Final answer:
Developing nations face several obstacles when trying to improve food supply, including limited financial resources and infrastructure, political instability, and restricted access to international markets. These challenges hinder the development of modern agriculture and obstruct efforts to increase productivity and food distribution.
Step-by-step explanation:
When a developing nation is trying to improve its food supply, it may face multiple obstacles, one of which includes limited financial resources and infrastructure. This can manifest as a lack of investment in modern agricultural technologies, insufficient storage facilities to preserve harvested food, and inadequate transportation methods to distribute food effectively. In addition to financial constraints, these nations often struggle with political instability, which can hinder government support for agricultural initiatives and impact the economic environment negatively, making it difficult to secure the necessary investments for agricultural productivity improvements. Moreover, access to international markets may be limited, further constraining the ability to import needed agricultural inputs or export surplus produce, which could otherwise help to improve the national economy and subsequently the local food supply. Therefore, while access to arable land and advanced agricultural technology can be beneficial, they are not always readily available or feasible for developing nations with restricted financial resources and infrastructure.
