Climate change is affecting agriculture the most. Agriculture is the backbone of India’s economy. In such a situation, climate change is also posing a threat to our economy. The productivity of agriculture is completely dependent on the condition of weather, climate, and water. Agricultural production is affected by the change or change of any of these factors. On one hand, the direct impact of climate change is the decrease in agricultural production and on the other hand the indirect effect is reflected in the loss of income and rising prices of grains.
To save Indian agriculture from the ill effects of climate change, we have to make fair use of our resources and by adopting Indian philosophy of life; we will have to implement our traditional knowledge. Now there is a dire need that we should give importance to such eco-friendly methods in agriculture so that we can maintain the productivity of our soil and save our natural resources.

Climate Change and Impact on Agriculture Essay 1 – (200 Words)
Climate change affects agriculture by direct and indirect means such as impact on crops, soil, cattle, insect-mites etc. The decrease in rainfall duration during the monsoon leads to a decline in productivity of rain fed areas. Cold and frost reduces the production of oilseeds and vegetables. As a result of the cold wave in the month of January in the year 2013, the yield of various foods like mango, papaya, banana, brinjal, tomato, potato, maize, rice etc. was highly affected.
In the year 2017, as a result of the rise in temperature in March, the wheat crops had matured 10-20 days before their scheduled time, which led to a decrease of more than 4 million tonnes of wheat production throughout India. Similarly, in 2018, due to erratic monsoon, rice production was estimated to decline significantly.
Climate change affects agriculture in various ways. Fertile soil, water, favorable environment, protection from insects and mites etc. have an important contribution in increasing agricultural productivity. Each crop requires a proper temperature, proper type of soil, rainfall and humidity to grow, and any of these standards changes, affecting the yield of crops. This is hampering the economic condition of the farmers as well as the nation and the world.
Climate Change and Impact on Agriculture Essay 2 – (300 Words)
Climate change will have a deep impact on agricultural yields. Climate change in India will result in an increase in the productivity rate of crops like sugarcane, maize, sorghum, millet and ragi; while on the contrary, the yield of major crops such as wheat, paddy and barley will decline.
Due to increase in temperature, increase in nitrogen fixation rate in pulses crops will increase. Oilseed crops like yellow mustard, brown mustard, sunflower, sesame, black sesame, linseed, will see a decline in yield while soybean and peanut production will increase. According to an estimate, if the current global rate of warming continues, the production of food-grains in rain-fed areas in India will decrease by 12.5 million tonnes.
In a warm tropical country like India, climate change will result in an increase in the production of fruits like mango, banana, papaya, chiku, pineapple, custard apple, pomegranate, vine, date berries, figs, plum, and watermelon; while apples, potatoes, grapes, and pears will decline. There will also be an unprecedented decline in potato production. Climate change will also have an impact on cropping pattern.
The addition of more energy into the atmosphere will also change the global air pattern. Changes in air patterns will result in uneven distribution of rainfall. In the future, there will be more rainfall in the deserts; in contrast there will be less rainfall in traditional agricultural areas. Such changes will promote huge human migration that will affect the social, economic and political life of human society.
As a result of climate change, grain production will decline due to increase in frequency of natural calamities like flood, drought and storm. Decrease in local food production will lead to starvation and malnutrition which will have long-term effects on health. Shortages of food and water will cause conflicts in the affected areas. People will become more prone to diseases and malnutrition.
Climate Change and Impact on Agriculture Essay 3 – (400 Words)
The Indian economy is primarily based on agriculture. Agriculture is very important for India, as it provides food-nutrition and livelihood security. More than 60 percent people in India depend on agriculture for their livelihood. Agriculture contributes about 17% of the total GDP. Different types of industries depend on agriculture to supply raw materials.
Nowadays the world is struggling with the problem of climate change, due to which India is also not left untouched. Due to climate change, many kinds of changes in the environment such as increase in temperature, more or less rainfall, changes in the direction of the wind, etc. are taking place and leaving a bad effect on the agriculture.
Cause of Climate Change
The main cause of climate change is global warming and the main reason for global warming is the increase in the amount of greenhouse gases such as carbon dioxide, methane, nitrous oxide in the environment. Due to increase in global temperature, polar ice is melting, as a result of which the water level of oceans and rivers is increasing and this is increasing the number of floods and cyclones.
Effect of Climate Change on Agriculture
Due to climate change, the agricultural sector can be affected in many other ways, such as:
- Climate change affects the processes occurring in the soil and the balance of soil-water. Due to the lack of soil-water balance, the dry soil will become drier, which will increase the demand for water for irrigation.
- As a result of climate change affecting aquaculture, there is an increased risk of floods causing huge losses to crops.
- There has been a significant decline in the yield of food crops, which is due to increase in temperature. High temperature reduces the period of growth of crops, intensifies respiration and reduces rainfall.
- Increasing the number of high temperatures, erratic rainfall, floods, famines, cyclones etc. is also creating a crisis for agricultural biodiversity.
- Horticultural crops are more susceptible to climate change than other crops.
- High temperature also affects the yield of vegetables.
- Climate change also indirectly affects agriculture such as increasing weeds.
There are some important powerful adaptation techniques to reduce the impact of climate change on agriculture. Now there is a need to develop such species of crops which have the ability to withstand the pressure of dryness and salinity and which have zero effect from floods and famines. New agricultural techniques such as resource conservation technology, crop diversification, improving pest management, improving weather forecasting system, etc. should be adopted.
