United Nations/Pakistan International Workshop on Integrated Use of Space Technologies for Food and Water Security Islamabad- Pakistan 11 - 15 March, 2013 Food Security Monitoring Using Space Technologies in Sudan Enaas Ismail Abdalla Ministry of Agriculture and Irrigation Sudan
The programme started with the signing of a memorandum of understanding between the Ministry of agriculture and EFTAS to help create a more accurate identifying and estimating cultivated area in traditional sector. the program contributed significantly to agricultural seasons monitoring with good contribution in raising awareness and disseminating a culture of using remote sensing technologies which absent from ministry to end American aid project by the end of the 1980s.
GLOBAL L MONITOR TORIN ING G FOR FOOD SECURIT ITY Global Monitoring for Food Security • ESA GMES Service Element (GSE) • User driven Services at different scales: Continental products National products • History : 2003-2004: Startup, consolidation & definition 2005-2009: Implementation, Up-scaling 2010-2013: Transfer to Operationability
Encourage partnerships in monitoring Food Security. • Contribute Earth Observation technologies to improve • Food Security. Support existing frameworks through: • • Sharing of expertise & knowledge. • Developing, testing and providing operational FS monitoring services. Provide advanced crop information derived from Earth • Observation data.
It’s come with the following objectives: Consolidation of Process Chain in different production schemes and agro ecological zones. Generation of operational products. Know how transfer.
For Sudan two main GMFS3 Products are agreed in a Memorandum of Understanding: Agricultural Monitoring service type and are executed by EFTAS Agricultural Mapping (AM) product. Support to the optimisation of agricultural survey (ASO) product.
inter-seasonal indicative map of vegetation growth activities based on Medium Resolution imagery Indicative fAPAR Extent of vegetation Growth (EoG-fAPAR_SDN). cultivated area maps Cultivated Area product based HR data.
provide an early indicative inter seasonal map upon the recent spatial distribution of vegetation growth to FMoAI before the harvest. Facilitate assessment of the spatial crop development and distribution within the given growing season.

The Me dium R esolution I maging S pectrometer (MERIS) is a payload component of Envisat-1. Data are acquired at 300 m thus vegetation can be monitored at regional to global scales. After failure of ENVISAT Satellite the project switch to d ata Sets for MODIS/Terra+Aqua Leaf Area Index/FPAR 8-Day L3 Global 1km
based on Medium Resolution MODIS imagery. The Indicative fPAR Extension of vegetation Growth product intends to provide as early as possible an indicative inter-seasonal map upon growth activities. It reflects the fraction of the solar energy which is absorbed by the vegetation within each pixel. ( Fraction of Photosynthetically Active Radiation ) FPAR measures the proportion of available radiation in the photosynthetically active wavelengths that are absorbed by green vegetation. It’s a biophysical variable directly correlated with the primary productivity of the vegetation and is captured from MODIS/Terra+Aqua sensor.
The outcome of the processing chain is a GeoTIFF describing the fraction of the solar energy which is absorbed by the vegetation within each pixel. The given values do range between 0 and 1 and reflect the percentage of absorbed solar radiation by the actual natural and agricultural vegetation. These values are reflecting the actual distribution and intensity of plant growth and do indicate the potential extension of traditional rain fed agriculture within the given time span.
