Of the mangrove loss during this period, I estimate that commercial aquaculture accounted for 28% of total mangrove loss across all nations resulting in approximately , ha of mangrove forest. The protective mangrove buffer zone helps minimize damage of property and losses of life from hurricanes and storms. In regions where these coastal fringe forests have been cleared, tremendous problems of erosion and siltation have arisen, and sometimes terrible losses to human life and property have occurred due to destructive storms.
Increasing the area of mangrove forests can lead to more drag on incoming waves and storm surges, thus reducing their effects. Mangrove forests can reduce storm surges by % (Blankespoor et al., ; Sheng and Zou, ; Zhang et al., ). It is proven that the mangrove forest has contributed largely to reducing the loss of life and damage to property from storms and cyclones as it reduces the impact of waves, storm .
on the soil surface can also trap mineral sediment, and contribute to vertical accretion (Cahoon et al., ). Water currents during ebb tides are too low to re-entrain the sediment. Thus, the mangrove structure causes sediment accumulation (Furukawa and Wolanski, ). Storms and extreme high water events can alter the mangrove sediment. A Riparian Mangrove Fringe (RMF) is a term used in the Mangrove Act ((7), F.S.) to classify when mangroves are exempt to trim or not. A RMF is where mangroves growing along the shoreline of the property owner do not extend more than 50 feet waterward.

Storm protection is an important regulating service provided by mangrove forests because they can shield inland property and lives during tropical cyclones.
Theoretical as well as empirical. Storm protection is an important regulating service provided by mangrove forests because they can shield inland property and lives during tropical cyclones. Theoretical as well as empirical research shows that mangroves provide protection from storm surge.
But whether mangroves protect inland static property during storms is less explored. Can mangroves minimize property loss during big storms?: an analysis of house damage due to the super cyclone in Orissa. By Saudamini Das.
Abstract. This paper estimates the storm protection benefits on residential property in the Kendrapada district of Orissa (India) due to the mediation of mangrove forests during a super cyclone ().

By combining GIS data with census information, the paper examines the mangrove Author: Saudamini Das.
The researchers found that flooding racks up about $ billion every year in property damage, but that the presence of coastal mangroves, a salt-tolerant species of. Abstract: Storm protection is an important regulating service provided by mangrove forests because they can shield inland property and lives during tropical cyclones.

In Collier County, the team analyzed flood damages for storms and found that annual flood damages would increase by 25% should the county suffer the loss of its mangrove forests. Mangroves are most effective in flood risk reduction where they are abundant and located in front of areas with high densities of people and property.
A waxy coating on the leaves of some mangrove species seals in water and minimizes evaporation. Small hairs on the leaves of other species deflect wind and sunlight, which reduces water loss through the tiny openings where gases enter and exit during photosynthesis.
Mangroves annually reduce property damage by more than $US 65 billion and protect more than 15 million people. If current mangroves were.
Mangrove forests are among the most threatened habitats in the world, and mangrove loss is rampant across the globe. Thailand has lost 84 percent of its mangroves, the highest rate of mangrove loss of any nation, while the Ivory Coast, Guinea-Bissau, Tanzania, Mexico, Panama, Malaysia, Myanmar, Pakistan, and the Philippines have each lost more.
A preeminent mangrove restoration ecologist, Robin Lewis, has referred to these sites as “mangrove heart attacks” (it is worth reading about this further in Marine Pollution Bulletin, v.p.).” “This is not always the case, however.
Cyclones can cause mangrove loss even when mangroves are relatively un-impacted. Large bands of thick mangrove forests can act as a natural defense against storms, breaking high winds and waves and significantly reducing the storms' impacts on the shore.
waves can lose up to 2/3 of their original height when they hit a mangrove forest. When potentially catastrophic waves hit, mangroves can even save lives. Mangroves protect people, houses and farmland from natural disasters such as storms, typhoons, floods and tidal waves. The trunks and branches of the mangroves act as a barrier, helping reduce the impact of waves, flooding and strong winds.
Intense storm events can also have both destructive and constructive impacts on mangrove ecosystems. The intensity of storms in a particular coastal zone is likely to be influenced by mangrove position in relation to storm track, storm characteristics (e.g., wind velocity, storm intensity radius of maximum wind) and degree of exposure (Krauss et al.Piou et al.Zhang et al.
Mangroves seem to reduce surge-related damage in the leeward side of the forest, and reduce wind and swell waves in coastal areas (McIvor et al., a, McIvor et al., b). However it remains unclear whether mangroves can reduce wind velocity and thus wind damage from storms.
The aim of this study was to shed light on this issue. Losses per cyclone for communities with 6m of mangroves per metre of coastline were double that of communities protected by 25m per m of mangroves. In the former group, losses are somewhere between and months of economic activity. In the latter, the extra mangroves kept cyclone impacts down to between and months.
Climate change is extending the range of mangroves. The tropical trees are thriving farther north and south than ever before. Scientists say that's actually helping limit damage during. “The mangroves provide a lot of friction so they slow that flooding down,” Geselbracht said.
The study only looked at storm surge reduction, but the mangroves with their thick canopy also help. • Wide areas of mangroves can reduce tsunami heights, helping to reduce loss of life and damage to property in areas behind mangroves.
• The dense roots of mangroves help to bind and build soils. The above-ground roots slow down water flows, encourage deposition of sediments and reduce erosion.Mangrove roots can break up the force of a storm surge, soaking up some of its energy and protecting people living on coasts from cyclone damage.
Yet it is a challenge to effectively value and.Mangroves can substantially reduce the vulnerability of the adjacent coastal land from inundation and erosion. However, climate change poses a large threat to mangroves. This paper quantifies the coastal protection provided by mangroves for 42 developing countries in the current climate, and a future climate change scenario with a one-meter sea.
