This question allows you to demonstrate your understanding of both geography as a discipline as well as global health. Your thesis outlines the ways in which a geographical perspective is beneficial to the study of global health and, in doing so, states the structure of your essay. Start by choosing what the key features of a geographical perspective are, for example space and place, scale, and environment - these can then be used to create a structure. (Mastering these concepts will be useful throughout your degree). For each point, provide a definition and consolidate how this furthers knowledge of global health. For example, ‘Geography’s focus on the environment as the interaction between humans and their natural surroundings brings to light how health status is determined by the intersection of complex social and biological phenomena, further highlighting its spatially contingent nature’. Make sure to use examples throughout to strengthen your arguments. You may want to add a historical overview of how geographies of global health have developed to consolidate your understanding. To end your essay with a strong conclusion, you can discuss further implications such as relevance to policy and development efforts.
