Geography Unit 4: Global perspectives


This unit investigates the geographic characteristics of global phenomena and responses to them. Global phenomena are major natural or human events, processes or activities. Such phenomena are distributed globally and possess the capacity to affect the globe or significant parts of the globe and require more than a local or national response.

Human population studies are significant to understanding the challenges facing our globalised world. Spatial variations in the distribution, composition and growth of human populations are related to the nature of places. A global perspective is a viewpoint or policy designed to guide future action by people or organisations to address the effects of global phenomena. Phenomena such as El Nino, migration, rapid communications technology, Earthquake damage, genetically modified crops or globally changing patterns of investment and industrialisation, shared ocean and atmosphere resources, pandemics and other ‘borderless’ phenomena play important roles in shaping community, environments and landscape change.

Governments, organisations, groups and individuals respond to global phenomena in different ways. The type of response is affected by social, economic, historical and political considerations, resource access and distribution, and the nature and scale of the event or process. Policy developed to deal with a global phenomena and its effects results in the formation of a global perspective. This unit investigates the distribution patterns of selected global phenomena. It considers the causes, dimensions and impact of global changes and analyses policies and strategies, including those that promote sustainability, to enable a better world in the future.

Students must investigate two global phenomena in each area of study, one of which must be human population.
