The right to adequate food is a fundamental human right. It is realized when every person has physical and economic access at all times to adequate food or means for its procurement. Nonetheless, food systems currently are not guaranteeing the right to adequate food for all individuals resulting in global hunger and food insecurity. Notably, vulnerable populations are among the most affected. This study will explore how food systems can be more inclusive to ensure the right to adequate food for vulnerable populations by carrying out a case study on homeless street children in urban areas of Ethiopia. The study will employ qualitative methods of data collection and action research with street children and various stakeholders. This study is innovative in its focus on hard-to-reach population groups that lack policy and research representation. Furthermore, it will generate knowledge by identifying how representation and empowerment of vulnerable groups can be improved within food systems to promote sustainable food systems and sustainable development of societies.
