Hunger is not only caused by food insecurity, but also by a combination of natural, social, economic, and political factors. Natural resources necessary for human survival, such as freshwater, oceans, forests, and soils, are declining. Climate change further degrades these resources as severe weather events, including droughts, become more frequent and affect harvests, resulting in reduced food availability.

Poverty, inequality, war, and conflict are also major drivers of hunger. These factors affect people’s ability to access food, increase food prices, disrupt production, and may force communities to leave their homes. Therefore, addressing hunger requires coordinated efforts in food security, nutrition, social support, and sustainable community development.
