A city is a large human settlement. People are the main driving force in a city. The dynamism of a city is dependent  on people and their behaviour. A preliminary understanding of the composition and diverse capabilities of the populations in a city should be the key to a successful urban study.

Predictions made by identifying demographic and composition patterns of the population within the existing physical boundary will create a well-planned livable  city.

Education

Education has always been a significant element in societal development. The development of education facilities contributes substantially to the development in an urban area.

As a developing country it is crucial to address poverty in order to attain the development goals. Education plays a major role in poverty reduction. Presently, several global cities have been implementing the concept of smart city to improve the quality of life of the society, including in the field of education.

Good educational institutions and coverage enables a population to have decent livelihoods be they self employed or part of the workforce. Understanding how a city provides primary, secondary and tertiary eductional as well as skill development through vocational centres could provide some pointers to how well a city is doing or where it needs to develop further.

Transport

Connectivity is central to key GoSL strategic aims: to promote economic growth, and to rebalance growth across the country’s 9 provinces. Higher the connectivity to any city, better is the urban growth in that city. 

Detailed information on key transport aspects including bus and rail transport, freight route maps, airports and logistic systems are aspects that should be considered for a city to be properly interconnected within the bigger system. One of the SDG targets 11.2 is about access to safe, affordable, accessible and sustainable transport systems, road safety, public transport, and if we are to move towards being sustainble, these need to be considered in tranpsort planning. Further, the needs of people in vulnerable situations, women and children, persons with disabilities and older persons should also be considered.

ICT coverage is another way of being connected and recent technological advances enable a city to be better connected through its access to ICTs as well.

Economy

Cities are the primary drivers of economic development, therefore, Sri Lanka’s cities have a decisive role to play in driving the economy forward by catalysing high value-added economic activities, as the country strives to achieve upper middle-income country status.

According the latest Word Cities report, 80 per cent of global GDP is created by cities, despite their accounting for less than 60 per cent of the world’s population (UN-Habitat, 2016).

The Government of Sri Lanka recognizes the role of urban economy in shaping the future of the country. In this respect, Vision 2025 and Public Investment Programme (PIP) 2017-2020 lays out the urban policy priority actions: to promote western region as economic hub of the southern part of the Indian subcontinent, and to promote strategic city development to secondary urban spaces as provincial economic hubs. 

It is also interesting to see how competitive a city is, taking into account current and potential roles of governments, businesses and the private sector in the economic development of the city and urban settlements, best use of human capital,  and labour force participation, and existing skills and the job market etc. within demarcated territory.

Urban Governance

Urban governance can be simplified as “how government (local, regional and national) and stakeholders decide on planning, financing and managing urban areas”. It involves a continuous process of negotiation and contestation over allocation of social and material resources and political power.

This section provide a snapshot of the emergent contours of urban governance in Sri Lanka, focusing on financial resilience, service provision and economic dynamism.

Information available here are collected and calculated considering secondary data sets, ground level surveys as well as stakeholder discussions. The city governance index has taken many a factor into consideration and provides a valuable way of assessing our cities and how they rank from a governance perspective.

In Sri Lanka the LAs are divided into three types according to its population and size: Municipal Councils (MC, 23) which corresponds to the city, Urban Councils (UC, 41) which corresponds to the town, and Pradeshiya Sabha (PS, 271) which corresponds to the village. They are responsible for providing a variety of local public services including roads, sanitation, drains, waste collection, housing, libraries, public parks and recreational facilities. This pie chart shows the distribution of LAs by province in particular local authority belongs. Sabaragamuwa Province include 1 MC’s, 3 UC and 25 PS’s. Ratnapura is the provincial capital city of Sabaragamuwa province.

Housing

An important function of Sri Lanka’s cities is to provide housing for the diversity of residents that support urban life. Sri Lankan early urban settlement legacy – histories, patterns, trends including land use and housing and the development challenges that come along with it have shaped the nature of our cities.

The share of housing as a proportion of built-up area across the different cities was considered, and numerous factors affect the figure. e.g. Anuradhapura, has restrictions on residential developments because of its cultural, historical and touristic importance, other MCs include significant social and economic land use, operating as a hub to surrounding suburbs and rural areas with large residential populations.

