Uemura conducted the fieldwork at Luang Prabang World Heritage Office (DPL) in Lao PDR from Mar. 13 to May 18. The objectives of this fieldwork are: 1) visualization of the landscape changes in ZPP-Ua; 2) analysis of the landscape changes; 3) surveys on reasons behind the landscape changes; and 4) assistance of the work of ICT section.

During the first half of the fieldwork, Uemura conducted visualization of the landscape changes in ZPP-Ua, and analysis of the landscape changes. Before the visualization, he identified and addressed some issues regarding the data on buildings for analysis. Especially, incorrect data on building architecture type and building condition were considered significant issues. In the workshop which was held on Mar. 21 to share and discuss the current situation, the issues, as well as the temporary result of the landscape changes in ZPP-Ua, were discussed by the participants (Figure 2). Following the workshop, Tokyo Tech team and DPL conducted a telephone conference and discussed the result of the workshop and future activities. With regard to the issue of building architecture type, the cause of the issue was the lack of ICT staff’s understanding of the characteristics of architecture type. Thus, Tokyo Tech team recommended the head of Building Architecture Division to organize training for the ICT staff. After that, Uemura created documents about the characteristics with DPL staff, and they revised all the data on architecture type in ZPP-Ua referring to building photos entered into ArcGIS software. With regard to the issue of the building condition, the cause of the issue was that ICT staff evaluated the building condition without any criteria. Therefore, Tokyo Tech asked the head of the Building Architecture Division to come up with some important criteria to evaluate building condition. After that, Uemura and ICT staff created a data collection form of building condition, and then they tested data collection and modified the form based on a discussion within the team.

In the latter half of the fieldwork, Uemura conducted surveys on building materials and roof materials to identify the reasons behind the landscape changes. Questionnaires regarding building materials and roof materials were used to collect data from local residents. First of all, he put ID number to existing buildings in the core six villages between 2010 and 2017, visualized and analyzed the data using ID number. Next, he discussed the result of the analysis with DPL staff, and they identified samples for surveys. After that, Uemura surveyed the reasons behind the landscape changes in six core villages with ICT staff with two kinds of questionnaires which were developed by Tokyo Tech team in 2010 (Figure 3). As a result, they could get a total of 140 answers to the questionnaires from the samples. For example, in terms of the result about building materials, it was identified that local residents thought traditional materials were more affordable, more durable and easier to get them than non-traditional materials.

Also, Uemura conduced four activities as the assistance of the work of ICT staff: 1) installation of the latest version of Linux into a new PC; 2) backup of the data on Heritage DB: 3) development of thematic maps showing visualization of the data on building attributes in ZPP-Ua in 2017; and 4) development of UIs of Heritage DB using PHP. The development of UI of the Heritage DB is currently ongoing.

For the last fieldwork activity, Uemura presented the results of these fieldwork activities at DPL (Figure 4). In the discussion after the presentation, he was given some advice on how to analyze landscape changes and local residents’ opinions on building materials. Through the fieldwork activities, he could consider the relationship between the management of the World Heritage Site and development from various perspectives such as DPL, tourists and local residents.

Through this fieldwork, Uemura achieved the objectives by cooperating with DPL staff. From now on, he is going to further analyze the survey results, revise the data on building condition in ZPP-Ua and develop the UI of the Heritage DB.
