This Farmers' Agribusiness training course has been developed to help both farmers and farmer organisations. Its intention is to provide access to provide access to additional skills and knowledge that will allow farmers to move from a 'farm' to a 'firm'. This lesson continues on from lesson 3 and should be seen as a continuation. You will need to review lesson 3 and the discussion on Economic versus Accounting Costs & Relevant Cost Analysis. In lesson 4, however, we will focus on Revenues & Measurement of Profitability and Risk & Uncertainty.
