KHAIRPUR: Sukhai intently moved about the tunnel farm, plucking out bitter gourds under the harsh, relentless sun.

Sukhai, a 23-year-old intermediate student, is one of several women in her village in district Khairpur battling the effects of climate change through tunnel farming. The agricultural technique extends the growing season of crops by using plastic-covered, greenhouse-like structures to create a controlled environment.
