Climate change increased frequency and intensity of droughts, floods, heat waves and other extreme events directly threaten food productivity and soil health, leading to severe food shortages. Changes in crop yields need to adapt to climate conditions. Changes in climate such as temperature, moisture, pests, weeds, disease and increased CO2 will reduce food production worldwide. Crop yields such as rice, wheat and maize will see a decline when reacting to the rise in global temperatures. Extreme weather is a driver of world hunger. As global temperatures and sea levels rise, the result is more heat waves, droughts, floods, cyclones and wildfires. Those conditions make it difficult for farmers to grow food and for the hungry to get it. Extreme weather is a driver of world hunger. As global temperatures and sea levels rise, the result is more heat waves, droughts, floods, cyclones and wildfires. Those conditions make it difficult for farmers to grow food and for the hungry to get it. Negative impacts of global warming include reduced crop quantity and quality due to the reduced growth period following high levels of temperature rise; reduced sugar content, bad coloration, and reduced storage stability in fruits; increase of weeds, blights, and harmful insects in agricultural crops. Climate risk in agriculture represents the probability of a defined hydro-meteorological hazard affecting the livelihood of farmers, livestock herders, fishers and forest dwellers.

Climate change affects food production, availability of and access to food, food quality, food safety, diet quality, and thus people's nutrition and health. Climate change may further slow progress towards a world with food security for all. Climate change affects agriculture in a number of ways; including through changes in average temperatures, rainfall and climate extremes with an important impact on soil erosion, changes in pests and diseases, changes in atmospheric carbon dioxide, changes in the nutritional quality of some crops. The effects of climate change on agriculture will, in turn, have significant implications for food security, and thus human diets and nutrition. As climate change affects the ability to move food from production to markets, access to diverse, high-quality diets may become more limited. 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 risk in agriculture represents the probability of a defined hydro-meteorological hazard affecting the livelihood of farmers, livestock herders, fishers and forest dwellers.

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. Climate change has significant adverse effects on production of the world's key staple crops. In particular, weather extremes in terms of shocks in both temperature and precipitation during crop growing months have detrimental impacts on the production of the abovementioned crops. 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. Agriculture sector in India is vulnerable to climate change. Higher temperatures tend to reduce crop yields and favor weed and pest proliferation. Climate change can have negative effects on irrigated crop yields across agro-ecological regions both due to temperature rise and changes in water availability. Aggravated climatic factors will ultimately decline plant productivity, which will result in increased prices and unaffordable rates for the common population. The absence of mitigation and adaptation measures may result in lower farm income by 12-40% in the coming years.
