Short description of the best practice

Arc Gis is a new gis mapping pakage.  full picture of mapping information in Tonga and all characteristics as far as resources are concerned could be applied. for example most vulnerable areas for drought could be identified using this arc gis.

Location

the whole of Tonga island

If the location has well defined boundaries, specify its extension in hectares:

649.0

Estimated population living in the location:

100000.0

Brief description of the natural environment within the specified location.

mainly volcanic ash from 20,000-50,000 years old.  soil type determine by younger ash in different locations.|
mostly flat except for high island in the northern parts of Tonga.  few volcanic islands with height of 30m.  1m high mostly experience by the rest of Tonga
tropic with mean temperature of 25 degree celcius.  summer and winter seasons.  wettest months January and February.  Mean annual rainfall 1800mm. trade wind is south easterly wind.  

Prevailing socio-economic conditions of those living in the location and/or nearby

this is for the whole of tonga.  from the king to the poorest person in Tonga
lands belongs to estate - king, nobles, and government.  people may request for land from the 3 three estates mention above.  people can register land include lease.  |
government and farmers, fishermen|

On the basis of which criteria and/or indicator(s) (not related to The Strategy) the proposed practice and corresponding technology has been considered as 'best'?

new technology

Main problems addressed by the best practice

maintenance of the equipment
purchasing equipment

Outline specific land degradation problems addressed by the best practice

identification of drought areas, eroded sites and areas with low soil fertility

Specify the objectives of the best practice

Build comprehensive GEOsource for TOnga
develop strong institutional cooperation to improve understanding and managementof hazards, land and offshore resources and environment|

Brief description of main activities, by objective

control points and bench mark
high resolution digital elevation model
coastal bathymetry
land parcels
infrastrucutre data
arc gis taining
survey training using GPS and total station

Short description and technical specifications of the technology

GEO Source Tonga is a GIS Base topographical mapping system that uses the new GPS-based geodetic datum and survey coordinates
Arc GIS

Was the technology developed in partnership?

Ja

List the partners:

Beca international
GNS Science Limited

Specify the framework within which the technology was promoted

• International initiative

Was the participation of local stakeholders, including CSOs, fostered in the development of the technology?

Ja

List local stakeholders involved:

Private Sectors in engineering and mapping work

For the stakeholders listed above, specify their role in the design, introduction, use and maintenance of the technology, if any.

capacity development with the introduction of the technology
training with the usuage of the technology

Was the population living in the location and/or nearby involved in the development of the technology?

Nee

Describe on-site impacts (the major two impacts by category)

easier access to quality map of tax and town allotment
easier production of maps using the new technology
cheaper
accuracy and timely with the production of maps
environmental vulnerable areas determine and access.  forest coverage, coastal mapping for erosion, climate change vulnerability sites|
topography

Describe the major two off-site (i.e. not occurring in the location but in the surrounding areas) impacts

this program for the whole of Tonga.  project could impact the whole of the country

Impact on biodiversity and climate change

Explain the reasons:

put vulnerable climate change site of the map
forest coverage
tree planting areas
mapping of biodiversity coverage such as forest coverage, national parks and resrves, marine reserves, SMA
rare species on map |
identify vulnerable sites and identify adaptation measures
coastal erosion and adaptation option identification

Has a cost-benefit analysis been carried out?

Has a cost-benefit analysis been carried out?

Nee

Was the technology disseminated/introduced to other locations?

Was the technology disseminated/introduced to other locations?

Nee

Were incentives to facilitate the take up of the technology provided?

Were incentives to facilitate the take up of the technology provided?

Ja

Specify which type of incentives:

• Financial incentives (for example, preferential rates, State aid, subsidies, cash grants, loan guarantees, etc)
• Fiscal incentives (for example, exemption from or reduction of taxes, duties, fees, etc)

Can you identify the three main conditions that led to the success of the presented best practice/technology?

highly motivated team of experts and project management unit.
replicable elsewhere with some level of adaptation
user friendly program
highly motivated local government and private sector

Replicability

In your opinion, the best practice/technology you have proposed can be replicated, although with some level of adaptation, elsewhere?

Ja

At which level?
