Future food insecurity is projected to be significantly exacerbated by climate change, which will raise food prices and decrease food output. As energy prices rise as a result of attempts to combat climate change, food may become more expensive. Due to drought and rising crop water demand, the amount of water needed for food production may become more scarce. As some regions become climatically unsuited for production, competition for land may increase. Extreme weather events linked to climate change may also cause abrupt drops in agricultural productivity, which would result in sharp price increases.


Agriculture, Climate, Greenhouse gas emissions.


Weather and climate have a big impact on agriculture. Despite the fact that farmers frequently adapt to changing weather and annual unpredictability, there is still a significant amount of local climate adaptation in the form of established infrastructure, local farming practises, and personal experience. As a result, it is expected that climate change will have an effect on agriculture, potentially posing a threat to established farming practises while also offering opportunities for advancement [1].

The majority of earlier analyses of the effects of climate change on agriculture (and other sectors) have concentrated on time horizons towards the end of the twenty-first century, demonstrating the repercussions of anthropogenic climate change that may be averted by reducing greenhouse gas emissions. Due to the inertia of the physical climate system and the time periods over which significant change in human social, economic, and political influences on greenhouse gas emissions could be brought about, it is also important to analyse the impacts of climate change over the next decades. Even if greenhouse gas emissions started to decline right away, there would still be some degree of long-term warming and sea level rise [2].

The long-term mean climate state has a significant impact on the nature of agriculture and farming practises in any given location; the infrastructure and experience of the local farming communities are typically appropriate to specific farming practises and to a specific group of crops that are known to be productive under the current climate. In some circumstances, the best style of farming may alter as a result of mean climatic shifts away from existing conditions, necessitating modifications to current methods in order to sustain production [3].

The temperature of the earth is rising as a result of the unchecked growth of greenhouse gas emissions. Glaciers are melting, there is more precipitation, there are more extreme weather events, and the seasons are changing as a result. Global population and economic growth, along with the growing pace of climate change, pose a danger to food security worldwide. Climate change is quite dangerous to agriculture. Higher temperatures eventually cause lower agricultural yields of desired crops while promoting the growth of weeds and pests. The probability of short-term crop failures and long-term production decreases rises with changes in precipitation patterns [4].

One of the most important issues of our day is climate change, which has significantly changed or is still changing the ecosystems of the planet. Although the world has always experienced some degree of climate change, in the last 100 years or so, the rate of this variation has multiplied. Since the nineteenth century, anthropogenic activities have caused an increase in average temperature of 0.9 °C, primarily as a result of greenhouse gas (GHG) releases into the atmosphere. According to projections, this rise will be 1.5 °C by 2050, or it could possibly be higher given the rate of deforestation, the rise in GHG emissions, and the pollution of the soil, water, and air [5].


Increased livestock production (for meat and other types of revenue), water resource exploitation, and other intensive agricultural techniques have all been brought about by the population's constant desire for food. By releasing GHG (due to agricultural operations) and leading to the contamination of natural resources, this has made the situation even worse. Although forests serve as a sink for CO2, the unregulated rate of deforestation (mostly due to agriculture and development) has unbalanced the carbon cycle.
