Food and Water Security Islamabad- Pakistan 11 - 15 March, 2013 - - PowerPoint PPT Presentation

United Nations/Pakistan International Workshop

• n 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.

• f 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.

no active vegetation sparse active vegetation much active vegetation

The Medium Resolution Imaging Spectrometer (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 data 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

• f traditional rain fed agriculture within the

given time span.
