Abstract
The present food system (including production, transportation, processing, packaging, storing, retail, and consumption) is a source of nutrition for the great majority of the world population in addition to supporting the livelihoods of about 200 million people. Food supply per capita has increased by more than 30% since 1961, this is accompanied by more use of nitrogen fertilizers (showing an increase of about 800%) and water resources for irrigation (with an increase of more than 100%). Global food security will continue to be an international concern for the coming 50 years and even beyond. Crop yield has fallen in many areas recently due to decreasing investments in infrastructure and research, as well as due to growing water scarcity. Climate change is a global concern irrespective of borders. The poor nations are highly vulnerable to climate change and are at high risk. Food security is directly dependant on the food chain and the associated food system process. All dimensions of food security could be affected by climate change in complex ways. Approximately, 15 countries are highly vulnerable to food insecurity due to climate change, from Asia and Africa. Most of these nations are not able to cope with or counter the impact of climate change on an urgent basis. However, some countries have developed their national strategies and adaptation plans to alleviate the negative impacts of climate change.
