Final answer:
Non-scientific factors contributing to food shortages include inadequate welfare programs, black market activities, and systemic issues in government macroeconomic policies, which are often influenced by social and economic structures.
Step-by-step explanation:
Non-scientific factors causing food shortages include a range of issues linked to economic and social policies. Notably, Nobel Prize-winning economist Amartya Sen emphasizes that food insecurity is often caused by the failure of government macroeconomic policy. Such policies can lead to issues such as inadequate welfare programs, which fail to ensure the equal distribution of available food resources, especially in regions of poverty. Furthermore, problems like the black market can undermine official food distribution systems, leading to shortages in official channels. Moreover, systemic problems such as oppression and the socio-economic mechanics within certain capitalism structures can exacerbate the situation, leading to uneven food distribution.
