The Lao People’s Democratic Republic (Lao PDR) is exposed to significant climate and disaster risks. The results of this analysis show that the contribution of hydrometeorological information to socioeconomic development in Lao PDR is expected to be very high, particularly due to the potential benefits for the energy and tourism sectors and their contribution to GDP. The results of this study support the conclusion that hydromet information is critically important for Lao PDR and that investments in the hydromet sector are expected to be highly profitable from socioeconomic perspective.
