SUMMARY OF CONCLUSIONS OF OC AT ITS 2ND REG.SESS.
Peter Leslie of the United Nations Development Programme (UNDP), as Secretary of CCAQ(FB) for a further period of two years, from 1 January 1998 to 31 December 1999. 44. (...) Report of the eighty-seventh session of CCAQ(FB), United Nations Headquarters, New York, 25 to 29 August 1997 45. OC noted that the report of the eighty-seventh session of the CCAQ(FB) had identified a number of issues to be brought to the attention of ACC, and considered that those issues could be addressed, on behalf of ACC, by the high-level meeting of CCAQ referred to in paragraph 20 above.

The technical assistance is based on an application tool which incorporates the new revised methodology for the compilation, imputation and validation of the Food Balance Sheets (FBS) recently developed by the FAO Statistics Division. Support can be provided through regional and national-level capacity development activities and includes: Assessment of the FBS national capacity and data availability; Establishment of a Technical Working Group (TWG) composed of key national data providers and users/analysts; Highlighting of the links between some FBS variables and the Sustainable Development Goals (SDGs), i.e. SDG 2.1.1 on Prevalence of Undernourishment; SDG 12.3.1 on Global Food Loss Index; SDG 3.5.2 on  healthy consumption; Technical training on the FAO FBS methodology, overview of the newly developed FBS modules and imputation methodologies; Practical exercises on the computation of the SUA/FBS; Design and compilation of the national SUA/FBS using the new FBS country compilation tool (R based Shiny app); Review and analysis of the finalized national SUA/FBS and of the main results; and Calculation of some key indicators, such as the import dependency ratio and the self-sufficiency ratio, and draft of a final report.
