Large scale irrigation has led to :(i) Changed cropping pattern in man...
Large scale irrigation has led to:
Changed cropping pattern in many regions:
- Large scale irrigation has allowed farmers to grow crops that require more water, leading to a change in the cropping pattern.
- Farmers can now cultivate water-intensive crops like rice, sugarcane, and cotton in regions where these crops were not traditionally grown.
Increased salinisation of soil:
- Irrigation water often contains salts, and when this water is used for irrigation, it can lead to the accumulation of salts in the soil.
- Over time, the salts can build up to harmful levels, resulting in salinisation of the soil.
- Salinisation can negatively affect crop growth and reduce agricultural productivity.
Average reduction in crop production:
- While large scale irrigation has increased the overall agricultural productivity, it has also led to a reduction in crop production in some cases.
- Improper irrigation practices, such as over-irrigation or inadequate drainage, can result in waterlogging and oxygen deprivation in the root zone, leading to reduced crop yields.
Increasing gap between the rich and the poor farmers:
- Large scale irrigation systems often require substantial investment in infrastructure, such as pumps, canals, and pipelines.
- Small-scale farmers may not have the financial resources to invest in such infrastructure, resulting in an increasing gap between the rich and the poor farmers.
- Wealthier farmers who can afford to invest in irrigation infrastructure have a competitive advantage over poorer farmers, leading to further inequality in agricultural production.
Therefore, the correct answer is C: i, ii, iv.
