Open scan (p.40)

Main Body

According to Forest Survey India state of forest report, India has a 4991 km² mangrove area in India.

Geographical factors in growth of mangrove:

1high salinity environment
2continue mud, flow and new sediment deposition
2anaerobic root environment, i.e. low O2 conditions

(ii) high energy requirement

direct solar insolation, for growth.

Mangrove adaptation to challenging geographical area:

1sculent water & prevent ocean salt excretion proven leaves
2salt secreting glands to remove salt supply
3specific root system to support water flood condition (eg) Rhizophora, prop root stilted
4viviparity to reproduce in flood condition
5Bitter root to support ocean tidal action inflow and large size.

Role in coastal ecology:

1slime dine stabilization divert strong root network
2mitigating tropical cyclone impact
3castle & leads formation of beach by melting sand destabilizing
4ecological species as well as taught stock sites, kale, leaves, medicine etc

Threats – revealed n/e (5) NABA predicted item n/e between 1993 and 2019 degradation and reduction

(d) 2021 ISFR highlighted slight decline in mangrove. Our Indian has launched initiative like MSFR, global mangrove alliance etc to promote mangrove conservation and stability saturation coastal ecology.

As a senior officer in the Ministry, you have access to important policy decisions and upcoming big announcements such as road construction projects before they are notified in the public domain. The Ministry is about to announce a mega road project for which the drawings are already in place. Sufficient care was taken by the planners to make use of the government land with the minimum land acquisition from private parties. The compensation rate for private parties was also finalized as per government rules. Care was also taken to minimize deforestation. Once the project is announced, it is expected that there will be a huge spurt in real estate prices in and around that area. Meanwhile, the Minister concerned insists that you realign the road in such a way that it comes closer to his 20-acre farmhouse. He also suggests that he would facilitate the purchase of a big plot of land in your wife’s name at the prevailing rate which is very nominal, in and around the proposed mega road project. He also tries to convince you by saying that there is no harm in it as he is buying the land legally. He even promises to supplement your savings in case you do not have sufficient funds to buy the land. However, by the act of realignment, a lot of agricultural lands has to be acquired, thereby causing a considerable financial burden on the government, and also the displacement of the farmers. As if this is not enough, it will involve cutting down of a large number of trees denuding the area of its green cover. Faced with this situation, what will you do? Critically examine various conflicts of interest and explain what your responsibilities are as a public servant.
