1) The major is Risk Management.
2) “Discuss the relevance of risk management to an NGO engaging in community development”) the response will probably look at two aspects: managing the risks that any organisation faces (i.e., Business Continuity Management) and managing the risks that this specific organisation faces (i.e., as an NGO engaging in community development). It’s important not to spend too much time (i.e., words!) on ‘general’ descriptions of NGOs, ‘development’, ‘risk’. Although you could take a case study approach, you will need to be careful that the essay doesn’t become overly descriptive; the focus of the essay needs to be on the why / what / how of risk management for an NGO engaging in community development.
