Safe and sustainable sanitation in slums has immeasurable benefits to women and girls in terms of their health, safety, privacy and dignity. However, women do not feature in most of the schemes and policies on urban sanitation. The fact that even now the manual scavenging exists, only goes to show that not enough has been done to promote pour-flush toilets and discontinue the use of dry latrines. A more sustained and rigorous campaign needs to be launched towards the right to sanitation on a very large scale. This should primarily focus on the abolition of manual scavenging.

With reference to the above passage, consider the following statements:
1. Urban sanitation problems can be fully solved by the abolition of manual scavenging only.
2. There is a need to promote greater awareness on safe sanitation practices in urban areas.
Which of the statements given above is/are correct?

The correct option is 2 only.

Let us analyze the statements step-by-step based on the provided passage:

Step 1: Analyzing Statement 1 ("Urban sanitation problems can be fully solved by the abolition of manual scavenging only.")
The passage mentions that a sustained campaign needs to be launched focusing on the abolition of manual scavenging, and highlights the benefits of safe and sustainable sanitation in slums. However, stating that urban sanitation problems can be fully solved by the abolition of manual scavenging only is an extreme generalization. The passage mentions other elements like promoting pour-flush toilets, discontinuing dry latrines, and involving women in schemes and policies. Therefore, Statement 1 is incorrect because it oversimplifies the solution to a complex issue by pointing to a single factor.

Step 2: Analyzing Statement 2 ("There is a need to promote greater awareness on safe sanitation practices in urban areas.")
The passage highlights that "a more sustained and rigorous campaign needs to be launched towards the right to sanitation on a very large scale." A large-scale campaign naturally involves promoting greater awareness among the public and policymakers regarding safe sanitation practices, health, safety, privacy, and dignity. Therefore, Statement 2 is a correct and logical inference from the passage.

Consequently, only Statement 2 is correct.
