HOW TO CONTROL RISE IN SEA SEA LEVEL

1. PROTECTING MANGROVES-

Mangrove is a shrub or small tree that grows in coastal saline water. It protects the coastal areas from erosion and storm surge .

 Eg. Indonesia – Avicennia, Rhizophora, Sonneratia , etc.  Brazil, Malaysia , Sundarbans (West Bengal) aims at protecting them.

2. PROTECT WETLANDS –

 Wetland is a ecosystem where water meets land.They acts as giant sponges, buffer zones for coastal areas in hurricanes and rainstorms.

Eg. The Mid–Atlantic Coastal wetland review is the first in a series that EPA Coastal Wetland Team conducted.

Ramsar Convention.. (IRAN) ,1971

This project aims at improving and protect wetlands from wetland loss and degradation.

 3. ARTIFICIAL ISLANDS –

Constructing artificial islands are also helpful in order to control rise in sea level.

Eg. Maldives, .. The Maldivian government has started a joint venture with architectural firm

Dutch Docklands International is aiming at building  the world’s largest artificial floating island project , and it will stay above water.

The Netherlands have been dealing with these types of issues and found success at adapting to changing sea levels by using water management systems, encouraging use of floating homes and incorporating adaptations into city planning.

Also, there is a massive palm-shaped artificial islands built off the coast of Dubai , or Hong Kong International Airport , which was also built on an artificial island.

4. INSTALLATION OF POROUS ROCK STRUCTURE ON SHORES –

 Hard surfaces prevent water from getting into the ground and lead to an increase in erosion.

Eg.  A  “dolos”  a protective structure against a shoreline in cape town , South Africa is constructed to protect against the erosive force of waves and permeating of water into ground.

5. REDUCE YOUR FOOTPRINT –

The foremost reason of rise in sea level is greenhouse gases or carbon dioxide emissions .So we needed to reduce the amount of greenhouse gases that we produce daily by reducing the use of fossil fuels , less use of energy resources , plant more trees and save trees because trees are helpful in soaking water and reducing the amount of carbon dioxide , and also we needed to reduce our energy use .

6. BUILDING UNDERWATER WALLS –

Building walls at the base of glaciers would stop ice sheets sliding and collapsing , and prevent warm water from eroding the ice from beneath.

Eg, The Thwaites Glacier in Antartica and The Jakobshaven Isbral in Greenland .

By the studies it was found that the Thwaites glacier is likely to be the biggest single source of future sea level rises, could trigger the melting of enough water to raise the sea levels by three meters.

7. ERECTING ARTIFICIAL BARRIERS ON THE SEA FLOOR COULD HALT THE MELTING OF GLACIERS UNDER WATER –

# In a stable glacier a natural barrier is always there prevents warm water from reaching ice sheets.

# The ice sheets is vulnerable when it grounds on a backwards facing slope. Warm water flowing down the slope undercuts the ice , creating instability.

# Building an artificial barrier to block the warmer water reduces the rate of melt , allows the ice shelf to thicken .

# If the shelf advances and thickens enough to reground on the artificial barrier the glacier can start to regain mass.

It was estimated by using these steps and building a structure of this kind would have about 30% probability of preventing a runaway collapse of West Antarctic ice sheets .

So , by these measures and steps the level of sea  rise  may  be controlled .
