Why the share of agricultural sector in total water used in the country is expected to decline?
The agricultural sector currently accounts for the highest share of water utilisation in the country, using 89 per cent of surface water and 92 per cent of groundwater. This usage far exceeds the limited shares of the industrial and domestic sectors.
However, in the future, the share of agriculture is expected to decline. This is because, with development, the shares of industrial and domestic sectors in the country are likely to increase. As these sectors expand and consume more water, the relative proportion of total water used by agriculture will decrease.
Explanation
The answer is derived directly from the first paragraph of the provided context. While agriculture currently dominates water usage, the text explicitly states that 'in future, with development, the shares of industrial and domestic sectors in the country are likely to increase.' This increase in other sectors logically leads to a relative decline in the agricultural sector's share.
Solution Steps
Step 1: Identify the current water usage statistics for agriculture (89% surface, 92% ground) from the text.
Step 2: Locate the specific reason for future changes in the text: 'with development, the shares of industrial and domestic sectors... are likely to increase'.
Step 3: Synthesize the points to explain that the rise in industrial and domestic shares will cause the agricultural share to decline.
