chapter 2.1

• • Development is the economic, social and political process which leads to an improvement of standard of living for a population.
• • Countries may be classified according to the level of development based on economic (Gross domestic product per capita) and social (life expectancy and adult literacy rate) indicators
• • Sustainable development meets the needs of the present population by achieving high standards of living for all
  • Key aims: economy, environment and society
• • Economic sustainability can be achieved by ensuring that a neighbourhood has a high enough population density, which helps support local businesses and keep transport and infrastructure costs low
• • Social sustainability can be achieved by ensuring that residents feel included and have a sense of shared identity. This can be fostered by having shared community spaces to promote regular social interactions 
• • Environmental sustainability can be achieved by ample protection for nature, having facilities that support waste minimisation and recycling and energy and water-efficient design approaches for buildings and landscapes
