Abstract Soil erosion is an inevitable geomorphic process that aids in evaluating and analyzing the erosive and hydrological status of the watershed. The present investigation focuses on the qualitative evaluation of the hydrologic and erosive status of eighteen watersheds (area > 10 km2) of south Andaman using drainage morphometric studies. The objective of the present study was addressed with the aid of GIS and remote techniques. The results suggest that four watersheds such as Burmanallah, Carbyn, Burataga, and Dhania showed low levels of soil erosion. Whereas, seven watersheds via., Putatang, Colinpur, Jirkatang I, Dhanikhari, Jarawa I, Jarawa III, and Tirur exhibited high levels of soil erosion. The rest of the seven watersheds via., Bhagoda, Bilap, Bill, Jirkatang II, Jarawa II, Jarawa IV, and Mannarghat were prone to moderate levels of soil erosion. Further, the findings from forty years’ time series climate-water balance modelling reaffirm that more than 60% of rainfall divulges into the adjacent seas as surface runoff. Thus, the copious amount of fresh water and loads of nutrient-rich fluvial influx at the shallow depths of coastal frontiers aid the mangrove to respond.

The outbreak of coronavirus disease was first noticed in the Wuhan city in Hubei province of Central China. This disease has now spread all over the world, including the USA, Italy, France, UK and India. Due to its global effect, the World Health Organization has declared this as a pandemic. To date, there is no reliable cure and vaccination for this Virus. This disease has made substantial scale damage to both life and property all over the world. To stop the community spread of COVID-19, countries around the world, including India, opted for a complete lockdown of a month or half. This sudden lockdown has forced to shut down all activities of manufacturing, processing, transportation, trade and commerce. This lockdown has left many vulnerable groups stranded without food and shelter and livelihood. This study tried to review the preparedness and mitigation effort of the Government of India towards containment of COVID-19 spread and analyze the impact of lockdown on the economy of India. This study is entirely based on the secondary sources of data, which is further processed and represented using MS-office. The data analysis shows that the government of India has acted swiftly towards containing and checking the spread of COVID-19. Moreover, it has been found that this lockdown will bring the GDP to as low as 2.5% and there will be a collective loss of more than Rs. 43 lakhs crores. Further, this disease has left many vulnerable groups stranded in their places without food and livelihood. Finally, this study has suggested providing the best possible protective gear and types of equipment to medical workers who are sacrificing their lives for the betterment of humankind.
