Explanations:The Graded Response Action Plan (GRAP) is a comprehensive strategy designed to address the severe air pollution issues faced by the city of Delhi. The plan was developed to mitigate the impact of air pollution by implementing a series of measures that are activated based on the severity of pollution levels. The GRAP is a multi-tiered approach that includes various actions such as the restriction of construction activities, increased public transport services, and the imposition of restrictions on the use of private vehicles.
The need for such a plan arises from the fact that Delhi has been consistently ranked among the most polluted cities in the world. The air quality in Delhi is affected by a variety of factors, including vehicular emissions, industrial pollution, construction dust, and agricultural burning in neighboring states. The GRAP aims to address these issues by implementing a series of measures that are activated based on the severity of pollution levels.
The GRAP is divided into four levels, each with a set of actions that are triggered when pollution levels reach certain thresholds. These levels are designed to ensure that appropriate measures are taken to reduce pollution levels and protect public health. The plan is implemented by the Delhi government in coordination with other state governments and the Central Pollution Control Board (CPCB).
It is important to note that while other states and union territories in India may have their own environmental policies and plans to address air pollution, the GRAP is specifically designed for Delhi due to the unique and severe nature of its air pollution problems. This makes Delhi the correct answer to the question regarding the state/UT with a Graded Response Action Plan to tackle air pollution.
