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. Moderate warming and more carbon dioxide in the atmosphere may help some plants to grow faster. However, more severe warming, floods, and drought may reduce yields. Livestock may be at risk, both directly from heat stress and indirectly from reduced quality of their food supply. Changes in temperature and rainfall, shifting pests and diseases, and increasingly frequent extreme weather events will affect food production and security globally. Emissions from food production could be reduced by encouraging healthier diets, reducing food waste, and changing farming and land management practices. 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. On farms, climate change is reducing crop yields, the nutritional quality of major cereals, and lowering livestock productivity. Substantial investments in adaptation will be required to maintain current yields and to achieve production and food quality increases to meet demand.

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. Several adaptation strategies such as heat- and water stress-tolerant crop varieties, stress-tolerant new crops, improved agronomic management practices, improved water use efficiency, conservation agriculture practices and improved pest management, improved weather forecasts, and other climate services. 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 development of improved varieties such as early maturing, drought and heat tolerant are necessary to sustain the productivity under changing climate. It is very likely by incorporating such adaptation techniques, the production can increase under moisture stress and extreme temperatures. Increased atmospheric CO 2 levels has led to higher crop yields but has also resulted in reduced nutritional value of crops. Climate driven changes in pests, plant diseases and weeds can also result in lower crop yields and nutritional value. They require fewer herbicides or fertilizers and are more resistant to water logging or droughts. Reduced chemical inputs contribute to nature protection, and thus adaptive species are a winning solution in terms of climate change and agriculture. Unfortunately, climate change impacts, such as higher temperatures, droughts, more extreme events, sea-level rise, and elevated levels of carbon dioxide, are making the task of increased food production much more difficult by decreasing the quantity as well as the quality of our food supplies

Increased temperatures altered rainfall patterns, and extreme weather events all have a substantial impact on agriculture. These changes result in lower agricultural yields, degraded soil, erosion, and biodiversity loss.

Adopting sustainable agricultural methods like conservation tillage, cover crops, integrated pest control, and rotational grazing are some of the possible responses to climate change in agriculture.

In addition, investing in irrigation infrastructure and technology, improving soil health, and implementing agroforestry practices can all help lessen the impact of climate change on agriculture. Climate-resilient varieties and breeds are also being developed and used.

Reducing the effects of climate change on agriculture requires adaptation. To lessen the effects of altering weather patterns and other environmental factors, agricultural systems must be modified.

Sadly, the negative effects of climate change, such as rising temperatures, droughts, more severe weather, sea level rise, and increased carbon dioxide levels, are making it much harder to produce more food by reducing both the amount and quality of our food supply. Agriculture contributes to and is a cause of climate change, but it is also a component of the solution. To reduce greenhouse gas emissions and aid in the storage of carbon, agricultural practices must be modified. Ecosystems that are controlled by agriculture are also vital socioeconomic issues for humans. Therefore, it is crucial to implement sustainable agricultural practices that not only reduce greenhouse gas emissions but also promote biodiversity and protect natural resources. By doing so, we can ensure food security for future generations while mitigating the impacts of climate change on our planet.

In this regard, it is crucial to consider human response to appreciate and quantify the effects of climate change on agriculture and food supply. All in all, agricultural systems are dynamic, and producers and consumers must constantly adapt to changes in crop and livestock yields, food prices, input costs, resource availability, and technological innovation. Within this perspective, research and events on the physical and financial impacts of climate change on agriculture around the world have been included in this literature survey in chronological order. In addition, it is important to address the social and economic impacts of climate change on agriculture, particularly for small-scale farmers, who are often the most vulnerable. Therefore, policies and programs should be implemented to support these farmers in adapting to the changing climate and improving their livelihoods. It is crucial to take a holistic approach when addressing the impacts of climate change on agriculture, considering not only the physical and financial aspects but also the social and economic implications. This requires a collaborative effort between policymakers, researchers, and farmers to develop effective strategies for adaptation and resilience building in the face of climate change.

To maintain productivity in a changing environment, improved cultivars such as those that mature earlier and are more tolerant of heat and drought must be developed. It is highly likely that by implementing such adaptation strategies, production will rise in conditions of moisture stress and high temperatures. Although increased agricultural yields have been achieved as a result of higher atmospheric CO2 levels, this has also diminished the nutritional content of foods. Lower agricultural yields and nutritional value may also be a consequence of changes in pests, plant diseases, and weeds brought on by the climate. They are more drought and waterlogging tolerant and use less fertilizer and pesticide. Decreased chemical inputs help to safeguard nature, making adaptive species a successful strategy for combating climate change and agriculture.

Due to drought, heat waves, flooding, an increase in pests and plant diseases, and decreased food yields and nutritional quality, climate change's effects on agriculture may reduce crop yields. Many adaptation techniques, including crop types that can withstand heat and water stress, stress-tolerant novel crops, improved agronomic management techniques, increased water usage efficiency, conservation agriculture practices, enhanced pest control, and other climate services. With its impact on food production, pricing, and security, climate change further complicates issues with food security. Water scarcity or excessive heat can hinder crop development, lower yields, and have an impact on irrigation, soil quality, and the ecology that supports agriculture.
