The Impacts of Climate Change on Food Security.
In 2010, about one billion people went hungry, with the most vulnerable being the poorest.
The key macronutrients, such as carbs, lipids, and protein, are in short supply. Another billion
people are likely to be suffering from nutrient deficiencies, in which critical micronutrients
such as minerals and vitamins are lacking from their diet, putting their health and mental
well-being in danger. One of the world's most important but under-addressed socioeconomic
and health issues is undernutrition (Horton et al., 2009). Undernutrition has tremendous
human and socio-economic costs, and it disproportionately affects the poorest people,
particularly women and children (SUN, 2010). Hundreds of thousands of people around the
world who were malnourished as children confront numerous issues as they grow older.
When they are youngsters, they are at an elevated threat of disease and mortality, have
problems in learning, and are frequently unable to contribute fully to the social and economic
growth of their families, societies, and countries when they are adults (Nabarro, 2010).
Thanks to a mixture of variables such as raising the occurrence and severity of climate-
related hazards, falling agricultural productivity, and lower output in susceptible locations,
climate change threatens to worsen preexisting concerns to food security, welfare, mounting
sanitation and health concerns, growing water shortage, and escalating disputes over limited
resources, all of which would result in new international emergencies and further migration
(Solomon, 2007). Climate change is projected to have an impact on all aspects of food
security, including production, accessibility, sustainability, and consumption.
Modifications in agricultural production, as well as alterations in agricultural land, influence
, the global food supply. Influence on food production, in combination with other factors,
could alter food prices, limiting poor people's accessibility to food marketplaces and reducing
nutrient intake.
Moreover, reduced water quality and quantity in some locations could lead to more
sanitation and health issues, such as diarrhea, which, when combined with shifts in vector-
borne illness dynamics, can grow malnourishment and significantly impact dietary use.
Weather extremes jeopardize food production as well as local economies. Improvements in
severe weather due to climate change, including droughts and floods, would aggravate this
tendency and have a serious effect on households that rely on climatic conditions occupations
like downpour crops and livestock husbandry. 2007 (Schmidhuber and Tubiello). Changes in
climate encompass both temperature increase and its side effects, such as glacial melt, intense
storms, and more water shortages. Global warming refers only to the Earth's rising surface
temperature, whereas climate change encompasses both warming and its side effects, such as
melting glaciers, heavier rainstorms, and more frequent drought. To put it differently, global
warming is an indicator of the far broader climate change problem caused by human activity.
One more differentiation between global warming and climate change is that these days when
scientists or government servants talk about global warming, they most often imply human-
caused temperature increase resulting from the rapid rise in carbon dioxide and other
greenhouse gases from human beings burning fossil fuels, petroleum, and gas. Climate
change, on the other contrary, can refer to both human- and natural-caused changes, such as
glacial periods. Apart from fossil fuel burning, humans can contribute to climate change by
releasing aerosol pollution into the atmosphere, which scatters sunlight and cools the
temperatures, or by changing the Earth's topography, such as from carbon-storing woodlands
