Practice Reading Test on “How is Climate Change Affecting Global Agricultural Yields?”

Text (Medium Difficulty)

Climate change has emerged as a profound challenge to global agriculture, impacting crop production, livestock, and fisheries. The interplay of temperature changes, altered precipitation patterns, and increased frequency of extreme weather events is creating multiple stressors for agricultural yields worldwide.

For instance, rising temperatures can reduce crop yields directly by shortening the growing season and increasing the likelihood of heat stress, which can inhibit plant growth. In regions like Sub-Saharan Africa, where agricultural practices are heavily dependent on predictable weather patterns, any significant change can be disastrous. Statistical models predict that for every 1-degree Celsius increase in global temperature, substantial crop losses in staple grains such as wheat, rice, and maize could ensue.

Meanwhile, altered precipitation patterns can lead to severe water scarcity or waterlogging. Drought conditions exacerbate water scarcity issues, diminishing the availability of irrigation. The Horn of Africa has experienced recurrent droughts, decimating harvests and compelling pastoralists to travel further distances in search of pasture.

Furthermore, the increasing frequency and severity of extreme weather events, such as hurricanes, floods, and droughts, pose threats to livestock and agricultural infrastructure. The devastation of Hurricane Maria on Puerto Rico’s agricultural sector is a case in point, leading to significant losses in fruit and coffee plantations.

Fisheries are not immune to these impacts. Ocean warming and acidification disrupt marine ecosystems, leading to a decline in fish stocks and altering fishing dynamics. Coastal communities dependent on these fisheries are particularly vulnerable.

Addressing these challenges requires integrated strategies, including the adoption of climate-resilient crops, improved irrigation techniques, and comprehensive disaster management plans. International cooperation and funding are also crucial to support regions disproportionately affected by climate variability.

    • Name three staple grains affected by global temperature increases.

Answers and Explanations

  1. Multiple Choice

    • B. Increasing heat stress: The text clearly states that rising temperatures can lead to heat stress, which affects plant growth.
  2. Identifying Information

    • True: The text mentions that the Horn of Africa has experienced recurrent droughts that decimate harvests.
    • False: Puerto Rico’s agricultural sector suffered significant losses due to Hurricane Maria, not benefits.
  3. Matching Sentence Endings

    • Drought conditions… a. …lead to decreased availability of irrigation.
    • Extreme weather events… b. …pose threats to livestock and infrastructure.
  4. Summary Completion

    • Climate change poses multiple challenges to agriculture by altering precipitation patterns, increasing extreme weather events, and directly impacting yields through temperature rises.
  5. Short-answer Questions

    • Sub-Saharan Africa: This region’s agriculture relies on predictable weather patterns.
    • Wheat, rice, maize: These are the three staple grains mentioned to be affected by temperature increases.

Common Mistakes

  1. Misinterpreting Questions: Ensure you understand whether a statement asks for factual information, writer’s views, or implied meaning.
  2. Time Management: Allocate adequate time to read and understand the text before attempting to answer questions.
  3. Vocabularies: Some candidates may struggle with terminology related to the environment and agriculture. Proper preparation through reading similar texts will help build familiarity.
