I think geographical factors like healthy climate, water availability, connectivity by road, railway, air, hill station etc. and socio cultural diversity, heritage, rich cultural traditions etc.

Hi. Different geographical or socio-cultural factors does have significant influence on sustainable urban development. However, it is better to define the scope of sustainability first, so that you can have a clearer picture on how the impacts posed to the urban development.

If public acceptance and participation in decision making is considered as one of the contributing factors to the sustainable urban development, then I can suggest to you an interesting case study in Japan about the public participation in community development and landscape design.

"Machizukuri" is a Japanese term, referring to the community development, which is a process where community members come together to take collective action and generate solutions to common problems. It started as a problem-solving strategy, to address problems facing Japanese cities such as

• The decline of the traditional shopping ( Shôtengai )
• Districts with dense, catastrophe risk and partial demolition mature wooden houses
• Shading and soil sealing
• Conversion of industrial wastelands
• Deficiencies in the road network: narrow streets and dead ends, lack of arterial roads, lack of accessibility
• Needs of an aging population

It is by far the most interesting planning strategy that fully incorporating local knowledge into town planning and design. Please find further info on Machizukuri in the attached document. Thanks.

The climatic condition of a place and natural resources in an environment can sustain population growth in and urban city. For instance in a state like Lagos in Nigeria with over 30 million people keep witnessing population upsurge because it is a town surrounded by water and majority of Nigeria importation is through Lagos because the city is surrounded with water. Geographical endowment like natural resources such as crude oil has kept attracting people in the cities of Bayelsa and Rivers state Nigeria because most establishment that come for the exploration of this crude oil require other ancillary services to support their establishments therefore attracting people and investors. Moreover, on the Northern side of the country, the Igbos keeping migrating to the north due to the hospitable-business climate over there which might not be unconnected to the cultural life style in northern Nigeria. HOPE THESE EXAMPLES WILL HELP. 

There are different factors responsible on the sustainability of urban growth such as:

1. Rural-urban migration.

2. Increased household income.

3. Topographic factors such as : slope, soil, elevation, and so on.

4. Economic aspect.

5. Unbalanced Spatial development.

6. Regional Development.

7. Nature resources.

8. Urban planning policies.

9. Social aspects such as poverty.

10. Focusing on horizontal growth rather than vertical growth.

traditional factors include; cultural institutions and services, land inheritance, available space for urban agriculture etc

Security; presence of local/government security institutions and services, feeling neighborhood cooperation, sense of .indigineship security

geographical; favourable climate, rich soil that meets agricultural need, flat terrain, availability of surface and underground water, local/regional transport network connectivity etc.

social amenities; energy or power supply, water supply, communication networks, tertiary and quaternary services
