The IELTS Reading section is one of the critical components of the IELTS examination. This section evaluates your ability to understand and interpret academic texts. One common topic that frequently appears in the IELTS Reading section is the effects of climate change on global food security. Given the increasing relevance and urgency of climate change issues, it is highly probable that this subject will appear in future IELTS exams. This article will guide you through a well-structured reading practice on this topic, complete with questions and answers.
Reading Passage
The Impact of Climate Change on Global Food Security
Climate change poses a significant threat to global food security, affecting the availability, access, utilization, and stability of food systems worldwide. Changes in temperature, precipitation patterns, and extreme weather events impact agricultural productivity, while also influencing the socio-economic conditions that underpin food security.
Firstly, temperature increases can reduce crop yields. For instance, wheat production is highly sensitive to temperature changes, with studies projecting a 6% decline in global wheat yields for every 1°C rise above the optimum growing temperature. Additionally, higher temperatures lead to increased evaporation and reduced soil moisture, impacting water availability for irrigation.
Moreover, altered precipitation patterns can lead to both droughts and floods. Droughts diminish water resources, crucial for irrigation, while floods can destroy crops and infrastructure. A notable example is the 2011 drought in the Horn of Africa, which exacerbated food insecurity and led to severe humanitarian crises.

Extreme weather events such as hurricanes and typhoons also disrupt food security. Such events can devastate agricultural areas, leading to immediate food shortages and long-term economic hardships. Typhoon Haiyan, which struck the Philippines in 2013, resulted in massive agricultural damage and left millions in need of emergency food assistance.
Climate change’s impact extends beyond crops to livestock as well. Heat stress reduces livestock productivity and increases vulnerability to diseases. Consequently, regions heavily dependent on livestock, such as sub-Saharan Africa, face heightened food insecurity risks.
Lastly, food supply chains are affected. Transportation disruptions, storage losses due to extreme temperatures, and market volatility make it harder for food to reach consumers, especially in vulnerable regions.
Addressing these impacts requires a multifaceted approach. Sustainable agricultural practices, climate-resilient crop varieties, and improved water management can enhance food security. International cooperation is also vital in supporting vulnerable areas through technological transfer and financial aid.
