Geographical factors for mangrove growth:

1Van Coastline = around 7100km + coastal ecology of mangrove.
2High salinity of coast → mangroves are salt pherent rhizohaline species and hence grow. Eg vasai mangrove in mumba high.
3Presence of continental shelf = provide transitional zone
4Tidal impact = regular high and low tides = space for mangrove distribution through uniparity Eg sundarbans.
5Saline soils = flourishing of mangrove. Eg Hiren mangrove.

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.
