CLIMATE AND FOOD SECURITY
Journal Title: Българско списание за обществено здраве (Bulgarian Journal of Public Health) - Year 2016, Vol 0, Issue 2
Abstract
In the decades to come, our global food system will face unprecedented strains. On the one hand, demand for sustainable and nutritional food production will continue to increase as the world’s population grows. On the other hand, climate change will produce higher temperatures, changes in rainfall patterns, and more frequent natural disasters that will reduce the growth in global food production by an estimated 2 percent per decade for the rest of this century. One of the most important consequences of climate change could be its effects on agriculture. It is expected to reduce the quantity of food harvested, which could lead to higher food prices and reduced consumption. Climate change can alter agricultural production and regional food availability, which affects diet and body weight. Climate change increases the risk and intensity of disasters, such as floods and drought, which are likely to impact on the poorest in low and middle income countries. These climate disasters are most likely to affect those who are vulnerable and already have poor nutrition – women and children – leading to food and nutrition crises. Undernutrition could increase by 20 per cent by 2050 according to the Intergovernmental Panel on Climate Change. Climate change will disrupt food availability, decrease access to food, and make utilization even more difficult. Stability is defined as the absence of fluctuation in availability, access, and utilization, and a changing climate has significant implications for this component of food security. Extreme weather, higher temperatures, floods, droughts and rising sea levels linked to climate change are threatening people‘s access to food over the long term. The negative impact from climate change on agriculture could subject another 600 million people to malnutrition by 2080.