Climate Change and Impact on Agriculture Essay 4 – (500 Words)
Climate change refers to any change in climate over a long period of time, whether due to natural variability or as a result of human activity. Earth’s climate is changing day by day. The main reason for this change is due to the intervention of human activities in the form of burning of fossil fuels and agricultural activities. Industrial activities have also been responsible for damaging the environment resulting in the degradation of rain pattern and loss of biodiversity on the Earth.
Due to change in climate the traditional method of farming is largely affected. Frequent natural calamities have left their impact on agriculture and affected the production of food crops in many parts of the world. Despite many negative effects, there are some beneficial aspects of the enhanced greenhouse gas effect such as atmospheric concentration of high CO2 can increase rice, wheat and soybean crop production.
Impact of Climate Change on Agriculture
The major land use around the world is agriculture. Since crop growth, solar radiation is affected by temperature and rainfall, which makes agricultural production highly dependent on climate. Agriculture is also sensitive to climate variability and extreme weather such as droughts, floods, and severe storms. Climate change is projected to have an impact on local agriculture and net results can be detrimental such as persistent drought, salinization of arable land or prolonged growing seasons.
Physical Effects on Plants
Due to the increasing temperature, the rate of transpiration of plants in hot environment, water absorption rate is higher than that due to lack of water in plant tissues, aggregation of salts and metabolic activities will also be affected.
Effect on Genetics
If the annual average growth of the current temperature is sustained by 0.3% to 0.6 % of the current warming due to the increasing effect of green house gases in the atmosphere and its concentration, it may lead to deterioration of biodiversity and genetic degradation in the future. Plant species will not be able to organize themselves in temperature rise.
Factors Related to Future Agricultural Production: Several factors are directly related to climate change and agricultural productivity including:
- Average temperature rise
- Rising temperature of the atmosphere
- Rain, water potential and irrigation
- Changes in climate variability and extreme events
- Rises in sea level
- Pests and diseases
There are several adaptation act options available to combat the climate impacts introduced on agriculture. Some of them are:
- Use of more heat / drought tolerant crop varieties.
- Use of more disease and pest tolerant crop varieties.
- Altered application of nutrients / fertilizers.
- Altered application of pesticides / pesticides.
- To follow the diversification of crops
- Introduction of high yield, early maturing crop varieties in cold regions.
- Change in timing of irrigation and other water management practices.
- To develop an adaptive management strategy at the farm level.
Crop farming can be significantly affected by climate change. Climate change is a good indicator for a decrease in production of colder regions and warmer regions where agricultural production can be increased. The probability of impacts of climate change on agriculture varies from country to country due to its geographical locations.
Long Essay on Climate Change and Impact on Agriculture 5 – (600 Words)
There is a need to study the immediate and far-reaching effects of climate change on agriculture. The challenge of climate change has often become a topic of debate between developed and developing countries in international forums. But the truth is that this problem which adversely affects the farmers suffering from abnormal monsoon or water crisis. People would have been affected by the devastating storms or affected by the severe conditions of drought and floods.
Possible Effects of Climate Change
- By 2100, the productivity of crops will decrease by 10%-40%.
- Rabi crops will suffer more.
- The losses due to frost will decrease, which will result in less loss of potatoes, peas and mustard.
- Due to increase in drought and flood, there will be uncertainty in the production of crops.
- The area of sowing of crops will also change.
- There will be an imbalance in food trade all over the world.
- Fertility and availability of fish and aquatic animals will decrease due to rise in water temperature of oceans and rivers.
- Microorganisms and pests will be affected. If there is an increase in the number of insects, microorganisms will be destroyed.
- The crops in rain fed areas will suffer more because the availability of water for irrigation will also decrease.
Effect on Crops
The potential effects of climate change that are to be seen in the agriculture sector can be of mainly two types – first field based and second crop based. Wheat and paddy are the major food crops of our country. Climate change is impacting their production. Climate change will not only affect the production of crops, but will also negatively affect their quality. A deficiency of nutrients and protein will be found in the grains, due to which the health of human beings will be affected.
Problem of Irrigation
Due to climate change, there will be a serious problem of water supply for the farmers and the frequency of floods and droughts will increase. Not only this, the scarcity of water availability for irrigation can also be felt due to low water flow, salinity, increase in flood and urban and industrial pollution at the mouths of big rivers.
The importance of ground water is the highest in our life. Along with drinking, this water is also used for agriculture. With the increase in population, demand for water has started increasing but it is natural but due to increasing water pollution and lack of proper water management, water has started becoming a problem today. Traditional sources of water in villages are almost exhausted.
Impact of Climate Change on Soil
Soil like other components of agriculture is also affected by climate change. Now, increase in the temperature will affect soil moisture and efficiency. Salinity in the soil will increase and biodiversity will decrease. Declining groundwater levels will also affect its fertility. Due to disasters like floods, soil erosion will be more, whereas due to drought, there will be increasing desertification.
Climate Change and Increasing Number of Pests
Because of climate change the Earth’s temperature is getting increased and this warm climate is helpful in the fertility and growth of various types of pests and insects. Many kinds of harmful bacteria and fungi damage the plants and stop their growth. That hampers the production of grains and vegetables as well as it also leaves its effect on the fruits. These pests and insects not only damage the flora but leave their impact on animals too. Many kinds of diseases and epidemics spread making many of them sick.
Looking on the ill-effects of climate change and warming the people related to agriculture have to take necessary precautions. Farmers have to grow crops that are capable to grow in hot temperature and need less water. The government should take proper initiatives and encourage the citizens to keep concern with this and efforts should be made to control pollution so that the environment will remain pollution free. Scientists should develop seeds that can produce more grains in this changing climate.
