representing how Kevin Lynch’s concept of imageability of a city HAS BEEN constructed in Mopti.

After exploring how the city of Mopti has been developed and the most influential factors for growth of the city, it can be deduced that the climatic stresses; Mopti being A semi-arid ecosystem that experiences seasonal flooding, has characterised Mopti’s urban identity. This was determined through the use of analysis methods from the French, English and Italian Schools of Urban Morphology, as well as different urban theories. The location of Mopti on the Niger and Bani River confluence has been the focal point of the city since settlement due to accessibility, transport and fishing opportunities. This has enabled Mopti to be an economically thriving city of trade, with a rich cultural heritage. However, Mopti is currently a heavily dense city, with limited land availability for development due to intruding seasonal flood patterns. Thus, if the current high rate of population growth continues, development may be seen impinging on seasonal flood prone areas. This is as the city is unlikely to develop vertically due to its building typology form and material restricting it to do so. Thus in the future, careful urban planning will be required to address these climatic stresses to ensure Mopti continues to retain the site responsive urban layout that has proven to be effective, whilst also adapting to historical and political ontologies that have shaped Mopti to be the important commercial town it is seen to be today.
