Markscheme

There are a number of possibilities, including air pollution, visible as an atmospheric haze creating poor visibility in the distance, vehicle noise and congestion.

a.

A narrow sky view area restricts sunshine, a high density of buildings retains heat, tall buildings reduce general wind speed, but may focus winds, producing a canyon effect with higher wind gusts. The characteristics must be visible in the photo; a general explanation of the urban heat island is not acceptable.

b.

Candidates may choose to either agree or disagree with the question, but stronger answers accessing bands E and F must address both sides of the argument. A good answer accessing band D and above must have case study support and is likely to refer not only to environmental, but also to social and/or economic aspects of management or mismanagement.

Environment: resource conservation, waste management, transport.

Social: housing, educational opportunities, political freedoms and equal opportunities, and local involvement in decision-making.

Economic: income security and employment diversity.

Marks should be allocated according to the markbands.
