Egyptian farmer Reda Hosseini prepares tea in the village of Shamma in the Egyptian Nile Delta province of al-Minufiyah on November 17, 2015. The fertile Nile Delta provides around a third of the crops for Egypt's population of 80 million and a large part of these crops are exported providing the country with an important source of revenue. Climate change has forced some Delta farmers to abandon their land, while others are trying to adapt by covering their land with beds of sand to isolate against seawater infiltration and grow crops.
