Pakistan’s climate migrants face tough odds

When floodwaters submerged their farm in 2011, Kashif Abro and his family sought refuge in Karachi, Pakistan’s largest city, around 250 miles away. 

They knew their stay would be temporary: They only needed to wait for the water to recede before returning to their four acres of land in Kamber Shahdadkot district in Sindh province, where they grew rice, wheat, and vegetables.
