甲Abstract of Dissertation
Landscape management approach is considered one of the most applicable approach in the world to protect natural resources and conserve biodiversity. The approach has much to offer, particularly in biodiversity-rich areas where local people expect the landscape to contribute to food production, employment generation, business opportunities, and conservation.
Landscape Character Assessment is a well-established and widely used method for managing landscape. This method integrates natural, cultural, social, factors of landscape with perceptual-aesthetic aspects of people and experts. Due to its multidimensional aspects it is becoming popular worldwide. But the method is developed on the aspect of England where factors and process were designated according to the environmental condition, socio-economic status and the data availability of developed country which is completely different in developing countries.
These divergent circumstances make difficulties in the application of the same data and process from the method to apply in developing countries. So, the main challenge of this research is to find the answer of how to modify Landscape Character Assessment tool in making characterized area and involve local people’s value to develop a new methodological approach for managing landscape of Teknaf peninsula as well as developing countries.
To find the answer of the challenge the following objectives are:
1) To classify landscape with specific character for making spatial knowledge.
2) To find out convenient social and perceptual factors in context of Teknaf by involving local people.
To achieve the research objectives, two types of data were collected: physical character data and socio-cultural data. Physical character data sets are associated with the watershed area, landform type and vegetation categories and socio-cultural data sets are related to local peoples’
socio-economic status, service perception and preferences for particular landscape character area.
Data were analyzed through ArcGIS, TNTmips and SPSS.
The study identified the four unique Landscape Character Area (LCA is an area where several types of character can meet and make a distinguishable area). The character areas are termed as plain grass land area, plain relief homestead garden area, high land forest area and mixed land mosaic area. The study has also identified the key characteristics and the
distribution of Landscape Character Type (LCT is the particular type of character that can happen in several LCA) which proved that those data are able to classify landscape into specific character area.
The study assesses the service values for different LCT from each LCA by calculating the number of households’ perceived provisional services. The study found the highest service value is 64 for homestead garden that means it is the most used and important area to local people and lowest is 4 for social forest area.
The research evaluated the preference score for different LCT from each LCA and ranked them by asking local people if they personally felt the necessity and importance of landscape character types.
The study revealed the highest preference score for the homestead garden in every LCA, but the followed scores are differing from LCA to LCA.
The research suggests three types of initiatives could be taken on Teknaf peninsula for managing natural resources. Planning for increasing potentiality of East side of Teknaf by using agricultural field and homestead garden in plain grass land area, social forest in High land forest area. In the west side (plain relief homestead garden area Mixed land mosaic area) required better planning for homestead garden and betel leaf field. The findings of this research are expected to be helpful for decision making and managing natural resources. Since the study was conducted on a particular geography, the results may raise concerns about the generalization of the findings. Further research, therefore, should be carried out covering broader geography. A few additional variables could be added to the proposed methodology.
