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.

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.

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.
