Under the supervision of the statistician, the consultant is expected to produce the following tangible outputs, which will be assessed based on their quality and timely completion: • Work-plan that includes a timeline for key deliverables. • Critical review of capacity building materials and relevant literature. • Practical methodological guidelines on measuring crime-related IFFs (approximately 60-80 pages). At a minimum, the guidelines should cover: a) Introduction to IFFs and the relevance of measuring these flows. b) General overview of the UNODC/UNCTAD conceptual framework for the statistical measurement of IFFs focusing on crime-related IFFs and explaining the main concepts in user-friendly language. c) Measuring crime-related IFFs (drug trafficking, smuggling of migrants, wildlife trafficking and trafficking in persons). For each, a discussion on: - Main concepts. - Methodology for estimating market values and associated IFFs. - Key data and their availability (data sources). d) Common challenges and limitations. e) Discussion on the income management phase of crime-related IFFs (i.e., where does the money go and how). f) Further work and research agenda. - Improving methodological approaches for estimating crime-related IFFs - Improving data collection/sharing mechanisms. - Strengthening institutional capacity and technical assistance. • Improved data availability assessment and data collection tools.
