Desertification in Africa is forecast to force 60 million people to migrate, within three years, because they can no longer survive where they are.

I think that they will have trouble finding any place to go, especially as population growth all around Africa will fill up the places they might have gone. A few million might survive for a while by moving into wildlife areas and killing the wildlife.

What can we do about this? For the most part, nothing. Serious efforts to curb global heating would take more than three years to make a difference.

However, a strong contraceptive program could easily avert a few million births among the affected populations, even in three years. This won't prevent that regional disaster, but would make it smaller.
