Assessing and Comparing Smallholders' Vulnerability to Climate Change Among Countries in the Pan-Third Pole Region

A comprehensive assessment of climate change vulnerability is imperative for formulating effective adaptation strategies and advancing sustainable development goals. As one of the most climate-vulnerable regions globally, the Pan-Third Pole area lacks transnational vulnerability assessments, which poses a significant obstacle to efficient climate adaptation. This study conducted transnational comparisons based on primary micro-survey data collected uniformly across Nepal, Cambodia, Thailand, and Myanmar, which are all located in the Pan-Third Pole region. Evaluating and comparing the vulnerabilities employed an extended framework of climate change indicators. The findings reveal substantial variations in vulnerability among the countries, with Cambodia exhibiting the highest vulnerability, followed by Thailand, Myanmar, and Nepal in descending order, primarily due to differences in exposure. Household exposure to climate change also varied significantly. Sensitivity scores decreased in the order of Nepal > Cambodia > Thailand > Myanmar, with demographic factors, tap water accessibility, and land being the major contributors and sources of differentiation among the countries. Regarding adaptability, Thailand demonstrated the highest adaptability, with human and financial capital as the key differentiators. The outcomes underscore the need for tailored policy measures addressing the diverse vulnerabilities, including enhancing household disaster prevention and capital protection. Furthermore, targeted international investments are crucial for improving adaptability among smallholders in this unique region.
