Climate change impact on agriculture
Practice Reading Passage
The Growing Challenge: Climate Change and Global Food Security
Climate change is increasingly recognized as one of the most significant challenges facing global agriculture and food security in the 21st century. As temperatures rise and weather patterns become more erratic, farmers worldwide are grappling with new obstacles that threaten crop yields and food production. This shift in environmental conditions is not just a future concern; it’s a present reality that is already impacting agricultural systems across the globe.
One of the primary ways climate change affects agriculture is through alterations in temperature and precipitation patterns. Many regions are experiencing more frequent and severe heatwaves, which can damage crops and reduce yields. For instance, a study conducted by the University of Oxford found that for every degree Celsius increase in global mean temperature, global wheat yields could decrease by 6%. This is particularly concerning given that wheat is a staple food for billions of people worldwide.
Changing rainfall patterns also pose a significant threat. Some areas are facing prolonged droughts, while others are dealing with increased flooding. Both extremes can be detrimental to crop production. In sub-Saharan Africa, where many farmers rely on rain-fed agriculture, unpredictable rainfall has led to crop failures and food shortages. Conversely, in parts of Southeast Asia, more intense monsoon seasons have resulted in flooding that destroys rice paddies, a crucial food source for the region.
The impact of climate change on agriculture isn’t limited to direct effects on crops. It also influences the prevalence and distribution of pests and diseases. Warmer temperatures can allow certain pests to survive in areas where they previously couldn’t, leading to new challenges for farmers. For example, the coffee berry borer, a major pest for coffee growers, has been able to move to higher altitudes in East Africa as temperatures have risen, threatening coffee production in areas that were once too cool for the insect.
Moreover, climate change is affecting the nutritional quality of some crops. Elevated levels of carbon dioxide in the atmosphere can lead to higher yields in certain plants, but this often comes at the cost of reduced nutritional value. Research published in the journal Nature Climate Change revealed that rising CO2 levels could significantly reduce the protein, zinc, and iron content in staple crops like rice and wheat, potentially exacerbating malnutrition in developing countries.
Adaptation strategies are crucial in mitigating the effects of climate change on agriculture. Many farmers are turning to climate-smart agriculture techniques, such as conservation tillage, crop rotation, and the use of drought-resistant crop varieties. In addition, advanced technologies like precision agriculture and genetic modification are being explored as potential solutions to enhance crop resilience.
However, adaptation alone may not be sufficient. Addressing climate change at its root through global efforts to reduce greenhouse gas emissions is essential for long-term food security. International cooperation and policy changes will be necessary to support both mitigation and adaptation efforts in agriculture.
As we face this global challenge, it’s clear that the relationship between climate change and agriculture is complex and multifaceted. The impacts are far-reaching, affecting not just food production but also global economic systems, trade, and human health. Understanding and addressing these challenges will be crucial for ensuring food security for future generations in a changing climate.

Answer Key and Explanations
True – The passage states: “This shift in environmental conditions is not just a future concern; it’s a present reality that is already impacting agricultural systems across the globe.”
False – The passage mentions a 6% decrease, not 10%: “for every degree Celsius increase in global mean temperature, global wheat yields could decrease by 6%.”
True – The passage notes: “In sub-Saharan Africa, where many farmers rely on rain-fed agriculture, unpredictable rainfall has led to crop failures and food shortages.”
Not Given – The passage mentions the coffee berry borer in East Africa but does not discuss South America.
False – The passage states that higher yields from increased CO2 often come “at the cost of reduced nutritional value.”
C – Soil salinity is not mentioned in the passage as a direct effect of climate change on agriculture.
B – The passage states: “Research published in the journal Nature Climate Change revealed that rising CO2 levels could significantly reduce the protein, zinc, and iron content in staple crops like rice and wheat.”
B – This paragraph discusses how temperature increases affect wheat yields globally.
C – This paragraph talks about how warming temperatures are allowing pests like the coffee berry borer to spread to new areas.
