2. 3. How does urbanisation change places?

2.1. Reduced biodiversity.

2.2. Urbanisation causes massive growth within urban areas.

2.3. Environmental degradation (e.g deforestation) to make room for factories and residential buildings.

2.4. Modifies hydrologic and biogeochemical cycles.

2.5. Loss of arable/productive farmland.

2.6. Increase in economical and agricultural activity,

2.9.1. Population and Rural Growth from 1950 to predicted 2050 Though only being around 250 million in 1950, the graph shows a consistent growth from 1950-2010. After that, the prediction shows that the growth continues on its current trend of a consistent growth.

4. 4. What strategies are used to manage environmental change in urban places to enhance urban stability?

4.1. Research and set priorities on issues that are the most important. There's no better strategy than strategising, itself.

4.2. Managing land degradation.

4.2.1. Introducing chemicals to improve soil structure.

4.2.2. Re-establishing ground cover.

4.2.3. Controlling wildlife population (e.g pest eradication programs)

4.3. Managing soil salinity.

4.3.1. Education programs and re-vegetation programs.

4.3.2. Making active decisions regarding salinity, such as salt intervention schemes.

4.4. Managing invasive species (pests).
