Impacts of climate on Agriculture and Food production
Introduction
Climate change has adverse effects on different resources on earth such as water, which greatly
sustains life on this planet. The changes which takes place in the biodiversity, biosphere and he
natural resources greatly affects the quality of life and human health. Thought the 21st Century,
India Punjab Ludhiana is projected to experience warming above the global level.
Agriculture production greatly depends on the weather and climate change. Any possible
changes in precipitation, temperature and carbon dioxide concentration has very significant
impacts on the growth of crops. The overall effects of climate change on India Punjab
Ludhiana food production is considered to be moderate to high with successful adaptation
and enough irrigation programs.
Climate is constantly changing, and the signal which shows that the changes which are taking
place can be evaluated over a range of spatial and temporal scales. Climate refers to an
integration of complex weather conditions which are averaged over a period of time, which
are usually expressed in terms of both the average of the weather which is expressed by
properties such as radiations, temperatures, wind, atmospheric pressure, cloudiness, rainfall etc.
and distribution or the variation of the given weather properties.

Global warming/climate change refers to the gradual increase in the overall temperatures of the
earth's atmosphere which is generally attributed to the greenhouse effects which is as a result of
increased levels of CFCs, Carbon dioxide and other pollutants (Singer, 2018). From the studies
carried out, the Earth has been warming from the South Pole to the North Pole. Since 1906, the

global mean surface temperature has increased by more than 0.9 degree Celsius (1.6 degrees
Fahrenheit) in the sensitive Polar Regions the average increase is more than 0.9oC.
Causes of climate change
Human activities are the main causes of global warming since the mid-twentieth century, mostly
because of:
i) Fossil fuels
The widespread use of fossil fuel is the main cause of global warming, This is because as gas,
coal, and oil burn carbon dioxide is produced which is the most essential greenhouse gas in the
atmosphere. Also in the process of burning this fossil fuels, nitrous oxide is produced (Hawken,
2016).
ii) Deforestation
Due to the global population increase, human beings have been forced to clear some of the
forested areas to create room for agriculture and other human activities such as industrialization.
The exploitation of forests has a great impact on climate change. Trees are known to control the
climate through the absorption of Carbon dioxide from the atmosphere.
iii) Intensive farming
Intensive farming is another cause of global warming, the utilization protection fertilizers, and
products together with the ever increasing number of livestock. The wastes of sheep and cattle
contain methane, the agricultural fertilizers generate nitrous oxide emissions (Victor, 2015).
iv) Mining
