11. According to CAS 8.2.6 -SDS related issues Three major things needed in the near future (1-2 years)

12. 1) To approve the recommendation to formally designate the SDS-WAS regional node in Beijing, China, as another RSMC-ADSF for the region consisting of Asia and the Central Pacific. New web portal of Future Asian RSMC-ADSF http://eng.weather.gov.cn/dust/product/8001.html#

13. Research Operational forecasts SDS-WAS 2) to produce and deliver atmospheric sand and dust storm forecasts after the evaluation of dust prediction models to address concerns expressed at CBS-15 and report on it to the CAS Management Group (MG) leading by a Joint CBS-CAS Task Team on Atmospheric Sand and Dust Storm Forecasts Future

14. 3) to establish an SDS-WAS Steering Committee for global research coordination of regional activities, supported by a trust fund is the need to do as soon as possible

15. Long term

16. 4) encourages the efforts to increase the observational capacity, and to support regular training events aimed to encourage and facilitate the use of the products supplied by the SDS-WAS. CMA in Mongolia

17. 5) Encourage in possible future to establish the Pan American and West Asia Centers • 6) Encourage to carry out capacity building activities of dust forecasting systems and on development of dust products from remote sensing observations specially focused to developing countries in Africa and Asia severely affected by dust storms.
