Neem saplings and vegetables sprout up from scrubland in the Clifton district of Pakistan's largest city Karachi, in an area that was once a giant, informal rubbish tip. The urban afforestation project in a government-owned park is one of dozens of state-owned and private planting initiatives in Pakistan, where forest cover lags far behind average levels across South Asia. The aim in Clifton is to counterbalance rapid urbanisation in Karachi, a sprawling port city of some 17 million people where breakneck expansion of roads and buildings means there is less and less space for trees and parkland.

A farmer holds hybrid red chili pepper seeds on his palm as he plants saplings, in Kunri, Umerkot, Pakistan, March 18, 2022. Devastating floods across Pakistan in August and September after several years of high temperatures, have left chilli farmers struggling in a country heavily dependent on agriculture, where officials have estimated $40 billion of flood damages. "When I was a child, the heat was never so intense. We used to have a plentiful crop, now it has become so hot, and the rains are so scarce that our yields have dwindled," farmer Leman Raj, 40, said.
