IELTS Reading Practice: Water Resources Challenges with Global Warming

The IELTS Reading section assesses your ability to understand complex texts and identify key information. One increasingly prevalent topic in recent years is the impact of global warming on water resources. This subject has appeared in several past IELTS exams and, given its growing importance, is likely to feature again in future tests. Let’s explore this theme through a practice reading passage and questions.

Water resources affected by global warming

Reading Passage

Water Resources: The Global Warming Challenge

A. Global warming, primarily caused by human activities that increase greenhouse gas emissions, is having a profound impact on the Earth’s water resources. As temperatures rise, the delicate balance of the water cycle is disrupted, leading to a cascade of effects that threaten the availability and quality of freshwater worldwide.

B. One of the most visible consequences of global warming on water resources is the accelerated melting of glaciers and polar ice caps. These frozen reservoirs have traditionally acted as natural water towers, slowly releasing meltwater during warmer months to feed rivers and replenish groundwater. However, as temperatures climb, glaciers are retreating at unprecedented rates. The initial surge in meltwater may temporarily increase water availability in some regions, but this is a short-lived phenomenon. Once these ice reserves are depleted, the consistent supply of freshwater they once provided will be lost, potentially leading to severe water shortages in areas dependent on glacial meltwater.

C. Changes in precipitation patterns are another significant challenge posed by global warming. While some regions may experience increased rainfall, others face prolonged droughts. This shift in precipitation distribution is not merely a matter of quantity but also timing and intensity. More frequent extreme weather events, such as heavy downpours, can lead to flooding and soil erosion, while extended dry periods strain water resources and agricultural systems. The unpredictability of these patterns makes water management increasingly complex, affecting everything from crop yields to urban water supplies.

D. Rising temperatures also directly impact water quality. Warmer water holds less dissolved oxygen and promotes algal blooms, which can be toxic to aquatic life and render water sources unsuitable for human consumption. Additionally, sea-level rise due to thermal expansion of oceans and melting ice sheets threatens coastal freshwater aquifers with saltwater intrusion, potentially contaminating crucial groundwater reserves.

E. The agricultural sector, which accounts for approximately 70% of global freshwater use, faces particular challenges. Higher temperatures increase evaporation rates from soil and water surfaces, necessitating more frequent irrigation. This increased water demand comes at a time when many regions are experiencing reduced water availability, creating a critical imbalance. Farmers may be forced to switch to more drought-resistant crops or implement advanced irrigation techniques, both of which can have significant economic implications.

F. Urban areas are not immune to these challenges. Many cities worldwide are grappling with how to secure reliable water sources in the face of climate change. Some megacities, particularly in arid regions, are already experiencing severe water stress. As urban populations continue to grow, the pressure on municipal water systems will only intensify, necessitating significant investments in infrastructure and potentially leading to water use restrictions.

G. Addressing these water resource challenges requires a multi-faceted approach. Conservation efforts, improved water management practices, and the development of alternative water sources such as desalination are all part of the solution. However, these measures must be coupled with broader efforts to mitigate global warming by reducing greenhouse gas emissions. The interconnectedness of climate and water systems means that safeguarding our water resources is inextricably linked to our ability to curb global warming.

H. In conclusion, the challenges posed by global warming to water resources are complex and far-reaching. From melting glaciers to changing precipitation patterns, rising temperatures to water quality issues, the impacts touch every aspect of water availability and use. As we move forward, adapting to these changes while working to mitigate their causes will be crucial for ensuring water security in a warming world.

Common Mistakes

When tackling reading passages on complex topics like water resources and global warming, students often make the following mistakes:

1. Overlooking specific details: In questions like True/False/Not Given, it’s crucial to pay attention to precise wording. For example, the temporary increase in water availability due to glacial melting is an important detail.

2. Generalizing information: The passage presents a nuanced view of climate impacts, varying by region. Avoid assuming that effects are uniform across all areas.

3. Misinterpreting cause and effect: Be clear about what causes what. For instance, rising temperatures cause water quality issues, not the other way around.

4. Failing to distinguish between stated facts and inferences: In Not Given questions, be careful not to infer information that isn’t explicitly stated in the text.

5. Overlooking keywords: Words like “initially,” “temporary,” or “approximately” can be crucial in determining the accuracy of a statement.

Vocabulary

1. Profound (adjective) /prəˈfaʊnd/ – very great or intense
2. Cascade (noun) /kæˈskeɪd/ – a succession of stages, processes, or units
3. Unprecedented (adjective) /ʌnˈpresɪdentɪd/ – never done or known before
4. Depletion (noun) /dɪˈpliːʃn/ – the reduction or use of a resource
5. Aquifer (noun) /ˈækwɪfər/ – a layer of rock or soil able to hold or transmit water
6. Intrusion (noun) /ɪnˈtruːʒn/ – the action of intruding
7. Grappling (verb) /ˈɡræplɪŋ/ – engaging in a struggle or confronting a problem
8. Multi-faceted (adjective) /ˌmʌltiˈfæsɪtɪd/ – having many sides or aspects

Grammar Focus

Passive Voice: The passage uses passive voice frequently to emphasize actions and their effects rather than the actors. For example:

• “The delicate balance of the water cycle is disrupted”
• “Once these ice reserves are depleted”

Structure: Present Simple + be + Past Participle

This structure is useful when:

1. The doer of the action is unknown or unimportant
2. We want to focus on the action rather than who does it
3. Describing general truths or scientific facts

Example: “Water resources are affected by global warming.”
