This study aims to examine the intervention strategies for sustainable food security in the horn of Africa, with particular focus to Kenya. The long term and persistent food security problem in Kenya and the sub-Saharan Africa region as a whole does not reflect the World Food Summit Commitment of cutting down the world hunger rates by 50% by the year 2015. This trend requires intervention strategies to be put in place to curb the situation. Studies done in Kenya on food security have mainly concentrated on the levels and causes of the food security and the analysis of the problem. This study is therefore designed to examine various intervention strategies including national capacities and policies, support efforts employed such as donor funding, research and development and participation by stakeholders such as farmers, Regional and International mechanisms as strategies in addressing food security problem in the Horn of Africa. The study also examines the food security situation in the Horn of Africa the efforts employed towards sustainable food security in Kenya and critically analyses the role of policies and institutions in addressing food insecurity in the Horn of Africa as well as in Kenya. The Factors were analyzed employing theories of liberalism and structural financial approach. It was found out that trade liberalization agreements and financial ties with international financial institutions restricted countries in the Horn especially Kenya from developing an efficient food security policies. Government programs were found to be inefficient because SAPs prevent government from subsidizing vulnerable sectors particularly food security policies. The outcome of poor governance, political instability, poverty, climate change impacts by droughts and floods, land degradation and ineffective policy mechanisms in the Horn of Africa did not pave way for the improvement of the food security situation. States in the Horn of Africa therefore must promote and support agricultural transformation programmes through significant investments, appropriate policies and effective institutions, with a view to enhancing value addition and competitiveness, increasing strategic staple production and ensuring social and environmental sustainability of the food and agricultural systems. This study adopted a case study research design. Data collected has be from secondary sources. This involved reviewing material sources in the form of journals, books and reports. The collected data has been analyzed thematically by constructing themes that sought to discuss various intervention strategies that work towards attaining sustainable food security in Kenya and the Horn.
