Climate change affects farming in a number of ways, including through changes in average temperatures, rainfall, and climate extremes changes in pests and diseases, changes in atmospheric carbon dioxide and ground-level ozone concentrations, changes in the nutritional quality of some foods. Climate change further poses a challenge to food security challenges with its influence on food production, costs, and security. Excessive heat or shortage of water can impede crop growth; reduce yields, and influence irrigation, soil quality, and the ecosystem on which agriculture depends. The effects of climate are also seen in declines in pollinating insects and increases insecurity risks, such as the expansion of pest species and disease distribution. Extreme climate events can also directly disrupt food transport, market accessibility, and storage infrastructure.

Agriculture production will be affected by increasing temperatures, changing rainfall patterns, and more frequent and intense extreme weather events. These will have direct effects on crop growth and their need for water, as well as soil fertility, water supply for irrigation, and prevalence of pests and diseases. Climate change can disrupt food availability, reduce access to food, and affect food quality as projected increases in temperatures, changes in precipitation patterns, changes in extreme weather events, and reductions in water availability may all result in reduced agricultural productivity. Higher temperatures and changing precipitation patterns will severely affect the production patterns of different crops. Agricultural productivity will also be affected due to increased carbon dioxide in the atmosphere. All these changes will increase the vulnerability of the landless and the poor. Climate change further poses a challenge to food security challenges with its influence on food production, costs, and security. Excessive heat or shortage of water can impede crop growth; reduce yields, and influence irrigation, soil quality, and the ecosystem on which agriculture depends. The effects of climate change on agriculture can result in lower crop yields and nutritional quality due to drought, heat waves and flooding as well as increases in pests and plant diseases. Extreme high temperature and drought accelerate the evaporation of soil water, the decomposition of organic matter and the loss of nutrients, thus reducing land productivity; high-temperature weather increases the risk of farmers suffering from heat-related traumatic injury and chronic diseases

The extra CO2 accounts for 30% of agricultural output at present. Plants need less water with more CO2, thus water use efficiency of crops has improved. Crops can be grown in drier climates. Irrigation water goes further. There are a lot of benefits.

I agree with Dr Donald Batten that an increased temperatures could affect livestock health, resulting in reduced milk, egg and meat production and even fatalities; increased cooling costs for producers. Higher CO2 levels may result in greater productivity from crops. Extreme high temperature and drought accelerate the evaporation of soil water, the decomposition of organic matter and the loss of nutrients, thus reducing land productivity; high-temperature weather increases the risk of farmers suffering from heat-related traumatic injury and chronic diseases. Climate change may push 90 million Indians towards hunger by 2030. It has listed a decline in agricultural production and disruption in the food supply chain, reason for future crisis. Climate change can disrupt food availability, reduce access to food, and affect food quality. For example, projected increases in temperatures, changes in precipitation patterns, changes in extreme weather events, and reductions in water availability may all result in reduced agricultural productivity. Heat waves can cause heat stress in both animals and plants and have a negative impact on food production. Extreme periods of high temperature are particularly harmful for crop production if they occur when the plants are flowering – if this single, critical stage is disrupted, there may be no seeds at all. Changes in ozone, greenhouse gases and climate change affect agricultural producers greatly because agriculture and fisheries depend on specific climate conditions. Temperature changes can cause habitat ranges and crop planting dates to shift and droughts and floods due to climate change may hinder farming practices. Climate change further poses a challenge to food security challenges with its influence on food production, costs, and security. Excessive heat or shortage of water can impede crop growth; reduce yields, and influence irrigation, soil quality, and the ecosystem on which agriculture depends. Climate change can affect agriculture in a variety of ways. Beyond a certain range of temperatures, warming tends to reduce yields because crops speed through their development, producing less grain in the process. And higher tem- peratures also interfere with the ability of plants to get and use moisture.

Excessive heat or shortage of water can impede crop growth, reduce yields, and influence irrigation, soil quality, and the ecosystem on which agriculture depends
