A review of GIS and
Remote Sensing Practices in
MNRE, Samoa
Ministry of Natural Resources and
Environment
Pacific GIS & RS Conference Suva, Fiji 26th November – 1st December, 2018
VisionImproved quality of life for all Samoans that is premised on sustainable development and management of the country's
natural resources and environment.
Organizational Structure
(Insert organizational structure and highlighted selected divisions for the workshop/trip)
Spatial Information Agency (SIA)
Objectives;a) to support the effective and efficient use and sharing of
spatial information; b) to produce and maintain national coverage of topographic
maps, marine charts and other remote sensed imagery needed for the sustainable management of land, sea and other natural resources;
c) to protect Government’s interests in all matters of intellectual property and copyright concerning the production, supply and ownership of spatial databases and spatial information products and published material.
d) …etc…

Use GIS applications in Forest Management
• Monitoring Forest Change (deforestation and forest degradation)
• Managing Forestry Asset Information - eg forest plantations, trails, roads, buildings etc
• Planning Forestry Activities - eg logging, forest restoration, replanting after cyclones, weed management, village woodlots, new national parks.

Analysis
Eg Forest Cover Change (ABT 5)- State/Impact Indicator-
Maps are useful to show spatial distribution of forest cover and change over time
Analysis shows that the forest cover decreased by 1.7% from 1999 to 2013 (a reduction in forest cover from 60% to 58.3% of the land area of the country)

1987 Forest Cover

2013 Forest Cover
1999-2013 Forest CoverChange
Biodiversity management and conservation Area covered with invasive species (ABT 9)- State/Impact Indicator-
Analysis shows that the area dominated by invasive trees increased by 1.4% between 1999 and 2013

Use of GIS on Water resources management and development
Watershed characterization for the development of watershed management plan
Generation of prioritization maps for the implementation of conservation activities and measure
Monitoring of conservation and management operations through maps like (tree planting coverage, hydrometric network, Licensing of Water abstraction etc)

P3DM
• P3DM is a community engagement tool which integratesspatial data with local “traditional knowledge” and usedwidely for spacial planning, climate change adaptation,Disaster Risk Reduction etc.
• P3DM is a product of GIS data, it uses GIS technology tobuild model from series of contour lines and importantsource of information to enter into GIS for participatoryplanning and implementation.
• P3DM is used widely in the Pacific in Fiji, Solomon Islands,PNG, Samoa ,Tonga, Nauru and now Cook Island.
