Why rural places matter for regional economic resilience: Insights from agritourism in Northern Thailand

open access: yesSingapore Journal of Tropical Geography, Volume 47, Issue 3, Page 517-539, September 2026.
Research on regional economic resilience has predominantly focused on urban contexts in Europe. This study extends the empirical foundation by examining rural agritourism resilience during the COVID‐19 pandemic in rural Chiang Mai, Thailand. Employing an evolutionary economic geography framework, this research traces the historical development of the ...

Numerical study on surrounding rock control effect of gob-side entry retaining by roof cutting and pressure relief

open access: yesMeikuang Anquan, 2021
To study the influence of roof cutting and pressure relief on the surrounding rock control effect of gob-side entry retaining, numerical simulation was carried out by UDEC software, and the stress and deformation characteristics law of roadway surrounding rock under two states of whether the lateral roof collapsed or not were analyzed. The results show
