The Swachh Bharat Abhiyan, which was launched in India in 2014, is a nationwide campaign aimed at improving sanitation and cleanliness in Indian cities. The campaign has had a significant impact so far, but it has also faced a number of key challenges: 1. Lack of infrastructure: One of the biggest challenges has been the lack of infrastructure such as garbage bins, public toilets, and waste management systems. Many cities do not have an effective waste collection and disposal system, leading to piles of garbage on streets and open spaces. 2. Poor public awareness: Another challenge has been the lack of awareness among the public about the importance of cleanliness and sanitation. Many people still do not understand the impact of their actions on the environment and the health of their community. 3. Cultural habits: In many parts of India, littering and open defecation is seen as a cultural norm. Changing these habits can be difficult and requires a long-term effort. 4. Limited resources: The government has limited resources to invest in infrastructure and other initiatives to improve sanitation and cleanliness. As a result, progress has been slow in some areas. Despite these challenges, the Swachh Bharat Abhiyan has had a significant impact in Indian cities. The number of public toilets and waste management plants has increased, and there has been a greater emphasis on cleanliness in public spaces. The campaign has also raised awareness about the importance of sanitation and cleanliness, which could lead to lasting changes in public behavior.
