Lao PDR National Adaptation Plan published

CCRM provided climate change projections for the Lao PDR
Government’s National Adaptation Planning Proces, funded by UNEP and GEF (the Global Environment Facility).

The objective of the assessment was to provide downscaled climate change information across three future periods, for six provinces of Lao PDR, including Phongsaly
and Oudomxay (north), Xiengkhouang and Khammouane (centre), and Champasak and Xekong
(south).

Climate change projections for each Province were created for 2025 to 2050, 2051 to 2075
and 2076 to 2100 to assess recorded changes in climate values between 1980 and 2020. The
approach used was designed to simplify information from the substantial range of climate change
projections used by the IPCC whilst retaining much of the information on the uncertainties
involved.

A background climatic assessment of each of the six Provinces was produced using the ERA5 data
sets for 1980 to 2020. This ERA5 is acknowledged generally as providing the highest quality
global data available and hence offers the most reliable data for use within this NAP. Climate
Change projections were then obtained from the global models within the CMIP5 dataset as this
is used primarily in the IPCC AR5 and downscaled using regional climate models in the CORDEX
data set.
