USING GIS TO MAP AGRICULTURE POTENCY
IN TIMOR TENGAH SELATAN WEST TIMOR

Research Objective
The research on Agriculture Potency and Mapping
of Land Use Suitability in Timor Tengah Selatan
(TTS) has the purpose to assess and map the
available agricultural resources and is aimed at
providing a managerial tool for the decision makers
and the prominent figures in developmental
activities, in bringing the benefits of agricultural
resources precisely and appropriately, both in
recovering food security condition and improving the
prosperity of the community, which 90.2% of them
are farmers (Susenas, 2000).
Research Methodology
The assessment on agriculture potency and
mapping of agricultural land suitability is conducted
through 2-way approaches:
• Compare the requirements needed for a certain
use with the characteristics of the resources in the
land (objective approach)
• Assess from inside out, i.e. observe the real
agricultural characteristics and potency based on
the subjective opinions from the members of the
community
Primary Variables
• Climatic Factors
• Water availability and water shortage conditions
• Land capability on the bases of land
characteristics, fertility, and limiting factors in soil
tillage, and
• Types, area grouping, and agricultural
commodities production.
Other Non-Technical Variables
• Priority of plants to work on or develop according
to the community,
• Economic values of agricultural commodities,
• Technology input factors,
• Marketing aspects,
• Human resources potency,
• Market condition and availability,
• Financial institution, and
• Area accessibility, especially the condition of
transportation means and infrastructures
Using GIS to Mapping:
(a) Land Unit System
(b) Level of Availability of Nitrogen, Phosphorus,
Potassium and Organic Matter
(c) The Limiting Factor of Soil Tillage
(d) The Availability of Water
(e) Distribution Map of Priory and
the Pattern of Agricultural Activities
(f) Land Use Suitability
