Answer Strengths Gaps Keywords

Introduction

Mangroves are halophytic trees that grow in coastal areas and provide various ecosystem regulators and cultural services. According to ISFR, their area has increased but their density has decreased.

Main Body

Geographical Factors responsible for Mangrove:

Large coastal zone of approximately 7500 km

Presence of major river deltas like Ganga, Sundarbans, Krishna-Godavari, Avaram, Andaman Nicobar

Suitable tropical and subtropical climate

Suitable soil condition

Non-foreclame/invasive species that affect them

Historical precedence

Climate change and Mangrove impacts:

Mangroves provide coastal communities protection from tsunamis, high tides, food and shelter

Melting of glaciers leading to more discharge of freshwater, altering saline levels

Climate change resulting in more extreme events like cyclones, leading to destruction of mangroves

Changing suitable climate for growth of mangrove

Climate change leading to pressure on local communities which increases pressure on mangrove resources

Destruction feedback loop created between climate change and mangrove destruction

Q4 (b) The pathology laboratory of a hospital has five pathologists. Samples arriving at the laboratory for a particular test are randomly assigned to one of them. An evaluation of the performance during the previous month gave the following counts shown in the table below: Pathologist A B C D E Number of tests done 850 1000 750 900 1050 Number of reported errors 12 15 11 17 10 Table Supporting: IAS Mains Optional Management Paper 2 Year 2020 The director of the hospital wanted to know whether the proportion of errors in the pathological tests assigned to the five pathologists differ. State appropriate null and alternate hypotheses for the question above. Carry out the test of hypothesis at 5% level of significance and describe the result x2 (chi-Squared) Distributed: Critical Values of x 2 Significance level Degrees of freedom 5% 1% 0.1% 1 3.841 6.635 10.828 2 5.991 9.210 13.816 3 7.815 11.345 16.266 4 9.488 13.277 18.467 5 11.070 15.086 20.515 6 12.592 16.812 22.458 7 14.067 18.475 24.322 8 15.507 20.090 26.124 9 16.919 21.666 27.877 10 18.307 23.209 29.588 Table Supporting: IAS Mains Optional Management Paper 2 Year 2020
