10 Remote sensing SANSA: Earth observation ARC: Coarse Resolution Satellite Image Database (CRID) as a national asset, containing imagery from four course resolution satellites (MODIS, NOAA AVHRR, and SPOT VEG: & Meteosat). Through VGT4AFRICA and GEOSUCCESS projects, disseminate vegetation information via GEOcast SAWS: EUMET sats MSG 10

11 11 Modelling Refer Singels et al., (2010): Modelling crop growth and crop water relations in South Africa: Past achievements and lessons for the future SAWS (Agrometeorology): ACRU: a multi-purpose agrohydrological model that integrates the various water budgeting components of the terrestrial hydrological system. Been used in a range of agriculture and water resource assessments in e.g., South Africa AquaCrop crop water productivity model BEWAB: An irrigation water management program UFS Southern Africa Limited Area Model (LAM): UK Met Office- Unified Model (UM) output for Africa South of the equator in a 12 x 12 km spatial resolution, 3 hour temporal resolution for a 48 hour Forecasting period.

12 Information dissemination 12 Daily extreme weather warnings issued to the sector with relevant strategies attached (as and when available from SAWS). A monthly National Agrometeorological Committee (NAC) Advisory document is compiled and disseminated to the sector. It contains: Rainfall maps of recent months, NDVI map of the past month, Conditions in the provinces i.e. crops, livestock, grazing, pests and diseases, disasters, SADC information FEWS NET, Markets, Seasonal forecast SAWS Strategies, i.e. strategies for crops, livestock and hazards,

13 13 Information dissemination Awareness campaigns: farmers days, study groups for farmers, capacity building workshops, including the roving seminars on weather and climate adopted from the Commission of Agricultural Meteorology WMO. Broadcasting: s Organised Agriculture Extension Officials, Disaster Risk Management officials Awareness campaigns Departmental websites (national and provincial), Departmental offices Media Tribal authorities and Multipurpose centres (Thusong Centres)

14 14 Information dissemination Users: Farmers Industry users i.e. Agri- banks, insurance etc. Disaster risk management Other government departments Scientific organisations.

15 15 Improvement Shorter time scale information for bi-weekly bulletins. Downscaled/area specific agromet information.
