Climate change is an imbalance in normal climatic conditions such as heat,
wind and rain and The increase in carbon dioxide (CO2) emissions, which is the main
component of greenhouse gases on the surface of the earth. The amount of gas (CO2)
increases as a result of industrial activity, which depends on the cycle of fossil fuels ),
As well as the exhaust of cars and irrigation machines, which helped to distinguish
each area of the Earth from the other, and change in the climate is a change in the
overall atmosphere of the Earth as a result of the emission of greenhouse gases,
which leads to the warming of the surface of the earth. Climate change refers to a
change in the state of the climate and can be determined by changes in the average or
volatility of its characteristics. The agricultural sector is considered to be one of the
sectors that will be negatively affected by this phenomenon. Climate change is
expected to affect agricultural land productivity, from affecting natural, chemical and
biological properties to pest, insect, disease and other problems to crop yield .
The problem of the study was limited to the following :
The unfriendly human behavior resulted from a change in the structure of the
greenhouse gas components of the atmosphere, which in turn led to a marked
imbalance in temperature and precipitation. This led to the effects of climate change,
including positive and negative impacts on agricultural production.
The study aims to clarify :
The impact of climate change, such as the phenomenon of global warming and
the components of greenhouse gases, which are composed of the atmosphere on
temperature, rainfall, structure of crop structure, average productivity and total
productivity, This is in addition to extrapolating farmers' views on the causes and
effect of climate change on agricultural production and how to reduce the negative
effects of climate change.
The study relied on several sources of data :
1- published and unpublished secondary data from Central Laboratory
Information Center for Climate, Department of Agricultural Meteorology, Central
Administration of Agricultural Extension, as well as data published on the web .
2- Preliminary data for a field study through a specially designed survey
questionnaire
3- The study also relied on descriptive and quantitative methods in analyzing the
data and presenting its results in percentage percentages, annual growth rate, change
rate, seasonal guide, and simple linear regression equations for the relevant variables
and correlation with the prevailing climate changes in the studied area .
The study reached several results, including :
1- The concentration of CO2, CH4 and N2O gases in the atmosphere has
increased. In 1985, they reached 0.0345%, 0.0001666% and 0.0000304% in the
atmosphere respectively. This percentage increased to a maximum of about 0.04% in
2015, 0.0001845 %, 0.0000328% in the atmosphere.
2- Sources of climate change in the cultivated area of the sample farming
(weather) have been divided into five elements: The first element dealt with the
burning of agricultural waste with a relative importance of about 37.58%. The second
element dealt with the removal of trees with a relative importance of about 22.93%.
While the third item dealt with car exhausts with a relative importance of about
21.02%. While the fourth element dealt with factory smoke with a relative
importance of about 10.2%. The other component dealt with other sources (excessive
use of pesticides, natural disasters, etc.) with a relative importance of about 8.28% of
the total frequency in the sample .
3- temperature control devices were divided into six elements: the first element
dealt with the increase of municipal fertilization with a relative importance of about
25.2%. The second element dealt with increasing the irrigation rate with a relative
importance of about 23.9%. While the third element dealt with agriculture in the
house with a relative importance of about 19.4%. While the fourth element dealt with
reducing the period between irrigation with a relative importance of about 17.7%.
The fifth component dealt with the expansion of woodland planting with a relative
importance of about 10.7%. The last element dealt with other sources (the meeting of
two or more elements of the previous elements, unthought elements) with a relative
importance of about 2.8% of the total frequencies in the sample studied .
Based on the above, the study recommends the following :
1- The efforts of individuals and institutions should combine to reduce and
clean up car exhausts, irrigation machines and factory chimneys .
2- Expansion of the cultivation of wood forests, especially around industrial
zones and new cities .
3- Holding meetings and seminars directed by the agricultural extension to
support farmers and introduce them to the risks of pollution and increase the
concentration of greenhouse gases and their impact on Egyptian agriculture .
4- Encouraging investments in protected agriculture such as agriculture and
spending.
5- Encouraging scientific research in the field of forecasting and future climate
change, as well as developing and cultivating all modern technology that is
compatible with these changes.
