Sub-regional Environmental Monitoring and
Information System Phase II [SEMIS-II]
Abhijit Patil
UNEP RRC.AP, Bangkok
Background
 Following up from achievements of SEMIS I and
recognizing the need for follow-up support;
 SEMIS I achievements: Core datasets; conceptual
database design; technical capacity for data exchange
Regional Resource Centre
for Asia and the Pacific (UNEP RRC.AP)
 Considering the request by Greater Mekong Subregion (GMS-WGE-4) in Mar ’98, and endorsement by
ministerial meeting in Sep’98, ADB approved SEMISII in Dec ’99
…to help GMS governments to make informed
decisions regarding sustainable development through
Integrated Economic and Environmental
Development Planning
Regional Resource Centre
for Asia and the Pacific (UNEP RRC.AP)
Objectives

Assess the availability of useful and relevant data for planning
purposes;

Increase and strengthen the capacity of the national Governments
to collect and process the information/data;

Increase the capacity of national Governments to make informed
decisions regarding development investments relating to
sustainable utilization of natural resources;

Enhance the ability of GMS national Governments to conduct
integrated economic and environmental planning with relevant
data; and

Conduct, store, manipulate, and share actual integrated planning
information using the data collected in pilot projects for some
“Hotspot” areas, such as those identified in TA 5783--REG: SEFGMS.

Early Warning Information Systems (EWIS)
It is product of the SEMIS I project, which involves a
fairly complete database of important GIS layers like
Environment (Forest, Rivers, Wetlands etc.)
Demographic data (Population, Poverty etc.)
Infrastructure (Road, Dams etc.)
Regional Resource Centre
for Asia and the Pacific (UNEP RRC.AP)
and some other ancillary information (layers)
The data is provided in different scales (1:1M, 1:5M and
1:250K) depending on the layer and the source. The data was
generated by UNEP RRC.AP along with the help of MRC,
WWF and other international agencies. The national agencies
were the major source for the local data layers.
Additional Data
The additional to the core data layers followings are identified
Hydrological layers “part of topography, important for
planning, normally use independently, should be collected”,
(Topo and Hydro data layers can be derived independently
using modern technology)
Regional Resource Centre
for Asia and the Pacific (UNEP RRC.AP)
Digital imagery “digitized air photos, digital orthoimagery,
satellite imagery etc.” (Landsat 7ETM+ is one of the
solutions)
Scanned paper map “Reproduce the map, head-up
digitizing, easy to georeferenced” (original maps can be
scanned and save as raster format and use for multi
purposes)
Additional Data
The additional to the core data layers… (cont;)
Regional Resource Centre
for Asia and the Pacific (UNEP RRC.AP)
Slope and aspect data layers “critical to some applications
such as erosion, Crop selection etc.”, (not difficult to
generate from elevation data, but useful for those who can
not do for themselves)
Water Quality Data “.pH, conductivity, chemical analysis
are proposed to be measured” (depth to groundwater,
surface water hydrology, basin delineation, subsurface flow
etc are useful for analysis of the impact of the potential
projects)
