COTABATO, MINDANAO, PHILIPPINES - APRIL 10: Ivy Erames, 31, and her daughter Genevie, 11, forage for fruits and and other edible plants around their village in Kabuling, Kabacan on April 10, 2016 in Cotabato, Mindanao, Philippines. Ivy and her family of 7 lives in a poor and underdeveloped farming community in the mountains of North Cotabato province where food aid from government agencies is scarce. "We only eat one meal a day for nearly six months now, if we are lucky enough to sell firewood in the nearby market, then we can buy rice" says Ivy. The heatwave brought on by the El Nino weather phenomenon has severely affected food and water supplies in many countries. Based on reports, 85 percent of the whole Philippines will experience the effects of the drought and around 12 million Filipinos who rely on agriculture will directly be affected. In southern Philippines, where farmers lacked agricultural infrastructures and farming subsidies, the population faced impending hunger during the drought and two demonstrators were left dead and dozens of people injured after police dispersed thousands of drought-hit farmers in early April.
