This web portal has been developed as a key output of a collaborative project
carried out by the International Water Management Institute (IWMI)
for enhanced disaster preparedness and rapid response for droughts and other
natural disasters in Sri Lanka. The project was funded by Unilever Sri
Lanka Limited as part of its commitment to sustaining water
resources in Sri Lanka.

The overarching goal of this web portal will be to establish a comprehensive
national Knowledge Base System for Sri Lanka (KBS-Lanka) that encompasses
disaster preparedness and rapid response for droughts and other natural
disasters, and also enables natural resource assessment and monitoring on a
near-real-time basis using remote sensing and other spatial techniques. The
KBS-Lanka project has developed a near-real-time (fortnightly and/or monthly)
system on the following 3 key components using satellite sensor data from
advanced systems that are available free, from reliable sources:
-
Baseline conditions (BC-Lanka): Each area will be enriched
with numerous baseline datasets (e.g., soil types, land use pattern, drainage,
road network, hydro meteorological stations, etc) on the lines of
http://www.iwmidsp.org. This data will be invaluable for rapid response and for
scientific analysis of a situation or a problem.
-
Crop monitoring and Water Productivity patterns (CMS-Lanka):
First a baseline data set of cropped areas and crop type will be mapped using
high resolution satellite imagery. This will be followed by seasonal and/or
annual crop assessments (e.g., % area cultivated relative to average area
cultivated over last 5-years; change in crop types, change in crop calendar).
-
Drought Monitoring System (DMS-Lanka): This is based on Remote
Sensed data from advanced MODIS sensor and historical AVHRR sensor. The final
product is a near-real-time online drought monitoring system that will allow
drought and extreme wet conditions in different parts of the country to be
detected and reported every fortnight. The methodology will be similar to the
one used for DMS for South Asia (dms.iwmi.org), but most likely with an
advanced on-line interface.
This web portal is an online operational remote sensed and GIS based knowledge
base system (KBS-Lanka) from smallest administrative unit (e.g., Grama
Nilhadari) to the largest administrative unit (e.g., river basin or Country).
Currently, in the first phase, KBS-Lanka is developed for IWMI’s Ruhuna
Benchmark Basins (comprising Walawa, Kirindi and Menik basins) as proof of
concept and during phase II will be developed to cover the whole island as
links and partnerships develop with the Government, the main client. Phase I
will include a substantial research component in developing the methodology
while phase II will focus on building up the systems and the database.
The web portal provides a remote sensed and GIS based integrated information
system and establishes a working methodology to effectively use this
information, and to develop an online dissemination service to reduce
vulnerability issues and minimize adverse effects on the population in disaster
situations. We have also emphasized on a wide range of natural resources
secondary data fed in, to develop a comprehensive baseline database on natural
resources. All KBS-Lanka data and products are made freely accessible for
downloadable from anywhere in the World.
