In recent years it has become clear that climate change is an inevitable process in many parts of the world and has a negative impact on agriculture and food systems particularly in Sub-Saharan African countries. Climate change involves variations in temperature and precipitation across the globe. The environmental changes associated with climate change have a significant impact on the food supply chains food environments and food systems in general. These changes affect food production, storage, processing, marketing, availability, promotion, affordability and quality along the food value chain. Consequently, climate change affects global food security and peoples’ income especially, in developing countries where the predominance of rain-fed agriculture in much of these countries results in food systems that are highly sensitive to rainfall and temperature variability. The narrative review aimed at evaluation of published literature to understand the impact of climate change on food systems across the globe. Literature search from 2000-2019 was carried out using key words and key phrases in Google search Engine. Elsevier agriculture journals, JSTOR journals, Google Scholar, ResearchGate, Nature and Climate Change journals. More than 120 relevant publications were retrieved of which 44 were scrutinized and used for this publication. The study found that increased rainfall and temperature affect food availability, utilization, crop yields, food markets, food prices, consumption patterns and food insurance. The review recommended that all stakeholders should adopt relevant policies about climate change mitigation and adaptation options along different food value chains. This will enable farmers to produce sufficient food required to feed the projected 9.8 billion people by 2050 thus contributing to sustainable development goal number two: -End hunger, achieve food security and improved nutrition and promote sustainable agriculture.
