In order to estimate the proportion of damaged crops in eastern, southern, and central Africa, numerous research have been conducted; however, the findings indicate that it is hard to identify with certainty which crops are the most dangerous; According to forecasts, climate change will have a significant impact on crops like (wheat, rice, and corn), which provide 80% of the calories we all consume. If we can’t manage this loss or lessen it; we won’t have as much of the items that we already use significantly. However, each country’s crops are diverse and are impacted differently.
Global issues like agriculture and climate change are interconnected.
Whereas there are many ways that climate change impacts agriculture, including: changes in temperature, rainfall, and extreme weather fluctuations (like heat waves); changes in pests and diseases; changes in atmospheric carbon dioxide and near-surface ozone concentrations; changes in the nutritional value of some foods; and changes in sea level.
For some vulnerable groups, especially the poor, the danger of food insecurity is also projected to rise as a result of climate change.
Additionally, the creation of greenhouse gases such as carbon dioxide and methane by livestock is to blame for future land infertility and the extinction of native species.
Agriculture is already being impacted by climate change, and these effects are unevenly distributed worldwide. Future climate change is likely to have a detrimental impact on food output in low-latitude nations, whereas it could have either positive or negative consequences in northern nations. negative.
Whether it be through greenhouse gas emissions from human activity or the conversion of non-agricultural areas like forests into agricultural land, agriculture plays a role in climate change. Between 20 and 25 percent of the world’s annual emissions in 2010 were attributable to the conversion of forests into agricultural land.
Climate continues to play a significant role in agricultural output as well as the state of soil characteristics and natural ecosystems, despite technical advancements like improved crops, genetically modified organisms, and irrigation systems. Rather than global climate patterns, factors in local climate patterns influence how the climate affects agriculture. Since 1880, the temperature of the Earth’s surface has risen by 1. 5 degrees Fahrenheit (0. 83 degrees Celsius).
Thus, according to experts in agriculture, any evaluation should take into account each locality separately.
The Food and Agriculture Organization (FAO) has stated that human-caused greenhouse gas emissions are a primary driver of these changes and that they pose a threat to our ability to achieve global food security, end poverty, and achieve sustainable development.
Changing rainfall patterns, droughts, floods, and the geographical redistribution of pests and diseases are all effects of climate change, according to a 2018 report. Additionally, the enormous amounts of carbon dioxide absorbed by the oceans cause acidification, which has an impact on the health of our oceans and those whose livelihoods and nutrition depend on them.
The two agricultural crops most impacted by climate change worldwide are rice and wheat.
