A broader survey that counts sites and site population can then be used to scale the detailed surveys up to the national level. The goal should be to produce a mercury use estimate with an accuracy of +/- 30% and at worst +/- 50%. This level of confidence should be obtainable with a moderate level of effort, time and financial resources, yet should be good enough to inform the NAP and allow priority actions to be decided. The baseline estimate provides a first estimation upon which to measure progress in reducing mercury use through mercury reduction programs and interventions as obligated under the Minamata Convention. The same methodology should be repeated to evaluate the effectiveness of interventions, and in particular the same sites that were studied in detail to create the baseline should be used to again to measure progress in reducing use. Doing so will increase the confidence in the monitoring results. 5.5 Strategies for Reducing Emissions, Releases, and Risks of Exposure Paragraph 1(b) of Annex C of the Convention requires countries to include in the NAP the actions to eliminate the practices” in ASGM, as priority measures. Paragraph 1(e) requires that, in “worst addition, countries must include in the NAP strategies to promote the reduction of emissions, releases and exposure. There is no one technical solution for eliminating mercury use in ASGM that will work in all geological, social and cultural settings. Therefore strategies should be based on a sound understanding of conditions in the country (see Chapter 5.4) and can include immediate and long-term strategies.
