Question 23
Examine the impact of rainfall on agriculture and on domestic water supplies.
Worked Solution & Example Answer:Examine the impact of rainfall on agriculture and on domestic water supplies. - Leaving Cert Geography - Question 23 - 2021
Step 1
Impact on Agriculture
Answer
Rainfall plays a crucial role in agriculture, affecting crop growth, yield, and farming practices. Adequate rainfall ensures sufficient soil moisture, which is vital for the germination of seeds and the growth of plants. It promotes healthy root development and allows crops to access essential nutrients.
However, excessive rainfall can lead to waterlogging, which can damage roots and hinder growth. It may also increase the risk of diseases such as root rot due to prolonged wet conditions. Conversely, insufficient rainfall can cause drought, leading to stress on plants, reduced crop yields, and potentially famine in severe cases.
Farmers often adapt their agricultural practices based on rainfall patterns, utilizing irrigation systems during dry spells and implementing drainage systems in areas prone to flooding.
Step 2
Impact on Domestic Water Supplies
Answer
Rainfall significantly affects domestic water supplies as it replenishes aquifers and surface water bodies such as lakes and rivers. Regions with sufficient rainfall typically have higher water availability for household use, agriculture, and industry.
In urban areas, rainfall contributes to stormwater management systems, which can capture and store water for future use. However, in areas with low rainfall, water scarcity can become a pressing issue, leading to reliance on water imports or investments in desalination and water recycling technologies. Moreover, variability in rainfall can cause fluctuations in water quality due to runoff, which may carry pollutants into water supplies.
