Brownfield vs Greenfield development

Consequences of land use change

Brownfield or Greenfield – Which is best?

Brownfield - A site that has been built on before and is

ready for development. Normally associated with

urban inner city areas

Greenfield – A site that has not been built on before. Often

rural/countryside areas. This includes the rural-urban fringe.

Land use change – multipurpose land use is more sustainable

• How sustainable is developing a Brownfield site compared to a Greenfield site?– Quality of life?– Access to services & jobs?– Waste disposal and costs involved?– Energy savings?– Cost to environment?

Disadvantages of Brownfield Sites Disadvantages of Greenfield Sites

What are the Advantages and Disadvantages of Brownfield and Greenfield Sites?

1. Brownfield redevelopment eases pressure on Greenfield sites and is more sustainable – Its good to reuse land

2. Greenfield sites are often on the edge of towns and cities and may have better access, have less congestion, be in a more pleasant environment and have more space to expand

3. House prices would increase in inner city areas as people are encouraged back into the area

4. Infrastructure already exists in urban areas

5. Building on Greenfield sites ‘sucks’ out the core from towns as shops, etc locate on the edge of towns/cities

6. New employment opportunities if Brownfield sites are developed

7. New housing can lead to gentrification (old housing done up – area becomes more trendy and affluent) so the area will improve and statistics like crime rates will improve

8. New sites are easier to build on as there is a fresh start, where remains of previous land-use do not need to be cleared, and is more attractive to retail parks, housing developers, etc

9. Providing public transport networks is easier in central areas where the population densities are high – investment is focused in central areas

10. There may be an issue of contamination and making sites safe for development, given what the land may have been used for before

11. Towns and cities do not want their areas to decay – redevelopment results in more people coming to the area, which helps local businesses

12. Using Greenfield sites is often not sustainable

13. Increased house prices due to inner city redevelopment might mean that local people cannot afford the houses, and the council will have the problem of providing for them

14. In Greenfield sites new drainage, electricity, roads, etc would all have to be produced

15. Building on Greenfield sites may reduce traffic and congestion in cities

16. Wildlife may suffer when Greenfield land is built on – may lose habitats, trees may have to be cut down, etc

17. Large family houses with gardens are more likely to be able to be built on Greenfield sites – often not enough space for this in Brownfield areas

18. Redeveloping Brownfield sites can bring a ‘dead’ area back to life

19. Clearing rubbish from Brownfield areas is expensive 20. People may protest to Greenfield developments

People living in Portsea

Is the Gunwharf redevelopment sustainable?

Yes, It is sustainable because:• Mixed land use means that the space is used more often by

different groups of people• As Gunwharf is an outlet area it does not compete directly

with the shops in Commercial Road• Key worker housing and affordable housing have to be

provided as part of the development (e.g. No1 Gunwharf is 23% social housing)

• Generating tourist income for the city• Reusing a site and protecting listed and historic buildings• Is not out of town so is still easily accessible

But, it is Not sustainable where:• Entertainment and restaurants have caused the decline in the

Southsea Pier area, Odean cinema in North End, Port Solent

Brownfield + Greenfield

• Greenfield vs Brownfield Sites2.flv

Redevelopment of Portsmouth• New housing is always in demand in Portsmouth,

constant regeneration.• There are 2 possible sites: Horsea Island or

Waterlooville.

TASK:- Follow the task sheet to consider the advantages /

disadvantages of the two sites.- Use the OS map to help you, use evidence of existing

land-use & infrastructure- Make a decision about which site is best for

redevelopment & write a paragraph to explain why

Questions:

Many people are choosing to move out of city locations and into the countryside.

1. Identify 3 groups of people who support migration from urban to rural areas, and 3 groups who are

against this. Explain why each group feels the way they do.

2.Explain what is meant by the term ‘Green Belt’

3. What problems exist with Green Belts?

Half Term Homework: due 2nd March1) Mini-project. Find out about services in different

settlements. Compare what kinds of services (and how many) you find in different sized settlements. E.g. in what size settlement would you expect to find more specialist shops? What sorts of services are available in villages compared to cities?

2) Make a factfile / case study of a large retail centre (e.g. Trafford Centre, Bluewater, Lakeside, etc.). Include facts such as: range of shops / services, numbers of customers, how far people are prepared to travel (if you can find this).
