Emerging Livelihood Vulnerabilities in an Urbanizing and Climate Uncertain Environment for the Case of a Secondary City in Thailand

Abstract

Increasing flood risks in Thailand are leading to new challenges for flood management and subsequently for livelihoods, which are still significantly agricultural. Policy makers prefer building flood protection infrastructure over utilizing non-structural measures like urban planning regulations to mitigate risks. We argue that unplanned urbanization intensifies flood risks and livelihood vulnerability and may even create new poverty patterns in peri-urban areas. However, urbanization can also strengthen the adaptive capacity of people in flood risk areas by providing more secure employment opportunities. We assess the livelihood vulnerability of Pra Lab, a peri-urban area of Khon Kaen City in Northeast Thailand, using a qualitative and quantitative analysis. The study relies on a vulnerability index developed from a household survey and rainfall statistics, complemented by household in-depth interviews. We further identified factors of unplanned urbanization in Khon Kaen City and Pra Lab through interviews with relevant local government offices. Our findings show that Pra Lab's household livelihoods are moderately vulnerable to flood due to high financial (i.e., income, debts) and physical vulnerability (i.e., housing, urban systems, infrastructure). Major factors of unplanned urbanization that contribute to flood risks are lack of land use regulations, inefficient monitoring of land and house elevations, reduced pervious surfaces, ineffective water governance and insufficient wastewater treatment.

City Profile: Khon Kaen, Thailand

“…Despite the widespread adoption of decentralization reforms in developing countries, urban and regional development remains, in many countries, under the aegis of central governments. Government resources and private investments continue to pour into metropolitan areas, particularly the capital cities (Beringer & Kaewsuk, 2018). As a result, locational policies are too difficult for the secondary cities to pursue.…”

Whose climate change adaptation ‘barriers’? Exploring the coloniality of climate change adaptation policy assemblages in Thailand and beyond

“…As Marks (2015: 634) finds, then, pathways of vulnerability to flooding have been engineered for decades, including through 'the rise of local politicians-cum-businessmen' which has led to the fire sale of land for industrial and housing projects and the expansion of road-centric development. This pattern was especially egregious in the Bangkok Metropolitan Region, but has also played a part in the uneven, haphazard development of smaller cities such as Buriram (Marks & Lebel, 2015) and Khon Kaen (Beringer & Kaewsuk, 2018), among others (Friend et al, 2014).…”

Intelligent Environment Monitoring System for University Laboratories

“…To detect pollutants in real-time, the authors of Reference [2] proposed environmental lab-on-a-chip monitoring and focused on future perspectives to overcome monitoring challenges using printing technologies. Considering flood risks in Thailand, the authors studied the livelihood vulnerability in Northeast Thailand [3]. Inefficient monitoring of land and house elevations was shown to be the major factor leading to flood risks.…”
