The world produces much more food than is required to provide everyone with an adequate diet, yet 800 million people, almost one person in seven do not have enough to eat. Approximately
44% of the Kenyan population suffers from chronic under-nutrition, with an increasing mortality rate of children due to malnutrition, impaired physical and mental development and morbidity. Regional bodies working in Africa and Kenya are rapidly responding to challenges of food security within the above-mentioned context by: encouraging local producers to improve food production and supply hence improving food security both at the household and national level; through collaboration with the government to mitigate volatile food price effect within the local markets and, further improving the capacity of production in the local agricultural sector. The objective of this study is to analyze the role of regional organization in food security in Kenya in order to inform all the involved stakeholders on the situation and the right courses of actions to be taken, examine the challenges facing regional organizations in improving food security, and to establish the strategies of regional bodies on food security in Kenya. The study employs the use of the Post-Developmental Theory emerges as an important perspective for understanding matters of food security. Post-development theory is a useful theory framework in investing the interaction between food security organizations, the population and the government, both as actors in food security sustainability. The study adopts secondary method of data collection. and qualitative analysis to analyze data obtained from the field. Qualitative data analysis will consider a non-experimental design; this will focus on assessing the roles, the challenges and strategies of food security in Kenya. The findings will be used as basis for making analysis and recommendations on how best government and the help from citizens can influence food security positively.
