A dried up corn field in Kabacan on April 10, 2016 in Cotabato, Mindanao, Philippines. 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.
