rickets, a nutritional disease — nutritional disease Children with rickets. The disease, which most commonly strikes children, causes bone deformities such as bowlegs. Rickets is caused by a lack of vitamin D or calcium.

Wars and social problems are primary human-driven factors that precipitate famines and contribute to nutritional disease by disrupting the availability and distribution of food.312

The Impact of Warfare

Warfare is the most common human cause of famine. It exacerbates food insecurity through several mechanisms:31
* Direct Destruction: Combatants often deliberately destroy crops, livestock, and food supplies to weaken the opposition.31
* Distribution Disruption: Through the use of blockades, sieges, and the destruction of transportation infrastructure, war prevents the movement of essential foodstuffs to populations.31
* Supply Chain Interference: Conflicts, such as the Russia-Ukraine War, disrupt global grain shipments and increase the costs of fuel and fertilizer, making food unaffordable for vulnerable regions.42

Social and Economic Factors

Social problems and political instability significantly hinder access to adequate nutrition:42
* Economic Decline: Poverty, inequality, and weak national economies limit a population's ability to purchase food, even when it is available.42
* Political Systems: The nature of a country’s political system and its management of resources play a critical role in preventing or worsening food shortages.31
* Systemic Issues: In wealthier nations, factors such as systemic discrimination, low wages, and the creation of food deserts contribute to food insecurity.2

Addressing these issues requires a commitment to finding peaceful resolutions to conflicts and implementing social safety nets to protect vulnerable households.2
