Abstract
Exposure to climate change related weather shocks is often considered an important driver of internal and international migration. We evaluate whether alternative strategies to adapt to these shocks mitigate migration intentions of individuals through a discrete choice experiment. Individuals are presented with a hypothetical prolonged drought situation and afterwards with a randomly assigned adaptation solution. By assessing responses before and after the assignment of the adaptation strategies, we will measure the impact of climate change adaptation on migration intentions and comparison across individuals will inform about the relative effectiveness of each strategy.

Experimental Design

Experimental Design
The intervention is a discrete choice experiment designed as a randomized control trial in random sample of around 4350 individuals in 145 villages. The sample is representative for rural villages in Senegal and has a focus on the regions of Matam, Kaolack, and Sedhiou. Individuals will be randomly assigned to one of the four treatment arms, which indicate hypothetical adaptation scenarios:

i. An irrigation system is installed in the village
ii. Drought resistant seeds are provided to farmers
iii. Non-agricultural employment opportunities emerge
iv. Drought relief is provided to households in the form of food or cash assistance