Housing policy challenges that are encountered by the city administrators relate to tenure systems, the supply of affordable, high quality housing, and difficulties accessing housing finance.

Municipal Services

Municipal services is one of the key tasks an urban centre carries out fto ensure a functional living condition for its citizens.

The access to municipal services and the quality of their provision strongly influence the social, economic and environmental performance of a city as well as urban development.

Urban centres provide key services that underpin Sri Lanka’s socioeconomic development. Cities provide key government administration functions, such as vehicle registration services, access to social protection schemes, and a range of additional services (explored in detail in Chapter 9, urban governance in the SoSLC Report). Urban centres provide residents with health and education services: providing equitable access to quality healthcare and education. They also include services to facilitate social recreational activities and promote community cohesion, such as libraries, community centres and sports facilities. Ensuring quality services is a crucial component in securing an urban future for all Sri Lankans. 

Solid Waste Generation and Collection

Source - IWMI Publication - Solid and Liquid Waste Management and Resource Recovery in Sri Lanka: A 20 city analysis

MC collects about 30MT of waste everyday and only 50% of the collected waste is sorted into organic and inorganic waste at the source of generation. Essentially, residential sources contribute to 45% of the waste collection. Waste collection schedule is such that the waste in the urban center, common areas and the areas located along main roads are collected daily as door-to-door collection whereas the byroads are visited 03 days per week to collect the waste generated in the entities located along the byroads. At present, the MC practices to open dump the majority of the collected waste in a land belonging to the municipal Council in Kanadola area. The dumpsite is located about 3.5 km away from the council office. There is also a Compost plant and a recycling centre located in the same land in Kanadola. In general, collected solid waste is brought to the disposal site and about 3 tons of waste is used to produce compost. About 1% of the waste is being recycled and the rest (approx.26 tons) is disposed following the method of open dumping. This site is located at a high elevated area with a steep slope to the ground below where the agricultural and residential areas are located. Consequently, impacts on humans and the agriculture caused by the current waste disposal practices appears to be extreme.

Environment

A city needs to have an environment that is habitable and conducive with appropriate spaces for people who use the city, while also being resilient in the face of increasing climate risk.

Aspects such as a cities’ air and water quality, quality of the built environment as well as the aesthetic and historic aspects in the city are things we need to look at. However, in the light of increasing disaster risk, managing climate change impact in the light of current urbanisation patterns becomes a key concern, and thus land use planning in a city needs to take this into account.

SDG targets 11.4 (safeguarding cultural and natural heritage) and 11.5 (reducing impacts of disasters, especially floods), 11.6 (air quality and waste) and  11.7 (safe, open and green spaces for all groups) all emphasize that for a city to be sustainable, these aspects need to be considered.

Flood Data

Proper management of land, a scarce resource, can bring about many benefits. This is of great importance especially in urban areas.

 

It is timely to figure out how land is allocated and being used for what purpose in our cities today. In order to create well planned cities with a futuristic vision, having a better understanding of current land use is imperative.

 

Land use maps are categorized into 36 sub-categories under two types – built-up and non built-up. The extent of land in each of these sub categories are indicated below.

In all of the cities it can be identified that the higher densities are concentrated in the city centres and the expansion is taken place along the roads. The expansion pattern is shaped by the geography of the surrounding area.

 

The selection of the area for the urban expansion analysis was followed by several preliminary studies. Initially, the urban index values which was identified using the remote sensing information were studied in the respective municipal areas including a fringe area.
Before selecting interested area for the expansion analysis it should consider following facts
- Municipal boundary
- At least 2-3 km buffer around Municipal boundary
- Rough boundary where the physical urban character disappearing

 

In the remote sensing discipline, the values higher than 0 represent the built-up areas.The boundary for the fringe area was identified by getting the extent of urban expansion as well as a fine boundary where the high-density expansion become insignificant. The identified boundaries were projected on to the latest satellite images to assure the identified urban index values are in line with the existing building densities.
