ABSTRACT
Climate change is likely to worsen the situation in parts of the world that already experience high levels of stressors to livelihood and food insecurity. The consequences of greater variability of climatic factors like rainfall conditions affect the livelihoods and safety of vulnerable people. Less predictable seasons, more erratic rainfall, unseasonable events or the loss of transitional seasons can decrease food security, the livelihoods of millions of people, and the migration decisions of vulnerable households in areas that are already under climate stress (e.g. from drought, flooding, and temperature variation in areas like the Horn of Africa and parts of Asia). In order to make informed decisions about adaptation planning, development, and a transition to a more climate-resilient future, policy makers and development actors need a better understanding of the linkages among changes in the climate, household livelihood and food security profiles, and migration decisions— particularly in crisis situations.
