OUTLINE


• The African Monitoring of the Environment for Sustainable Development (AMESD) initiative makes use of Earth observation technologies and data to set-up operational environmental and climate monitoring applications in Africa

• Project funded through the European Development Fund

• The project is implemented under the coordination of the African Union Commission

• Timeframe for implementation: 2007-2013

OVERVIEW OF AMESD PROJECT


AMESD: GENERAL PURPOSE

• To improve decision making-processes in the fields of environmental management in Africa:

By increasing the information management capacity of African institutions

By facilitating access to Africa-wide environmental information derived from EO technologies

To allow “ Informed decision”

• Five Regional Thematic Actions (THEMA) have been established by the Regional Implementing Centers (RICs) to develop appropriate information services, in order to address the already prioritized decision needs of the Regional Economic Communities (RECs) (CEMAC, ECOWAS, IGAD, IOC and SADC )

AGRICULTURE SERVICE : AMESD SADC WORK PLAN

Principle: Improve and expand the current REWS systems from SADC. Automation and dissemination via EUMETcast

Allow agricultural remote sensing analysts: To perform Crop Condition Monitoring But also a view to forecasting yield and production scenarios

The Agricultural service Assist decision makers in answering the following questions:

What crops are where?What is the crop condition?What is the crop stage?

What is the likely yield?


AGRICULTURE SERVICE : AMESD SADC WORK PLAN

• Focus- data acquisition processing, analysis , bulletin and development of free and open-source technologies (toolbox)

• The Service comprises of a series of processing chains which are implemented using the Environment Station (E-STATION).

• The e-Station is an automated data production and data management system.• Three components (Acquisition, Processing Station & Analysis)

- Retrieve various data sources (EUMETCast, ftp,...)

- Automate and standardize data preparation tasks

- Automate data management

- Analysis ,facilitating in report writing and generation of time series graphs


OVERVIEW OF AGRICULTURAL PRODUCTS

• The agriculture service provides products which are intended to cover most of the information requirements of decision-makers and of the Institutions interested in crop monitoring and food security.

• The products of the Agriculture Service are also addressed to monitoring the environment and provide an early warning tool for possible hazards.

• There are 3 groups of products for the agric service

1) Baseline Products:

2) Products based on meteorological data from ground sources

3) Products based of Remote Sensing Data Sources


OVERVIEW OF AGRICULTURAL PRODUCTS

• Products based on meteorological data from ground sources and remote sensing products are provided in three forms:

• Monitoring Maps: describe and update the current climatic and vegetation conditions and are available regularly once every 10 days.

• Alarm Maps: identify, describe and label climatic and/or vegetation anomalies. These products are complementary to the Monitoring Maps.

• Graphs: based on crop masks & admin boundaries.


A) BASELINE PRODUCTS (3)

Agriculture Mask (JRC MARS -FoodSec Action)• It outlines those areas that are dedicated to

cultivation• Main use is extracting vegetation index

temporal profiles

Crop Statistics Map• Links the official crop statistic, presenting the

average production and planted area figures for each administrative region or unit.

Crop Specific Maps• Shows those areas where the major crops of

interest are mostly cultivated.

• Are maps and spatial documents which are at the origin of all the processing chains and act as background to most of all other products.

• Do not change in time or have a limited variability on a time scale of years.


B) PRODUCTS BASED ON METEOROLOGICAL DATA FROM GROUND SOURCES (20)

• Meteorological data from ground stations is complementary to remote sensing information.

• Main inputs: Rainfall and temperature.• Three orders of rainfall & temperature products are available:

1) Monitoring maps that update, on a decade scale, the evolution of the meteorological conditions

2) Alarm maps which highlight anomalies both in terms of current and cumulate rainfall values as well as temperature

3) Graphs which shows trends of rainfall and temperature• SOURCE:• GLOBAL SURFACE SUMMARY OF DAY (GSOD) data. • WGET- ftp://ftp.ncdc.noaa.gov/pub/data/gsod


Products based on meteorological data from ground sources

1) Monitoring maps

• Current Rainfall Map

• Cumulative Rainfall Map

• Current Temperature Map



2) Anomaly Maps

•Current Rainfall compared with the Long Term Average , Max and Min in terms of amount (mm)

•Current Rainfall compared with the Long Term Average, Max and Min as percentage (%)

•Current Temperature compared to with the Average, Maximum and minimum long term averages

•Cumulative Rainfall compared with LTA average, Max and Min (%).

•Cumulative Rainfall compared with LTA average, Max and Min (mm)



3) Graphs: Rainfall and temperature performance

•Rainfall events during the current season.

•Rainfall during the current season compared to the average, maximum and minimum long term trends

•Temperature trend during the current season compared to the average, maximum and minimum long term trends



Rainfall performance Graphs•Cumulative rainfall graphs for zones of interest


C ) PRODUCTS BASED OF REMOTE SENSING DATA SOURCES (18)

•Based on FEWSNET RFE, NDVI and DMP

•The products have exactly the same characteristics and follow the same processing line as the Meteorological products from ground stations

• Here too there are three orders of products: Monitoring maps, Alarm maps and graphs

1)Monitoring Maps (Rainfall)

•Meteorological Station networks offer best data, but are too sparse and report with delays. Satellite observations are an essential supplement to station observations

•Current Rainfall Estimates Map

•Cumulative rainfall map


C) Products based of Remote Sensing Data Sources: Rainfall

2) ANOMALY MAPS

•Current Rainfall compared with the Long Term Average (mm)

•Current Rainfall compared with the Long Term Average (%)

•Cumulative Rainfall compared with LTA average (%).


C) Products based of Remote Sensing Data Sources: Vegetation.

1) Monitoring Maps (Vegetation)• Current dry matter productivity .• Vegetation Index map• Cumulative dry matter productivity map

1) Anomaly Maps (Vegetation) Provides a qualitative indication of how ‘good’ or ‘bad’

the current season is when compared with other seasons or with the average situation.

• Vegetation Index Compared with average [difference]• Vegetation Index Compared with average [%]• Cumulative dry matter productivity compared with

average [%] raster map


Rainfall and vegetation graphs

Crop growing profile monitoring-reflect the crop condition through the crop growing season


C) Products based of Remote Sensing Data Sources

2) Crop Performance Indicators Maps•Current Water Requirements Satisfaction Index (WRSI) Map

•WRSI Anomaly maps

•Onset of Rains Maps

•Onset of Rains Anomaly Maps

•Soil Moisture Index Estimates


Support service:Long Range Forecast (LRF)

• The LRF service comes in as a support service to the agriculture service.• The products are operationally produced every month by SAWS.• Integration the LRF in the agric service will enable users embed a

“Seasonal Crop Outlook” in the bulletins and reports.• This will give an idea about the risk for crop failure at the end of the

growing season;• The LRF support service deliver the following 3 month forecasts:

1) “Rainfall”

2)“Minimum Temperature” and

3)“Maximum Temperature”.
