This study aims to explore twin objectives. Initially, the study scrutinises the consequences of various pollution control acts and protocols signed by India to improve the air quality and then the study involves itself to investigate the aftermath of COVID-19 lockdown on the air quality of highly populated Mumbai city of India. The empirical analysis is facilitated by the application of Poirier’s Spline function approach on the secondary data compiled from the Maharashtra Pollution Control Board (MPCB). The corresponding structural shifting points are identified through the CUSUM of squares (CUSUMQ) test. The empirical results disclose that Kyoto Protocol and lockdown have positively influenced the air quality. This study ends with suitable policy prescriptions.

India is one of the largest tea producers and consumers in the world. Around 70% of Indian tea is consumed by domestic consumers. The world famous Darjeeling and Assam tea are India’s pride. Once India was the top exporter of tea in the global market, currently, it is lagging behind China, Kenya, and Sri Lanka. In the global arena, Indian tea is facing stiff competition from China, Kenya, and Sri Lanka. With this backdrop, the present study aims to investigate twin objectives. First, the changing growth pattern of India’s tea export is investigated. Along with this, the impacts of trade openness on India’s tea export are also scrutinized. The entire study is conducted based on the secondary data, compiled from the various issues of Handbook of Statistics on Indian Economy published by Reserve Bank of India. The data are compiled for the period 1987–1988 to 2018–2019. The investigation of the first objective is facilitated by the Poirer’s Spline function approach. On the contrary, for the exploration of the second objective, we have calculated the “trade openness index.” The study concludes that initially with trade openness Indian tea industry was benefitting but the growth rate of tea export gets reduced over time. It is surprising that in the post-EXIM-2002–2007 phase the rate of growth of India’s tea exports has declined sharply. The study ends with suitable policy prescriptions.

Indian textiles have a history of fine craftsmanship, and because of that, it has its own global appeal and international demand. India has its own extensive base of raw material and manufacturing. This makes India the second-largest textile exporter in the world after China. India's share in the global textiles and apparels trade was approximately 5% in 2017. In 2017, India's textile industry contributes 7% of total industry output and employs about 45 million people directly. Its contribution to the country's GDP and export earnings in the same year was 2% and 15%, respectively. With this backdrop, the present chapter aims to investigate twin objectives. Initially, the changing growth pattern of India's readymade garment export is investigated. Along with this, the impacts of trade openness on India's readymade garment export are also scrutinized. The entire study is conducted based on the secondary data, compiled from the various issues of “Handbook of Statistics on Indian Economy,” published by “Reverse Bank of India.” The data are compiled for the period 1987–1988 to 2018–2019. The investigation of the first objective is facilitated by the “Poirer's Spline function approach.” On the contrary, for the exploration of the second objective, we have calculated the “trade openness index.” It is measured as the sum of export and import as a percentage of GDP. The study concludes that the Indian readymade garment industry shows a declining growth rate and the industry is benefited from trade openness. The study ends with suitable policy prescriptions.
