Abstract:
The Central Fragile Area (CFA) is the most environmental sensitive region in Sri
Lanka. It has huge strengths and potentials that can be utilized for future development
of the country. The region is experiencing various development issues due to over
exploitation of its resources over the years. This has created a mismatch between the
environmental conservation and economic development in the region. Therefore, it
needs to rearrange current spatial development patterns of the CFA. In line with these
trends, this research carried out to develop a spatially integrated planning approach for
sustainable development of the CFA. Accordingly, the research developed a spatially
integrated environmental sensitivity index (SIESI) based on four case study areas
namely Walapane, Ratnapura, Gangawatakorale and Kandy Four Gravets and
Palindanuwara DSDs. A questionnaire survey carried out with 170 participants using the
non probability sampling method to collected primary data. The SIESI included 11
variables 38 indicators that were identified based on the secondary data. The Analytic
Hierarchy Process (AHP) technique, the inputs and ranking values from selected
experts applied to assign weights for these variables and indicators. The results
obtained using the ArcGIS Weighted Overlay Analysis. Results indicated five
environmental sensitivity levels such as very high, high, moderate, low and very low in
the case study areas of the CFA. Based on the environmental sensitivity levels, author
proposed four spatial development areas; (1) conservation areas (2) conservation based
agricultural areas (3) Agriculture based rural areas and (4) urban and rural settlement
areas for case study areas. Author also proposed a set of viable development strategies
such as establishment of protected area network, implementation of the national
physical planning policy, integration of environmental conservation and economic
development, mainstreaming disaster risk reduction and disaster resilient initiatives into
development activities etc. to create a balanced development between the
environmental conservation and the economic development in the CFA. This is the first
attempt of developing a spatially integrated environmental sensitivity index to identify
environmental sensitive levels in Sri Lanka. Research provides a scientific and
acceptable planning tool for geographers, planners, academics, politicians, policy
makers and developers to develop the CFA in a sustainable manner. It is possible to
apply the developed SIESI to address similar environmental sensitivity fragile areas in
other countries also.
