We analyze whether Tanzanian households engage in internal migration as a
response to weather-related shocks. Our findings confirm that climate shocks
lead to a higher probability of migration by reducing agricultural yields, which
in turn induces households to send their members away in order to spatially
diversify their income. This effect is, however, low, since a 1% reduction in agricultural
income induced by weather shock increases the probability of migration
by 3% for an average household. What is more, such mechanism is valid only
for households whose income is highly dependent on agriculture, but is not
significant for diversified livelihoods.
