DROUGHT MONITORING CENTRE-NAIROBI FOR THE GREATER HORN OF AFRICA(GHA)
BACKGROUND AND HISTORY
The Horn of Africa, like many other parts of the tropics,
are prone to extreme climate events such as droughts and floods. These extreme
events have severe negative impacts on key socio-economic sectors of all
the countries in the sub-region.
In an effort to minimise the negative impacts of extreme climate events and
take advantage of the good years, 24 countries in the eastern and southern
African sub-region under the auspices of WMO and UNDP established a regional
Drought Monitoring Centre (DMC) in Nairobi and a sub-centre in Harare in
1989.
The main objective of the DMC was to contribute to monitoring, prediction,
early warning and mitigation of adverse impacts of extreme climatic events
on agricultural production and food security, water resources, energy, and
health among other socio-economic sectors. Since the establishment of DMC
in 1989, the centre has played an important and useful role in providing
the sub-region with weather and climate advisories and more importantly,
timely advance warnings on droughts, floods and other extreme climate related
events.
At the end of the UNDP funded Project in 1998 and due to the increased demand
for climate information and prediction services, the Nairobi and Harare components
now operate independently and are referred to as the Drought Monitoring Centre,
Nairobi (DMCN) and the Drought Monitoring Centre, Harare (DMCH). DMCN caters
for countries in IGAD and other countries in the Horn of Africa region, while
DMCH is responsible for countries in southern Africa.
The 8th Summit of the Heads of State and Government that was held in Khartoum
in November 2000 adopted DMC as a specialised institution of IGAD.
COMPONENTS OF THE DMCN:
- Data Processing
- Climate Monitoring
- Climate Prediction and early warning
- Capacity building and research
- Climate Applications
- Climate outlook forums for enhanced
- interactions between climate experts and sectoral users of climate
Informations and Prediction servises.
The participating countries are:-
Burundi, Djibouti, Ethiopia, Eritrea, Kenya, Rwanda,
Somalia, Sudan, Tanzania, and Uganda,
OBJECTIVES OF THE DMCN
The best strategies to minimize negative impacts associated with the climate
extremes are enhanced monitoring and timely availability of weather and climate
information and prediction products, together with the availability of effective
disaster preparedness policies.
The main mission of the current DMCN is timely climate Informatin
and prediction services and enhanced Applications of such products in order
to reduce climate and weather related risks to food security, water resources
and health for sustainable development in the Greater Horn of Africa”.
OPERATIONAL ACTIVITIES:
- Development of regional and national quality controlled databanks.
- Data processing including development of basic climatological
statistics.
- Timely acquisition of near real time climate and remotely sensed data.
- Monitoring space-time evolutions of weather and climate extremes
over the region.
- Capacity Building in Climate Monitoring, modelling and Prediction
Services.
- Delineation of risk zones of the extreme climate related events.
- Enhanced networking with the NMHSs and regional and international
centres for data and information exchange.
- Assessment of the impacts of the extreme conditions of various
socio-economic activities.
- Timely dissemination of early warning products.
- Public awareness and education of users of meteorological products.
- Conduct capacity building activities.
- Development of the users climate applications, pilot projects.
- Organization of Climate Outlook Forums for the Greater Horn
of Africa countries.
- Enhancement of interactions with users through regional and
national users workshops, application projects, etc.
ABOUT DMCN PRODUCTS
Ten day (dekadal) weather advisories:
- Dekadal climatological summary of rainfall and drought severity.
- Dekadal socio-economic conditions and impacts.
- Dekadal synoptic review and weather outlook.
Monthly and seasonal products:
- Monthly and three monthly climatological summaries and drought
severity.
- Three months (seasonal) weather outlook.
- Socio-economic conditions and impacts.
These products are disseminated to all national meteorological and hydrological
services of the participating countries to serve as early warning information
to a variety of sectoral users of meteorological information and products
including policy makers, planners, health, energy, agricultural and water
resource sectors, farmers as well as research institutions among others.
Modes of Data and Products Exchange:
- High Frequency Radio Fascimile.
- Meteorological Data Distribution (MDD) System.
- Fax
- Internet (See Web Site)
- Users’workshops
- Bulletins
- Climate Outlook
Data used:
- Historical data archive
- Near real time climate data from participating countries.
- Numerical weather prediction products from advanced Global Climate
Centres.
- Re-analyses data, and Global circulation products such as wind,
pressure and Global Sea Surface Temperature Anomalies including the El-Niño/Southern
Oscillation (ENSO) conditions.
- Vegetation Conditions from satellite and satelite
derived products.
Major Achievements:
- Creation of a climate data bank that is constantly updated.
- Capacity building in data processing, climate monitoring &
modelling, and prediction.
- Upgrading of DMCN computing facilties.
- Uninterrupted and timely production and dissemination of early
warning information.
- Enhanced collaboration between NMHSs of the participating countries
especially in the area of data exchange.
- Collaboration between DMCN and advanced regional diagnostics
centres e.g. IRI has been enhanced especially with regard to climate modelling
and prediction capabilities.
- Climate capacity building workshops, Capacity building users’
workshops and climate outlook forums have been successfully held.
- Enhanced capacity of NMHSs in statistical modelling for diagnostic
analysis and prediction.
- Enhanced computing capacity of the NMHSs.
- Close collaboration between climate scientists and users of
climate information has been fostered.
- Pilot application projects have been initiated with some sectoral
users with the support of NOAA/OGP.
- Improved regional climate modelling capacity is being undertaken
through collaboration with IRI.
- Institutional framework:- DMCN has been a project since inception.
The 8th IGAD summit held in Khartoum, Sudan in November 2000, established
the DMCN as a specialized Institution of IGAD.
