This report presents the results of economic analyses of recently completed projects within RIRDC’s Global Challenges R&D Program. The primary purpose of this report is to provide input to the RIRDC evaluation policy. Specific objectives were to ascertain if, and to what extent, benefits have accrued from investment in the Global Challenges R&D Program. This will inform RIRDC management regarding Program performance. Another objective of the economic analyses is to contribute to the process being undertaken by the CRRDC that aims to demonstrate through examples the outcomes and benefits that have emerged or are likely to emerge from the 15 Rural Research and Development Corporations (RDCs). Valuation of these benefits, along with identification of investment expenditure, is required in order to demonstrate the RDCs’ contribution to Australian rural industry as well as environmental and social benefits to Australia. The Australian Government is particularly interested in such contributions in order to be assured that public funding of R&D is justified.
